Is It Safe to Have Surgery With COPD?

Surgery with COPD is feasible and happens routinely, but it does carry a meaningfully higher risk of complications than surgery in people without the disease. A large national database analysis found that COPD independently raises the odds of postoperative pneumonia, respiratory failure, heart attack, cardiac arrest, sepsis, and kidney problems.¹ That sounds alarming, but whether those risks actually apply to you depends on the severity of your COPD, the kind of surgery planned, and what you and your medical team do in the weeks before the operation.

How COPD Raises Surgical Risk

The core problem is straightforward: COPD leaves you with less breathing reserve. Healthy lungs can tolerate the temporary insults of anesthesia, pain medication that slows breathing, and the inflammatory response that follows surgery. Lungs already compromised by COPD have a smaller margin of error. When something goes wrong with breathing after an operation, COPD patients are less able to compensate, and a minor setback can cascade into a serious one.

Prospective studies tracking COPD patients through surgery put the rate of postoperative lung complications at roughly one in three. One observational study of 100 COPD patients found that 38% developed at least one pulmonary complication, including collapsed lung segments, bronchospasm, pneumonia, low oxygen levels, and respiratory failure requiring ventilator support.² A separate retrospective study of 107 COPD patients undergoing abdominal surgery found that the most common cardiac event was an irregular heart rhythm, occurring in about 16% of patients, while pneumonia, persistently low oxygen, and prolonged time on a ventilator each affected roughly 8 to 9%.³

The risks extend beyond the lungs. The national database study noted that COPD was independently linked to higher rates of needing a return trip to the operating room and developing kidney problems after surgery.¹ These are systemic consequences of the body’s reduced ability to handle surgical stress when lung function is already impaired.

Why the Type of Surgery Matters More Than You Might Think

One of the most overlooked facts about surgical risk in COPD is that what kind of surgery you are having matters enormously, sometimes more than the COPD itself. Procedures in the chest and upper abdomen carry the highest pulmonary complication rates because they directly affect the muscles used for breathing. Operations on the lower abdomen, limbs, or body surface pose considerably less respiratory risk. The duration of surgery and whether a breathing tube is placed also weigh heavily in the equation.

Laparoscopic (keyhole) surgery generally causes less respiratory disruption than open surgery, but it is not risk-free for COPD patients. The gas used to inflate the abdomen during laparoscopy pushes up on the diaphragm and temporarily reduces lung compliance. In one study, COPD patients showed significantly reduced lung flexibility during certain body positions required for laparoscopic procedures, particularly when tilted head-down.⁴ Despite this, the smaller incisions and shorter recovery time of laparoscopic surgery still make it the preferred approach when available.

How COPD Severity Changes the Picture

Not all COPD is equal when it comes to surgical risk. Someone with mild, well-controlled COPD faces a very different set of odds than someone with severe disease and frequent flare-ups. Doctors use classification systems to gauge this, and the most relevant ones look at both lung function numbers and how often symptoms flare up.

A study that grouped COPD patients by severity found that those in the higher-risk categories (characterized by worse airflow limitation and more frequent exacerbations) had roughly four times the odds of postoperative complications compared to lower-risk patients.⁵ The higher-risk group also had significantly more postoperative infections and wound complications. Interestingly, the higher-risk group in that study did not show a statistically significant increase in lung-specific complications compared to the lower-risk group, which suggests that the surgical stress of COPD is not limited to the lungs alone.⁵

Formal risk-scoring tools can sharpen these predictions further. The ARISCAT score, which accounts for factors like age, oxygen levels, the surgical site, and whether the surgery is an emergency, has been shown to be a strong predictor of pulmonary complications. One study found that patients with high-risk ARISCAT scores had nearly five times the rate of postoperative lung problems compared to those with intermediate or low-risk scores.⁶ Lower lung function as measured by how much air you can forcefully exhale in one second was also independently linked to worse outcomes.⁷

The practical takeaway is that if your COPD is mild and stable, your surgical risk is elevated but manageable. If your COPD is severe with frequent flare-ups, surgery is still possible, but the stakes are higher and the preparation needs to be more aggressive.

Preparing Your Lungs Before Surgery

The weeks before a planned operation are among the most important for COPD patients, because several interventions can meaningfully reduce the risk of complications. This is one area where the evidence is genuinely encouraging.

