Extracorporeal membrane oxygenation in COVID-19- Associated acute respiratory distress syndrome - Outcome and experience in a tertiary care intensive care unit - A retrospective study.

Background: Extracorporeal membrane oxygenation (ECMO) has been used in patients with severe acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19) who fail conventional treatment. Methods: A retrospective observational study was designed in patients who underwent ECMO for severe COVID-19 ARDS in a tertiary care centre from September 2020 to July 2021. The primary outcome was to assess factors influencing clinical outcomes and survival to hospital discharge. Secondary outcomes were to assess the clinical profile and pre-ECMO features, ECMO characteristics and complications. Collected data were entered in Excel software and analysed using R software version 4.0.2 (R foundation for statistical computing, Vienna, Austria). Results: A total of 19 patients underwent ECMO. Ten patients survived and discharge. Survivors had a longer median (interquartile range [IQR]) duration (days) on ECMO, that is, 25 (7-50), compared to non-survivors, that is, 12 (1-34) (P = 0.133). We also noted that patients who survived had a longer median (IQR) duration (days) of intensive care unit (ICU) stay, that is, 41.5 (30-70), compared to non-survivors, that is, 9 (2-40) (P = 0.001). Conclusion: In our study, 52.3% of patients survived and discharge, and with ECMO outcomes for COVID-19 ARDS were at par with ECMO outcomes for non-COVID-19 ARDS despite requiring ECMO for longer duration and increased ICU length of stay.

Practice Patterns in the Diagnosis and Management of Alcohol Withdrawal Syndrome in Indian Intensive Care Units.

Alcohol use disorders (AUDs) are prevalent in intensive care units (ICUs). Alcohol abuse and/or dependence, leading to alcohol withdrawal syndrome (AWS), is as high as 10% or more. There seem to be wide variations in management strategies used to manage these patients, prompting an evaluation of the knowledge gap as well as finding the barriers. Noting lack of such literature in the Indian setting, a survey is undertaken to evaluate practice patterns surrounding the identification and management of alcohol dependence/abuse and AWS in the Indian critical care scenario. The main respondents of the survey are independent practitioners with anesthesia as their base specialty and overwhelmingly practice in multidisciplinary ICUs. They estimated AUD prevalence to be under 10%. The reason most expressed for lack of AUD documentation is fear of insurance rejection. Very few used risk assessment tool in evaluation of AUDs and AWS. Awareness of ICD 10/DSM-V components of AWS diagnosis was negligible. Chlordiazepoxide and lorazepam were used either in a fixed- or symptom-based therapy. Compared to available literature, haloperidol use is excessive, while barbiturates rarely. The wide variation is seen with the dose and frequency of thiamine in AWS without neurological complications. The impact on mortality and morbidity is poorly understood. In conclusion, the survey reported a lower prevalence compared to international literature. Insurance rejection is one of the main factors in limiting adequate history taking or documenting AUDs. Alcohol withdrawal syndrome risk assessment, monitoring, and management is variable and suboptimal. Variability in all aspects of AUDs is attributable to the knowledge gap. Further studies are needed to bridge the research gap. How to cite this article: Gopaldas JA, Padyana M, Rai PP.

Adverse Events during Intrahospital Transport of Critically Ill Patients: A Multicenter, Prospective, Observational Study (I-TOUCH Study).

Background: Critically ill patients are frequently transported to various locations within the hospital for diagnostic and therapeutic purposes, which increases the risk of adverse events (AEs). This multicenter prospective observational study was undertaken to determine the incidence of AEs related to intrahospital transport, their severity, and their effects on patient outcomes. Patients and methods: We included consecutive unstable critically ill patients requiring intrahospital transport, across 15 Indian tertiary care centers over 5 months (October 11, 2022-February 20, 2023). Apart from the demographics and severity of illness, data related to transport itself, such as indications and destination, incidence of AEs, their category and treatment required, and patient outcomes, were recorded in a standard form. Results: Eight hundred and ninety-three patients were transported on 1065 occasions out of the intensive care unit (ICU). The mean (SD) acute physiology and chronic health evaluation II score of the patients was 15.38 (±7.35). One hundred and two AEs occurred, wherein cardiovascular instability was the most common occurrence (31, 30.4%). Two patients had cardiac arrest immediately after transport. Acute physiology and chronic health evaluation II [odds ratio (OR): 1.02, 95% confidence interval (CI) - 1.00-1.05, p = 0.04], emergent transport (OR: 5.11, 95% CI - 3.32-7.88, p = 0.00), and team composition (OR: 5.34, 95% CI - 1.63-17.5, p = 0.00) during transport were found to be independent predictors of AEs. Conclusion: We found a high incidence of AEs during intrahospital transport of critically ill patients. These events were more common during emergent transports and when the patients were transported by doctors. Transport by itself was not related to ICU mortality. We feel that stabilization of the patients before transport and adherence to a standardized protocol may help in minimizing the AEs, thereby enhancing patient safety.

