简要总结
pre anesthetic evaluation of the airway will be done prior to the surgery. patient airway will be assessed by the conventional factors in grp 1 and by ultrasound in grp 2.
following bed side screening test used for airway assessment in grp 1 :
- modified mallampati score
2.neck circumference.
3.Thyromental distance.
Following ultrasoun parameters used in group 2 :
- tongue base thickness.
2.anterior neck soft tissue at the level of hyoid bone.
3.anterior neck soft tissue at the level of epiglottis.
4.anterior neck soft tissue at the level of vocal cords.
after Airway assessment, patient is induced with fentanyl 2-3mcg/kg and propofol 2mg/kg and Rocuronium 0.6mg/kg.
Direct laryngoscopy performed by senior anesthetist who will be blinded to the pre operative airway assessment and Cormack lehane grade noted.
After intubation patient is attached to the ventilator and anesthesia is maintained by inhalational agent and fresh gas flow of 2l/min.
