Abstract:
Objective:To conduct a characteristic analysis of the case of acute hydrogen sulfide poisoning in fishing boats for nearly ten years in a city, and to research on prevention and control measures, so as to provide scientific basis for formulating prevention strategies.
Methods:In July 2018, collecting the data of acute hydrogen sulfide poisoning in fishing boats recorded by the Oceanic and Fishery Department & Health Sector from January 1, 2009 to June 30, 2018, the accident characteristics of acute hydrogen sulfide poisoning in fishing boats was analyzed, and compared the differences of hydrogen sulfide poisoning under different classification statistics.
Results:In the past ten years, there were 14 acute poisonings in the city, 34 people were poisoned and 12 deaths (the case fatality rate was 35.3%) . According to the types of fishing vessels, the majority number of acute hydrogen sulfide poisoning incidents, poisoned persons and deaths occurred on fishing boats, accounted for 71.4% (10/14) , 76.5% (26/34) and 75.0% (9/12) respectively. From the location of the accident, 85.7% (12/14) of the acute hydrogen sulfide poisoning incidents occurred outside the fishing port. Fisher's exact test showed that the case fatality rate in within the fishing port was higher than that outside the fishing port (P=0.008) . From the cause of direct poisoning, the first three reasons were enter the fish room to rescue, enter the fish room to move fresh catch, to clean the fish room. The poisoning showed seasonal changes, Fisher's exact test showed that the fatality rate in summer was significantly higher than that in spring (P=0.044) , but there was no statistical significance in other seasons (P>0.05) .
Conclusion:The acute hydrogen sulfide poisoning of fishing boats in this city has a high case fatality rate, frequent collective poisoning, and showed seasonal changes. Blind rescue, incomplete facilities, and inadequate system are important factors leading to poisoning, so daily measures and rescue measures should be strengthened to reduce the occurrence of poisoning and casualties.
