About this study
Our scientific work aimed to evaluate the analgesic efficacy of dexmedetomidine as an adjuvant to erector spinae plane block versus subcostal transverse abdominis plane block in patients undergoing laparoscopic cholecystectomy.
Read the detailed description
Laparoscopic cholecystectomy (LC) is the most commonly performed surgical procedure for the management of cholelithiasis. Acute pain after LC consists of somatic, parietal, and referred pain caused by trocar insertion, gall bladder resection, carbon dioxide insufflation, and other factors.
The subcostal transverse abdominis plane (SCTAP) block is the deposition of local anesthetic in the transverse abdominis plane inferior and parallel to the costal margin.
Ultrasound-guided erector spinae plane block (ESPB) is a popular, interfascial regional technique initially described for managing thoracic neuropathic pain.
Dexmedetomidine is an alpha-2 adrenergic receptor agonist that has been the focus of interest due to its sedative, analgesic, perioperative sympatholytic, and cardiovascular-stabilizing effects, resulting in reduced anesthetic requirements.

| Study group | Role | What they receive |
|---|---|---|
| Group I | Experimental | Patients received an ultrasound-guided subcostal transverse abdominis plane block with injection of 10 ml bupivacaine 0.25 %, 5ml lignocaine 2 % plus 0.5 μg/kg dexmedetomidine in a 20 ml volume. Receives: Other: Subcostal transverse abdominis plane block |

What is being measured
The primary outcome is the main question the study is designed to answer.
Total dose of morphine consumption
If the Visual analogue scale (VAS) is ≥ 3, IV morphine was given as a bolus of 2 mg (body weight < or = 60 kg) or 3 mg (body weight > 60 kg) with 5 minutes' lockout interval.
Measured: 24 hours postoperatively
Secondary outcomes (7)
Heart rate
Heart rate was recorded at baseline, after injection then every 30 minutes till the end of surgery and after surgery at 0, 2, 4, 6, 8, 12, 16 and 24 h.
Measured: 24 hours postoperatively
Mean arterial pressure
Mean arterial pressure was recorded at baseline, after injection then every 30 minutes till the end of surgery and after surgery at 0, 2, 4, 6, 8, 12, 16 and 24 h.
Measured: 24 hours postoperatively
Intraoperative opioid consumption
Intraoperative opioid consumption was recorded.
Measured: Intraoperatively
Time to first rescue analgesia
Time to first rescue analgesia was recorded from the end of surgery till first dose of morphine administrated.
Measured: 24 hours postoperatively
Degree of pain
Visual analogue scale (VAS) was assessed after surgery at 0, 2, 4, 6, 8, 12, 16, 18, and 24 h [where (0 = no pain and 10 = severe pain)].
Measured: 24 hours postoperatively
Incidence of complications
Incidence of complications such as pneumothorax, local anesthetic systemic toxicity (LAST), bradycardia, hypotension, nausea, vomiting, and failed block were recorded.
Measured: 24 hours postoperatively
Patient satisfaction
Degree of patient satisfaction will be assessed on a 3-point scale; (1= Unsatisfied, 2= neither satisfied nor unsatisfied, 3= satisfied).
Measured: 24 hours postoperatively

The record says: finished, as of the sponsor's last update on 23 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
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?

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?
Total dose of morphine consumption (time frame: 24 hours postoperatively). 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 23 Oct 2026.
