GASTROINTESTINAL BLEEDING;

Abstract

Background: Gastrointestinal bleeding (GIB) among patients with critical illness is one of the leading sources of mortality and morbidity. The prevalence of GIB differs from 15-50 percent during first 24 hours stay in intensive care unit. Mechanical ventilation is a most leading risk factor of GIB among patients admitted in ICU (intensive care unit). Objectives: The objective of the study is to know the prevalence and risk factors associated with gastrointestinal bleeding among mechanically ventilated patients. Study Deign: Retrospectively study. Setting: Ch Rehmat Ali Memorial Trust Hospital, Lahore. Period: 1st October 2017 to 31st March 2018. Materials and Method: A group of 120 patients in intensive care unit who received mechanical ventilation for a period of 48 hours or above were included. Results: Among 56 patients with gastrointestinal bleeding, mean age was 49.2±12.1, mean length of ICU stay was 29.2±16.6 and mean duration of ventilation was 30.2±20.5. Among 64 patients with no gastrointestinal bleeding, mean age was 51.9±15.0, mean length of ICU stay was 12.7±6.8 and mean duration of ventilation was 13.5±7.9. There were 12 (21.1%) mortalities among patients with gastrointestinal bleeding and 10 (15.6%) mortalities among patients with no gastrointestinal bleeding. Conclusion: Study concluded that length of ICU stay, duration of ventilation, renal failure, liver failure and mortalities were more among patients with gastrointestinal bleeding.
