Abstract

Tracheostomy is a surgical procedure in an emergency setting to relieve the upper airway obstruction by creating an opening in the anterior part of trachea. It can also be done electively to wean off from a ventilator, during an elective surgery and clearance of pulmonary secretions. This study was a retrospective analysis of microbiological profile, antibiotic sensitivity & resistance pattern in patients with a tracheostomized wound. A retrospective review of the microbiological profiles of all adult patients who underwent a tracheostomy was conducted between May 2022 and May 2023 at our hospital. Based on the tracheostomy indications, patients were allocated under obstructed and non-obstructed group. Any patient with at least one positive sample was followed up quarterly for a year. The first culture result obtained was recorded at least one month following the last antibiotic dose in each quarter. Out of the 65 tracheal aspirate results obtained from 58 patients (mean age, 57.5 ± 16.48 years), the most common procedure and indications were surgical tracheostomy (72.4%) and non-obstructed causes (74.1%), respectively. Moreover, 47.7% of the culture results indicated , which showed significantly different proportions across the quarters ( = 0.006). Among obstructed patients, was the most common (35%), followed by methicillin-resistant (MRSA; 23.5%). The colonization was predominantly by gram negative bacteria Acinetobacter species, & and fungal species like followed by and non-Albicans candida.
