Comparison of Combined Spinal-epidural Analgesia Versus Epidural Analgesia for Pain Management During Labor

Not Applicable

• Conditions: Labor Pain; Labor Fetal Anoxia; Labor Long

• Registration Number: NCT03600272
• Lead Sponsor: Deng Dongrui

Brief Summary

The investigators want to compare the safety and efficacy between the combined spinal-epidural analgesia and epidural analgesia during labor.

Detailed Description

Participants who request neuraxial labor analgesia are randomized to receive combined spinal-epidural analgesia or epidural analgesia during labor. The investigators collect the data on the duration of three stages of labor, the mode of delivery, neonatal Apgar scores, VAS scores, modified Bromage scores.

Primary Outcome Measures

Name	Time	Method
Labor duration	At the end of delivery	Duration of three stages of labor

Secondary Outcome Measures

Name	Time	Method
1 minute and 5 minutes Apgar scores	1 min after delivery, 5 min after delivery.	Neonatal Apgar scores at the first and fifth minute.The score indicates the infant s' conditions, including heart rate, breathing, muscle tone, reflex response, color. Each characteristic is given an individual score; two points for each of the five categories if all is completely well; then all scores are totaled. The score is from 0 to 10.
Visual Analogue Scores(VAS)	At 5min before analgesia; at 5min, 15min, 30min, 1h after the first dose of analgesic drugs； at cervical dilation of 3cm , 6cm and 10cm; at the time of birth of infant; at the time of delivery of placenta.	VAS is the most common pain scale for quantification. The score is higher, the patient will be more painful. That will indicate if the analgesia is effective. Visual analog scale (VAS) ranging from 0 to 10 (with 10 representing the worst pain imaginable) to measure the degree of pain for participants.
Modified Bromage scores	At 5min before analgesia; at 5min, 15min, 30min, 1h after the first dose of analgesic drugs； at the cervical dilation of 3cm , 6cm and 10cm; at the time of birth of infant; at the time of delivery of placenta.	The modified Bromage score is the most frequently used measure of motor block. In this scale, the intensity of motor block is assessed by the patient's ability to move their lower extremities(0: no motor paralysis; 1: inability to raise extended leg, but able to move knee and foot; 2: inability to raise extended leg and to move knee, but able to move foot; 3: inability to raise extended leg or to move knee and foot).
The mode of delivery	At the end of delivery	Including spontaneous vaginal delivery, vacuum- and forceps-assisted delivery, cesarean delivery
