Dexmedetomidine, Epidural Analgesia, Fentanyl, Levobupivacaine, Painless Labor
Conditions
Brief summary
Central neuraxial analgesia has been extensively used for labor analgesia and is currently the gold standard technique for pain control in obstetrics. The aim of the study will be to compare the role of dexmedetomidine or fentanyl as additives to epidural levobupivacaine in painless vaginal delivery as regard maternal analgesia and safety.
Interventions
The patients will receive 15 ml of 0.125% levobupivacaine.
The patients will receive 13 ml of 0.125% levobupivacaine and 0.5μg/kg dexmedetomidine diluted in 2 ml saline.
The patients will receive 13 ml of 0.125% levobupivacaine and 25μg fentanyl diluted in 2 ml saline.

Study design
Intervention model description
Patients will be randomly allocated into three equal groups by computer generated sequence through sealed opaque envelopes. Each group will include 30 patients. Group C (Control group): Epidural analgesia with levobupivacaine alone Group D (Dexmedetomidine group): Epidural analgesia with levobupivacaine and dexmedetomidine Group F (Fentanyl group): Epidural analgesia with levobupivacaine and fentanyl
Eligibility
Inclusion criteria
* American Society of Anesthesiologists (ASA) physical status class II and III, * Full term pregnancy.
Exclusion criteria
* Patient refusal to epidural analgesia, * Contraindications of epidural analgesia (coagulopathy, local infection, vertebral deformity hypersensitivity to levobupivacaine, dexmedetomidine or fentanyl, hemodynamic instability, severe aortic or mitral stenosis), * Cardiac diseases * Severe pre-eclampsia, * Breech presentations * Antepartum hemorrhage * Cephalopelvic disproportion * Body mass index ≥40 kg/m2.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Duration of maternal analgesia | 24 hours after epidural injection | Duration of analgesia will be assessed by measuring the time between the onset of sensory block and return of pain sensation. If the block is inadequate or the patient has pain, a top up dose of 8 mL of the study medication and local anesthetic will be given when visual analogue scale (VAS) will be ≥ 4. The pain relief will be assessed by the visual analogue scale (VAS) from 0 to 10 (0: no pain, 1-3: mild pain, 4-7: moderate pain, \> 7: severe pain). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Onset of maternal analgesia. | One hour after epidural injection | The onset of analgesia will be defined as the time taken from drug administration to visual analogue scale (VAS) \<3. |
| Complications of drugs of epidural technique | 24 hours after epidural injection | Drugs: Sedation, Bradycardia Epidural anesthesia (including nausea, vomiting, backache and fever) |
