Post-Operative Nausea And Vomiting - Symptoms, Reasons And Treatment
Post-operative nausea and vomiting (PONV) can occur after surgery and anesthesia. The body's response to these interventions can lead to feelings of queasiness and vomiting in some patients. Several factors can contribute to PONV, including the type of surgery, individual sensitivity to anesthesia, and medications used during the procedure. The body's attempt to readjust and recover from the effects of anesthesia can also trigger nausea and vomiting.
It is essential for healthcare providers to monitor and manage PONV to ensure the patient's comfort and recovery. Understanding the potential causes of PONV can help healthcare professionals tailor interventions to prevent or minimize these symptoms post-surgery.
What Are the Symptoms of Post-Operative Nausea And Vomiting?
Symptoms may include feeling queasy, having an upset stomach, and a strong urge to vomit. These sensations can occur shortly after waking up from anesthesia or develop gradually. Nausea may be accompanied by sweating, dizziness, or an increased heart rate.
Vomiting can follow, leading to further discomfort. It is important to inform healthcare providers if experiencing these symptoms post-surgery to receive appropriate management and relief.

Inhalational anesthetics, opioid medications, and certain surgical maneuvers can contribute to PONV. Additionally, individual susceptibility, such as female gender, non-smoking status, and a history of motion sickness or PONV, can increase the risk. The stimulation of the brainstem and gastrointestinal tract post-surgery, as well as psychological factors like anxiety, also play a role in triggering PONV. Overall, a combination of these factors can lead to the unpleasant symptoms of nausea and vomiting following surgery.
Types Of Post-Operative Nausea And Vomiting
Post-operative nausea and vomiting (PONV) is a common complication after surgery. It can be classified into different types based on its causes and the timing of its occurrence:
- Early-Onset PONV: This occurs within the first few hours after surgery and is often due to anesthesia, pain medications (especially opioids), or the effects of the surgical procedure itself. It may also be related to the body’s response to being under anesthesia.
- Late-Onset PONV: This occurs more than 24 hours after surgery and can be caused by factors such as pain, medications, or underlying medical conditions. It may also result from the use of narcotics or certain other medications prescribed post-surgery.
- Acute PONV: This occurs within the first 24 hours after surgery and is typically managed by anti-nausea medications. The causes may include the anesthetic agents, surgical procedure, or dehydration.
- Delayed PONV: This type manifests more than 24 hours after the surgery, often associated with medications (like opioids) or complications such as gastrointestinal disturbances.
- Post-Discharge PONV: This occurs after a patient has been discharged from the hospital and can be linked to the lingering effects of anesthesia or medications taken during the post-operative recovery period.
Risk Factors
Post-operative nausea and vomiting (PONV) can occur after surgery and is influenced by various risk factors. Patient-specific factors like female gender, non-smoking status, history of motion sickness or PONV, and younger age are associated with a higher risk of experiencing PONV.
- Female gender: Women are at higher risk for post-operative nausea and vomiting compared to men due to hormonal influences.
- History of motion sickness: Individuals with a history of motion sickness are more likely to experience post-operative nausea and vomiting.
- Duration of surgery: Longer surgical procedures increase the likelihood of post-operative nausea and vomiting occurring.
- Non-smoking status: Non-smokers have a higher risk of post-operative nausea and vomiting compared to smokers following surgery.
- Opioid analgesics: The use of opioid medications for pain management post-surgery is a significant risk factor for nausea and vomiting.

Diagnosis of Post-Operative Nausea And Vomiting
Post-operative nausea and vomiting (PONV) is diagnosed based on a combination of patient history, physical examination, and specific diagnostic tests. The healthcare provider will inquire about the patient's medical history, including any previous episodes of PONV or motion sickness. A physical examination may be conducted to assess the patient's overall health and identify any potential underlying conditions that could contribute to PONV.
Diagnostic tests such as blood work or imaging studies may be ordered to rule out other possible causes of nausea and vomiting. Additionally, the healthcare provider may use scoring systems to assess the patient's risk for developing PONV based on various factors such as gender, age, and type of surgery performed.
Treatment for Post-Operative Nausea And Vomiting
Medications such as antiemetics, including serotonin antagonists, corticosteroids, and antihistamines, are commonly used to prevent and treat these symptoms. Non-pharmacological interventions like acupuncture, acupressure, and ginger supplements may also offer relief. In some cases, adjusting anesthesia techniques or providing intravenous fluids can help reduce the risk of post-operative nausea and vomiting.
It is essential for healthcare providers to individualize treatment based on the patient's risk factors, surgical procedure, and medical history to achieve optimal outcomes and improve patient comfort during the recovery period.
