Stop before your op
Why you should stop smoking before surgery and stop tips for pre-op smokers.
Stop before your op!
If you are waiting for an operation then it’s very important that you stop smoking as soon as possible. Smoking greatly increases the risk of complications during and after surgery. Some operations aren’t even an option for smokers.
- Smokers are far more likely to have anaesthesia-related complications.
- Smoking can delay your recovery and the wounds are slower to heal.
Smoking increases the risk of anaesthesia complications
If you smoke 10 cigarettes a day you have six times more risk of post-operative breathing problems. This risk increases the more you smoke and the longer you have smoked. There are several reasons for this:
Anaesthesia helps to reduce spasms and coughing during and after an operation. But because the tar in tobacco smoke constantly irritates the lungs, smokers need more anaesthesia to lessen these problems. This gives a higher risk of anaesthesia-related complications.
Smoking destroys the little hairs or cilia that help to clean out your lungs. The mucus in smokers’ lungs is contaminated with tar and other poisons in tobacco smoke. After anaesthesia it is very important for all patients to clear mucus out of the lungs. Even non-smokers are at risk of post-op pneumonia if the lungs don’t clear the mucus. But the risk for smokers is much greater as the lungs can’t clean themselves. The poisons in tobacco smoke build up and cause a higher risk of chest infections.
All patients go to the recovery room after an operation until they are considered stable enough to return to the ward. But smokers need a lot more time in the recovery room before they stabilise. All smokers are at risk. Light smokers spend as long recovering as heavy smokers so cutting down is not an option. After anaesthesia the blood is unable to supply enough oxygen to the body and most patients are given extra oxygen in the recovery room. Because the carbon monoxide in tobacco smoke robs the blood of oxygen then smokers need more oxygen therapy and for longer. Some smokers need oxygen even after they leave the recovery room.
Smokers have slower wound healing
Smokers have slower healing of wounds whether they are caused by surgery, injury or disease.
Healing is helped by plenty of oxygen in the blood reaching the wound. But nicotine in tobacco smoke makes the blood vessels tighten and this reduces the amount of blood reaching the wound. Then the carbon monoxide in smoke robs the blood of oxygen. The wound cannot heal as not only is there a reduced blood flow but also there is a lower level of oxygen in the blood.
Nicotine in tobacco smoke damages the production of red blood cells that carry essential healing chemicals to the scar tissue. Nicotine also makes blood platelets ‘sticky’. Platelets are a type of blood cell needed for clotting. This can lead to lots of small blood clots at the site of the wound. This reduces blood flow to the area and slows the healing process.
Examples of surgical risks for smokers
Slowing down the healing of wounds is a big problem for smokers having plastic or reconstructive surgery. This type of surgery usually involves the transfer of flaps of skin from one part of the body to another.
To survive, the skin needs a healthy blood supply and lots of oxygen. Because smokers have a reduced blood flow, the skin being transferred has a much lower chance of survival. Smokers have about 12.5 times greater risk of plastic surgery not being successful.
Reduced blood flow is a great concern for hand surgery because there are so many tiny blood vessels in the hands. Smoking a single cigarette can reduce the blood flow to the hand by 40% for up to an hour. This would cause a severe shortage of oxygen needed to aid healing.
Smokers’ bones are slower to grow and repair than non-smokers’ bones. When smokers need surgery to fuse the vertebrae in the back they are 3 to 4 times more likely to have problems. The bones must build new bone cells. Non-smokers’ bones can grow 1cm every 2 months. Smokers can take on average 3 months to grow the same amount of bone.
The sooner you stop before your op, the better
Stopping smoking at least 8 weeks before surgery reduces your risk of a range of complications. If you smoke, you have a 1 in 3 risk of post-operative breathing problems. This can be reduced to 1 in 10 if you stop 8 weeks before your op.
Smoke-free days can help
Unfortunately, not everyone knows they are going to have surgery until they actually need it. Stopping 72 or 48 hours before an operation can decrease some of the risks. Carbon monoxide and nicotine are cleared from the body in a matter of days. This can help to improve healing and recovery.
