Introduction: In the Middle Niigata prefecture earthquake 2004 in Japan, 500 thousands of houses were broken. More than 100 thousands quake-hit residents stranded in small compact cars like Kei-jidosya having 660cc displacement, 11.15 feet long by 4.86 feet width. They had to remain in a seated position every day continuously in this car (sleeping, eating, etc). 11 residents had pulmonary embolism and 4 of them died immediately after getting out of their cars. We attempted to detect DVT in quake-hit area by portable ultrasound and measured D dimer or fibrin monomoer complex.
Methods: We used portable ultrasound machine with 7-10 MH liner probe. Plasma fibrin monomer complex (FMC, Nissui Pharmacy) were measured in quake hit residents.
Results: When we examined legs by portable ultrasound machine a week after the quake in 69 quake-hit residents who stranded in cars, DVT was determined in 22 of them. All the residents with DVT stranded in cars more than 3 days. When we examined blood sample in quake-hit residents within a week. fibrin-monomer complex (FMC) of residents stranded in cars was 10.34.2 micro g/mL(n=40), that of stranded in public evacuated area was 5.90.7 micro g/mL(n=20), that of stayed in home was 6.11.4 micro g/mL(n=41). FMC of residents stranded in cars were significantly higher than that of others (p<0.01). FMC of residents stranded in cars for a day was 4.52.0 micro g/mL (n=61), for two days was 4.101.10 micro g/mL (n=39), for three days was 9.12.6 micro g/mL (n=38), for four days was 8.42.6 micro g/mL (n=59).
Conclusions: In large earthquake, stranding in cars increase a risk of DVT. Portable ultrasound machine is useful for examine DVT in quake-hit area.
