Continuous Neuromuscular Blockade for Bronchopulmonary Dysplasia

OBJECTIVE

 Bronchopulmonary dysplasia (BPD) is the most common late morbidity for premature infants. Continuous neuromuscular blockade (CNMB) is suggested for the most unstable phase of BPD, despite no outcome data. We explored the association between duration of CNMB for severe BPD and mortality.

DESIGN

 Medical record review of children <5 years old admitted from 2016 to 2022 with BPD and one or more course of CNMB for ≥14 days.

RESULTS

 Twelve children received a total of 20 episodes of CNMB for ≥14 days (range 14-173 d) during their hospitalization. Most (10/12) were born at <28 weeks' gestation and most (11/12) with birth weight <1,000 g; 7/12 were of Black race/ethnicity. All were hospitalized since birth. Most (10/12) were initially transferred from an outside neonatal intensive care unit (ICU), typically after a >60-day hospitalization (9/12). Half (6/12) of them had a ≥60-day stay in our neonatal ICU before transferring to our pediatric ICU for, generally, ≥90 days (8/12). The primary study outcome was survival to discharge: 2/12 survived. Both had shorter courses of CNMB (19 and 25 d); only one child who died had a course ≤25 days. Just two infants had increasing length Z-scores during hospitalization; only one infant had a final length Z-score > - 2.

CONCLUSION

 In this case series of infants with severe BPD, there were no survivors among those receiving ≥25 days of CNMB. Linear growth, an essential growth parameter for infants with BPD, decreased in most patients. These data do not support the use of ≥25 days of CNMB to prevent mortality in infants with severe BPD.

KEY POINTS

· This is a case series of neuromuscular blockade for severe BPD.. · Neuromuscular blockade did not improve linear growth.. · Ten out of 12 infants who were on prolonged neuromuscular blockade died..

Delirium Screening in Critically Ill Children: Secondary Analysis of the Multicenter PICU Up! Pilot Trial Dataset, 2019-2020

OBJECTIVES

To determine the patient-level factors associated with performing daily delirium screening in PICUs with established delirium screening practices.

DESIGN

A secondary analysis of 2019-2020 prospective data from the baseline phase of the PICU Up! pilot stepped-wedge multicenter trial (NCT03860168).

SETTING

Six PICUs in the United States.

PATIENTS

One thousand sixty-four patients who were admitted to a PICU for 3 or more days.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of 1064 patients, 74% (95% CI, 71-76%) underwent delirium screening at least once during their PICU stay. On 57% of the 8965 eligible patient days, screening was conducted. The overall prevalence of delirium was 46% across all screened days, and 64% of screened patients experienced delirium at some point during their PICU stay. Factors associated with greater adjusted odds ratio (aOR) of increased daily delirium screening included PICU stay longer than 15 days compared with 1-3 days (aOR 3.36 [95% CI, 2.62-4.30]), invasive mechanical ventilation as opposed to room air (aOR 1.67 [95% CI, 1.32-2.12]), dexmedetomidine infusions (aOR 1.23 [95% CI, 1.04-1.44]) and propofol infusions (aOR 1.55 [95% CI, 1.08-2.23]). Conversely, decreased aOR of daily delirium screening was associated with female gender (aOR 0.78 [95% CI, 0.63-0.96]), and the administration of continuous infusions of opioids (aOR 0.75 [95% CI, 0.63-0.90]) or ketamine (aOR 0.48 [95% CI, 0.29-0.79]). Neither patient age, the presence of family or physical restraints, or benzodiazepine infusions were associated with daily delirium screening rates.

CONCLUSIONS

In the 2019-2020 PICU UP! cohort, across six PICUs, delirium screening occurred on only 57% of days, despite the presence of established practices. Female gender, patients in the early stages of their PICU stay, and patients not receiving mechanical ventilation were associated with lower odds of daily delirium screening. Our results highlight the need for structured quality improvement processes to both standardize and increase the frequency of delirium screening.

Gabapentin for Delirium in Infants in the Neonatal Intensive Care Unit

OBJECTIVE

A protocol was developed for neonatal intensive care unit (NICU) delirium: Step 1, gabapentin for pain or melatonin for sleep; Step 2, add on other Step 1 agent; Step 3, antipsychotics. The purpose of this study was to describe the utility and dosing of gabapentin for NICU delirium.

METHODS

Retrospective evaluation of NICU patients from January 1, 2021-December 31, 2022 who received >1 dose of gabapentin based on the delirium protocol. Data collection included demographics, gabapentin regimen, and concomitant sedatives and analgesics. The primary objective was to identify the number of patients receiving gabapentin for Step 1 or Step 2. Secondary objectives included identifying the number of patients requiring antipsychotics (Step 3), the gabapentin regimen, comparison of Échelle de Douleur et d'Inconfort du Nouveau-né (EDIN), Cornell Assessment of Pediatric Delirium (CAPD), and Withdrawal Assessment Tool-1 (WAT-1) scores 72 hours pre- and post-gabapentin initiation, and comparison of opioids, clonidine, and melatonin 24 hours pre- and 72 hours post-gabapentin initiation. Wilcoxon signed rank tests were employed with significance defined at p < 0.05.

RESULTS

Twenty-nine patients were studied. The majority (n = 22; 75.9%) received gabapentin for Step 1; no patients required Step 3. The median initial dose was 14.4 mg/kg/day divided every 8 hours. Twelve (41.4%) required increase to a median of 16.9 mg/kg/day. A significant decrease in EDIN and WAT-1 scores was noted, but there was no change in CAPD scores or opioid, clonidine, or melatonin doses pre- versus post-gabapentin.

CONCLUSION

The majority received gabapentin at a median dose of 14 mg/kg/day as Step 1 for delirium. Gabapentin was associated with a significant decrease in pain and withdrawal scores.

Procedural sedation and analgesia in pediatric diagnostic and interventional radiology: An expert DELPHI consensus document developed by the ITALIAN scientific society of anesthesia, analgesia, resuscitation and intensive care (SIAARTI)

BACKGROUND

Children undergoing diagnostic and interventional radiology procedures often require sedation to achieve immobility and analgesia if the procedure is painful. In the past decades, leading scientific organizations have developed evidence-based guidelines for procedural sedation and analgesia in children outside of the operating room. Their recommendations are being applied to procedural sedation in radiology. However, some questions remain open regarding specific aspects contextualized to the radiology setting, such as elective prone sedation, the urgency of the procedure, when venous access or airway protection is required, and others.

AIMS

To address the unresolved issues of procedural sedation and analgesia in pediatric diagnostic and interventional radiology.

METHODS

An expert panel of pediatricians, pediatric anesthesiologists, intensivists, and neuroradiologists selected topics representative of current controversies and formulated research questions. Statements were developed by reviewing the literature for new evidence, comparing expertise and experience, and expressing opinions. Panelists' agreement with the statements was collected anonymously using the DELPHI method.

RESULTS

Twelve evidence-based or expert opinion incorporate are presented, considering risks, benefits, and applicability.

CONCLUSIONS

This consensus document, developed by a multidisciplinary panel of experts involved in the field, provides statements to improve the quality of decision-making practice in procedural sedation and analgesia in pediatric radiology.

Association of diaphragmatic dysfunction with duration of mechanical ventilation in patients in the pediatric intensive care unit: a prospective cohort study

BACKGROUND

Mechanical ventilation (MV) can cause diaphragmatic injury and ventilator induced diaphragmatic dysfunction (VIDD). Diaphragm ultrasonography (DU) is increasingly used to assess diaphragmatic anatomy, function and pathology of patients receiving MV in the pediatric intensive care unit (PICU). We report the poor contractile ability of diaphragm during ventilation of critically ill patients in our PICU and the association to prolonged length of MV and PICU stay.

METHODS

Patients who received MV within 24 h of admission to the PICU, expected to undergo continuous MV for more than 48 h and succeeded to extubate were included in the study. DU monitoring was performed daily after the initiation of MV until extubation. Diaphragm thickening fraction (DTF) measured by DU was used as an indicator of diaphragmatic contractile activity. Patients with bilateral DTF = 0% during DU assessment were allocated into the severe VIDD group (n = 26) and the rest were into non-severe VIDD group (n = 29). The association of severe VIDD with individual length of MV, hospitalization and PICU stay were analyzed.

