Various drugs, including anesthetic agents, can cause parosmia in the perioperative period. There are reported cases of patients with alterations of smell and taste due to local anesthetics, nerve damage, or as a side effect of general anesthesia.
Alterations in taste and smell, including but not limited to anosmia, ageusia, hypogeusia, and dysgeusia, have been described in association with various medications, including anesthetic agents. Frequently, these symptoms occur 1-2 weeks after medication administration and last several months.
After a surgical procedure, many patients have shared that they experience an altered or metallic taste. This is most likely a temporary result of surgery, or in some severe cases, a permanent side effect of surgery.
There are two major changes in taste and smell function following general anesthesia – loss of acuity and presence of distortions. Most patients are surprised by the advent of these symptoms.
One study indicated that as high as 97% of patients experience changes in either taste, smell or tolerance of certain foods following surgery. And some people face a combination of all of these changes!
Anesthetic drugs can stay in your system for up to 24 hours. If you've had sedation or regional or general anesthesia, you shouldn't return to work or drive until the drugs have left your body. After local anesthesia, you should be able to resume normal activities, as long as your healthcare provider says it's OK.
A temporary change or loss of taste is normal, especially if your mouth has been anesthetized or if you have a condition such as gum disease or an infected tooth. To reduce your risk of taste loss, select a highly qualified dentist and practice good oral hygiene.
The time to emerge from anesthesia is affected by patient factors, anesthetic factors, duration of surgery, and painful stimulation. The principal factors responsible for delayed awakening following anesthesia are anesthetic agents and medications used in the perioperative period.
Sprinkling a pinch of baking soda on your toothbrush or rinsing your mouth with a half teaspoon of baking soda and water is a natural remedy to treat dysgeusia. It works by helping to regulate the pH balance, neutralizes acid, and effectively reduces metallic taste.
It may take several weeks for the gum tissue to grow over the socket. Food will probably get stuck in the socket until it has fully closed. This may cause problems with bad breath and a bad taste in your mouth. You can rinse with salt water (see page 4) to help keep your mouth clean.
It's common to experience a sore throat, dry mouth, bad breath and even hoarse voice after surgery, especially if you were intubated for general anesthesia. Anti-nausea drugs that are sometimes given to help prevent postoperative nausea and vomiting are also associated with dry mouth and a sore throat.
One of the first things you should ingest after surgery is clear liquids. These include water, soup broth, and fresh juice. You can add some full liquids as well, such as yogurt, and creamy cereals or soups. Even coffee and tea are fine in moderation, with or without milk or cream, depending on your dietary needs.
Medications for general anesthesia can cause smell alterations after surgery, with inhalation anesthetics being the most acknowledged drugs.
The surgery itself causes tissue injury. After surgery, your body undergoes repair and recovery, which drives a higher baseline metabolic rate and draws on your nutrient stores. So it isn't surprising such intense activity at a cellular level results in feeling tired after surgery.
While you are under anaesthesia your vital signs are constantly monitored to make sure you are 'asleep' and not feeling any pain.
If you're having general anesthesia, an anesthesiologist will give you medications that make you lose consciousness. After the surgery is complete, he or she will reverse the medication so that you regain consciousness — but you won't be wide awake right away.
Patients frequently report having dreams during general anesthesia. The incidence of dreams during general anesthesia that have been reported by patients upon awakening has been reported to range from 10 to 36% [1] and to be higher in younger patients, female patients [2], and patients who received ketamine [3].
Some common side effects that can occur after a general anaesthetic or some regional anaesthetics include: feeling or being sick. dizziness and feeling faint. feeling cold or shivering.
Numbness may also persist if the anaesthetic needle touches or penetrates the nerve that connects the tongue to the mouth. The anaesthetic solution can also inflame the mouth's nerves, causing lingering numbness in the tongue.
During a general anaesthetic, it is possible for your teeth to be damaged. This happens in about 1 in 4,500 general anaesthetics. Serious damage to the tongue is rare. Minor damage to the lips or tongue is very common.
Heartburn, acid reflux, and indigestion could be responsible for a metallic taste. Other symptoms you get with these conditions are bloating and a burning feeling in your chest after eating. To treat the underlying problem, avoid rich foods, eat dinner earlier, and take antacids.
