Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the incidence of lingual nerve injury and related factors in difficult intubation cases.

Demographic data of difficult intubation cases and body mass indices, thyromental and sternomental distances, mallampati classification, neck circumference, maximum mouth opening be recorded.Numbness of the tongue and metallic taste will be questioned

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The lingual nerve is the anterior descending branch of the posterior trunk of the mandibular division of the trigeminal nerve.

Lingual nerve injury is a recognised complication of orotracheal intubation and has been associated with forceful laryngoscopy.

Although left-sided neuropraxia has been reported, right-sided lesions are thought to be more common because the standard Macintosh laryngoscope exerts pressure on the right side of the tongue.

Lingual nerve injury following orotracheal intubation was first described in 1971 by Teichner who reported a right-sided neuropraxia which was attributed to direct pressure from the laryngoscope.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Difficult intubation group

An intubation is called difficult if a normally trained anesthesiologist needs more than 3 attempts or more than 10 min for a successful endotracheal intubation.

Observational

Intervention Type OTHER

No intervention

Non difficult intubation group

An intubation is called non difficult if a normally trained anesthesiologist needs only one attempt for a successful endotracheal intubation.

Observational

Intervention Type OTHER

No intervention

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

All adult patients undergo general anesthesia who have difficulty in intubation will be included in the study. The same number of patients without intubation difficulties will be included in the study as a control group.

Exclusion Criteria

1. Patients who are not intubated under general anesthesia
2. Patients undergoing regional anesthesia or peripheral nerve block
3. Patients with laryngeal mask placed will not be included in the study.
