One of the primary advantages of PCEA is the ability to provide continuous pain relief with the option of patient-controlled boluses. This can lead to more consistent pain management compared to traditional methods. Other advantages include: - Improved pain control: Patients can manage their pain more effectively by administering medication when needed. - Reduced need for systemic opioids: This can decrease the risk of opioid-related side effects. - Increased patient satisfaction: The autonomy to control pain relief can improve overall patient experience and comfort.
