Abstract:Objective To evaluate the efficacy of three different analgesic methods when used for postoperative analgesia in patients undergoing cesarean section. Methods A total of 90 parturients scheduled for elective cesarean section in Zhongnan Hospital of Wuhan University, from March to December 2017 were selected as research subjects. All parturients underwent cesarean delivery under combined spinal and epidural anesthesia. They were divided into patient-controlled epidural analgesia group (PCEA group), patient-controlled intravenous analgesia group (PCIA group) and continuous transversus abdominis plane block group (CTAP group) according to the random number table method, with 30 cases in each group. In PCEA group, the patients received PCEA with 0.375% Ropivacaine 2 mL after surgery, and the PCEA pump was set up to deliver a 2 mL bolus dose, a 15 min lockout interval and background infusion at a rate of 2 mL/h. In PCIA group, the patients received PCIA with Sufentanil 1 μg/mL + Tropisetron 50 μg/mL mixture 2 mL after surgery, and the PCIA pump was set up to deliver a 2 mL bolus dose, a 15 min lockout interval and background infusion at a rate of 2 mL/h. In CTAP group, bilateral TAP block was performed with 0.375% Ropivacaine 20 mL under ultrasound guidance and 0.375% Ropivacaine 6-8 mL/h was infused into bilateral TAPs by pump after surgery, the pump was set up to deliver a 6-8 mL bolus dose, a 60 min lockout interval. Analgesia lasted until 72 h after operation in all groups. When resting visual analog scale (VAS) scores≥4, Tramadol 100 mg was injected intravenously as rescue analgesia. The resting and moving VAS and Bruggrmann comfort scale (BCS) scores were recorded at immediately after the end of operation and at 2, 6, 12, 24, 36, 48, 72 hours after operation, the rate of rescue analgesia, dosage of Tramadol, the recovery time of postoperative intestinal function and lower limb motor function, and the incidence of adverse reactions were also recorded within 72 h after operation. Results Compared with PCIA group, the resting and moving VAS scores were lower and the BCS scores were higher at 6, 12, 24, 36, 48 hours after operation in PCEA group and CTAP group, the differences were statistically significant (P < 0.05), and the rate of rescue analgesia, dosage of Tramadol, recovery time of postoperative intestinal function and the incidence of adverse reactions were lower in PCEA group and CTAP group, the differences were statistically significant (P < 0.05). There were no significant differences in moving VAS scores, BCS scores, rate of rescue analgesia, dosage of Tramadol, recovery time of postoperative intestinal function and the incidence of adverse reactions between the PCEA group and the CTAP group (P > 0.05), but the recovery time of lower limb motor function in CTAP group was less than that in PCEA group (P < 0.05). Conclusion Compared with PCIA and PCEA, CTAP can provide a better obstetric analgesia and less incidence of adverse reactions when used for the patients undergoing cesarean section, and the complication of CTAP is least.
