Health hazard evaluation report: HETA-93-0582-2359, HCA Wesley Medical Center, Wichita, Kansas.
NIOSH 1993 Oct; :1-13
In response to a request from the respiratory therapist educator of HCA Wesley Medical Center in Wichita, Kansas, an evaluation was conducted of the effectiveness of revised procedures for administering ribavirin (36791045) via hood. The containment system consisted of a cubical care cube disposable hood, an aerosol generator for ribavirin administration, and a second hood which was placed over the care cube and connected to a scavenging system. Air sampling was conducted within the care cube disposable hood, and area air samples were collected at five locations within the room. A respiratory therapist simulated the activities that would normally have been necessary if a patient were actually receiving care, but did so using an infant mannequin. Area samples showed either nondetectable or trace concentrations of ribavirin. In hood concentrations of ribavirin ranged from 33 to 92mg/m3. The air exchange rate of each room exceeded the minimum of six air changes per hour. The author concludes that the double hood system in place appeared to be effective for preventing the release of ribavirin aerosol into the work environment. The author suggests that the ventilation system of each room where ribavirin is administered be monitored on a routine basis to ensure that optimal operation is maintained.
