ObjectiveTo evaluate the effect of different temperature protection measures on the quality of recovery in elderly patients with colorectal cancer surgery.

MethodsA total of 120 elderly patients scheduled for radical resection of colorectal cancer were selected and divided into conventional group(group C), infusion heating group(group Y), heating blanket heating group(group T) and infusion heating combined with heating blanket heating group(group YT)(30 cases in each group) by random number table method.The patient′s abdominal cavity was routinely rinsed with warm 0.9% sodium chloride solution.Group C did not receive special treatment, group Y was heated with 37 ℃ constant temperature heating treatment of the infusion warmer for the infusion pipeline on the basis of group C, group T began to apply heating blanket at 30 min after entering the operation room to maintain the patient′s body temperature at 36-37 ℃, and group YT was heated with infusion warmer and heating blanket.The general information of the patients was collected.The recovery time of spontaneous breathing, postoperative eye opening time, extubation time, stay time in the resuscitation room and occurrence of agitation in recovery period were recorded.MMSE scores were evaluated before operation, 1, 3 and 7 days after operation, and the occurrence of postoperative delirium was recorded.

ResultsThe intraoperative body temperature in group T and group YT was significantly higher than that in group C and group Y(P < 0.01).The recovery time of spontaneous breathing, postoperative eye opening time, extubation time, stay time in the resuscitation room and incidence of agitation in recovery period in group T and group YT were significantly lower than those in group C and group Y(P < 0.01), and there was no significant difference in recovery time of spontaneous breathing, postoperative eye opening time, extubation time, stay time in the resuscitation room and incidence of agitation in recovery period between group Y and group C(P>0.05).The MMSE score in group C and group Y on the first day after operation was significantly lower than that before operation(P < 0.01), and there was no significant difference in perioperative MMSE score between group T and group YT(P>0.05).The incidence of postoperative delirium in group T and group YT was lower than that in group C and group Y(P < 0.05), and there was no significant difference in the incidence of postoperative delirium between group Y and group C (P>0.05).

ConclusionsHeating with heating blanket alone or combined with infusion heating can effectively shorten the postoperative recovery time, reduce the incidence of postoperative cognitive dysfunction and delirium, improve the quality of postoperative recovery, which is conducive to early postoperative rehabilitation.
