Conditions

Health Condition 1: null- All patients for surgery under general anaesthesia requiring intubation.

Interventions

Intervention1: Ultrasound: A SonoSite® MicroMaxx® ultrasound system (SonoSite INC, Bothell, WA). Low frequency curvilinear probe will be used to assess tongue parameters and hyomental distance. Cont

Eligibility

Inclusion criteria

Inclusion criteria: Patients posted for surgery under general anaesthesia requiring endotrachael intubation.

Exclusion criteria

Exclusion criteria: 1) Refusal to participate in the study 2) Patients posted for emergency surgical procedures. 3) Patients with difficulty in mouth opening eg. temporomandibular joint ankylosis. 4) Patients with obvious airway or neck pathology.

Design outcomes

Primary

MeasureTime frame
1)To see whether ratio of volume of tongue to hyomental distance(HMD) in neutral position, hyomental distance in extension (HMDE) as measured by ultrasound(USG) can predict difficult intubation. 2) To observe the predictability of the ratio of tongue thickness and HMD and HMDE measured by USG for difficult intubation. Timepoint: Airway assessment clinically and via ultrasound will be done in the pre operative area. Cormack and Lehane grading will be done during intubation.

Secondary

MeasureTime frame
To see whether the addition of HMDR further increases the efficacy.Timepoint: Airway assessment clinically and via ultrasound will be done in the pre operative area. Cormack and Lehane grading will be done during intubation.
