Secondary infections in COVID-19: Antemortem and postmortem culture study

Background

Secondary bacterial infections during COVID-19 hospitalization have been reported in about 6-15% of patients.

Aims

To study the secondary bacterial infections that affected the COVID-19 patients during their hospitalisation and to unearth the bacteriological profile of samples obtained after their demise.

Settings and Design

This prospective study was carried out at a COVID-19 dedicated, apex tertiary care centre in North India from July 2020 to April 2021.

Methods and Materials

Samples of 268 patients were considered for the study. Nasopharyngeal swab specimen, blood, and tissue (lung) were collected from the deceased body as early as possible and processed.

Statistical Analysis

Statistical analyses were performed using STATA version 11.1 (Stata Corp., College Station, TX, USA).

Results

A total of 170 samples were received from patients before their death, which included blood, urine, respiratory samples, pus, and cerebrospinal fluid. Forty-four pathogens were isolated, which consisted of Acinetobacter baumannii (43.1%), Klebsiella pneumoniae (36.3%), Escherichia coli (11.3%), and Pseudomonas aeruginosa (4.5%), Enterococcus faecium (4.5%). Two hundred fifty-eight samples were collected from the deceased bodies wherein the nasopharyngeal sample was highest, followed by tissue and blood. A total of 43 pathogens were isolated among them which included A. baumannii (44.1%), followed by K. pneumoniae (25.5%), E. coli (20.9%), P. aeruginosa (6.97%) and Enterobacter cloacae (2.3%). All these isolates were highly resistant to antimicrobials.

Conclusions

In our study, bacterial profiles in antemortem and postmortem samples were found to be similar, suggesting that resistant pathogens may be the cause of mortality in COVID-19 infected hospitalised patients.

Incidence of COVID-19-Associated Mucormycosis in COVID-19 Patients after Discharge from the COVID-19 Hospital

Background

There are studies available on the prevalence of coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) in hospitalized patients but not on the incidence of CAM in post-discharge patients. The aim of our study was to find the incidence of CAM in the patients discharged from a COVID hospital.

Material and Methods

Adult patients with COVID discharged between March 1, 2021 and June 30, 2021 were contacted and enquired about sign and symptoms of CAM. Data of all included patients were collected from electronic records.

Results

A total of 850 patients responded, among which 59.4% were males, 66.4% patients had co-morbidities, and 24.2% had diabetes mellitus. Around 73% of patients had moderate to severe disease and were given steroids; however, only two patients developed CAM post discharge.

Conclusion

The incidence of CAM post discharge was low in our study, which could be attributed to protocolized therapy and intensive monitoring.

No Major Age Shift During the Second Wave of COVID-19: A Mortality Analysis at a Tertiary-Level Hospital

OBJECTIVE

The second wave of coronavirus epidemic affected India severely. We reviewed the in-hospital deaths during the second wave at a dedicated COVID hospital to better understand the clinical characteristics of patients who died during this period.

METHODS

Clinical charts of all patients who were admitted and died in-hospital due to COVID-19 between 1 April 2021 and 15 May 2021 were reviewed and clinical data were analysed.

RESULTS

The total number of patients admitted to hospital and the intensive care unit was 1438 and 306, respectively. The in-hospital and intensive care unit mortality was 9.3% (134 out of 1438 patients) and 37.6% (115 out of 306 patients), respectively. Septic shock with multiorgan failure was the cause of death in 56.6% of the deceased patients (n = 73) and acute respiratory distress syndrome in 35.3% (n = 47) patients. Of the deceased, 1 patient was less than 12 years old, 56.8% were between 13 and 64 years of age and 42.5% were geriatric, that is, 65 years of age or older. There were no comorbidities in 35.1% of the deceased patients. The cause of death did not vary with the age group.

CONCLUSION

The in-hospital and intensive care unit mortality during the second wave was 9.3% and 37.6%, respectively. There was no major age group shift in the second wave as compared to the first wave. However, a significant number of patients (35.1%) did not have any comorbidity. Septic shock with multiorgan failure was the most common cause of death followed by acute respiratory distress syndrome.

