Case ReportsTwo cases in which the effectiveness of "laryngospasm notch" pressure against laryngospasm was confirmed by imaging examinations.
We report two cases in which development of laryngospasm and release of the spasm immediately after applying pressure in the "laryngospasm notch" was confirmed by ultrasonographic and fiberoptic examinations. A bronchoscopy was planned under propofol sedation using a laryngeal mask airway for a 61-year-old man after subtotal esophagotomy. When a bronchoscope was advanced into the trachea, the vocal cords suddenly closed. ⋯ Immediately after this maneuver, the vocal cords opened. We reconfirmed that applying pressure in the "laryngospasm notch" was effective to release laryngospasm. Imaging studies, especially ultrasonographic examination, were useful for making the decision to apply pressure in the "laryngospasm notch."

Randomized Controlled TrialComparative effects of flurbiprofen and fentanyl on natural killer cell cytotoxicity, lymphocyte subsets and cytokine concentrations in post-surgical intensive care unit patients: prospective, randomized study.
The purpose of this study was to compare the effect of the long-term administration of flurbiprofen and fentanyl in the intensive care unit on natural killer cell cytotoxicity (NKCC), lymphocyte subsets and cytokine levels. ⋯ Transient suppressive effects on NKCC were observed in the fentanyl group as compared to the flurbiprofen group. This suggests that when choosing postoperative analgesics, physicians should bear in mind the potential immunosuppressive effects of these agents in patients requiring prolonged sedation in the intensive care unit.

Randomized Controlled TrialEffect of morphine on lower urinary tract discomfort after transurethral resection of prostate under general anesthesia: a randomised clinical study.
Lower urinary tract (LUT) discomfort is a common complaint after transurethral resection of the prostate (TURP), and it may lead to agitation and restlessnes. We have evaluated the efficacy of morphine for preventing TURP-related LUT discomfort symptoms. ⋯ Based on these results, we conclude that morphine effectively reduces LUT discomfort after TURP at a cost of postoperative nausea and vomiting.

Randomized Controlled TrialMild hypercapnia with hyperventilation attenuates recovery from anesthesia in elderly patients.
Mild hypercapnia with hyperventilation has been reported to significantly decrease recovery time from inhaled anesthesia in young and middle-aged patients. However, its efficacy has not yet been clarified in elderly patients, although delayed emergence can deteriorate their quality of recovery. ⋯ Recovery time was significantly decreased by the ANEclear in the elderly group. This reduction was comparable to the time for middle-aged patients.

Effects of battery type and age on performance of rechargeable laryngoscopes.
Optimal visualization of the glottis can be crucial to successful laryngoscopy. Limited information has been published on the light intensity delivered from laryngoscopes powered by rechargeable batteries. In this study the laryngoscope light intensity delivered from 10 nickel metal hydride (NiMH), 7 nickel cadmium (NiCAD), and 2 lithium (LI) batteries with 3-5 or more years of clinical usage were tested in comparison to 5 new NiMH batteries. ⋯ There were significant differences in the time to minimum light intensity among all groups (p = 0.00-0.04). All new and used batteries exceeded the minimum ISO standard of light intensity for more than 10 min. These data demonstrate that rechargeable laryngoscope batteries can safely be used for several years before requiring replacement.
