Abstract

OBJECTIVE: We aimed to compare the effect of general and spinal anesthesia on maternal blood loss in elective cesarean section (CS).

MATERIAL AND METHODS: This was a prospective randomized study and included 418 healthy pregnant women with a term uncomplicated singleton pregnancy between 37 and 41 weeks of gestation. The study participants were randomly divided into two groups: the general anesthesia group and spinal anesthesia group. CSs were all performed using the same surgical technique, and within the groups, the same anesthetic procedures were used (either general or spinal). The primary outcome for this study was operative blood loss. Hemoglobin and hematocrit concentrations were compared between the two groups.

RESULTS: The preoperative hemoglobin and hematocrit levels were similar in the both groups (p=0.08 and p=0.239, respectively). Significantly lower operative blood loss was achieved using spinal anesthesia versus general anesthesia during elective CS. The differences between preoperative and postoperative blood values for both the study groups were statistically significant (p<0.001).

CONCLUSION: This study demonstrates that spinal anesthesia is associated with a lower risk of operative blood loss than general anesthesia in low risk patients undergoing elective CS.
