[Bacterial environment and infectious complications of arterial prostheses. Retrospective study of 111 cases]
Abstract:
648 pre-, per-, or post-operative bacteriological sample or 111 arterial prosthesis operated in a general surgical word were reviewed. Per operative cultures were positive in 2,5 per cent (intra-arterial thrombus or aneurysm wall), systematic post-operative cultures in 2,7 per cent (IV and urinary catheters, drains) and clinically oriented post-operative cultures in 10 per cent. No correlation between open pre-operative infection or bacterial contamination far from the wound and prosthetic infection was noted. Never the less, positive per-operative cultures or drains cultures has to be considered as a potential sepsis. According to the prevention of infection in a word including septic patients, the rate of prosthetic contamination was 1,8 per-cent and the rate of sub-cutaneous wound infection was 3,6 per-cent, which does not seem to be greater than usual results.
Insights
Bacteriological samples from 648 surgeries and 111 arterial prostheses were reviewed. Positive intra-operative cultures and drain cultures may indicate sepsis, but prosthetic contamination rates remained low.
Area of Science:
- Surgical infection control
- Bacteriology
- Prosthetic device infections
Context:
- Review of 648 surgical bacteriological samples and 111 arterial prostheses.
- Analysis of pre-, peri-, and post-operative culture results.
- Assessment of infection rates in a general surgical ward, including septic patients.
Purpose:
- To evaluate the significance of bacteriological cultures in surgical patients.
- To determine the correlation between pre-operative infection and prosthetic infection.
- To assess prosthetic contamination and wound infection rates in a general surgical setting.
Summary:
- Peri-operative cultures were positive in 2.5% (intra-arterial thrombus/aneurysm wall).
- Systematic post-operative cultures (catheters, drains) were positive in 2.7%.
- Clinically oriented post-operative cultures showed a 10% positivity rate.
- No correlation found between distant pre-operative infection and prosthetic infection.
- Positive peri-operative or drain cultures suggest potential sepsis.
- Prosthetic contamination rate was 1.8%, and subcutaneous wound infection rate was 3.6%.
Impact:
- Highlights the importance of peri-operative and drain cultures for sepsis detection.
- Suggests that current infection prevention strategies are effective in reducing prosthetic contamination.
- Provides benchmark data for surgical site infection rates in a general surgical ward.
