Randomized Controlled Trial Comparative Study Clinical TrialLidocaine: the optimal timing of intravenous administration in attenuation of increase of intraocular pressure during tracheal intubation.
This study was designed to examine the optimal timing of intravenous lidocaine in attenuation of increase of intraocular pressure in response to laryngoscopy and tracheal intubation during induction of anesthesia. ⋯ In healthy patients aged between 20 and 35 the most optimal time of administration of intravenous lidocaine to attenuate the increase of intraocular pressure seemed to be the space between 1 to 3 min before laryngoscopy and tracheal intubation.

Randomized Controlled Trial Clinical TrialEpidural ropivacaine for postoperative analgesia in Taiwanese patients.
Ropivacaine is the latest long-acting amide local anesthetic. As it is less cardiovasculotoxic and neurotoxic than bupivacaine it is an attractive anesthetic agent used in clinical anesthesia and postoperative analgesia. This study was undertaken to seek for a suitable dosage of ropivacaine in postoperative analgesia for Taiwanese patients whose average physicality is not entirely compatible with the pharmacopeially recommended dosage for western people. ⋯ From the results of this study, we are of the opinion that 0.125% ropivacaine could provide a postoperative analgesia in Taiwanese patients to their satisfaction with less adverse effects.

Randomized Controlled Trial Comparative Study Clinical TrialA randomized, prospective comparison of end-tidal CO2 pressure during laparoscopic cholecystectomy in low and high flow anesthetic system.
Low flow anaesthesia has been used in anesthetic practice to prevent operation room pollution and also for econormical reasons. Since the safety of low flow technique has not been clearly determined in previous researches this study was performed to compare the end-tidal CO2 pressure during laparoscopic cholecystectomy in low flow as opposed to high flow anesthesia. ⋯ The result of this study shows that end-tidal CO2 pressure during laparoscopic cholecystectomy using low flow anesthesia system is comparable to that with high flow system. Therefore it can be concluded that low flow anesthesia can be used with relative safety in anesthetic management of patients during laparoscopic cholecystectoy.

Randomized Controlled Trial Comparative Study Clinical TrialTracheal intubation condition--a comparison between one minute after rocuronium alone, one minute after rocuronium combined with atracurium and one minute after atracurium with rocuronium at one minute priming interval.
Rocuronium, a monoquaternary steroid analogue of vecuronium, is designed to provide a rapid onset of action. Experimentally, it has been shown that two non-depolarizing neuromuscular relaxants administered together can produce either a neuromuscular block of a size expected to be the sum of the individual doses (additive effect) or a larger neuromuscular block (synergistic effect). Experimental observations have suggested that during onset rocuronium acts synergistically with other nondepolarizing agents, but that at a steady state the combined action is additive. ⋯ Statistically, rocuronium alone, mixture of equipotent atracurium and rocuronium, and using rocuronium to prime atracurium all provided similar onset for satisfactory intubation.

Randomized Controlled Trial Clinical TrialOral clonidine reduces myocardial ischemia in patients with coronary artery disease undergoing noncardiac surgery.
To access the clinical effect of clonidine on reduction of myocardial ischemia events in patients with history of coronary artery disease undergoing noncardiac surgeries. ⋯ We conclude that premedication with oral clonidine can significantly reduce the incidence of perioperative myocardial ischemia in patients with CAD undergoing noncardiac surgeries. The incidence of myocardial ischemia in these patients is rather high during perioperative period, which deserves our exceptional caution.
