Abstract:
Objective:To evaluate the effect of sex factors on rewarming in patients with mild hypothermia undergoing lithotripsy for urolithiasis.Methods:In this prospective study, 100 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-60 yr, with a body mass index of 18-30 kg/m 2, scheduled for elective lithotripsy for urolithiasis, were divided into 2 groups ( n=50 each) based on sex: male group (group M) and female group (group F). The rewarming measures were as follows: the room was preheated, maintaining a constant temperature of 22-24 ℃, all the patients were covered with medical heating blanket under their bodies, and the inflatable heating apparatus was placed on the surface quilt, and the air supply was placed near the lower limbs of the patients. The parameters were set as follows: temperature 40 ℃, strong wind. If the patients complained of heat, the temperature parameter settings were changed, and the quilt was removed when necessary. If the patients complained of cold, blood transfusion and infusion heating instrument were added, medical heating blanket was turned on, or an anther quilt was used. Body temperature and the number of patients with successful rewarming were recorded on admission to post-anesthesia care unit (T 0) and at 10, 30, 45 and 60 min after rewarming (T 1-4), and at 1, 3 and 5 h after returning to the ward (T 5-7). The comfort scores were assessed while measuring body temperature at T 0 and T 4, and the occurrence of shivering, hypertension, hypotension and arrhythmias was observed. Results:Compared with group F, the body temperature was significantly increased at T 3 and T 4, the success rate of rewarming and incidence of shivering were increased at T 3 ( P<0.05), and no significant change was found in the incidence of hypertension, hypotension and arrhythmias in group M ( P<0.05). Conclusions:Sex factors affect rewarming outcomes in patients with mild hypothermia undergoing lithotripsy for urolithiasis. Females exhibit a slower rewarming rate and less shivering than males.
