Is Facial Local Hemp Harmful To The Body

Local anesthesia is the injection of drugs into a local location when the patient is awake, which can temporarily block the conduction of sensory nerves in a certain part of the body, thus making the local sensation disappear. It's generally used for small operations where the drug doesn't get into the bloodstream, it doesn't get into the brain, so there's no damage to the brain.

There is a certain impact, so some doctors generally do not use anesthetic drugs, such as tooth extraction, look at the ear, especially the nose operation, which will affect people's intelligence

Local anesthesia is the use of local anesthetic drugs temporarily block the conduction of nerves in an area of the body to produce anesthesia, referred to as local anesthesia. Local anesthesia is simple, easy to operate, safe, can keep patients awake, less interference to physiological function, fewer complications.

It is suitable for small and medium-sized operation with superficial limitation. However, when it is used for surgery with large scope and deep site, pain relief is often not perfect, muscle relaxation is poor, and basic anesthesia or auxiliary anesthesia must be added when it is not easy to cooperate with patients, especially children, so its application scope is limited to a certain extent.

The axillary approach has a relatively small range of anesthesia, sometimes incomplete tickle block, and is suitable for surgery below the elbow (the patient is supine, the upper arm of the affected limb is extended 90 degrees, the forearm is flexion and external rotation, the palm is placed under the head. At the lower edge of the insertion of the humerus end of the pectoralis major, the pulse of the axillary artery is contacted and traced towards the apex of the axilla to the highest beating position, which is the puncture point.

The axillary artery was fixed with the left index finger, and the 22G injection needle was held in the right hand and inserted along the upper part of the axillary artery. When passing through the axillary fascia, there was often a sense of loss of resistance or abnormal sensation, and the needle pulsated with the axillary artery, indicating that the needle had entered the axillary sheath tube, the depth was about 1 ~ 1.5 cm, and no blood was drawn back, and anesthetic drugs could be injected.
