Randomized Controlled Trial Comparative Study
Nerve stimulator guided pudendal nerve block versus general anesthesia for hemorrhoidectomy.
A randomized clinical trial was undertaken to test the hypothesis that patients receiving a nerve stimulator guided pudendal nerve block for hemorrhoidectomy would experience more effective and prolonged postoperative analgesia and shorter hospital stay compared to patients receiving general anesthesia. ⋯ Nerve stimulator guided pudendal nerve block is associated with reduced postoperative pain, shortened hospital stay, and earlier return to normal activity compared to general anesthesia for hemorrhoidectomy.

Randomized Controlled Trial
Recovery from vecuronium is delayed in patients with hypercholesterolemia.
To examine the effects of hypercholesterolemia with respect to onset time and recovery from vecuronium-induced neuromuscular block. ⋯ Recovery from vecuronium-induced neuromuscular block is delayed in patients with hypercholesterolemia.

Randomized Controlled Trial
The effect of epidural needle type on postdural puncture headache: a randomized trial.
A prospective, randomized trial in labouring parturients was undertaken to assess whether the 18G Special Sprotte epidural needle is associated with a lower incidence of accidental dural puncture (ADP) in comparison with the 17G Tuohy needle. A secondary purpose was to determine if the incidence of postdural puncture headache (PDPH ) differed between groups when ADP occurred. ⋯ The incidence of ADP was not reduced with the Special Sprotte epidural needle in comparison with the Tuohy needle, but PDPH after ADP occurred less frequently in the Sprotte group.

Randomized Controlled Trial Comparative Study
Lower flange modification improves performance of the Macintosh, but not the Miller laryngoscope blade.
In order to minimize the potential for dental damage and to improve laryngeal visualization during tracheal intubation, two commonly used laryngoscope blades were modified and compared in a clinical setting: the Miller laryngoscope blade and the Macintosh laryngoscope blade. Modified versions of both laryngoscope blades with a lowered heel (Callander modification) at the proximal end of the blade were compared to standard blades. ⋯ A reduction of the proximal flange of a Miller blade decreases the blade's effectiveness for laryngeal visualization, whereas a similar modification of a Macintosh blade increases blade-tooth distance, decreases the number of blade-tooth contacts and provides a better laryngeal view.

Randomized Controlled Trial Comparative Study
Laparoscopy for colectomy accelerates restoration of bowel function when using patient controlled analgesia.
A standardized care plan incorporating patient-controlled analgesia with iv morphine and a non-accelerated feeding schedule following colectomy was used to compare return of bowel function and hospital discharge times following surgery done by laparoscopy or laparotomy ⋯ When patient-controlled analgesia with morphine and a traditional perioperative program are used, a laparoscopic approach to colon surgery promotes earlier restoration of bowel function and more rapid hospital discharge in comparison to resection by laparotomy.
