Quantitation of local acidosis and hypoxia produced by infection

Increased strength of healing incisions infected with E coli was demonstrated in this experiment. Efforts to measure respiratory gas tensions and pH in these incisions were unsuccessful. Therefore, these moieties were measured in normal and infected wound fluid contained in implanted wire cylinders. The wound fluid from infected cylinders was consistently more acidotic and had a lower pO2 and a higher pCO2 than fluid from unifected wound cylinders.
