IMPACT OF OBESITY ON FUNCTIONAL AND TOMOGRAPHIC RESPIRATORY SEQUELAE OF PATIENTS HOSPITALIZED FOR COVID-19

Abstract

Background: The Montgomery-type prosthesis, or Montgomery T-tube (MTG), is a device used for the treatment of various tracheal pathologies, such as stenosis and granulomas, as well as for postoperative management following tracheal surgery. Despite its widespread use, there is limited national evidence regarding its complications in respiratory rehabilitation settings. The objective of this study was to describe the complications associated with the use of MTG
in a Mechanical Ventilation Weaning and Rehabilitation Center (MVWRC), as well as the reasons for its placement,
postoperative medical indications, discharge status, and survival.

Materials and methods: An observational, cross-sectional, and retrospective study was conducted, including patients
aged ≥18 years admitted to the MVWRC from 2015 to 2023 who received or were indicated for MTG prosthesis
placement during hospitalization. We analyzed clinical and demographic variables, postoperative indications, associ
ated complications, duration of use, and patient discharge destinations.

Results: Fifteen patients were included, with a mean age of 53 years. The most frequent indication for placement
was tracheal stenosis (53.3%). 93.3% of patients experienced at least one complication, mainly increased secretions and the need for aspiration. One third of the patients required emergency removal of the MTG. The median duration of use was 104.5 days, and survival at discharge was 80%.

Conclusion: Most patients with a MTG experienced complications during hospitalization, with emergency removal being the most frequent intervention. Standardization of postoperative care protocols could reduce complications and optimize clinical outcomes