RESULTS

With daily DU assessment, severe VIDD occurred on 2.9 ± 1.2 days after the initiation of MV, and lasted for 1.9 ± 1.7 days. Values of DTF of all patients recovered to > 10% before extubation. The severe VIDD group had a significantly longer duration (days) of MV [12.0 (8.0-19.3) vs. 5.0 (3.5-7.5), p < 0.001] and PICU stay (days) [30.5 (14.9-44.5) vs. 13.0 (7.0-24.5), p < 0.001]. The occurrence of severe VIDD, first day of severe VIDD and length of severe VIDD were significantly positively associated with the duration of MV and PICU stay. The occurrence of severe VIDD on the second and third days after initiation of MV significantly associated to longer PICU stay (days) [43.0 (9.0-70.0) vs. 13.0 (3.0-40.0), p = 0.009; 36.0 (17.0-208.0) vs. 13.0 (3.0-40.0), p = 0.005, respectively], and the length of MV (days) was significantly longer in those with severe VIDD on the third day after initiation of MV [16.5 (7.0-29.0) vs. 5.0 (2.0-22.0), p = 0.003].

CONCLUSIONS

Daily monitoring of diaphragmatic function with bedside ultrasonography after initiation of MV is necessary in critically ill patients in PICU and the influences and risk factors of severe VIDD need to be further studied. (355 words).

Closed-loop oxygen usage during invasive mechanical ventilation of pediatric patients (CLOUDIMPP): a randomized controlled cross-over study

Background

The aim of this study is the evaluation of a closed-loop oxygen control system in pediatric patients undergoing invasive mechanical ventilation (IMV).

Methods

Cross-over, multicenter, randomized, single-blind clinical trial. Patients between the ages of 1 month and 18 years who were undergoing IMV therapy for acute hypoxemic respiratory failure (AHRF) were assigned at random to either begin with a 2-hour period of closed-loop oxygen control or manual oxygen titrations. By using closed-loop oxygen control, the patients' SpO2 levels were maintained within a predetermined target range by the automated adjustment of the FiO2. During the manual oxygen titration phase of the trial, healthcare professionals at the bedside made manual changes to the FiO2, while maintaining the same target range for SpO2. Following either period, the patient transitioned to the alternative therapy. The outcomes were the percentage of time spent in predefined SpO2 ranges ±2% (primary), FiO2, total oxygen use, and the number of manual adjustments.

Findings

The median age of included 33 patients was 17 (13-55.5) months. In contrast to manual oxygen titrations, patients spent a greater proportion of time within a predefined optimal SpO2 range when the closed-loop oxygen controller was enabled (95.7% [IQR 92.1-100%] vs. 65.6% [IQR 41.6-82.5%]), mean difference 33.4% [95%-CI 24.5-42%]; P < 0.001). Median FiO2 was lower (32.1% [IQR 23.9-54.1%] vs. 40.6% [IQR 31.1-62.8%]; P < 0.001) similar to total oxygen use (19.8 L/h [IQR 4.6-64.8] vs. 39.4 L/h [IQR 16.8-79]; P < 0.001); however, median SpO2/FiO2 was higher (329.4 [IQR 180-411.1] vs. 246.7 [IQR 151.1-320.5]; P < 0.001) with closed-loop oxygen control. With closed-loop oxygen control, the median number of manual adjustments reduced (0.0 [IQR 0.0-0.0] vs. 1 [IQR 0.0-2.2]; P < 0.001).

Conclusion

Closed-loop oxygen control enhances oxygen therapy in pediatric patients undergoing IMV for AHRF, potentially leading to more efficient utilization of oxygen. This technology also decreases the necessity for manual adjustments, which could reduce the workloads of healthcare providers.

A cutting-edge new framework for the pain management in children: nanotechnology

Pain is a subjective concept which is ever-present in the medical field. Health professionals are confronted with a variety of pain types and sources, as well as the challenge of managing a patient with acute or chronic suffering. An even bigger challenge is presented in the pediatric population, which often cannot quantify pain in a numerical scale like adults. Infants and small children especially show their discomfort through behavioral and physiological indicators, leaving the health provider with the task of rating the pain. Depending on the pathophysiology of it, pain can be classified as neuropathic or nociceptive, with the first being defined by an irregular signal processing in the nervous system and the second appearing in cases of direct tissue damage or prolonged contact with a certain stimulant. The approach is generally either pharmacological or non-pharmacological and it can vary from using NSAIDs, local anesthetics, opiates to physical and psychological routes. Unfortunately, some pathologies involve either intense or chronic pain that cannot be managed with traditional methods. Recent studies have involved nanoparticles with special characteristics such as small dimension and large surface area that can facilitate carrying treatments to tissues and even offer intrinsic analgesic properties. Pediatrics has benefited significantly from the application of nanotechnology, which has enabled the development of novel strategies for drug delivery, disease diagnosis, and tissue engineering. This narrative review aims to evaluate the role of nanotechnology in current pain therapy, with emphasis on pain in children.

Psychological Health of the Adolescent Transplant Recipient

BACKGROUND

Solid organ transplant recipients experience a period of unique vulnerability during adolescence, when normative developmental changes intersect with health-related variables to influence psychological health.

METHODS

This article builds on previous reviews of psychological health in solid organ transplant recipients and proposes opportunities for clinical intervention during adolescence.

RESULTS

Transplant recipients often experience neurocognitive changes, particularly with respect to executive functions, that impact health management tasks and autonomous care. Recipients should be monitored for the development of anxiety, depression, and posttraumatic stress symptoms during adolescence, which in turn can negatively impact adherence to immunosuppression. Recent research in posttraumatic growth and resiliency factors may represent a promising avenue of intervention, leveraging normative developmental processes during this time period.

CONCLUSIONS

As pediatric transplant providers, adolescence represents a developmental period for targeted interventions to foster adjustment and adherence and promote a successful transition to adult care.

The Role of Pediatric Psychologists in Critical Care: Lessons Learned and Future Directions in Integrating Mental Health Care Into PICUs

Pediatric psychologists are essential staff in the PICU. Their role in caring for critically ill children aligns with clinical practice guidelines for the mental health care needs of this population of patients. This article highlights the role of pediatric psychology in the PICU through illustrative case examples. We discuss lessons learned and future directions for the development and provision of mental health services in PICUs. We address relevant ways for critical care providers to understand the importance of evidence-based psychological care and advocate for the inclusion of psychologists on multidisciplinary PICU teams. As the critical care field continues to focus on an improved understanding of post-intensive care syndrome in pediatrics and the psychological needs of critical care patients, it will be important to consider the vital roles of psychologists and to advocate for improved integration of mental health care in PICUs.

Impact of Prolonged Continuous Ketamine Infusions in Critically Ill Children: A Prospective Cohort Study

BACKGROUND

Ketamine has been considered as an adjunct for children who do not reach their predefined target sedation depth. However, there is limited evidence regarding the use of ketamine as a prolonged infusion (i.e., >24 hours) in the pediatric intensive care unit (PICU).

OBJECTIVE

We sought to evaluate the safety and effectiveness of continuous ketamine infusion for >24 hours in mechanically ventilated children.

METHODS

We conducted a prospective cohort study in a tertiary PICU from January 2020 to December 2022. The primary outcome was the incidence of adverse events (AEs) after ketamine initiation. The secondary outcome included assessing the median proportion of time the patient spent on the Richmond Agitation-Sedation Scale (RASS) goal after ketamine infusion. Patients were also divided into two groups based on the sedative regimen, ketamine-based or non-ketamine-based, to assess the incidence of delirium.

RESULTS

A total of 269 patients were enrolled: 73 in the ketamine group and 196 in the non-ketamine group. The median infusion rate of ketamine was 1.4 mg/kg/h. Delirium occurred in 16 (22%) patients with ketamine and 15 (7.6%) patients without ketamine (p = 0.006). After adjusting for covariates, logistic regression showed that delirium was associated with comorbidities (odds ratio [OR] 4.2), neurodevelopmental delay (OR 0.23), fentanyl use (OR 7.35), and ketamine use (OR 4.17). Thirty-one (42%) of the patients experienced at least one AE following ketamine infusion. Other AEs likely related to ketamine were hypertension (n = 4), hypersecretion (n = 14), tachycardia (n = 6), and nystagmus (n = 2). There were no significant changes in hemodynamic variables 24 h after the initiation of ketamine. Regarding the secondary outcomes, patients were at their goal RASS level for a median of 76% (range 68-80.5%) of the time in the 24 hours before ketamine initiation, compared with 84% (range 74.5-90%) of the time during the 24 h after ketamine initiation (p < 0.001). The infusion rate of ketamine did not significantly affect concomitant analgesic and sedative infusions. The ketamine group experienced a longer duration of mechanical ventilation and a longer length of stay in the PICU and hospital than the non-ketamine group.

