简要总结
According to Americal Society of Anaesthesiologists (ASA), difficult airway is the clinical situation in which a conventionally trained anaesthesiologist experiences difficulty with mask ventillation, difficulty with tracheal intubation, or both.
ASA defines difficult endotracheal intubation as proper insertion of the tracheal tube with conventional laryngoscopy requires more than three attempts or more than 10 minutes.
Operating room cases involving the removal of goiters falls within the difficult airway classificaton. Goiters often involve a number of anatomical locations and results in many implications to the airway and vascular structures. This can lead to upper and lowerairway obstruction, laryngeal malacia, lymphatic and vascular congestion causing edemathat will further compromise the patient’s airway.
Keeping in view the difficult airway due to enlarged thyroid swelling, the present study is being done as comparative study between Macintosh laryngoscope and Airtraq video laryngocscope for thyroid swelling has not been done so far.
patients will be divided randomly into two groups. preoperatively proper airway assessment and complete systemic examination will be done. written and explained consent will be taken. patients in both groups will be given Fentanyl at 2mcg/kg body weight before induction and will be induced with Propofol at 2mg/kg body weight. after checking for bag and mask ventillation succinylcholine will be given at 2mg/kg body weight. after 1 min of ventillation patient will be intubated with any of the two mentioned methods with an armoured endotracheal tube of appropriate size. then the assessment will be made regarding:
-
time of successful intubation
-
ease of intubation
-
percentage of glottic opening
-
modified Cormack and Lehane grading
-
change in vitals
-
post operative upper airway symptoms
