Inhaler Medications Around Surgery: What to Expect
Inhalers used for asthma and COPD (chronic obstructive pulmonary disease) require special attention around surgery. General anesthesia and airway manipulation can trigger bronchospasm in patients with underlying lung conditions. This guide explains which inhalers to continue, which to adjust, and how to manage your respiratory medications through the surgical period.
Types of Inhalers Used for Respiratory Conditions
Short-acting beta-agonists (SABAs): Albuterol (ProAir, Ventolin) are rescue inhalers. They open airways within minutes and last 4 to 6 hours. Use as needed and as instructed before surgery.
Long-acting beta-agonists (LABAs): Salmeterol and formoterol are used with inhaled corticosteroids for daily maintenance. They are not rescue medications.
Inhaled corticosteroids (ICS): Fluticasone (Flovent) and budesonide (Pulmicort) reduce airway inflammation with daily use. They do not provide immediate relief.
Combination inhalers: Fluticasone/Salmeterol (Advair) and Budesonide/Formoterol (Symbicort) provide both long-acting bronchodilation and anti-inflammatory effects in one device.
Anticholinergic inhalers: Tiotropium (Spiriva) and ipratropium (Atrovent) reduce mucus production and airway constriction. Used primarily for COPD.
Long-acting muscarinic antagonists (LAMAs): Umeclidinium (Incruse) and aclidinium (Tudorza) are once-daily anticholinergic options for COPD maintenance.
Continuing Inhalers Before and on Surgery Day
Continue all maintenance inhalers (ICS, LABA, combination, anticholinergics) as scheduled up to and including the morning of surgery.
Use your rescue inhaler (albuterol) as needed and take your scheduled morning dose on surgery day.
Bring all inhalers to the hospital or surgical center. Your anesthesiologist needs to review them before the procedure.
Tell your anesthesiologist about all inhalers at the preoperative visit. Poor asthma or COPD control before surgery significantly increases the risk of bronchospasm during intubation (placement of a breathing tube).
If your asthma has been poorly controlled in the weeks before surgery, notify your surgeon. The procedure may need to be rescheduled until lung function improves.
Patients with asthma or COPD may receive a nebulized bronchodilator treatment before surgery as part of preoperative preparation, especially if they have active symptoms.
After Surgery Respiratory Care
Resume all inhaler medications as soon as you are able to breathe and swallow normally after surgery.
Deep breathing exercises and incentive spirometry (a handheld device that guides slow, deep breaths) are prescribed after many surgeries to prevent pneumonia and mucus buildup in the lungs.
Post-surgical pain can make breathing feel difficult. Consistent inhaler use and effective pain management together protect lung function.
After chest or abdominal surgery, using a metered-dose inhaler (MDI) may be uncomfortable due to incision pain. Ask your care team about a spacer device or temporary nebulizer.
Avoid cigarette smoke and secondhand smoke during recovery. Smoke exposure worsens airway inflammation and slows healing.
Warning Signs Requiring Immediate Attention
Wheezing, chest tightness, or shortness of breath that does not improve within 15 to 20 minutes of using your rescue inhaler.
Breathing rate greater than 25 breaths per minute at rest.
Inability to speak in full sentences due to breathlessness.
Blue or grayish color around the lips or fingernails, indicating low oxygen levels. Call emergency services immediately.
Fever over 101.5 degrees F combined with a productive cough and worsening shortness of breath, which may indicate pneumonia.
Frequently asked
Questions patients ask.
Should I take my inhaler the morning of surgery?
Yes. Continue all maintenance inhalers as scheduled on the morning of surgery. Use your rescue inhaler if your provider instructed a preoperative dose. Confirm with your surgical team if you have specific questions about timing.
What if I have an asthma attack during surgery?
Your anesthesiologist monitors your airways throughout the procedure. Bronchospasm during surgery is treated immediately with bronchodilators delivered through the breathing circuit. Disclosing your respiratory conditions beforehand allows the team to prepare the correct medications and techniques in advance.
Can I use my nebulizer instead of my inhaler after surgery?
Yes. A nebulizer delivers the same medication as a mist, which may be easier to inhale when using a handheld inhaler is uncomfortable after chest or abdominal surgery. Ask your care team to arrange this if needed.
Do inhaled corticosteroids increase infection risk after surgery?
At typical maintenance doses, inhaled corticosteroids do not meaningfully suppress the immune system and do not significantly increase surgical infection risk. High-dose oral or intravenous steroids carry more risk. Continue your inhaled corticosteroid as prescribed.
