Because of a hydrocephalic fetus, the 27 year old mother opted for abortion. This was done in the 21st week of pregnancy by ordinary intracervical application of 0.25 mg prostaglandin e2 gel. 30 minutes later the patient began to complain of nausea and dyspnea. Laboratory analysis revealed leukocytosis of 20800/ml and thrombocytopenia of 22000/ml, down from 150,000 ml before the procedure. There were no clinical indications of bleeding. The leukocytosis lasted 2 days and thrombocytopenia roughly 6 days. Treatment included administration of acetylsalicylic acid 3 x 0.5 g and dipyrimadol tablets 3 x 25 mg/day. After thrombocyte count was normalized, abortion was induced by means of spasmolysis and oxytocin i.v. In this case partial resorption of the prostaglandin indicates a systemic effect. Since the half life of E and F group prostaglandins is usually 1-3 minutes, and it is almost completely eliminated after passing through the liver and lungs, a direct prostaglandin effect leading to thrombocyte aggregation lasting several days is unlikely. Absence of thrombocyte antibodies point to a drug induced immune process in which the prostaglandin molecule could appear as a hapten. Ultimately the thrombocyte aggregation described here and normochromic anemia are of unclear origin. Changes in the patients' coagulation system are probably of no functional relevance. The initial leukocytosis must be considered a nonspecific immediate reaction.

A parturient with idiopathic thrombocytopenia received labor analgesia with bilateral paravertebral blocks, because epidural analgesia was contraindicated due to her low platelet count (69,000.microliter-1) even after intravenous administration of freeze-dried sulfonated human normal globulin (400 mg.kg-1.day-1) and transfusion of platelet (20 units.day-1). In spite of predonisolone (1 mg.kg-1.day-1) p.o., her platelet counts could not increase at early gestation period. Prior to the induction of the labor, two catheters were inserted into T 11 bilateral paravertebral spaces, then 0.2% ropivacaine 10 ml was administered in each side, followed by the infusion at 5 ml.hr-1 each for the management of first stage of labor pain. Labor was induced with oxytocin infusion at 2.5-5.0 mU.min-1. As she requested additional analgesia in the second stage of labor, fentanyl 50 micrograms was administered twice intravenously. The labor course was uneventful with adequate analgesia, and the neonate (2,826 g) was vigorous with Apgar scores 9/10. Complications associated with this block such as hypotension, vascular or pleural punctures and pneumothorax were not seen. Bilateral paravertebral blocks may provide adequate analgesia as an alternative method for labor analgesia in a parturient with thrombocytopenia when conventional epidural analgesia is contraindicated.
