perfusion index
Numerical measurement used to quantify regional tissue perfusion during isolated organ perfusion procedures in oncologic surgery.
Full Definition
The perfusion index is a quantitative parameter used to assess the adequacy and distribution of perfusion during isolated limb perfusion or isolated hepatic perfusion procedures in oncologic surgery. This measurement helps surgeons monitor the effectiveness of chemotherapy delivery to target tissues while ensuring adequate circulation. The index is calculated based on flow rates, pressures, and sometimes temperature measurements during the perfusion procedure. Maintaining optimal perfusion parameters is crucial for maximizing therapeutic efficacy while minimizing systemic toxicity. The perfusion index serves as both a real-time monitoring tool and a quality assurance measure for these specialized oncologic procedures.
Usage
Usage note: Often expressed as a numerical value or percentage in procedural documentation.
In Context
- "The perfusion index remained stable throughout the isolated limb perfusion procedure." — Intraoperative monitoring report
- "Suboptimal perfusion index values prompted adjustment of flow parameters." — Procedural note
