Clinical TrialSystemic vascular resistance index determined by thoracic electrical bioimpedance predicts the risk for maternal hypotension during regional anesthesia for cesarean delivery.
Our purpose was to evaluate the predictive value of the baseline systemic vascular resistance index for the development of maternal hypotension during regional anesthesia for cesarean delivery. ⋯ Baseline systemic vascular resistance index obtained by noninvasive cardiac output monitoring with thoracic electrical bioimpedance and systolic blood pressure are useful to predict the risk for maternal hypotension with regional anesthesia. Patients with increased baseline systemic vascular resistance index or systolic blood pressure are at increased risk for hypotension.

Cardiac oxygenation by extracorporeal membrane oxygenation in exteriorized fetal lambs.
The purpose of this study was to determine the degree of cardiac oxygenation produced by different routes of extracorporeal membrane oxygenation in fetal lambs submerged in warm saline solution. ⋯ More effective cardiac oxygenation is provided by right atrium to umbilical vein extracorporeal membrane oxygenation than by right atrium to carotid artery extracorporeal membrane oxygenation.

Ovarian cysts in premenopausal and postmenopausal tamoxifen-treated women with breast cancer.
Our purpose was to investigate the frequency of ovarian cysts in tamoxifen-treated breast cancer patients. ⋯ Ovarian cysts are a common side effect of tamoxifen treatment. The ovarian cysts can develop in tamoxifen-treated premenopausal as well as postmenopausal women with breast cancer. Most of the tamoxifen-associated cysts disappear after tamoxifen treatment is abandoned.

Our purpose was to evaluate the relative weight of the different variables that may influence the chances of vaginal birth after one cesarean delivery, with the aim of developing a predictive score for success of such a trial. ⋯ A trial of labor after one cesarean section should be encouraged in most women who are willing to attempt it, provided no obstetric contraindication exists. A scoring system that may help to identify women with a greater chance for vaginal delivery is proposed.

ReviewEthically justified clinically comprehensive guidelines for the management of the depressed pregnant patient.
This article proposes ethically justified clinical guidelines for managing depressed patients during pregnancy. ⋯ When the fetus is previable, recommendations concerning the disposition and prenatal diagnosis of the pregnancy should be nondirective, whereas strong treatment recommendations are justifiable if the pregnant woman has decided to continue her pregnancy and is severely depressed. After viability, directive counseling for fetal benefit is ethically justified. The guidelines focus on preventive ethics strategies to enhance the decision-making capacity of the depressed pregnant patient.
