Delayed side effects of droperidol after ambulatory general anesthesia.
The incidence of postoperative effects of droperidol, in the hospital and at home the following night, after general anesthesia for minor outpatient procedures was evaluated in two groups of 50 patients each. Anesthetic techniques were identical except for the presence or absence of 1.25 mg of IV droperidol. ⋯ No patient not receiving droperidol had these reactions. It is suggested that the routine use of droperidol in all outpatients receiving general anesthesia may not be appropriate.

What is the safest endotracheal tube for Nd-YAG laser surgery? A comparative study.
To determine whether a safe endotracheal tube for Nd-YAG surgery could be found, an Nd-YAG laser operating at 50 W was directed at six different endotracheal tubes that had 5 L/min of oxygen flowing through them. A plain Rusch red rubber endotracheal tube, a Bivona Fome-cuff laser endotracheal tube, a stainless steel Mallinckrodt Laser-Flex endotracheal tube, and a Xomed Laser-shield endotracheal tube were all ignited and perforated by the laser within 12 s. ⋯ Red rubber endotracheal tubes wrapped with 3M No. 425 or Venture copper foil tape were unaffected by 1 min of exposure to the laser beam. They are recommended for clinical use.

Hypertonic saline solution-hetastarch for fluid resuscitation in experimental septic shock.
Hypertonic colloid solutions have been found efficacious in the resuscitation from hemorrhagic/traumatic shock. The present study investigated the hemodynamic, gasometric, and metabolic effects of hypertonic colloids in endotoxic shock in the dog. Thirty minutes after administration of 3 mg/kg normal body weight of Escherichia coli endotoxin, dogs were randomly assigned to receive 10 mL/kg hydroxyethylstarch (HES) either in 0.9% NaCl (HES, 10 dogs) or in 7.5% NaCl (HT-HES, 10 dogs) in 30 min. ⋯ Analysis of left ventricular function curves also indicated an improvement in cardiac performance. However, these effects almost completely vanished during the remainder of the study. In the HT-HES group, serum sodium and osmolality levels increased to 167 +/- 4 mEq/L and 344 +/- 4 mOsm/kg H2O, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