CONCLUSION

The use of ketamine infusion in PICU patients may be associated with an increased rate of adverse events, especially delirium. High-quality studies are needed before ketamine can be broadly recommended or adopted earlier in the sedation protocol.

Delirium and Coronavirus Disease 2019: Looking Back, Moving Forward

During the coronavirus disease 2019 pandemic, crisis changes in clinical care increased rates of delirium in the intensive care unit (ICU). Deep sedation, unfamiliar environments with visitor restrictions, and such factors due to high workload and health system strain contributed to the occurrence of delirium doubling in the ICU. As the pandemic wanes, health care systems and ICU leadership must emphasize post-pandemic recovery, integrating lessons learned about delirium management, evidence-based care, and family involvement. Strategies to empower clinicians, creatively deliver care, and integrate families pave the way forward for a more holistic approach to patient care in the post-pandemic era.

Postoperative Delirium Screening Characteristics in Pediatric Intestinal, Liver, and Renal Transplant Recipients: Single-Center Retrospective Cohort Study

OBJECTIVES

To describe and compare the results of delirium screening in the immediate post-transplant PICU admission for pediatric intestinal, liver, and renal transplant recipients. We also examined associations with known and suspected risk factors for pediatric delirium (PD).

DESIGN

Retrospective analysis of a single-center cohort, 2016-2022.

SETTING

Twenty-four-bed PICU in a high-volume transplant center.

PATIENTS

All intestinal, liver, and renal transplant recipients under 23 years old admitted between July 2016 and August 2022.

MEASUREMENTS AND MAIN RESULTS

We identified 211 pediatric transplant recipients: intestinal ( n = 36), liver ( n = 78), and renal ( n = 97). Results of the Cornell Assessment for PD during the immediate post-transplant PICU admission were reviewed and patients were categorized into screen positive, screen negative, and unscreened. Corresponding data on known and suspected risk factors for PD were also collected. Data on delirium subtypes were not collected. Screens were available for 156 of 211 patients (74%) who were included in the final analysis. The prevalence of a positive screen by transplant category was: intestine 80% (24/30), liver 75% (47/63), and renal 14% (9/63). A positive screen was associated with younger age, greater duration of mechanical ventilation, and greater PICU length of stay (LOS) in bivariate analysis. In multivariable analysis, age and PICU LOS remained strongly correlated with a positive screen ( p < 0.05). Deep sedation and agitation as categorized by the State Behavioral Scale was associated with a positive screen, as was significant iatrogenic withdrawal symptoms ( p < 0.05). Most patients screened positive by post-transplant days 2 and 3 (58/80 [72%] and 64/80 [80%], respectively).

CONCLUSIONS

In our 2016 to 2022 experience, we found a high prevalence of positive PD screens in pediatric intestinal and liver transplant recipients in the immediate post-transplant PICU admission. A positive screen was associated with younger age and greater PICU LOS.

The parent perspective on paediatric delirium and an associated care bundle: A qualitative study

AIMS

To explore how parents experienced their child with delirium and how parents viewed our delirium management bundle.

DESIGN

We conducted a qualitative exploratory descriptive study using semi-structured individual or dyad interviews.

METHODS

Twelve semi-structured interviews with 16 parents of 12 critically ill children diagnosed with delirium in a paediatric intensive care unit were conducted from October 2022 to January 2023 and analysed through a reflexive thematic analysis.

FINDINGS

We generated five themes: (1) knowing that something is very wrong, (2) observing manifest changes in the child, (3) experiencing fear of long-term consequences, (4) adding insight to the bundle, and (5) family engagement.

CONCLUSION

The parents in our study were able to observe subtle and manifest changes in their child with delirium. This caused fear of lasting impact. The parents regarded most of the interventions in the delirium management bundle as relevant but needed individualization in the application. The parents requested more information regarding delirium and a higher level of parent engagement in the care of their child during delirium.

IMPACT

This paper contributes to understanding how parents might experience delirium in their critically ill child, how our delirium management bundle was received by the parents, and their suggestions for improvement. Our study deals with critically ill children with delirium, their parents, and staff working to prevent and manage paediatric delirium (PD) in the paediatric intensive care unit.

REPORTING METHOD

The consolidated criteria for reporting qualitative research guidelines were used to ensure the transparency of our reporting.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution to the research design. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL COMMUNITY?: - It increases awareness of the parent's perspective on PD in critically ill children. - It shows how PD might affect parents, causing negative emotions such as distress, frustration, and fear of permanent damage. - It shows that the parents in our study, in addition to the care bundle, requested more information on delirium and more involvement in the care of their delirious child.

Nurses' Assessment of Pain in Saudi Neonatal Intensive Care Units

BACKGROUND

Research reveals that neonatal pain management in Neonatal Intensive Care Units (NICUs) is suboptimal. There is limited research that assessed NICU nurses' pain assessment practices in Saudi Arabia.

AIM

To assess the nurses' pain assessment practices in the NICU in Saudi Arabia.

DESIGN

This study used a descriptive cross-sectional design.

SETTINGS

Research was conducted using an online survey.

PARTICIPANTS/SUBJECTS

This study was carried out on 65 NICU nurses. The participants were recruited from one governmental and one private hospital in Saudi Arabia.

METHODS

Data on pain assessment practices were collected, including the frequency of pain assessment, pain assessment scales used for preterm and term neonates, and pain assessment documentation. Data were analyzed using frequencies and percentages.

RESULTS

The majority of the participants (94%) routinely assessed pain and documented pain assessment (97%). One-third of the participants assessed pain regularly every hour (32%). The most used pain assessment scales for term neonates were the neonatal infant pain scale (40%) and the cry, required oxygen, increased vital signs, expression, and sleeplessness scale (23%). The most used pain assessment scales for preterm neonates were the neonatal infant pain scale (31%), the cry, required oxygen, increased vital signs, expression, sleeplessness scale (19%), and the premature infant pain profile (17%).

CONCLUSIONS

NICU nurses in Saudi Arabia consistently assessed for and documented pain; however, the tools chosen were sometimes suboptimal. A substantial number of NICU nurses used invalid tools to assess pain in term and preterm neonates. An interventional program is needed to enhance the use of evidence-based practice recommendations regarding neonatal pain assessment by nurses in the Neonatal Intensive Care Units in Saudi Arabia.

A nomogram for predicting postoperative delirium in pediatric patients following cardiopulmonary bypass: A prospective observational study

OBJECTIVES

To create a nomogram for early delirium detection in pediatric patients following cardiopulmonary bypass.

RESEARCH METHODOLOGY/DESIGN

This prospective, observational study was conducted in the Cardiac Intensive Care Unit at a Children's Hospital, enrolling 501 pediatric patients from February 2022 to January 2023. Perioperative data were systematically collected through the hospital information system. Postoperative delirium was assessed using the Cornell Assessment of Pediatric Delirium (CAPD). For model development, Least Absolute Shrinkage and Selection Operator (LASSO) regression was employed to identify the most relevant predictors. These selected predictors were then incorporated into a multivariable logistic regression model to construct the predictive nomogram. The performance of the model was evaluated by Harrell's concordance index, receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. External validity of the model was confirmed through the C-index and calibration plots.

RESULTS

Five independent predictors were identified: age, SpO2 levels, lymphocyte count, diuretic use, and midazolam administration, integrated into a predictive nomogram. This nomogram demonstrated strong predictive capacity (AUC 0.816, concordance index 0.815) with good model fit (Hosmer-Lemeshow test p = 0.826) and high accuracy. Decision curve analysis showed a significant net benefit, and external validation confirmed the nomogram's reliability.

CONCLUSIONS

The study successfully developed a precise and effective nomogram for identifying pediatric patients at high risk of post-cardiopulmonary bypass delirium, incorporating age, SpO2 levels, lymphocyte counts, diuretic use, and midazolam medication.

IMPLICATIONS FOR CLINICAL PRACTICE

This nomogram aids early delirium detection and prevention in critically ill children, improving clinical decisions and treatment optimization. It enables precise monitoring and tailored medication strategies, significantly contributes to reducing the incidence of delirium, thereby enhancing the overall quality of patient care.

