Clinical Trial Summary

The aim of this study is to compare epidural dexmedetomidine vs nalbuphine added to bupivacaine in labor analgesia and determine the privilege of one over the other and to compare the effect of both analgesics after delivery.


Description:

Labor pain often causes a strong stress response in women. Recently, it is concerned by most mothers and doctors that how to effectively alleviate the pain during delivery. There is no standard treatment for labor pain. A wide range of pharmacological and non-pharmacological labor pain relief techniques are available for pregnant women . Labor analgesia, also known as painless childbirth, refers to the use of various methods to reduce maternal labor pain or make it disappear. The ideal labor analgesia should be based on maternal and child safety, and should have fast acting, good analgesic effect and less adverse reaction. Epidural block anesthesia is convenient, and has less adverse reaction and obvious effect in the commonly used analgesic methods, which is widely used in the current way of analgesia. Dexmedetomidine is a highly selective α2 adrenergic receptor agonist that has sedative, hypnotic, and analgesic effects . Nalbuphine is a synthetic agonist antagoLabor pain often causes a strong stress response in women.

Intervention

Drug:
Dexmedetomidine
Dexmedetomidine, a highly selective a2 receptor agonist, has a sympatholytic, sedative and opioid sparing effect.
Nalbuphine
Nalbuphine, a derivative of 14-hydroxymorphine is a strong analgesic with mixed k agonist and µ antagonist properties. The analgesic potency of nalbuphine has been found to be equal to morphine

Outcome

Type Measure Description Time frame Safety issue
Primary change in VAS score for pain before analgesia and every 30 minutes after analgesia The visual analog scale (VAS) is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity along a 100 mm (10 cm) horizontal line, and this rating is then measured from the left edge (=VAS score). The VAS score correlates well with acute pain levels (Myles et al., 1999). Using a ruler, the score is determined by measuring the distance (cm) on the 10-cm line between the no pain anchor and the patients mark, providing a range of scores from 010. A higher score indicates greater pain intensity. before analgesia and 30 minutes after analgesia and then every 30 minute as long as the epidural catheter is inserted (up to 360 minutes)
Secondary change in Heart rate before analgesia and every 30 minutes after analgesia Monitored and recorded before analgesia and 30 minutes after analgesia and then every 30 minute as long as the epidural catheter is inserted (up to 360 minutes)
Secondary change in arterial blood pressure before analgesia and every 30 minutes after analgesia Monitored and recorded before analgesia and 30 minutes after analgesia and then every 30 minute as long as the epidural catheter is inserted (up to 360 minutes)
Secondary change in SpO2 before analgesia and every 30 minutes after analgesia Monitored and recorded before analgesia and 30 minutes after analgesia and then every 30 minute as long as the epidural catheter is inserted (up to 360 minutes)
Secondary Duration of active phase of 1st stage of labor The duration of active phase of 1st stage of labor varies from one to the other from 100 minutes to 300 minutes
Secondary Duration of 2nd stage of labor The duration of 2nd stage of labor varies from one to the other from 30 minutes to 200 minutes
Secondary Duration of 3rd stage of labor The duration of 3rd stage of labor varies from one to the other from 5 minutes to 15 minutes
Secondary Neonatal condition: APGAR score at 1 and 5 min after the birth to check if any of the study drugs can deteriorate the neonatal condition At 1 minute and 5 minutes after birth
Secondary The adverse reactions: itching, nausea, vomiting, bradycardia and hypotension These adverse reaction can occur after administration of the interventional drugs As long as the epidural catheter is inserted (up to 360 minutes)
