Short-term Outcomes in Pediatric Patients Managed with Peripheral Nerve Blockade for Arthroscopic Anterior Cruciate Ligament Reconstruction and/or Meniscus Surgeries

[Research progress on early postoperative pain management strategies after arthroscopic anterior cruciate ligament reconstruction]

Objective

To summarize the early postoperative pain management strategies for anterior cruciate ligament reconstruction (ACLR), and to select a reasonable and effective pain management plan to promote functional rehabilitation after ACLR.

Methods

The literature about the early postoperative pain management strategies of ACLR both domestically and internationally in recent years was extensiverly reviewed, and the effects of improving postoperative pain were reviewed.

Results

Currently, physical therapy and oral medication have advantages such as economy and simplicity, but the effect of improving postoperative pain is not satisfactory, often requires a combination of intravenous injection or intravenous pump, which is also a common way to relieve pain. However, in order to meet the analgesic needs of patients, the amount of analgesic drugs used is often large, which increases the incidence of various adverse reactions. Local infiltration analgesia (LIA), including periarticular or intra-articular injection of drugs, can significantly improve the early postoperative pain of ACLR, and achieve similar postoperative effectiveness as nerve block. LIA can be used as an analgesic technique instead of nerve block, and avoid the corresponding weakness of innervated muscles caused by nerve block, which increases the risk of postoperative falls. Many studies have confirmed that LIA can alleviate postoperative early pain in ACLR, especially the analgesic effects of periarticular injection are more satisfactory. It can also avoid the risk of cartilage damage caused by intra-articular injection. However, the postoperative analgesic effect and timeliness still need to be improved. It is possible to consider combining multimodal mixed drug LIA (combined with intra-articular and periarticular) with other pain intervention methods to exert a synergistic effect, in order to avoid the side effects and risks brought by single drugs or single administration route. LIA is expected to become one of the most common methods for relieving postoperative early pain in ACLR.

Conclusion

Early pain after arthroscopic ACLR still affects the further functional activities of patients, and all kinds of analgesic methods can achieve certain effectiveness, but there is no unified standard at present, and the advantages and disadvantages of various analgesic methods need further research.

Ambulatory Pain Management in the Pediatric Patient Population

PURPOSE OF REVIEW

Outpatient surgery in the pediatric population has become increasingly common. However, many patients still experience moderate to severe postoperative pain. A poor understanding of the extent of pain after pediatric ambulatory surgery and the lack of randomized control studies of pain management of the outpatient necessitate this review of scientific evidence and multimodal analgesia.

RECENT FINDINGS

A multimodal approach to pain management should be applied to the ambulatory setting to decrease postoperative pain. These include non-pharmacological techniques, multimodal pharmacologics, and neuraxial and peripheral nerve blocks. Postoperative pain management in pediatric ambulatory surgical patients remains suboptimal at most centers due to limited evidence-based approach to postoperative pain control. Pediatric ambulatory pain management requires a multipronged approach to address this inadequacy.

Decreased Prescribing of Postoperative Opioids in Pediatric ACL Reconstruction: Treatment Trends at a Single Center

BACKGROUND

Anterior cruciate ligament (ACL) injury is common in the pediatric population. Pain control after ACL reconstruction (ACLR) presents a unique challenge due to age and early rehabilitation needs. Pain management practices are believed to have evolved in recent years to limit unnecessary exposure to risks associated with opioid use in this vulnerable population.

PURPOSE

To describe trends in postoperative opioid prescribing and assess factors including obtaining consent for opioid prescribing for minors that may have mitigated excessive prescription of opioids.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

This is a retrospective review of a consecutive series of pediatric patients (<18 years) undergoing primary ACLR within an urban academic hospital system over a 5-year period (2014-2018). The study period included the gradual introduction of preoperative consenting for opioid use in minors as mandated by state law in 2016. Patient characteristics, surgical details, presence of a signed consent form to prescribe opioid medications, prescribed postoperative medications, prescriber, and indicators of inadequate pain control were collected. Univariate and multivariate analyses were performed to determine factors associated with reduced postoperative opioid prescribing.

RESULTS

This study included 687 patients with a mean age of 15.1 ± 1.9 years, with less than one-third of patients having preoperative consent forms to prescribe opioid medications. Postoperative prescribing trends demonstrated a decline in the number of opioid doses provided and increased utilization of nonopioid medications. Patients who received preoperative opioid counseling and signed a consent form were prescribed fewer opioids and had a smaller number of unscheduled contacts for poorly controlled pain. Univariate analyses identified multiple predictors of the number of opioid doses prescribed postoperatively. Obtaining preoperative consent to prescribe opioids and ambulatory surgery center location were found to be independent predictors of prescribed doses in the multivariate analysis.

CONCLUSION

The quantity of opioid medication prescribed for pain management after pediatric ACLR at our institution has declined in recent years. This appears to be, in part, related to state-mandated preoperative counseling about opioid use, signing of a consent form by the parent(s) or guardian(s) to prescribe opioids to minors, and encouragement toward the use of nonopioid medications when possible. Preoperative opioid use discussions in the pediatric population may be useful in reducing opioid overprescription and utilization in this population.
