ABSTRACT
Aims: Acute Respiratory Distress Syndrome (ARDS) is a known complication of acute febrile illness (AFI). The in-hospital mortality rate of ARDS is between 35-44%. Our study aimed to identify the different parameters that could be used to detect patients at higher risk of poor outcome in AFI complicated by ARDS. Methods: 130 patients with AFI complicated by ARDS as per Berlin definition, admitted at the Medical Intensive Care Unit of Seth GS Medical College & KEM Hospital Mumbai, were studied over a period of 18 months. Investigations done during the course of MICU stay were noted. From the reports, SOFA score, delta SOFA score, Lung Injury Score (LIS), Disseminated Intravascular Coagulation (DIC) score (by ISTH scoring system) were also calculated. Main outcome was recorded as transfer out from the MICU or death. Results: Etiology of the 130 patients of AFI with ARDS was as follows-dengue 32 patients (24.6%), H1N1 -31(23.8%), undifferentiated fever -30 (23.1%), leptospirosis-22 (16.9%), malaria-15 (11.5%). Our study had a mortality rate of 25.4 %( n=33). 40.8% of the study population required invasive ventilation at admission. SOFA score at admission and 48 hours, delta SOFA score, PaO2/ FiO2 ratio at admission and 48 hours, Blood Urea Nitrogen (BUN), creatinine, bicarbonate and albumin were the significant predictors of overall outcome. Hemoglobin, platelets and leukocyte counts, pH, pO 2 , pCO 2 at admission and 48 hours, Lung Injury Score (LIS) and DIC score were not significant predictors of outcome. Conclusion: SOFA score at admission and 48 hours, delta SOFA score and PaO 2 / FiO 2 ratio were significant predictors of outcome in patients of acute febrile illness with ARDS. LIS and DIC score were not significant predictors of outcome.
ABSTRACT
Background: The objective of the study was to find out different types of biological samples from admitted patients tested for culture and sensitivity (C&S), prevalence of different types of organisms isolated from those samples, and to analyze the resistance pattern of those isolated organisms against commonly used or tested anti-microbial agents (AMAs).Methods: Following institutional ethics committee approval and written informed consent, adult patients of both genders, receiving AMAs were enrolled from June 2014 to July 2015 and followed up daily till they were in medical intensive care unit (MICU). Demographic data, diagnosis, culture-sensitivity (antibiogram) and other investigation reports and treatment details were recorded. Descriptive statistical analysis of collected data was done.Results: Of the 514 samples (from 600 patients enrolled) sent for C&S testing, 143 were reported as sterile while from the rest 371 samples, 504 organisms were isolated; commonly isolated organisms were Pseudomonas aeruginosa (30%), Acinetobacter baumannii (23%), Klebsiella pneumoniae (16%), Providencia sp. (7.1%), Escherichia coli (5.7%), and Enterobacter sp. (4.2%). Samples were sent in 63% of enrolled patients, the commonest being broncho-alveolar lavage (48% of total). Microbial resistance was high for cephalosporins (ceftriaxone, cefepime, ceftazidime), carbapenems (meropenem, imipenem), penicillins (piperacillin), quinolones (ciprofloxacin, levofloxacin), aminoglycosides (gentamicin, netilmicin, amikacin) and cotrimoxazole. Most organisms were sensitive to colistin (100%), polymyxin B (92%) and tigecycline (69%).Conclusions: The information regarding commonly isolated organisms and their resistant pattern would aid in rational selection of AMAs and thus the present study is useful to clinicians managing MICU and the hospital infection committee to plan future policies regarding AMA use in MICU.