Clinical Course and Outcome of Critically Ill Obese Patients with COVID-19 Admitted in Intensive Care Unit of a Single Center: Our Experience and Review

Introduction

Obesity has been considered as one of the independent risk factors for a severe form of coronavirus disease-2019 (COVID-19) and relationship between obesity, critical illness, and infection is still poorly understood. We herein discuss clinical course and outcome of critically ill obese patients with COVID-19 admitted to critical care unit.

Materials and methods

We retrospectively analyzed data of critically ill obese patients hospitalized with COVID-19 over a span of 6 months. Management was guided according to the institutional protocol. Collected data included demographic parameters (age, sex, comorbidities, and body mass index (BMI)), complications, inflammatory markers (interleukin (IL)-6, Ferritin), length of mechanical ventilation, length of intensive care unit (ICU) stay, and inhospital death.

Results

There was no appreciable difference in terms of demographics, inflammatory markers, predictors of mortality scores, and comorbidity indices between the survivors and nonsurvivors. Among outcome analysis, there was a statistically significant difference between ventilator days between survivors and nonsurvivors (p = 0.003^**).

Conclusion

Obesity itself is a significant risk factor for severe COVID-19 infection; however, if efficiently managed and in a protocol-determined manner, it can have a favorable outcome.

Integrated ultrasound protocol in predicting weaning success and extubation failure: a prospective observational study

BACKGROUND

Difficulty in weaning from mechanical ventilation is encountered in appro-ximately 20% of patients in the intensive care unit. We assessed the utility of a combined lung, diaphragmatic, and cardiac ultrasound protocol to predict extubation failure.

MATERIAL

All patients extubated following a successful spontaneous breathing trial (SBT) were included in the study. Lung ultrasonography score (LUS), diaphragmatic thickness fraction (DTF), changes in velocity time integral (VTI) to passive leg raise at the beginning of SBT, and change in LUS following SBT were recorded.

RESULTS

A total of 60 patients who underwent successful SBT were included in the study. Twenty-seven patients required either non-invasive or invasive mechanical ventilation during the next 48 hours and were classified as weaning failure (Group F). The remaining 33 patients were designated as weaning success (Group S). Compared to group S, patients in Group F had significantly longer ICU length of stay (6.96 ± 4.30 days vs. 11.66 ± 3.85 days, P < 0.001), higher LUS change during SBT (1 [0-2] vs. 2 [1-4], P < 0.001), lower DTF (30.87 ± 5.32 vs. 27.88 ± 6.24, P = 0.04), and showed lower VTI increment to PLR (13.63 ± 3.44 vs. 9.11 ± 4.59, P < 0.001). Using a binary logistic regression model, DTF < 26% (odds ratio 6.20, 95% CI: 1.06-36.04) and VTI change to PLR < 10.2% (odds ratio 6.16, 95% CI: 1.14-33.13) were found to be significant predictors of weaning failure (P < 0.05). The AUROC for VTI and DTF for predicting weaning failure were 0.79 and 0.64, respectively.

CONCLUSIONS

An integrated ultrasound protocol using a combination of lung, diaphragm, and cardiac sonography was a reliable predictor of weaning failure.

Neutrophil-to-lymphocyte Ratio and Platelet-to-lymphocyte Ratio as Markers for Predicting the Severity in COVID-19 Patients: A Prospective Observational Study

Background: Coronavirus disease-2019 (COVID-19) pandemic has shown unpredictable course in individual patients. Few patients develop severe disease with progression after admission to a healthcare facility. Multiple parameters have been investigated to identify a marker to predict disease progression. Neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte (PLR) ratio has shown some promise. The current investigation explores the role of NLR and PLR to predict the disease progression.

Materials and methods: After obtaining ethics committee approval, 608 patients were screened for inclusion in the prospective observational study, and 201 patients were included in the final analysis. The NLR and PLR were derived from routinely obtained complete blood count analysis. The patients were followed to determine the development of severity of the disease during the course. The NLR and PLR were analyzed in both univariate and multivariable models to assess the association and prediction.

