[Anesthetic management for a child with bilateral pheochromocytoma].

We report anesthetic management for a 13-year-old boy undergoing surgical removal of the bilateral adrenal pheochromocytoma. His blood pressure was well-controlled at the time of the operation with an alpha-adrenergic receptor-blocking agent and a calcium channel blocker. His laboratory test, however, showed anemia and prolonged clotting time.

[Ilioinguinal nerve block during general anesthesia for inguinal herniorrhaphy in adult anticoagulated patients].

Two adult anticoagulated patients after valve replacement were scheduled for inguinal herniorrhaphy. For inguinal herniorrhaphy in adults, spinal anesthesia is a common anesthetic method. In order to avoid spinal hematoma due to spinal anesthesia, however, we employed general anesthesia combined with ilioinguinal nerve block.

[Ilioinguinal/iliohypogastric nerve block for pediatric inguinal herniorrhaphy; evaluation of the dose of ropivacaine].

Background: The aim of this study was to investigate the appropriate dose of ropivacaine in efficacy and safety when administered for ilioinguinal/iliohypogastric nerve block in children undergoing inguinal herniorrhaphy.

Methods: Forty six children (aged 1-8 yr, classified ASA I-II) undergoing ambulatory surgery for inguinal herniotomy were randomly assigned to one of the three groups, according to the dosage of ropivacaine: group I (n = 15), group II (n = 16) and III (n = 15) received 1.875, 0.

Intraoperative monitoring of myogenic motor-evoked potentials from the external anal sphincter muscle to transcranial electrical stimulation.

Study Design: Motor-evoked potentials from the external anal sphincter were analyzed using transcranial electrical stimulation during spinal surgery in patients under general anesthesia.

Objective: To investigate whether motor-evoked potentials from the external anal sphincter could be elicited by transcranial electrical stimulation under general anesthesia.

Summary Of Background Data: Lumbosacral surgery often places nerve rootlets at risk for injury during operative dissection.

[Incidence and duration of hoarseness following endotracheal intubation].

The incidence and duration of hoarseness following tracheal intubation with general anesthesia were studied retrospectively from November 1998 to October 2000 in postanesthetic clinic of Nara Medical University. Total number of patients was 3977 and 37.1% of them complained of hoarseness.

[Paradoxical embolism during MIDCAB surgery].

A 36-year-old woman underwent MIDCAB surgery. During the exposure of LAD, the right ventricular wall was injured. The bleeding was controlled by compression.

[Effects of amrinone in patients undergoing off-pump coronary artery bypass grafting].

We evaluated the effect of amrinone in 41 patients undergoing off-pump coronary artery bypass grafting(CABG) retrospectively. Amrinone was intravenously administered at the rate of 5 mcg.kg-1.
