Intrauterine pressure and fluid absorption during continuous flow hysteroscopy.
Our objectives were to document the causes of fluid absorption during continuous flow hysteroscopy and to determine under which operative conditions fluid overload may occur. ⋯ Intravasation of fluid may occur through open uterine venous channels with extensive resections and under low pressures in the presence of unrecognized perforations.

Case ReportsSuccessful pregnancy outcomes after amniotic fluid embolism.
Two patients who survived cardiorespiratory arrest occurring in association with amniotic fluid embolism syndrome were seen during the subsequent pregnancy. Both had uneventful pregnancies and delivered at term without complications. These are the only case reports of pregnancy after amniotic fluid embolism, and they support a model of amniotic fluid embolism involving chemically abnormal amniotic fluid rather than an unusual sensitivity to normal amniotic fluid.

Prenatal diagnosis of human parvovirus B19 in nonimmune hydrops fetalis by polymerase chain reaction.
Nonimmune hydrops fetalis is a potentially lethal condition reflecting the clinical manifestation of several pathologic processes. Recently maternal infection by human parvovirus B19 has been reported to result in nonimmune fetal hydrops. We sought to develop a rapid and sensitive test to detect the presence of this agent in utero. ⋯ The method is powerful in that it is rapid, sensitive, and simple. This assay may have general applicability in evaluation of nonimmune hydrops and in documentation of the natural history of fetal human parvovirus infections.

Our objective was to determine the incidence of blood transfusion in patients delivered by cesarean section and to identify factors predictive of the need for transfusion. ⋯ Transfusion with cesarean section is common and is associated with antepartum bleeding and other primarily intrapartum and unpredictable factors.

ReviewEthically justified guidelines for family planning interventions to prevent pregnancy in female patients with chronic mental illness.
This article proposes ethically justified clinical guidelines for family planning interventions to prevent pregnancy in female patients. ⋯ Three sets of guidelines for three groups of patients, representing the continuum of chronically and variably impaired autonomy, are proposed: (1) a set of guidelines for patients who can achieve thresholds of autonomy, (2) a set of guidelines for patients irreversibly near thresholds of autonomy, and (3) a set of guidelines for patients irreversibly below thresholds of autonomy. These guidelines should contribute significantly to the quality of obstetric and gynecologic care for female patients with chronic mental illness.
