Monitored anesthesia care (MAC) means that an anesthesia specialist will care for you during your surgery. He or she will make sure that you get only the level of anesthesia you need to prevent pain for your specific case. MAC can be used instead of always giving general or regional anesthesia. MAC is often combined with local anesthesia for smaller procedures. That means you will be numb in the area being operated on.
Sedation with MAC can make you feel sleepy and relaxed. A doctor or a nurse who is trained to give anesthesia will closely watch you during surgery. He or she may adjust the medicine if needed so that you stay safe and comfortable. You may not remember much about the surgery after.
There may be fewer side effects than with other types of anesthesia. It can also help you recover more quickly.
An anesthesia specialist will talk to you before the surgery. He or she might ask about your health, past surgeries, medicine you take, and your family history, and your feelings about the surgery. He or she will help you decide if MAC is right for you.
You will get an IV, which lets medicine into your vein through a tube. You may get:
You might also get a shot to make the area near the surgery numb.
You will get a list of things to do to help you prepare for your surgery. You will learn about when to stop eating and drinking. If you take medicine, you will learn what you can and can't take before surgery.
You will be asked to sign a form that says you understand the risks of anesthesia. Before you sign it, your doctor will talk with you about sedation with MAC. He or she may talk about other types of anesthesia as well. You will learn about the risks and benefits of each type.
You may be told that the doctor may need to change from MAC to general anesthesia during surgery to keep you comfortable and safe.
Many people are nervous before they have surgery. Ask your doctor about ways to relax. These may include relaxation exercises or medicine.
Major side effects aren't common. But all types of anesthesia have some risk. Your risk depends on your overall health. It also depends on the type of anesthesia you have and how you respond to it.
Serious but rare risks include breathing problems, heart attack, stroke, and a bad reaction to the medicine.Some health conditions increase the risk of problems. Your doctor will find out about any health problems you have that may affect your care.
Your doctor or nurse will closely watch your vital signs during surgery. This includes checking your breathing, blood pressure, and heart rate. This may help you avoid problems from anesthesia.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
