Correlation of Neck Circumference With Difficult Mask Ventilation and Difficult Laryngoscopy in Morbidly Obese Patients
- Conditions
- Morbid Obesity
- Registration Number
- NCT02589015
- Lead Sponsor
- Istanbul University
- Brief Summary
The aim of this study is to determine the correlation of neck circumference with difficult mask ventilation and laryngoscopy in morbidly obese patients.
- Detailed Description
Patients' Mallampati score, upper lip bite test, neck mobility, teeth abnormalities were evaluated preoperatively. Mouth opening, sternomental and thyromental distances, neck circumference, thoracic circumference, breast circumference , belly circumference and hip circumference were measured preoperatively.
After anesthesia induciton with propofol and rocuronium, patients' mask ventilation difficulty was evaluated as defined below: V1- Ventilated by single anesthesist easily; V2- Ventilated by single anesthesist with oral airway; V3- Ventilated by two anesthesists; V4- Unable to mask ventilate. V3 and V4 was defined as difficult mask ventilation.
Laringoscopy was performed with MacIntosh laryngoscop and Cormack Lehane (CL) score was evaluated. CL score III and IV were defined as difficult laryngoscopy.
