HELLP syndrome in the parturient (hemolysis, elevated liver enzymes, and low platelet count) is associated with poor maternal and fetal outcomes. Maternal mortality has been estimated to be as high as 24%. Patients with HELLP syndrome are also at greater risk of pulmonary edema, adult respiratory distress syndrome, abruptio placentae, disseminated intravascular coagulation, ruptured liver hematomas, and acute renal failure. ⋯ Obstetric anesthesia personnel should perform a thorough preanesthetic evaluation and be familiar with the pathophysiologic changes of this syndrome. Determining the anesthetic of choice depends on the patient's condition, fetal well-being, and the urgency of the situation. In the presence of severe coagulopathy, regional anesthesia is contraindicated.

Inhaled nitric oxide (NO) is a selective pulmonary vasodilator in adult and pediatric patients. Inhaled NO diffuses into the pulmonary vascular smooth muscle where it results in vasodilation via stimulation of guanylyl cyclase. Systemic hemodynamics are not altered because inhaled NO is rapidly inactivated by hemoglobin. ⋯ The potential toxicity of inhaled NO, particularly on immature and developing lungs, must be considered. While inhaled NO exerts acute beneficial effects, it is unclear if there are long-term benefits. Multicenter trials are currently underway to determine if inhaled NO decreases mortality from PPHN or decreases morbidity associated with ARDS.

This information was originally presented during the AANA Annual Meeting in August 1996. Accreditors and educators are urged to plan for the future and maintain quality education by anticipating changes in the work and educational environments. Successful adaptation to change will be critical to the future of education and accreditation. A number of factors serving as catalysts to change are described.

The June 1996 article in Anesthesia and Analgesia by Abenstein and Warner entitled "Anesthesia Providers, Patient Outcomes, and Costs" presents important information about anesthesia services, but it contains a number of errors and questionable interpretations that could lead to inappropriate programs and policies. Among the most important points of fact we clarify in our paper are: 1. Three organizations that accredit, certify, and govern nurse anesthetists are organized in similar fashion to three comparable bodies governing anesthesiologists. ⋯ The use of a hypothetical example related to Medicare reimbursement in New York to justify the implication that CRNA-delivered services are more costly than anesthesiologist-delivered services is misleading and not borne out in the literature. We hope that planners and policy makers will read the article by Abenstein and Warner with extreme caution. Taking some of their statements and conclusions seriously could lead to policies and programs that are not focused in science.
