[Emergency cesarean section in a patient with acute cortical blindness and eclampsia].

A 28-year-old parturient with acute cortical blindness and eclampsia was scheduled for an emergency cesarean section. Computed tomography (CT) of the head revealed low-density areas suggesting cerebral edema in posterior regions. The operation was performed under general anesthesia with sevoflurane. The brain edema was managed by concentrated-glycerin and steroid. The operation was performed uneventfully. Her consciousness returned to normal by the following day and visual recovery was complete within 72 hr postpartum. The patient and the infant showed no complication on their discharge.

[Anesthetic management of caesarean section in a parturient with ankylosing spondylitis complicated with severe cervical myelitis].

A 28-year-old patient with ankylosing spondylitis and cervical myelitis was scheduled for caesarean section. We selected general anesthesia because of her cervical myelitis. Her trachea was intubated using a flexible fiberscope. The patient and the infant had no complications on their discharge.

[Induced hypotension for endoscopic sinus surgery].

The purpose of the present investigation is to examine whether induced hypotension can improve the dryness of the surgical field in endoscopic sinus surgery (ESS). ASA physical status I and II adult patients with chronic sinutitis undergoing ESS were studied. All patients were not premedicated. Anesthesia was induced with propofol and maintained with sevoflurane and fentanyl. The patients were allocated randomly into two groups. In patients of Group C, mean arterial blood pressure (MAP) was maintained around 80 mmHg. In Group H, sodium nitroprusside was infused to maintain controlled hypotension with MAP around 60 mmHg. Blood loss, dryness of the surgical field, volume of fluid infusion and urine output, and surgical as well as anesthetic time were compared. Blood loss and dryness of the surgical field were significantly different between the groups. Volume of infused fluid, urine output, and surgical as well as anesthetic time were not significantly different. Induced hypotension with sodium nitroprusside improved surgical conditions and decreased blood loss in ESS.

Mechanical effects of leg position on vertebral structures examined by magnetic resonance imaging.

BACKGROUND AND OBJECTIVES: Leg manipulation has been postulated to affect spinal curvature and position of the cauda equina within the dural sac. However, no evidence of such mechanical effects has been shown in living subjects. We used magnetic resonance imaging to evaluate the mechanical effects of leg position on these 2 parameters. METHODS: Sagittal and axial magnetic resonance images of the lumbosacral vertebral canal were obtained in 5 healthy, female volunteers with the subject in the supine position with knees straight, knees slightly flexed, and knees fully flexed. RESULTS: In the straight leg position, physiologic lumbar lordosis was evident in all subjects on midline sagittal slices, whereas lumbar lordosis disappeared in the fully flexed leg position. On the axial slices the cauda equina moved ventrally within the dural sac in all subjects in the fully flexed leg position. In 1 of the 5 subjects the cauda equina moved ventrally and also separated completely into right and left parts. CONCLUSIONS: Our findings indicate that 2 potential factors, flattening of the lumbar lordosis and some added tension on the lumbosacral nerve roots, may contribute to postoperative back and leg aching after spinal anesthesia in the lithotomy position.
