Tracheostomy a lifesaving procedure done more frequently for critically ill patients for mechanical ventilation, bronchopulmonary toileting, reduce pulmonary effort has variable complications to itself. The common being secondary infection with bacteria and fungi, which in turn lead to granulation formation in stoma and on peristomal region. This prospective study was done with an aim to study, correlate and compare the microbial organisms grown in culture from tracheostomy tubes and peristomal granulation in ventilated and non-ventilated patient. We studied 210 patients out of them 100 patients satisfied the inclusion and exclusion criteria and they were included in this study. We found 89 patients staining positive for bacterial cultures and 8 patients staining positive for fungi and the granulation increases as the time taken for tube change is more than 1 month. So, we concluded it is ideal to change tracheostomy tube within a month duration and most common organism complicating infection in stoma as followed by coagulase negative .
气管切开术是一种为重症患者进行机械通气、支气管肺灌洗、减轻肺部负担而更频繁实施的挽救生命的手术，其本身存在多种并发症。常见的是继发细菌和真菌感染，进而导致造口处和造口周围区域形成肉芽组织。本前瞻性研究旨在研究、关联和比较气管切开管培养物中生长的微生物与通气和非通气患者造口周围肉芽组织中的微生物。我们研究了210例患者，其中100例患者符合纳入和排除标准并被纳入本研究。我们发现89例患者细菌培养呈阳性，8例患者真菌培养呈阳性，并且当气管切开管更换时间超过1个月时，肉芽组织会增加。因此，我们得出结论，在1个月内更换气管切开管是理想的，造口感染最常见的并发症微生物依次为凝固酶阴性菌。
