Yes.

The drugs used for local anesthesia are single, with limited effects and little impact on the whole body. However, once the local anesthetic is absorbed into the blood in large quantities, it can cause side effects on the central nervous system and circulatory system. The most serious ones can even Cause cardiac arrest. Therefore, the application dosage of local anesthetics is conditional. For example, the safe dosage of lidocaine is 3 mg/kg body weight (after adding epinephrine to reduce blood penetration, it can be relaxed to 7 mg/kg body weight).

Precautions for general anesthesia

Pay attention to the patient's state of consciousness: Because it takes a period of time to metabolize anesthetic drugs, after the patient wakes up, it does not mean that the anesthetic drugs in the body are completely metabolized. The metabolism of anesthetic drugs takes 12-24 hours, so the patient's state of consciousness during surgery is the first issue to pay attention to.

Comprehensive monitoring of patients: Patients should be comprehensively monitored with multi-functional monitors, including non-invasive blood pressure, heart rate, blood oxygen saturation and body temperature.
