Randomized Controlled Trial Clinical Trial
Effect of postoperative skin-surface warming on oxygen consumption and the shivering threshold.
Cutaneous warming is reportedly an effective treatment for shivering during epidural and after general anaesthesia. We quantified the efficacy of cutaneous warming as a treatment for shivering. Unwarmed surgical patients (final intra-operative core temperatures approximately 35 degrees C) were randomly assigned to be covered with a blanket (n = 9) or full-body forced-air cover (n = 9). ⋯ However, the duration of shivering was similar in the unwarmed (37 min (11)) and active warming (36 min (10)) groups. Core temperature contributed about four times as much as skin temperature to control of shivering. Cutaneous warming improved thermal comfort and reduced metabolic stress in postoperative patients, but did not quickly obliterate shivering.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of deep vs. awake removal of the laryngeal mask airway in paediatric dental daycase surgery. A randomised controlled trial.
Dental anaesthesia provides a potential conflict between anaesthetist and surgeon because of the shared airway. The laryngeal mask airway (LMA) has helped to improve airway control for these procedures, but there is little evidence for best practice on the timing of their removal after airway surgery in the paediatric population. ⋯ It was also found that the deep group had a higher incidence of patients with SpO2 < 95% (p = 0.003) and of patients who coughed (p = 0.003). We conclude that the LMA should be taken out awake in these patients.
