We compared the preparation times of three solutions commonly used for
epidural top-up for emergency Caesarean section. Twenty-two anaesthetists
were asked to prepare fresh solutions in random order as quickly as
possible: 0.5% bupivacaine 20 ml (B); 2% lidocaine 20 ml with 1:200,000
epinephrine (LE); and 0.5% bupivacaine 10 ml and 2% lidocaine 10 ml with
1:200,000 epinephrine and 8.4% sodium bicarbonate 2 ml (BLEB). Preparation
times for B were approximately half of those for LE, which in turn were
approximately half of those for BLEB (P = 0.0001). If local anaesthetic
solutions with additives such as epinephrine or bicarbonate are prepared
just before emergency Caesarean section, any possible reduction in onset
time that they might afford may be offset by the additional preparation
time required.
