Pronunciation: toh-KAHL-ih-sis
Medical suppression of uterine contractions to prevent preterm labor following fetal surgery.
Full Definition
Tocolysis refers to the pharmacological inhibition of uterine contractions to prevent or delay preterm labor. In fetal surgery, tocolytic agents are routinely used perioperatively to minimize uterine irritability caused by surgical manipulation. Common tocolytic medications include indomethacin, magnesium sulfate, and calcium channel blockers. Effective tocolysis is essential for maintaining pregnancy to term after fetal intervention.
