Brief Summary

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

The airflow moving from mouth to the lungs, which can be measured by pulmonary function tests, may be affected by the anatomic disorders of the upper airway. Difficult airway can be considered as the anatomic disorder of the upper airway as well. Therefore, there can be a relationship between difficult airway and pulmonary function tests. The purpose of this study is to elucidate the association between the pulmonary function tests and difficult airway.

Detailed Description

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

After approval of the Gaziosmanpasa University Clinical Trials Ethics Committee, patients those admitted to the anesthesiology outpatient unit will informed about the study. And pulmonary function tests by using Spirodoc® will be performed to those willing to participate in the study. Measurements of the pulmonary function tests, and measurements belong to difficult airway will be recorded.

In the operating theatre, after induction of anesthesia, the difficult intubation measurements will be recorded.

Normality and variance will be tested using One Sample Kolmogorov-Smirnov test, skewness, kurtosis and histograms for each variable. Quantitative data will present as means and standard deviation, and qualitative data as frequency and percentage. Depending on these results, Spearman's correlation analysis will perform to show the association between pulmonary function tests and difficult airway measurements. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL), version 20.0. Statistical significance for all analyses was set at p \< 0.05.
