  • Look Inside

 We studied the formation of pulmonary edema on 9 patients with paraquat poisoning using thermalsodium double indicator dilution method for the measurement of lung water.

 In survivors group (n=4) extravascular thermal volume (EVTV) was not almost changes. In non-survivors group (n=5) EVTV increased about three times as much as that in survivors group on 32 hours after admission. EVTV was correlated with PCP-PCOP in both survivors group and non-survivors group (n=64, r=0.665, p<0.01). But EVTV in non-survivors group was higher than that in survivors group within same PCP-PCOP. In non-survivors group ΔEVTV/Δ (PCP-PCOP) in 24 hours after ad-mission was correlated with initial PCP-PCOP (r= O.984, p<0.01). We propose that the formation of pulmonary edema on paraquat poisoning is mainly due to the increased capillary permeability, influenced by the increased pressure gradient of capillary bar-rier.
