[Contamination of the operating room by anesthetic gases and vapors. II. Gas chromatographic analysis of nitrous oxide].
The contamination by nitrous oxide of an operating room atmosphere was studied in a number of experiments, in the absence of personnel and using a gaschromatographic method. The evacuating device of the anesthesia machine proved to be ineffective to overcome the hazard of leaks in the breathing system, whereas the air conditioning flow rates (12 outside air changes per hour) minimized waste anesthetic gas concentrations.

The effects of bupivacaine and chloroprocaine as local anesthetics for epidural anesthesia of fetal heart rate monitoring parameters.
The effects of saline-induced pressure-volume changes in the epidural space, and bupivacaine and chloroprocaine as local anesthetics for epidural anesthesia, on various fetal heart rate monitor parameters were investigated in 34 low-risk women. Epidural space pressure-volume changes, bupivacaine, and chloroprocaine had no effect on the incidence of pathologic periodic fetal heart rate changes, the level of the baseline fetal heart rate, or the level of uterine activity units. Epidural space pressure-volume changes and chloroprocaine did not affect fetal heart rate variability. The use of bupivacaine was associated with a significant increase in fetal heart rate variability
