One-rescuer newborn CPR using a face mask or an i-gel supraglottic airway and two-finger compressions – A manikin study with cross-over desgin

INTRODUCTION: When unanticipated neonatal asphyxia occurs, it may be necessary for a single resuscitator to commence advanced resuscitation before others arrive. We hypothesised that a single rescuer can provide positive pressure ventilations and chest compressions using higher inflation pressures and better adherence to the recommended compression rate with an i-gel supraglottic airway than with a face mask. METHOD: A manikin-based cross-over study was conducted. Twenty-one midwives performed both positive pressure ventilation using a T-piece and chest compressions with the two-finger technique on a newborn manikin alone. They performed ventilation with a face mask or an i-gel. The peak inspiratory pressure (PIP) was set to 30 cmH(2)O. The actual PIPs were evaluated based on the values displayed on the manometer. The total amount of time taken to complete 30 cycles of three compressions and one ventilation was also evaluated. RESULTS: The mean of the average PIP for each participant was significantly lower with a face mask than with an i-gel (17.3 ± 4.4 vs 28.2 ± 2.0 cmH(2)O, p < 0.00001). The amount of time taken to complete 30 cycles was significantly longer with a face mask than with an i-gel (66.2 ± 6.1 vs 60.6 ± 3.4 seconds, p < 0.0001). CONCLUSION: During one-rescuer newborn resuscitation using a T-piece and the two-finger technique, the PIPs are consistently high and 30 cycles of CPR are better adhered to 60 seconds using an i-gel.
