Effect Of Postoperative Analgesia Of Ultrasound-guided Transversus Abdominis Plane Block In Hemicolectomy Patients

ObjectiveTo investigate the effect of postoperative analgesia of ultrasound-guided transversus abdominis plane block in hemicolectomy patients.MethodsFourty (40) hemicolectomy patients randomly divided into two even groups. After anesthesia induction and intubation, patients recieved ultrasound-guided bilateral transversus abdominis plane block with0.25%ropivacaine60ml (group A) or saline (group B). Post-operative patient-controlled intravenous analgesia with sufentanil was provided to all patients.ResultsCompared with group B, group A had less BP, HR changes at skin incision and needed less intraoperative sufentanil(0.25+/-0.16μg/kg vs0.35+/-0.21μg/kg)(P<0.05) to maintain anesthesia. Group A had lower VAS than group B at1,4,8,12,24h after surgery (P<0.05), less PCA demand (2.9+/-1.6vs9.1+/-1.8)(P<0.05) and less PCA sufentanil consumption (69.1+/-5.8μg vs92.6+/-6.9μg)(P<0.05), thus less post-operative nausea or vomiting and higher satisfaction (P<0.05). No complications associated to transversus abdominis plane block were found.ConclusionUltrasound-guided transversus abdominis plane block provided safe and effective post-operative analgesia for hemicolectomy patients.
