About this study
Official title: Superior Laryngeal Nerve Block Versus Sedation with Intravenous Dexmedetomidine Infusion for Awake Fiberoptic Intubation of Hemimandibulectomy Patients with an Anticipated Difficult Airway: a Randomized Controlled Trial
This study compares the efficacy and safety of dexmedetomidine infusion versus superior laryngeal nerve block during awake fiberoptic intubation in hemimandibulectomy patients.
- Conditions
- Superior Laryngeal Nerve Block, Sedation, Dexmedetomidine, Awake Fiberoptic Intubation, Hemimandibulectomy, Anticipated Difficult Airway

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexmedetomidineDrug
Also called Sedation arm
The patients were given 0.5 mcg /kg dexmedetomidine over 10 min via syringe pump, followed by 0.2-0.7 mcg/kg/hour until the end of intubation according to hemodynamics.
Superior laryngeal nerve blockDrug
Also called Nerve Block arm
The patients received an airway nerve block through bilateral superior laryngeal nerve block and trans-tracheal injection for recurrent laryngeal nerve.
| Study group | Role | What they receive |
|---|---|---|
| Dexmedetomidine group | Experimental | Patients were given 0.5 mcg/kg of dexmedetomidine over 10 minutes via a syringe pump, followed by a maintenance dose of 0.2-0.7 mcg/kg/hour until the end of intubation based on Hemodynamics. Receives: Drug: Dexmedetomidine |
| Superior laryngeal nerve block group | Active comparator | Patients received an airway nerve block through bilateral superior laryngeal nerve block and trans-tracheal injection for recurrent laryngeal nerve. Receives: Drug: Superior laryngeal nerve block |
What is being measured
The primary outcome is the main question the study is designed to answer.
The intubation score
The intubation conditions score is assessed based on the following criteria:
(i) Vocal movement: 1 = open, 2 = moving, 3 = closing, 4 = closed. (ii) Coughing: 1 = none, 2 = slight, 3 = moderate, 4 = severe. (iii) Limb movement: 1 = none, 2 = slight, 3 = moderate, 4 = severe.
Where The Intubation conditions score is :
Excellent = 1 when all qualities are excellent. Good = 2 when all qualities are either excellent or good. Poor = 3 when the presence of a single poor quality is noted.
Measured: time from introduction of scope of fibroptic device in the mouth of the patient to the insertion of the endotracheal tube between the vocal cords.Time range of 10 minutes
Secondary outcomes (7)
The degree of comfort
The comfort score was evaluated using a five-point fiberoptic intubation comfort scale: 1 = no reaction, 2 = slight grimace, 3 = heavy grimace, 4 = verbal objection, and 5 = defensive movement of head and hands.
Measured: time from introduction of scope of fibroptic device in the mouth of the patient to the insertion of the endotracheal tube between the vocal cords. Time range of 10 minutes
Degree of airway obstruction
The degree of airway obstruction (1 - absent, 2 - requiring neck extension, 3 - requiring jaw thrust) was noted
Measured: time from introduction of scope of fibroptic device in the mouth of the patient to the insertion of the endotracheal tube between the vocal cords Time range of 10 minutes
Heart rate
Heart rate is recorded at 1-minute intervals until intubation is completed, followed by measurements every two minutes until 10 minutes after intubation.
Measured: From one minute before intubation to 10 minutes after intubation
Mean arterial pressure
Mean arterial blood pressure is recorded at 1-minute intervals until intubation is completed, followed by measurements every two minutes until 10 minutes after intubation.
Measured: From one minute before intubation till10 minutes after intubation
Ramsay sedation score
Ramsay sedation score was recorded as follows: 1: Awake, agitated or restless or both; 2: Awake, cooperative, oriented, and tranquil; 3: Awake but responds to commands only; 4: Asleep, with a brisk response to a light glabellar tap or loud auditory stimulus.
Measured: From time of injection of Drugs (Dexetodomidine , Lidocaine) to the patient to 10 minutes after intubation
Patient satisfaction score
The patient satisfaction score (1-excellent, 2-good, 3-reasonable, 4-poor) was documented.
Measured: From the end of the operation to 24 hours postoperative
Incidence of complications
Adverse events such as bradycardia, hypotension, nausea, vomiting, pruritus, respiratory depression, O2 desaturation, or any other complications were recorded.
Measured: From the end of the operation to 24 hours postoperative

Questions about this trial
What is this clinical trial studying?
A study testing Dexmedetomidine and Superior laryngeal nerve block in people with Superior Laryngeal Nerve Block and Sedation, run by Cairo 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 5 inclusion and 7 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 23 Oct 2024. 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.
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 intubation score (time frame: time from introduction of scope of fibroptic device in the mouth of the patient to the insertion of the endotracheal tube between the vocal cords.Time range of 10 minutes). 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 2024; AzTrials last refreshed its copy on 7 Nov 2026.
