Comparison of hemodynamic stress response to blind tracheal intubation through two supraglottic devices, Air-Q and I-gel in patients undergoing elective surgery under general anesthesia
Abhilasha Tyagi, Rajender Kumar

Background: The aim of this study is to compare hemodynamic stress response to blind tracheal intubation through two supraglottic devices, Air-Q and I-gel in patients undergoing elective surgery under general anesthesia. Methods: This randomised single blind study was conducted on 90 patients of age 18-60 years, undergoing elective surgery under general anaesthesia. Patients were randomly allocated in two groups-Group I: Air-Q (n= 45), Group II: I-gel (n=45). After preoxygenation, induction and muscle relaxation appropriate size Air-Q or I-gel was inserted and all parameters were noted by an independent observer. Blind tracheal intubation was done through the SAD and hemodynamic parameters were noted. Results: Baseline hemodynamic variables like heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP)] and mean arterial pressure (MAP) was comparable in both the groups. However statistical significant difference was found between two groups in HR, SBP, DBP and MAP after intubation and 1 minute after intubation. Conclusion: We conclude that I-gel causes less haemodynamic stress response to blind tracheal intubation as compared to Air-Q. Keywords: Air-Q, I-gel, Supraglottic airway.
