Pain related to tracheal suctioning in awake acutely and critically ill adults: A descriptive study

Optimal strategies for assessing and managing pain, agitation, and delirium in the critically ill surgical patient: What you need to know

ABSTRACT

Pain, agitation, and delirium (PAD) are primary drivers of outcome in the ICU, and expertise in managing these entities successfully is crucial to the intensivist's toolbox. In addition, there are unique aspects of surgical patients that impact assessment and management of PAD. In this review, we address the continuous spectrum of assessment, and management of critically ill surgical patients, with a focus on limiting PAD, particularly incorporating mobility as an anchor to ICU liberation. Finally, we touch on the impact of PAD in specific populations, including opioid use disorder, traumatic brain injury, pregnancy, obesity, alcohol withdrawal, and geriatric patients. The goal of the review is to provide rapid access to information regarding PAD and tools to assess and manage these important elements of critical care of surgical patients.

Investigation of pain associated with endotracheal aspiration and affecting factors in an intensive care setting: A prospective observational study

BACKGROUND

Endotracheal aspiration is a painful nociceptive procedure. There is still a gap in the literature on studies to determine the pain level and nursing interventions for aspiration.

OBJECTIVES

This study evaluated pain during endotracheal aspiration and examined the factors affecting pain.

METHODS

This prospective observational study was conducted with 105 inpatients meeting the inclusion criteria in the internal intensive care unit of a public hospital. Two hundred ten aspiration procedures were monitored for pain and other variables. ASPMN 2019 Position Statement recommendations were followed in designing the study and determining the procedure. The pain score range obtained from The Critical Care Pain Observation Tool was 0-8. A score of 2 or more is considered to indicate the presence of pain. The primary outcome measures were pain associated with endotracheal aspiration and affecting factors in this study. The generalised linear mixed model established for aspiration procedure-associated pain and affecting factors was analysed.

RESULTS

Patients' mean pain score was 1.24 ± 2.05 before, 3.07 ± 2.17 during, and 2.35 ± 1.94 after aspiration and 0.89 ± 1.40 at 15 min after aspiration. The pain rate was 26.1% before, 71% during, and 60.9% after the aspiration procedure and 18.8% after 15 min. There was a statistically significant difference between all pain scores evaluated. The difference in aspiration-related pain scores by age, respiratory diseases, sedation status, aspiration pressure, and tube diameter was statistically significant.

CONCLUSIONS

The pain score due to aspiration procedure increased significantly in intensive care unit inpatients and is an important risk factor for patient safety. More focus is needed on the causes and measures of aspiration-related pain.

Adverse effects of non-intubated airway suctioning: a clinical data-based study

AIMS AND OBJECTIVES

The purpose of this study was to investigate the adverse effects of non-intubated suctioning.

BACKGROUND

Airway hygiene aims to maintain a patent airway to ensure adequate ventilation. Nasopharyngeal, oropharyngeal or nasotracheal suctioning may be used in patients who require airway suctioning but do not have an artificial airway. However, no studies till date provide insight into the adverse effects of non-intubated airway suctioning.

DESIGN

A clinical data-based retrospective design.

METHOD

Using institutional and clinical databases of three university hospitals in 2008-2016, we conducted a study with a propensity score matching method of 3,326 hospitalised patients who had undergone suction therapy with or without a tracheotomy. Conditional logistic regression analyses were performed to investigate the link between suctioning and the probabilities of adverse effects. STROBE checklist was used to report the current study.

RESULTS

Patients who required nasopharyngeal, oropharyngeal or nasotracheal suctioning had a higher risk of gastrointestinal ulcers than tracheotomised patients (adjusted OR 1.99; 95% CI, 1.24-3.20). Patients who received non-intubated suction had a higher risk of developing pneumonia (adjusted OR 1.59; 95% CI, 1.26-2.00), and the risk of aspiration pneumonia was three times higher than tracheotomised patients (adjusted OR 3.04; 95% CI, 1.40-6.60).

CONCLUSIONS

Non-intubated patients who require suctioning for airway clearing are more susceptible to gastrointestinal ulcers, pneumonia and aspiration pneumonia. The findings would facilitate in alerting healthcare professionals to this group of patients. However, more clinical research is needed to elucidate the mechanisms of adverse effects in non-intubated patients who require suctioning.

RELEVANCE TO CLINICAL PRACTICE

The adverse effects of suctioning can easily be overlooked in debilitated patients with no intubation. Professionals must be aware of the discomfort and risks that patients may experience.

What matters most to adults with a tracheostomy in ICU and the implications for clinical practice: a qualitative systematic review and metasynthesis

PURPOSE

Tracheostomy is a common surgical procedure in ICU. Whilst often life-saving, it can have important impacts on patients. Much of the literature on tracheostomy focuses on timing and technique of insertion, risk factors and complications. More knowledge of patient experience of tracheostomy in ICU is needed to support person-centred care.

MATERIALS AND METHODS

Qualitative systematic review and metasynthesis of the literature on adult experience of tracheostomy in ICU. Comprehensive search of four bibliographic databases and grey literature. Title and abstract screening and full text eligibility was completed independently by two reviewers. Metasynthesis was achieved using thematic synthesis, supported by a conceptual framework of humanised care.

RESULTS

2971 search returns were screened on title and abstract and 127 full texts assessed for eligibility. Thirteen articles were included for analysis. Five descriptive and three analytical themes were revealed. The over-arching theme was 'To be seen and heard as a whole person'. Patients wanted to be treated as a human, and having a voice made this easier.

CONCLUSIONS

Voice restoration should be given high priority in the management of adults with a tracheostomy in ICU. Staff training should focus on both technical skills and compassionate care to improve person-centred outcomes.

Expiratory Technique versus Tracheal Suction to Obtain Good-Quality Sputum from Patients with Suspected Lower Respiratory Tract Infection: A Randomized Controlled Trial

Microbiological diagnostics of good-quality sputum samples are fundamental for infection control and targeted treatment of lower respiratory tract infections (LRTI). This study aims to compare the expiratory technique and tracheal suction on the quality of sputa from adults acutely hospitalized with suspected LRTI. We performed an open-label, randomized controlled trial. Patients were randomized to sputum sampling by tracheal suction (standard care) or the expiratory technique. The primary outcome was quality of sputum evaluated by microscopy and was analysed in the intention-to-treat population. The secondary outcomes were adverse events and patients experience. In total, 280 patients were assigned to tracheal suction (n = 141, 50.4%) or the expiratory technique (n = 139, 49.6%). Sputum samples were collected from 122 (86.5%) patients with tracheal suction and 67 (48.2%) patients with expiratory technique. Good-quality sputa were obtained more often with tracheal suction than with expiratory technique (odds ratio 1.83 [95% CI 1.05 to 3.19]; p = 0.035). There was no statistical difference in adverse events (IRR 1.21 [95% CI, 0.94 to 1.66]; p = 0.136), but patient experience was better in the expiratory technique group (p < 0.0001). In conclusion, tracheal suction should be considered a routine procedure in emergency departments for patients with suspected LRTI.

