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.

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)
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)
A case of intrahepatic metastatic pheochromocytoma with lymph nodes involvement undergoing resection of tumor was reported; intravenous labetalol in high dose regimen (2 mg/kg administered before skin incision) was used for blood pressure control during the operation. Marked sinus bradycardia was noted after receiving total dose of intravenous labetalol and(More)
Seven patients scheduled for resection of pheochromocytoma with loose preoperative control of their blood pressure were selected in our study. All the cases are impressed of pheochromocytoma that predominantly excrete norepinephrine. Anesthesia was induced with fentanyl, 2.5% sodium thiopental, valium and atracurium. Labetalol was used as antihypertensive(More)