Delirium: Where Are We Now?

Delirium has long been recognized within the adult intensive care world, but it is only within the past decade that its presence and prevalence in the context of pediatric intensive care has been studied. There is now a greater understanding of risk factors for delirium, a better selection of methods to recognize it, and treatment specifically directed to pediatric patients. An understanding of delirium is also relevant to pediatricians practicing outside of the intensive care unit, as delirium can present in other care environments, where it remains under-recognized. The purpose of this article is to review pediatric delirium by discussing its pathophysiology, the tools available to screen patients, and current prevention and management approaches.

Phenobarbital as a Sedation Strategy to Reduce Opioid and Benzodiazepine Burden in Neonatal Extracorporeal Membrane Oxygenation

OBJECTIVE

The study aims to describe our experience with the implementation of phenobarbital as a primary sedation strategy during neonatal extracorporeal membrane oxygenation (ECMO).

STUDY DESIGN

Retrospective chart review in a level IV neonatal intensive care unit between 2011 and 2021 comparing neonatal ECMO patients before and after the implementation of a sedation-analgesia (SA) protocol using scheduled phenobarbital as the primary sedative. Groups were compared for neonatal and ECMO characteristics, cumulative SA doses, and in-hospital outcomes. Comparison between groups was performed using Mann-Whitney test on continuous variables and chi-square on nominal variables.

RESULTS

Forty-two patients were included, 23 preprotocol and 19 postprotocol. Birth, pre-ECMO, and ECMO clinical characteristics were similar between groups except for a lower birth weight in the postprotocol group (p = 0.024). After standardization of phenobarbital SA protocol, there was a statistically significant reduction in median total morphine dose (31.38-17.65 mg/kg, p = 0.006) and median total midazolam dose (36.21-6.36 mg/kg, p < 0.001). There was also a reduction in median total days on morphine by 7.5 days (p = 0.026) and midazolam by 6.6 days (p = 0.003). There were no differences in ECMO duration or in-hospital outcomes between groups.

CONCLUSION

In this cohort, short-term use of phenobarbital as primary sedation strategy during neonatal ECMO was associated with reduced opioid and midazolam burden. Such reduction, however, did not affect in-hospital outcomes.

KEY POINTS

· Prolonged sedation on ECMO puts infants at risk for iatrogenic withdrawal.. · Phenobarbital is a feasible sedation strategy for ECMO.. · Phenobarbital sedation strategy may mitigate risk by decreasing opioid and midazolam burden..

R. P, Ho KHY, Sultana R, Couban R, Choong K, Lee JH. Daily Sedation Interruption vs Continuous Sedation in Pediatric Patients Receiving Mechanical Ventilation: A Systematic Review and Meta-analysis

Importance

The effectiveness of daily sedation interruption (DSI, defined as temporary interruption of sedation) has yet to be demonstrated in critically ill pediatric patients.

Objective

To compare the clinical outcomes of DSI vs continuous intravenous (IV) sedation in patients receiving invasive mechanical ventilation (MV) support in the pediatric intensive care unit (PICU).

Data Sources

A systematic search for studies was conducted using predefined keywords and Medical Subject Headings in 5 major databases (PubMed, Embase, Web of Science, CINAHL [Cumulated Index to Nursing and Allied Health Literature], and Cochrane Central Register of Controlled Trials) from database inception to October 31, 2023.

Study Selection

Retrospective and prospective observational studies, randomized clinical trials (RCTs), and systematic reviews were assessed for inclusion. Studies were eligible if they compared DSI to continuous IV sedation in patients aged 18 years or younger requiring MV in the PICU.

Data Extraction and Synthesis

Study characteristics, including the types of sedation, sedation protocols, and clinical outcomes, were extracted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline was followed. A random-effects model was used to pool results from articles for the meta-analysis.

Main Outcomes and Measures

The primary outcomes of interest were duration of MV and length of PICU stay. Secondary outcomes included total sedative dose requirement, adverse events (eg, complications associated with MV, withdrawal, and delirium), and mortality.

Results

A total of 6 RCTs with 2810 pediatric patients (1569 males [55.8%]; mean age, 26.5 [95% CI, 15.0-37.9] months) were included in the final analysis; patients had a mean PRISM (Pediatric Risk of Mortality) score of 13.68 (95% CI, 10.75-16.61). Compared with continuous IV sedation, DSI was associated with a reduction in length of PICU stay (5 studies, n = 2770; mean difference [MD], -1.45 [95% CI, -2.75 to -0.15] days; P = .03]. There was no difference in MV duration (5 studies, n = 2750; MD, -0.93 [95% CI, -1.89 to 0.04] days; P = .06), total doses of midazolam (3 studies, n = 191; MD, -1.66 [95% CI, -3.95 to 0.63] mg/kg) and morphine used (2 studies, n = 189; MD, -2.63 [95% CI, -7.01 to 1.75] mg/kg), or adverse events (risk ratio [RR], 1.03 [95% CI, 0.74-1.42]; P = .88). There was no difference in mortality between patients exposed vs not exposed to DSI (RR, 0.89 [95% CI, 0.55-1.46]; P = .65).

Conclusions and Relevance

This systematic review and meta-analysis found that use of DSI in pediatric patients was associated with reduced length of PICU stay with no increase in adverse events. Further research is needed to ascertain whether this strategy is associated with improved neurodevelopmental outcomes in PICU survivors.

Sinus Arrest Related to Dexmedetomidine Infusion in an Infant; a Case Report and Review of Current Literature

Background: Dexmedetomidine, an alpha 2 agonist, has emerged as a desirable sedative agent in the pediatric intensive care unit due to its minimal effect on respiratory status and reduction in delirium. Bradycardia and hypotension are common side effects, however there are emerging reports of more serious cardiovascular events, including sinus arrest and asystole. These case reports have been attributed to high vagal tone or underlying cardiac conduction dysfunction. Objectives: To describe the development of sinus arrest during sedation with dexmedetomidine in a patient without clinical features of high vagal tone, underlying cardiac conduction dysfunction, or intervening episodes of bradycardia. Case Presentation: An 11 month-old patient requiring sedation during mechanical ventilation for acute respiratory failure secondary to Adenovirus. To facilitate sedation, a dexmedetomidine infusion was initiated at .5 mcg/kg/hr and increased to maximum 1 mcg/kg/hr. Within 8 hours of initiating therapy, the patient had three episodes of sinus arrest. There was no intervening bradycardia between episodes and no further episodes occurred following discontinuation of dexmedetomidine. The patient did not have any clinical features associated with high vagal tone or underlying cardiac conduction dysfunction. Conclusions: As result of these findings, understanding risk factors for bradycardia, or more serious hemodynamic instability with dexmedetomidine infusions, is important to help identify high risk patients and weigh the associated risks and benefits of its administration.

Characterization of Awareness and Depth of Blockade During Neuromuscular Blockade Infusions in Critically Ill Children

OBJECTIVE

The Society of Critical Care Medicine released the first guideline for the prevention and -management of pain, agitation, neuromuscular blockade, and delirium in critically ill pediatric patients but offered conditional recommendations for sedation practices and monitoring during neuromuscular blockade. This study aimed to characterize sedation practices, patient awareness, and depth of blockade with neuromuscular blocking agent (NMBA) infusion administration in a single pediatric and cardiac intensive care unit.

METHODS

This retrospective chart review of critically ill pediatric patients queried orders for continuous infusion NMBA. Analgosedation agent(s), dose, and dose changes were assessed, along with depth of blockade monitoring via Train of Four (TOF) and awareness via Richmond Agitation and Sedation Scale (RASS).

RESULTS

Thirty-one patients were included, of which 27 (87%) had a documented sedation agent infusing at time of NMBA initiation and 17 patients (54%) were receiving analgesia. The most common agents used were rocuronium (n = 28), dexmedetomidine (n = 23), and morphine (n = 14). RASS scores were captured in all patients; however, 9 patients (29%) had recorded positive scores and 1 patient (3%) never achieved negative scores. TOF was only captured for 11 patients (35%), with majority of the scores being 0 or 4.

CONCLUSIONS

Majority of the study population did not receive recommended depth of blockade monitoring via TOF. Similarly, RASS scores were not consistent with deep sedation in half of the patients. The common use of dexmedetomidine as a single sedation agent calls into question the appropriateness of current sedation practices during NMBA continuous infusions.

