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.

Conditions

Morbid Obesity

Keywords

morbid obesity; neck circumference; difficult mask ventilation; difficult laryngoscopy

Outcome Measures

Primary Outcomes (2)

• Correlation of difficult laryngoscopy with neck circumference

  Cormack Lehane scores III and IV were defined as difficult laryngoscopy.

  Cormack Lehane score was assessed during laryngoscopy

• Correlation of difficult mask ventilation with neck circumference

  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.

  Ventilation difficulty scale was assessed during mask ventilation

Secondary Outcomes (20)

• Correlation of difficult laryngoscopy with modified mallampati score

  Cormack Lehane score was assessed during laryngoscopy

• Correlation of difficult mask ventilation with modified mallampati score

  Ventilation difficulty scale was assessed after during mask ventilation

• Correlation of difficult laryngoscopy with neck movement

  Cormack Lehane score was assessed during laryngoscopy

• with neck movement

  Ventilation difficulty scale was assessed during mask ventilation

• Correlation of difficult laryngoscopy with dentition

  Cormack Lehane score was assessed during laryngoscopy
