[Wash and non-wash system in the perioperative recovery of blood in prosthetic surgery: ultrastructural assessment of corpuscular blood components].
OBJECTIVE
The authors aimed to perform an ultrastructural morphological analysis of blood recovered using wash and non-wash systems in patients undergoing full cement-free hip replacement in order to evaluate the integrity of the various blood corpuscle components.


METHODS
An open prospective study in patients undergoing full cement-free hip replacement at the Orthopedics Division of S. Orsola-Malpighi Policlinico in Bologna. Materials of S. Orsola-Malpighi Policlinico in Bologna.


METHODS
Blood recovered postoperatively using a non-wash system was studied in 6 patients. In a further 3 patients perioperatively recovered blood was studied after washing using Cell Saver Haemolite 2 before reinfusion. Red globules, white globules and plaelets were isolated from blood collected using these two different recovery systems and analysed by SEM.


RESULTS
Study of the ultrastructural morphology of various corpusculated blood fractions.


CONCLUSIONS
From the data in our possession it appears that the ultrastructural morphology of the various corpuscle components of blood in subjects undergoing postoperative recovery is better preserved using a non-wash system. There was no sign of "polluting" material in terms of adipose cells or free bone fragments in either group.
