Prevalence and Associated Factors of Blood Transfusion in Spinal Surgery at Maharat Nakhonratchasima Hospital: A Retrospective Study
Keywords:
associated factors, blood transfusion, prevalence, spine surgeryAbstract
Background: Spine surgery is a high rate of blood
transfusion. This is costly and may have many adverse
effects. Previous studies showed multiple factors
associated with blood transfusion but in our institute, there
is no exact data. Our study is designed to identify
prevalence and associated factors of blood transfusion.
Methods: A retrospective study was designed to identify
all patients undergone spine surgery between 1st February
2019 to 31st January 2020. Demographic data including
amount of blood component given, age, gender, ASA
physical status, BMI, underlying disease, preoperative
hemoglobin, diagnosis and the details of surgery, operative
time and intraoperative blood loss were collected.
Primary outcome was a prevalence of blood transfusion
and secondary outcome was the associated factors of
this transfusion.
Results: Five hundred and sixty-five patients were
included. One hundred and three patients required packed red cell (PRC) transfusion and sixteen patients
required fresh frozen plasma (FFP). Mean PRC and FFP
transfusion are 447.63 and 442.81 ml. One patient needs
10 units of platelet transfusion. Factors associated with
blood transfusion were pulmonary disease (p-value=0.01,
OR=3.60), low preoperative hemoglobin (10-13 g/dl;
p-value <0.001, OR=4.51, < 10 g/dl; p-value=0.01,
OR=8.06), > 3 levels of surgical segments (p-value=0.001,
OR=3.75), posterior approach (p-value=0.01, OR=5.13)
and operative time >120 minutes (p-value<0.001,
OR=19.26).
Conclusions: Prevalence of blood transfusion is 22%
that is considered high and the need for transfusion is
associated with multiple factors. Health care providers
should be aware and well-prepared these cases vigilantly
in order to optimize patient management.
