Early Postoperative Cognitive Dysfunction in Women Undergoing Elective and Emergent Caesarian Section under General Anaesthesia: A Comparative Study

Abstract

Background: Postoperative cognitive dysfunction (POCD) following cesarean section (CS) is a growing and underestimated problem with unknown mechanisms. Studies suggest that general anesthesia (GA) plays a role in the development of early POCD. Objectives: This study aimed to assess the incidence of early POCD after elective and emergent CS under GA. Methods: We assessed the difference between the elective and emergent groups regarding the mini-mental state examination (MMSE), hemodynamic effects such as mean blood pressure (MBP), and heart rate (HR). Paired t-test was applied for intragroup comparison, and Student’s t-test (or Mann–Whitney U test, as appropriate) for intergroup comparison. Results: MMSE one hour after the operation was significantly lower than preoperative MMSE in the emergent group, and the MMSE tended to return to normal values faster in the elective than in the emergent group. Moreover, we found a significantly lower MBP and higher HR (at 15, 30, and 45 minutes) in both groups compared to preoperative values. Regarding intergroup comparison, MBP (at 30 minutes) significantly decreased in the elective group compared to the emergent group. Conclusions: There was a significantly lower POCD, especially at the first hour postoperatively, in the elective CS than in the emergent CS. Elective CS might have a positive effect on the women’s health as a mode of delivery.
