Abstract
In response to a request from a physician with the Cincinnati Sportsmedicine and Orthopedic Center (SIC-8011), Cincinnati, Ohio, an investigation was begun into possible hazardous working conditions at that facility. Concern was expressed about carbon- dioxide (124389) exposures during the wearing of surgical isolation suits. Operating room personnel had reported headaches, irritability, discomfort and sweating while using the suits. The suits were introduced in orthopedic surgery to prevent the infection of patients by operating room personnel. Four types of surgical helmets were tested along with two powered air purifying respirators. Mean carbon-dioxide concentrations during 15 minute tests with light exercise ranged from 5,500 parts per million (ppm) to 11,700ppm. The results of this study indicated that if these surgical helmets and powered air purifying respirators (PAPR) were used during operations lasting more than 8 hours, the users would be exposed to carbon-dioxide levels in excess of the 8 hour time weighted average exposure limit of 5,000ppm. At the highest mean carbon-dioxide level measured, 11,700ppm, the user would be overexposed after 3.5 hours. The authors conclude that wearing a surgical helmet or PAPR during orthopedic surgery could result in a user being overexposed to carbon-dioxide, depending on the duration of the surgery. The authors recommend measures to reduced symptoms during surgery.
