Post-tonsillectomy AnalgesiaPhase 1/2NCT04113720
Levobupivacaine vs Levobupivacaine + Dexmedetomidine Infiltration for Post-tonsillectomy Analgesia and Laryngospasm in Pediatric Patients
A Phase 1/2 study testing Levobupivacaine hydrochloride and Levobupivacaine Hydrochloride + Dexmedetomidine in people with Post-tonsillectomy Analgesia and Levobupivacaine, run by Assiut University at 1 site in Egypt.
Trial summary
Tonsillectomy is one of the most common surgical performed procedures in children. Adenotonsillectomy surgery in pediatrics is commonly managed as an ambulatory surgery. This may be attributed to the use of the electro-dissection surgical technique that decreases the incidence of immediate postoperative hemorrhage. Read more about this study

About this study
Official title: The Effects of Levobupivacaine Versus Levobupivacaine Plus Dexmedetomidine Infiltration for Post-tonsillectomy Analgesia and Laryngospasm in Pediatric Patients
Tonsillectomy is one of the most common surgical performed procedures in children. Adenotonsillectomy surgery in pediatrics is commonly managed as an ambulatory surgery. This may be attributed to the use of the electro-dissection surgical technique that decreases the incidence of immediate postoperative hemorrhage. However, the use of the electro-cautery technique increases postoperative inflammation. Postoperative throat pain is a very important and significant problem because it can lead to decreased oral intake and dehydration with subsequent serious complications of dehydration.
Read the detailed description
The idea behind the use of local anesthetic agents in the peri-operative period is not only related to its ability to block peripheral nociceptor transmission after tissue damage but also in preventing sensitization of the central nervous system. Levobupivacaine is new, long-acting bupivacaine, amide-type local anesthetic and is thought to be less cardio and neurotoxic. However, few studies showed that local infiltration of levobupivacaine reduces the intensity of postoperative pain. Dexmedetomidine is a highly selective α2-adrenoceptor agonist recently introduced to anesthesia practice producing dose-dependent sedation, anxiolysis, and analgesia (involving spinal and supraspinal sites), without respiratory depression. Dexmedetomidine is being used off-label as an adjunctive agent in pediatric patients for sedation and analgesia; in the critical care unit, during non-invasive ( Magnetic resonance imaging) and invasive procedures ( cardiac catheterization and endoscopy). It may also decrease opioid usage and anesthesia requirements as seen from adult data prevent emergence delirium and postanesthesia shivering.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Levobupivacaine hydrochloride and Levobupivacaine Hydrochloride + Dexmedetomidine in people with Post-tonsillectomy Analgesia and Levobupivacaine, run by Assiut University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Nov 2021. 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?
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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
the first call for rescue analgesia (time frame: in 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 NCT04113720, which also lists 4 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 22 Nov 2021; AzTrials last refreshed its copy on 8 Nov 2026.
