Randomized Controlled Trial
Impact of time interval between remifentanil and propofol on propofol injection pain.
To determine the most effective time interval between remifentanil and propofol (TimeRP) for the prevention of propofol injection pain in association with remifentanil dosage. ⋯ The efficacy of remifentanil pretreatment for preventing propofol injection pain can be influenced by the time interval between remifentanil and propofol as well as the remifentanil dose.

Randomized Controlled Trial Comparative Study
Magnesium sulfate or diltiazem as adjuvants to total intravenous anesthesia to reduce blood loss in functional endoscopic sinus surgery.
This study was designed to know whether addition of magnesium sulfate (MgSO4) or diltiazem to total intravenous anesthesia (TIVA) (propofol) aided reduction in blood loss during functional endoscopic sinus surgery (FESS). The secondary outcomes measured were surgeon's assessment of the surgical field and hemodynamics. ⋯ It was concluded that the addition of both MgSO4 and diltiazem to TIVA propofol results in significant reduction in blood loss and significant improvement in the quality of surgical field during FESS without causing any adverse effects on the hemodynamics or on the recovery from anesthesia. The surgical field in the MgSO4 group was significantly better than that in the diltiazem group (P=.04).

Randomized Controlled Trial
Low-dose butorphanol alleviates remifetanil-induced hyperalgesia in patients undergoing laparoscopic cholecystectomy.
To evaluate the effects of low-dose butorphanol on hyperalgesia induced by high-dose remifetanil in patients undergoing laparoscopic cholecystectomy. ⋯ A high dose of remifentanil induces postoperative hyperalgesia, which could be prevented by a continuous intravenous administration of a low dose of butorphanol.

Randomized Controlled Trial Comparative Study
Intraocular pressure changes: the McGrath video laryngoscope vs the Macintosh laryngoscope; a randomized trial.
To determine the effects of the McGrath Series 5 video laryngoscope on intraocular pressure (IOP) during laryngoscopy. ⋯ The McGrath Series 5 video laryngoscope may provide a lower IOP level compared to the Macintosh laryngoscope in an otherwise healthy, young patient population.

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.
