About this study
Official title: Comparative Evaluation of One-handed E-C Clamp Mask Holding Technique, Two-handed Mask Ventilation With Jaw Thrust, and Two-handed Mask Ventilation With Triple Airway Maneuver in the Unconscious Apneic Person
One-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver are three common airway management maneuvers. Sniffing position may improve ventilation between these three maneuvers. The investigators hypothesize that ventilation efficiency may be different between these three maneuvers whether the patient is in sniffing position or neutral position. The investigators would like to quantify this effect by measuring the expired tidal volume, airway pressure, EtCO2 slope and hemodynamic change between these three maneuvers during anesthesia induction.
Read the detailed description
Mask ventilation is considered a important skill for airway management during general anesthesia induction and for apneic unconscious patients. One-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver are three common airway management maneuvers. However, the efficiency of ventilation between these three maneuvers has to be clarified. Besides, whether sniffing position or neutral position may improve ventilation between these three maneuvers is to be determined. The investigators will collect airway parameters of the patients receiving general anesthesia and measure the expired tidal volume, airway pressure, EtCO2 slope and hemodynamic change between these three maneuvers during anesthesia induction.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
airway maneuverProcedure or surgery
Three-period crossover study: During general anesthesia induction, subjects are assigned to one of the 6 airway maneuver sequences (ABC, CAB, BCA, ACB, CBA, or BAC) in accordance with a randomization schedule. Each maneuver is performed 5 times in a period.
Airway maneuver A: E-C clamp mask holding technique; Airway maneuver B: two-handed mask ventilation with jaw thrust airway maneuver; Airway maneuver C: two-handed mask ventilation with triple airway maneuver(combine jaw thrust and head tilt chin lift)
| Study group | Role | What they receive |
|---|---|---|
| E-C clamp mask holding technique | Experimental | the airway maneuver that press the mask against the patient's face (using the "C" of our thumb and forefinger) while pulling the jaw forward (using the "E" of our other fingers behind the mandible), and leaves one hand free to squeeze the bag. Receives: Procedure: airway maneuver |
| two-handed ventilation with jaw thrust | Experimental | the airway maneuver performed with thumbs point toward feet, palms press down and other fingers perform jaw thrust Receives: Procedure: airway maneuver |
| triple airway maneuver | Experimental | the airway maneuver performed with two-handed mask ventilation, jaw thrust and head-tilt chin-lift technique Receives: Procedure: airway maneuver |
What is being measured
The primary outcome is the main question the study is designed to answer.
Air exchange
Expired tidal volume, end tidal CO2 slope, peak inspiratory pressure between one-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver
Measured: during anesthesia induction
Secondary outcomes (1)
Hemodynamic change
blood pressure and heart rate variability during ventilation between one-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver
Measured: during anesthesia induction

Sniffing position may improve ventilation between these three maneuvers.
