Many patients have the impression that the anesthesiologist is the man/woman who jumps in for 30 seconds before the surgery, and I think that impression is somewhat on reality. I have a bit of a longer talk with the patients, but I have found they really appreciate this. I have found that as you explain the type of anesthesia you are going to use, the risks naturally come out.
Sometimes I use a straightforward list, such as, "The risks of anesthesia include, but not limited to, death, disability, brain, breathing and heart problems of all different kinds, other organ problems, nerve problems, drug reactions. Then the smaller ones include nausea, sore throat, teeth damage, dry scratchy eyes, awareness during the procedure, forgetfulness afterward, and many other smaller ones."
That does not take too long to say, but may not convey the gravity of the situation properly. This is all patient specific. If I feel like expounding on any of the risks to make sure that understanding has happened, here are some transitions I use depending on the patient and situation.
"Any time we give powerful medications, bad things are possible. They are rare, but like with all statistics, if they happen to you, you are the one that has to deal with it. The most common one is nausea. Do you get nauseous easily? Other problems can include..."
"Part of the consent process is to tell you about risks that can happen. There are some more minor ones, like nausea, a sore throat, teeth damage, or scratchy eyes. Then there are the big bad ones, like not breathing, heart or brain problems of many different kinds..."
"There is a long list of bad things that can happen, but they are rare. For your COPD I am going to be watching your breathing very well, as low oxygen levels can cause very bad things to happen. Other things I will be watching for are..."
"Did you eat any breakfast today? No? Good, we do not want bacon and eggs and stomach acid to come into your lungs. Then we might have to leave you on a ventilator in the ICU. Not letting you eat breakfast was not meant as torture, but as a way to minimize risks. Other risks of anesthesia include..."
"For your child we are going to be giving general anesthesia. That means he/she will be all the way asleep and we will be breathing for them. No parent really wants to hear about all of the bad things that can happen under anesthesia. So if you do not want to hear them all, I will just say that bad things are possible, and that I will be paying especially close attention to your child's breathing and oxygen levels."
"While you are sleeping I am going to put a breathing tube in to breathe for you, as anesthesia can stop your breathing. Do you have any loose or chipped teeth? Any crowns or implants, especially in the front that I should especially worry about? I haven't knocked any teeth out yet, and I do not want you to be the first. It is a soft rubber breathing tube, but if you bite down hard while waking up, there is a chance of tooth damage, and I do not pay for new teeth."
"We will have you take out your dentures as we do not pay for new ones if they are broken."
"After anesthesia it may seem that your mom/dad has taken a step back in their dementia or forgetfulness. Pre-existing forgetfulness is one of the bigger risk factors. If this happens, it can last for the rest of the day, a few days, or even weeks. There is still ongoing research into the exact causes, because it can happen with different types of anesthetics, like spinals, sedation, general, even nerve blocks. I will try and give them as few medications as necessary, but it still may occur."
