Labor Pain Disease Summary

Overview

Labor pain is defined as the pain experienced during labor that varies in intensity, primarily resulting from responses to allogenic stimuli during labor.
Labor pain experience is highly individualized and will depend on a woman's emotional, motivational, cognitive, cultural and social circumstances.
The pain felt during the 1st stage of labor originates from the rhythmic contractions of the lower uterine segment and progressive cervical dilation mediated via T10-L1 spinal nerves, while the pain in the 2nd stage of labor is more intense due to stretching of the vagina, vulva and perineum as the fetus descends in the birth canal superimposed by the pain of uterine contractions, and is transmitted through the S2-S4 spinal segments.
Selected analgesia technique will depend on the patient’s wishes, medical status, progress of labor and facility resources.
