Summary
Patient-controlled analgesia (PCA) offers superior postoperative pain relief and patient satisfaction compared to conventional methods. While trends suggest reduced analgesic use and shorter hospital stays, further research is needed to confirm these benefits.
Area of Science:
- Anesthesiology and Pain Management
- Clinical Pharmacology
- Evidence-Based Medicine
Background:
- Postoperative pain management is crucial for patient recovery and satisfaction.
- Conventional analgesia often involves as-needed intramuscular dosing.
- Patient-controlled analgesia (PCA) offers an alternative approach to pain management.
Purpose of the Study:
- To compare the efficacy and outcomes of patient-controlled analgesia (PCA) versus conventional analgesia in postoperative patients.
- To analyze data from published comparative trials to determine the preferred method of pain control.
Main Methods:
- Meta-analysis of 15 randomized controlled trials.
- Inclusion of 787 adult patients undergoing various operative procedures.
- Comparison of PCA with conventional analgesia for postoperative pain control.
Main Results:
- PCA demonstrated greater analgesic efficacy (mean benefit 5.6/100, p=0.006).
- A significant preference for PCA was observed, with 42% higher patient satisfaction (p=0.02).
- No significant differences in side effects were found; trends suggested reduced analgesic use and shorter hospital stays with PCA.
Conclusions:
- Patient preference strongly favors PCA for postoperative pain management.
- PCA provides better pain relief without increasing side effects.
- Further studies are warranted to confirm the statistically significant impact of PCA on analgesic usage and hospital stay length.

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
