We treated a total of 67 patients for mamushi viper (Gloydius blomhoffii) bite during a 10-year period between 2007 and 2016. The mean age of the patients was 68 years, with those aged ≧ 60 years accounting for about 80% of all patients. Most injuries occurred between July and September in rice fields and other cropland, or in the patients' homes. Except for 1 severe case who developed a marked thrombocytopenia immediately after the incident, the remaining 66 patients were included in the analysis. All patients received inpatient care, with a mean hospital stay of 6.8 days. There was a significant positive correlation between the size of the swelling at the bite site and the length of hospital stay. Kidney dysfunction occurred in 3 patients, 1 of whom died. The mean time to the largest swelling was 21.8 h while the mean time to the highest creatine phosphokinase level was 2.6 days. The more severe cases were more likely to be have been treated with mamushi antitoxin while 2 of the 3 patients with kidney dysfunction, including the 1 fatality, were not, suggesting that the use of mamushi antitoxin is essential in severe cases. We also report a very rare case of mamushi viper bite complicated by thrombocytopenia.