Results: In nonsevere (NS) group, the mean age of patients was 50.9 ± 16.3 years, and 66 (61.2%) were male, while in severe group (S), the mean age of patients was 53.7 ± 16.4 years, and 65 (69.89%) were male. NLR at day 1 and day 3 was significantly lower in survivors as compared to nonsurvivors, while the relation of PLR in both the groups was not statistically significant. The NLR is better in predicting the severity of disease as well as mortality than PLR.

Conclusion: The NLR calculated at the time of admission has high predictive value for disease deterioration and adverse clinical outcome.

COVID-19 Illness in a Patient With Anti-Glomerular Basement Membrane Disease: A Clinical Dilemma

Anti-glomerular basement membrane (anti-GBM) disease is a rare autoimmune disease affecting the kidneys and lungs. COVID-19 infection in a patient with pre-existing anti-GBM disease presents a unique set of clinical challenges. The formulation of a judicious treatment plan balancing both disease processes is tricky, especially with regard to anticoagulation. We present the case of a young patient with anti-GBM disease who acquired COVID-19 infection and eventually succumbed to his illness.

Outcome of Conservative Therapy in Coronavirus disease-2019 Patients Presenting With Gastrointestinal Bleeding

BACKGROUND/OBJECTIVE

There is a paucity of data on the management of gastrointestinal (GI) bleeding in patients with Coronavirus disease -2019 (COVID-19) amid concerns about the risk of transmission during endoscopic procedures. We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19.

METHODS

In this retrospective analysis, 24 of 1342 (1.8%) patients with COVID-19, presenting with GI bleeding from 22nd April to 22nd July 2020, were included.

RESULTS

The mean age of patients was 45.8 ± 12.7 years; 17 (70.8%) were males; upper GI (UGI) bleeding: lower GI (LGI) 23:1. Twenty-two (91.6%) patients had evidence of cirrhosis- 21 presented with UGI bleeding while one had bleeding from hemorrhoids. Two patients without cirrhosis were presumed to have non-variceal bleeding. The medical therapy for UGI bleeding included vasoconstrictors-somatostatin in 17 (73.9%) and terlipressin in 4 (17.4%) patients. All patients with UGI bleeding received proton pump inhibitors and antibiotics. Packed red blood cells (PRBCs), fresh frozen plasma (FFPs) and platelets were transfused in 14 (60.9%), 3 (13.0%) and 3 (13.0%), respectively. The median PRBCs transfused was 1 (0-3) unit(s). The initial control of UGI bleeding was achieved in all 23 patients and none required an emergency endoscopy. At 5-day follow-up, none rebled or died. Two patients later rebled, one had intermittent bleed due to gastric antral vascular ectasia, while another had rebleed 19 days after discharge. Three (12.5%) cirrhosis patients succumbed to acute hypoxemic respiratory failure during hospital stay.

CONCLUSION

Conservative management strategies including pharmacotherapy, restrictive transfusion strategy, and close hemodynamic monitoring can successfully manage GI bleeding in COVID-19 patients and reduce need for urgent endoscopy. The decision for proceeding with endoscopy should be taken by a multidisciplinary team after consideration of the patient's condition, response to treatment, resources and the risks involved, on a case to case basis.

Clinicoepidemiological Features and Mortality Analysis of Deceased Patients with COVID-19 in a Tertiary Care Center

Background and objective

A large number of studies describing the clinicoepidemiological features of coronavirus disease-2019 (COVID-19) patients are available but very few studies have documented similar features of the deceased. This study was aimed to describe the clinicoepidemiological features and the causes of mortality of COVID-19 deceased patients admitted in a dedicated COVID center in India.

Methodology

This was a retrospective study done in adult deceased patients admitted in COVID ICU from April 4 to July 24, 2020. The clinical features, comorbidities, complications, and causes of mortality in these patients were analyzed. Pediatric deceased were analyzed separately.

