We evaluated clinical efficacy of near infrared spectroscopy (NIR) as a monitoring system for cerebral oxygenation during anesthesia for carotid artery endarterectomy. NIR proved to be affected significantly by clamping of the external carotid artery. The present study suggests that this monitoring system may be useful for evaluation of cerebral blood flow following declamping of the internal carotid artery, although it has some limitations during clamping of the artery.

Case Reports
[Rhabdomyolysis induced by succinylcholine chloride and sevoflurane in an elderly man].
An 81-year-old man was scheduled for cervical lymph node biopsy. His laboratory data were within normal ranges. After induction of anesthesia with thiopental 175 mg and succinylcholine chloride (SCC) 40 mg, moderate masseter spasm was observed. ⋯ The skinned fiber examination, performed one month later, showed his calcium-induced-calcium-release (CICR) to be within normal ranges. We diagnosed him as rhabdomyolysis induced by coadministration of SCC and sevoflurane, especially SCC. We concluded that even in an elderly man, SCC should be administered cautiously.

Eighteen neonates and infants scheduled for cardiac surgery, ranging from 1 to 42 months in ages and from 1.9 to 14.6 kg in weight, were placed in supine position under general anesthesia. The neck was moderately extended with the head turned to the left. The pathways of the right carotid artery and the internal jugular vein (IJV) were located with a Doppler probe (2.0 mm in diameter, HAYASHI Electric, TOKYO) using 10 MHz ultrasound wave. ⋯ In the remaining 2 patients the left IJV was catherized using the same method. No complications related to the catheterization were observed. Our catheterization method is thought to be highly reliable and safe in small pediatric patients.
