Application：

pure lidocaine powder is a local anesthetic and can also be used for the emergency treatment of ventricular arrhythmia. With people's in-depth research on lidocaine, it is found that it also shows better effects in the treatment of other diseases. This will be summarized below.

1. Treatment of vestibular neuritis Lidocaine can block the excitability of the sympathetic nerves of blood vessels, reduce its contraction of vascular smooth muscle, increase the excitability of parasympathetic nerves, and achieve the purpose of improving blood microcirculation. It can improve the blood supply of the blood vessels around the vestibular nerve of the inner ear and eliminate the obstacle of endolymphatic reflux. Method: Lidocaine 50-100 mg intravenously, 200-400 mg in severe cases add 5% glucose intravenously, once a day, 3 days as a course of treatment.

2. Prevention of cardiovascular response during tracheal extubation. Endotracheal intubation of general anesthesia patients should be removed at the end of the operation by reducing the dose of anesthetic until the laryngotracheal reflex is restored. Cardiovascular reactions similar to those of intubation can occur during extubation, and it can also cause coughing, which is extremely unfavorable for patients with hypertension, coronary heart disease, and high intracranial pressure. Lidocaine can prevent this reaction, the usage is lidocaine 1.5 mg/kg intravenously. The mechanism is related to central depression or depression of the heart.

3. Treatment of severe convulsions in newborns For recurrent seizures, the first load of lidocaine is 2 mg/kg, plus the initial maintenance dose of 6 mg/kg intravenously per hour, and the dose is gradually reduced within 3 days.

4. For gastroscopic intubation inspection Put 2% lidocaine into the mouth, swallow slowly for 5 minutes, and perform intubation inspection after 10 minutes. Compared with the 2% tetracaine spray method, lidocaine has the advantages of saving time, simplicity, and less pain, and lidocaine has a sedative effect, which can eliminate the nervousness of the patient, reduce gastric secretion and gastric motility.

5. Treatment of acute gastric abdominal pain Acute gastric abdominal pain is mostly caused by acute indigestion and increased gastric acid secretion, mucosal congestion, edema and even spasm. Oral lidocaine can relieve this kind of pain, and the usage is 2% lidocaine 15 mg orally.

6. Treatment of epilepsy Lidocaine can pass through the blood-brain barrier, excitement and then inhibit central neuron activity, and can block the transmission of nerve and muscle junctions. It is effective for status epilepticus. Diluted with 0.1g lidocaine and injected intravenously, the seizure will stop, and the recurrence will still be effective after re-administration.

7. Treatment of asthma. Lidocaine is a powerful inhibitor of irritating cough, and it can also inhibit bronchial asthma. Method: 5 ml (100 mg) of lidocaine was inhaled by aerosol, once a day, breathing and heart rate returned to normal, wheezing disappeared, and the recovery time of arterial blood gas was significantly shorter than that of the control group.

8. Treatment of hiccups The mechanism of lidocaine in the treatment of hiccups may be related to its blocking effect on peripheral and central nerve conduction. Usage: Add 100 mg of lidocaine to Murphy's dropper, then add 500 mg of 10% glucose to maintain an intravenous infusion at a rate of 30-40 drops/min. After hiccups are controlled, maintain it for 1 to 2 days.

9. Treatment of renal colic. Lidocaine has antispasmodic, dilated ureter and mild analgesic effects, which can relieve renal colic. Dilute with 100 mg of lidocaine and push it intravenously, and then give another 200 mg to the infusion for intravenous infusion.

10. Non-inhibited bladder contraction after treatment. Lidocaine can penetrate the mucosa to block the conduction of peripheral nerves, and is made into a glue for administration in the rectum, which can block the nerve conduction of the detrusor muscle and inhibit the non-inhibition of the detrusor muscle. shrink. Usage: Rectal administration with verapamil 40 mg, 5 minutes later, and then rectal infusion of 20 ml 2% lidocaine, the effective rate (71%) is higher than that of the verapamil group (38%).
