Máscara laríngea I-Gel® versus bolsa-válvula-mascarilla en la reanimación cardiopulmonar instrumental bajo monitorización capnográfica: ensayo clínico piloto aleatorizado por grupos

OBJECTIVE: To compare the basic airway and the advanced airway with the supraglottic device I-Gel®, by means of capnography during intermediate CPR. DESIGN: Randomized experimental pilot study by groups. SETTING: Out-hospital care basic life support units on the Island of Mallorca. PARTICIPANTS: Adults attended after cardiorespiratory arrest of non-traumatic origin. INTERVENTIONS: Advanced airway management during instrumental CPR with I-Gel® or basic CPR with bag-valve-mask, under capnographic monitoring. MAIN MEASUREMENTS: Capnometric levels obtained according to the device used, number of insertions of the I-Gel®, cases without achieving correct insertion/ventilation by branches, achievement of ROSC in CPR and number of hospital live admissions. RESULTS: Twenty-three cases were recruited for analysis. The insertion success rate of the I-Gel® was 92.9% at the first attempt, the mean capnometric values were 16.3 mmHg in the control group and 27.4% in the intervention group. 34.8% (n = 8) of the patients achieved spontaneous circulation recovery at some point and 26.1% (n = 6) were admitted to hospital alive. The survival analysis, taking into account the arrival of the unit and the first minute of ventilations recorded together with the variable hospital admission, suggests a certain trend of greater survival in the intervention branch (P = .066). CONCLUSIONS: The use of I-Gel® raises an improvement in the ventilation of the patients in PCR, evidenced by the mean capnometric values in the intervention group, finding no correlation with CPR outcome variables.
