Case Reports
[Anesthesia for the intraoperative electrocorticography of patients with uncontrollable epilepsy].
For the surgical treatment of uncontrollable epilepsy, it is essential to delineate the epileptogenic focus by the use of intraoperative electrocorticography. Most general anesthetic agents, however, suppress the epileptogenic focus. Therefore, such a patient is usually kept awake during the procedure using local anesthesia. ⋯ In 2 patients, electrocorticographical focal seizure status was identified following the intraoperative electrocorticography. After the focus resection, seizure attacks were controlled only by the application of regular medical regimen in these patients. Low nitrous oxide and intermittent fentanyl administration can be recommended as a superior anesthesia technique for intraoperative electrocorticography.

Randomized Controlled Trial Clinical TrialFlumazenil facilitates intraoperative arousal during scoliosis surgery: a randomized, double-blind, placebo-controlled study.
Intraoperative arousal was evaluated in 24 patients (median age 16.5 years), undergoing spondylodesis with Cotrel-Dubousset or Harrington-Luque instrumentation. Flumazenil and placebo groups of 12 patients each were similar with respect to age, body weight, dosage of anaesthetic drugs and surgery times. Premedication consisted of diazepam 0.2-0.3 mg kg-1 orally. ⋯ Postoperatively, motor responses were assessed after 12.0 min (5-42 min) in the flumazenil group, and after 15.2 min (4-40 min) in the placebo group (NS). Recovery from anaesthesia took 27.5 min (7-415 min) in the flumazenil group, and 25.0 min (8-160 min) in the placebo group (NS). One patient given flumazenil and one patient given placebo remembered moving their feet, but neither of them could recall anything unpleasant.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial[Mechanomyographic and electromyographic studies of endotracheal intubation with 2 different rocuronium dosages].
Rocuronium is a new, intermediate-acting, nondepolarizing relaxant with rapid onset of action leading to both good and very good intubation conditions. It was the aim of our study to investigate the onset of action, the intubation conditions and the course of relaxation using two different dosage regimes. Thirty consenting ASA 1 and 2 patients received either 0.6 mg/kg (2 x ED 95; group 1) or 0.06 mg/kg as priming dose followed by an intubating dose of 0.24 mg/kg rocuronium (group 2) four min later. ⋯ The clinical duration of action was significantly longer in group 1 (28.4 +/- 8.0 min) than in group 2 (14.8 +/- 2.5 min). It can be concluded that rocuronium which has shorter intubation times than atracurium and vecuronium is very useful for endotracheal intubation in both dosage regimes in long and very long lasting operations. Using the "priming principle" the patient has to be carefully controlled during priming time.

Anaesthesia for fetal distress is usually indicated for emergency caesarean section. General anaesthesia, which is the classical technique in these cases, remains the leading cause of anaesthesia-related maternal mortality. Difficult intubation and Mendelson's syndrome are mostly responsible for these fatalities. ⋯ For example, a "prophylactic" epidural instituted soon after the beginning of labor may be lifesaving in a patient with obvious signs of difficult intubation. A clear definition of safe standards of equipment and practices both to prevent Mendelson's syndrome or to cope with a failed intubation through a "failed intubation drill" is of paramount importance. Finally, a comprehensive communication between anesthetic and obstetrical teams is one of the most useful ways to allow a safer approach of the management of obstetric emergencies such as caesarean section for fetal distress.
