Clinical Experience of Autologous Blood Transfusion in Neurosurgery: Prospective Study in Central India.

OBJECTIVE: To evaluate the benefits of intraoperative autologous blood transfusion in intracranial procedures and to conserve precious homologous blood due to shortage of donor and associated complications.

METHODS: This was a prospective study performed at Bansal Hospital, Bhopal. Predetermined autologous blood was collected in a well-labeled bag containing citrate phosphate dextrose adenine solution after induction of general anesthesia. Then appropriate amount of crystalloid solution was transfused in to the body. All collected autologous blood was transfused back to the patient at the end of the surgery or during the surgery if excessive blood loss occurred. Demographic data, hemodynamic changes (mean arterial pressure, heart rate) before and after donation, complications, and any additional homologous blood requirement were noted. Pre- and postoperative hemoglobin and hematocrit values were compared.

RESULTS: In total, 32 patients were included in this study. In our study, mean age was 48.87 years; male-to-female ratio was 1:1.4. The mean amount of autologous blood collected was 461 mL, and the mean amount of blood loss during surgery was 1048 mL. In our study, there was no statistically significant difference was found in mean arterial pressure and heart rate before and after autologous blood collection (P > 0.05). When we compared pre- and postoperative mean hemoglobin and hematocrit levels, there was a statistically significant difference present (P < 0.05); this was due to the fact that many patients had meningiomas (15 of 32). Additional homologous blood was required only in 25% of cases (8/32). Of 8 patients, 5 were again cases of deep-seated meningiomas. No complications were observed during or after autologous blood collection.

CONCLUSIONS: Autologous blood transfusion is a safe, effective, and affordable method of blood transfusion in patients undergoing intracranial surgery. Complications associated with homologous blood transfusion can be avoided with autologous blood transfusion.
