Abstract:
Blood splash contamination of the conjunctivae or buccal mucosa may occur during angiography and angioplasty. Since there is a risk of contracting Hepatitis B or HIV via this route, staff should be aware of this potential source of infection. The use of protective masks and goggles or glasses should be considered. We have studied the risk of contamination by asking both the radiologist and angiography nurse to wear spectacles and disposable masks during 100 consecutive angiographic procedures. The number of splashes was counted at the end of each procedure. Blood splashes occurred in seven procedures and there was a total of 23 splashes during the study. In conclusion, we believe that there is a significant risk of conjunctival or mucosal contamination with blood during angiographic procedures and given the potential seriousness of transmission of Hepatitis B or HIV, radiologists and nursing staff must be aware of this risk.
Insights
Healthcare staff face a risk of blood splash contamination during angiography and angioplasty. Protective eyewear and masks are recommended to prevent potential Hepatitis B or HIV transmission.
Area of Science:
- Medical Procedures
- Infectious Disease Transmission
- Occupational Safety
Background:
- Blood splash contamination of mucous membranes can occur during angiography and angioplasty.
- There is a risk of transmitting Hepatitis B (HBV) or Human Immunodeficiency Virus (HIV) through such exposures.
Purpose of the Study:
- To assess the risk of blood splash contamination to the conjunctivae and buccal mucosa during angiographic procedures.
- To evaluate the effectiveness of protective measures like masks and eyewear.
Main Methods:
- A prospective study involving 100 consecutive angiographic procedures.
- Radiologists and nurses wore spectacles and disposable masks during procedures.
- The number of blood splashes was recorded after each procedure.
Main Results:
- Blood splashes occurred in 7 out of 100 procedures.
- A total of 23 blood splashes were documented during the study period.
- This indicates a notable frequency of exposure events.
Conclusions:
- There is a significant risk of conjunctival or mucosal contamination with blood during angiographic procedures.
- Radiologists and nursing staff must be aware of this occupational hazard.
- Consistent use of protective equipment is crucial to mitigate infection risks.
