What Are the Signs of an Allergic Reaction to Ant Bites?

I was diagnosed by an ant bite for 1 hour while outdoors. Physical examination: BP80 / 60mmHg, body flushing, rash, fist-sized nuggets, clear mind, and itchy skin. Diphenhydramine 20mg was intramuscularly administered as directed by the doctor, and he was in a coma with anaphylactic shock. Immediately take the supine position, inhale oxygen at a medium flow rate, and then quickly inject 1 mg of epinephrine hydrochloride subcutaneously, 10 mg of dexamethasone intravenously, and intravenous drip of normal saline plus dopamine. After the above emergency treatment, throat edema quickly reduced, secretions decreased, and respiratory Ventilation improved, consciousness returned, and blood pressure gradually increased.

Clear the mouth and respiratory secretions to keep the airway open. And given the medium flow to suck O 2 to ensure blood oxygen saturation.

3 Quickly establish venous channels and maintain effective circulation. Due to the sudden increase in blood vessel volume, the effective blood circulation volume has decreased sharply. The rapid establishment of venous channels to supplement blood volume is a key item in anti-shock measures. It can be replenished in time to make up the effective circulating blood volume in a short time. Once the patient is in shock, venipuncture becomes more difficult. Must have skilled nursing skills, such as rapid venous access.

4 Closely observe the condition, maintain normal vital signs, closely observe the patient's conscious expression, judge the cerebral blood flow perfusion and the degree of hypoxia, closely observe the 24h urine volume, record the hourly urine volume, measure blood pressure and pulse every 15min, and record .
