ANTIMICROBIAL SUSCEPTIBILITY PATTERNS OF OF TRACHEAL TUBE ISOLATES FROM PATIENTS OF VENTILATOR ASSOCIATED PNEUMONIA (VAP) ADMITTED TO THE ICU OF A TERTIARY CARE HOSPITAL IN RAWALPINDI PAKISTAN

Abstract

AbstractThe respiratory system is a complex interconnected functionality which consists of a series of branching tubules and the lungs containing many alveoli. The alveoli are highly vascularized to provide a large surface area for gaseous exchange. The investigation was conducted in the Fauji Foundation Hospital’s Department of Microbiology from November 2019 to June 2022.. The various bacterial strains that were recovered from a total of 802 mechanically intubated individuals make up the data presented in this study.Acinetobacterspp 270 (34%),Pseudomonsspp 165(21%), andKlebsiellaspp 95 (12%) were the most frequently isolated bacteria. Main Gram-positive organisms isolated includedMethicillin-Resistant Staphylococcus aureus66 (8%), Enterococcus 48 (6%).MRSAwas 100% sensitive to Vancomycin, but only 97% sensitive to the Linezolid. TheAcinetobacterspp found in the tracheal tubes was reported to be 77% sensitive to Polymyxin B.
