Background:
Metabolic syndrome (MS) is a constellation of factors associated with increased
risk of developing cardiovascular diseases and Diabetes Mellitus. Despite of the
many studies related to MS, little is known about its impact on scenarios such
as surgical anesthesia. Objective: To examine the correlation between
demographic and metabolic variables with the occurrence of perioperative
complications in patients with MS undergoing scheduled surgeries using a spinal
anesthesia technique in the surgery department at the University Clinic San
Juan de Dios in Cartagena de Indias, Colombia. Methods: Observational,
analytical, cross-sectional, single-center study of 150 subjects with MS and
150 control subjects. Perioperative complications, socio-demographic,
hemodynamic and respiratory variables were registered. Groups were compared
using t test, Fisher’s exact test or Chi-square, as appropriate. We applied a
logistic multiple regression model, adjusted by backward stepwise at 0.25 and
forward at 0.05, to find possible incompatible associations. p value < 0.05
was considered significant. Results: There were significant differences between
groups in age, American Society of Anesthesiologists physical status
classification, frequency of diseases associated to MS and perioperative
complications. There were no cases of mortality among patients. There was
statistically significant difference between the two groups for intraoperative
hypotension and hypertension with p values of <0.0001 and 0.034. Among
postoperative complications there was statistically significant difference in
pain (13.3% vs 5.3% in patients without MS) and nausea and/or postoperative
vomiting (8% vs 2% in patients without MS) with a p value of 0.027 and 0.015
(by Fisher) respectively. Conclusions: Metabolic abnormalities in MS are a risk
factor for developing complications in the perioperative period of patients
scheduled for surgeries using the
subarachnoid anesthesia technique. Accordingly, it is appropriate to implement health intervention strategies by the surgical team, aiming at their prevention
and management.
