Summary
Sea snake bites, primarily affecting fishermen, had a 10% mortality rate before antivenom. Specific sea snake antivenom dramatically improved outcomes for patients with serious envenomation, with 80% recovery.
Area of Science:
- Marine Biology
- Toxicology
- Tropical Medicine
Background:
- Sea snake bites pose a significant risk, particularly to fishermen in regions like Malaya.
- Sea snake venom is highly toxic, leading to severe envenomation in some cases.
- Historically, treatment options were limited, contributing to a notable mortality rate.
Purpose of the Study:
- To evaluate the effectiveness of sea snake antivenom in treating patients with sea snake bites.
- To determine appropriate dosages of sea snake antivenom for varying severity of envenomation.
- To analyze the outcomes of sea snake bite patients before and after the availability of specific antivenom.
Main Methods:
- Retrospective analysis of 101 patients bitten by sea snakes between 1957-1964.
- Comparison of mortality rates before and after the introduction of sea snake antivenom.
- Case review of patients receiving specific sea snake antivenom for serious envenomation.
Main Results:
- Before antivenom, 10% of patients died, with 6 out of 11 severe cases being fatal.
- Following administration of sea snake antivenom to 10 patients with serious poisoning, 8 recovered dramatically.
- Two moribund patients showed temporary improvement but ultimately succumbed despite antivenom treatment.
Conclusions:
- Specific sea snake antivenom is highly effective in treating serious sea snake envenomation.
- Recommended dosages range from 1000-2000 units for mild poisoning and 3000-10,000 units for severe cases.
- Sea snake antivenom significantly reduces mortality and improves patient outcomes.
