ISCCM Position Statement: Management of Severe Dengue in Intensive Care Unit.

Dengue is one of the commonest causes of undifferentiated acute febrile illness in India as well as South East Asia. Nearly two-fifths of the world population is at risk of infection, and nearly 96 million infections reported worldwide, it is a major cause of concern across the globe. The ISCCM leadership felt that there have been no new directives/guidelines except the MOH guidelines for the management of dengue fever since 2014. Under the auspices of the Indian Society of Critical Care Medicine (ISCCM), an expert group of 14 intensivists from across the country, was formed. The task force members formulated questions that needed to be answered. These questions were validated by the members of ISCCM attending research conclave 2023. All the members systematically searched PubMed, MEDLINE, and Science Direct for original articles on different aspects of dengue management between January 1, 2000, and July 1, 2023. From the collected articles, duplicates were removed. Based on the evidence collected, the expert group members prepared statements/answers to the questions. Since most of the evidence is of moderate to low quality, a consensus was generated amongst the members of the task force. Each statement was agreed upon by 70% of the task force. The statements presented in the article are consensus statements as answers to queries raised. How to cite this article: Bhalla A, Singh H, Suri V, Yaddanapudi L, Poddar B, Ghawat R, et al.

Delayed Transfer of Critically Ill Patients from Emergency Department to Intensive Care Unit.

Background and aim: Delay in the transfer of critically ill patients from the emergency department (ED) to intensive care units (ICUs) may worsen clinical outcomes. This prospective, observational study was done to find the incidence of delayed transfer. Materials and methods: After approval from the institute ethics committee and written informed consent, all patients admitted to ICU from ED over 6 months were divided into groups I and II as patients getting transferred to ICU within 30 minutes of the decision or not, respectively. The factors affecting the immediate transfer and clinical outcome of all patients were noted. Monthly feedback was given to the ED team. Results: Out of 52 ICU admissions from ED, 35 (67.3%) patients were not transferred within 30 minutes, and the most frequent factor preventing immediate transfer was ED-related (54%). A statistically significant difference was found in acute physiology and chronic health evaluation (APACHE II) score, clinical deterioration during transfer, longer duration of mechanical ventilation and length of stay, and higher mortality with patients transferred immediately to ICU. A reduction of 42.6% was noted in transfer time from the first month to the last month of study. Conclusion: The incidence of delayed transfer of patients from ED to ICU was 67.3% with ED-related factors being the most frequent cause of delay (54.2%).

Comparison of Commercially Available Balanced Salt Solution and Ringer's Lactate on Extent of Correction of Metabolic Acidosis in Critically Ill Patients.

INTRODUCTION: Appropriate early fluid resuscitation is ubiquitous for critically ill patients with metabolic acidosis. Owing to harmful effects of normal saline, commercially prepared balanced salt solutions are being used. However, there is no study comparing use of Ringer's lactate (RL) and commercially available balanced salt solutions in critically ill patients. MATERIALS AND METHODS: A randomized controlled trial was conducted during July 2016 to December 2017. Fifty adult patients admitted to intensive care unit with metabolic acidosis were randomized into group RL or group acetate solution (AC). Respective trial fluid was administered at 20 mL/kg/hour for first hour and 10 mL/kg/hour for second hour. Arterial blood gas analysis samples were taken 15 minutes apart. The fluid resuscitation was continued till pH got corrected to 7.3 or 2 hours, whichever was earlier. The primary aim was to compare time to correct metabolic acidosis in both the groups. The secondary outcomes were the extent of correction of metabolic acidosis, total volume of fluid used, and total cost per patient. RESULTS: Demographic parameters, APACHE II score, and baseline investigations were comparable. The metabolic acidosis got corrected in 12 patients in group AC and 10 patients in group RL (p value = 0.66). The mean time for correction of metabolic acidosis was 57 ± 3.85 minutes in group RL and 56.25 ± 4.22 minutes in group AC (p value =0.95). The extent of correction of metabolic acidosis and total volume of fluid used was also comparable (p value = 0.05). However, the cost of fluid used was significantly higher in group AC (p value < 0.01). CONCLUSION: During administration of balanced salt solutions, RL or AC, in critically ill patients with metabolic acidosis, AC did not confer any advantage in time to or extent of correction of metabolic acidosis. CLINICAL SIGNIFICANCE: There is no difference in acid-base status with use of different types of balanced salt solutions for resuscitation in critically ill patients.

