Randomized Controlled Trial Comparative Study Clinical TrialComparison of neuromuscular action of rocuronium, a new steroidal non-depolarizing agent, with vecuronium.
Rocuronium is a new nondepolarizing muscle relaxant. It features a rapid onset and lack of histamine release: It has an intermediate onset of action as vecuronium. The purpose of this study was to compare the neuromuscular action and condition of intubation after a bolus dose of rocuronium or vecuronium (2 x ED90). We also compared the duration of relaxation after intubation and maintenance doses of each drug. ⋯ We conclude that rocuronium provides a more rapid onset of action than that of vecuronium. Rocuronium is an intermediate-acting muscle relaxant as vecuronium with good to excellent intubation condition. It may be an useful alternative to vecuronium for rapid tracheal intubation.

Evoked facial nerve EMG and brainstem auditory evoked potential monitoring in cerebellopontine angle tumor resection.
The preservation of normal nerve function or identification of nerve route is critical in some surgeries of cerebellopontine angle tumors. Over the last 5 years, intraoperative facial nerve electromyogram (EMG) and brainstem auditory evoked potential (BAEP) were applied for evaluation of facial nerve integrity and brainstem function in patients while undergoing resection of cerebellopontine angle (CPA) tumor. This report represents the retrospective analysis of our results. ⋯ The low incidence of false negative test suggests that facial nerve EMG is valuable in detection of facial nerve function in CPA tumor resection. Intraoperative BAEP abnormality is possibly useful in identifying postoperative brainstem dysfunction.

Case ReportsAnesthetic management in a parturient with progressive systemic sclerosis during cesarean section--a case report.
This case report concerns a successful Cesarean section (C/S) delivery in an expectant woman affected with progressive systemic sclerosis (PSS) with clinical manifestations of severe pulmonary hypertension (PH), cor pulmonale, severely restrictive ventilatory impairment, pregnancy-induced hypertension (PIH), and esophageal dysfunction under general anesthesia (GA). This is an extremely rare condition in obstetrics and the victim is usually in a great peril of conception, delivery, surgery and anesthesia because of poor pulmonary and cardiac reserves. We herewith reported our experience in two GAs given uniquely to the same patient who was affected with the disorder and discuss the problem.

Randomized Controlled Trial Comparative Study Clinical TrialIntermittent bolus versus patient-controlled epidural morphine for postoperative analgesia.
Patient-controlled epidural analgesia (PCEA) is a technique that combines the flexibility and convenience of PCA with the intrinsic analgesic efficacy of epidurally administered opioids. The aim of this study is to compare the analgesic and side effects of intermittent bolus injections of epidural morphine with PCEA using morphine during the first 24 h after elective low abdominal surgery. ⋯ PCEA with morphine decreases morphine consumption and with less adverse effects than intermittent bolus of epidural morphine. PCEA with morphine is an acceptable alternative to epidural morphine after low abdominal surgery.

Case ReportsTruncal rigidity as a result of epidural sufentanil--a case report.
It is well known that intravenous opioids may cause truncal rigidity. To the best of our knowledge truncal rigidity induced by epidural opioid has never been reported. Recently, we came across an accident of truncal rigidity following epidural sufentanil. ⋯ She stayed in the recovery room for 24 h and returned to ward in satisfactory condition. The incidence disclosed that epidural sufentanil even with a dose as small as 50 micrograms could cause truncal rigidity. Thus when epidural sufentanil is applied for post-operative pain control constant vigilance is necessary in order to avoid accident.
