Patient-controlled modalities for acute postoperative pain management

Area of Science:

• Anesthesiology
• Pharmacology
• Pain Management

Background:

• Inadequate pain relief remains a significant healthcare challenge despite numerous clinical practice guidelines.
• Patient-controlled analgesia (PCA) offers a solution for acute postoperative pain.
• Current PCA modalities include intravenous (IV) PCA, epidural (PCEA), and oral PCA.

Purpose of the Study:

• To review existing patient-controlled analgesia (PCA) modalities for acute postoperative pain.
• To discuss novel and developing PCA systems.
• To highlight advancements in pain management technology.

Main Methods:

• Literature review of published clinical practice guidelines and research on PCA.
• Analysis of current intravenous (IV) PCA, epidural (PCEA), and oral PCA systems.
• Discussion of emerging noninvasive PCA technologies like transdermal and intranasal systems.

Main Results:

• Intravenous (IV) PCA is the standard of care but has limitations.
• Noninvasive PCA systems, such as fentanyl hydrochloride patient-controlled transdermal system (PCTS) and patient-controlled intranasal analgesia (PCINA), are under development.
• These new systems aim to overcome limitations of existing PCA methods.

Conclusions:

• Patient-controlled analgesia (PCA) remains crucial for managing acute postoperative pain.
• Ongoing development of noninvasive PCA technologies promises improved patient outcomes and experiences.
• Further research into novel PCA delivery systems is warranted to address unmet needs in pain management.