Bronchodilator Therapy

If you are not already on inhaled bronchodilators, starting them before surgery can help. A retrospective study of COPD patients undergoing lung surgery found that short-term preoperative inhalation therapy, particularly using long-acting bronchodilators, improved respiratory function heading into the operation.⁸ When bronchodilators were continued through the recovery period, the decline in lung function that normally follows surgery was cushioned. One large study found that perioperative bronchodilator use reduced the drop in forced air output at one, four, and twelve months after surgery, and the benefit held up across subgroups regardless of age, sex, smoking status, or the extent of the operation.⁹

Smoking Cessation

If you are still smoking, quitting before surgery is one of the single most effective things you can do. Smoking compounds every COPD-related surgical risk by adding airway irritation, increased mucus production, and carbon monoxide exposure that reduces oxygen delivery. Stopping even in the weeks before an operation can begin to reduce these risks, and surgeons are encouraged to screen for smoking status and offer cessation support when scheduling procedures.¹⁰ The longer the smoke-free interval before surgery, the better, but even a few weeks helps.

Breathing Exercises and Muscle Training

Preoperative inspiratory muscle training, which involves structured exercises that strengthen the muscles you use to breathe in, has some of the strongest evidence behind it. A Cochrane systematic review found that this training was associated with roughly halving the risk of both collapsed lung segments and pneumonia after cardiac and major abdominal surgery.¹¹ A randomized trial in high-risk patients undergoing heart bypass surgery found that the group trained before surgery had an 18% complication rate versus 35% in the usual-care group, and pneumonia specifically dropped from about 16% to roughly 7%. Hospital stays were about a day shorter on average.¹²

A more recent randomized trial in heart valve surgery patients confirmed these findings, showing that preoperative breathing muscle training improved lung function measurements before surgery and reduced the drop in those measurements afterward. The trained group experienced fewer pulmonary complications than both a sham-training group and a control group.¹³ These exercises typically involve a handheld device that provides resistance as you breathe in, used for a few weeks leading up to the surgery. It is low-cost, safe, and one of the few interventions where the effect size is large enough to feel confident recommending it to nearly any high-risk patient.

Choosing the Right Anesthesia

The type of anesthesia used can meaningfully affect outcomes for COPD patients. General anesthesia, which requires a breathing tube and a ventilator, puts more stress on already-compromised lungs. Regional anesthesia, which numbs only the area being operated on while you remain conscious or lightly sedated, avoids many of those stresses.

A large matched study comparing the two approaches in COPD patients found that general anesthesia was associated with higher rates of postoperative pneumonia (about 3.3% versus 2.3%), prolonged ventilator dependence (2.1% versus 0.9%), and unplanned intubation after surgery (2.6% versus 1.8%). Overall complications ran about 15% with general anesthesia versus about 13% with regional. Thirty-day death rates, however, were similar between the two groups.¹⁴

The advantage of regional anesthesia appears even more pronounced in specific settings. A study of COPD patients undergoing hip surgery for fractures found that those given spinal anesthesia had lower 30-day death rates (about 6% versus 8%), fewer unplanned intubations, and were more likely to be discharged home rather than to a care facility.¹⁵ General anesthesia was identified as an independent risk factor for death and unplanned intubation in that population.

Not every surgery can be done under regional anesthesia, of course. Chest and abdominal operations often require general anesthesia, and in those cases the anesthesiologist focuses on ventilator settings that accommodate the stiff, over-inflated lungs characteristic of COPD. But when there is a choice, and the surgery lends itself to a regional approach, the evidence favors avoiding general anesthesia in COPD patients. Regional techniques are increasingly being used even for procedures that were historically done under general anesthesia, including some upper-limb orthopedic and abdominal operations.¹⁶

What Happens After the Operation

Postoperative care for COPD patients extends well beyond standard recovery protocols. One particular risk is a COPD exacerbation, a flare-up of worsening breathlessness, coughing, and mucus production triggered by the stress of surgery. A study of over a thousand COPD patients who underwent lung surgery found that postoperative exacerbations occurred frequently, and more than half of those who had a flare-up went on to develop further respiratory complications. Severity of COPD was a key predictor of whether a flare-up would happen.¹⁷

For patients who needed a ventilator during surgery, the transition off the ventilator is a critical moment. Prophylactic use of non-invasive ventilation (a face or nasal mask that delivers pressurized air) immediately after the breathing tube is removed can dramatically reduce the risk of needing re-intubation, but the benefit appears limited to patients whose carbon dioxide levels are elevated. In patients with high carbon dioxide levels, prophylactic non-invasive ventilation reduced re-intubation rates from 30% to 4% within 72 hours, and hospital death rates dropped from 40% to 18%. In patients with normal carbon dioxide levels, the same intervention made no measurable difference.¹⁸ This is a good example of how postoperative interventions need to be targeted rather than applied across the board.

