简要总结
Can perioperative administration of intra-peritoneal local anaesthetics further reduce postoperative pain, inflammation and outcome in patients undergoing major abdominal surgery (cytoreductive surgery) and managed with thoracic epidural analgesia? - Multicenter study.
详细描述
The aim of this study is to measure the efficacy of local anesthetics (LA) administered into the intra-peritoneal cavity compared to placebo. Our hypothesis is that the injection of local LAs intra-peritoneally would reduce post-operative pain and the inflammatory process caused by the massive release of cytokines during extensive cytoreductive surgery. The study is a controlled, parallel group, double blind, prospective, randomized and performed at Sahlgrenska University Hospital in Goteborg, Sweden . Twenty mL of ropivacaine or saline would be injected every hour by an automatic pump via the intra-peritoneal catheter into the abdomen according to group randomization in order to double blind patients and all personnel involved in the study.
The parameters that would be evaluated are inflammatory markers, postoperative morbidity, pain intensity, consumption of morphine, cognitive function and progression-free survival.

研究组 & 干预措施
Group R
Ropivacaine is instillated through one multi-hole catheter wich would be inserted percutaneously in all patients and tunnelled about 1-2 cm lateral to the abdominal incision and the tip of the catheter placed in the intra-peritoneal cavity. The catheter would not be ligated and fixed in situ intra-peritoneally. Twenty ml of Ropivacaine would be injected subcutaneously along both sides of the incision prior to skin closure. Additionally, 20 ml of Ropivacaine (1mg/mL) would be injected every hour by an automatic pump via the intra-peritoneal catheter into the abdomen.
干预措施: Ropivacaine (Drug)
Group P
Saline is instillated through one multi-hole catheter wich would be inserted percutaneously in all patients and tunnelled about 1-2 cm lateral to the abdominal incision and the tip of the catheter placed in the intra-peritoneal cavity. The catheter would not be ligated and fixed in situ intra-peritoneally. Twenty ml of Saline would be injected subcutaneously along both sides of the incision prior to skin closure. Additionally, 20 ml of Saline would be injected every hour by an automatic pump via the intra-peritoneal catheter into the abdomen.
干预措施: Saline (Drug)
