[Assessment of anxiety, pain and its management in prenatal diagnosis procedures]. / Évaluation de l'anxiété, de la douleur, et de leur prise en charge dans les gestes de diagnostic anténatal.

UNLABELLED: Invasive prenatal diagnosis procedures are numerous and more or less painful and stressful. The purpose of this study was to investigate maternal perception of both anxiety and pain before and after amniocentesis (AC) or transabdominal chorionic villus sampling (CVS), to determine factors associated with pain and anxiety, and to evaluate the pain support. This is a prospective study evaluating the professional practices at CHRU of Lille between March and May 2009 with 132 AC and 22 CVS by aspiration. An original questionnaire has been elaborated in three parts: the first one fulfilled by patients before the procedure, the second one, after the procedure, and the last one by the medical team. Statistical comparisons have used the Chi(2) test, the Fisher exact test, the Student's t test and the U test of Mann Whitney. RESULTS: The anxiety level is high but does not differ between the two groups AC and CVS. CVS are more painful than AC (EVA 5.77 versus 3.07, P<0.0001). No predisposing factor for anxiety has been found. On the other side, procedures are more painful when they are long lasting, considered difficult by the medical team, when needles used are large, the number of needle insertions increases, puncture is performed along a side of the uterus, patients are anxious, and then procedure indication is an hygroma. Patients are satisfied in 98.7% of cases of the support of the medical team. Few drug treatments was prescribed (only 4.5%), however, patients are generally applicant. CONCLUSION: An analgesic, anxiolytic, or a relaxation technique can be proposed to anxious and applicant patients undergoing CVS. Technical conditions of the procedure are more difficult to improve, however, we should use if possible thinner needles, and avoid, wherever technically possible, the punctures on the lateral side of the uterus. Finally, further studies seem necessary for the evaluation of a treatment protocol.

Use of inhaled nitric oxide for emergency Cesarean section in a woman with unexpected primary pulmonary hypertension.

PURPOSE: Use of inhaled nitric oxide (iNO) could be of importance in emergency cases of primary pulmonary hypertension (PPH) in pregnant patients during labour and delivery. iNO acts as a selective pulmonary bed vasodilator avoiding systemic hemodynamic effects due to its ease of administration. Pulmonary bed vasodilation improves right ventricular function directly and left ventricular function indirectly. CLINICAL FEATURES: We report the case of a pregnant patient with unexpected PPH in whom an emergency Cesarean section (CS) had to be performed. PPH was diagnosed on admission as she arrived in active labour at 34 weeks gestational age. An emergency CS was performed under epidural anesthesia for breech presentation . All along labour, delivery and the first 24 hr, iNO was administered via a noninvasive ventilation device. CS was uneventful. A severe pulmonary hypertensive crisis was observed 12 hr after delivery and resolved with an increase of iNO concentration and administration of isoprenalin. The patient and baby returned home on day ten. CONCLUSION: The ease of administration of iNO allowed the optimal control of pulmonary arterial hypertension. No interaction with epidural anesthesia was observed. Use of iNO can improve the management of urgent CS in women with unexpected PPH.

Recombinant tissue type plasminogen activator treatment of thrombosed mitral valve prosthesis during pregnancy.

PURPOSE: Prosthetic heart valve thrombosis occurring during pregnancy is a life-threatening complication. Surgical treatment requires clot removal under cardiopulmonary bypass (CPB) and carries a high mortality. We describe the successful use of thrombolytic therapy for recurrent thrombosed valve prosthesis in a pregnant patient. CLINICAL FEATURES: A 32-yr-old patient whose pregnancy was complicated by two episodes of a thrombosed St Jude mitral prosthesis is reported. The first episode occurred at 20 wk of pregnancy during the change of oral anticoagulant therapy (acenocoumarol 4 mg a day) to sc heparin. As the patient was in cardiogenic shock, the valve thrombus was treated by clot removal under CPB., with a cross clamp time of 32 min, a perfusion pressure above 70 mmHG. There was no fetal cardiac rhythm during CPB which lasted < 45 min. The second episode occurred at the 28th gestational week in a patient in cardiogenic shock and because reoperation was thought to carry too high a risk, the thrombus was successfully treated with 50 mg recombinant tissue plasminogen activators (rtPA) i.v. Following this, the course of pregnancy was uneventful and carried to term and the patient delivered vaginally. Pain relief was achieved with intravenous patient-controlled analgesia with alfentanil (bolus 100 mug; lock out = five minutes). Although rtPA has been used before, this is the first report in which pregnancy was carried to term and standard vaginal delivery performed. CONCLUSION: This case provides evidence for the efficacy and relative safety of rtPA as thrombolytic therapy in the treatment of haemodynamically compromised valve heart thrombosis in pregnancy.

Pregnancy after myocardial infarction and a coronary artery bypass graft.

The authors report a pregnancy in a 34 year old patient who previously experienced a myocardial infarction. The pregnancy ended at 39 weeks in the birth of a healthy girl weighting 3040 g, by cesarean section under epidural anesthesia. A review of the literature revealed 33 similar cases, 16 of which were adequately documented.
