Predictive Parameters for Difficult Tracheal Intubation Identification in

Status Completed

Clinical Trial Summary

Clinical Trial Description

Intubation manoeuvres in patients undergoing thyroid surgery might be challenging for anesthesiologist. Thyroid gland enlargement (goiter) or tissue fibrosis (neoplasms) could alter the physiologic anatomy of upper airways and trachea, resulting in compression or dislocation.

There are few scientific data about airway management and thyroid pathology and the incidence of difficult tracheal intubation in this specific kind of patient is largely variable from 0% to 12.9%. These data have been collected from little statistical samples (from 50 to 326 patients), the results aren't always unanimous and a study evaluating simultaneously all the risk factors for difficult intubation does not exist.

We want to evaluate the incidence and identify predictive parameters of difficult intubation in patients undergoing thyroid surgery.

During pre-anesthetic assessment the following data will be collected:

Inter-incisor gap (cm) Mallampati test (1;2;3;4) Thyromental distance (cm) Prognathism (yes; no) Neck motility (<80°;80-90°;>90°) Total body weight (kg) History of difficult tracheal intubation (yes; no) Tracheal deviation at chest X-Ray (yes; no) Neck circumference (cm) Mediastinal goiter (yes; no) Histologic features (benign; carcinoma)

During the post-anesthesia it will be noted down the following:

Cormack scale (1; 2a; 2b; 3; 4) Number of necessary attempts to intubate (1;2;3;…) Time from induction to intubation (min) Necessity to use advanced airway management devices (Frova; Glidescope; Ambu-scope; fiber-optic; other) ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
