Randomized Controlled Trial Clinical TrialHemodynamic stability during induction of anesthesia and tracheal intubation with propofol plus fentanyl, ketamine, and fentanyl-ketamine.
This study was conducted to investigate hemodynamic and cardiac stability during anesthesia induction and intubation, using propofol plus fentanyl, propofol plus ketamine, and propofol plus fentanyl and ketamine. ⋯ A combination of propofol plus fentanyl plus ketamine would provide greater reduction of fluctuations in hemodynamic variables associated with induction of anesthesia and tracheal intubation than combinations of propofol plus fentanyl or propofol plus ketamine.

Tolerance to the analgesic effect of buprenorphine, butorphanol, nalbuphine, and cyclorphan, and cross-tolerance to morphine.
The increased use of opioids in the chronic treatment of pain, especially with oncologic patients, encourages the search for drugs with potent analgesic activity, but with minimal induced tolerance and cross-tolerance to morphine. ⋯ Of the four agonist-antagonists tested, butorphanol seems to be least likely to produce cross-tolerance with morphine.

Effects of ulinastatin (urinary trypsin inhibitor) on ATP, intracellular pH, and intracellular sodium transients during ischemia and reperfusion in the rat kidney in vivo.
To investigate the effects of ulinastatin on renal ischemia-reperfusion injury, we monitored the dynamic changes in ATP, intracellular pH (pHi), and intracellular sodium (Nai) in rats in vivo. ⋯ The transcellular sodium gradient is restored before the ATP level is normalized during postischemic reperfusion. Ulinastatin might protect mitochondrial conformation during ischemia, and facilitate functional recovery of the ionic pump after reperfusion.

The combination of a fiberoptic stylet and a McCoy laryngoscope facilitates tracheal intubation in difficult airway cases.
Fiberoptic stylets are considered useful for difficult airway management. In the present study, we assessed the usefulness of a fiberoptic stylet when the stylet was used with a Macintosh or a McCoy laryngoscope. ⋯ The combination of a new handy fiberoptic stylet and a McCoy laryngoscope facilitated tracheal intubation of patients whose airway had no distance between the epiglottis and the posterior wall of the pharynx in laryngoscopic vocal cord view.