Protocolized Sedation Utilizing COMFORT-B Scale versus Non-protocol-directed Sedation in Mechanically Ventilated Children - An Open-label, Randomized Controlled Trial

This study aimed to determine the effect of protocolized sedation using the COMFORT-B scale on the duration of mechanical ventilation (DMV). Eighty children with anticipated Duration of mechanical ventilation (DMV) >24 h admitted to the Pediatric intensive care unit (PICU) were randomized into one group that received protocolized sedation (PS) using the COMFORT behavioural (COMFORT-B) scale, and another group that received non-protocolized sedation (NPS). The primary outcome was the impact on the DMV. The DMV was significantly lower in PS (PS: 3.5 [3-7] vs. NPS group: 8.5 [4.25-13.75] d; p = 0.008). The cumulative dose and duration of fentanyl in the PS group was significantly lower (median [IQR]; 120 [62.88-279.12] vs. 320.4 [110.88-851.52] μg/kg; p = 0.007 and 4 [2.25-7.75] vs. 8 [4-17.5] d; p = 0.009, respectively). The authors found a decrease in DMV and sedation related adverse events (SRAE) like ventilator associated pneumonia (VAP), accidental extubation, post-extubation stridor and dose and duration of sedative agents with PS.

Multicenter Retrospective Review of Ketamine Use in Pediatric Intensive Care Units (Ketamine-PICU Study)

Objective

Describe continuous infusion (CI) ketamine practices in pediatric intensive care units (PICUs) and evaluate its effect on pain/sedation scores, exposure to analgesics/sedatives, and adverse effects (AEs).

Methods

Multicenter, retrospective, observational study in children <18 years who received CI ketamine between 2014 and 2017. Time spent in goal pain/sedation score range and daily cumulative doses of analgesics/sedatives were compared from the 24 hours (H) prior to CI ketamine to the first 24H and 25-48H of the CI. Adverse effects were collected over the first 7 days of CI ketamine.

Results

Twenty-four patients from 4 PICUs were included; median (IQR) age 7 (1-13.25) years, 54% female (n = 13), 92% intubated (n = 22), 25% on CI vasopressors (n = 6), and 33% on CI paralytics (n = 8). Ketamine indications were analgesia/sedation (n = 21, 87.5%) and status epilepticus (n = 3, 12.5%). Median starting dose was 0.5 (0.48-0.70) mg/kg/hr and continued for a median of 2.4 (1.3-4.4) days. There was a significant difference in mean proportion of time spent within goal pain score range (24H prior: 74% ± 14%, 0-24H: 85% ± 10%, and 25-48H: 72% ± 20%; p=0.014). A significant reduction in median morphine milligram equivalents (MME) was seen (24H prior: 58 (8-195) mg vs. 0-24H: 4 (0-69) mg and p=0.01), but this was not sustained (25-48H: 24 (2-246) mg and p=0.29). Common AEs were tachycardia (63%), hypotension (54%), secretions/suctioning (29%), and emergence reactions (13%).

Conclusions

Ketamine CI improved time in goal pain score range and significantly reduced MME, but this was not sustained. Larger prospective studies are needed in the pediatric population.

The knowledge, attitude and behavior on the palliative care among neonatal nurses: what can we do

BACKGROUND

Neonatal nurses should provide timely and high-quality palliative care whenever necessary. It's necessary to investigate the knowledge, attitude and behavior of palliative care among neonatal nurses, to provide references and evidences for clinical palliative care.

METHODS

Neonatal intensive care unit (NICU) nurses in a tertiary hospital of China were selected from December 1 to 16, 2022. The palliative care knowledge, attitude and behavior questionnaire was used to evaluate the current situation of palliative nursing knowledge, attitude and behavior of NICU nurses. Univariate analysis and multivariate logistic regression analysis were used to analyze the influencing factors.

RESULTS

122 nurses were finally included. The average score of knowledge in neonatal nurses was 7.68 ± 2.93, the average score of attitude was 26.24 ± 7.11, the score of behavior was 40.55 ± 8.98, the average total score was 74.03 ± 10.17. Spearman correlation indicated that score of knowledge, attitude and behavior of palliative care in neonatal nurses were correlated with the age(r = 0.541), year of work experience(r = 0.622) and professional ranks and titles(r = 0.576) (all P < 0.05). Age (OR = 1.515, 95%CI: 1.204 ~ 1.796), year of work experience (OR = 2.488, 95%CI: 2.003 ~ 2.865) and professional ranks and titles (OR = 2.801, 95%CI: 2.434 ~ 3.155) were the influencing factors of score of knowledge, attitude and behavior of palliative care (all P < 0.05).

PUBLIC CONTRIBUTION

NICU nurses have a positive attitude towards palliative care, but the practical behavior of palliative care is less and lack of relevant knowledge. Targeted training should be carried out combined with the current situation of knowledge, attitude and practice of NICU nurses to improve the palliative care ability and quality of NICU nurses.

Successful and Rapid Reduction in Neurosedative and Analgesic Medications in Complex Infants with Severe Bronchopulmonary Dysplasia After Tracheostomy Placement: Experience with 24-hour Propofol Infusions

Infants with severe bronchopulmonary dysplasia may require high doses of neurosedative medications to ensure pain control and stability following tracheostomy placement. Subsequent weaning of these medications safely and rapidly is a challenge. We describe a 24-hour propofol infusion to reduce neurosedative medications in 3 high-risk infants following tracheostomy placement.

Bringing Delirium to Light: Impact of CAM-ICU Tool to Improve Care Coordination

BACKGROUND

Delirium is a serious complication in patients in the critical care unit (CCU) that may lead to prolonged hospitalization if left undetected. The CCU at our hospital does not have a framework for determining delirium that could affect patient outcomes and discharge planning.

PRIMARY PRACTICE SETTING

CCU in a community hospital.

METHOD

A posttest-only design was used for this study. We established a framework for the early assessment of delirium, educated and trained nurses to detect delirium, collaborated with the informatics department, intensivist, nursing, respiratory therapy and worked with case management to deploy the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). We used a one-tailed independent t test to determine the impact of CAM-ICU on length of stay (LOS). Cross-tabulation and chi-square tests were used to examine the impact of CAM-ICU tool on home care utilization between the intervention and comparison groups.

RESULTS

There was a 3.12% reduction in LOS after implementing the CAM-ICU tool. Also, a reduction in home care service utilization demonstrated statistical significance ( p = .001) between the intervention group (62.5%; n = 177) and the comparison group (37.5%; n = 106).

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

Case managers are essential in improving care transitions. Case managers need to become competent in understanding the implications of the CAM-ICU tool because of their relevant role in the multidisciplinary rounds as advocates to improve care transitions across the continuum of care. Case managers need to have an understanding on how to escalate when changes in the Richmond Agitation-Sedation Scale scores occur during the multidisciplinary rounds because it can affect care coordination throughout the hospital.

CONCLUSIONS

Implementing the CAM-ICU decreased LOS, and reduced health care utilization. The early identification of patients with delirium can affect the outcomes of critically ill patients and entails multidisciplinary collaboration.

Adapting the Cornell assessment of pediatric delirium for Swedish context: translation, cultural validation and inter-rater reliability

BACKGROUND

Pediatric delirium causes prolonged hospital stays, increased costs, and distress for children and caregivers. Currently, there is no delirium screening tool available in Sweden that has been translated, culturally validated, and tested for reliability. This study aimed to translate, culturally adapt, and assess the suitability of the Cornell Assessment of Pediatric Delirium (CAPD) for implementation in Swedish healthcare settings.

METHODS

The CAPD was translated and culturally adapted to Swedish context following the ten-step process recommended by the International Society for Pharmacoeconomics and Outcomes Task Force for Translation and Cultural Adaptation. The Swedish CAPD was tested in the pediatric intensive care unit of Uppsala University Hospital, a tertiary hospital in Sweden. Inter-rater reliability was tested using intraclass correlation coefficient (ICC), with both Registered Nurses (RNs) and Assistant Nurses (ANs) conducting parallel measurements using the Swedish CAPD. A reliability score of ICC > 0.75 was considered indicative of good reliability.

