HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome: the benefit of corticosteroids.
The purpose of this study was to determine the effect of corticosteroids on platelet counts and liver functions in women with pregnancies complicated by the HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome. ⋯ This study demonstrates that corticosteroids produce a significant improvement in the hematologic abnormalities associated with HELLP syndrome. Two doses of betamethasone given 12 hours apart was the most effective corticosteroid regimen.

Randomized Controlled Trial Clinical TrialPuerperal septic pelvic thrombophlebitis: incidence and response to heparin therapy.
Before the availability of modern imaging studies the diagnosis of septic pelvic thrombophlebitis causing prolonged puerperal fever was difficult to confirm without surgical exploration. With the use of computed tomography infection-related pelvic phlebitis can now be confirmed, and this study was designed to determine its incidence after delivery. We also designed a randomized clinical trial to evaluate the efficacy of heparin added to antimicrobial therapy for treatment of women with septic phlebitis. ⋯ The overall incidence of septic pelvic thrombophlebitis was 1:3000 deliveries. The incidence was about 1:9000 after vaginal delivery and 1:800 after cesarean section. Women given heparin in addition to antimicrobial therapy for septic thrombophlebitis did not have better outcomes than did those for whom antimicrobial therapy alone was continued. These results also do not support the common empiric practice of heparin treatment for women with persistent postpartum infection.

Case ReportsPelvic arterial embolization for control of obstetric hemorrhage: a five-year experience.
Obstetric hemorrhage is a significant cause of maternal morbidity and death. Postpartum hemorrhage that cannot be controlled by local measures has traditionally been managed by bilateral uterine artery or hypogastric artery ligation. These techniques have a high failure rate, often resulting in hysterectomy. In contrast, endovascular embolization techniques have a success rate of >90%. An additional benefit of the latter procedure is that fertility is maintained. We report our experience at Stanford University Medical Center in which this technique was used in 6 cases within the past 5 years. ⋯ Uterine artery embolization is a superior first-line alternative to surgery for control of obstetric hemorrhage. Use of transcatheter occlusion balloons before embolization allows timely control of bleeding and permits complete embolization of the uterine arteries and hemostasis. Given the improved ultrasonography techniques, diagnosis of some potential high-risk conditions for postpartum hemorrhage, such as placenta previa or accreta, can be made prenatally. The patient can then be prepared with prophylactic placement of arterial catheters, and rapid occlusion of these vessels can be achieved if necessary.

Risk factors for abruptio placentae and eclampsia: analysis of 445 consecutively managed women with severe preeclampsia and eclampsia.
Our purpose was to characterize the clinical presentation or laboratory variables predictive of either abruptio placentae or eclampsia in women with severe preeclampsia. ⋯ Quantitative proteinuria and degree of blood pressure elevation were not predictive of either abruptio placentae or eclampsia, as has previously been suggested. The greatest morbidity associated with eclampsia occurred in women with preterm gestations not receiving medical attention.

Early risk assessment of severe preeclampsia: admission battery of symptoms and laboratory tests to predict likelihood of subsequent significant maternal morbidity.
This study was undertaken to investigate the utility of an admission battery of findings and laboratory data in the discrimination of patients with severe preeclampsia with or without HELLP (hemolysis, elevated liver enzyme levels, and low platelet count) syndrome at high risk for development of significant maternal morbidity. ⋯ The presence of nausea and vomiting, epigastric pain, or both in association with admission laboratory values that are in excess of the cutoffs for lactate dehydrogenase, aspartate aminotransferase, and uric acid concentrations or for all 6 tests is predictive of high risk of morbidity for the patient with severe preeclampsia. These factors are independent of and additive with the rising maternal risk associated with decreasing platelet count.
