The Use of Preoperative Salivary Amylase to Predict Postoperative Pain after Cesarean Section
Abstract Number: T-14
Abstract Type: Original Research
Our objective was to determine whether salivary amylase predicts pre and postoperative pain in patients undergoing cesarean section.
Methods: Eighty-six healthy women undergoing cesarean section under spinal anesthesia were included. Preoperatively, women were asked to fill out the State-Trait Anxiety Inventory score and to rank their anxiety score on a Verbal Analog Score (VAS anxiety). Salivary amylase was measured using the Cocorometer portable salivary amylase machine. On postoperative day 1, VAS anxiety score, pain according Verbal Analog Score (0-100), and salivary amylase were measured. Patients’ pain was reassessed according to VAS pain on postoperative days 1-4 .
Women with high postoperative pain on POD1 (VAS>50) had higher preoperative salivary amylase levels(KU/L) (49.1 ± 37.5 vs. 32.8 ± 21.2, p=0.02), higher preoperative trait anxiety inventory score levels (35.4±8.0 vs. 31.7 ± 7.3, p=0.03), and higher VAS postoperative anxiety ( 4.0± 1.4 vs. 2.2±1.4, p<0.001) when compared with women with low/moderate postoperative pain (VAS <50).
Preoperative salivary amylase may predict postoperative pain in patients undergoing cesarean section.
