“…This analysis was repeated without the nonprewarmed control group to investigate possible differences between the two prewarming periods according to the procedure proposed by Pandit. 13 Data are expressed as mean AE SD or median (IQR [range]), respectively. P less than 0.05 was considered significant.…”

“…To determine the time · pre-warming interaction a repeated measures ANOVA was performed with 'time' as repeated measure and 'pre-warming' as factor followed by the Bonferroni correction. Then, this analysis was repeated without the non-pre-warmed control group to investigate possible differences between the three pre-warming periods [6]. A value of p < 0.05 was considered significant.…”

SummaryThe aim of our study was to evaluate the performance of different durations of active pre-operative skin-surface warming (pre-warming) to prevent peri-operative hypothermia and postoperative shivering. We randomly assigned 200 patients, scheduled for surgery of 30-90 min under general anaesthesia, to receive passive insulation or forced-air skin surface warming for 10, 20 or 30 min. Body temperature was measured at the tympanic membrane. Shivering was graded by visual inspection. There were significant differences in changes of core temperature between the nonpre-warmed group and all the pre-warmed groups (p < 0.00001), but none between the three pre-warmed groups (p = 0.54). Without pre-warming, 38/55 (69%) patients became hypothermic (< 36°C) at the end of anaesthesia, whereas only 7 ⁄ 52 (13%), 3 ⁄ 43 (7%) and 3 ⁄ 50 (6%) patients following 10, 20 or 30 min pre-warming, respectively, became hypothermic (p < 0.001 vs no pre-warming). Shivering was observed in 10 patients without, and in three, three and one patients with pre-warming in the respective groups (p = 0.02). Pre-warming of patients for only 10 or 20 min before general anaesthesia mostly prevents hypothermia and reduces shivering.

“…Categorial variables were tested with chisquared or Fisher's exact tests when appropriate. The effect of time on mean blood pressure and heart rate within the groups was analysed using ANOVA [11]. All statistical analyses were performed with STATVIEW 5.0 (SAS Institute, Inc., Cary, NC, USA).…”

SummaryTracheal intubations with the Airway Scope or the Clarus Video System, a new rigid fibrescope, were compared in 140 patients whose necks were immobilised by cervical collars. The time for intubation, success rate, number of attempts and number of optimisation manoeuvres were assessed. Mean (SD) intubation time was longer with the Airway Scope (30.4 (16.5) s) than with the Clarus Video System (18.9 (15.2) s; p = 0.003) and the median (IQR [range]) number of optimisation manoeuvres was also marginally different; 0 (0-1 [0-2]) with the Airway Scope, 0 (0-0 [0-2]) with the Clarus Video System; p = 0.004. The tracheas of 67 (95.7%) and 66 (94.3%) patients were successfully intubated with the Airway Scope and the Clarus Video System, respectively (p = 1.0). The number of attempts, vital signs and complications were not different between devices. The Clarus Video System was comparable to the Airway Scope in the success rate for tracheal intubation, but provided faster and easier intubations than the Airway Scope in patients with cervical collars.
