Randomized Controlled TrialOndansetron and meperidine prevent postoperative shivering after general anesthesia.
Postoperative shivering is one of the common problems following general anesthesia and may lead to multiple complications. The aim of this study was to examine the preventive effects of Ondansetron and Meperidine on postoperative shivering. ⋯ Ondansetron can effectively reduce post operative shivering.

Randomized Controlled TrialThe effect of the addition of lornoxicam (xefocam) intrarticularly on the WOMAC Scale in patients undergoing arthroscopic anterior cruciate ligament reconstruction.
Effective pain relief is important after diagnostic and therapeutic arthroscopic knee surgery to permit early discharge and improve comfort and mobility at home. We compared the intraarticular analgesic effects of ropivacaine and morphine with or without Xefocam and the need for rescue i.v. morphine at rest and during movement in patients undergoing anterior cruciate ligament reconstruction under spinal anesthesia. Anterior cruciate ligament reconstruction (ACLR) is associated with moderate to severe postoperative pain. ⋯ Forty five patients undergoing anterior cruciate ligament reconstruction (ACLR) under spinal anesthesia were enrolled in this study. Patients were divided into three equal groups (15 each); the C group received saline. The RM group received 0.25% ropivacaine and morphine 0.2 mg/mL; the RMX group received 0.25% ropivacaine, morphine 0.2 mg/mL and Xefocam 0.8 mg/mL postoperatively they received intraarticular patient-controlled analgesia. The study drug was given in a volume of 10-mL bolus and a 60-min lockout interval. If needed, rescue morphine 2 mg was self-administered i.v. with 10-min lockout intervals. Pain scores and patient satisfaction were assessed at rest and during movement. There were significant differences among the groups in pain scores and patient satisfaction and in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Classification. Daily morphine consumption was significantly smaller in the RMX group (7 +/- 6 mg) compared with the RM group (23 +/- 20 mg; P = 0.002) and in both groups compared with control (46 +/- 21 mg; P < 0.001). We conclude that intraarticular patient-controlled regional analgesia provides effective pain relief after anterior cruciate ligament reconstruction. The combination of intraarticular ropivacaine, morphine, and xefocam was superior to control or to a combination of ropivacaine and morphine.

Randomized Controlled TrialPreemptive peritonsillar ketamine infiltration: postoperative analgesic efficacy versus meperidine.
The current study was planned to assess post-tonsillectomy analgesic efficacy of pre-emptive peritonsillar ketamine infiltration with or without bupivacaine in comparison to meperidine alone or in combination with bupivacaine. ⋯ Peritonsillar injection of a combination of bupivacaine and ketamine provided efficient postoperative analgesia after adenotonsillectomy and achieved higher parents' satisfaction for the outcome of surgery. The used drugs' combination and volume could be recommended as a routine preemptive analgesic policy for children assigned for adenotonsillectomy.

Randomized Controlled TrialThe effect of low dose rocuronium on intraocular pressure in laryngeal mask airway usage.
We have compared the effect of low dose rocuronium on intraocular pressure (IOP) in larygeal mask airway usage during induction of anesthesia using propofol and fentanyl, in a randomized, double-blind study. ⋯ Although there have been reports that LMA insertion minimally increases IOP, in our study, by using low dose rocuronium and LMA there was a decrease in IOP.

Randomized Controlled TrialHemodynamic response to tracheal intubation via direct laryngoscopy and intubating laryngeal mask airway (ILMA) in patients undergoing coronary artery bypass graft (CABG).
A marked stress response including hypertension, tachycardia, arrhythmias and an increase in intracranial pressure often follows direct laryngoscopy. This response can be harmful specially in patients with underlying cardiac disease. The intubating laryngeal mask airway (ILMA)--a new modified laryngeal mask airway--has been introduced that facilitates tracheal intubation without using laryngoscopy. Oropharyngeal stimulation-proposed as the probable cause of stress response--have been shown to be attenuated in ILMA. We conducted this study to evaluate the stress response following two techniques in patients undergoing coronary artery surgery which are most likely to benefit from decreased hemodynamic changes during intubation. ⋯ Finally we could hardly ascertain if intubation with ILMA is a prefered method in patients with high cardiac risk or not. But it seems that ILMA does not have much greater benefit over conventional DL in patients undergoing coronary artery by-pass grafting.
