He had the same treatment as his wife. Due to the severity of the clinical status and because of the previous ventricular fibrillation, he underwent coronary angiography, which resulted, as expected, negative (coronary arteries).

The patient was sedated and subjected to controlled ventilation until the next morning when the pharmacological sedation was suspended. When he gained consciousness and started breathing well, he was extubated and left in spontaneous breathing.

After 12 hours he was transferred to department of internal medicine and was discharged 48 hours later.

3. Discussion

The poisoning occurs because of an inadequate cooling and poor preservation of the fish caught. It is found mainly in warm or temperate waters particularly in countries lacking infrastructure for the preservation and storage of food.For 40 years, the state has protected manatees by setting up slow speed zones for boaters.

The logic behind it was the same as speed zones around schools: Make people slow down and they're less likely to hit something.

But in the 1990s, a scientist named Edmund Gerstein announced a startling discovery: Slowing boats down was actually bad for manatees. He said his research on manatees at Tampa's Lowry Park Zoo showed they couldn't hear slow boats, only fast ones.

Boaters and lawmakers were quite taken with Gerstein's study. The state funneled tens of thousands of dollars into more research — which repeatedly contradicted his research. The new research found that manatees don't have any trouble hearing
