As latex proteins, which cause latex hypersensitivity, can be found on starch particles and inhalation may be a route for sensitization, the presence of starch particles in hospital air was examined. The starch particles were demonstrated by immobilization onto cellulose acetate filters and staining with iodine. Rooms in which powdered latex gloves were used gave counts of up to > 3,667 particles per cubic meter of air. Starch particles were not found in the air in rooms where latex gloves were not used, and were highest in rooms with a high glove usage but no ventilation. A change to powder-free gloves significantly reduced the count of starch particles in the unventilated Accident/Emergency Department air. Use of powder-free gloves should be considered especially in unventilated areas in healthcare premises.
由于可在淀粉颗粒上发现会引发乳胶过敏的乳胶蛋白，且吸入可能是致敏途径，因此对医院空气中淀粉颗粒的存在情况进行了检测。淀粉颗粒通过固定在醋酸纤维素滤膜上并用碘染色来显示。使用含粉乳胶手套的房间每立方米空气中的颗粒计数高达3667个以上。未使用乳胶手套的房间空气中未发现淀粉颗粒，在手套使用量大但无通风的房间中淀粉颗粒最多。更换为无粉手套可显著减少未通风的急诊部空气中淀粉颗粒的计数。尤其是在医疗场所的未通风区域，应考虑使用无粉手套。
