Warning: Sleep Apnea & Anesthesia Aren’t A Good Combination
If you suffer from sleep apnea, you need to be aware of the risks of anesthesia. While there are many real and potentially serious concerns, the negative effects of anesthesia can be minimized or even eliminated with the proper procedures and careful monitoring.
What Should I Do?
If you need surgery, it’s important to make sure that the anesthesiologist is aware of your condition. Certain precautionary measures would have to be taken to insure that breathing difficulties will not jeopardize your time under anesthesia. In obstructive sleep apnea, the throat muscles relax, thereby closing or narrowing the airway. This, in turn, interrupts the normal flow of oxygen to the lungs, which affects the brain.
The brain will sense the reduced lack of oxygen and will signal you to wake up. When you are under anesthesia, this is not possible. Being under anesthesia also contributes to more interrupted breathing spells. When an anesthesiologist has a patient with sleep apnea, he will take special care to keep airways open. Close monitoring is kept on the patient in surgery and in the recovery room.
Side effects from anesthesia can linger for hours after surgery so constant care is given to the patient during this time. A Continuous Positive Airway Pressure (CPAP) machine may be used to ensure the airways remain open for an even, continuous flow of oxygen. Generally as the body adjusts to the medications given for surgery, the immediate dangers will pass. In some severe cases, mechanical ventilation may need to be given.
Should I Cancel My Surgery?
Theres no reason to cancel a surgery because of potential problems as long as youve made your medical personnel aware of your sleep apnea disorder. This will allow them to plan for the monitoring needed during surgery and immediately afterward.
It should be noted that many times people are not aware that they have sleep apnea, which can cause complications in surgery. If you are not sure you have this condition, or if you suspect that you do, a few simple questions may lead you to an answer. Do you snore? Do you feel tired and groggy in the mornings? Do you fall asleep during the day? If you can answer “yes” to these questions, perhaps you should speak to your doctor about the possibility of sleep apnea. Diagnosing sleep apnea before having anesthesia is a crucial first step to your total recovery.