ASSESSMENT OF PROCEDURAL PAIN IN PATIENTS WITH COVID-19 IN THE INTENSIVE CARE UNIT

Aim

The purpose of the study was to assess the level of procedural pain in patients treated in the COVID-19 intensive care unit, in a tertiary university hospital.

Method

We performed the procedural pain assessment of COVID-19 patients in this study, and 162 (93.6 %) of 173 hospitalized patients assessed during this period. While pain was assessed before, during, and at the 20th minute after endotracheal aspiration, wound care, and position change, which are procedural patient practices, the pain was assessed before, during, and up to the fourth hour after prone positioning, high-flow oxygen therapy (HFOT), and the non-invasive mechanical ventilation (NIMV) procedure. The Numerical Pain Scale was used for conscious patients in pain assessment, while the Behavioral Pain Scale and the Richmond Agitation-Sedation Scale were used for unconscious patients.

Results

Patients who underwent endotracheal aspiration, wound care, and positioning had higher pain levels during procedure than other time points. Patients in the prone position with HFOT and NIMV applied had the highest pain scores at fourth hour after procedure; this increase was statistically significant (p = .000, p < .05).

Conclusions

The study found that COVID-19 patients in the ICU had pain due to procedural practices and that the level of pain during the procedures was higher because endotracheal aspiration, wound care, and positioning were all short-term procedures. Moreover, prone positioning was found to be associated with pressure-related tissue damage, and patients' pain levels increased with the increasing duration of HFOT and NIMV procedure.

Effectiveness of expiratory technique and induced sputum in obtaining good quality sputum from patients acutely hospitalized with suspected lower respiratory tract infection: a statistical analysis plan for a randomized controlled trial

Background

Targeted antimicrobial treatment is essential to avoid unnecessary use of broad-spectrum antibiotics and antimicrobial resistance. Targeted treatment relies on a precise microbiological diagnosis — in pneumonia, this poses a challenge as the usefulness of Gram stains and cultures is highly dependent on the quality of the sputum sample.

This study aims to examine adverse effects and quality of sputum samples obtained by expiratory techniques (forced expiratory technique and sputum induction) compared with tracheal suction. The hypothesis is that expiratory techniques are non-inferior to tracheal suction in obtaining samples from the lower respiratory tract. This statistical analysis plan (SAP) describes the study design, method, and data analysis of the trial to increase transparency, avoid reporting bias or data-driven analysis and increase the study’s reproducibility.

Method

The design is a pragmatic, non-inferiority, parallel-arm randomized controlled trial including 280 patients admitted with suspected lower respiratory infection to two emergency departments. Patients are randomized to a usual care group, where sputum samples are collected by tracheal suction or to an intervention group where sputum samples are collected by forced expiratory technique and sputum induction. The statistical analysis will follow an intention-to-treat protocol. This SAP is developed and submitted before the end of recruitment, database closure, and statistical analyses.

Discussion

The results of this study will provide valuable knowledge to clinical practice by comparing adverse effects and sputum sample quality associated with different sample methods.

Patient's experiences of endotracheal tubes and suction following cardiac surgery

BACKGROUND

There is a growing body of evidence addressing the patient experience of intensive care, including patient reports that the presence of an endotracheal tube is bothersome and distressing, and that endotracheal suction is moderately to extremely painful. Yet there remains little information about the patient experience of the endotracheal tube and suction in those patients receiving planned short-term mechanical ventilation.

AIMS AND OBJECTIVES

This study aimed to describe the patient experience of the endotracheal tube and suction, following mechanical ventilation in post-operative cardiac surgical patients.

DESIGN

This qualitative study used inductive thematic analysis. Participants having planned cardiac surgery, anticipated to receive less than 12-hours mechanical ventilation, were approached pre-operatively and written consent provided.

METHODS

Ten participants were recruited using purposive sampling. Semi-structured interviews were conducted between days four and six post-operatively. One researcher interviewed all participants; two researchers independently read, coded, and agreed themes.

FINDINGS

None of the participants recalled endotracheal suction, while half had no recollection of the endotracheal tube. Three themes were identified; the experience of the endotracheal tube and extubation, the experience of emerging from sedation, and participants concerns about the future. The presence of the endotracheal tube was described as bothersome, whilst breathing through the tube and extubation were described as 'weird' and 'strange' but not painful.

CONCLUSIONS

Knowledge of the patient experience can help inform nursing practice by improving pre and post-operative care planning.

RELEVANCE TO CLINICAL PRACTICE

This study adds to the body of knowledge about the patient experience of the endotracheal tube and extubation.

Pain in intensive care unit patients-A longitudinal study

Aim

To assess occurrence of pain during the first 6 days of intensive care unit (ICU) stay and evaluate associations between occurrence of pain and selected patient-related variables.

Design

A longitudinal study.

Methods

Adult ICU patients from three units were included. Patients' pain was assessed with valid pain assessment tools every 8 hr during their first 6 days in ICU. Possible associations between occurrence of pain and selected patient-related variables were modelled using multiple logistic regression.

Results

When pain was assessed regularly with pain assessment tools, 10% of patients were in pain at rest and 27% were in pain during turning. The proportions of patients who were in pain were significantly higher for patients able to self-report pain, compared with patients not able to self-report (p < .001). Several predictors were associated with being in pain. It is important to be aware of these predictors in order to improve pain management.

Airway Clearance Using Suction Devices in Prehospital Combat Casualty Care: A Systematic Review

Airway management is at the forefront for combat medics dealing with battlefield trauma. For military service members, compromised airways are the second leading cause of potentially survivable death on the battlefield, accounting for one in ten preventable combat deaths. Effective suction is a critical component of airway clearance. However, currently available devices are too heavy and bulky to be carried by combat medics and are insufficiently powered. The industry has not responded to the need, with companies continuing to produce models using 1970s technology. A literature review was completed with the assistance of a librarian. The databases searched included: Biomedical Research Database (BRD), Computer Retrieval of Information of Scientific Projects (CRISP), Federal Research in Progress (FEDRIP), Defense Technical Information Center (DTIC), Pub Med/Medline, and OVID. Additionally, a Google Scholar search was performed to identify nonstandard sources. After screening, a total of 40 articles were used. There were no randomized controlled trials or other high-quality evidence that addressed the issues; there was limited peer-reviewed literature on the use, effectiveness, adverse effects, and safety of suction for use in combat casualty care. A review of the available literature revealed no standards, either proposed, validated, or accepted, for the safety or avoidance of adverse effects for portable suction device use in combat casualty care. Similarly, there are no accepted standards to guide the safe use and anticipated adverse effects of suction for use in prehospital combat or emergency care. Nevertheless, there are meaningful data that can be extracted from the few studies available combined with non-clinical studies, narrative reviews and case reports, and expert opinions.

