摘要: Objectives: This study was designed to determine if a) hyperbaric oxygen increases the tissue oxygenation of free flaps and b) verification this effect is possible by using a recently validated innovative method for two-dimensional pO2 measurement (Luminescence lifetime imaging = LLI). Methods: Six patients with parascapular flap transplanted lower limb received (HBOT) therapy. The HBOT regimen consisted treatment over 90 minutes 100% O2 (FiO2 1.0) at 240 kPa (Marx-Schema). transcutaneous partial pressure (ptcO2) measured entire use luminescence (LLI) before 30, 60, 120 after treatment. LLI based on dependent quenching phosphorescence indicator dye platinum (II)-octaethyl-porphyrin implemented in polystyrene sensor foil. Results: In all six we could find significant increase form increased R-values as well subsequently calculated absolute ptcO2 values period min significantly from 42.59 ± 1.11 Torr 81.14 5.95 (p < 0.001). Even 2 hours were higher (83.45 13.80 Torr) compared prior 0.006). Conclusions: findings demonstrated an supply
