You may not be able to wake up for two to four hours after being sedated. During this period, you will continue to breathe through the breathing tube with the assistance of a ventilator, which is a machine that moves air into and out of your lungs, basically "breathing" for you. After about four hours, most patients can be woken up.
Most patients are able to walk around within an hour of waking up and return to normal activities within days. However, more vigorous activity should be avoided for several weeks following open-heart surgery because of the risk of further clogging arteries due to the extra blood flow to major organs such as the brain and kidneys that occurs during exercise.
It is important to remember that you were given a number of medications after open heart surgery, including:
Antibiotics - These prevent infections from developing after open heart surgery. Most often, antibiotics are prescribed following open heart surgery indefinitely until postoperative tests show there no longer is a threat of infection.
Anti-arrhythmics - These help control abnormal heart rhythms that can occur after open heart surgery. Anti-arrhythmic drugs can be used both before and after open heart surgery.
Beta blockers - These reduce the workload of the heart by slowing down its response to stress.
Following Surgery If you were sedated or under general anesthesia, don't expect to be completely awake immediately away; it may take some time, and you may nod off for a while. It normally takes 45 minutes to an hour to fully recover from general anesthesia. You should be given medication to help you sleep if needed after your surgery.
You might be in this unit for one to three days. A prolonged stay does not imply that your CABG operation was a failure. It might signify that it is taking longer for your anaesthetic to wear off or for fluid in your chest to drain. You may experience a variety of feelings as you awaken. These include confusion, depression, anxiety and anger.
Many people are able to go home on the same day as their operation. Others will need more time to recover before they can leave the hospital. Everyone's situation is different so it's best to speak with members of your care team about how you feel after surgery.
If you are having problems breathing or feeling pain in your chest, let someone know immediately.
Do not drive until you have been released from the hospital. If you take medications like aspirin, blood thinners or warfarin (Coumadin), ask your doctor what actions to take if you must start them again after open heart surgery.
People who have had open heart surgery require careful monitoring by doctors after they leave the hospital. They are at risk for similar problems that led to their operation. For example, someone who has had a valve replacement might suffer serious bleeding if they bruise themselves. They should also avoid tasks that could cause them to lift heavy objects or exercise strenuously until they have healed.
Open heart surgery is a very important part of treating heart disease.
If you've had a local anaesthetic, it should take around an hour to wear off fully. Sedation can take up to 24 hours to wear off fully, and it is suggested that you do not drive or handle heavy machinery, so you should plan alternate transportation home. If you're not tired when you go to sleep, the procedure may have been too much for you to handle.
Generally, people start to feel better within 30 minutes to 1 hour after the procedure. The doctor may have told you to drink plenty of water during your appointment to remove any residue in your stomach from the medicine used as sedation. You should also be drinking enough water overall to stay healthy.
Some people report feeling more tired than usual for a few days after their endoscopy. This is normal and most patients go back to their regular routines within a day or two.
Although it is uncommon, people who have been given general anesthesia may occasionally awaken during surgery. According to Dr. Lee A., this occurs in 1 to 2 out of 1,000 surgeries. People tend to wake up at the start of the procedure and then sleep through the rest of it. Usually they report that they feel pain and are worried about what is happening to them.
Why do we need open heart surgery? In most cases, open heart surgery is needed because other methods have failed to repair an abnormal heart valve. The surgery allows the surgeon to replace the valve, repair certain defects on the surface of the heart (such as a hole or area of thinness) or perform other procedures to improve blood flow through the heart.
What are the risks involved with open heart surgery? The risk of death during open heart surgery is low, but things can go wrong even with very small wounds. Because open heart surgery requires opening the chest cavity, patients are at risk for developing complications such as infection, stroke or lung injury.
How do I prepare for open heart surgery? In order to reduce your risk of bleeding during surgery, you will be given drugs to make your body more resistant to blood loss and reduce your platelet count. You will also be asked to stop taking medications that cause your stomach or intestines to make ulcers.
If general anesthesia is utilized, the anesthesiologist will begin the process of converting you from a normal waking state to a drowsy condition of anesthesia. This is known as induction, and it is often accomplished by either injecting drugs through an IV or breathing gases through a mask. The anesthesiologist may also be able to achieve this same result with only local anesthesia if necessary.
Once you are under the influence of anesthesia, doctors will use various methods to try and wake you up without causing further damage to your brain. These methods include oxygenation via mask or cannula, coughing, mechanical stimulation (such as shaking), and finally injection of a drug called atropine. Atropine is used because it works on all types of anesthesia, it does not cause other problems when administered during surgery, and it can always be reversed if needed.
Anesthesiologists generally attempt to keep you asleep during surgery so that you do not feel anything important is happening. They may also want to avoid having you wake up too soon after they stop administering drugs, since this might cause you to lose muscle tone and possibly fall out of bed unassisted.
After surgery is complete and you have recovered from any associated injuries, your anesthesiologist will again attempt to wake you up for removal from the anesthesia machine. This is usually done by increasing the amount of oxygen flowing into your blood stream via a cannula or mask.
