Inhaled peppermint oil for postop nausea in patients undergoing cardiac surgery

Area of Science:

• Anesthesiology
• Symptom Management
• Complementary and Alternative Medicine

Background:

• Postoperative nausea is a prevalent and distressing complication following surgery.
• It can lead to adverse outcomes such as pain, wound dehiscence, and aspiration.
• Current antiemetic drugs often cause side effects like drowsiness and dysrhythmias, limiting patient mobility.

Purpose of the Study:

• To investigate the efficacy of peppermint oil inhalation for managing postoperative nausea.
• To evaluate peppermint oil as a potential first-line treatment in cardiac surgery patients.

Main Methods:

• A study involved 123 patients undergoing cardiac surgery; 34 experiencing nausea were offered peppermint oil nasal inhalers.
• Informed consent was obtained from all participants.
• Nausea levels were rated on a 0-5 scale before and after intervention.

Main Results:

• The average nausea rating decreased from 3.29 (SD, 1.0) to 1.44 (SD, 1.3) within two minutes of using peppermint oil.
• This reduction in nausea was statistically significant (P = 0.000).

Conclusions:

• Peppermint oil inhalation is a safe and effective first-line treatment for postoperative nausea in cardiac surgery patients.
• It presents a viable alternative to pharmacologic antiemetics with fewer side effects.
• Further research may explore its application in other surgical populations.