RESULTS

After translation of the CAPD into Swedish, 10 RNs participated in the cultural adaptation process. Issues related to word choice, education, and instructions were addressed. Wording improvements were made to ensure accurate interpretation. Supplementary training sessions were organized to strengthen users' proficiency with the Swedish CAPD. Additional instructions were provided to enhance clarity and usability. Inter-rater reliability testing resulted in an ICC of 0.857 (95% CI: 0.708-0.930), indicating good reliability.

CONCLUSION

This study successfully translated and culturally adapted the CAPD to align with Swedish contextual parameters. The resulting Swedish CAPD demonstrated good inter-rater reliability, establishing its viability as a tool for measuring delirium among pediatric patients in Swedish pediatric intensive care units.

Palliative Care in the Intensive Care Unit: The Standard of Care

Intensive care unit-based palliative care has evolved over the past 30 years due to the efforts of clinicians, researchers, and advocates for patient-centered care. Although all critically ill patients inherently have palliative care needs, the path was not linear but rather filled with the challenges of blending the intensive care unit goals of aggressive treatment and cure with the palliative care goals of symptom management and quality of life. Today, palliative care is considered an essential component of high-quality critical care and a core competency of all critical care nurses, advanced practice nurses, and other intensive care unit clinicians. This article provides an overview of the current state of intensive care unit-based palliative care, examines how the barriers to such care have shifted, reviews primary and specialist palliative care, addresses the impact of COVID-19, and presents resources to help nurses and intensive care unit teams achieve optimal outcomes.

Comparison of invasive blood pressure monitoring vs. non-invasive blood pressure monitoring in critically ill children receiving vasoactive agents-a prospective observational study

Objective

The primary aim of this study was to compare non-invasive blood pressure (NIBP) measurement using the automated oscillometric method with invasive blood pressure (IBP) measurement using peripheral arterial line insertion in critically ill children receiving vasoactive agents.

Design

Single-centre, prospective cohort study.

Setting

Tertiary care 15 bedded Pediatric ICU in Urban Indian city.

Subjects

All critically ill children between the ages of 1 month to 16 years with shock on vasoactive medications and with IBP monitoring.

Results

Forty children with 1,072 paired BP measurements were incorporated in the final analysis. Among all normotensive children (Total number of paired measurements = 623) receiving vasoactive agents, Bland-Altman analysis revealed an acceptable agreement between Invasive mean blood pressure (MBP) and non-invasive MBP with a bias of -2.10 mmHg (SD 11.35). The 95% limits of agreement were from -24.34 to 20.14 mmHg. In children with hypotension (Total number of paired measurements = 449), Bland-Altman analysis showed disagreement between Invasive MBP and non-invasive MBP i.e., a bias of -8.44 mmHg (SD 9.62). The 95% limits of agreement were from -27.29 to 10.41 mmHg.

Conclusion

A limited agreement exists between invasive blood pressure (IBP) and non-invasive blood pressure (NIBP) measurements in critically ill children requiring vasoactive agents. This discrepancy can lead to either an underestimation or an overestimation of blood pressure. While NIBP can serve as a screening tool for hemodynamically stable children, those who are hemodynamically unstable and necessitate the initiation of vasoactive agents should undergo IBP monitoring.

Two months outcomes following delirium in the pediatric intensive care unit

The lasting consequences of delirium in children are not well characterized. This study aimed to compare the two-month outcomes in pediatric intensive care unit (PICU) survivors according to the presence of delirium. Post-hoc analysis of a single-center prospective study of mechanically ventilated (invasive ventilation or non-invasive ventilation) children followed at the CHU Sainte-Justine PICU follow-up clinic two months after PICU discharge, between October 2018 and August 2022. Delirium was defined as one or more Cornell Assessment of Pediatric Delirium (CAPD) scores ≥ 9. Primary outcome was survivors' quality of life and secondary outcomes were sleep and posttraumatic stress and anxiety and depression in parents. Multivariable linear and logistic regression models assessed the independent associations between delirium and outcomes while adjusting for age, sex, comorbidity, diagnosis, severity of illness, PICU length of stay, and invasive mechanical ventilation. Of the 179 children included over a 47 month-period, 117 (65.4%) had delirium. Children with delirium were more commonly intubated (91.5% vs. 30.7%, p < 0.001) and had higher PELOD-2 scores (10 vs. 4, p < 0.001). On multivariable analysis, delirium was associated with a decreased quality of life at 2.3 months post discharge (p = 0.03). The severity of the delirium episode (higher scores of CAPD) was associated with a higher likelihood of sleep disturbances (OR 1.13, p = 0.01) and parental anxiety (OR 1.16, p = 0.01), in addition to lower quality of life (p = 0.03).Conclusions: Two months following their PICU stay, children with delirium had a lower quality of life, suggesting a lasting effect of delirium on children and their families.

Post-Intensive Care Sequelae in Pediatrics-Results of an Early Rehabilitation Implementation Study

OBJECTIVES

To compare post-PICU discharge functioning, health-related quality of life (HRQL), and parental stress before and after the implementation of an early rehabilitation bundle.

DESIGN AND SETTING

Prospective cohort substudy within an early rehabilitation implementation program, conducted at the PICUs at McMaster Children's Hospital and London Health Sciences, London, Ontario, Canada.

INTERVENTIONS

A bundle consisting of: 1) analgesia-first sedation; 2) delirium monitoring and prevention; and 3) early mobilization. Patients with an anticipated 48-hour PICU length of stay were approached for consent to participate.

PATIENTS

Critically ill children with an anticipated 48-hour PICU length of stay were approached for consent to participate.

MEASUREMENTS AND MAIN RESULTS

Patient-/proxy-reported outcome measures were assessed at baseline, PICU discharge, and 1 and 3 months post-PICU discharge using: 1) Pediatric Evaluation of Disability Inventory Computer Adaptive Test to assess physical, social, cognitive, and responsibility/caregiver domains of functioning; 2) KIDSCREEN to assess HRQL; and 3) the Pediatric Inventory for Parents to assess caregiver stress. A total of 117 participants were enrolled. Patient demographic characteristics were similar in the pre- and post-intervention groups. Following bundle implementation, 30 of 47 respondents (63.8%) experienced functional decline and 18 of 45 (40%) experienced low HRQL at PICU discharge. Eighteen of 36 (50%) at 1 month and 14 of 38 (36.8%) at 3 months experienced either persistent functional decline and/or low HRQL; 2.8% and 2.6% at 1- and 3-month follow-up, respectively, experienced both persistent functional decline and low HRQL. There were no significant differences in the rates of persistent functional decline, low HRQL, or caregiver stress scores post-bundle compared with pre-rehabilitation bundle implementation.

CONCLUSIONS

We were unable to adequately determine the efficacy of a rehabilitation bundle on patient-centered outcomes as this substudy was not powered for these outcomes. Our results did reveal that persistent low functioning is common in PICU survivors, more common than low HRQL, while experiencing both functional decline and low HRQL was uncommon.

What's new in pediatric critical care?

Pediatric intensive care medicine is a rapidly evolving field of medicine, with recent publication of landmark papers specific for the pediatric population. Progress has been made in modes of mechanical ventilation, including noninvasive ventilation in pediatric ARDS and after extubation failure, with updated guidelines on ventilator liberation. Improved technology and advancements in hemodynamic support allow for better care of our patients with heart disease. Sepsis burden in children remains high and continued efforts are made to improve survival. A nutritional plan with a tailored approach, focusing on individualized needs, could offer benefits for our patients. Sedation practices and guidelines have been updated, focusing on minimizing delirium and facilitating early mobility. This manuscript highlights some of the most recent advances and updates.

Diagnostic accuracy of the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium and Cornell Assessment of Pediatric Delirium for detecting delirium in the pediatric intensive care unit: A systematic review and meta-analysis

OBJECTIVES

Delirium is a frequent complication of critical illness, affecting 34% of children admitted to pediatric intensive care units. The commonly used tools for detecting delirium in the pediatric intensive care unit include the Pediatric Confusion Assessment Method for the intensive care unit (ICU, pCAM-ICU), Preschool Confusion Assessment Method for the ICU (psCAM-ICU), Pediatric Anesthesia Emergence Delirium and the Cornell Assessment of Pediatric Delirium.

DATA SOURCES

We searched four electronic databases for relevant articles from inception to March 1, 2023.

STUDY SELECTION

All full-text observational studies examining the sensitivity and specificity of the four tools for screening delirium in the pediatric intensive care units were included.

