Randomized Controlled Trial Clinical Trial
Clonidine premedication prevents preoperative hypokalemia.
To test the hypothesis that clonidine premedication could prevent an increase of plasma epinephrine occurring as a result of anxiety, and a decrease of the serum potassium (K+) levels before the induction of anesthesia. ⋯ Clonidine premedication was effective in preventing hypokalemic episodes occurring before the induction of anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of different lidocaine application methods on postoperative cough and sore throat.
To evaluate the efficacy of various ways of lidocaine application in reducing postoperative cough and sore throat. ⋯ Using lidocaine to inflate the ETT cuff or IV lidocaine at the end of surgery decreases the frequency of postoperative cough and sore throat and would provide better outcome for patients and the physician.

Randomized Controlled Trial Comparative Study Clinical Trial
Low-dose dexamethasone reduces nausea and vomiting after epidural morphine: a comparison of metoclopramide with saline.
To compare the efficacy of a low dose of dexamethasone (5 mg) with metoclopramide 10 mg and saline in preventing nausea and vomiting after epidural morphine in posthysterectomy analgesia. ⋯ Dexamethasone 5 mg was more effective than metoclopramide or saline in the prevention of nausea and vomiting associated with epidural morphine for postoperative analgesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized comparison of isoflurane and sevoflurane for laparoscopic gastric banding in morbidly obese patients.
To compare the efficacy and recovery profile of sevoflurane and isoflurane as the main anesthetics for morbidly obese patients. ⋯ Sevoflurane provides a safe and effective intraoperative control of cardiovascular homeostasis in morbidly obese patients undergoing laparoscopic gastric banding, with the advantage of a faster recovery and earlier discharge from the postanesthesia care unit than isoflurane.

Randomized Controlled Trial Clinical Trial
The effect of transdermal nitroglycerin on spinal S(+)-ketamine antinociception following orthopedic surgery.
To determine whether combination of transdermal nitroglycerine (a nitric oxide generator) would enhance analgesia from epidural S(+)-ketamine (a N-methyl-D-aspartate antagonist) in patients undergoing orthopedic surgery with combined spinal anesthesia. ⋯ Epidural S(+)-ketamine resulted in antinociception, which was enhanced by transdermal nitroglycerin.
