[Wash and non-wash system in the perioperative recovery of blood in prosthetic surgery: ultrastructural assessment of corpuscular blood components]. / Sistema wash e non-wash nel recupero perioperatorio del sangue in chirurgia protesica: valutazione ultrastrutturale della parte corpuscolata del sangue.

AIM: 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. EXPERIMENTAL PROTOCOL: 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. MATERIALS AND 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. DISCUSSION AND 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.
