Polyglycolic acid (Dexon) sutures in Escherichia coli infected urine.

The tensile strength, knot strength and stretch of polyglycolic acid (Dexon) was studied after emersion in physiological saline, sterile urine and infected urine. Tests were made each day under controlled conditions over a 10 day period. The results are compared with those of other earlier studies. Tensile strength, knot strength and stretch were found to be fully acceptable in all studies, and there are no grounds to advise against the use of Dexon when urine is infected.
