GTN Nitroglycerin for Emergency Cervico-Uterine Relaxation, Obstetrics

exp date isn't null, but text field is

Abstract

Rapid and transient relaxation of the cervix and uterus is occasionally required to allow obstetric manoeuvres during emergencies.

A number of case reports and trials have shown nitroglycerin (Glyceryl Trinitrate) to provide rapid and transient cervico-uterine relaxation (albeit unlicensed).

The therapeutic effect is seen within 1-2 minutes of administration and lasts for 3-5 minutes.
