Abstract:Objective To observe the efficacy of ultrasound-guided subcostal transversus abdominis plane block on postoperative analgesia for patients undergoing caesarean section. Methods Fifty ASAΙto Ⅱ pregnant women undergoing caesarean section by subarachnoid anesthesia were randomized into 2 groups(N=25 each):Group T and Group S. Patients in Group T were received subcostal transversus abdominis plane block (TPAB)guided by ultrasound with 0.375% Ropivacaine 15ml each side after operation.Patients in Group S were received physiological saline. All patients received patient controlled intravenous analgesia(PCIA) after operation. 6 hours, 12 hours,24 hours and 48 hours after the operation, visual analog pain (VAS) grade, analgesic pump delivery dosage and out-of-bed activity time were compared between the two groups. 6 hours and 12 hours after the operation, the VAS grade in the Group T was obviously lower than that in the Group S(P<0.05), while 24 hours and 48 hours after the operation,there was no obvious difference (P>0.05). The dosage of patient-controlled analgesia and out-of-bed activity time in the Group S were much more than those in the Group T(P<0.05). In Group T, there was no difference of postoperative VAS grade and PCA dosage between transverse incision and vertical incision (P>0.05). Adverse reactions caused by TAP puncture were not found.
