How do you calculate BKA?
How do you calculate BKA?
The following estimates are reasonable for determining a patient’s amputation ideal body weight (or adjusted body weight for overweight patients)….Estimated Body Weight Loss (EBWL) Table.
| Level of Amputation | % EBWL |
|---|---|
| Below-knee amputation (BKA) | 3.5% |
| Above-knee amputation (AKA) | 11% |
| Hip disarticulation | 16% |
| Hand | 0.7% |
How does amputation affect creatinine clearance?
Patients undergoing amputation are at particularly high risk of incorrect estimation of kidney function based on creatinine, due to malnutrition and loss of muscle mass [15,16,18,19], which may lead to inappropriate prescribing of renally-eliminated medications.
How do you calculate BKA BMI?
How is BMI calculated?
- Step 1 – Calculate estimated body weight. We= W0/(1-P)
- Step 2 – Calculate estimated BMI. Estimated BMI = [estimated body weight (lb)/height (in)2] x 703. Estimated BMI = [We(lb)/height(in)2] x 703. For P, we used the following estimates for percentage of total body mass for common amputation levels.
What is the difference between IBW and ABW?
ABW = IBW + 0.4 (actual weight – IBW) The IBW and ABW are used to calculate medication dosages when the patient is obese. This formula only applies to persons 60 inches (152 cm) or taller.
Which is more accurate GFR or creatinine clearance?
Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR .
Is GFR equal to creatinine clearance?
Creatinine Clearance ( CrCl ) versus Glomerular Filtration Rate ( GFR ) Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).
What is seated height?
Sitting height gives a measure of the length of the trunk. It is a measurement of the distance from the highest point on the head to the base sitting surface. Distance can be measured from the floor, and the height of the box measured and subtracted from the total distance.
What is rehabilitation of lower limb amputation (2017)?
Rehabilitation of Lower Limb Amputation (2017) The guideline describes the critical decision points in the Rehabilitation of Lower Limb Amputation and provides clear and comprehensive evidence based recommendations incorporating current information and practices for practitioners throughout the DoD and VA Health Care systems.
How does the calculator determine the non-amputated weight?
The calculator will determine the non-amputated weight based on the amputated weight and the extend of the amputations. The percentage of body mass is used as follows: Foot 1.35%, at the knee 6.2%, at the hip 18%, hand 0.6%, at elbow 2.25%, at shoulder 5%.
What are the guidelines for aminoglycoside dosing for adults?
Aminoglycoside Dosing Guidelines for Adults. Necessary Patient Information for Dosing. Ideal body weight (IBW) o Use of IBW is recommended for aminoglycoside dosing unless patient meets criteria for. utilization of ABW or AdBW (below) Males = 50 + 2.3 x [height (in) – 60] Females = 45.5 + 2.3 x [height (in) – 60] Actual body weight (ABW)
How is the dosing of cytotoxic chemotherapy based on BSA determined?
The dosing of cytotoxic chemotherapy is often based on a measurement of body surface area (BSA). Although the use of BSA has been shown to be a poor estimate of drug metabolism, because it does not account for interpatient variability in complex biologic processes such as enzymatic activity, it remains a standard when prescribing chemotherapy.
