Advances in anesthesia and pharmacology in the puerperium.

The past year has provided us with some interesting studies concerning pharmacology and anesthesia during the puerperium. I review the prevalence of various anesthetic techniques, as well as the use of different aspiration prophylaxis regimens. I also look at innovations in the administration of epidural and subarachnoid anesthetics, including use of the Sprotte needle to prevent postoperative headache. A small study shows that vitamin administration to premature neonates may prevent periventricular hemorrhage. Furthermore, predelivery injections of glucocortoid may protect against bronchopulmonary dysplasia. I also review painstaking studies that help to better understand thyroid stimulation and regulation during pregnancy. I hope this paper helps the busy obstetrician understand some of the highlights of this year's new literature on obstetric anesthesia and pharmacology.