Continuing nursing education: use of observational pain assessment tool for diagnosis and management of pain in critically ill patients following training through a social networking app versus lectures

BACKGROUND

Nursing staff training in using observational pain assessment tools is highly important to improve the assessment of pain. The present study was conducted to examine the effect of two different training methods (lectures vs. a social networking app) on the diagnosis and management of pain in mechanically-ventilated patients.

METHODS

This quasi-experimental study was conducted on 70 nurses working in two Intensive Care Units (ICU) in Mashhad, Iran. The nurses were trained in the application of observational pain assessment tools by lectures or through a social networking app. Before and after the intervention, the nurses' performance was evaluated in both groups using a checklist based on Critical-Care Pain Observation Tool (CPOT).

RESULTS

In the pre-intervention phase, the nurses' performance scores in the domains of pain diagnosis and pain management were not significantly different between the two groups (P > 0.05). Following the intervention, the mean score of pain diagnosis was 82 ± 19 in the lecture group and 97 ± 8 in the social networking app group (P < 0.01), and the mean pain management scores were 30 ± 17 and 90 ± 18 (P < 0.01), respectively.

CONCLUSION

This study showed that learning through a social networking app led to improved diagnosis and management of pain in mechanically-ventilated patients when compared with lectures. Training through social networking applications can therefore be considered as a feasible instructional method for developing nurses' pain management skills.

Exploration of the Nociception Level (NOL™) Index for Pain Assessment during Endotracheal Suctioning in Mechanically Ventilated Patients in the Intensive Care Unit: An Observational and Feasibility Study

BACKGROUND

Many patients in the intensive care unit (ICU) suffer from pain and are non-communicative. Therefore, alternative pain measures are necessary. Although behavioral pain measures are available, physiological measures are lacking. The Nociception Level index (NOL™) provides a value from combination of multiple physiological parameters to measure pain and its use in the ICU is new.

AIM

To explore the use of a multiple physiological parameter measure for pain assessment, the NOL™ index, in mechanically ventilated patients able to self-report pain in the ICU.

METHODS

A prospective cohort study was performed. Data were collected before, during, and 15 minutes after a non-nociceptive procedure (noninvasive blood pressure using cuff inflation) and a nociceptive procedure (endotracheal suctioning). NOL index, 0 to 10 pain intensity, and Critical-Care Pain Observation Tool (CPOT) scores were also obtained. Data were analyzed using Friedman and Mann-Whitney tests. Feasibility of study procedures was described.

RESULTS

Out of 28 patients who consented, 17 remained eligible and data were analyzed for 15. Technical issues prevented obtaining a NOL signal in 2 patients. NOL values were higher during endotracheal suctioning (median = 41.6) compared with before (median = 11.2) and after the procedure (median = 11.8) and compared with cuff inflation (median = 15.1; Friedman test, p < .001). NOL values were associated with pain intensity and CPOT scores (Mann-Whitney tests, p < .05).

CONCLUSIONS

The study procedures with the NOL were found feasible; NOL values could discriminate between nociceptive and non-nociceptive procedures, and values were associated with reference pain measures. Further NOL testing is required in other ICU patient groups and procedures.

Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU

OBJECTIVE

To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU.

DESIGN

Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines' development. A general content review was completed face-to-face by all panel members in January 2017.

METHODS

Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as "strong," "conditional," or "good" practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified.

RESULTS

The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation.

CONCLUSIONS

We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

Study protocol: A randomized controlled trial assessing the avoidance of endotracheal suction in cardiac surgical patients ventilated for ≤ 12 hr

AIMS

To assess the safety and efficacy of avoiding endotracheal suction in postoperative cardiac surgical patients mechanically ventilated for ≤ 12 hr.

DESIGN

A prospective, single centre, single blind, non-inferiority, randomized controlled trial evaluating the safety and efficacy of avoiding suction in uncomplicated, postoperative, adult cardiac surgical patients mechanically ventilated for ≤ 12 hr.

METHODS

Randomization will be performed on return to intensive care (ICU) with allocation to either usual postoperative care including suction or to usual care with no suction (intervention arm). The primary outcome is the ratio of partial pressure of oxygen (PaO₂ ) to fraction of inspired oxygen (FiO₂ ) (P/F) 6 hr after extubation. Pain assessments will be performed before, during and after endotracheal suction (ETS) and the patient experience will be investigated with a brief interview the following day. Ethics approval was received in October 2015.

DISCUSSION

Endotracheal suction is performed as part of airway management but has potential complications and there is little robust evidence to guide practice. This study will add to the evidence base about the need and benefit of endotracheal suction in this patient cohort.

IMPACT

As there is currently no published evidence about the safety of avoiding endotracheal suction. This study will provide the first evidence about avoidance of endotracheal suction in patients ventilated for less than 1 day. If non-inferior, the results have the capacity to change nursing practice by avoiding a potentially unnecessary procedure, it will build on the body of knowledge about the patient experience.

Relief of Procedural Pain in Critically Ill Patients by Music Therapy: A Randomized Controlled Trial

BACKGROUND

This study aimed to determine the effectiveness of music listening for procedural pain relief using two different observational pain tools during endotracheal suctioning.

MATERIALS AND METHODS

This study was a randomized controlled trial. The sample of the study included 98 patients with mechanical ventilation support who met the selection criteria. The patients were randomly assigned to control and music therapy groups. Patients in the control group were routinely suctioned as usual. Patients in the music group received music therapy 20 min before, during, and 20 min after endotracheal suctioning. The primary outcome was the pain relief during suctioning.

RESULTS

Forty patients in each arm completed the study. Pain scores in the Critical Care Pain Observation Tool and Behavioral Pain Scale were lower in the music group than in the control group during endotracheal suctioning (group: F = 14.85, p = 0.000; F = 9.04, p = 0.000, respectively). It was also found to be a significant interaction effect between the groups and time (group × time: F = 17.35, p = 0.000; F = 18.00, p = 0.000, respectively).

CONCLUSION

The Critical Care Pain Observation Tool and Behavioral Pain Scale in the current study generally demonstrated similar pain scores during the painful procedure. Our findings support that music therapy may act as a nonpharmacological therapy to relieve procedural pain in patients on mechanical ventilation.

