THE AIDS AUTOPSY

The CDC has recommended protective masks and eyewear (or face shields), laboratory
gowns, gloves, and waterproof aprons be worn when performing or attending all autopsies.[160]
All autopsy material should be considered potentially infectious for both HIV and HBV.
Onlookers with an opportunity for exposure to blood or fluid splashes should be similarly
protected. Routine standard infection control practices should be employed for all cases. Use a
detergent to clean bloody or soiled work surfaces, followed by 0.5% sodium hypochlorite as a
disinfectant in ALL areas of the autopsy department, except on sensitive equipment, where
alternative disinfectants are used (Table 9).[1092]
The best defense against accidents is good technique. Though many dissection skills in
autopsy are similar to surgical pathology, some are unique and require specific training, such as
evisceration of abdominal and thoracic organs or brain and spinal cord removal. A protective
face shield is recommended with use of an oscillating saw, as with any power tool. Also
available for use are hand protectors such as steel mesh gloves or "fishing" gloves of tough
fabric, which may provide additional security with evisceration of organs.
Although disposable latex or vinyl gloves are quite reliable, leakage can occur, so double
gloving is recommended.[1093] If cuts or abrasions on potentially exposed skin surfaces are
present, they should be taped or covered before protective gear is put on. Persons performing
frozen sections on HIV contaminated tissues using a cryostat designated for this purpose must be
protected similarly to when handling fresh tissue.
Fixed tissues or fluids may be disposed of in a routine fashion through a tissue grinder to
sanitary sewer or through incineration. Fresh tissues, blood, and body fluids can be autoclaved
or placed in fixatives prior to disposal in accordance with local statutes. Formalin is the most
cost-effective and efficacious fixative. Other contaminated wastes can be collected into marked,
leak proof plastic bags and incinerated. Housekeeping personnel handling this material should
use protective gear. Needles should never be recapped, and all needles or other sharp objects
such as scalpel blades should be discarded into specifically designated containers.
Disposable paper scrub suits and gowns are often easier to work with and more
cost-effective than cloth materials. If linen or other cloth scrub suits, gowns, or aprons are used
they may be collected into bags that can be directly laundered without removal of the contents
(bag dissolves in water).
The experience of the past decade in public hospitals and other centers performing large
numbers of AIDS autopsies has shown that AIDS is not a threat to pathologists or other
laboratory workers. There is no such thing as a "high risk" autopsy because the autopsy room
environment can be well controlled. It is also unlikely that requirements for unusual,
extraordinary, or unwieldy procedures will add a definable margin of safety, but such procedures
may lead to accidents or failure of compliance. A system of standard, routine procedures should
be followed at all times.[1094]
