What are the dangers of taking too much anesthesia?

If too much anesthetic is injected, the impact on the patient will naturally be relatively large, and it may even easily lead to some more serious conditions. Of course, with the advancement of medical technology, the accuracy of anesthetics is getting higher and higher. Before anesthesia is administered, a pre-operative visit is required, which can reduce the risk of anesthesia. In addition, when anesthesia is administered during surgery, the anesthesiologist also plays a very good role.

Are anesthetics harmful to the human body?

Certain Facts The dangers of anesthesia are well known. In general, people who are very sick, very young, or elderly have an increased risk of anesthesia-related death, usually due to general anesthesia that causes coma. In addition, certain conditions may increase the risk of anesthesia. People with heart disease, brain damage, or a malfunctioning liver may be at greater risk for surgery than those who are healthy.

The most common anesthesia danger is an allergic reaction to one of the medications. This is also usually noted and addressed immediately, as most patients undergoing general anesthesia are constantly monitored. People with allergic reactions to local anesthesia may react immediately to it. Dentists and doctors who use local anesthetics have emergency supplies on hand should an allergic reaction occur.

Some of the most common side effects of general anesthesia include your mental and physical health. As the general anesthetic begins to wear off, many patients experience confusion or disorientation or have trouble thinking clearly. Dry mouth and feelings of dehydration are typical side effects, as are nausea and vomiting. Some patients may feel cold because their body temperature has dropped.

Preoperative treatment for local anesthesia

1 Preoperative visit It must be emphasized that the patient's preoperative preparation is a key factor in determining the success of local anesthesia. Preoperative visits allow the anesthesiologist to establish a close relationship with the patient and ensure the patient's cooperation, thus making local anesthesia operations easier. It is of great help to the anesthesiologist if he or she has had experience with local anesthesia. If an abnormal sensation is to be induced during the nerve block procedure, the patient should be informed in detail of the issues related to the abnormal sensation. If the patient will remain awake during surgery, the anesthesiologist should carefully explain to the patient that they may still have some sensation during surgery and that they may be able to feel movement, warmth, or cold; otherwise, the patient may interpret various stimuli as pain, causing the anesthesiologist to take unnecessary measures on the patient.

A good approach to the preoperative visit is to: ① point out to the patient the advantages of the chosen local anesthetic method - early recovery, no postoperative pain, low incidence of nausea and vomiting, etc.; and ② explain to the patient what he will experience before, during, and after the nerve block. Anesthesiologists often need to reassure patients that they will not see the surgical procedure during surgery. In addition, anesthesiologists should inform patients that motor nerve blockade after surgery may last longer than sensory nerve blockade.

2 Patient preparation As with patients under general anesthesia, patients undergoing extensive nerve block should be fasting from midnight on the day of surgery. Patients scheduled for a peripheral nerve block may eat a light meal, such as tea and toast, 4 hours before the scheduled start of surgery. Patients may be allowed to take their normal medications at regular times with a sip of water if there are no contraindications.

3 Premedication Although some patients do not need premedication after a preoperative visit by the anesthesiologist and a detailed explanation of the proposed local anesthetic procedure, most patients need to use premedication.

4 Commonly used drugs Opioids: Patients with fractures or other painful diseases require analgesic treatment. This can make patient transfer to the operating room and positioning for neurological procedures involving local anesthesia less painful. In this setting, opioids are well suited, although these drugs have many properties that are unfavorable to patients undergoing local anesthesia.
