Determination of race and sex of the human skull by discriminant function analysis of linear and angular dimensions.

The race and sex of the human skull can be determined by craniometry. In this paper we suggest that a large number of craniometric measurements does not necessarily give the best possible discrimination for race and test the performance of subsets of variables drawn from various skull regions, or extracted mathematically on the basis of their discriminatory power. We also suggest that the best discriminators for race are not necessarily the best for sex, and that skulls of unknown provenance are best tested first for race and then for sex, using different variables for each purpose.

Spinal anesthesia reduces oxygen consumption in diabetic patients prior to peripheral vascular surgery.

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the effect of spinal anesthesia in VO2 in a uniform high-risk patient population and also the relationship between dermatomal level of block and VO2, neither of which has been investigated previously. METHODS: The effect of spinal anesthesia on VO2 was studied in 17 diabetic patients undergoing lower limb peripheral vascular surgery. Measurements were made before and 15 minutes after administration of a tetracaine spinal anesthetic. Values for VO2 and oxygen delivery (DO2) were derived from cardiac output as measured by thermodilution, hemoglobin concentration, and arterial and mixed venous blood gas analysis. The dermatomal level of the sensory block was determined by use of a hand-held nerve stimulator. RESULTS: Mean VO2 decreased by 27.7% (P = .001) (95% confidence limits, decrease of 22.4-90.4%). Mean DO2 and arterial blood gases were unchanged, and the mean postspinal oxygen extraction ratio (VO2/DO2) decreased by 20.5% (P = .002) (95% confidence limits, decrease of 9.1-32.3%). There was a relationship between changes in VO2 and sensory block height (P = .029). CONCLUSIONS: Spinal anesthesia in diabetic patients is associated with a reduction in VO2, the extent of which appears to be, at least in part, a function of the level of spinal sensory block.