DATA EXTRACTION

Two researchers independently identified articles, extracted data, and retrieved the diagnostic accuracy parameters of the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium, and Cornell Assessment of Pediatric Delirium relative to standard references. A bivariate diagnostic statistical analysis with a random-effects model was performed.

DATA SYNTHESIS

Four, five, three and seven studies on the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium, and Cornell Assessment of Pediatric Delirium, respectively, were identified. Due to the limited number of Pediatric Anesthesia Emergence Delirium articles included, no pooled diagnostic accuracy was produced. The pooled sensitivity was 0.73, 0.84, and 0.95 for the pediatric CAM-ICU, pre-school CAM-ICU, and Cornell Assessment of Pediatric Delirium, respectively, whereas the pooled specificity was 0.98, 0.90, and 0.81, respectively. The Cornell Assessment of Pediatric Delirium had greater sensitivity compared to both the pediatric CAM-ICU and pre-school CAM-ICU (both p = 0.04) and lower specificity than the pediatric CAM-ICU did (p < 0.001). Age, sample size, and mechanical ventilation use were significant moderators of the specificity of the pediatric CAM-ICU (p < 0.001, <0.001, and = 0.001, respectively).

CONCLUSIONS

Our data indicate that the Cornell Assessment of Pediatric Delirium is a more dependable instrument than the pediatric CAM-ICU and pre-school CAM-ICU for detecting pediatric intensive care delirium occurrence. More studies on the Pediatric Anesthesia Emergence Delirium are warranted.

IMPLICATIONS FOR CLINICAL PRACTICE

Healthcare providers are suggested adopting the Cornell Assessment of Pediatric Delirium into daily routine for the early detection of delirium in pediatric intensive care units.

Impact of Intravenous Methadone Dosing Schedule on Iatrogenic Withdrawal Syndrome in a Pediatric Intensive Care Unit

OBJECTIVE

To compare median Sophia Observation withdrawal Symptoms scale (SOS) scores between -intravenous methadone dosing scheduled every 6 hours or every 8 hours for iatrogenic withdrawal -syndrome (IWS).

METHODS

This single-center, retrospective chart review evaluated patients aged 4 weeks through 18 years treated with intravenous methadone for IWS. Children admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital between August 2017 and July 2021 and treated for IWS for at least 48 hours were eligible for inclusion. Methadone dosing schedules were compared, with a primary outcome of median Sophia Observation withdrawal Symptoms (SOS) score during the first 24 hours after cessation of continuous fentanyl infusion. Secondary outcomes included PICU and general pediatric unit lengths of stay, extubation failure rates, and mortality.

RESULTS

Twenty patients met inclusion criteria, with 9 in the 6-hour dosing group. There was no difference in median SOS score, extubation failure, length of stay, or mortality between the 2 groups.

CONCLUSIONS

During the first 24 hours after cessation of continuous fentanyl, there appears to be no -difference in IWS severity, as determined by bedside nurse scoring, between patients treated with -intravenous methadone every 6 hours compared with every 8 hours.

Barriers to Implementing the ICU Liberation Bundle in a Single-center Pediatric and Cardiac ICUs

Objectives: The intensive care unit (ICU) Liberation "ABCDEF" Bundle improves outcomes in critically ill adults. We aimed to identify common barriers to Pediatric ICU Liberation Bundle element implementation, to describe differences in barrier perception by ICU staff role, and to describe changes in reported barriers over time. Study Design: A 91-item survey was developed based on existing literature, iteratively revised, and tested by the PICU Liberation Committee at Seattle Children's Hospital, a tertiary free-standing academic children's hospital. Voluntary surveys were administered electronically to all ICU staff twice over 4-week periods in 2017 and 2020. Survey Respondents: 119 (2017) and 163 (2020) pediatric and cardiac ICU staff, including nurses (n = 142, 50%), respiratory therapists (RTs) (n = 46, 16%), attending and fellow physicians, hospitalists, and advanced practice providers (APPs) (n = 62, 22%), physical, occupational, and speech-language pathology therapists (n = 25, 9%), and pharmacists (n = 7, 2%). Measurements and Main Results: Respondents widely agreed that increased workload (78%-100% across roles), communication (53%-84%), and lack of RT-directed ventilator weaning (68%-88%) are barriers to implementation. Other barriers differed by role. In 2020, nurses reported liability (59%) and personal injury (68%) concerns, patient severity of illness (24%), and family discomfort with ICU liberation practices (41%) more frequently than physicians and APPs (16%, 6%, 8%, and 19%, respectively; P < .01 for all). Between 2017 and 2020, some barriers changed: RTs endorsed discomfort with early mobilization less frequently (50% vs 11%, P = .028) and nurses reported concern for patient harm less frequently (51% vs 24%, P = .004). Conclusions: Implementation efforts aimed at addressing known barriers, including educating staff on the safety of early mobility, considering respiratory therapist-directed ventilator weaning, and standardizing interdisciplinary discussion of Pediatric ICU Liberation Bundle elements, will be needed to overcome barriers and improve ICU Liberation Bundle implementation.

Knowledge, attitudes and practices of critical care unit personnel regarding pediatric palliative care: a cross-sectional study

BACKGROUND

Few studies have evaluated the perceptions of healthcare providers in China regarding pediatric palliative care, particularly in critical care units (PICUs), where many children receive palliative care. To evaluate the knowledge, attitudes and practices of PICU personnel in China regarding pediatric palliative care.

METHODS

This cross-sectional study was conducted in five cities in China (Shanghai, Suzhou, Chongqing, Chengdu and Yunnan) between November 2022 and December 2022.

RESULTS

The analysis included 204 participants (122 females), with 158 nurses and 46 physicians. The average knowledge, attitude and practice scores were 9.75 ± 2.90 points (possible range, 0-13 points), 38.30 ± 3.80 points (possible range, 12-60 points) and 35.48 ± 5.72 points (possible range, 9-45 points), respectively. Knowledge score was higher for physicians than for nurses (P < 0.001) and for personnel with previous training in pediatric palliative care (P = 0.005). According to structural equation modelling knowledge had a direct positive effect on attitude (β = 0.69 [0.28-1.10], p = 0.001), and indirect on practice (β = 0.82 [0.36-1.28], p < 0.001); attitude had significant effect on practice as well (β = 1.18 [0.81-1.56], p < 0.001).

CONCLUSIONS

There is room for improvement in the knowledge, attitudes and practices of PICU personnel in China regarding pediatric palliative care. The findings of this study may facilitate the design and implementation of targeted education/training programs to better inform physicians and nurses in China about pediatric palliative care.

Recognition and Management of Delirium in the Neonatal Intensive Care Unit: Case Series From a Single-Center Level IV Intensive Care Unit

Delirium often goes unrecognized in neonates and children because of lack of experience in evaluating behavior and cognition, insufficient awareness of the prevalence, and nondistinctive symptoms in this population. Although there are increasing reports of the presence of delirium in neonates, there are little data to guide the pharmacologic treatment in this population. In this retrospective single-center case series, we present our experience using quetiapine to treat delirium in 9 medically complex neonates. Based on an extensive literature review, expert opinion, and institutional experience, we propose an approach for monitoring and treating delirium in neonates and infants.

Prospective validation of Sophia observation withdrawal symptoms: A paediatric delirium scale in critically ill children in Denmark

BACKGROUND

Paediatric delirium (PD) is increasingly recognised as a common disorder in critically ill children with a reported prevalence ranging from 9% to 66%. We validated the PD component of the Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale in a Danish setting to provide increased awareness and reliable identification of this critical condition, thereby paving the way for improved pathways to targeted delirium care.

OBJECTIVE

The objectives of this study were to criterion validate the PD component of the SOS-PD screening tool by comparing blinded psychiatric and nurse assessments and to estimate the prevalence of delirium in critically ill children in a Danish context.

METHODS

A prospective observational study was performed on critically ill children aged between 3 m and 18 y, admitted to an intensive care unit, with a hospital stay of 48 h or more. Assessments took place on a fixed weekday over an 18-month period. To test accuracy and criterion validity, bedside nurses' SOS-PD assessments were compared to the reference standard, a diagnostic assessment performed by a child psychiatrist according to the Diagnostic and Statistical Manual-V criteria by use of the Vanderbilt Assessment of Delirium in Infants and Children.

