Abstract

Introduction:We study the hematological and microbiological characteristics from the autologous

blood processed through the intraoperative cell saver used in our centre (Orthopat®) during the

correction of pediatric scoliosis, which is known to be a potentially bleeding surgery.

Material and methods: Descriptive analysis of 31 patients undergoing pediatric scoliosis surgery. All

of them received blood processed by cell saver intraoperatively. The variables collected were:

demographic data, volume of the autogenous red blood cell (RBC) concentrate, blood count,

biochemistry, blood culture, preoperative and postoperative blood tests of the patients, incidence

of fever during reinfusion of RBC concentrate, postoperative surgical site infections and length of

hospital stay.

Results: Average volume obtained 288.06ml (sd 154.68). Hematocrit 70.38% (sd 10.03) in

accordance with cell-saver commercial data (75%). Of the blood samples obtained, 42.86%  had

blood cultures that were positive for aerobes and 48.28% for anaerobes. The relation between

postoperative infections and contamination of blood concentrates was not statistically significant.

When comparing the pre-surgery and post-surgery analytical samples, statistically significant

differences (p <0.05) were found in the following: hemoglobin and hematocrit decreased in the

postoperative period, while coagulation parameters show a tendency to coagulopathy.

Conclusion: Our cell saver obtains RBC concentrates with a percentage of hematocrit in agreement

with available information. The reinfusion of them is safe from an infectious and biochemical point

of view, but its immunological implications are not clear. This surgery continues to result in a

significant loss of blood. Measures taken to avoid allogenic transfusions remain necessary and

should be enhanced.
