Does low-dose oral vitamin K reliably reverse over-anticoagulation due to warfarin?
In patients receiving warfarin who have asymptomatic excessive prolongations in their INR results, 1 mg of oral vitamin K reliably reduces the INR to the therapeutic range within 24 h. This therapy is more convenient, less expensive, and might be safer than parenteral vitamin K. Thus, it should be considered in all non-bleeding patients receiving warfarin, who present with INR results of 4.5 to 9.5.
In a case-matched setting with a small sample size, single-port laparoscopic colectomy has comparable outcomes to conventional laparoscopic colectomy.
