Abstract
STUDY DESIGN
Retrospective cohort study using prospectively collected data.
OBJECTIVE
To determine the effectiveness of intraoperative tranexamic acid (TXA) in anterior cervical discectomy and fusion (ACDF) on postoperative blood loss.
SUMMARY OF BACKGROUND DATA
TXA has been proven to be a safe and effective agent in reducing blood loss after cervical surgery; however, its efficacy when used intraoperatively for ACDF surgeries had yet to be researched. Currently, there are few studies examining the effects of intraoperative TXA in cervical spinal fusion, and none specifically examining TXA use in ACDF.
METHODS
A tertiary medical center's prospectively collected spine registry was queried between 1/1/18 and 12/1/21 for all patients who underwent elective ACDF surgery and received a drain postoperatively. Patients were separated into 2 groups; those who had received intraoperative TXA and those who did not. Baseline demographic and operative variables were collected from the registry. The primary outcome was postoperative blood loss over a 24-hour period. Secondary outcomes included total drain output, intraoperative estimated blood loss, operative duration, drain duration, changes in preoperative to postoperative hemoglobin and hematocrit levels, and rate of transfusions, complications, revisions, and reoperations. Univariate and multivariate regression analyses were performed.
RESULTS
Two hundred eighty-six patients were included. One hundred ninety patients underwent ACDF and did not receive intraoperative TXA, whereas 96 patients underwent ACDF and did receive TXA. There were no differences in any demographic or baseline variables. Multivariate analysis showed intraoperative TXA was associated with shorter drain duration (β=-5.74, 95% CI: -10.9 to -0.53, P =0.031) and reduction in 24-hour drain output (β=-12.2, 95% CI: -19.4 to -4.89, P =0.001) and total drain output (β=-14.0, 95% CI: -22.9 to -5.05, P =0.002).
CONCLUSIONS
TXA use during ACDF procedures leads to a decrease in perioperative blood loss and faster drain removal. TXA is an effective and safe agent for reducing perioperative blood loss in ACDF surgery.
