Symptoms of anesthetic poisoning

summary

Local anesthetics are divided into lipid local anesthetics and amide local anesthetics. Procaine, chloroprocaine, tetracaine and cocaine are the local anesthetics of lipids; Lidocaine, mepivacaine, bupivacaine, etivacaine, procaine and ropivacaine are amide local anesthetics. As local anesthesia, nerve block, spinal anesthesia and intravenous anesthesia, the causes of poisoning are different, but the symptoms, signs and treatment of poisoning are basically similar. Symptoms of anesthetic poisoning? Let's talk about it

Symptoms of anesthetic poisoning

Mild poisoning includes dizziness, multilingualism, shivering, ruddy complexion, elevated blood pressure and accelerated pulse. After such drugs enter the blood vessels, there are tinnitus, headache, sweating and other symptoms. Due to the decrease of myocardial contractility, slow heart rate, decreased cardiac output, there are pale complexion, cold limbs, sweating, pulse speed, blood pressure drop and other shock syndrome. Coma or convulsion.

The patient with moderate poisoning is restless, nausea and vomiting, involuntary muscle twitch or tremor of limbs, eyeballs and face, mild cyanosis, high blood pressure and slow pulse. The expression is apathy, drowsiness or coma. Blood pressure gradually decreased, tachycardia gradually decreased, heart rate was slow, heart sound was low and weak. The breathing is shallow and slow to stop completely.

Muscle convulsions in severe poisoning patients were generalized tonic, clonic convulsions, frequent cyanosis and dyspnea. In addition to the above symptoms and signs, there may be rash, urticaria, mucosal edema, laryngeal edema, bronchospasm or acute pulmonary edema. The difference from toxic reaction is that the dosage is very small and the serious reaction similar to poisoning appears immediately.

matters needing attention

1. Stop the medication, keep the respiratory tract unobstructed, mask oxygen. Mild toxic reactions are mostly transient, which can be observed by oxygen inhalation, and can recover quickly without special treatment. 2. In case of irritability, panic, muscle convulsion, convulsion, the author can give intravenous injection of thiopental sodium, diazepam or midazolam, and at the same time, the mask is pressurized with oxygen to assist breathing. If the convulsion is serious and has not been controlled, short acting muscle relaxants can be used in addition to tracheal intubation to establish artificial ventilation.