Results

A total of 654 adult patients were admitted in the ICU during the study period and ICU mortality was 37.7% (247/654). Among the adult deceased, 65.9% were males with a median age of 56 years [interquartile range (IQR), 41.5-65] and 94.74% had one or more comorbidities, most common being hypertension (43.3%), diabetes mellitus (34.8%), and chronic kidney disease (20.6%). The most common presenting features in these deceased were fever (75.7%), cough (68.8%), and shortness of breath (67.6%). The mean initial sequential organ failure assessment score was 9.3 ± 4.7 and 24.2% were already intubated at the time of admission. The median duration of hospital stay was 6 days (IQR, 3-11). The most common cause of death was sepsis with multi-organ failure (55.1%) followed by severe acute respiratory distress syndrome (ARDS) (25.5%). All pediatric deceased had comorbid conditions and the most common cause of death in this group was severe ARDS.

Conclusion

In this cohort of adult deceased, most were young males with age less than 65 years with one or more comorbidities, hypertension being the most common. Only 5% of the deceased had no comorbidities. Sepsis with multi-organ dysfunction syndrome was the most common cause of death.

Are the steroids a blanket solution for COVID-19? A systematic review and meta-analysis

Steroids may play a critical role in the current pandemic of coronavirus disease-2019 (COVID-19), given the dearth of specific therapeutic options. This review was conducted to evaluate the impact of glucocorticoid therapy in patients with COVID-19 based on the publications reported to date. A comprehensive screening was conducted using electronic databases up to August 19, 2020. The randomized controlled trials (RCTs) and cohort studies evaluating the effectiveness and safety of steroids in patients with COVID-19 are included for the meta-analyses. Our search retrieved twelve studies, including two RCTs and 10 cohort studies, with a total of 15,754 patients. In patients with COVID-19, the use of systemic glucocorticoid neither reduce mortality (odds ratio [OR] = 1.94, 95% confidence interval [CI]: 1.11-3.4, I²  = 96%), nor the duration of hospital stay (mean difference [MD] = 1.18 days, 95% CI: -1.28 to 3.64, I²  = 93%) and period of viral shedding (MD = 1.42 days, 95% CI: -0.52 to 3.37, I²  = 0%). Systemic steroid therapy may not be effective for reducing mortality, duration of hospitalization, and period of viral shedding. Studies are mostly heterogeneous. Further RCTs are required.

Convalescent plasma is a clutch at straws in COVID-19 management! A systematic review and meta-analysis

In the absence of definitive therapy for coronavirus disease (COVID‐19), convalescent plasma therapy (CPT) may be a critical therapeutic option. This review was conducted to evaluate the impact of CPT in COVID‐19 patients based on the publications reported to date. A robust screening of electronic databases was conducted up to 10th July 2020. Randomized controlled trials (RCTs), cohort studies, and case series with a control group evaluating the effectiveness and safety of CPT in patients with COVID‐19 are included for the meta‐analyses. Our search retrieved seven studies, including two RCTs and five cohort studies, with a total of 5444 patients. In patients with COVID‐19, the use of CPT reduces mortality (odd's ratio [OR] 0.44; 95% CI, 0.25‐0.77), increases viral clearance (OR, 11.29; 95% CI, 4.9‐25.9) and improves clinically (OR, 2.06; 95% CI, 0.8 to 4.9). However, the evidence is of low quality (mortality reduction, and viral clearance), and very low quality (clinical improvement). CPT may be beneficial for reducing mortality, viral shedding and improving clinical conditions in COVID‐19 patients. However, further randomized control trials (RCT) are required to substantiate the safety margin, initiation, optimal dosage, titre and duration of CPT.

Prehospital notification of injured patients presenting to a trauma centre in India: a prospective cohort study

OBJECTIVES

To assess the effect of a mobile phone application for prehospital notification on resuscitation and patient outcomes.

DESIGN

Longitudinal prospective cohort study with preintervention and postintervention cohorts.

