Abstract
Introduction
Good quality basic life support (BLS) is associated with improved outcome from cardiac
arrest. Chest compression fraction (CCF) is a BLS quality indicator, which may be
influenced by the type of airway used. We aimed to assess CCF according to the airway
strategy in the PARAMEDIC2 study: no advanced airway, supraglottic airway (SGA), tracheal
intubation, or a combination of the two. Our hypothesis was that tracheal intubation
was associated with a decrease in the CCF compared with alternative airway management
strategies.
Methods
PARAMEDIC2 was a multicentre double-blinded placebo-controlled trial of adrenaline
vs placebo in out-of-hospital cardiac arrest. Data showing compression rate and ratio
from patients recruited by London Ambulance Service (LAS) as part of this study was
collated and analysed according to the advanced airway used during the resuscitation
attempt.
Results
CPR process data were available from 286/ 2058 (13.9%) of the total patients recruited
by LAS. The mean compression rate for the first 5 min of data recording was the same
in all groups (P = 0.272) and ranged from 104.2 (95% CI of mean: 100.5, 107.8) min−1 to 108.0 (95% CI of mean: 105.1, 108.3) min−1. The mean compression fraction was also similar across all groups (P = 0.159) and
ranged between 74.7% and 78.4%. There was no difference in the compression rates and
fractions across the airway management groups, regardless of the duration of CPR.
Conclusion
There was no significant difference in the compression fraction associated with the
airway management strategy.