Pain measurement techniques: spotlight on mechanically ventilated patients

Background

Procedural pain is a frequent problem in intensive care units (ICUs). For that, pain assessment has been increasingly introduced to the ICU professional’s routine, and studies have been developed to show the relevance of measuring pain in critically ill patients.

Objective

This review aimed to describe pain measurement techniques for mechanically ventilated adult patients based on evidence and already published.

Method

Systematic literature search was performed on PubMed and Google Scholar. Keywords “pain”, “pain measurement”, “intensive care units” and “respiration, artificial” were combined to the Boolean operator AND. No language or publication year was limited in this search. The purpose and method of all papers were analyzed and only studies which described pain assessment in mechanically ventilated patients were included in this review.

Results

Objective methods were found in the literature to assess pain in mechanically ventilated adults. Behavioral scales were the most used method for pain measurement in noncommunicative patients. Vital signs were used, but the reliability of this method was questioned. Pupillometry, bispectral index and skin conductance were found and described as pain assessment methods.

Conclusion

This review showed that objective measures, as behavioral scales, are the gold standard tools to measure pain intensity in noncommunicative subjects. These data contribute to professionals’ knowledge about ICU pain measurement and emphasize its importance and consequences for adequate pain management.

Music for pain relief during bed bathing of mechanically ventilated patients: A pilot study

BACKGROUND

Pain is a universal issue and is of particular concern in mechanically ventilated patients, as they require intensive nursing care and multiple invasive procedures, while being unable to communicate verbally. The aim of this study was to assess the effect of music on pain experienced by mechanically ventilated patients during morning bed bathing.

METHODS

Of the 60 mechanically ventilated patients enrolled in this single-center pilot study between March 2013 and October 2015, the first 30 received no music and the next 30 the music intervention, during the morning bed bath. The Behavioral Pain Scale (BPS) score was determined during and at the end of the bath then 30, 60, and 120 minutes after the bath. BPS score changes over time were assessed and the proportions of bath times spent with a BPS score ≥5 and with the maximal BPS score were determined.

RESULTS

At baseline, no patient had pain (defined as a BPS score <5) and the median BPS score was 3 [IQR, 3;3] in both groups (P = 0.43). After bed bath initiation, 88% of patients experienced pain. The maximum BPS value during the bath was lower in the music group (5 [5;6.7] vs. 7 [5;7]). Proportions of total bath time spent with BPS≥5 and with the maximum BPS were significantly lower in the music group than in the control group (2.0 [0.3;4.0] vs. 10 [4.3;18.0]; P < .0001 and 1.5 [0;3.0] vs. 3.5 [2.0;6.0]; P = .005; respectively). Two hours after the end of the bath, the BPS values had returned to baseline in both groups.

CONCLUSION

In our population, music significantly decreased pain intensity and duration during the morning bed bath in mechanically ventilated patients. These results warrant further assessment in a large multicenter randomized controlled trial.

Pain among non-verbal critically Ill mechanically ventilated patients: Prevalence, correlates and predictors

PURPOSE

To investigate pain levels and factors that are predictive of pain for mechanically ventilated patients during rest and during routine nursing procedures.

MATERIAL AND METHODS

Pain levels were assessed using Behavioral Pain Scale (BPS) and physiological measures among 247 mechanically ventilated patients.

RESULTS

At rest, 33.2% of patients suffered pain, with a BPS > 3; of these, 10% presented significant pain levels (BPS ≥ 5). Variables that correspondingly predicted resting pain were age (β = -0.010, p < 0.001), sedation score (β = -0.153, p < 0.01), and method of ventilation (β = -0.281, p = 0.021). During the procedures, 90% of patients suffered pain, with a median BPS of 6 (IQR: 4-8), and 83% of patients experienced significant pain levels. Age (β = -0.022, p = 0.001), sedation score (β = -0.355, p < 0.001), receiving sedation and/or analgesia in last hour (β = 0.483, p = 0. 01), resting pain levels (β = -0.742, p < 0.001) and the type of painful procedure (β = -0.906, p < 0.001) were significant predictors of procedural pain.

CONCLUSIONS

Many mechanically ventilated patients suffer resting and procedural pain. Many variables were found to play a role. Clinicians need to consider these variables and intervene to decrease pain among patients at risk.

Validation of The Critical-care Pain Observation Tool (CPOT) for the detection of oral-pharyngeal pain in critically ill adults

OBJECTIVE

Mechanically ventilated patients experience pain at rest and during daily care procedures. Our objective was to test the reliability and validity of the Critical-Care Pain Observation Tool (CPOT) to detect oral-pharyngeal pain in intubated and tracheostomised adults during routine oral care procedures.

MATERIALS AND METHODS

Two trained research team members independently observed patients during two non-painful (rest and gentle touch) and three potentially painful (oral suctioning, tooth brushing, and swabbing with a sponge toothette) procedures. Conscious patients were asked if they experienced pain during each procedure (yes/no) and to rate their pain intensity on a 0 to 10 numeric rating scale.

RESULTS

A total of 98 patients, primarily intubated (92.9%) and male (63.3%) participated. Criterion validation was supported by patient self-report of pain during tooth brushing (AUC=.80; P<0.5) and oral suction (AUC=.72; P<0.3) but not for oral swabbing (AUC=.68; P=0.16). Discriminative validation was demonstrated for all oral care procedures compared to rest (P<.001). Intra-class correlation coefficients between raters ranged from .78 to .91 (P<.001) for total CPOT scores, indicating excellent inter-rater reliability.

CONCLUSIONS

The CPOT is reliable and valid for the detection of oral-pharyngeal pain during oral care procedures indicated as painful by critically ill adults.

Objective Nociceptive Assessment in Ventilated ICU Patients: A Feasibility Study Using Pupillometry and the Nociceptive Flexion Reflex

The concept of objective nociceptive assessment and optimal pain management have gained increasing attention. Despite the known negative short- and long-term consequences of unresolved pain or excessive analgosedation, adequate nociceptive monitoring remains challenging in non-communicative, critically ill adults. In the intensive care unit (ICU), routine nociceptive evaluation is carried out by the attending nurse using the Behavior Pain Scale (BPS) in mechanically ventilated patients. This assessment is limited by medication use (e.g., neuromuscular blocking agents) and the inherent subjective character of nociceptive evaluation by third parties. Here, we describe the use of two nociceptive reflex testing devices as tools for objective pain evaluation: the pupillary dilation reflex (PDR) and nociception flexion reflex (NFR). These measurement tools are non-invasive and well tolerated, providing clinicians and researchers with objective information regarding two different nociceptive processing pathways: (1) the pain-related autonomic reactivity and (2) the ascending component of the somatosensory system. The use of PDR and NFR measurements are currently limited to specialized pain clinics and research institutions because of impressions that these are technically demanding or time-consuming procedures, or even because of a lack of knowledge regarding their existence. By focusing on the two abovementioned nociceptive reflex assessments, this study evaluated their feasibility as a physiological pain measurement method in daily practice. Pursuing novel technologies for evaluating the analgesia level in unconscious patients may further improve individual pharmacological treatment and patient related outcome measures. Therefore, future research must include large well-designed clinical trials in a real-life environment.

