Opioid Use, Perioperative Risks, and Associated Postoperative Complications in Foot and Ankle Surgery

Preoperative Opioid Use Predicts Poorer Outcomes of Total Ankle Arthroplasty and Hindfoot Fusions

BACKGROUND

This study aimed to determine the impact of preoperative opioid use on outcomes of patients undergoing ankle or hindfoot arthrodesis, or total ankle arthroplasty (TAA).

METHODS

We conducted a retrospective review of 190 patients undergoing an ankle or hindfoot arthrodesis (n=122) or TAA (n=68) between December 2015 and September 2020 with a single fellowship-trained orthopaedic foot and ankle surgeon at an academic medical center. Data collected included demographics, medical comorbidities, treatment history, complications and reoperation rates, patient-reported outcome measures (PROMs) (eg, Foot and Ankle Outcome Score [FAOS]), and opioid use.

RESULTS

Patients with preoperative opioid use were more likely to continue usage at 90 (r = 0.931, P < .001) and 180 (r = 0.940, P < .001) days postoperatively. For the entire cohort, complication and reoperation rates were 48.9% and 13.2%, respectively. While preoperative opioid use groups did not differ in the overall complication rate, users had significantly more infections (user = 12.5%, nonuser = 3.3%; P = .036) and reoperations (user = 22.5%, nonuser = 10.7%; P = .049). When analyzing postoperative opioid prescriptions, there were many significant correlations with preoperative PROMs, mainly FAOS, such that increased postoperative opioid use was associated with worse subjective outcomes.

CONCLUSION

Preoperative opioid users are more likely to continue postoperative opioid use, experience infections, and undergo reoperations.

A standardized anesthetic/analgetic regimen compared to standard anesthetic/analgetic regimen for patients with high-risk factors undergoing open lumbar spine surgery: a prospective comparative single-center study

The objective of the study is to improve the results of patients undergoing lumbar spine surgery who are at high risk for anesthesia and/or surgical complications. Two independent groups were compared: the study group (SG, n = 40) (standardized neuroanesthetic protocol with multimodal analgesia) and the control group (CG, n = 40) (intravenous anesthesia based on propofol and fentanyl). The data were collected using prospective observation of early and long-term results of lumbar fusion. After 24 months, the level of functional state and quality of life were studied. Patients in the SG did not have statistically significant changes in intraoperative hemodynamics; the best indicators of cognitive functions were noted. The effectiveness of the SG compared with the CG was confirmed by a statistically significantly lower amount of perioperative opioid drugs required (p = 0.01) and a minimal level of incisional pain (p < 0.05). An intergroup comparison of the adverse effects of anesthesia revealed a significantly lower number in the SG (n = 4) compared to the CG (n = 16) (p = 0.004). The number of postoperative surgical complications was comparable (p = 0.72). Intergroup comparison showed improved ODI, SF-36, and the Macnab scale at 24 months after surgery in the SG compared to the CG (p < 0.05). Long-term clinical results correlated with the level of incisional pain in the first three postoperative days. Our standardized neuroanesthetic protocol ensured effective treatment of postoperative incisional pain, significantly decreased the perioperative use of opioids, reduced adverse anesthesia events, and improved long-term clinical results in patients with high risk factors for anesthetic complications who undergoing open lumbar spine surgery.

Opioid Consumption Patterns and Prolonged Opioid Use Among Opioid-Naïve Ankle Fracture Patients

INTRODUCTION

Previous literature has demonstrated an association between acute opioid exposure and the risk of long-term opioid use. Here, the investigators assess immediate postoperative opioid consumption patterns as well as the incidence of prolonged opioid use among opioid-naïve patients following ankle fracture surgery.

METHODS

Included patients underwent outpatient open reduction and internal fixation of an ankle or tibial plafond fracture over a 1-year period. At patients' first postoperative visit, opioid pills were counted and standardized to the equivalent number of 5-mg oxycodone pills. Prolonged use was defined as filling a prescription for a controlled substance more than 90 days after the index procedure, tracked by the New Jersey Prescription Drug Monitoring Program up to 1 year postoperatively.

RESULTS

At the first postoperative visit, 173 patients consumed a median of 24 out of 40 pills prescribed. The initial utilization rate was 60%, and 2736 pills were left unused. In all, 32 (18.7%) patients required a narcotic prescription 90 days after the index procedure. Patients with a self-reported history of depression (P = .11) or diabetes (P = .07) demonstrated marginal correlation with prolonged narcotic use.

CONCLUSION

Our study demonstrated that, on average, patients utilize significantly fewer opioid pills than prescribed and that many patient demographics are not significant predictors of continued long-term use following outpatient ankle fracture surgery. Large variations in consumption rates make it difficult for physicians to accurately prescribe and predict prolonged narcotic use.

Acute postoperative pain management protocols in podiatric surgery within Australia: a Delphi study

Background

There is limited evidence in the literature to describe an analgesic protocol that takes into consideration the extent of foot and ankle surgery. The aim of this study was to develop a guide for acute postoperative pain management for podiatric surgery in Australia, and to identify opportunities to improve the current list of scheduled medicines available to podiatric surgeons.

Methods

A Delphi method involving 3 survey rounds was employed for this study. Twelve expert panellists in the field of podiatric surgery and anaesthesiology were invited to participate, and 10 panellists remained by the end of the study. Round 1 involved 15 open-ended questions. These answers formed the basis of the 55 statements that were developed for the following 2 survey rounds, where panellists rated the appropriateness of each statement on a 9-point Likert scale. The third survey round was an opportunity for panellists to revise their answers to each statement in light of the majority response.

Results

For mild acute postoperative pain, non-opioid oral analgesics were recommended as an appropriate management option. For moderate and severe acute postoperative pain, both non-opioid and opioid products were found to be appropriate by the majority. It was agreed that oral opioids be reserved for breakthrough pain at all severity levels. All other statements in the Delphi study pertaining to drug hypersensitivities or allergies, stratification of pain management, opioid prescription concerns, and access to pain medications were accepted as appropriate by the majority of panellists.

Conclusion

The agreed approach to acute postoperative pain management for podiatric surgeons in Australia was with a stepwise approach, utilising multimodal therapy, and reserving oral opioids for breakthrough pain. Additionally, there was consensus for podiatric surgeons in Australia to have wider access to alternative analgesics and anti-emetics that have similar or improved efficacies with better safety profiles.

Prolonged Use of a Continuous Peripheral Nerve Block Catheter for Analgesia after Pediatric Foot and Ankle Surgery

Continuous peripheral nerve blocks (CPNB) have a variety of indications and have been shown to be a safe and effective means of minimizing pain postoperatively. Early studies have indicated duration of catheter use greater than 48 hours as a main contributor to infection risk in CPNBs. Recent studies, though, have suggested that the risk of infection does not increase until 4 days after insertion. In the following case report, we recount our experience in using a continuous popliteal-sciatic peripheral nerve block for postoperative pain control in a pediatric patient following calcaneal and first metatarsal osteotomy. The catheter remained in place for 65 hours postoperatively without signs of local inflammation or infection. The prolonged CPNB use resulted in a significant decrease in postoperative opioid use and pain and increase in patient satisfaction when compared to the same procedure done one year prior on the opposite foot.
