Máscara laríngea I-Gel® versus bolsa-válvula-mascarilla en la reanimación cardiopulmonar instrumental bajo monitorización capnográfica: ensayo clínico piloto aleatorizado por grupos / I-Gel® laryngeal mask versus bag-valve-mask in instrumental cardiopulmonary resuscitation under capnographic monitoring: Cluster-randomized pilot clinical trial

Objetivo: Comparar la vía aérea básica y la vía aérea avanzada con el dispositivo supraglótico I-Gel®, por medio de la capnografía durante la RCP intermedia. Diseño: Estudio piloto experimental aleatorizado por grupos. Emplazamiento: Asistencia extrahospitalaria en unidades de soporte vital básico en la isla de Mallorca. Participantes: Adultos atendidos tras parada cardiorrespiratoria de origen no traumático. Intervenciones: Manejo de la vía aérea avanzado durante la RCP instrumental con I-Gel® o básica con bolsa-válvula-mascarilla, bajo monitorización capnográfica. Mediciones principales: Niveles capnométricos obtenidos según dispositivo empleado, número de inserciones de la I-Gel®, casos sin conseguir una correcta inserción/ventilación por ramas, consecución de ROSC en la RCP y número de ingresos vivos hospitalarios. Resultados: Se reclutaron 23 casos para su análisis. La tasa de éxito de inserción de la I-Gel® fue 92,9% al primer intento, los valores capnométricos medios fueron de 16,3mmHg en grupo control y de 27,4% en el grupo intervención. El 34,8% (n=8) de los pacientes alcanzó recuperación, circulación espontánea en algún momento y el 26,1% (n=6) ingresaron vivos en el hospital. El análisis de supervivencia, atendiendo a la llegada de la unidad y el primer minuto de ventilaciones registrados junto a la variable ingreso vivo hospitalario sugiere una cierta tendencia hacia una mayor supervivencia en la rama intervención (P=0,066). Conclusiones: El uso de la I-Gel® suscita una mejora en la ventilación de los pacientes en PCR, evidenciado por los valores capnométricos medios en el grupo intervención, no encontrándose correlación con variables de resultado de la RCP.(AU)

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 16.3mmHg 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.(AU)
