Abstract:
The incidence of skin contamination of anaesthetic and related staff by patient's blood and saliva was studied during 270 anaesthetics in Cardiff hospitals over seven continuous days in October 1989. A survey was also made of current Hepatitis B immunisation status and glove-wearing habits of 75 anaesthetists. Blood from 35 (14%) patients caused skin contamination of 65 staff during 46 incidents. Twenty-eight (61%) of the contamination incidents occurred during vessel cannulation. Five (8%) of the 65 staff contaminated by blood already had cuts on their hands. There were nine incidents (4%) of skin contamination by saliva. Fifty-three (71%) anaesthetists were immunised against Hepatitis B. Only seven (9%) anaesthetists wear gloves for oral or nasal intubation, six (8%) for insertion of peripheral venous cannulae, 47 (63%) for insertion of arterial lines and 67 (89%) for insertion of central lines. All anaesthetic and associated staff should wear gloves on a routine basis.
Insights
Healthcare staff experienced significant skin contamination from patient blood and saliva during anesthetics. Routine glove use is recommended to prevent exposure and potential infection transmission.
Area of Science:
- Medical safety
- Infection control
- Anesthesiology
Background:
- Healthcare workers face risks of blood and saliva exposure during patient care.
- Hepatitis B immunization and glove use are key preventive measures.
Purpose of the Study:
- To assess the incidence of skin contamination among anesthesia staff.
- To evaluate Hepatitis B immunization rates and glove-wearing practices.
Main Methods:
- Observational study of 270 anesthetics over seven days.
- Survey of 75 anesthetists regarding immunization and glove use.
Main Results:
- 35 patients (14%) caused skin contamination in 65 staff during 46 incidents.
- Vessel cannulation accounted for 61% of blood contamination incidents.
- Nine incidents (4%) of saliva contamination occurred; 8% of staff had pre-existing hand cuts.
Conclusions:
- Anesthesia staff are frequently exposed to blood and saliva.
- Low rates of glove use during certain procedures were observed.
- Routine glove use for all anesthesia staff is strongly recommended.
