Riesgo de transfusión perioperatoria en la cirugía del fémur

The purpose is to analyse the likelihood of perioperative transfusion in femur surgery ping the data of the abstracted patient discharge records. Patients with femur surgical procedures patient performed during 1996 in the Central Hospital of Asturas were studied. The abstracted patient discharge records were codified according to the ICD-0 CM codes. Gender, age, diagnosis, procedures, among them the transfusions of blood derivates and the surgical procedures were analysed. Out of 256 operated patients, 64 (25%) were transfused. The groups of patients more frequently transfused were those more older than 70 years (29.5), femur fracture (27.7%) and patients undergoing three o more surgical techniques during the surgical intervention (50%). By multivariate logistic regression analysis, the age and the number of surgical techniques where factors independently related with the likelihood of being transfused. The adjusted odds ratio of perioperative transfusion in patients than 70 year in 2.49 times in relation with the rest of people (p:0.01), and in patients who undergoing three or more surgical techniques 4.03 times in relation to those with 1 or 2 surgeries (p:0.015). Among the variables studied, age and the number surgical techniques (as an indirect surgical complexity index) are factors independently related with the likelihood of being transfused.
