Abstract


Background: In the past decades, a significant increase has been observed in head and face traumas bleeding during and after surgery is one of the most important and dangerous factors for patients. This study was performed to assess the bleeding amount in patients during maxillofacial surgeries and the necessity of blood transfusion.

Methods: In this cross-sectional study, 441 patients were enrolled, of which 83.2% and 16.8% were male and female, respectively. To compare the patients’ mean hemoglobin concentration before and after surgery, paired t-test was used. Furthermore, to compare the mean hemoglobin concentration and mean intraoperative bleeding between males and females, independent t-test was used. The significance level was set as 0.05 for all tests.

Results: Results showed that the mean difference of hemoglobin concentration before and after surgery in patients of the study had a significant difference (P < 0.001). The amount of blood loss during surgery showed no significant difference between males and females (P > 0.050).

Conclusions: The results of this study demonstrated that there was a decrease in mean hemoglobin concentration after surgery, and also, the amount of blood loss in patients during surgery was not high enough for blood transfusion. However, it should be considered that to prevent any problem during surgery, assessing patients with anemia before surgical operations is necessary.
