About this study
Spinal anesthesia is the most commonly used technique for lower abdominal surgeries as it is very economical and easy to administer. However, postoperative pain control is a major problem because spinal anesthesia using only local anesthetics is associated with relatively short duration of action, and thus early analgesic intervention is needed in the postoperative period The transversus abdominus plane (TAP) block is a regional analgesic technique which blocks T6-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries
- Being tested
- Dexmedetomidine
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexmedetomidineDrug
60 Patients will be randomly divided into three equal groups:
Group A (n=20) : spinal anesthesia with Dexmedetomidine (5µg ) added to local anesthetic (bupivacaine Hcl ) (10 mg) given intrathecally .
Group B (n=20) : spinal anesthesia using local anesthetic( bupivacaine Hcl) (20 mg) combined with TAP block using Dexmedetomidine (20µg ) after the cesarean section
Group C (n=20) (controlled group ) : Spinal anesthesia using only local anesthetic (bupivacaine Hcl ) (10 mg) .
| Study group | Role | What they receive |
|---|---|---|
| Group A (spinal Dexmedetomidine) | Active comparator | . Spinal needles (22 G) will be introduced in sitting position after skin disinfection with povidine iodine, iliac crest will be palpated and thumb extended to meet the midline, feeling the space between L4 and L5. spinal needle penetrates through the dura matter, a pop will be felt and then after the needle puncture into the subarachnoid space and the appearance of clear cerebrospinal fluid, the intrathecal local anesthetic will be injected. All patients will be receiving 2 ml heavy bupivacaine 0.5% plus 5 µg dexmedetomidine to total volume of 2.5 ml. Receives: Drug: Dexmedetomidine |
| Group B (spinal with transversus abdominus plane block) | Active comparator | Spinal needles (22 G) introduced in sitting position . patients receiving1.7 to 2.2 ml heavy bupivacaine 0.5%( according to weight and height ) + 1 ml normal saline = total volume of 2.5 ml then at surgery end under sonographic guide transducer placed in transverse plane above iliac crest.A 90 mm 22 G short beveled block needle inserted in-plane with transducer, in anterior-posterior direction. needle connected to syringe contains20 ml of bupivacaine 0.25%+10 µg dexmedetomidine to deposit local anesthetic deep into the fascial layer between internal oblique \& transversus abdominis muscles on each side. Receives: Drug: Dexmedetomidine |
| Group C ( controlled group ) Spinal Anesthesia only : | Active comparator | Patients will be anesthetized only with spinal anesthesia using Bupivacaine Hcl( 10 mg). Receives: Drug: Dexmedetomidine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Analgesic efficacy of both routes
Demographic data (age, weight, and length), mean arterial blood pressure (MAP), and heart rate (HR) will be measured every 5 minutes intraoperatively and at 1, 2, 4, 6, 8,12,16,20 and 24 h postoperatively. Visual analog pain score (VAS) between 0 and 10 (0=no pain, 1-3=mild pain, 4-6=moderate pain, and 7-10=severe pain) will be recorded at 1, 2, 4, 6, 8,16,20 and 24 h postoperatively. First time of rescue analgesia: this is defined as the time from onset of sensory block till the time of first requirement of analgesia. The total amount of rescue analgesia consumption in the form of intravenous ketorolac→0.5 mg/kg if VAS greater than or equal to 4. Any undesirable postoperative side effects (as nausea, vomiting and pruritus) will be recorded and managed.
Measured: 24 hours
Secondary outcomes (1)
1. Hemodynamic effect on the patient
measuring BP , HR , oxygen saturation during operation every 5 minutes
Measured: 1 hour

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Analgesic efficacy of both routes (time frame: 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04969705, which also lists 3 linked publications.
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 1 Jul 2022.
