Use of propranolol in dysfunctional labour
British Journal of Obstetrics and Gynaecology
|August 1, 1975
Summary
Fear and anxiety during labor increase catecholamines, causing weak contractions. Intravenous propranolol (a beta-blocker) effectively treated dysfunctional labor in ten women, leading to normal delivery without complications.
Area of Science:
- Obstetrics and Gynecology
- Pharmacology
Background:
- Fear and anxiety during labor elevate catecholamine levels.
- Elevated catecholamines can stimulate uterine adrenergic beta receptors, leading to dysfunctional labor and weak contractions.
Purpose of the Study:
- To investigate the efficacy of intravenous propranolol in treating dysfunctional labor.
- To assess maternal and fetal outcomes following propranolol administration for labor dysfunction.
Main Methods:
- Ten primigravidae experiencing typical dysfunctional labor were administered intravenous propranolol.
- Uterine activity, labor progression, and maternal/fetal outcomes were monitored.
Main Results:
- Intravenous propranolol administration was followed by a prompt return to normal uterine activity.
- All ten participants experienced normal vaginal delivery without significant maternal or fetal complications.
Conclusions:
- Intravenous propranolol is a potentially effective treatment for dysfunctional labor.
- This preliminary study suggests a novel therapeutic approach for managing labor dystocia with encouraging safety and efficacy.
