fetal immobilization

Pharmacological or mechanical techniques used to prevent fetal movement during surgical procedures to ensure precision and safety.

Full Definition

Fetal immobilization encompasses various methods used to minimize or eliminate fetal movement during surgical interventions. Pharmacological approaches include the administration of neuromuscular blocking agents such as vecuronium or atracurium directly to the fetus via intramuscular injection. Mechanical methods may involve positioning techniques or the use of specialized instruments to stabilize fetal parts. Effective immobilization is crucial for procedures requiring precise instrument placement, such as neural tube defect repairs or cardiac interventions, where unexpected fetal movement could result in injury or procedural failure.

Usage

Usage note: Requires specification of agents used and monitoring protocols.
