Objective:To explore the prevention effect of forced-air warming to the upper body on hypothermia during thoracoscopic surgery in the lateral decubitus position.Methods:A total of 82 patients undergoing thoracoscopic surgery in the lateral position from December 2018 to July 2019 in Jiangsu People's Hospital, the First Affiliated Hospital of Nanjing Medical University were divided into upper body group and lower body group according to the random number table method. Each group was 41 cases. Patients received forced-air warming on the upper body or lower body in the upper body group and lower body group, respectively. The bladder temperature was measured as core temperature at operation room, intubation, start of the surgery, 30 min after surgery, 60 min after surgery, 90 min after surgery, 120 min after surgery, end of the surgery. The incidence of intraoperative hypothermia, perioperative adverse complications and vital index at leaving the room were compared between upper body group and lower body group.Results:The core temperature at start of the surgery, 30 min after surgery, 60 min after surgery, 90 min after surgery were (36.70±0.12), (36.65±0.16), (36.30±0.18), (36.32±0.19) ℃ in the upper body group, and (36.42±0.13), (36.32±0.17), (36.17±0.14), (36.21±0.15)℃ in the lower body group, the differences were statistically significant ( t values were 2.743-10.362, P<0.05). However, there was no statistically significant in the core temperature at other time points between the two groups ( P>0.05). The incidences of intraoperative hypothermia and perioperative shiver were 12.2%(5/41), 4.9%(2/41) in the upper body group, and 31.7%(13/41), 21.9%(9/41) in the lower body group, the differences were statistically significant ( χ2 values were 4.556, 5.145, P<0.05). There was no statistically significant in the other perioperative adverse complications and vital index at leaving the room between two groups ( P>0.05). Conclusions:Forced-air warming was more effective on the upper body in resistive body core temperature. Besides, the incidences of hypothermia and shiver on the upper body is lower.

Objective To study the risk factors for recurrence in glottic cancer at Tis,T1 and T2 stage after CO2 laser endoscopic resection.Methods We conducted a retrospective analysis of 180 Tis,T1 and T2 glottic cancer cases treated by CO2 laser surgery.Of the total cases,the Tis stage lesion was found in 22 cases,the T1a in 90,the T1b in 32 and the T2 in 36 cases.Tumor recurrence was set as the time-related endpoint.The recurrence factors were analyzed by univariate and multivariate analysis,including age,gender,T classification,type of cordectomy,tumorgrading,motility of vocal fold and the possible anteior commissure.Results There was a significant statistical difference between the recurrence rate and T classification,and the type of cordectomy(P＜0.05).The recurrence rates of Tis,T1a,T1b and T2 were 9.1％,13.3％,18.8％ and 38.9％,respectively.In type-Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ of cordectomy,the recurrence rates were 0,3.57％,15.0％,19.60％ and 36.84％.Conclusion The recurrence rate is closely associated with T classification and the type of cordectomy.With the higher T classification and the type of cordectomy,the recurrence rate is dramatically higher.
