Incidence of obesity in parturients scheduled for caesarean section, intra-operative complications, management and outcome
Abstract
Objectives: To determine the incidence of obesity in parturients scheduled for Caesarean section, identify intra-operative complications, management and outcome.
Design: A prospective observational study.
Setting: University of Benin Teaching Hospital, a university-affiliated tertiary centre.
Subjects: Parturients scheduled for Caesarean section excluding patients in American Society of Anaesthesiologists (ASA) health status 4 and 5.
Results: Three hundred patients were recruited in the study. One hundred and forty eight (49.3%) were non – obese (BMI < 30kgm2) while 152 (50.7%) were obese (BMI >30kgm –2). The incidence of obesity was extremely significant P<0.0001, t = 19.721 and 95% C.I. = 11.998 – –9.820. Twenty four percent of the obese and 6% of the non-obese parturients had intercurrent medical diseases. 40.5% of the non-obese parturients had general anaesthesia while 13.1% of the obese parturients were offered general anaesthesia. The incidence of intra-operative complications was higher in the obese group. P<0.0001; extremely significant. Odds ratio = 3.647; 95% C.I. of 2.0007 – 6.626. The most common complications were hypotension (n = 14), shivering (n = 12) and inadequate anaesthesia (n = 8).
Conclusion: There is a high incidence of obesity in parturients. This group of patients constitutes a high risk group in obstetric anaesthesia. The incidence of complications was higher in the obese than in the non-obese.
