A Model of Postanesthesia Care Unit-Based Acute Pain Service

Highlights in postoperative pain treatment

Acute pain is a symptom that originates from actual ongoing or impending tissue damage. Pain is an individual subjective experience and varies markedly among individuals. For this reason, patient involvement is essential, with the most reliable indicator of severity being patient self-report. The main objective of postoperative pain management is the achievement of fast rehabilitation, recovery of all normal functions and reduction of postoperative morbidity. Sufficient evidence supports the hypothesis that effective analgesia modifies many of the adverse sequelae that accompany acute pain and assists in recovery. Nevertheless, despite the availability of drugs and techniques for its effective management, postoperative pain remains undertreated. It is now accepted that the solution to the problem of inadequate pain relief lies not only in the development of new analgesic drugs or technologies but also in the development of an appropriate organization to utilize existing expertise. Methods used to control postoperative pain are numerous; this review focuses on pharmacological and anesthetic methods.

The evolution and practice of acute pain medicine

BACKGROUND

In recent years, the field of acute pain medicine (APM) has witnessed a surge in its development, and pain has begun to be recognized not merely as a symptom, but as an actual disease process. This development warrants increased education of residents both in the performance of regional anesthesia as well as in the disease course of acute pain and the biopsychosocial mechanisms that define interindividual variability.

REVIEW SUMMARY

We reviewed the organization and function of the modern APM program. Following a discussion of the nomenclature of acute pain-related practices, we discuss the historical evolution and modern role of APM teams, including the use of traditional, as well as complementary and alternative, therapies for treating acute pain. Staffing and equipment requirements are also evaluated, in addition to the training requirements for achieving expertise in APM. Lastly, we briefly explore future considerations related to the essential role and development of APM.

CONCLUSION

The scope and practice of APM must be expanded to include pre-pain/pre-intervention risk stratification and extended through the phase of subacute pain.

A prospective audit of postoperative pain control in pediatric patients

Pain is a subjective experience that is affected by physical, emotional, and psychological factors, and reliable assessment of pain can be a challenge in the pediatric population. A quality improvement project was conducted at one Canadian health care facility to examine the effectiveness of the postoperative pain management strategy for children admitted to the postanesthesia care unit (PACU). Effective control of postoperative pain involves several preventive strategies that include preoperative analgesia, appropriate use of intraoperative analgesic techniques, and identification of children at risk for significant postoperative pain. Successful implementation of these techniques requires a multidisciplinary team approach involving the patient, the PACU nurses, the anesthesia care provider, and other surgical team members.