Clinical Profile and Outcome of Dengue Fever in Multidisciplinary Intensive Care Unit of a Tertiary Level Hospital in India.

BACKGROUND: India is one of the seven identified countries in South-East Asia region regularly reporting dengue fever (DF)/dengue hemorrhagic fever (DHF) outbreaks. Even though the dengue prodrome and evolution of illness are most often similar in many patients, progress and outcome may differ significantly depending on the severity of illness as well as treatment instituted. We studied the clinical manifestations, outcome and factors predicting mortality of serology confirmed dengue fever cases admitted in Multidisciplinary Intensive Care Unit (MICU) of a high acuity healthcare facility in India. METHODOLOGY: All patients with serology proven dengue fever admitted to MICU between 1st July 2015 and1st December 2015 were included in the study. Clinical presentation, laboratory findings, severity of illness scores and outcome were recorded. RESULTS: Majority of the patients (58.4%) belonged to 21-40 year age group. Hepatic (96.8%) followed by hematological (79.2%) involvement were the most common findings. CNS involvement observed among 27%. Survival to hospital discharge was 78.9%. Respiratory and gastrointestinal system involvement was associated with increased mortality. Acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and shock were the clinical syndromes associated with mortality. Serum lactate, aspartate transaminase (AST) and alanine transaminase (ALT) were significantly elevated among non survivors. Significant difference in sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation (APACHE) scores was also observed among survivors and non survivors. CONCLUSION: Organ system involvement and higher disease severity scores are strong predictors of mortality. High index of suspicion for atypical manifestations of dengue is warranted.

Volume Conductivity and Scatter Parameters as an Indicator of Acute Bacterial Infections by the Automated Haematology Analyser.

INTRODUCTION: Complete blood picture is the first and foremost investigation ordered for evaluation of acute infectious processes which require early and prompt intervention. With the advent of automated Coulter (®) Haematology analysers, the Volume, Conductivity & Scatter parameters of the leucocytes could be analysed for the early detection of the infections. AIM: To evaluate the clinical usefulness of Volume, Conductivity & Scatter parameters of neutrophils & monocytes in predicting the onset of acute bacterial infections. MATERIALS AND METHODS: Peripheral blood samples from 94 patients with infections (systemic infections n=36 & localised infections n=58) and 46 control subjects were studied using the Volume, Conductivity & Scatter parameters by the Coulter Haematology analyser. RESULTS: We observed a significant increase in the mean channel of neutrophil volume & mean channel of monocyte volume from patients with infections (both systemic & localised) as compared with control subjects (Mean Neutrophil Volume: 158.3 ± 13.7 vs 137.2 ± 4.3; p<0.001) & (Mean Monocyte Volume: 177.8± 16 vs 161.7 ± 6.04; p <0.001). However, there was no significant difference in the Mean Neutrophil Volume of patients with systemic infection & localised infections (160.5±17.5 vs 156.8±10.5, p>0.05). CONCLUSION: The Volume, Conductivity & Scatter parameters like Mean Neutrophil Volume & Mean Monocyte Volume are more sensitive parameters and could prove to be a quick diagnostic indicator of acute bacterial infections.

Microbiological Profile and Drug Sensitivity Pattern among Community Acquired Pneumonia Patients in Tertiary Care Centre in Mangalore, Coastal Karnataka, India.

