About this study
Official title: Comparison Among Three Different Video Scope Guided Nasotracheal Intubation: a Prospective, Non-randomised Controlled Trial
Nasotracheal intubation (NTI) has become the most optimal alternative to oral endotracheal intubation for oro-maxillofacial surgery because it can offer an excellent vision field of the mouth. Additional benefits include milder oropharynx stimulation, less airway secretions, and better tolerance for long term endotracheal intubation maintenance. Traditional NTI is performed under the guidance of indirect laryngoscope, which is often accompanied by longer maneuver time and adverse complications such as trauma and bleeding. The development of various visualization tools such as video laryngoscope, video fiberoptic scope and video rigid laryngoscope has greatly improved NTI. However, there is no consensus on which one is the best adjunctive device for NTI. Therefore, a study on a comparison of the clinical efficacy of the above three video scope guided methods for NTI will be conducted.
Read the detailed description
A total of 60 eligible patients will be enrolled in this prospective study, they are scheduled to undergo elective oro-maxillofacial surgeries under general anaesthesia with nasotracheal intubation in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. According to the kinds of video methods uesd to assist in nasotracheal intubation, patients will be randomly divided into video laryngoscope group, video fiberoptic scope group and video rigid laryngoscope group, 20 participants in each group. The data of the duration of catheter reaching oropharynx (T1), the duration of catheter reaching glottis (T2), successful intubation time (T3), the first-attempt intubation success rate, the total number of intubations for each participant, whether there is oral and nasal mucosa bleeding, whether the tracheal ring is pressed, whether the catheter is rotated, the heraodynamic changes, and the occurrence of throat complications within 2 hours after surgery, will be recorded respectively.

| Study group | Role | What they receive |
|---|---|---|
| video rigid laryngoscope group | Experimental | Similarly during intubation, the patient should be placed in the supine position with the neutral head. The endoscopic body of video rigid laryngoscope covered by a lubricated endotracheal tube enters the airway through the nasal cavity, then proceeds under visual conditions. When the epiglottis is exposed, if necessary, gently lift the patient's lower jaw so that the glottis is fully visible. The tube is pushed to approach and pass the glottis. Withdraw the endoscopic body while adjusting the depth of tube in the trachea. The intubation ends with tube fixation. Receives: Behavioral: video rigid laryngoscope guided nasotracheal intubation |
| video laryngoscope group | Experimental | First of all, participants will be asked to take supine position with neutral head. The operator will insert a lubricated endotracheal tube through the nasal cavity into the oropharynx, while he/she holds the handle of video laryngoscope in his/her left hand. Laryngoscope blade can be placed into oral cavity along the right corner of the patient's mouth, and the tongue is pushed to the left by moving the handle. Blade should arrive at a suitable depth to fully expose the epiglottis and glottis. After that, the operator can push the catheter with the right hand to approach and pass the glottis, sometimes Magill forceps are necessary. Finally, the tube is inserted into the trachea to the appropriate depth and fixed firmly. Receives: Behavioral: video laryngoscope guided nasotracheal intubation |
| video fiberoptic scope group | Experimental | It is suggested to apply paraffin oil to the surface of the insertion tube of video fiberoptic scope, where the friction with the inner wall of the endotracheal catheter will be reduced. The insertion tube together with a lubricated endotracheal tube will be placed into the nasopharynx through the nasal cavity of patient who takes supine position with neutral head. Push the insertion tube slowly and continuously along the airway until cuff passes through the glottis. Next carefully, the endotracheal tube can be delivered into the trachea, and the insertion tube can be withdrawn from the trachea. At last, the tracheal catheter can be fixed after the depth is adjusted to an appropriate level. Receives: Behavioral: video fiberoptic scope guided nasotracheal intubation |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Nasotracheal intubation (NTI) has become the most optimal alternative to oral endotracheal intubation for oro-maxillofacial surgery because it can offer an excellent vision field of the mouth. Additional benefits include milder oropharynx stimulation, less airway secretions, and better tolerance for long term endotracheal intubation maintenance. Traditional NTI is performed under the guidance of indirect laryngoscope, which is often accompanied by longer maneuver time and adverse complications such as trauma and bleeding. The development of various visualization tools such as video laryngoscope, video fiberoptic scope and video rigid laryngoscope has greatly improved NTI. However, there is no consensus on which one is the best adjunctive device for NTI. Therefore, a study on a comparison of the clinical efficacy of the above three video scope guided methods for NTI will be conducted.

Questions about this trial
What is this clinical trial studying?
A study testing video laryngoscope guided nasotracheal intubation, video rigid laryngoscope guided nasotracheal intubation and video fiberoptic scope guided nasotracheal intubation in people with Intubation, Intratracheal and Airway Management, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.
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 6 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 18 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Zhilin Wu, MD, PhD. (18963946992, 840916@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the duration of catheter reaching oropharynx (time frame: within 1 minute). The study lists 5 primary outcomes in all. 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 NCT05534451, which also lists 7 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 18 Aug 2023.
