. [ ] However, there is an increased risk of primary cesarean delivery with increasing maternal BMI. Complications Polyhydramnios Risks and complications of amnioinfusion include amniotic fluid embolism, maternal respiratory distress, increased maternal uterine tone, and transient fetal respiratory distress. An increase in the risk of maternal or fetal infection is not substantiated. Risks of amniocentesis include fetal loss (1-2%). Other complications are placental abruption, preterm labor, fetal-maternal (...) A, Greenspoon JS, Paul RH.

obtained before second-trimester amnioinfusion. This fetus has bilaterally absent kidneys consistent with a diagnosis of Potter syndrome. The cystic structures in the renal fossae are most likely the adrenal glands. Next: Pathophysiology Prior to 16 weeks' gestations, the amount of amniotic fluid is dependent on the transmembrane flow. After that, fetal urine production is the predominant mechanism that determines the amniotic fluid volume. The fetus continuously swallows amniotic fluid, which (...) and therapeutic transabdominal amnioinfusion in oligohydramnios. Obstet Gynecol . Aug/1991. 78(2):270-8. . . Raboei EH.

83. Antenatal Hydronephrosis (Follow-up)
in initial attempts (eg, use of amnioinfusion to enhance fetal visualization, use of fetal paralysis, routine use of antibiotics, and increased focus on proper catheter placement), as well as specific outcome measures needed for appropriate evaluation of the effects of fetal intervention (eg, gross survival, postnatal survival, shunted survival, and nadir creatinine at 1 year). [ ] Laparoscopy has also been described but has been associated with high rates of complications. [ ] Fetal cystoscopic ablation (...) of posterior urethral valves has been described; success rates have varied. [ ] The fetoscope is passed percutaneously through a cannula into the fetal bladder, and ablation of the valves is achieved with laser coagulation. Other less invasive techniques have been developed to help prevent oligohydramnios-induced pulmonary hypoplasia. As previously mentioned, serial transabdominal amnioinfusion is helpful in placement of percutaneous shunts. It may also have a therapeutic role in the reduction of pulmonary

and expect some lung growth and development. Serial amnioinfusions have been helpful in certain cases of oligohydramnios. In the extrauterine intrapartum (EXIT) procedure, the fetal head, neck, and shoulders are delivered through a uterine opening to allow for an assessment of the airway while the fetus is still attached to placental circulation. This technique has been used as a primary procedure to treat tracheal occlusion, to manage neck masses, and to facilitate the safe delivery of conjoined twins

interventions designed to protect the lungs from the chemical pneumonitis caused by chronic meconium exposure, such as amnioinfusion [ , ] or routine nasopharyngeal suctioning of meconium-stained neonates. [ ] Postterm pregnancy is also an independent risk factor for neonatal encephalopathy [ ] and for death in the first year of life. [ , ] While much of the work above has been conducted in postterm pregnancies. Some of the fetal risks such as presence of meconium, increased risk of neonatal acidemia (...) in utero. Traditionally, saline amnioinfusion and aggressive nasopharyngeal and oropharyngeal suctioning at the perineum were used to decrease the risk of meconium aspiration syndrome. Recent studies contradict this standard practice. Fraser et al performed a prospective, randomized, multicenter study evaluating the risks and benefits of amnioinfusion for the prevention of meconium aspiration syndrome.
