In the history of surgery, every single step forward in the development of
complex surgical techniques has been sustained by the acquisition of more r
eliable and effective methods for controlling hemostasis. For many years, i
n fact, uncontrolled hemorrhages, together with infections, represented the
most deadly hazard of surgical procedures. In the last century, technical
advances in surgical hardware and homologous blood transfusions have been u
tilized to counteract operative and postoperative anemia and hypovolemia. A
t the end of this millennium, however, new revelations about the infective
and noninfective risks of allogeneic blood transfusions have led to a new a
cceleration in patients' and physicians' demands for autologous transfusion
s and more efficient blood conservation techniques. Specific surgical proto
cols, based on the preoperative administration of r-HuEPO, preoperative aut
ologous blood donation, acute preoperative normovolemic hemodilution and in
traoperative blood salvage techniques, have been designed by pediatric neur
osurgeons to minimize the exposure of patients affected by craniosynostoses
to allogeneic blood and blood components even when the surgical procedure
is to be realized at an early age. In spite of the evolution expected in th
is area in the immediate future, the implementation of these blood concentr
ation methodologies may prove to be highly effective only when associated w
ith a concerned attitude of the surgeon toward blood-sparing intraoperative
strategies.
