[Exchange amnioinfusion in conceptus with laparoschisis (first experience)].
OBJECTIVE
During amnioinfusion exchange (AE) a certain amount of amniotic fluid is repeatedly extracted and the same amount of physiological solution is consequently instilled into the amniotic fetal cavity. The aim of this procedure is to dilute the amniotic fluid that surrounds the eviscerated organs of fetuses with laparoschisis so as to avoid the genesis of fibrous coating on these organs.


METHODS
Prospective study.


METHODS
Gynekologicko-pôrodnícka klinika SZU, FNsP akad. L. Dérera, Bratislava, Slovakia.


METHODS
We have executed AE in five fetuses with laparoschisis since June 2002. Two patients underwent the treatment 2 times during the 32nd and 36th weeks of gestation. Two other patients were treated once during the 32nd week and one patient once during the 36th week. Under ultrasound control we used a spinal needle to extract 120-180 ml of dense, cloudy amniotic fluid. Consequently, we instilled the same amount of physiological solution warmed up to the temperature of 37 degrees C into the amniotic cavity through antibacterial filter. The fetuses were monitored cardiotocographically and with the help of ultrasound flowmetry in umbilical vessels, before and after the treatment.


RESULTS
The AE were successful and without complications in all five cases. All patients delivered via elective caesarean section during the 36th - 37th gestation week. One patient delivered 24 hours after second AE due to the danger of intrauterine fetal hypoxia that was verified cardiotocographically. The other patients delivered 1-4 weeks after AE.


CONCLUSIONS
The significance of AE lies primarily in the reduction of the occurrence of fibrous coating on eviscerated organs. It enables postnatal primary surgical closure of the defect in the front abdominal wall, an earlier onset of intestine peristalsis, transition from parenteral to peroral nutrition and shorter hospitalization.
