Journal Title: Sultan Qaboos University Medical Journal - Year 2009, Vol 9, Issue 3
Abstract
Minor oral surgery (MOS) procedures in warfarinised patients carry the risk of post-operative bleeding. Te aim of this study was to conduct a retrospective analysis and to describe the profle of warfarinised patients who underwent MOS procedures at Sultan Qaboos University Hospital. Methods: A retrospective study of 124 warfarinised patients (41 men and 83 women), who had a pre-operative international normalised ratio (INR) of ≤ 3.5 and underwent different MOS procedures under local anaesthesia, without discontinuation of their warfarin therapy, was carried out over a 5-year period from January 2004 to December 2008. Results: Ninety (72.6%) patients had simple dental extractions, 26 (21%) surgical extractions, 6 (4.8%) soft tissue biopsies and 2 (1.6%) had apicectomies with cyst enucleations. Local measures were applied in all patients, which included the use of oxidizing regenerated cellulose haemostatic agent (Surgicel) and suturing. A total of eight patients (6.5%), fve who had surgical extractions and three who had simple extractions, bled enough post-operatively to require a return to hospital. All cases of post-operative bleeding were managed conservatively by repacking the bleeding site with haemostatic agent and re-suturing without the need for hospital admission. Conclusion: Minor oral surgery procedures can be safely conducted in warfarinised patients without interruption of warfarin regimen when the pre-operative INR is ≤ 3.5 and appropriate local haemostatic measures are used.
