Abstract

Clinical, pulmonary function and blood gas studies carried out in symptomatic Methyl Iso-cyanatc exposed individuals 1-2 months after exposure had revealed that 40% of them had ventilatory impairment. The predominant type of ventilatory defect was combined obstruc-tion and restriction. Five percent of patients with normal physical findings and. normal chest X-rays had abnormal pulmonary function. Arterial hypoxia (PaO2 < 85 mm Hg) was obseived in 69% °f patients in whom blood gas analyses were done. Arterial hypoxia and ventilatory abnormalities were predominantly seen in severely exposed patients. Further studies are re-quired to identify the sub-group of patients with Reactive Airways Dysfunction Syndrome. Long term follow up is essential to identify the pulmonary syndromes due to MIC exposure.
