Input the patient’s weight in pounds in the yellow box and press “enter” on your keyboard.
To calculate the toxic dose of a 1:1 mixture, mark the two corresponding yellow boxes with an “x”
-These calculations assume weight-based toxic doses as defined. Note, these can vary depending on manufacturer and country recommendations.
-These limits are based off recommendations for normal, healthy adults undergoing most routine procedures.
-Toxicity may depend on patient-specific, site-specific and block-specific factors and should be fully assessed on an individual basis.
-For more information on local anesthetic use and recommendations in podiatric surgery, refer to Kihm’s Podiatry Institute Update Article, 2011.
-Maximal total recommended doses: Lidocaine plain 300mg, Lidocaine with Epi 500mg; Marcaine plain 175mg, Marcaine with Epi 225mg.
-When weight-based limits exceed maximum total dose limits, maximum total doses are used.
-Lidocaine and marcaine are believed to have additive toxic effects in humans.
-Use at your own discretion. No liability is assumed for overadministration of local anesthetic.