BACKGROUND: Community Acquired Pneumonia (CAP) is the most common respiratory tract infection in day to day practice. The knowledge of organism commonly causative of CAP helps in early empirical treatment initiation. AIM: To study the microbiological profile of patients with community acquired pneumonia and to study drug sensitivity pattern. METHODS: Hospital based cross sectional study among 100 patients with CAP was conducted in a tertiary care hospital of Southern India. Sputum culture showed that out of 100 patients 39 had an identifiable etiology with 12 patients having evidence of mixed infection. RESULT: Micro-organisms isolated in sputum culture were Streptococcus pneumoniae (31%) followed by, Pseudomonas pyogens (15%), Klebsiella pneumoniae (13%). AFB smear was found to be positive in 6 patients. Organisms were found to be sensitive for piperacillin plus tazobactum (41%), aminoglycocides (amikacin-46%, gentamicin-31%), third generation cephalosporins (Cefotaxim-36%, Ceftriaxone-18%) and macrolides (Erythromicin-31%, Azithromycin-18%). Sensitivity to chloramphenicol was observed in 31% sputum culture positive patients. Ciprofloxacin sensitivity was seen among 49%. CONCLUSION: Most of the organisms were found to be sensitive to monotherapy with extended spectrum beta lactamases, third generation cephalosporins, fluroquinolones, macrolides.

Castleman's Disease with Paraneoplastic Pemphigus.

Castleman's disease is a rare autoimmune disorder with varied clinical presentations. Castleman's commonly involves mediastinum and hence it is thoracic in most of the reported cases. Paraneoplastic pemphigus (PNP) and myasthenia gravis can be associated with multicentric Castleman's disease. Its association with HIV, Kaposi sarcoma, and lymphoma is also well known. We report a rare combination of unicentric, extrathoracic Castleman's disease with PNP and myasthenia gravis.

HIV in Females: A Clinico-epidemiological Study.

BACKGROUND: Human Immunodeficiency Virusinfected women account for almost half the number of cases of HIV worldwide. Despite reduction in HIV prevalence among the population, the percentage of Indian women contracting the disease seems to have increased. The social implications are also different in females. MATERIALS AND METHODS: This prospective observational study was conducted from September 2009 to July 2011 at tertiary care hospitals attached to the Kasturba Medical College Mangalore, on a group of 200 HIV-positive patients. Patients above 18 years of age diagnosed with HIV as per National AIDS Control Organisation guidelines were included in the study. Clinical profile among women and men was compared with respect to clinical presentation, disease detection, CD4 count and response of family and society. RESULTS: Clinical presentation was similar among both men and women. Eighty-one percent men had promiscual sexual exposure, 19% of women had so. Males were identified to be HIV-positive earlier than their spouse (tested later), time lag being 27.6 weeks. After detection of positivity 77% of females felt being less cared for by the in-laws. CD4 count less than 50 was detected in more number of females as compared to men (11% females and 1% males). Death of spouse was seen more often in females (among 35% of women and 11% of men). CONCLUSION: Most of the females were likely to acquire infection from their spouse. Females tend to seek and get medical attention at the late stage of disease as compared to men. HIV in females has different social implications which includes discrimination within the family.

HIV-Tuberculosis: A Study of Chest X-Ray Patterns in Relation to CD4 Count.

BACKGROUND: Fight against human immunodeficiency virus (HIV) is incomplete without addressing problems associated with difficult diagnosis of tuberculosis in HIV-Tuberculosis coinfected patients. Chest X-ray is a primary tool to evaluate tuberculosis in HIV. AIM: To assess and compare various radiological patterns of pulmonary tuberculosis in HIV patients and compare these patterns in relation to CD4 counts. MATERIALS AND METHODS: Prospective cohort study was conducted in a tertiary hospital in South India from September 2009 to July 2011 with 200 HIV positive patients. WHO guidelines were used for diagnosis of HIV and tuberculosis. RESULTS: 27% of the patients had sputum positive pulmonary tuberculosis, with higher incidence (33%) among CD4 less than 200 as compared to CD4 more than 200 (14%). Infiltration (39%) followed by consolidation (30%), cavity (11%), and lymphadenopathy (9%) seen with CD4 less than 200. Infiltration (37.5%) followed by cavity (25%) and miliary (25%) with CD4 above 200. Bilateral (68.5%) and mid and lower zones or all zone involvement more commonly seen. CONCLUSION: In patients with CD4 lower than 200 noncavitory infiltration and consolidation predominated. Involvement of lungs was atypical; diffuse or mid and lower zone involvement than classical upper lobe involvement. A high index of suspicion is necessary for the accurate and timely diagnosis of tuberculosis in HIV positive patients.
