BackgroundBleeding is the most common adverse event in patients undergoing cranial vault reconstruction. The authors compare the transfusion rates against a national sample to determine whether the patients experience lower transfusion rates.MethodsThe authors queried the Pediatric National Surgical Quality Improvement Program (Peds-NSQIP) for patients who underwent cranial vault reconstruction (CPT 61559) and compared them to patients who underwent cranial vault reconstruction for sagittal craniosynostosis at Children's Hospital and Medical Center (CHMC) in Omaha, Nebraska. Patients over the age of 24 months were excluded. Binary logistic regression analysis was performed using IBM-SPSS v24.0 to determine factors associated with transfusion at CHMC.ResultsPatient demographics, preoperative hematocrit and platelet counts, readmission rates, and reoperation rates did not differ between CHMC (N = 54) and Peds-NSQIP (N = 1320) cohorts. Patients in the CHMC cohort had shorter preincision anesthesia times (47 versus 80 minutes, P < 0.001), shorter operative times (108 versus 175 minutes, P < 0.001), lower transfusion rates (50% versus 73%, P < 0.001), and smaller mean transfusion volumes (16 versus 33 mL/kg, P < 0.001); however mean length of stay was longer (4.1 versus 3.6 days, P < 0.001). Factors independently associated with transfusion at CHMC included preoperative hematocrit (odds ratio [OR] 0.423, P = 0.002), administration of an antifibrinolytic agent (OR 0.004, P = 0.001) and temperature at the time of incision (OR 0.020, P = 0.043).ConclusionPatients at CHMC require less transfused blood and experience low transfusion rates. Preoperative hematocrit, administration of antifibrinolytic agents, and temperature at the time of incision are all modifiable factors associated with perioperative transfusion.
