Key result
Insertion of the Brain laryngeal mask airway caused significant increases in arterial pressure (p<0.02) and heart rate (p<0.001), with no difference compared to the Guedel oral airway.
Why the study?
Does the insertion of a Brain laryngeal mask airway cause different cardiovascular responses compared to a Guedel oral airway in patients undergoing anesthesia?
Population
100 patients undergoing induction of anaesthesia with 2.5 mg/kg of propofol
Comparison
Insertion of Brain laryngeal mask airway vs Insertion of Guedel oral airway
Follow-up
60 seconds post-insertion

Significant BP drop and HR rise after propofol may warrant monitoring during airway insertion; leaves open LMA vs oral airway effects.
Does the insertion of a Brain laryngeal mask airway cause different cardiovascular responses compared to a Guedel oral airway in patients undergoing anesthesia?
Insertion of a Brain laryngeal mask airway elicits a similar transient cardiovascular stress response (increased blood pressure and heart rate) as a Guedel oral airway.
Hickey et al. (1990) studied Patients undergoing anaesthesia (n=100). Brain laryngeal mask airway vs. Guedel oral airway was evaluated on Changes in arterial pressure and heart rate. Insertion of the Brain laryngeal mask airway caused significant increases in arterial pressure (p<0.02) and heart rate (p<0.001), with no difference compared to the Guedel oral airway.
