Effects of in-house made heat preservation socks on body temperature maintenance in elderly patients undergoing spinal surgery / 中华老年医学杂志

ABSTRACT

Objective:To examine the effects of in-house made heat preservation socks on body temperature maintenance in elderly patients undergoing posterior approach spinal surgery.Methods:This was a randomized, controlled trial.A total of 84 patients aged 65-75 years treated with posterior approach spinal surgery under general anesthesia were enrolled.Patients were randomly divided into two groups the experimental group(n=42)and the control group(n=42). The two groups were treated with the same anesthesia procedure.The control group was given routine temperature management, while the experimental group used in-house made heat preservation socks in addition to routine temperature management during the entire surgical process.The anal temperature of patients was dynamically monitored with a disposable body temperature probe, and body temperature, heart rate, mean arterial pressure and oxygen saturation were recorded at the time of anesthesia induction and intubation(T 0), skin incision(T 1), 1 hour into surgery(T 2), 2 hours into surgery(T 3), the end of surgery(T 4), arrival at the post-anesthesia care unit(T 5), immediately after extubation(T 6)and 1 hour after extubation(T 7). The occurrence of intraoperative body temperature lower than 36℃, postoperative extubation time, incidence of shivering, postoperative incision infection rate and average length of stay were recorded.Changes in C-reactive protein and procalctonin levels were recorded. Results:There was no significant difference in sex composition, age, height, weight, body mass index and operative time between the two groups(all P>0.05). From T 2 to T 7, the body temperature of the experimental group was higher than that of the control group[T 2 (36.5±0.5)℃ vs.(36.3±0.3)℃, (36.6±0.6)℃ vs.(36.2±0.4)℃, (36.6±0.6)℃ vs.(36.2±0.4)℃, (36.6±0.6)℃ vs.(36.2±0.4)℃, (36.6±0.6)℃ vs.(36.2±0.4)℃, (36.6±0.5)℃ vs.(36.2±0.3)℃, t=2.229, 3.514, 3.823, 3.790, 3.722, 4.408, P=0.029, 0.001, 0.001, 0.001, 0.001, 0.000]. The incidence of intraoperative body temperature lower than 36 ℃ in the control group was higher than that in the experimental group(47.6% vs.21.4%, χ2=6.372, P=0.012). The incidence of postoperative shivering in the experimental group was lower than that in the control group(21.4% vs.59.5%, χ2=12.649, P<0.001). There was no significant difference between the two groups in postoperative incision infection rate, average length of stay and postoperative inflammatory infection indicators(all P>0.05). Conclusions:For elderly patients undergoing posterior spinal surgery, the in-house made heat preservation socks have favorable effects on body temperature maintenance and help reduce the occurrence of hypothermia and postoperative shivering.
