title: [Effects of postoperative analgesia of ultrasound-guided transversus abdominis plane block in hemicolectomy patients].
abstract: OBJECTIVE
  To investigate the effect of postoperative analgesia of ultrasound-guided transversus abdominis plane block in hemicolectomy patients.
  
  
  METHODS
  After obtaining approval from the Hospital Ethics Committee and informed written consent from all patients, fourty hemicolectomy patients were randomly divided into two even groups. After anesthesia induction and intubation, patients received ultrasound-guided bilateral transversus abdominis plane block with 0.25% ropivacaine 60 ml (group A) or saline (group B). Post-operative patient-controlled intravenous analgesia with sufentanil was provided to all patients.
  
  
  RESULTS
  Compared with group B, group A had less BP, HR changes at skin incision and needed less intraoperative sufentanil ((0.25 ± 0.16)µg/kg vs (0.35 ± 0.21)µg/kg) (P < 0.05) to maintain anesthesia. Group A had lower VAS than group B at 1, 4, 8, 12, 24 h after surgery (P < 0.05), less PCA demand (2.9 ± 1.6 vs 9.1 ± 1.8) (P < 0.05) and less PCA sufentanil consumption((69.1 ± 5.8)µg vs (92.6 ± 6.9)µg) (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.
  
  
  CONCLUSIONS
  Ultrasound-guided transversus abdominis plane block provided safe and effective post-operative analgesia for hemicolectomy patients.
