Abstract

Context: Preoperative blood bank testing should optimize the trade-off between intraoperative transfusion delay and blood wastage.

Aims: This study aims to develop a maximal surgical blood order schedule (MSBOS) for elective neurosurgery.

Settings and design: Prospective data in University Teaching Hospital, Northern Thailand.

Subjects and methods: Blood transfusion data were collected on all adult patients satisfying inclusion/exclusion criteria in 2015. Patients were assigned to ten procedure groups (G): vascular: (1) Aneurysm/arteriovenous malformation, (2) Cerebrovascular bypass; tumor resection: (3) Meningioma, (4) Other, (5) Cerebellopontine angle, (6) Pituitary/craniopharyngioma, (7) Endoscopic pituitary; and miscellaneous: (8) Cranioplasty, (9) Spine, (10) Other. The crossmatch-transfusion ratio (C/T), transfusion probability (%T), and transfusion index (Ti) were calculated. MSBOS was generated by applying published criteria, subjected to clinical neurosurgical judgment.

Statistical analysis used: Statistical Package for the Social Sciences, Vision 20.

Results: Of 377 patients, 95% underwent preoperative cross-and-match (C and M) testing for 1422 red blood cell (RBC) units, while 3% had no type and screen (T and S) nor C and M, and 2% had T and S only. Overall C/T was 6.6, with range from 4 for G3-53 for G8. Intraoperative %T was 27%. Intraoperative Ti was 0.6. Our MSBOS recommended T and S only for G2, G7, G8, G9, G10; C and M of 2 RBC units for G1, G4, G5, G6; and C and M 2-to-4 for G3. If this were followed in 2015, intraoperative blood needs would have been satisfied for ≥82% of patients, and substantial reductions achieved in blood banking fees.

Conclusions: Our MSBOS may help optimize blood ordering and serve as an example for similar efforts for other surgical specialties.
