Use of Ultiva ® Associated With Xylocaine ® in the Procedures of Feticide — FOETIVA2  

Termination of Pregnancy Clinical Trial

Official title: Use of Ultiva ® Associated With Xylocaine ® in the Procedures of Feticide: A Phase III Randomized Trial

Status Completed

Clinical Trial Summary

The feticide is a legal and ethical obligation during a termination of pregnancy after 22 weeks' gestation. This method raise concerns about the fetal pain, maternal complications and the fetopathologic analysis. There are few studies on the subject. Investigators want to evaluate a drug in order to facilitate this method technically and emotionally challenging. They want to achieve a quick fetal asystole, a fetal analgesia, a maternal security and a optimal fetopathologic analysis. A drug, remifentanil Ultiva®, seems could meet its properties, it is a powerful morphine. A phase 2 clinical trial has assessed the feasibility, efficacy and safety of Ultiva®. They had not been able to prove bradycardia or lethal effect of Ultiva injected alone but the feasibility and safety were good. Investigators want to set up a randomized clinical trial with 2 arms : Ultiva® and lidocaine versus sufentanil and lidocaine (standard protocol), it is a bicentric study. The primary outcome is the interval between the vascular injection of lidocaine and fetal asystole. The secondary outcomes are the success rate of method, the number of puncture of the umbilical cord, the maternal side effects and the quality of fetopathologic analysis. The previous observational study showed a median interval of 2,3 minutes and a success rate of 55% (lower interval to 2 minutes). From the results they calculate a necessary inclusions to 66 patients. They believe that the bradycardia property of Ultiva® allow a potentiation of the efficacy of lidocaine. If the results are satisfactory, the use of Ultiva® can be generalized to other fetal medicine team.

Clinical Trial Description

The intervention will take place, as in the framework of usual care, obstetric block after achievement of maternal locoregional anesthesia peri-rachianesthesia, skin disinfection and sterile field. The gesture will be performed by an experienced obstetrician under ultrasound guidance. Anesthetist-resuscitator is present in the obstetric block. Peri-rachianesthesia is performed by the initial injection of 2.5mg of hyperbaric bupivacaine associated with 5 gamma of Sufentanil and 0.5ml of physiological saline. Inclusion in one of two arms is defined after randomization in single blind: Arm 1 (Sufentanil + Lidocaïne) or Arm 2 (Ultiva® + Lidocaïne) For patients randomized in the arm 1, we will realize the reference protocol, as in the current practice, by injecting Sufentanil intra-cordally at the posology of 1,5 μg / kg of estimated fetal weight, then Lidocaïne 1% in bolus of 10 ml (10 mg / ml). If 2 minutes after the start of the injection of Lidocaïne, there is no obtaining of fetal asystole, we will inject 100 mg of Lidocaïne 1% into a 10 ml bolus. In case of failure of the procedure, we will inject 10ml of KCL 10% intra-cordial if the cord is still accessible, if not intra-cardiac. For patients randomized to arm 2, we will intracenally inject Ultiva® 30 μg and Lidocaïne 1% into 10 ml bolus (10 mg / ml). If 2 minutes after the start of the injection of Lidocaïne, there is no obtaining of asystole, we will inject 100 mg of Lidocaïne 1% in 10 ml bolus. In case of failure of the procedure, we will inject 10 ml of KCL 10% intra-cordally if the cord is still accessible, if not intra-cardiac. ;
