Arthroscopic bankart surgery: Does gabapentin reduce postoperative pain and opioid consumption? A triple-blinded randomized clinical trial

Opioid-Sparing Anesthesia: Gabapentin and Postoperative Pain

PURPOSE

Nonopioid analgesics are commonly used to augment or replace opioids in the perioperative setting. Perianesthesia nurses must consider timing and appropriateness when administering these medications to patients in the preoperative area or the postanesthesia care unit, particularly when other medications with sedative effects are being given. Gabapentin, originally proposed as an anticonvulsant medication, promotes analgesia and reduces risk for postoperative nausea and vomiting. This review examines the effect of gabapentin on postoperative pain.

DESIGN

A systematic review.

METHODS

CINAHL, PubMed, and Cochrane Review databases were searched to find a total of 93 sources that examined gabapentin and postoperative pain. After applying inclusion and exclusion criteria, four randomized controlled trials (RCT) were reviewed. Postoperative pain within the 24 hours of surgery was measured as the primary outcome using the visual analog scale in all sources FINDINGS: Three of the four reviewed RCTs determined gabapentin was both statistically and clinically significant in reducing postoperative pain, and all four sources showed a reduction in opioid consumption during the immediate postoperative period, which promoted patient satisfaction.

CONCLUSIONS

Further study of gabapentin and postoperative pain is needed employing rigorous and robust methodology and diversity of the sample selections.

Pain Control After Shoulder Arthroscopy: A Systematic Review of Randomized Controlled Trials With a Network Meta-analysis

BACKGROUND

Shoulder arthroscopy is one of the most commonly performed orthopaedic procedures used to treat a variety of conditions, with >500,000 procedures performed each year.

PURPOSE

To systematically review the randomized controlled trials (RCTs) on pain control after shoulder arthroscopy in the acute postoperative setting and to ascertain the best available evidence in managing pain after shoulder arthroscopy to optimize patient outcomes.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A systematic review of the literature was performed based on the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines. Studies were included if they were RCTs evaluating interventions to reduce postoperative pain after shoulder arthroscopy: nerve blocks, nerve block adjuncts, subacromial injections, patient-controlled analgesia, oral medications, or other modalities. Meta-analyses and network meta-analyses were performed where appropriate.

RESULTS

Our study included 83 RCTs. Across 40 studies, peripheral nerve blocks were found to significantly reduce postoperative pain and opioid use, but there was no significant difference among the variable nerve blocks in the network meta-analysis. However, continuous interscalene block did have the highest P-score at most time points. Nerve block adjuncts were consistently shown across 18 studies to prolong the nerve block time and reduce pain. Preoperative administration was shown to significantly reduce postoperative pain scores (P < .05). No benefit was found in any of the studies evaluating subacromial infusions.

CONCLUSION

Continuous interscalene block resulted in the lowest pain levels at most time points, although this was not significantly different when compared with the other nerve blocks. Additionally, nerve block adjuncts may prolong the postoperative block time and improve pain control. There is promising evidence for some oral medications and newer modalities to control pain and reduce opioid use. However, we found no evidence to support the use of subacromial infusions or patient-controlled analgesia.

Opioid requirement after rotator cuff repair is low with a multimodal approach to pain

BACKGROUND

Current practices may aim to blunt rather than understand postoperative pain. Perhaps the most common serious complication of arthroscopic rotator cuff repair (ARCR) is persistence of opiate medication intake. Patients still receive upwards of 80 oxycodone 5 mg pills, or 600 morphine milligram equivalents (MMEs), leading more than 20% of opioid-naïve subjects to continue to fill opioid prescriptions beyond 180 days after surgery. Developing evidence-based guidelines for narcotic prescription after ARCR presents an opportunity for orthopedic surgeons to address the opioid epidemic.

PURPOSE

The purpose of this study was (1) to prospectively determine the requirements for opiate medications after ARCR, and (2) to create an evidence-based guideline for postoperative prescription, in contrast to the anecdotal or expert panel recommendations that currently exist. We further investigated whether a liposomal bupivacaine (LB) interscalene never block (ISNB) would reduce pain and opiate consumption compared with standard bupivacaine ISNB (control) for ARCR.