Procedural pain management in patients with cancer

Pain has been identified as one of the most significant factors in patients' experience of cancer and its treatment. Pain experienced during cancer treatment procedures such as radiotherapy can be unpleasant and distressing for the patient, as well as for their family and carers. Nurses have an important role in assessing and managing any pain associated with such procedures. This article explores the procedural pain that may be experienced by patients in general, and by those with cancer specifically, and details the pharmacological and non-pharmacological strategies that nurses can use to manage this challenging complication.

How often do we perform painful and stressful procedures in the paediatric intensive care unit? A prospective observational study

BACKGROUND

Adequate analgesia and sedation is crucial in critical care. There is little knowledge on the extent of painful and stressful procedures on children admitted to a paediatric intensive care unit (PICU) and its analgesic and/or sedative management.

OBJECTIVE

The primary objective was to determine the number of painful and stressful procedures per patient per day in our PICU patients, including the numbers of attempts. A secondary objective was to map PICU nurses' perceptions of the painfulness of the included procedures.

METHODS

A prospective, single-centre observational cohort study in a tertiary PICU. All patients admitted to the PICU over a 3-month period were eligible. Readmissions, polysomnography patients, and patients without any data have been excluded. The number of painful and stressful procedures was collected daily, and use of analgesics and sedatives was assessed and recorded daily. Twenty-five randomly assigned nurses rated the painfulness of procedures based on their personal experience using a numeric rating scale from 0 to 10.

RESULTS

In a 3-month period, a total of 229 patients were included, accounting for 855 patient days. The median number of painful and stressful procedures per patient per day was 11 (interquartile range=5-23). Endotracheal suctioning was the most frequent procedure (45%), followed by oral and nasal suctioning. Arterial and lumbar puncture, peripheral IV cannula insertion, and venipuncture were scored as most painful ranging from 3 to 10. Procedural analgesia or sedation was often not used during these most painful procedures.

CONCLUSIONS

Mechanically ventilated patients undergo more than twice as many painful procedures than non-ventilated patients, as endotracheal suctioning accounts for almost half of all. Nurses regarded skin-breaking procedures most painful; however, these were rarely treated by procedural analgosedation and only covered in the minority of cases by adequate background analgosedation.

An Association Between Pain and American Association of Respiratory Care 2010 Guidelines During Tracheal Suctioning

INTRODUCTION

Tracheal suctioning is recalled by mechanically ventilated patients as the most painful procedure during their stay in the intensive care unit.

AIM

The aim of this study was to evaluate whether the implementation of American Association of Respiratory Care suction guidelines positively affects the levels of patients' pain.

MATERIALS AND METHODS

This is a prospective observational study on adult patients admitted to 2 general intensive care units. Pain levels in sedated mechanically ventilated patients were recorded before, during, and after tracheal suctioning, using the Critical Care Pain Observation Tool (CPOT).

RESULTS

Forty-seven patients were enrolled, with a mean age of 61.72 (±18.46) years. Median CPOT value was 0 (quartile 1 [Q1] [25%], 0; quartile 3 [Q3] [75%], 0; min, 0; max, 2) during the procedure. The Critical Care Pain Observation Tool reached a median value of 3, while 5 minutes after suctioning. Postprocedural CPOT median score was 0 (Q1 [25%], 0; Q3 [75%], 0; min, 0; max, 2). The median number of passes during suctioning was 1 (Q1, 1; Q3, 2). The sizes of suction catheters used in the recorded procedures were as follows: 12F in 27 cases (57%), 14F in 18 cases (38%), and 10F in 2 cases (5%). The median size of the endotracheal tube was 7.5 mm (Q1, 7.5; Q3, 8). The correct ratio between endotracheal tube diameter and suction catheter was used in 24 procedures (51%).

CONCLUSIONS

Despite the low number of patients, this study showed that the implementation of the American Association of Respiratory Care 2010 endotracheal suctioning guidelines into practice helps to reduce procedural-induced pain. Therefore, training and continuing education are important for clinical staff performing tracheal suctioning.

Challenges faced by nurses in using pain assessment scale in patients unable to communicate: a qualitative study

Background

One helpful strategy adopted for pain management in non-verbal, intubated patients is the use of a proper pain assessment scale. The purpose of the present study is to achieve a better and deeper understanding of the existing nurses' challenges in using pain assessment scales among patients unable to communicate.

Methods

This qualitative study was conducted using content analysis. Purposive sampling was used to select the participants and continued until data saturation. The participants included 20 nurses working in intensive care units. Data was collected using semi-structured interviews and analysis was done using an inductive approach.

Results

Four categories and ten sub-categories were extracted from the experiences of the nurses working in the intensive care units in terms of nursing challenges in using non-verbal pain assessment scales. The four categories included "forgotten priority", "organizational barriers", "attitudinal barriers", and "barriers to knowledge".

Conclusions

The findings of the present study have shown that various factors might influence on the use of non-verbal pain assessment scales in patients unable to communicate. Identifying these challenges for nurses can help take effective steps such as empowering nurses in the use of non-verbal pain assessment scales, relieving pain, and improving the quality of care services.

Thank you letters from patients in an intensive care unit: From the expression of gratitude to an applied ethic of care

INTRODUCTION

Patients' perception of an intensive care unit stay can lead to a better understanding of the expectations and needs of patients hospitalised in intensive care so that care for critically ill patients can be adapted and improved. Thank you letters are sources of original information which come directly and spontaneously from patients.

OBJECTIVE

The objective of this study was to analyse the thank you letters from patients who required intensive care treatment and to identify messages that could be intended for the intensive care unit team.

DESIGN

We conducted a qualitative study according to a thematic analysis. The body of research consisted of 17 letters from patients hospitalised in intensive care unit.

SETTING

The study took place in the medical-surgical intensive care unit of a French general hospital. The intensive care unit is made up of 16 resuscitation beds and four continuous monitoring beds.

FINDINGS

Two main themes emerged: (i) expression of gratitude through a description of the caregivers' behaviour (humanity and professionalism) and recognition for surviving (ii) the narrative of the intensive care unit experience.