Derivation and validation of a formula for paediatric tracheal tube size using bootstrap resampling procedure.

BACKGROUND AND AIMS: The accuracy of age-, length- and weight-based formulae to predict optimal size of uncuffed tracheal tubes (TTs) in children varies widely. We determined the accuracy of age, length and weight in predicting the size of TT in Indian children, and derived and validated a formula using the best predictor. METHODS: In the derivation phase, 100 children aged 1-8 years undergoing general anaesthesia and tracheal intubation with an uncuffed tube were prospectively studied. The correct size of the TT used was confirmed using the leak test. A bootstrap resampling procedure was used to estimate the accuracy of the predictors (age, weight, or length alone; length and age; length and weight; and length, weight and age). The best predictor was used to derive a formula (Paediatric Tube Size Predictor, PTSP) to calculate the size of TT. The accuracy of PTSP was tested in 150 children of the same age group in the validation phase. RESULTS: Length (L (in meters), R 2 = 0.61) was the best single predictor of the size of TT and was used to derive the PTSP as internal diameter = 3L + 2.5. In the validation phase, the PTSP predicted the size of TT correctly in 75% of children. Re-intubation was associated with a higher incidence of respiratory morbidity than one-time tracheal intubation. CONCLUSION: Length of the child predicts the size of an uncuffed TT better than age and weight. The PTSP formula based on length correctly predicts the size of uncuffed TT in 75% of children.

Effect of Intensive Education and Training of Nurses on Ventilator-associated Pneumonia and Central Line-associated Bloodstream Infection Incidence in Intensive Care Unit at a Tertiary Care Center in North India.

OBJECTIVE: The aim was to analyze the impact of education and training of nurses on the incidence of ventilator-associated pneumonia (VAP) and central line-associated bloodstream infection (CLABSI). PATIENTS AND METHODS: A prospective observational study at a tertiary care hospital included adult patients with Intensive Care Unit stay >48 h. The study was done in three phases: in Phase 1, baseline VAP and CLABSI incidence was calculated; in Phase 2, education and training of nurses; and in Phase 3, data were recollected for the incidence of VAP and CLABSI. RESULTS: The baseline incidence of VAP in Phase 1 was 28.86/1000 ventilator days and that of CLABSI was 7.89/1000 central-line days. In Phase 3, the incidence of VAP increased to 35.06 and that of CLABSI decreased significantly, 1.73. CONCLUSION: Intensive education and training sessions with feedback from nurses over a period of 6 months led to significant reduction in the incidence of CLABSI; however, the incidence of VAP increased.

Intensive care unit-acquired infections in a tertiary care hospital: An epidemiologic survey and influence on patient outcomes.

BACKGROUND AND OBJECTIVE: Nosocomial infections are common in intensive care units (ICUs), but the pattern of infections and the distribution of microorganisms vary. We studied the ICU-acquired infections and their effect on patient outcomes in our ICU. METHODS: Patients admitted to our ICU for >48 hours were studied prospectively over a year. Infections were diagnosed based on Centers for Disease Control and Prevention guidelines. Antibiotics were administered based on culture and sensitivity. Univariate and multivariate logistic regressions were carried out to determine the factors associated with infection. RESULTS: One hundred ninety-eight patients were studied. The crude infection rate was 50% with ventilator-associated pneumonia (40%) and bloodstream infection (21%) being the most common. Acinetobacter calcoaceticus-baumannii complex, Pseudomonas aeruginosa, and Klebsiella pneumoniae were the most common microorganisms. More than 90% of patients received antibiotics, the most common being ß lactam-ß lactamase inhibitors, aminoglycosides, fluoroquinolones, and carbapenems. Thirty-five percent of staphylococci were methicillin-resistant, 50% of Enterococcus strains were vancomycin-resistant, and 68% of Acinetobacter calcoaceticus-baumannii complex, 47% of Pseudomonas strains, and 35% of Klebsiella strains were multidrug-resistant. A longer duration of ventilation was associated with infection. The overall ICU mortality rate was 24% and was similar in patients with or without infection. CONCLUSIONS: The incidence of infection and the multidrug resistance in the ICU was high. Infection was associated with duration of ventilation but not mortality.
