Randomized Controlled Trial Multicenter Study
Active perioperative patient warming using a self-warming blanket (BARRIER EasyWarm) is superior to passive thermal insulation: a multinational, multicenter, randomized trial.
Incidence of inadvertent perioperative hypothermia is still high; therefore, present guidelines advocate "prewarming" for its prevention. Prewarming means preoperative patient skin warming, which minimizes redistribution hypothermia caused by induction of anesthesia. In this study, we compared the new self-warming BARRIER EasyWarm blanket with passive thermal insulation regarding mean perioperative patient core body temperature. ⋯ Perioperative use of the new self-warming blanket improves mean perioperative core body temperature, reduces the incidence of inadvertent perioperative hypothermia, and improves patients' thermal comfort during elective adult surgery.

Myotonic dystrophy (DM), though rare, can significantly complicate anesthesia due to muscular and extra-muscular involvement. When this condition is compounded by a pheochromocytoma, anesthetizing such patients becomes extra challenging. ⋯ The conduct of anesthesia and recovery of this patient is described. Our experience suggests that anesthetizing these patients though challenging can be safely managed with relaxant general anesthesia and epidural analgesia with meticulous care pre, intra and post-surgical intervention.

Randomized Controlled Trial Comparative Study
A comparison of prophylactic use of meperidine, meperidine plus dexamethasone, and ketamine plus midazolam for preventing of shivering during spinal anesthesia: a randomized, double-blind, placebo-controlled study.
The aim of this study is to compare the efficacy of combination of meperidine and dexamethasone with that of placebo, meperidine alone, and the combination of ketamine and midazolam in preventing shivering during spinal anesthesia. ⋯ Prophylactic use of meperidine 0.2mg/kg plus dexamethasone 0.1mg/kg was more effective than meperidine 0.4mg/kg as a sole agent or the combination of ketamine 0.25mg/kg and midazolam 37.5μg/kg in preventing shivering resulting from spinal anesthesia.

Randomized Controlled Trial Comparative Study
Effects of music on sedation depth and sedative use during pediatric dental procedures.
The study aimed to investigate the effects of listening to music or providing sound isolation on the depth of sedation and need for sedatives in pediatric dental patients. ⋯ Listening to music or providing sound isolation during pediatric dental interventions did not alter the sedation level, amount of medication, and hemodynamic variables significantly. This result might be due to the deep sedation levels reached during the procedures. However, listening to music and providing sound isolation might have contributed in shortening the postoperative recovery duration of the patients.

Recovery from anesthesia may be complicated with development of severe panic symptoms and anxiety. Preexisting anxiety disorder has been reported as a risk factor for development of these symptoms. We aimed to examine the frequency of emergence delirium (EDL) among veterans diagnosed with posttraumatic stress disorders (PTSDs). ⋯ Posttraumatic stress disorder independently predicted the frequency of EDL even after correcting for preexisting depression and anxiety disorders. A relatively longer duration of PACU stay in PTSD patients may reflect raised awareness of the health care workers about this debilitating mental disorder.
