Introduction. 9, 15 In obese patients, the adjusted body weight provides another alternative, 25, 26 which may be beneficial: Actual Body Weight is the weight measured during hospitalization or reported just before the hospitalization; ideal body weight is the weight related to the height; adjusted body weight is applicable in the obese patient and is calculated as (actual body weight ideal body weight) 0.33 + ideal body weight. When we consider the above terms, we calculate the adjusted body weight by adding the difference ABW and IBW multiplied by 0.4 to the ideal body weight. Then hit Enter, and the appropriate dosage amount and number of single vials will populate. Data will be collected and analyzed on an intent-to-treat basis. Remember to discard any unused solution remaining in the vials. 4.0 For MRSA and MSSA bacteremia, endocarditis, 6 mg/kg, based on IBW, for 2-6 weeks.
