To compare the effects of propofol and thiopentone on tracheal intubation-induced bronchoconstriction, 37 patients were allocated randomly to anaesthesia with either thiopentone 4 mg kg-1 followed by a 15-mg kg-1 h-1 continuous infusion or propofol 3 mg kg-1 followed by a 9-mg kg-1 h-1 continuous infusion. Intubation was facilitated by vecuronium 0.1-0.2 mg(More)
BACKGROUND Anesthesia for surgical reconstruction of scoliosis presents a great challenge for anesthesiologists. One of the main concerns is massive bleeding. Hypotensive anesthesia has been advocated for the purpose of diminishing operative blood loss. On the other hand, some authors reported that the blood loss mostly depends on surgical technique, rather(More)
BACKGROUND Although the mammalian central nervous system contains numerous matrix metalloproteinases (MMPs), the significance of each MMP relative to nociception remains obscure. Working from the hypothesis that MMPs may be involved in activity-dependent reorganization during neuronal modulation, we explored the role of each MMP following neuropathological(More)
Xiaozendao (meaning "small-needle-knife," in Chinese) is a form of alternative medical instrument shaped like an acupuncture needle with a flat edge on the needle tip. It is widely used for the treatment of many different disorders in Asian countries, especially in the People's Republic of China. Its use has gained increasing popularity. To our knowledge,(More)
Of 77 patients who received cardiopulmonary resuscitation (CPR) for an inhospital cardiac arrest from Jan. 1987 to Mar. 1988. 48(68%) survived the initial resuscitation, but only 11(16%) survived to leave hospital. A follow-up survey to Oct. 1988, of these 11 patients showed that one died within 11 months of discharge, but that others were all alive and(More)
Recent reports showed that aminophylline antagonizes the sedation caused by diazepam and narcotic agents. This study examined the antagonism of diazepam and meperidine in extracorporeal shock wave lithotripsy (ESWL) anesthesia by low dose aminophylline. Eighty patients, aged 20-60 year-old, ASA I-II were randomly selected. No premedication was given.(More)
Toxicity of local anesthetics is a serious concern by anesthesiologists while performing regional anesthesia. The toxicity includes convulsion, respiratory difficulty, or sometimes cardiac arrest. Total dose of local anesthetic usually cannot predict the occurrence of toxic effects because these effects are directly correlated to the plasma concentration.(More)
