Randomized Controlled Trial Clinical Trial
Intrathecal lidocaine and sufentanil shorten postoperative recovery after outpatient rectal surgery.
A short recovery time for same day surgery is important to the patient and the hospital. A prospective, randomized, double-blinded study in the postanesthetic care unit was designed to compare the recovery time from spinal anesthesia with low-dose intrathecal (IT) lidocaine and sufentanil to that with IT lidocaine alone. The incidence of adverse effects was also assessed. ⋯ IT lidocaine (15 mg) and sufentanil resulted in a shorter time to ambulation compared to IT lidocaine (50 mg) alone and provided excellent anesthesia despite its disadvantage of pruritus.

Randomized Controlled Trial Clinical Trial
Prophylactic ondansetron does not reduce the incidence of itching induced by intrathecal sufentanil.
Postoperative itching after intrathecal (IT) narcotics may be a difficult and important problem for both the anesthesiologist and the patient in the postanesthetic care unit. Since some studies have reported success in preventing itching with ondansetron, we designed a prospective, randomized, double-blinded, and controlled study to test whether prophylactic iv ondansetron effectively reduces the incidence of IT sufentanil-induced pruritus. ⋯ There are contradictory findings in the literature regarding the effectiveness of ondansetron in preventing narcotic-induced itching. Although some studies have indicated that ondansetron could prevent this side effect of IT narcotics, a recent report suggested that ondansetron is not effective in preventing narcotic-induced itching (sufentanil-morphine) after a Cesarean section. In the present study we obtained similar, negative results.

Randomized Controlled Trial Clinical Trial
Neuromuscular blockade does not change the incidence or severity of pharyngolaryngeal discomfort after LMA anesthesia.
Positive pressure ventilation using a laryngeal mask airway (LMA) has gained increased popularity. This study examined the influence of neuromuscular blockade on the incidence and severity of pharyngolaryngeal discomfort after positive pressure ventilation using a LMA. ⋯ Neuromuscular blockade does not influence the ease or rate of success of LMA insertion nor the incidence and severity of pharyngolaryngeal discomfort after positive pressure ventilation using a LMA.

Randomized Controlled Trial Comparative Study Clinical Trial
Oral tandospirone and clonidine provide similar relief of preoperative anxiety.
To compare oral tandospirone with oral clonidine in terms of preoperative anxiolysis. ⋯ Oral tandospirone was equivalent to oral clonidine in terms of reduction in preoperative anxiety.

Randomized Controlled Trial Clinical Trial
A background infusion of morphine enhances patient-controlled analgesia after cardiac surgery.
We compared the efficacy of patient-controlled analgesia (PCA), with or without a background infusion of morphine, on postoperative pain relief in patients extubated in the operating room after coronary artery bypass grafting (CABG) surgery. ⋯ Morphine PCA effectively controlled postoperative pain after cardiac surgery. The addition of a background infusion of morphine enhanced analgesia and increased morphine consumption.
