Abstract:Objective To observe the application effect of continuous wound infusion of Ropivacaine combined with intravenous Parecoxib Sodium after right hemicolectomy. Methods Sixty patients undergoing right hemicolectomy were enrolled in our hospital from February 2014 to October 2015 and randomly divided into observation group (n = 30) and control group (n = 30). The observation group received analgesia with continuous incision infusion of Ropivacaine combined with intravenous Parecoxib Sodium, the control group merely received analgesia with intravenous Parecoxib Sodium. The numerical rating scales (NRS) of pain at 6, 20, 32, 44 and 56 h after operation, body temperature on postoperative day (POD)1, POD2 and POD3, white blood cell count and neutrophilic percentage on POD1 and POD 3, time of the first flatus, hospital stay after operation, and the incidences of incision complications and total complications were compared between the two groups. Results NRS of pain in the observation group was significantly lower than that in the control group at 6, 20, 32, 44 and 56 h after operation (P < 0.05). Body temperature, white blood cell count, neutrophilic percentage and time of hospital stay were similar in the two groups (P > 0.05), but the number of patients requiring remedial analgesia was larger than that in the control group (P < 0.05), the time of the first flatus was significantly earlier than that in the control group (P < 0.05). The incidence of incison complications was similar in the two groups (P > 0.05), but the incidences of nausea and total complications were significantly lower than those in the control group (P < 0.05). Conclusions Compared to solely intravenous Parecoxib Sodium, continuous incision infusion of Ropivacaine combined with intravenous Parecoxib Sodium could effectively reduce pain after right hemicolectomy, promote the recovery of gastrointestinal function and decrease the occurrence of nause and total complications after operation.