SETTING

Major trauma centre in India.

PARTICIPANTS

Injured patients being transported by ambulance and allocated to red (highest) and yellow (medium) triage categories.

INTERVENTION

A prehospital notification application for use by ambulance and emergency clinicians to notify emergency departments (EDs) of an impending arrival of a patient requiring advanced lifesaving care.

MAIN OUTCOME MEASURES

The primary outcome was the proportion of eligible patients arriving at the hospital for which prehospital notification occurred. Secondary outcomes were the availability of a trauma cubicle, presence of a trauma team on patient arrival, time to first chest X-ray, and ED and in-hospital mortality.

RESULTS

Data from January 2017 to January 2018 were collected with 208 patients in the preintervention and 263 patients in the postintervention period. The proportion of patients arriving after prehospital notification improved from 0% to 11% (p<0.001). After the intervention, more patients were managed with a trauma call-out (relative risk (RR) 1.30; 95% CI: 1.10 to 1.52); a trauma bay was ready for more patients (RR 1.47; 95% CI: 1.05 to 2.05) and a trauma team leader present for more patients (RR 1.50; 95% CI: 1.07 to 2.10). There was no difference in time to the initial chest X-ray (p=0.45). There was no association with mortality at hospital discharge (RR 0.94; 95% CI: 0.72 to 1.23), but the intervention was associated with significantly less risk of patients dying in the ED (RR 0.11; 95% CI: 0.03 to 0.39).

CONCLUSIONS

The prehospital notification application for severely injured patients had limited uptake but implementation was associated with improved trauma reception and reduction in early deaths. Quality improvement efforts with ongoing data collection using the trauma registry are indicated to drive improvements in trauma outcomes in India.

Primary vs delayed primary closure in patients undergoing lower limb amputation following trauma: A randomised control study

Lower limb crush injury is a major source of mortality and morbidity in trauma patients. Complications, especially surgical site infections (SSIs) are a major source of financial burden to the institute and to the patient as it delays rehabilitation. As such, every possible attempt should be made to reduce any complications. We, thus, aimed to compare the outcomes in early vs delayed closure of lower extremity stumps in cases of lower limb crush injury requiring amputation, so as to achieve best possible outcome. A randomised controlled study was conducted in the Division of Trauma Surgery & Critical Care at Jai Prakash Narayan Apex Trauma Centre, All India Institute of Medical Sciences, New Delhi from 1 September 2018 to 30 June 2019 and included patients undergoing lower limb amputation below hip joint. Patients were randomised in two groups, in one group amputation stump was closed primarily, while in the second group delayed primary closure of stump was performed. We compared rate of SSI, length of hospital stay, and number of surgeries in both the groups. Fifty-six patients with 63 amputation stumps were recruited in the study. Mean age of patients in the study was 34 years, of which about 95% patients were males. The most common mechanism of injury was road traffic injury in 66% of patients. Mean injury severity score was 12.28 and four patients had diabetes preoperatively. Total 63 extremities were randomised with 30 cases in group I and 33 cases in group II as per computer-generated random number. Above knee amputations was commonest (57.14%) followed by below knee amputations (33.3%). Two patients died in the current study. In group I, In-hospital infection was detected in 7 cases (23.3%) and in group II 9 cases (27.3%) had SSI during hospital admission (P > .05). Mean hospital stay in group I was 10.32 ± 7.68 days and in group II was 11 ± 8.17 days (P > .05). Road traffic injuries and train-associated injuries are a major cause of lower limb crush injuries, leading to limb loss. Delayed primary closure of such wounds requires extra number of surgical interventions than primary closure. There is no difference in extra number of surgical interventions required in both the groups. Thus, primary closure can be safely performed in patients undergoing lower limb amputations following trauma, provided that a good lavage and wound debridement is performed.

