Ninety-five patients who underwent posterior lumbar decompression
surgery by a single surgeon were studied retrospectively. Sixteen
patients took omega-3 fatty acid supplements within 14 days of surgery,
stopping an average of 2.3 days before surgery (cases), and the other
patients did not take such supplements within 14 days of surgery
(controls). There was no significant difference between cases and
controls in demographic parameters, use of other anticoagulants, or
surgical time. Mean estimated blood loss was nonsignificantly higher in
cases than in controls (154 vs. 138 ml; p = 0.53). There were two
complications related to bleeding in the control group and none in the
omega-3 fatty acid group. The authors cited five other studies in which
the use of omega-3 fatty acids was not associated with increased risk of
bleeding complications, blood loss, or transfusion requirements in
patients undergoing abdominal surgery or coronary bypass surgery.
Comment: Because fish oil inhibits platelet function, there is concern that it could increase the amount of bleeding during surgery. Most surgeons therefore recommend that fish oil not be taken before surgery. However, the results of this new study and other studies suggest that it is safe to take omega-3 fatty acid supplements, at least up to two days prior to undergoing surgery.