CONCLUSION

Thank you letters give a rich insight into how the patients perceived their stay in intensive care unit. Letters from patients give direct feedback on the quality of care provided, contribute to give meaning to work and raise the question of what the core values of care should be for all concerned in the healthcare providers-patients relationship.

Symptom assessment in non-vocal or cognitively impaired ICU patients: Implications for practice and future research

BACKGROUND

Symptom assessment in critically ill patients is challenging because many cannot provide a self-report.

OBJECTIVES

To describe the state of the science on symptom communication and the assessment of selected physical symptoms in non-vocal ICU patients.

METHODS

This paper summarizes a 2014 American Thoracic Society Annual International Conference symposium presenting current evidence on symptom communication, delirium, and the assessment of common physical symptoms (i.e., dyspnea, pain, weakness, and fatigue) experienced by non-vocal ICU patients.

RESULTS

Symptom assessment begins with accurate assessment, which includes an evaluation of delirium, and assistance in symptom communication. Simple self-report measures (e.g., 0-10 numeric rating scale), observational measures (e.g., Respiratory Distress Observation Scale and Critical-Care Pain Observation Tool), or objective measures (e.g., manual muscle testing and hand dynamometry) have demonstrated utility among this population.

CONCLUSION

Optimizing symptom assessment with valid and reliable instruments with minimum patient burden is necessary to advance clinical practice and research in this field.

The Behavior Pain Assessment Tool for critically ill adults: a validation study in 28 countries

Many critically ill adults are unable to communicate their pain through self-report. The study purpose was to validate the use of the 8-item Behavior Pain Assessment Tool (BPAT) in patients hospitalized in 192 intensive care units from 28 countries. A total of 4812 procedures in 3851 patients were included in data analysis. Patients were assessed with the BPAT before and during procedures by 2 different raters (mostly nurses and physicians). Those who were able to self-report were asked to rate their pain intensity and pain distress on 0 to 10 numeric rating scales. Interrater reliability of behavioral observations was supported by moderate (0.43-0.60) to excellent (>0.60) kappa coefficients. Mixed effects multilevel logistic regression models showed that most behaviors were more likely to be present during the procedure than before and in less sedated patients, demonstrating discriminant validation of the tool use. Regarding criterion validation, moderate positive correlations were found during procedures between the mean BPAT scores and the mean pain intensity (r = 0.54) and pain distress (r = 0.49) scores (P < 0.001). Regression models showed that all behaviors were significant predictors of pain intensity and pain distress, accounting for 35% and 29% of their total variance, respectively. A BPAT cut-point score >3.5 could classify patients with or without severe levels (≥8) of pain intensity and distress with sensitivity and specificity findings ranging from 61.8% to 75.1%. The BPAT was found to be reliable and valid. Its feasibility for use in practice and the effect of its clinical implementation on patient pain and intensive care unit outcomes need further research.

[Validation of the Brazilian version of Behavioral Pain Scale in adult sedated and mechanically ventilated patients]

BACKGROUND AND OBJECTIVES

The Behavioral Pain Scale is a pain assessment tool for uncommunicative and sedated Intensive Care Unit patients. The lack of a Brazilian scale for pain assessment in adults mechanically ventilated justifies the relevance of this study that aimed to validate the Brazilian version of Behavioral Pain Scale as well as to correlate its scores with the records of physiological parameters, sedation level and severity of disease.

METHODS

Twenty-five Intensive Care Unit adult patients were included in this study. The Brazilian Behavioral Pain Scale version (previously translated and culturally adapted) and the recording of physiological parameters were performed by two investigators simultaneously during rest, during eye cleaning (non-painful stimulus) and during endotracheal suctioning (painful stimulus).

RESULTS

High values of responsiveness coefficient (coefficient=3.22) were observed. The Cronbach's alpha of total Behavioral Pain Scale score at eye cleaning and endotracheal suctioning was 0.8. The intraclass correlation coefficient of total Behavioral Pain Scale score was ≥ 0.8 at eye cleaning and endotracheal suctioning. There was a significant highest Behavioral Pain Scale score during application of painful procedure when compared with rest period (p≤0.0001). However, no correlations were observed between pain and hemodynamic parameters, sedation level, and severity of disease.

CONCLUSIONS

This pioneer validation study of Brazilian Behavioral Pain Scale exhibits satisfactory index of internal consistency, interrater reliability, responsiveness and validity. Therefore, the Brazilian Behavioral Pain Scale version was considered a valid instrument for being used in adult sedated and mechanically ventilated patients in Brazil.

A Turkish Version of the Critical-Care Pain Observation Tool: Reliability and Validity Assessment

PURPOSE

The study aim was to evaluate the validity and reliability of the Critical-Care Pain Observation Tool in critically ill patients.

DESIGN

A repeated measures design was used for the study.

METHODS

A convenience sample of 66 patients who had undergone open-heart surgery in the cardiovascular surgery intensive care unit in Ordu, Turkey, was recruited for the study. The patients were evaluated by using the Critical-Care Pain Observation Tool at rest, during a nociceptive procedure (suctioning), and 20 minutes after the procedure while they were conscious and intubated after surgery.

FINDING

The Turkish version of the Critical-Care Pain Observation Tool has shown statistically acceptable levels of validity and reliability. Inter-rater reliability was supported by moderate-to-high-weighted κ coefficients (weighted κ coefficient = 0.55 to 1.00). For concurrent validity, significant associations were found between the scores on the Critical-Care Pain Observation Tool and the Behavioral Pain Scale scores. Discriminant validity was also supported by higher scores during suctioning (a nociceptive procedure) versus non-nociceptive procedures. The internal consistency of the Critical-Care Pain Observation Tool was 0.72 during a nociceptive procedure and 0.71 during a non-nociceptive procedure.

CONCLUSIONS

The validity and reliability of the Turkish version of the Critical-Care Pain Observation Tool was determined to be acceptable for pain assessment in critical care, especially for patients who cannot communicate verbally.

Validation of the Danish version of the Critical Care Pain Observation Tool

BACKGROUND

Assessing pain in critically ill patients is a challenge even in an intensive care unit (ICU) with a no sedation protocol. The aim of this study was to validate the Danish version of the pain assessment method; Critical Care Pain Observation Tool (CPOT) in an ICU with a no sedation protocol.

METHODS

Seventy patients were included in this study. The patients were observed during a non-nociceptive procedure (wash of an arm) and a nociceptive procedure (turning). Patients were observed before, during, and 15 min after the two interventions (six assessments). Two observers participated in the data collection and CPOT scores were blinded to each other. Calculations of interrater reliability, criterion validity and discriminant validity were performed to validate the Danish version of CPOT.