A checklist for trauma quality improvement meetings: A process improvement study

BACKGROUND

Each year approximately five million people die from injuries. In countries where systems of trauma care have been introduced, death and disability have decreased. A major component of developed trauma systems is a trauma quality improvement (TQI) program and trauma quality improvement meeting (TQIM). Effective TQIMs improve trauma care by identifying and fixing problems. But globally, TQIMs are absent or unstructured in most hospitals providing trauma care. The aim of this study was to implement and evaluate a checklist for a structured TQIM.

METHODS

This project was conducted as a prospective before-and-after study in four major trauma centres in India. The intervention was the introduction of a structured TQIM using a checklist, introduced with a workshop. This workshop was based on the World Health Organization (WHO) TQI Programs short course and resources, plus the developed TQIM checklist. Pre- and post-intervention data collection occurred at all meetings in which cases of trauma death were discussed. The primary outcome was TQIM Checklist compliance, defined by the discussion of, and agreement upon each of the following: preventability of death, identification of opportunities to improve care and corrective actions and a plan for closing the loop.

RESULTS

There were 34 meetings in each phase, with 99 cases brought to the pre-intervention phase and 125 cases brought to the post-intervention phase. There was an increase in the proportion of cases brought to the meeting for which preventability of death was discussed (from 94% to 100%, p = 0.007) and agreed (from 7 to 19%, OR 3.7; 95% CI:1.4-9.4, p = 0.004) and for which a plan for closing the loop was discussed (from 2% to 18%, OR 10.9; 95% CI:2.5-47.6, p < 0.001) and agreed (from 2% to 18%, OR 10.9; 95% CI:2.5-47.6, p < 0.001).

CONCLUSION

This study developed, implemented and evaluated a TQIM Checklist for improving TQIM processes. The introduction of a TQIM Checklist, with training, into four Indian trauma centres, led to more structured TQIMs, including increased discussion and agreement on preventability of death and plans for loop closure. A TQIM Checklist should be considered for all centres managing trauma patients.

Recruitment maneuver does not provide any mortality benefit over lung protective strategy ventilation in adult patients with acute respiratory distress syndrome: a meta-analysis and systematic review of the randomized controlled trials

Background

Clinical benefits of recruitment maneuver in ARDS patients are controversial. A number of previous studies showed possible benefits; a large recent study reported that recruitment maneuver and PEEP titration may even be harmful. This meta-analysis was designed to compare the clinical utility of recruitment maneuver with low tidal volume ventilation in adult patients with ARDS.

Methods

Randomized controlled trials comparing recruitment maneuver and lung protective ventilation strategy with lung protective strategy ventilation protocol alone in adult patients with ARDS has been included in this meta-analysis. PubMed and Cochrane Central Register of Controlled Trials were searched from inception to 10 November 2017 to identify potentially eligible trials. Pooled risk ratio (RR) and standardized mean difference (SMD) were calculated for binary and continuous variables respectively.

Results

Data of 2480 patients from 7 randomized controlled trials have been included in this meta-analysis and systemic review. Reported mortality at the longest available follow-up [RR (95% CI) 0.93 (0.80, 1.08); p = 0.33], ICU mortality [RR (95% CI) 0.91 (0.76, 1.10); p = 0.33] and in-hospital mortality [RR (95% CI) 0.95 (0.83, 1.08); p = 0.45] were similar between recruitment maneuver group and standard lung protective ventilation group. Duration of hospital stay [SMD (95% CI) 0.00 (− 0.09, 0.10); p = 0.92] and duration of ICU stays [SMD (95% CI) 0.05 (− 0.09, 0.19); p = 0.49] were also similar between recruitment maneuver group and standard lung protective ventilation group. Risk of barotrauma was also similar.

Conclusion

Use of recruitment maneuver along with co-interventions such as PEEP titration does not provide any benefit in terms of mortality, length of ICU, and hospital stay in ARDS patients.

Percutaneous dilatational tracheostomy through paramedian technique and lateral approach in a patient with cervical esophagostomy-a case report

BACKGROUND

Percutaneous dilatational tracheostomy (PDT) is a common surgical procedure and established as first choice for securing the airway in critically ill patients needing prolonged mechanical ventilation. There are case reports of open tracheostomy through paramedian approach without complications. This case report presents a case of PDT through paramedian approach.

