(HealthDay News) – Patients who discontinue aspirin use seven days or more before lumbar fusion surgery have no differences in histological outcomes compared with those who do not use aspirin, according to a study published in the Aug. 15 issue of Spine.
Jin Hoon Park, MD, PhD, from Gangneung Asan Hospital in South Korea, and colleagues assessed 182 cases of one- or two-level lumbar fusion surgery performed by a single surgeon; 96 patients did not use aspirin before surgery. The 86 aspirin users were classified according to the number of days prior to surgery that they discontinued their aspirin use, with aspirin 1 group and aspirin 2 group discontinuing aspirin use 3–7 and 7–10 days before surgery, respectively.
The researchers found that for one-level fusion surgery the total amount of drained blood and the duration of indwelling of the drainage catheter were significantly less in the control group than in the aspirin 1 group. However, these outcomes were not significantly different for the aspirin 2 group and control group for one-level fusion surgery. For patients undergoing two-level fusion surgery, the control group had significantly less catheter drainage than the aspirin 1 group.
“If aspirin was discontinued seven days or longer before surgery, there was no difference in the study parameters, compared with the control group,” the authors write.
