Drug dosage in isolated limb perfusion: evaluation of a limb volume model for extremity volume calculation
BACKGROUND Exact drug dosing in isolated limb perfusion (ILP) and infusion (ILI) is essential. We developed and evaluated a model for calculating the volume of extremities and compared this model with body weight- and height-dependent parameters. METHODS The extremity was modeled by a row of coupled truncated cones. The sizes of the truncated cone bases were derived from the circumference mea...
متن کاملLimb volume estimates based on limb elliptical vs. circular cross section models.
Limb volumes, as would be estimated by the widely used right circular truncated cone model (right circular frustum), were analytically compared to volume estimates that would be obtained if limbs were represented by an elliptical cross section. A general expression for the ratio of circular to elliptical limb segmental volumes was developed in terms of the ratio of minimum to maximum limb radia...
متن کاملReduction of residual limb volume in people with transtibial amputation.
The early postoperative phase after transtibial amputation is characterized by rapid residual limb volume reduction. Accurate measurement of residual limb volume is important for the timing of fitting a prosthesis. The aim of this study is to analyze the reduction of residual limb volume in people with transtibial amputation and to correlate residual limb volume with residual limb circumference...
متن کاملValidity of estimating limb muscle volume by bioelectrical impedance.
The present study aimed to investigate the validity of estimating muscle volume by bioelectrical impedance analysis. Bioelectrical impedance and series cross-sectional images of the forearm, upper arm, lower leg, and thigh on the right side were determined in 22 healthy young adult men using a specially designed bioelectrical impedance acquisition system and magnetic resonance imaging (MRI) met...
متن کاملAssessment of residual-limb volume change using bioimpedence.
We investigated electrical bioimpedance as a potential measurement modality to assess residual-limb volume change in lower-limb amputees. Four strip electrodes were positioned across the anterior lateral to posterior lateral aspects of the proximal lower leg or residual limb such that the outer pair applied current and the inner pair sensed voltage. A commercial bioimpedance analyzer supplied c...
