Objective To study effects of 5 kinds of thermal insulation methods on anabiosis time and postoperative recovery of patients with laparotomy. Methods From January 2015 to December 2015, a total of 150 patients with laparotomy were randomly divided into transfusion + flushing fluid warming+ blanket heating group (Group A), transfusion + body package group(Group B), blanket heating group(Group C), body package group(Group D) and conventional heat preservation group(Group E). Anabiosis time, drainage, surgical site infection and postoperative hospital stay were observed and compared. Results No difference of drainage 1 day after operation, hospital stay and surgical site infection were found(P>0.05); however, conventional heat preservation group had the longest anabiosis time, comparing with transfusion + flushing fluid warming + blanket heating the shortest(P<0.05). Conclusions Implementing active measures on temperature management aiming at controllable factors of hypothermia can shorten anesthesia time and patients′ families waiting time after operation positively and help patients undergo anesthesia recovery period more smoothly.
