Subsequent INR readings are influenced by the dose, method, and initial INR of vitamin K. For intravenous vitamin K doses of 2 mg or more, INR decrease is comparable. FFP preadministration has no effect on INR readings 48 hours or more after vitamin K administration.
What is Abstract of Vitamin K dosing to reverse warfarin based on INR, route of administration, and home warfarin dose in the acute/critical care setting?
Commonly, vitamin K is used to reverse the anticoagulant effects of warfarin. The ideal vitamin K dosage and delivery method that does not lengthen bridging therapy are still unclear.
To ascertain the elements affecting the level and pace of vitamin K-induced INR reversal in the acute/critical care setting.
400 patients' charts from between February 2008 and November 2010 who got vitamin K to counteract the effects of warfarin were examined. International normalized ratios (INRs), intravenous or oral vitamin K doses, and whether or not fresh frozen plasma (FFP) was administered were among the information gathered. INRs were measured 12, 24, and 48 hours before vitamin K treatment.
At baseline, 12 hours, 24 hours, and 48 hours, respectively, intravenous vitamin K decreased INR more quickly than oral vitamin K (5.09, 1.91, 1.54, and 1.41 vs. 5.67, 2.90, 2.14, and 1.58). Subsequent INR values were impacted by baseline INR (p 0.001), method of administration (p 0.001), and vitamin K dosage (p 0.001). For intravenous vitamin K doses of 2 mg or more, there was a similar drop in INR. Home warfarin dose had no effect on INR responses to intravenous or oral vitamin K (p = 0.98 and 0.27, respectively). FFP had no effect on INR readings 48 hours later. Although larger vitamin K doses and longer anticoagulation bridge therapy appeared to be related, neither the incidence (p = 0.63) nor the duration (p = 0.61) were statistically significant.
His leg felt like giving out when attempting to walk. He explains that he twisted his knee while trying to change direction. He heard a loud pop as his knee gave in.
Market failure occurs when there is a state of disequilibrium in the market due to market distortion. It takes place when the quantity of goods or services supplied is not equal to the quantity of goods or services demanded. Some of the distortions that may affect the free market may include monopoly power.