METHODS

The study enrolled 100 patients who underwent primary ARCR surgery. Patients were provided with postoperative "pain journals" to document their daily pain on a numerical rating scale, satisfaction with pain management using the Likert scale, and track their daily oxycodone 5 mg pill consumption during the 14-day postoperative period. Enrolled patients were further randomized to receiving an LB (experimental) or standard bupivacaine (control) ISNB.

RESULTS

A total of 77% of all patients required fewer than 15 pills postoperatively. The LB group consumed an average of 1.7 fewer pills (13.0 MMEs) on postoperative day (POD) 1 (P = .02) and reported statistically lower pain during PODs 1 and 2 (P = .01 and P = .006), as well as cumulatively throughout the study period (P = .03). In addition, LB patients remained opioid-free at a higher rate (44% vs. 15% in controls, P = .03).

CONCLUSION

With a multimodal approach, the majority of patients undergoing ARCR can manage postoperative pain with 15 or fewer oxycodone 5 mg tablets (112.5 MMEs) and maintain a high degree of satisfaction. The addition of an LB ISNB may further reduce the consumption of postoperative narcotics compared with a standard ISNB. This study provides evidence that may be used for surgeon guidelines in the effort to reduce opioid prescriptions after ARCR.

Opioid Use Is Reduced in Patients Treated with NSAIDs After Arthroscopic Bankart Repair: A Randomized Controlled Study

Purpose

To evaluate the efficacy of oral nonsteroidal anti-inflammatory drugs (NSAIDs) as the primary postoperative pain medication compared with standard oral opioids after arthroscopic shoulder capsulolabral (Bankart) repair for recurrent anterior shoulder instability.

Methods

This was a single-center, prospective, randomized controlled study. Patients aged 18 to 65 years indicated for arthroscopic shoulder capsulolabral repair for recurrent anterior shoulder instability were included. Postoperatively, patients were prescribed 1 of 2 analgesic regimens: (1) 30 ibuprofen (600 mg every 6 to 8 hours as needed) and 10 tablets of oxycodone/acetaminophen (5/325 mg every 6 hours as needed for breakthrough pain) or (2) 30 tablets oxycodone/acetaminophen (5/325 mg every 6 hours as needed). Subjects completed questionnaires at 24, 48, and 96 hours and 1 week after surgery, which included questions about analgesic medication usage, visual analog scale (VAS) pain score, incidence of adverse events, and patient satisfaction.

Results

Between December 2017 and May 2019, 80 patients (mean age 31.3 ± 10.4 years) were enrolled. Overall there were no significant differences in VAS pain score or patient satisfaction between the 2 groups. Patients in the opioid-only group had a significantly higher mean opioid consumption on postoperative days (PODs) 2 to 4 (5.5 versus 2.9, P = .05) and after 1 week (11.7 versus 7.9 tablets, P = .05) compared with patients in the NSAID group. Of patients in the NSAID group, 17.5% experienced adverse effects, compared with 35% in the opioid-only group.

Conclusions

Use of oral NSAIDs with limited breakthrough opioids results in significantly less opioid use after arthroscopic Bankart repair in the first postoperative week compared with opioids only. Both groups used limited amounts of opioids to control postoperative pain. There were no differences in pain levels at any time point postoperatively or satisfaction between patient groups.

Perioperative pain management for shoulder surgery: evolving techniques

Improving management of postoperative pain following shoulder surgery is vital for optimizing patient outcomes, length of stay, and decreasing addiction to narcotic medications. Multimodal analgesia (ie, controlling pain via multiple different analgesic methods with differing mechanisms) is an ever-evolving approach to enhancing pain control perioperatively after shoulder surgery. With a variety of options for the shoulder surgeon to turn to, this article succinctly reviews the pros and cons of each approach and proposes a potential pain management algorithm.

Review: Does Gabapentin Relieve Opioids, Cannabis and Methamphetamines Addictions?

The study reviews the suitability of using Gabapentin for treating opioid, cannabis and methamphetamine use disorders. This revision consists of 61 biographical references based on a PubMed database search (January of 1983-May of 2018). Gabapentin displayed respectively 50% and 66.7% of success for treating methamphetamine dependence and opioid withdrawal symptoms. Furthermore, a few research studies have reported Gabapentin´s efficacy for alleviating cannabis dependence (two studies), and cannabis withdrawal symptoms (one study). Similarly, a single study reported Gabapentin reduction of opioid consumption during the detoxification process. Based on the revision, we can conclude that: (a) Gabapentin is useful for treating opioid withdrawal symptoms, (b) additional studies are necessary for elucidating the effectiveness of Gabapentin for treating methamphetamine dependence, cannabis dependence and its withdrawal symptoms, and (c) more studies are necessary to confirm the efficacy of Gabapentin in reducing opioid consumption during detoxification.

