研究概览
简要总结
The present study will be conducted in the department of Anaesthesia at Dr Rajendra Prasad Govt Medical College Tanda. Allthe patients will have full airway assessment during the preanaesthetic checkup ie mouthopening ,modified mallampati scoring ,thyromental distance ,neck movements. Thepatients not meeting inclusion criteria will be excluded from study and theenrolled patients will undergo sonographic assessment of airway by theanesthesiologist inthe pre-operative holding area. The ultrasound view of the airway of all studypatients will be assessed either with ahigh frequency linear probe (A SonoSite® MicroMaxx® ultrasound system (SonoSiteINC, Bothell, WA) or a low frequency curvilinear probe. Various parameters assessed clinically will be corelated with cormack and lehane grading during intubation.

结局指标
主要结局
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.
时间窗: Airway assessment clinically and via ultrasound will be done in the pre operative area. Cormack and Lehane grading will be done during intubation.
2) To observe the predictability of the ratio of tongue thickness and HMD and HMDE measured by USG for difficult intubation.
时间窗: Airway assessment clinically and via ultrasound will be done in the pre operative area. Cormack and Lehane grading will be done during intubation.
次要结局
- To see whether the addition of HMDR further increases the efficacy.(Airway assessment clinically and via ultrasound will be done in the pre operative area. Cormack and Lehane grading will be done during intubation.)