RESULTS

The results indicated a good correlation between the two raters (all scores > 0.9 and P < 0.05). About 48 (68.6%) of the included patients were able to self-report pain. We found a significantly higher mean CPOT score at the nociceptive procedure than at rest or the non-nociceptive procedure (P < 0.05). No correlation was found between CPOT scores and physiological indicators. Patients self-reported pain and CPOT showed a significant correlation (P < 0.05). A CPOT score of ≥ 3 correlated with patients' self-reported pain (ROC AUC 0.83).

CONCLUSION

The Danish version of CPOT can be used to assess pain in critically ill patients, also when the ICU has a no sedation protocol. CPOT scores showed a good interrater reliability and correlates well with patient's self-reported pain.

Care-related Pain in Critically Ill Mechanically Ventilated Patients

Despite advances in pain management, critically ill patients continue to have unacceptably high rates of uncontrolled pain. Using the Behavioural Pain Scale and physiological indicators of pain, this study examines pain levels in mechanically ventilated patients prior to and during routine nursing procedures. A prospective descriptive design was used to assess and describe care-related pain associated with nociceptive procedures (repositioning, endotracheal suctioning, and vascular punctures) and non-nociceptive procedures (mouth care, eye care and dressing change). A sample of 247 mechanically ventilated Jordanian patients was recruited from intensive care units in a military hospital. The overall mean procedural pain score of 6.34 (standard deviation [SD] 2.36) was significantly higher than the mean preprocedural pain score of 3.43 (SD 0.67, t[246] = 20.82, P <0.001). The highest mean procedural pain scores were observed during repositioning (9.25, SD 1.29). Few patients received analgesics and/or sedatives in the hour prior to the procedures. The mean Ramsay Scale score was 2.49 (SD 0.95), indicating that patients were either anxious or responsive to command only. The mean physiological indicators of pain increased during repositioning and endotracheal suctioning and decreased during the rest of the procedures. Mechanically ventilated patients experience pain prior to and during routine nursing procedures. Harmless and comfort procedures are actually painful. When caring for nonverbal critically ill patients, clinicians need to consider care-related pain associated with their interventions. Relying on changes in vital signs as a primary indicator of pain can be misleading.

Comparison of Bispectral Index Monitoring With the Critical-Care Pain Observation Tool in the Pain Assessment of Intubated Adult Patients After Cardiac Surgery

Background

Detecting pain is crucial in sedated and mechanically ventilated patients, as they are unable to communicate verbally.

Objectives

This study aimed to compare Bispectral index (BIS) monitoring with the Critical-care pain observation tool (CPOT) and vital signs for pain assessment during painful procedures in intubated adult patients after cardiac surgery.

Materials and Methods

Seventy consecutive patients who underwent cardiac surgery (coronary artery bypass graft or valvular surgery) were enrolled in the study. Pain evaluations were performed early after the operation in the intubated and sedated patients by using BIS and CPOT, and also checking the vital signs. The pain assessments were done at three different times: 1) baseline (immediately before any painful procedure, including tracheal suctioning or changing the patient’s position), 2) during any painful procedure, and 3) five minutes after the procedure (recovery time).

Results

The mean values for CPOT, BIS, and mean arterial pressure (MAP) scores were significantly different at different times; they were increased during suctioning or changing position, and decreased five minutes after these procedures (CPOT: 3.98 ± 1.65 versus 1.31 ± 1.07, respectively (P ≤ 0.0001); BIS: 84.94 ± 10.52 versus 63.48 ± 12.17, respectively (P ≤ 0.0001); MAP: 92.88 ± 15.37 versus 89.77 ± 14.72, respectively (P = 0.003)). Change in heart rate (HR) was not significant over time (95.68 ± 16.78 versus 93.61 ± 16.56, respectively; P = 0.34). CPOT scores were significantly positively correlated with BIS at baseline, during painful stimulation, and at recovery time, but were not correlated with HR or MAP, except at baseline. BIS scores were significantly correlated with MAP but not with HR.

Conclusions

It appears that BIS monitoring can be used for pain assessment along with the CPOT tool in intubated patients, and it is much more sensitive than monitoring of hemodynamic changes. BIS monitoring can be used more efficiently in intubated patients under deep sedation in the ICU.

Fentanyl as pre-emptive treatment of pain associated with turning mechanically ventilated patients: a randomized controlled feasibility study

PURPOSE

To compare pain incidence and changes in pain scores with fentanyl versus placebo as pre-emptive treatment during turning and 30 min post-turning in mechanically ventilated critically ill patients.

METHODS

We performed a randomized, double-blind, parallel-group, placebo-controlled clinical trial in the intensive care unit of a university hospital. Seventy-five mechanically ventilated patients were randomized to an intervention group (fentanyl) or a control group (placebo). Patients in the intervention group received 1 µg/kg (medical patients) or 1.5 µg/kg (surgical patients) of fentanyl 10 min before turning. Pain indicators were assessed using the behavioral pain scale. Safety was assessed by determining the frequency and severity of pre-defined adverse events. Pain was evaluated at rest (T0), at turn start and end (T1 and T2) and at 5, 15 and 30 min post-turning (T3, T4 and T5).

RESULTS

The two groups had similar baseline characteristics. The area under the curve for BPS values was significantly smaller in the fentanyl group than in the control group [median and interquartile range (IQR): 132 (108-150) vs. 147 (125-180); p = 0.016, respectively]. Nineteen non-serious adverse events were recorded in 14 patients, with no significant between-group differences (23 % fentanyl group vs. 14 % control group; p = 0.381).

CONCLUSIONS

These results suggest an intravenous bolus of fentanyl of 1 µg/kg for medical patients or 1.5 µg/kg for surgical patients reduces the incidence of turning-associated pain in critically ill patients on mechanical ventilation. ClinicalTrials.gov: NCT 01950000.

Nurses' pain assessment practices with critically ill adult patients

OBJECTIVES

This study aimed to describe the perceived barriers, enablers and acute pain assessment practices of nurses caring for critically ill adult patients in a resource-limited setting.

BACKGROUND

Acute pain is a common problem among critically ill adult patients, and nurses' play a central role in its control. Very few studies have examined nurses' acute pain assessment practices in resource-limited settings.

METHODS

A descriptive and cross-sectional design was used. A total of 170 nurses working in a Ugandan hospital were enrolled. Data were collected using a questionnaire measuring various aspects of pain assessment for critically ill adult patients.

