Use of indomethacin for pain relief following scleral buckling surgery

Efficacy of peribulbar bupivacaine at the end of surgery in the management of postoperative pain after scleral buckling

PURPOSE

To compare the efficacy of peribulbar bupivacaine with routine analgesics for pain management in patients undergoing scleral buckling.

METHODS

In total, 72 patients undergoing scleral buckling or combined with vitrectomy were enrolled in this study. Patients were randomized into two groups, each containing 36 patients. Patients of group A received 5 mL of bupivacaine (0.5%) injection at the end of surgery, whereas group B patients received routine analgesics. The postoperative pain score was assessed in the first 24 hours of the postoperative period with the visual pain analog score.

RESULTS

Maximum postoperative pain scores were lower in patients receiving bupivacaine block (median: 3; range: 3-7) than in the control group (median: 5; range: 3-9). Pain scores in group A were lower than in the control group both at 3 and 6 hours after surgery, which was statistically significant ( P < 0.001). Four patients in group A and 17 patients in group B needed additional analgesia in the first 24 hours of the postoperative period. In addition, two patients in group A and seven patients in group B experienced episodes of nausea and vomiting in the first 24 hours of surgery.

CONCLUSION

The results of this study suggest that the postoperative experience of patients undergoing scleral buckling surgery can be made more comfortable with the use of bupivacaine block at the end of surgery.

Analysis of ophthalmology subspecialty opioid prescribing patterns during the opioid public health crisis

OBJECTIVE

To describe opioid prescribing practices of ophthalmology subspecialties and determine whether opioid prescribing has decreased during the public health crisis.

DESIGN

Retrospective cohort study.

PARTICIPANTS

Ophthalmologists prescribing at least 11 medications billed to the Medicare Part D prescription drug plan.

METHODS

Publicly available Medicare data sets based on claims from the years 2016, 2017, and 2018 were used. Fellowship status was assumed based on subspecialty society membership or use of specified Current Procedural Terminology codes. The main outcome was the percentage of physicians in each subspecialty prescribing opioids.

RESULTS

The database included 19,762, 19,790, and 19,840 ophthalmologists in the years 2016, 2017, and 2018, respectively. Only the subspecialties of comprehensive ophthalmology (43.5% vs 39.6% vs 35.7%; p < 0.001; φc = 0.066), retina (66.5% vs 60.7% vs 54.5%; p < 0.001; φc = 0.101), cornea (82.8% vs 83.9% vs 77.2%; p = 0.03; φc = 0.076), and glaucoma (53.4% vs 46.4% vs 42.0%; p < 0.001; φc = 0.094) underwent a small but significant reduction in the proportion of physicians prescribing opioids. The subspecialties of oculoplastics (86%-88.8%), cornea (77.2%-82.8%), retina (54.5%-66.5%), and pediatrics (51.5%-57.9%) had the highest percentage of physicians prescribing opioids. The subspecialties of glaucoma, uveitis, and comprehensive ophthalmology had the lowest percentage of opioid prescribers. Among physicians with more than 10 opioid claims, median opioid claims did not change drastically. Opioids contributed only a small proportion of medication claims for all subspecialties.

CONCLUSION

All subspecialties experienced either a small reduction or no significant change in the percentage of opioid prescribers during the period analyzed. We hope to encourage collaboration between ophthalmology subspecialties in striving to reduce opioid prescribing. Further studies are needed to better fine-tune opioid prescribing practices.

Association Between Opioid Prescribing Patterns and Abuse in Ophthalmology

Importance

Drug overdoses have become the number 1 cause of mortality in American adults 50 years and younger. Prescription opioid abuse is a growing concern that has garnered widespread attention among policymakers and the general public.

Objective

To determine the opioid prescribing patterns among ophthalmologists and elucidate their role in the prescription opioid abuse epidemic.

Design, Setting, and Participants

In this observational cohort study, beneficiaries and their physicians were analyzed using 2013 to 2015 Medicare Part D Prescriber Data. The Centers for Medicare and Medicaid Services Medicare Part D Prescriber Public Use Files for 2013, 2014, and 2015 were accessed. Analysis began in June 2017. Data were collected and analyzed regarding the prescribing patterns for opioid drugs (eg, number of prescriptions written including refills, number of days' supply, and prescriber rates) for all participating ophthalmologists.

Main Outcomes and Measures

The mean number of opioid prescriptions written annually by ophthalmologists; prescriber rates compared with all prescriptions written; and geographic distribution of opioid prescriptions written per ophthalmologist.

