A neonate underwent resection of an extensive sacrococcygeal teratoma
after receiving a bolus of 40,000 Kallikrein Inhibitory Units of aprot
inin at induction of anaesthesia. The measured blood loss was 30 ml, l
ess than 10% of blood volume, and was replaced with an intravenous col
loid solution, avoiding blood transfusion. The blood loss was low comp
ared to previous resections of similar sacrococcygeal teratomas (mean
118 ml, range 60-250 ml) and suggests that aprotinin may be beneficial
in blood conservation during extensive dissections in infants.
