Epidural anesthesia for cesarean section in diabetic parturients: maternal and neonatal acid-base status and bupivacaine concentration.
Acid-base status and blood levels of bupivacaine were determined in 16 diabetic parturients and their infants after epidural anesthesia for cesarean section. The newborn infants were divided into two groups based on umbilical artery pH at birth. ⋯ In addition, the half-life to bupivacaine was prolonged in acidotic infants. The placental transfer of bupivacaine, as judged by umbilical vein/maternal vein ratios, was significantly greater in acidotic infants.

Performance evaluation: continuous lumbar epidural anesthesia skill test.
The evaluation of skills in anesthesiology residents is usually subjective and lacks demonstrable reliability. Therefore, an objective criterion-referenced skill test for measuring performance of continuous lumbar epidural anesthesia was developed. For such a test to be useful, it is necessary to demonstrate agreement among rater-observers. ⋯ Inter-rater agreement was analyzed by determining coefficient kappa for each item and the entire test. Coefficient kappa for the entire test was 0.82 indicating a high degree of agreement between raters on the performance or nonperformance of various items. Development and utility of skill tests are discussed.
