What is the purpose of an amnioinfusion?

Amnioinfusion is being used to treat intrapartum problems known to be associated with fetal compromise, including prophylactic treatment of oligohydramnios during labor and after premature rupture of the membranes, treatment of severe variable decelerations during labor and reducing the risk of meconium aspiration …

When should amnioinfusion be done?

Aetna considers amnioinfusion medically necessary for any of the following indications: Prophylactic treatment of oligohydramnios, or. Reduction of variable decelerations of the fetal heart rate because of cord compression during labor, or.

How do they do amnioinfusion?

Amnioinfusion refers to the instillation of fluid into the amniotic cavity. This procedure is typically performed during labour through an intrauterine pressure catheter introduced transcervically after rupture of the fetal membranes.

What is amnioinfusion in pregnancy?

Amnioinfusion involves infusion of fluid by a needle inserted into the womb and the space surrounding the unborn baby, to increase the amount of amniotic fluid. Introduction.

How successful is amnioinfusion?

An amniotic fluid index of >8 cm before amnioinfusion has less than a 50% chance for success and leads to a high incidence of surgical vaginal deliveries.

What is an amnioinfusion and when is it indicated?

Amnioinfusion is a method in which isotonic fluid is instilled into the uterine cavity. It is primarily used as a treatment in order to correct fetal heart rate changes caused by umbilical cord compression, indicated by variable decelerations seen on cardiotocography.

What is uterine resuscitation?

Intrauterine resuscitation consists of applying specific measures with the aim of increasing oxygen delivery to the placenta and umbilical blood flow, in order to reverse hypoxia and acidosis.

How often is amnioinfusion successful?

Can they replace amniotic fluid?

It is not possible to replace the fluid or repair the hole in the membranes around your baby. You may carry on leaking fluid for the rest of your pregnancy as amniotic fluid continues to be made. However, treatment may be offered to reduce the risk to your baby.

What do you do for intrauterine resuscitation?

They include maternal repositioning, reduction of uterine activity, an intravenous fluid bolus, oxygen administration, correction of maternal hypotension, amnioinfusion, and alteration of second-stage labor pushing efforts.

Amnioinfusion refers to the instillation of fluid into the amniotic cavity. The rationale is that augmenting amniotic fluid volume may decrease or eliminate problems associated with a severe reduction or absence of amniotic fluid, such as severe variable decelerations during labor.

How to obtain informed consent for amnioinfusion?

Amnioinfusion Initiation & Ongoing Management 1. Informed verbal consent must be obtained prior to initiation of amnioinfusion (See IWK Policy #124.1 – Consent to Treatment). Consider language barriers and/or fear when discussing procedure. Inform patient of what to expect with amnioinfusion i.e. leaking of fluid. 2.

When to use amnioinfusion in PPROM pregnancies?

However, amnioinfusion remains a reasonable approach in the treatment of repetitive variable decelerations, regardless of amniotic fluid meconium status. There is evidence supporting the use of amnioinfusion in pregnancies complicated by preterm premature rupture of membranes (pPROM).

When to use amnioinfusion for meconium stained amniotic fluid?

The ACOG Committee on Obstetric Practice (2006) stated that based on available literature, routine prophylactic amnioinfusion for meconium-stained amniotic fluid is not recommended. Prophylactic use of amnioinfusion for meconium-stained amniotic fluid should be performed only in the setting of additional clinical studies.
