tetrodotoxin poisoning
Administer supplemental oxygen and assist ventilation as needed.
First stage: Numbness and sensation of prickling and tingling (paresthesia) of the lips and tongue, followed by facial and extremity paresthesias and numbness, headache, sensations of lightness or floating, profuse sweating (diaphoresis), dizziness, salivation (ptyalism), nausea, vomiting (emesis), diarrhea, abdominal (epigastric) pain, difficulty moving (motor dysfunction), weakness (malaise), and speech difficulties. On April 17, 2001, an outbreak of TTX poisoning occurred among Mainland Chinese fishermen who shared puffer fish on their boat in the Taiwan Strait. We report an outbreak of six cases of TTX poisoning from eating puffer fish. On April 17, 2001, an outbreak of TTX poisoning occurred among Mainland Chinese fishermen who shared puffer fish on their boat in the Taiwan Strait. Tetrodotoxin poisoning: a clinical analysis, role of neostigmine and short-term outcome of 53 cases. Therefore, for those TTX-intoxicated patients without immediate prominent respiratory insufficiency, at least 24 hours of intensive monitoring of their respiratory state is necessary because of the different susceptibility and unpredictability of an individual course. Second stage: Increasing paralysis, first in the extremities, then in the rest of the body, and finally in the respiratory muscles; difficulty breathing or shortness of breath (dyspnea); abnormal heart rhythms (cardiac dysrhythmias or arrhythmia); abnormally low blood pressure (hypotension); fixed and dilated pupils (mydriasis); coma; seizures; respiratory arrest; and death. Indoor Air: Because the natural source of tetrodotoxin is from living organisms, and manufacturing tetrodotoxin artificially in appreciable quantities is extremely difficult, dissemination through indoor air is unlikely. Oral Chronic Toxicity of the Safe Tetrodotoxin Dose Proposed by the European Food Safety Authority and Its Additive Effect with Saxitoxin. A NIOSH-certified CBRN full-face-piece SCBA operated in a pressure-demand mode or a pressure-demand supplied air hose respirator with an auxiliary escape bottle. Only three cases have been reported in the EM literature.
TTX is extremely toxic. Woolf AD, Erdman AR, Nelson LS, Caravati EM, Cobaugh DJ, Booze LL, Wax PM, Manoguerra AS, Scharman EJ, Olson KR, Chyka PA, Christianson G, Troutman WG.
Favorable outcomes in most patients can be obtained if aggressive supportive treatment is provided in time.

Escape mask, face shield, coveralls, long underwear, a hard hat worn under the chemical-resistant suit, and chemical-resistant disposable boot-covers worn over the chemical-resistant suit are optional items. Place all PPE in labeled durable 6-mil polyethylene bags. TTX is even more dangerous if injected; the amount needed to reach a lethal dose by injection is only 8 μg per kg in mice. Remove the SCBA after other PPE has been removed.

Tetrodotoxin (TTX) poisoning, although uncommon, is frequently seen in Taiwan, Japan, and Southeast Asia. Horie M, Kobayashi S, Shimizu N, Nakazawa H [2002]. Clin Toxicol (Phila). | A NIOSH-certified CBRN PAPR with a loose-fitting face-piece, hood, or helmet and a filter or a combination organic vapor, acid gas, and particulate cartridge/filter combination or a continuous flow respirator for air levels greater than AEGL-1. Nausea, vomiting, diarrhoea and epigastric pain may also be present.
Cover the patient/victim to prevent shock and loss of body heat. Tetrodotoxin (TTX) poisoning, although uncommon, is frequently seen in Taiwan, Japan, and Southeast Asia. For information on who to contact in an emergency, see the CDC website at emergency.cdc.gov or call the CDC public response hotline at (888) 246-2675 (English), (888) 246-2857 (Español), or (866) 874-2646 (TTY). Remove all clothing (at least down to their undergarments) and place the clothing in a labeled durable 6-mil polyethylene bag. A hooded chemical-resistant suit that provides protection against CBRN agents. It is rare but significant in the United States as well.
Remove the patient/victim from the source of exposure.
Prevent others from eating until the source of tetrodotoxin exposure can be ascertained, in order to avoid more casualties.
We report an outbreak of six cases of TTX poisoning from eating puffer fish. Do not touch or walk through the spilled agent if at all possible.
See the PPE section of this card for detailed information. Coveralls, long underwear, and a hard hat worn under the TECP suit are optional items. Only three cases have been reported in the EM literature. Water: Because the natural source of tetrodotoxin is from living organisms, and manufacturing tetrodotoxin artificially in appreciable quantities is extremely difficult, dissemination through water is unlikely. The remaining patients survived without significant sequelae and were discharged after short-term observation and supportive care, although some had neurologic and cardiopulmonary manifestations (muscle weakness, hypotension, hypoxemia, and hypercapnia). It is rare but significant in the United States as well. Methylphenidate poisoning: an evidence-based consensus guideline for out-of-hospital management. Paraesthesia appears in the face and extremities, which may be followed by dizziness or numbness.
