What is the incidence and what are the contributing factors for early post-operative hypoxemia among patients undergoing surgery under anesthesia?
Early post-operative hypoxemia is common (26.7%) among surgical patients, highlighting the need for supplemental oxygen in high-risk patients, including those with heart disease or prolonged surgeries.
ABSTRACT Background: Hypoxemia is defined as low level of oxygen in the blood. The early postoperative period is a critical time for developing hypoxemia. It is well known that the physiological response of the patient is not reversed immediately after anesthesia and surgery. Supplemental oxygen should be considered in patients who had operation under anesthesia at the potential time of post-operative period. Objective: The objective of this study was to determine the incidence of early post-operative hypoxemia and its contributing factors among operated patients under anesthesia during transportation to recovery rooms and at recovery rooms. Methods: A prospective observational study design was conducted to determine the incidence of early post-operative hypoxemia and to identify the contributing factors among operated patients who had undergone with anesthesia from March 1 to April 10, 2018. Data were checked on daily basis. Data were entered to Epi Info and analyzed by statistical package for social sciences (SPSS) version 20 software. Descriptive statistics were used to summarize patient's sociodemographic data. Bivariate and multivariate binary logistic regressions were conducted to see the existence of the association between dependent and independent variables. Results: 424 operated patients were included. The overall incidence of early post-operative hypoxemia among the study subjects (424) was 113 (26.7%). The risk factors of early post-operative hypoxemia were preoperative oxygen saturation 120 min, muscular strength score 0 and hepato-biliary-pancreas surgeries. Therefore, oxygen administration should be commenced to all risky patients for hypoxemia during early post-operative period. Highlights:
Melesse et al. (Wed,) conducted a observational in Post-operative hypoxemia (n=424). Surgery under anesthesia was evaluated on Incidence of early post-operative hypoxemia. Patients undergoing surgery under anesthesia experienced a 26.7% incidence of early post-operative hypoxemia, with risk factors including preoperative O2 saturation <95% and general anesthesia.