RESULTS

We included 141 children in the study, 30 (21%) of whom were diagnosed with delirium by the child psychiatrist. The accuracy of the delirium diagnosis was 93.6% (95% confidence interval [CI]: 88.3-97.1) among the nurses' SOS-PD assessments compared to the reference standard. The SOS-PD demonstrated a high sensitivity of 83.3% (95% CI: 65.3-94.4) and a high specificity of 96.4% (95% CI: 91.0-99.0) with five false-negative and four false-positive cases.

CONCLUSION

The PD component of the SOS-PD tool has good accuracy and validity for assessments performed by nurses compared to a child psychiatrist's diagnosis in critically ill children in a Danish setting. We recommend the use of the SOS-PD instrument in clinical practice.

Pediatric patients on veno-arterial extracorporeal membrane oxygenation undergoing cardiac rehabilitation have better outcomes

Background

The importance of physical rehabilitation in optimizing outcomes in critically ill patients is recognized. However, the frequency and benefit of mobilization in pediatric patients undergoing veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) are unclear. This study evaluates a cohort of pediatric VA-ECMO patients to characterize the spectrum of mobility and evaluate associations of mobilization with clinical outcomes.

Methods

We analyzed 688 patients (8-18 years) who underwent primary ECMO runs and had mobilization data collected in the Extracorporeal Life Support Organization Registry. Demographics, pre-ECMO support, location and duration of support, and outcomes, including survival to hospital discharge, heart transplant, and ECMO-related complications, were collected. Propensity score modeling was performed with entropy weighting to compare outcomes between mobile and nonmobile patients.

Results

Of the 688 patients included, 10% achieved some degree of mobility (69/688); the majority of those exercised in bed. After propensity score matching, mobility was associated with an increased likelihood of being discharged alive (odds ratio (OR) 1.16, 95% cardiac index (CI) 1.04, 1.30) and receiving a heart transplant (OR 1.15, 95% CI 1.02, 1.29), and a lower likelihood of dying on ECMO (OR 0.90, 95% CI 0.81, 1.00). There was no association between mobility and ECMO being discontinued due to complication (OR 1.03, 95% CI 0.97, 1.10).

Conclusion

Mobilization in a pediatric VA-ECMO cohort was achieved by 1/10 patients, is associated with heart transplant and survival to hospital discharge, and is not associated with ECMO-related adverse events. Mobility in certain pediatric VA-ECMO patients is feasible and may represent an opportunity to improve outcomes.

Critical Care of the Pediatric Burn Patient

Life-saving pediatric burn care is often initiated in hospitals that are not designated as a pediatric burn center. Therefore, familiarity with critical care of pediatric burn patients is crucial for physicians working in all healthcare settings equipped to care for children. Management of airway, mechanical ventilation, preservation of ideal circulatory status, and establishment of vascular access in pediatric burn patients requires many unique considerations. This article aims to summarize important principles of critical care of children with significant burn injuries for review by physicians and surgeons working in hospitals designated as a pediatric burn center and those that stabilize these patients prior to referral.

Safety of Extended Propofol Infusions in Critically Ill Pediatric Patients

Introduction Propofol is a phenol agent with sedative and anesthetic properties that has been in use for decades, but with controversy in critically ill pediatric patients, given the concern for developing propofol-related infusion syndrome (PRIS). Our aim was to assess the risk of propofol infusions in the pediatric intensive care unit (PICU) at doses and durations greater than the described safety data and its associated covariables. Methods Retrospective cohort analysis of 173 patients receiving propofol in the PICU. Patients were categorized as receiving greater or less than 48-hour infusions. Demographic data and daily clinical variables were recorded for up to seven days post-infusion initiation or until infusion was stopped. Results In this descriptive analysis, patients' demographics were similar, but admission diagnosis was not. Both groups received high mean doses of propofol (>67 mcg/kg/min), with no cases of PRIS observed. The illness severity scores and the need for vasoactive infusion support varied between the cohorts, with higher illness scores and a higher percentage of subjects requiring vasoactive agents in the >48-hour cohort. Finally, there were no major differences in lactate levels or biochemical characteristics between the two groups. Conclusions This study provides pilot data in relation to the feasibility of propofol infusion in critically ill pediatric patients and underscores the need for a larger multicenter study to draw clinical recommendations.

Intermittent intravenous paracetamol versus continuous morphine in infants undergoing cardiothoracic surgery: a multi-center randomized controlled trial

BACKGROUND

To determine whether intermittent intravenous (IV) paracetamol as primary analgesic would significantly reduce morphine consumption in children aged 0-3 years after cardiac surgery with cardiopulmonary bypass.

METHODS

Multi-center, randomized, double-blinded, controlled trial in four level-3 Pediatric Intensive Care Units (PICU) in the Netherlands and Belgium. Inclusion period; March 2016-July 2020. Children aged 0-3 years, undergoing cardiac surgery with cardiopulmonary bypass were eligible. Patients were randomized to continuous morphine or intermittent IV paracetamol as primary analgesic after a loading dose of 100 mcg/kg morphine was administered at the end of surgery. Rescue morphine was given if numeric rating scale (NRS) pain scores exceeded predetermined cutoff values. Primary outcome was median weight-adjusted cumulative morphine dose in mcg/kg in the first 48 h postoperative. For the comparison of the primary outcome between groups, the nonparametric Van Elteren test with stratification by center was used. For comparison of the proportion of patients with one or more NRS pain scores of 4 and higher between the two groups, a non-inferiority analysis was performed using a non-inferiority margin of 20%.

RESULTS

In total, 828 were screened and finally 208 patients were included; parents of 315 patients did not give consent and 305 were excluded for various reasons. Fourteen of the enrolled 208 children were withdrawn from the study before start of study medication leaving 194 patients for final analysis. One hundred and two patients received intermittent IV paracetamol, 106 received continuous morphine. The median weight-adjusted cumulative morphine consumption in the first 48 h postoperative in the IV paracetamol group was 5 times lower (79%) than that in the morphine group (median, 145.0 (IQR, 115.0-432.5) mcg/kg vs 692.6 (IQR, 532.7-856.1) mcg/kg; P < 0.001). The rescue morphine consumption was similar between the groups (p = 0.38). Non-inferiority of IV paracetamol administration in terms of NRS pain scores was proven; difference in proportion - 3.1% (95% CI - 16.6-10.3%).

CONCLUSIONS

In children aged 0-3 years undergoing cardiac surgery, use of intermittent IV paracetamol reduces the median weight-adjusted cumulative morphine consumption in the first 48 h after surgery by 79% with equal pain relief showing equipoise for IV paracetamol as primary analgesic.

Attitudes, knowledge and practices concerning delirium among paediatric intensive care unit nurses: a multisite cross-sectional study in Sichuan, China

BACKGROUND

Delirium is an acute mental state associated with poor outcomes. The incidence of delirium is high, especially in the paediatric intensive care unit (PICU). It is important for staff, particularly nurses, to understand delirium and implement interventions to prevent it. We performed a survey with the aim of evaluating and analysing the factors influencing the knowledge, attitudes and behaviour of PICU nurses towards delirium.

METHODS

This cross-sectional descriptive study included 215 PICU nurses in 6 PICUs from five teaching hospitals in Sichuan Province, China. An online survey about the knowledge, attitudes and practices related to delirium care was conducted among PICU nurses used a self-made and validated questionnaire. The data were analysed using descriptive statistics; differences between groups were compared using t tests, ANOVA and rank-sum tests. Variables with a significance level of 0.05 in the univariate analysis were entered into the multivariable regression analysis to identify predictors.

RESULTS

Only 14.4% of the nurses had a good understanding of delirium, and 40.9% had received relevant training. The mean knowledge score was 9.01 ± 3.86, and the overall passing rate of knowledge was 49.8%. The mean attitude and behaviour scores were 40.95 ± 5.62 and 40.33 ± 8.01, respectively. Among the hospitals, different delirium assessments for children and specific training were performed, explaining approximately 10% of the variability in knowledge scores (F = 6.152), approximately 10% of the variability in attitude/belief scores (F = 5.908), and approximately 17% of the variability in practice scores (F = 10.767).

CONCLUSIONS

PICU nurses have poor knowledge of delirium, particularly regarding its clinical manifestations, influencing factors and medications used, and they have adequate attitudes and confidence and good behaviour regarding delirium in children. To better prevent delirium, we suggest that PICU departments routinely assess delirium and conduct delirium training for nurses.
