Postoperative analgesia with tramadol and indomethacin for diagnostic curettage and early termination of pregnancy.

Background: The postoperative analgesic effects of rectal indomethacin and tramadol were compared in patients undergoing elective termination of first trimester pregnancy and diagnostic dilatation and curettage.

Methods: Eighty-one American Society of Anesthesiologists class I and II women undergoing first trimester termination of pregnancy or diagnostic dilation and curettage were randomly allocated to receive rectal suppositories of either tramadol 100 mg (n=41) or indomethacin 100 mg (n=40) 90 min before induction of anesthesia. Pain scores and side effects were evaluated until discharge.

The effect of intermittent versus continuous bladder catheterization on labor duration and postpartum urinary retention and infection: a randomized trial.

Study Objective: To assess the effect of intermittent versus continuous bladder catheterization on labor duration and local anesthetic consumption.

Design: Randomized, controlled, prospective, single-blind trial.

Setting: University-affiliated hospital.

Gastroesophageal regurgitation during anesthesia and controlled ventilation with six airway devices.

Study Objective: To investigate the frequency of gastroesophageal regurgitation and respiratory mechanics during positive pressure ventilation using 5 supraglottic devices or an endotracheal tube (ETT).

Design: Prospective, randomized study.

Setting: Operating rooms in a university-affiliated hospital.

Predistention of the epidural space before catheter insertion reduces the incidence of intravascular epidural catheter insertion.

Background: Accidental cannulation of an epidural vein is a common complication associated with epidural anesthesia or analgesia. On the basis of a pilot study and previous reports, we tested the hypothesis that predistention of the epidural space with saline before epidural catheterization would ease catheter insertion and decrease the incidence of this complication.

Methods: Two-hundred-three laboring women were randomly assigned to receive an epidural with loss of resistance technique with 2 mL (nondistention) or 5 mL saline (distention).

Proper insertion depth of endotracheal tubes in adults by topographic landmarks measurements.

Study Objective: To evaluate a new method of endotracheal tube (ETT) positioning relative to carina, based on external topographic landmarks.

Design: Prospective, randomized, crossover study.

Setting: Operating room, university hospital.