RESULTS

The majority of nurses had poor pain assessment practices. The most commonly performed pain assessment practices were documenting assessment findings, discussing pain assessment and management during nurse-to-nurse reports, and assessing for analgesics need before wound care. The main barriers to pain assessment were workload; lack of education and familiarity with assessment tools; poor documentation and communication of pain assessment priorities. The only reported enabler was physician's prescriptions for analgesia. Pain assessment practices were significantly associated with perceived workload and priority given to pain assessment.

CONCLUSION

Pain assessment practices of nurses caring for critically ill adult patients in a resource-limited setting are affected by several barriers.

IMPLICATION FOR NURSING AND HEALTH POLICY

Interventions to reduce barriers and enhance enablers of acute pain assessment are needed to improve pain management in critically ill adult patients. To be effective, the interventions have to be holistic and implemented by professional bodies and employers of nurses.

Changes in health-related quality of life in older patients one year after an intensive care unit stay

AIMS AND OBJECTIVES

This study investigates health-related quality of life in older patients, over one year following an intensive care unit stay.

BACKGROUND

Health-related quality of life is an important outcome when assessing long-term effectiveness of intensive care treatment, and to assist patients, their relatives and healthcare professionals in making treatment decisions.

DESIGN

Prospective non-randomised longitudinal study.

METHODS

The Short Form Health Survey 36 was administered 1 week after an intensive care stay (retrospective baseline), and after six months and 12 months to the study population and to an age-matched comparison group at recruitment (baseline), and after six months and 12 months. Demographic data, admission diagnosis, length of stay, severity of illness, pain, anxiety, agitation, and intratracheal suctioning, turning and intubation were recorded. Recruitment period: December 2008 to April 2011.

RESULTS

Health-related quality of life of the older patients was significantly lower than the comparison group, both before and after the intensive care unit stay, and showed great individual variability. Within group scores, however, were stable over the year. Both physical and mental health scores were lower for the older patients. Renal failure, cardiac surgery and illness severity were associated with lower physical health scores. Cardiovascular illness, intratracheal suctioning and turning were associated with lower mental health scores.

CONCLUSIONS

Health-related quality of life was lower in older patients than in the age-matched group but remained stable over one year.

RELEVANCE TO CLINICAL PRACTICE

Older patients with severe illnesses, acute renal failure or who have had cardiac surgery, need additional support after hospital discharge due to functional restrictions. Discharge planning should ensure that this support would be provided. Special attention should be given to develop and use methods to reduce distress during routine intensive care interventions such as intratracheal suctioning or turning.

The effects of music therapy in endotracheal suctioning of mechanically ventilated patients

BACKGROUND

Endotracheal suctioning has been identified as a painful procedure for critically ill patients.

AIM

To determine the effect of music therapy on pain intensity, sedation level and physiological parameters during endotracheal suctioning of mechanically ventilated patients in cardiovascular surgery intensive care unit (ICU).

DESIGN

Experimental survey.

METHODS

The study was conducted between May 2010 and June 2013 in Ordu Medical Park Hospital Cardiovascular Surgery Intensive Care Unit. The study sample consisted of 66 patients (33 experimental and 33 control) who complied with the criteria of inclusion for the study. Data was collected using the 'Patient Information Form', 'Critical-Care Pain Observation Tool', 'Ramsay Sedation Scale' and 'Form of Physiological Parameters'.

RESULTS

The mean scores of the Ramsay Sedation Scale during endotracheal aspiration were respectively 1·88 and 1·55 in the experimental and control group and the difference between the groups was statistically significant (p = 0·003). The mean score of Critical-Care Pain Observation Tool during endotracheal suctioning in the experimental group was found to be lower statistically than those of the control group (p < 0·001). There were no significant differences before, during and 20 min after suctioning between the two groups with regard to systolic blood pressure, diastolic blood pressure, heart rate and oxygen saturation (p > 0·05).

CONCLUSIONS

The results of this study implies that music therapy can be effective practice for nurses attempting to reduce patients' pain and control sedation level in patients on mechanical ventilators during endotracheal suctioning.

RELEVANCE TO CLINICAL PRACTICE

It is recommended that music therapy should be added to the routine nursing care for mechanically ventilated patients.

Generating and selecting pain indicators for brain-injured critical care patients

Current pain assessment tools for nonverbal critical care patients may not be appropriate for those with brain injury, as these patients demonstrate specific responses to pain. The aim of this study was to generate and select items that could be used to assess pain in brain-injured patients. A sequential mixed-method design was chosen with three consecutive steps: 1. Generate items with a literature review, the results of a pilot study, and interviews with 18 clinicians using the nominal group technique. 2. Evaluate content validity with 10 clinicians and four scientists, using a web-based questionnaire. 3. Describe and reduce items with the observation of 116 brain-injured patients in the intensive care unit during common painful procedures. This study took place between May 2010 and October 2011 in two tertiary hospitals in Western Switzerland. Forty-seven items were generated and reduced to 33 during the content validity process. The behaviors most frequently observed during turning were closing the eyes (58.6%), eye movements (57.8%), ventilator asynchrony (55.2%), and frowning/brow lowering (50%). Five items were observed in less than 5% of the patients during nociceptive procedure. Constant motor activity was observed more frequently at rest than during nociceptive stimulation. All physiologic items showed little variability and their reliability was low. Based on these results, the number of items was reduced to 23. This study identified items that could be specific to brain-injured patients and found that the variability of physiologic items was poorly assessed by clinicians.

A randomized controlled trial of fentanyl in the pre-emptive treatment of pain associated with turning in patients under mechanical ventilation: research protocol

AIM

To compare the effectiveness and safety of fentanyl with placebo as pre-emptive treatment for pain associated with turning in patients in intensive care units.

BACKGROUND

Turning is frequently a painful procedure in this setting. Pre-emptive administration of supplementary analgesia may help decrease this pain. However, medical literature on pre-emptive analgesia in these patients is scarce.

DESIGN

A randomized, double-blind, controlled clinical trial.

METHODS

This study will assess the benefits and risks of pre-emptive analgesia with fentanyl compared with placebo on turning-associated pain. Eighty patients will be recruited from among those older than 18 years and needing mechanical ventilation for at least 24 hours. Pain intensity will be assessed using the Behavioral Pain Scale. Primary outcome will be pain intensity between the baseline and 30 minutes after turning, measured by the area under the curve of the pain scale scores. Secondary outcomes will be the usefulness of physiological parameters and the Bispectral Index to measure pain and the safety of pre-emptive fentanyl in turning. The study protocol was approved in February 2011.

DISCUSSION

If pre-emptive fentanyl is more effective than placebo and reasonably safe, the results of the current study may change nursing attitude in managing turning in critically ill patients. As a consequence, pain may be decreased during this nursing procedure.
