Recombinant factor VIIa in management of spontaneous subcapsular liver hematoma associated with pregnancy.
BACKGROUND: Spontaneous subcapsular liver hemorrhage is a rare but life-threatening complication of pregnancy. Optimal management of an expanding hematoma or ruptured capsule has not been established. CASES: We report 3 patients with preeclampsia and hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome with spontaneous subcapsular liver hematomas. The first 2 patients with ruptured liver hematomas experienced life-threatening hemorrhage. The third patient experienced uncontrollable vaginal bleeding, liver hemorrhage, and was in imminent danger of capsule rupture. Despite aggressive surgical intervention and traditional blood component therapy, adequate hemostasis could not be achieved in any of these patients. Recombinant factor VIIa was used to achieve hemostasis in all three patients. CONCLUSION: Recombinant factor VIIa is an effective adjunct in the treatment of preeclamptic patients with expanding or ruptured subcapsular liver hematoma.

Thrombophilia and pregnancy complications.
The implications of currently available data on the association of gestational vascular complications with thrombophilia are presented in this consensus report. Screening is recommended for women with the following previous complications: fetal loss including three or more first trimester loss, two or more second trimester loss, or any stillbirth; early, severe or recurrent preeclampsia and severe intrauterine growth restriction. Maternal antithrombotic therapy is currently evaluated in women with thrombophilia and previous complications.

The use of rFVIIa in non-haemophilia bleeding conditions in paediatrics. A systematic review.
From its original envisioned use in patients with hemophilia and inhibitors, recombinant factor VIIa has been increasingly used in a variety of non-hemophilia bleeding/hemorrhagic situations with great efficacy. Most of the reported work has been in adult patients. This paper sets out to review its use in the pediatric non-hemophilia patients and the varied conditions it has been tried and used. Most of the published literature has shown that this agent is efficacious, safe and can be used as an adjunctive measure in the achievement of hemostasis. However, most of the published work is mainly anecdotal, case reports or small series. Randomized trials in children are eagerly awaited.

Novel applications of recombinant factor VIIa for the management of pediatric coagulopathic diseases.
Recombinant factor VIIa (rFVIIa) was envisioned for the treatment of bleeding in hemophilia patients with inhibitors. In response to tissue factor expressed upon vessel wall injury, rFVIIa amplifies the thrombin burst primarily on membrane surfaces, including activated platelets. Because it is functional at a key point in the clotting cascade, rFVIIa shows promise as a therapeutic option for various bleeding situations. The prothrombin time (PT) is often used as a surrogate to monitor rFVIIa therapy. Using laboratory and clinical measures of outcome, the use of rVIIa as a therapeutic option in treating several different pediatric coagulopathic conditions is described.

Pain and distress from bone marrow aspirations and lumbar punctures.
OBJECTIVE: To compare the efficacy of 3 different pharmacologic regimens to relieve pain and distress in children with cancer undergoing bone marrow aspirations (BMAs) and lumbar punctures (LPs). DESIGN: Retrospective cohort study with crossovers for some patients. PATIENTS AND METHODS: The pain and distress ratings of patients undergoing BMAs (n = 73) and LPs (n = 105) were examined in a comparison of 3 different interventions: (1) a topical eutectic mixture of lidocaine and prilocaine (EMLA cream), (2) oral midazolam and EMLA cream, or (3) propofol/fentanyl general anesthesia. The choice of the intervention depended on patient/parent request. A validated faces pain scale was completed by the child or parent following each BMA or LP. The faces pain scale includes ratings of the severity of pain (from 0 = none to 5 = severe) and ratings of how frightened (from 0 = not scared to 5 = scared) the child was prior to each procedure. Comparisons of the pain and distress ratings were made among all patients for their first procedure and also within individual patients who had received >1 of the 3 interventions. Independent comparisons between the first treatments received by each patient were analyzed using Kruskal-Wallis tests. Comparisons of different crossover treatments received by individual patients were analyzed using Wilcoxon tests. RESULTS: For all first procedures, mean +/- SD pain and distress ratings during LPs were significantly lower when propofol/fentanyl was used (n = 43; 0.4 +/- 1.0 and 1.4 +/- 1.7) versus either EMLA (n = 29; 2.4 +/- 1.7 and 2.9 +/- 1.9) or midazolam/EMLA (n = 33; 2.4 +/- 1.8 and 2.7 +/- 1.8), respectively. Pain and distress ratings during BMAs were also significantly lower with propofol/fentanyl (n = 29; 0.5 +/- 1.0 and 1.2 +/- 1.7) versus EMLA (n = 21; 3.5 +/- 1.6 and 3.3 +/- 1.8) or midazolam/EMLA (n = 23; 3.3 +/- 1.5 and 3.0 +/- 1.9), respectively. When data were analyzed within each patient, these differences were also present. CONCLUSIONS: Children receiving propofol/fentanyl general anesthesia experienced significantly less procedure-related pain and distress than did those receiving either EMLA or oral midazolam/EMLA.
