Nineteen previously trained resident anaesthetists were instructed to
perform adult single-rescuer basic life support for 5 min on a manikin, in
a double-blind crossover design, changing the hand of contact with the
sternum from right to left while performing external cardiac compression
(ECC). Total, correct and incorrect ECCs comprising of inadequate depth,
wrong hand placement, incomplete relaxation and too much compression were
recorded and grouped according to the dominant hand (group DH) or
non-dominant hand (group NH) in contact with the sternum. The number of
correct ECCs was significantly greater in group DH, median 141 compared to
group NH, median 97; P < 0.005. More ECCs were of inadequate depth in
group NH, median 34 as compared to a median of 8 in group DH; P < 0.005.
Similarly, the incidence of wrong hand placement was significantly higher
in group NH; median of 4 versus median of 0 in group DH, P < 0.05. The
incidence of incomplete relaxation and too much ECC was not significantly
different between the two groups (P < 0.05). We conclude that ECC is
performed with fewer errors when the dominant hand of the rescuer is placed
in contact with the sternum.