Delirium and Other Non-Pulmonary Complications

Surgical risk for COPD patients is not limited to the lungs. Delirium, a sudden state of confusion and disorientation, is a recognized problem in older COPD patients, especially those who require mechanical ventilation after surgery or during a respiratory crisis. A prospective study found that several factors independently predicted delirium in elderly COPD patients on ventilators, including advanced age, low body weight, high blood pressure, illness severity scores, pain levels, sedation use, and low blood oxygen.¹⁹ Delirium extends hospital stays, increases the risk of further complications, and can be distressing for both patients and families. Minimizing sedation and maintaining adequate oxygen levels are key strategies for reducing this risk.

Heart-related complications also deserve attention. COPD frequently coexists with cardiovascular disease, and some patients develop elevated pressures in the blood vessels of the lungs, a condition that adds its own layer of surgical risk. The American Heart Association has issued guidance recommending that patients with this combination undergo a structured process of identifying the type of elevated lung pressures, assessing risk before surgery, optimizing treatment beforehand, managing pressures during the operation, and monitoring recovery afterward.²⁰ If your COPD comes with heart problems, expect your surgical team to coordinate closely with cardiology.

When Surgery Can Actually Help COPD

Most discussions of COPD and surgery focus on the risks that COPD adds to an unrelated operation. But some surgeries directly benefit the lungs. Bariatric surgery in obese COPD patients is a striking example. Excess weight compresses the lungs, and carrying it chronically worsens breathing function and increases the frequency of COPD flare-ups. A study following obese COPD patients through bariatric surgery found that while about 28% had emergency visits or hospitalizations for COPD flare-ups in the year before surgery, that rate dropped to 12% in the year after, and stayed low at 13% in the second year.²¹ The reduction was roughly 65%, a substantial and lasting improvement.

Lung volume reduction surgery, which removes the most damaged portions of emphysematous lung tissue to allow the remaining healthier tissue to function better, is another procedure where the surgery itself targets the COPD. These operations carry their own risks, but in carefully selected patients they can improve breathing capacity, exercise tolerance, and quality of life. The point is that the question “is it safe to have surgery with COPD” sometimes has an answer that depends on whether the surgery is fighting the disease or just coexisting with it.

Emergency Versus Elective Surgery

Everything discussed so far assumes you have time to prepare. Emergency surgery dramatically changes the calculus. There is no opportunity for weeks of breathing exercises, bronchodilator optimization, or smoking cessation. The surgical team cannot always choose the least risky anesthetic approach. Risk-scoring tools that rely on preoperative testing may not be fully available. Emergency status is itself a risk factor built into prediction scores like the ARISCAT.⁷

This does not mean emergency surgery should be avoided when it is needed. A ruptured appendix or a broken hip will not wait for lung optimization. But it does mean that if you have COPD and a condition that will eventually need surgical repair, there is a real advantage to scheduling it electively while you are stable rather than waiting until it becomes urgent. If your surgeon offers to schedule a procedure and you are tempted to delay indefinitely out of fear of anesthesia, the math may not favor waiting. Your COPD is unlikely to improve over time, and an eventual emergency operation carries higher risk than a well-prepared elective one.

What to Ask Your Surgical Team

If you have COPD and are facing surgery, a few specific conversations with your doctors can make a real difference in how things go:

Severity assessment: Ask where your COPD falls on a severity scale and what your recent lung function numbers look like. These directly inform how much extra risk you carry.
Anesthesia options: Ask whether regional anesthesia is feasible for your procedure. If general anesthesia is required, ask what ventilator strategies will be used to protect your lungs.
Prehabilitation plan: Ask about starting inspiratory muscle training and optimizing your inhaler regimen in the weeks before surgery. If you smoke, ask for cessation support now, not the week before the operation.
Postoperative plan: Ask what monitoring will be in place after surgery, whether non-invasive ventilation will be available, and what the plan is if you experience a COPD flare-up during recovery.
Comorbidities: If you have heart disease, elevated lung pressures, or sleep apnea alongside your COPD, make sure every specialist involved is communicating with the surgical and anesthesia teams.

COPD does not make surgery impossible, but it does make preparation non-negotiable. The patients who do best are the ones whose teams know about the COPD, take it seriously, and build a plan around it rather than treating it as an afterthought.