The Effect of Pre-emptive Dexketoprofen Administration on Postoperative Pain Management in Patients with Ultrasound Guided Interscalene Block in Arthroscopic Shoulder Surgery

Background: Postoperative pain is an important problem for patients undergoing shoulder surgery. Our study investigated analgesic efficacy, duration of analgesia, postoperative analgesic use and patient satisfaction with the use of preemptive intravenous dexketoprofen for interscalene block in addition to general anesthesia in arthroscopic shoulder surgery. Methods: 60 patients, scheduled for arthroscopic shoulder surgery were randomized (30 patients each) into either: - control group (Group1) or dexketoprofen group (Group 2). Patients were followed for 48 hours to compare both groups for; post-operative pain scores, effectiveness of postoperative analgesia, duration of analgesia, and analgesia consumption. Duration of postoperative sensory block of the shoulder joint was defined as time to onset of pain at the incision site. Duration of postoperative motor block of the shoulder joint was defined as time to onset of first shoulder movement. Results: While no significant difference was determined for motor block time, sensory block time was significantly longer in the dexketoprofen group (p < 0.05).VAS scores were significantly lower at all times in the dexketoprofen group (p < 0.05).Total PCA fentanyl consumption was 274.16 ± 314.89 (μg) in the dexketoprofen group, and 490.00 ± 408.98 (μg) in the control group, the difference was statistically significant (p < 0.05). No significant difference was observed between the groups' demographic and hemodynamic data. Conclusion: Pre-emptive IV dexketoprofen may be a good option for arthroscopic shoulder surgery and provides effective analgesia.

Effects of a single dose of preoperative pregabalin and gabapentin for acute postoperative pain: a network meta-analysis of randomized controlled trials

Background

Pregabalin (PGB) and gabapentin (GBP) are current and emerging drugs in the field of pre-emptive preoperative analgesia. However, the role of PGB or GBP in acute postoperative pain management still remains elusive.

Materials and methods

We conducted a comprehensive literature search of articles published by December 3, 2017. A total of 79 randomized controlled trials with 6,201 patients receiving single-dose premedication were included. Through a network meta-analysis (NMA), we validated the analgesic effect and incidence of adverse events by using various doses of PGB or GBP administration.

Results

NMA results suggested that the analgesic effect may be dose related. For 24-hour opioid consumption, a consistent decrease was found with the increase in the dose of PGB or GBP. For 24-hour pain score at rest, a high dose (≥150 mg) of PGB was more effective in decreasing pain score than a dose of 75 mg, and a high dose (≥900 mg) of GBP reduced pain intensity than doses of 300 or 600 mg. Moreover, the incidence of adverse reactions varied with varying doses of PGB or GBP.

Conclusion

A dose-response relationship was detected in opioid consumption and postoperative pain for a single-dose preoperative administration of PGB and GBP. Making reasonable choice of drugs and dosage may prevent the occurrence of adverse reactions.

Updates on Multimodal Analgesia for Orthopedic Surgery

Pain control after orthopedic surgery is challenging. A multimodal approach provides superior analgesia with fewer side effects compared with opioids alone. This approach is particularly useful in light of the current opioid epidemic in the United States. Several new nonopioid agents have emerged into the market in recent years. New agents included in this review are intravenous acetaminophen, intranasal ketorolac, and newer nonsteroidal anti-inflammatory drugs, and the established medications ketamine and gabapentinoids. This article evaluates the evidence supporting these drugs in a multimodal context, including a brief discussion of cost.

The Importance of Optimizing Acute Pain in the Orthopedic Trauma Patient

Postoperative pain control is a highly studied topic because of its significant effect on costs, hospital course, and, most importantly, patient satisfaction. Opioid use has been the "status quo" of postoperative pain management but prolongs hospital stays and increases complications. Optimizing acute pain management in patients with orthopedic trauma is important and can translate into significant positive physiologic and financial outcomes. Although multiple viable examples of optimizing acute pain management in the literature demonstrate outcome improvements, implementation has not been widespread. Significant outcome success will depend more on systemwide implementation than a specific regimen for postoperative pain control.