Results

In 2013, 4167 of 19 615 ophthalmologists were women (21.2%). Consistently, most ophthalmologists (88%-89%) wrote 10 opioid prescriptions or fewer annually. Approximately 1% (0.94%-1.03%) of ophthalmologists wrote more than 100 prescriptions per year. On average, ophthalmologists wrote 7 opioid prescriptions per year (134 290 written annually by 19 638 physicians, on average) with a mean supply of 5 days. The 6 states with the highest volume of opioid prescriptions written annually per ophthalmologist were located in the southern United States.

Conclusions and Relevance

In general, ophthalmologists show discretion in their opioid prescribing patterns. The present opioid abuse epidemic should prompt physicians to consider revisiting their prescribing protocols given the high risk for dependency.

The Combination of Ketorolac with Local Anesthesia for Pain Control in Day Care Retinal Detachment Surgery: A Randomized Controlled Trial

This study aims to evaluate the efficacy of ketorolac with local anesthesia compared to local anesthesia alone for perioperative pain control in day care retinal detachment surgery. The randomized controlled trial included 59 eyes of 59 participants for retinal detachment surgery who were randomly assigned (1 : 1) into the ketorolac (K) group and control (C) group. All participants underwent conventional local anesthesia while patients in the K group received an extra administration of preoperative ketorolac. Participants in the K group had a statistically significantly lower intraoperative NRS score (median 1.0 versus 3.0, P = 0.003), lower postoperative NRS score (median 0 versus 1.0, P = 0.035), fewer proportion of rescue analgesic requirement (10% versus 34.5%, P = 0.023), and lower incidence of postoperative nausea and vomiting (13.3% versus 41.4%, P = 0.015) compared to the C group. Intraocular pressure (IOP) changes (△IOP) were significantly reduced in the K group (median 1.9 versus 3.0, P = 0.038) compared to the C group 24 hours postoperatively. In conclusion, the combination of local anesthesia with ketorolac provides better pain control in retinal detachment surgery compared to local anesthesia alone. The beneficial effect of ketorolac with local anesthesia may contribute to a wider-spread adoption of day care retinal detachment surgery. This trial is registered with ClinicalTrials.gov NCT02729285.

Single dose oral indometacin for the treatment of acute postoperative pain

BACKGROUND

Indometacin is a non-steroidal anti-inflammatory drug (NSAID) used most commonly for the treatment of inflammation and pain resulting from rheumatic disease (arthritis), and less commonly in postoperative pain management. When taken for chronic pain conditions, indometacin has been associated with a high incidence of adverse events. The benefits and harms of orally-administered indometacin for postoperative pain are not clear.

OBJECTIVES

To determine the efficacy of a single dose of oral indometacin compared with placebo in treating acute postoperative pain in adults, and to analyse information relating to adverse events.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials in The Cochrane Library (Issue 3, 2004), MEDLINE, EMBASE and the Oxford Pain Relief Database for relevant studies. Additional studies were sought from the reference lists of retrieved reports.

SELECTION CRITERIA

Studies were included in the review if they were randomised, double blind, placebo-controlled clinical trials using a single oral dose of indometacin in adults with acute postoperative pain.

DATA COLLECTION AND ANALYSIS

Trials were assessed independently by two authors. Pain relief or pain intensity data were extracted and converted into dichotomous information to give the number of patients with at least 50% pain relief over four to six hours. The relative benefit for at least 50% pain relief was calculated.

MAIN RESULTS

One trial of 59 women with post-episiotomy pain met the inclusion criteria. The dose of indometacin assessed against placebo was 50 mg, and the results concluded that indometacin was not significantly better than placebo for relieving postoperative pain at four to six hours. There was insufficient information to conduct further efficacy analyses or assess adverse events.

REVIEWERS' CONCLUSIONS

Conclusions about the clinical efficacy of indometacin for postoperative cannot be made until more trials are conducted for a variety of surgical procedures, and different doses of indometacin are assessed.

Effective analgesic modalities for ambulatory patients

The introduction of government-mandated standards for pain management has focused our attention on postoperative pain. With the recent JACHO standards' for ambulatory surgery, it is imperative that all health care workers who care for these patients are familiar with appropriate pain management. Developments in our understanding of the pathophysiology of acute pain have further enhanced our ability to improve pain management for postoperative ambulatory patients. This has led to the concept of preventive analgesia (inhibition of physiological and pathological secondary inflammatory pain). Extensive work has shown that this is best achieved using a multimodel approach usually consisting of an NSAID, opioid, and local anesthetic. NMDA antagonists (ketamine, dextromethorphan) and alpha-2 agnoists (clonodine) show potential supplements to further enhance pain management, especially if given preemptively. Nonpharmacological intervention such as cold therapy or acupuncture may also be considered. The armanentarium for effective pain management has improved substantially over the past few years. The challenge is for health care workers to implement these therapies to obtain optimum pain management in ambulatory surgical patients.
