How ammonia leak emergency?
1. If the patient decontamination simply contacting ammonia , and no skin and eye irritation, you do not need decontamination. If contact is ammonia, and clothing has been contaminated, it should take off your clothes and put into a double plastic bag. If eye contact or eye irritation, rinse with plenty of water or saline over 20 minutes. If flushing occurs when blepharospasm, should slowly drip 1–2 drops of 0.4% oxybuprocaine continue to rinse thoroughly. If patients wearing contact lenses, and easy to remove and will not damage the eyes, they should remove the contact lenses. Response to contact with the skin and hair with plenty of water at least 15 minutes. Flushing of the skin and hair need to protect the eyes. 2. Patients should immediately revive the victim out of the contaminated area, three-step method of recovery of the patient (airway, breathing, circulation): Airway: to ensure that the airway is not blocked by the tongue or a foreign body. Breathing: check whether the patient is breathing, if no breathing masks available to provide ventilation pocket, loop: check pulse, if no pulse should perform CPR.3. Initial treatment of ammonia poisoning no specific antidote should be used to support the treatment. If the exposure concentration ≥ 500ppm, and the emergence of eye irritation, pulmonary edema symptoms, it is recommended to take the following measures: first spray five times dexamethasone (with metered dose inhalers), then sprayed twice every five minutes, until you reach the hospital emergency room so far . If the exposure concentration ≥ 1500ppm, venous access should be established, and intravenous injection of 1. 0g methylprednisolone (methylprednisolone) or equivalent steroids. (Note: In controlled clinical studies, the role of corticosteroids has not been confirmed.) For ammonia inhalation, should give humidified air or oxygen. If symptoms of hypoxia, oxygen should be given wet. If respiratory distress, intubation should be considered. When the patient’s condition can not be intubated, as conditions permit, the ring should be implemented thyroid cartilage incision. For patients with bronchial spasm, can give a bronchodilator spray, such as terbutaline. If skin contact with ammonia, can cause chemical burns, thermal burns can be treated: proper rehydration, analgesics to maintain body temperature, cover the wound surface with a sterile pad or clean sheets. If skin contact with high-pressure liquid ammonia, pay attention to frostbite. http://www.newradargas.com/details/13371083.shtml
