Abstract:
Objective To investigate the effect of ultrasound-guided transversus abdominis plane (TAP)block on the efficacy of postoperative analgesia in parturients undergoing selective cesar-ean delivery.Methods Eighty ASA Ⅰ or Ⅱ parturients recruited for selective cesarean delivery under combined spinal-epidural anesthesia were randomly divided into two groups(n =40 each):TAP group (group T)and control group(group C).After cesarean delivery,bilateral of ultrasound-guided TAP block were performed,20 ml of 0.5% ropivacaine was injected in each side in group T,while TAP was not done in group C.Both groups received patient-controlled intravenous analgesia (PCIA)after cesarean delivery.The resting and exercise visual analogue scale (VAS)scores,Ramsay sedation score and the Bruggrmann comfort scale(BCS)score were evaluated at 2,4,6,8 and 24 h after operation. The consumption of sufentanil within 24 h after operation,the number of successfully delivered doses (D1 )and the number of attempts (D2 )within 24 hr after operation were recorded.D1/D2 was calculated.The parturients satisfaction and the adverse reactions were also recorded.Each parturient was assessed postoperatively by a blinded investigator.Results The consumption of sufentanil within 24 hr after operation,the resting and exercise VAS scores at 2,4,6 hr after surgery were significant-ly lower,while the BCS score,the value of Dl/D2 and the degree of satisfaction were higher in group T than those in group C (P <0.05).There were no adverse reactions in both groups.Conclusion Ultra-sound-guided TAP block reduces the postoperative sufentanil consumption,enhances the efficacy of post-cesarean analgesia of the parturients.Comfort and satisfaction are achieved in the parturients of the group T.
