RESPONSES OF SKELETAL MUSCLE pH TO INJURY: A NEW TECHNIQUE FOR DETERMINATION OF TISSUE VIABILITY
Abstract
Conventional criteria for estimation of viability of skeletal muscle include direct observation of color, consistency, contractility, bleeding, and the use of various staining methods. The latter techniques have definite limitations which render them impractical or imprecise for clinical application. The present study was designed to evaluate the technique of electrometric surface pH measurement in assessment of skeletal muscle viability following crush, thermal, and high velocity missile injury. Surface electrometric pH of skeletal muscle demonstrates significant changes after crush, thermal, and high velocity missile injury. The anatomic correlation of these changes with the distribution of vital dye indicates that surface hydrogen ion activity of skeletal muscle is readily altered by changes in tissue perfusion. Further studies will be directed toward definition of the extent of pH change which is consistently associated with tissue death.
