Abstract:
Between January 2011 and December 2011,86 patients undergoing operation for anorectal disease were randomized in a double-blind manner to receive a mixed injection of methylene blue,ropivacaine and sodium chloride (observation group,n =43) or traditional analgesic methods (control group,n =43).Patients in observation group had less visual analog scale (VAS) scores of pain at 6-48 h postoperation than control group (P ＜0.05).The scores had no significant difference at 72 h postoperation between two groups (P ＞ 0.05).The total postoperative complications (8,19％) and hospitalization duration [(5.3 ± 2.2) days] in observation group were significantly less than those [15,35 ％ and (6.4 ±1.7) days] in control group (P ＜ 0.05).A mixed injection of methylene blue and ropivacaine intraoperatively can relieve the postoperative pain of patients with anorectal disease and reduce the incidence of postoperative complications and the duration of hospitalization.
