A study to compare two laryngoscopes, Macintosh and Airtraq to evaluate the movements of cervical spine while intubating.

Not yet recruiting

Conditions: Diseases of the musculoskeletal system and connective tissue,

Registration Number: CTRI/2020/05/024961

Lead Sponsor: Department of Anaesthesiology and critical care

Brief Summary: The presentprospective study will be conducted in Department of Anaesthesiology & Critical care,Pt. B.D. Sharma, PGIMS, Rohtak. A total of 25 patients, between age group of18-60 years belonging to ASA grade I and II, scheduledfor elective surgery under image control requiring general anaesthesia andintubation, will be enrolled in the study. Patients with cervical spineinjury, RheumatoidArthritis, Scoliosis/spinal deformity, anticipateddifficult intubation, aspirationrisk, pregnancy, BMI> 30kg/m2 will be excluded from the study. On arrivalin the operation theatre baseline readings of electrocardiography (ECG), pulseoximetry (SPO2)), non-invasive blood pressure (NIBP) will be recorded. Baseline image of lateral view of cervical spineincluding first 4 cervical vertebrae will be taken. First laryngoscopy wasperformed using Macintosh laryngoscope and second X-Ray image of lateralcervical spine was taken. Second laryngoscopy was done using Airtraqlaryngoscope and third image of cervical spine radiograph will be taken.Simultaneously the laryngeal view based on modified Cormack and Lehane criteriaand laryngoscopy time will be noted using both the laryngoscopes. All the three radiographs were analysed and anglemeasurements from C0-C4 will be done to evaluate the cervical spine movement. Inaddition, Atlanto-occipitaldistance, anterior deviation of spine and soft tissue displacement duringlaryngoscopy, was also calculated from radiographs. MAP, HR andSpO2 will be recorded before induction and immediately after bothlaryngoscopies.

Study & Design

Study Type: Observational

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
1.Analysis of radioimages: Atlanto occipital distance, difference between the angles made by the cervical spine, Anterior deviation of the spine, Soft tissue displacement will be measured.	The outcome will be assessed on Day 1 of the study. It takes 30 mins to record the data and 1 week to analyze the data.
The following will be assessed for both Macintosh and Airtraq laryngoscopes.Data will be compiled and appropriate statistical test will be used to analyze the results.	The outcome will be assessed on Day 1 of the study. It takes 30 mins to record the data and 1 week to analyze the data.

Secondary Outcome Measures

Name	Time	Method
1.Laryngocopic time	2. Cormack Lehanne grading
