Neurobehavioral responses and drug concentrations in newborns after maternal epidural anesthesia with bupivacaine.

The neurobehavioral status of 20 newborn infants was evaluated after two to four hours of life following maternal epidural anesthesia with bupivacaine for labor and vaginal delivery. All infants were normal products of uncomplicated full-term gestations. The 20 infants, whose mothers had received continuous lumbar epidural anesthesia with bupivacaine, demonstrated no measurable difference from control infants and did not have the decrease in muscle tone and strength observed in infants whose mothers had received continuous lumbar epidural anesthesia with lidocaine or mepivacaine in a previous study.

A new method of fetal heart rate monitoring.

A new method of continuous fetal heart rate monitoring, employing for cardiotachometry the fetal electrocardiogram obtained from electrodes placed on the maternal abdomen, was evaluated over a period of 26 months at the Lying-in Division of the Boston Hospital for Women. A total of 2460 hours of intrapartum monitoring were analyzed. This "noninvasive" method of fetal ECG-based monitoring was shown to be as accurate as the direct scalp electrode method and more reliable than indirect ultrasound. Useful fetal monitoring, from very early labor up to the time of delivery, was possible in 91% of 507 patients, using maternal skin electrodes alone. Beat-to-beat variability determinations, possibly of significance in evaluating fetoplacental function in the antepartum period, were precise and without the artifactuality of ultrasonic or phonocardiographic methods.

Teaching law students in the medical schools.

Traditional efforts in the law schools to improve interprofessional communication between the medical and legal professions have been confined to abstract case studies and other academic materials, sometimes augmented with visits and demonstrations by physicians in the classroom. This paper describes one approach to broaden the prespective of law students during their training by permitting them to experience directly the atmosphere of the teaching hospital and the sociology of surgery practice in that environment. The experiment has proved beneficial to the young members of both professions.

The relative merits of the heparin-bonded shunt vs. femerofemoral bypass for aortic arch injury.

Six patients with traumatic aortic arch injuries have been repaired with distal aortic perfusion maintained with femerofemoral bypass (three patients) and the heparin-bonded ascending aorta-to-femoral artery shunt (three patients). The two groups are compared regarding pre- and postoperative changes in blood urea nitrogen, creatinine and platelet counts, as well as required blood replacement, days in the hospital, and rapidity of setting up the technique of distal aortic perfusion. No significant difference in the two techniques was demonstrated regarding the above parameters. Both the heparin-bounded shunt and femoral vein-to-femoral artery bypass with the pump oxygenator provide acceptable spinal cord and renal protection. The two techniques should be equally rapid and safe for the larger institution employing cardiopulmonary bypass procedures on a routine basis. The heparin-bounded shunt, however, may provide a more rapid and reliable means of lower aortic perfusion for the smaller institution with less available means of cardiopulmonary bypass support.
