About this study
Official title: Dexmedetomidine , Fentanyl or Nalbuphine As Additives to Epidural Bupivacaine for Labor Analgesia. A Double Blind Randomized Study.
The aim of the study will be to compare the role of Dexmedetomidine, Nalbuphine and fentanyl as additives to epidural bupivacaine in painless vaginal delivery as regard of effectiveness analgesia and maternal safety.
Read the detailed description
Labor pain often causes a strong stress response. Several inhalation and parenteral anesthetics, sedatives, tranquilizers, and analgesics have been used for pain relief during labor, while over the last decade, lumbar epidural analgesia has greatly increased .
Recently, it was concerned by most mothers and doctors that how to alleviate the pain during delivery. The ideal labor analgesia should be based on maternal and child safety and should have a fast acting good analgesic effect and less adverse reaction .
Epidural anesthesia is convenient and has a less adverse reaction and obvious effect in the commonly used analgesic methods, which are widely used in the current way of analgesia .
Studies have confirmed the efficacy of dexmedetomidine in prolonging the duration of perineural nerve blocks. Specifically, perineural dexmedetomidine enhances sensory, motor, and analgesic block characteristics.
Dexmedetomidine is a selective α₂ receptor agonist and has a sympatholytic, sedative, and opioid sparing effect. It does not cause respiratory depression and can therefore be used as an adjuvant in certain clinical settings .
It has also been proved that dexmedetomidine would not increase the risk of side effects, such as nausea, headache, vomiting, shivering, and hypotension .
Nalbuphine is a synthetic agonist-antagonist opioid that has the characteristics of Mu-antagonist and Kappa-agonist activities. Nalbuphine has gained parenteral analgesia for intraoperative, postoperative, and obstetrical uses .
The analgesic potency of nalbuphine has been found to be equal to morphine, but unlike morphine, it shows a ceiling effect on respiratory depression. It has the potential to provide effective postoperative analgesia with no risk of respiratory depression .

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Abanob Fathy Zareef, MBBS (01010424707, bebofathy47@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
VAS score for pain (time frame: before epidural analgesia, 30 minutes from time 0, at 1 hour and hourly till end of 3rd stage of delivery.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
