What Causes Mouth and Throat Issues After Surgery? Mouth and throat irritation may result from surgeries that involve the mouth, nose, and throat. Any surgery that requires intubation, which is when a tube is placed in the mouth and down the airway can also lead to mouth and throat discomfort. Examples of surgeries that may require intubation include emergency, cosmetic, heart, or lung. There are several reasons why mouth and throat issues may happen. Under general anesthesia, an individual may be intubated. While the breathing tube remains in place, the mouth is partially open. This can cause dry mouth, chapped lips, and bad breath. Because the tube extends into the throat it can also cause a sore throat and throat irritation. Even the tape used to keep the tube in place can cause your lips to become chapped. Muscle relaxants, which prevent movement, may be used during general anesthesia and can cause dry mouth. Anti-nausea drugs may also be given during general anesthesia to help prevent postoperative nausea and vomiting. However, these medications are associated with dry mouth and a sore throat. Drug and Medication Side Effects How Do You Treat Mouth and Throat Issues? In general, good mouth care is a crucial first step in reducing uncomfortable symptoms. If you are on a ventilator, a machine that helps with breathing, mouth care may be done every two hours by the medical staff. This can help reduce ventilator acquired pneumonia, which is a potentially deadly infection. If you're not on a ventilator, brush your teeth and tongue twice a day to help with dry mouth and lips, as well as bad breath. Why Do I Have a Sore Throat After Surgery? Dry Mouth and Lips Staying hydrated and using a humidifier, a device that adds moisture to the air, can help with dry mouth post-surgery. You may also want to avoid alcohol, tobacco, and caffeine as they can make your mouth even dryer. If your lips are very dry or scaly feeling, gently scrub them with a moist washcloth. This will remove any dead skin. Next, apply a generous amount of lip balm or petroleum jelly to help soften lips. Frequent reapplication, along with drinking lots of fluids, will help your lips feel better. How to Eat Well Despite Having Dry Mouth Sore Throat To help with a sore throat: Use cough drops with benzocaine or menthol in them to help numb the throat and reduce pain.
