Summary

Propionibacterium acnes is a pathogen commonly identified in postoperative shoulder infections. A recent study has shown that P. acnes is likely to be disseminated in the operating field from the subcutaneous layer by the manipulation of soft tissues by the surgeon and the instruments. Disinfection of the subcutaneous tissue seems to significantly reduce contamination of the operating field during primary shoulder surgery. This study seeks to assess the efficacy of disinfection of the subcutaneous tissue compared to dissection with an electrosurgical unit on P. acnes contamination during primary shoulder surgery.

Conditions

  • Surgical Incision

Interventions

PROCEDURE

subcutaneous tissue disinfection

Skin and subcutaneous incision (up to the muscular fascia) with "superficial blade" scalpel, disinfection of the subcutaneous tissue with 3cc of Betadine solution, placement of the retractors, dissection and development of the delto-pectoral interval with "deep blade" scalpel. When the joint is opened, bacteriological smears are taken from 5 sites in the two groups. 1) exposed subcutaneous tissue, 2) surgeon's gloves (distal end of fingers), 3) "superficial blade", 4) "deep blade", 5) retractors. The rest of the shoulder surgery procedure does not differ from what is commonly performed. The samples are sent to bacteriology for bacterial culture. Anaerobic research is done specifically for P. acnes. The results are considered negative after 10 days.
