Abstract:
Objective:To evaluate the correlation of preoperative pain threshold and pain tolerance threshold with postoperative sufentanil consumptions in puerperae who underwent cesarean section .Methods :A total of 50 puerperae ,aged 20‐35 years , with height 155‐180 cm ,who were classified as Ⅰ ~ Ⅱ with American Society of Anesthesiologists(ASA)criteria and scheduled for cesarean section with combined spinal and epidural anesthesia (CSEA) ,were chosen .The pain threshold and pain tolerance threshold were measured with electric stimulator before CSEA .The patient controlled intravenous analgesia(PCIA) with sufen‐tanil was used for postoperative analgesia .The PCIA pump was set up with background infusion at a rate of 0 .015μg/(kg · h) and single bolus dose of 0 .023 μg/kg with 8 min lockout interval .Visual analogue score(VAS) ,as well as consumptions of sufentanil ,was recorded at 4 ,8 ,24 h after operation .Linear correlation analysis was conducted on the preoperative pain thresh‐old and pain tolerance threshold with the total sufentanil consumptions during the 24 h after operation and the VAS at the 24 h after operation .Results :The preoperative pain threshold and pain tolerance threshold measured by electric stimulation were not correlated with the VAS at the 24 h after operation and the sufentanyl consumption during the 24 h after operation(P>0 .05) . Conclusions :The preoperative pain tolerance threshold and pain threshold measured by electric stimulation cannot predict the consumptions of sufentanyl after cesarean section .