CASE REPORT

An 18 year old female, case of firearm injury underwent cervical esophagostomy on the left side of neck approaching midline. So we perform PDT through paramedian technique and lateral approach safely with use of real time ultrasound and fiberoptic bronchoscope.

DISCUSSION

PDT can be done through paramedian technique and lateral approach to trachea safely with help of ultrasound and fiberoptic bronchoscope in the conditions where midline approach is not feasible and unsafe.

Levosimendan does not provide mortality benefit over dobutamine in adult patients with septic shock: A meta-analysis of randomized controlled trials

OBJECTIVES

Despite of advancement in intensive care medicine, sepsis and septic shock carry a high mortality. Levosimendan, an inodilator, may be promising for septic shock patients with myocardial dysfunction; however, firm evidence is lacking. In this meta- analysis of randomized controlled trials, levosimendan has been compared with dobutamine in adult patients with sepsis and septic shock.

DESIGN

Meta-analysis of randomized controlled trial.

SETTING

Intensive-care unit.

PARTICIPANTS

Adult septic shock patients.

INTERVENTION

Adult septic shock patients received dobutamine or levosimendan.

MAIN OUTCOME MEASURE

Mortality at longest follow-up, blood lactate level, cardiac index and noradrenaline requirement.

RESULTS

Data from 7 randomized trials have been included in this meta-analysis. Levosimendan has no benefit in terms of mortality at longest follow up in comparison to dobutamine (Odds ratio 0.77, 95% CI 0.45, 132; p=0.34) and length of ICU stay (MD -4.7days, 95% CI -10.3, 0.9days, p=0.10). Patients received levosimendan had less blood lactate level (standardized mean difference -0.95; 95% CI -1.64, -0.27; p=0.006) and higher cardiac index (mean difference 0.44; 95% CI 0.17, 0.71; p=0.001). Noradrenaline requirements are similar in both the groups.

CONCLUSION

There is no evidence that levosimendan is superior to dobutamine in adult patients with sepsis and septic shock. Further large randomized trials are necessary in this area.

Enteral nutrition practices in the intensive care unit: Understanding of nursing practices and perspectives

Background:

Adequate nutritional support is important for the comprehensive management of patients in intensive care units (ICUs).

Aim:

The study was aimed to survey prevalent enteral nutrition practices in the trauma intensive care unit, nurses’ perception, and their knowledge of enteral feeding.

Study Design:

The study was conducted in the ICU of a level 1 trauma center, Jai Prakash Narayan Apex Trauma Centre, AIIMS, New Delhi, India. The study design used an audit.

Materials and Methods:

Sixty questionnaires were distributed and the results analyzed. A database was prepared and the audit was done.

Results:

Forty-two (70%) questionnaires were filled and returned. A majority (38) of staff nurses expressed awareness of nutrition guidelines. A large number (32) of staff nurses knew about nutrition protocols of the ICU. Almost all (40) opined enteral nutrition to be the preferred route of nutrition unless contraindicated. All staff nurses were of opinion that enteral nutrition is to be started at the earliest (within 24–48 h of the ICU stay). Everyone opined that the absence of bowel sounds is an absolute contraindication to initiate enteral feeding. Passage of flatus was considered mandatory before starting enteral nutrition by 86% of the respondents. Everyone knew that the method of Ryle's tube feeding in their ICU is intermittent boluses. Only 4 staff nurses were unaware of any method to confirm Ryle's tube position. The backrest elevation rate was 100%. Gastric residual volumes were always checked, but the amount of the gastric residual volume for the next feed to be withheld varied. The majority said that the unused Ryle's tube feed is to be discarded after 6 h. The most preferred (48%) method to upgrade their knowledge of enteral nutrition was from the ICU protocol manual.

Conclusion:

Information generated from this study can be helpful in identifying nutrition practices that are lacking and may be used to review and revise enteral feeding practices where necessary.
