Bacterial contamination in cerebrospinal fluid shunt surgery
Scandinavian Journal of Infectious Diseases
|January 1, 1987
Summary
Strict hygienic measures reduced cerebrospinal fluid (CSF) shunt infection rates to 3.1%. However, wound contamination persisted, suggesting improved irrigation systems are needed to prevent infections.
Area of Science:
- Neurosurgery
- Infectious Disease
- Medical Device Safety
Background:
- Cerebrospinal fluid (CSF) shunt infections are a significant complication, occurring in 8-27% of cases.
- Preventing shunt infections is crucial for patient outcomes and reducing healthcare costs.
Purpose of the Study:
- To evaluate the infection rate in patients undergoing CSF shunt surgery with strict hygienic protocols and no prophylactic antibiotics.
- To identify sources of bacterial contamination during the surgical procedure.
Main Methods:
- Prospective study of 64 patients undergoing CSF shunt surgery.
- Implementation of strict preoperative and peroperative hygienic measures.
- Bacterial cultures from the operation area, wound specimens, and irrigation solutions.
Main Results:
- The infection rate was significantly reduced to 3.1% (2 out of 64 patients).
- Bacterial contamination was detected in irrigation solutions (65%) and after skin closure (59%), predominantly by Staphylococcus epidermidis.
- Strict hygiene measures did not fully prevent wound recolonization, indicating potential for endogenous and exogenous spread.
Conclusions:
- Strict hygienic measures can substantially lower CSF shunt infection rates.
- Open irrigation systems are a likely source of bacterial contamination.
- Closed irrigation systems are recommended to further reduce infection risk in CSF shunt surgery.
