Abstract
Introduction: Hypoxemia is defined as a low amount of oxygen in our blood. Early
postoperative hypoxemia leads to cellular ischemia which may delay recovery and complications
are associated with significant cost and mortality implications for patients.
Objectives: The objectives of the study was to determine the magnitude and associated factors
of hypoxemia in pediatric patients aged 1-14 years who undergone surgery under general
anesthesia in Tikur Anbessa specialized hospital from October 26, 2019 to February 26, 2020
G.C.
Method: Institutional based cross sectional study was conducted at Tikur Anbessa specialized
Hospital, Addis Ababa, Ethiopia data was collected from October 26/2019 to February 26, 2020
using a pre-tested questionnaire starting from preoperative period to postoperative period in
PACU. After sample size was calculated and systematic random sampling technique applied, 229
patients included in the study. The data was entered to Epi Info version 7.2.1 and analyzed by
SPSS version 22 software performing descriptive statistics, bivariate and multivariate logistic
regression.
Result: The incidence of early postoperative hypoxemia is found to be 44.5%. Muscle relaxant
use has a 3.13 times [AOR=3.13; 95% CI: (1.13-8.64)] and not using premedication has 10 times
[AOR=10.93; 95% CI: (4.74-25.21) more risk for developing early post-operative hypoxemia.
Duration of surgery greater than an hour has 4.6 times [AOR=4.68; 95 % CI: (2.01-10.89)] and
duration of anesthesia greater than an hour has 11 times [AOR=11.29; 95% CI: (3.96-32.19)]
risk for early post-operative hypoxemia.
Conclusion and recommendation: The magnitude of early postoperative hypoxemia is high.
Some of the identified factors were muscle relaxant use, duration of surgery and anesthesia
greater than an hour therefore it’s important to give attention for patients undergoing long
surgical procedures and for patients who took muscle relaxants.
