Randomized Controlled Trial Clinical TrialSafety and beneficial effect on body core temperature of a prewarmed plasma substitute--hydroxyethyl starch--during anesthesia.
We investigated, first, the safety of use and stability of a plasma substitute-hydroxyethyl starch (HES)-kept in a warming cabinet for a long period, and then the effect on body core temperature of the prewarmed HES in patients during urological surgery. ⋯ The use of HES products kept in a warming cabinet prior to surgery can maintain warm body temperature, easily, safely, and effectively.

Randomized Controlled Trial Clinical TrialEffects of oral atenolol on volatile anesthetic induction with sevoflurane in adults.
To determine whether premedication with a beta-blocker can bring about a more rapid and smooth induction of anesthesia, we investigated the effect of oral premedication with atenolol on volatile anesthetic induction with sevoflurane by monitoring the cardiac output (CO) and bispectral (BIS) index. ⋯ Oral premedication with 25 mg of atenolol provides a more rapid decrease in BIS index and is recommended for use in stable volatile anesthetic induction with sevoflurane.

Clinical Trial Controlled Clinical TrialLaryngotracheal application of lidocaine spray increases the incidence of postoperative sore throat after total intravenous anesthesia.
To determine the effect of laryngotracheal application of different doses of lidocaine spray on postoperative sore throat and hoarseness, we evaluated the incidence and severity of these complications in 168 ASA I-III patients aged 15-92 years in a placebo-controlled study. ⋯ We recommend that applications of lidocaine spray to the laryngotracheal area should be avoided to help eliminate unnecessary postoperative sore throat, thereby leading to improvement in patient satisfaction.

Effects of withdrawal of phasic lung inflation during normocapnia and hypercapnia on the swallowing reflex in humans.
This study was done to test the hypothesis that hypercapnia has a direct, inhibitory effect on swallowing. ⋯ The results of our study strongly suggest that the attenuation of the swallowing reflex during hypercapnia is not due to the direct, inhibitory effect of CO2 on the swallowing center, but, rather, is due to the increased inhibitory influence of a lung-volume-related reflex.

Duration of vecuronium-induced neuromuscular block can be predicted by change of skin temperature over the thenar muscles.
The purpose of this study was to clarify the relationship between skin temperature over the thenar muscles and the duration of action of vecuronium measured acceleromyographically at the thumb in anesthetized patients. ⋯ Our results show that peripheral ST decreases considerably during open abdominal surgery without reduction in core temperature, and the decrease contributes to the potentiation of neuromuscular block in the periphery during propofol, fentanyl, and nitrous oxide anesthesia.
