Randomized Controlled Trial
A prospective randomized study for postoperative pain relief of lower extremity fractures: efficacy of intrathecal morphine administration.
Systemic opioids are known to be effective for controlling postoperative pain. Intrathecal morphine administration can be performed in a simple manner concurrently with spinal anesthesia. The purpose of this study was to investigate the efficacy of intrathecal morphine administration for the postoperative analgesia of lower extremity fractures. ⋯ The time of first request of the control group was shorter than that of the morphine group (p < 0.001). Side effects were seen more frequently in the morphine group though there was no significant difference. Although the use of morphine requires appropriate postoperative care, an intrathecal morphine injection can be an attractive analgesic for the postoperative pain of lower extremity fractures.

Randomized Controlled Trial Clinical Trial
Effect of oral clonidine premedication on hemodynamic response during sedated nasal fiberoptic intubation.
Although oral clonidine premedication is known to reduce the hemodynamic response under general anesthesia, effects of the hemodynamic response during sedated fiberoptic nasal intubation have not yet been examined. Our aim was to compare the effects of clonidine premedication on hemodynamic responses with those of atropine and hydroxyzine premedication during sedated fiberoptic nasal intubation. Thirty adult patients were randomly assigned to one of two groups: Group 1 patients (n = 15) were premedicated with atropine sulfate (0.01 mg/kg) and hydroxyzine hydrochloride (1mg/kg) intramuscularly, and group 2 patients (n = 15) were premedicated with clonidine (5 micrograms/kg) orally. ⋯ But the oral clonidine premedication (Group 2) blunted hemodynamic changes during the fiberoptic intubation. No profound hypotension or marked bradycardia was noted in group 2. We concluded that the oral clonidine premedication might contribute to hemodynamic stability during sedated fiberoptic nasal intubation.
