Randomized Controlled Trial Comparative StudyThe effect of deliberate hypercapnia and hypocapnia on intraoperative blood loss and quality of surgical field during functional endoscopic sinus surgery.
Anesthetic management during functional endoscopic sinus surgery is aimed at minimizing bleeding and establishing a near-perfect surgical field. We investigated whether deliberate intraoperative hypercapnia and hypocapnia may affect blood loss and quality of surgical field through a proposed modulating effect of different carbon dioxide (CO2) tension levels on nasal vasculature. ⋯ CO2 management during functional endoscopic sinus surgery does not influence operating conditions or blood loss.

Randomized Controlled Trial Comparative StudyThe clinical impact of preoperative melatonin on postoperative outcomes in patients undergoing abdominal hysterectomy.
Melatonin has sedative, analgesic, antiinflammatory, antioxidative, and chronobiotic effects. We determined the impact of oral melatonin premedication on anxiolysis, analgesia, and the potency of the rest/activity circadian rhythm. ⋯ This finding suggested that preoperative melatonin produced clinically relevant anxiolytic and analgesic effects, especially in the first 24 postoperative hours. Also, it improved the recovery of the potency of the rest/activity circadian rhythm.

Randomized Controlled Trial Comparative StudyAn evaluation of the efficacy of gabapentin for prevention of catheter-related bladder discomfort: a prospective, randomized, placebo-controlled, double-blind study.
Catheter-related bladder discomfort (CRBD) secondary to catheterization of urinary bladder is distressing. In the present study, we evaluated gabapentin for preventing CRBD. ⋯ Gabapentin (600 mg) administered orally 1 h before surgery reduced the incidence and severity of CRBD, postoperative pain, number of patients requiring fentanyl and postoperative total fentanyl requirement.

Randomized Controlled Trial Comparative StudyIntraoperative forced air-warming during cesarean delivery under spinal anesthesia does not prevent maternal hypothermia.
Prewarming and intraoperative warming with forced air-warming systems prevent perioperative hypothermia and shivering in patients undergoing elective cesarean delivery with epidural anesthesia. We tested the hypothesis that intraoperative lower body forced air-warming prevents hypothermia in patients undergoing elective cesarean delivery with spinal anesthesia. ⋯ We conclude that intraoperative lower body forced air-warming does not prevent intraoperative hypothermia or shivering in women undergoing elective cesarean delivery with spinal anesthesia.

Randomized Controlled Trial Comparative StudyLow-dose intravenous midazolam reduces etomidate-induced myoclonus: a prospective, randomized study in patients undergoing elective cardioversion.
Myoclonic movements are a common problem in unpremedicated patients during induction of anesthesia with etomidate. ⋯ IV midazolam 0.015 mg/kg administered 90 s before induction of anesthesia with etomidate is effective in reducing myoclonic movements and does not prolong recovery in unpremedicated patients after short procedures.
