Evaluation of the application of self-made lithotomy heating mask in radical resection of rectal cancer / 中国实用护理杂志

ABSTRACT

Objective:To evaluate the effect of self-made lithotomy heating mask on intraoperative and postoperative body temperature and short-term postoperative outcome indicators in patients undergoing radical resection of rectal cancer.Methods:Using the method of quasi experimental research design, 100 patients with open rectal cancer in Ningbo Huamei Hospital of the University of Chinese Academy of Sciences from February to July 2021 were selected as the research objects. The patients were divided into experimental group and control group with 50 cases in each group. The control group was kept warm by routine methods, and the experimental group was kept warm by self-made lithotomy heating hood. The changes of core temperature at different time points before, during and after operation were compared between the two groups. The incidence of accidental hypothermia and shivering, the recovery time of anesthesia, and the incidence of various complications within 48 hours after operation were compared between the two groups after operation from the beginning of the operation to 6 hours after returning to the ward.Results:From 30 minutes after anesthesia to 3 hours after entering the ward, the core temperatures of the experimental group at 10 time points were higher than that of the control group, and the differences were statistically significant ( t values were 3.48-37.30, all P<0.01). From the beginning of surgery to 6 h after returning to the ward, the incidence of perioperative accidental hypothermia in the experimental group was 2% (1/50), lower than 24% (12/50) in the control group, and the difference was statistically significant ( χ2=11.06, P<0.05) . The number of cases of shivering in the experimental group was 10, lower than that in the control group of 22, the difference was statistically significant ( χ2=6.62, P<0.05) . The recovery time, extubation time and stay time in anesthesia recovery room of the experimental group were (8.44 ± 2.83), (13.05 ± 4.72), (74.51 ± 11.82) min, which were shorter than those of the control group (15.35 ± 2.09), (17.62 ± 3.28), (89.14 ± 9.19) min, and the difference was statistically significant ( t=-13.89, -5.62, -6.91, all P<0.01). The number of cases of agitation, delirium and nausea and vomiting in the experimental group was 3, 1 and 2 respectively, which was lower than 13, 7 and 8 in the control group, and the difference were statistically significant ( χ2=7.44, 4.89, 4.00, all P<0.05). There was no significant difference in the incidence of adverse cardiac events between the two groups ( P>0.05). Conclusions:The application of self-made lithotomy heating mask in open rectal cancer surgery can effectively improve the risk of hypothermia at different time points during and after surgery, reduce the incidence of shivering, restlessness, postoperative nausea, vomiting and delirium, shorten the time of awakening and extubation, and prevent postoperative complications. It has practical value in clinic.
