Meperidine (pethidine) versus morphine in acute pain management of opioid-dependent patients

Acute Pain Management in People With Opioid Use Disorder : A Systematic Review

BACKGROUND

Guidance on acute pain management among people with opioid use disorder (OUD) is limited.

PURPOSE

To synthesize evidence on the benefits and harms of acute pain interventions among people with OUD.

DATA SOURCES

APA PsycArticles, APA PsycInfo, APA PsycExtra, Allied and Complementary Medicine Database, CINAHL, Cochrane Library, Google Scholar, Ovid Embase, Ovid MEDLINE, PubMed, Scopus, and the Web of Science Core Collection through 7 July 2024.

STUDY SELECTION

Studies of any design that evaluated acute pain interventions among adults with OUD and included pain or OUD outcomes.

DATA EXTRACTION

Independent dual screening, single-investigator data extraction with verification, and dual quality and strength of evidence assessment.

DATA SYNTHESIS

Seventeen trials, 20 controlled observational studies, and 78 uncontrolled observational studies met eligibility criteria. Continuing use of buprenorphine during acute pain episodes may be associated with similar or improved pain-related outcomes versus discontinuing, based on cohort studies conducted primarily in perioperative settings. Single well-conducted randomized controlled trials in emergency department (ED) or perioperative settings in adults not prescribed medications for OUD suggest oral clonidine, intramuscular haloperidol and midazolam with intravenous (IV) morphine, and intraoperative IV lidocaine may improve pain outcomes and warrant study in diverse patient populations. Few studies evaluated methadone or the effect of interventions on OUD outcomes.

LIMITATIONS

Most evidence is observational and at risk of bias due to confounding. All studies were conducted in ED or hospital settings, most before widespread use of high-potency synthetic opioids or among non-U.S. populations using opium.

CONCLUSION

The overall evidence for pain outcomes in people with OUD is low. The effect of pain interventions on OUD outcomes is an important evidence gap.

Patient-controlled analgesia morphine for the management of acute pain in the emergency department: a systematic review and meta-analysis

BACKGROUND

The ideal pain control approach is typically viewed as titration of analgesia for pain reduction and periodic pain evaluation. However, this method takes time and is not always possible in the crowded Emergency Department. Therefore, an alternative way to improve pain care in the Emergency Department is needed to avoid this unpleasant sensation in the patients. The best solution to tackle this situation is using Patient Controlled Analgesia (PCA), in the form of a PCA pump.

STUDY OBJECTIVES

This systematic review and meta-analysis was designated to evaluate the efficacy of PCA morphine in treating acute pain at Emergency Department.

METHODS

We searched databases Cochrane Central Register of Controlled Trials (CENTRAL), Medline, and Google Scholar up to February 2022 and identified randomized controlled trials with English language only that compare PCA morphine to IV morphine in treating patients presenting with acute pain at Emergency Department.

RESULTS

Eight trials were included in our review, comprising 1490 participants. We compared PCA morphine vs. IV morphine. There were no differences in the pain score between PCA and IV morphine (standard mean difference [SMD] = -0.20, p = 0.25). Further subgroup analyses (origin of the pain, time of assessment and the durations) showed no difference except for the dosages as the PCA morphine reduced the pain compared to IV morphine in low and high dosages but only two studies were involved. However, the analysis showed PCA morphine increased patient satisfaction and reduced the number of patients who required additional analgesia compared to IV morphine (MD 0.12, P < 0.001), (MD 0.47, P < 0.001) respectively. Data obtained in this review pertaining to adverse effects such as nausea, vomiting, pruritus, and drowsiness is limited since not all the trials reported the events.

CONCLUSIONS

PCA morphine do appear to have a beneficial effect on the outcome of patient satisfaction and the number of patients who required additional analgesia. However, further studies targeting a larger sample size is required to increase the certainty of the evidence.

Synchronized extracorporeal shockwave lithotripsy may still affect the heart: a case report of perioperative ST-segment elevation myocardial infarction

Extracorporeal shockwave lithotripsy (ESWL) is widely used as a primary treatment for urolithiasis and is performed as an elective outpatient surgical procedure because of its ease of use. However, patients undergoing this treatment rarely develop cardiac complications. In this article, we present the case of a 45-year-old male patient who presented with ST-elevation myocardial infarction during ESWL. Moreover, atypical symptoms and electrocardiogram patterns were recognized by the nursing staff. Early primary evaluation and intervention resulted in favorable outcomes along with patent coronary artery flow following stent placement for stenosis, and no complications were noted.

Patient controlled analgesia for the management of acute pain in the emergency department: A systematic review

BACKGROUND

The most common presenting complaint to the emergency department (ED) is pain. Several studies have shown that a large proportion of ED patients either receive no or sub-optimal analgesia. Patient-controlled analgesia (PCA) pumps used in the post-operative setting has shown to decrease total opioid consumption and has increased patient and nurse satisfaction.

OBJECTIVE

The purpose of this systematic review was to evaluate clinical trials that have used PCAs in the ED setting, to evaluate safety and efficacy as well as patient and healthcare provider experience.

METHODS

A search of PubMed, MEDLINE, and the Cochrane Database was conducted using the MESH search terms emergency department, patient-controlled analgesia, and acute pain up to September 2021. These terms were searched in all fields of publication and were limited to the English-language articles, clinical "human" studies, and studies that included the use of patient-controlled analgesia in the setting of the emergency department.

RESULTS

The search initially identified 227 potentially relevant articles and a total of 10 studies met criteria for inclusion. ED use of PCA therapy was associated with increased patient satisfaction, decreased pain scores, and an overall increase in opioid consumption.

CONCLUSION

The quality, the differences in study methods and outcome measures used, and heterogeneity of the studies performed to date do not provide adequate evidence to support its widespread use in the ED. Well-designed studies conducted in the ED are still needed to evaluate the ideal patient population to whom these PCAs may provide the most benefit as well as a robust cost-analysis to ensure feasibility of use in the future.
