Which medications are contraindicated during labor for a patient with asthma due to potential respiratory depression and bronchospasm?

• A. Morphine and Demerol
• B. Epidural analgesia
• C. Albuterol
• D. Lidocaine

Answer: (A)

When a patient with asthma is in labor, pain management choices should avoid anything that can worsen airway reactivity or depress breathing. Opioid analgesics such as morphine and meperidine can cause significant respiratory depression and trigger histamine release, which can provoke bronchospasm in a person with asthma. This combination—reduced respiratory drive plus potential airway constriction—raises the risk of hypoxemia for both mother and baby, so these opioids are avoided in this context. Other options described are safer in this scenario. Epidural analgesia provides effective pain relief with minimal systemic opioid exposure, reducing the chance of respiratory compromise. Albuterol is a bronchodilator and helps prevent or treat bronchospasm, which is protective for an asthmatic patient. Lidocaine, used as a local or regional anesthetic, does not carry the same risk of bronchospasm or respiratory depression.
