Comparison of the Analgesic Duration of 0.5% Bupivacaine With 1:200,000 Epinephrine Versus 0.5% Ropivacaine Versus 1% Ropivacaine for Low-Volume Ultrasound-Guided Interscalene Brachial Plexus Block: A Randomized Controlled Trial.

BACKGROUND: Bupivacaine and ropivacaine are the preferred long-acting local anesthetics for peripheral nerve blocks as they provide prolonged analgesia in the postoperative period. No studies have directly compared the analgesic duration of these commonly used local anesthetics in the setting of low-volume ultrasound-guided interscalene block (US-ISB). This study was designed to determine which local anesthetic and concentration provides superior analgesia (duration and quality) for low-volume US-ISB. METHODS: Sixty eligible patients scheduled for arthroscopic shoulder surgery were randomized (1:1:1) to receive US-ISB (5 mL) with 0.5% bupivacaine with 1:200,000 epinephrine, 0.5% ropivacaine, or 1% ropivacaine. All individuals were blinded including study participants, anesthesiologists, surgeons, research personnel, and statistician. All participants received a standardized general anesthetic and multimodal analgesia. The primary outcome was duration of analgesia defined as the time from the end of injection to the time that the patients reported a significant increase in pain (>3 numeric rating scale [NRS]) at the surgical site. RESULTS: The mean duration of analgesia for 0.5% bupivacaine with 1:200,000 epinephrine, 0.5% ropivacaine, or 1% ropivacaine was 14.1 ± 7.4, 13.8 ± 4.5, and 15.8 ± 6.3 hours, respectively (analysis of variance [ANOVA], P = .51). There were no observed differences in analgesic duration or other secondary outcomes between the 3 groups with the exception of a difference in cumulative opioid consumption up to 20h00 on the day of surgery in favor of ropivacaine 0.5% over bupivacaine of minimal clinical significance. CONCLUSIONS: In the context of single-injection low-volume US-ISB, we have demonstrated a similar efficacy between equal concentrations of ropivacaine and bupivacaine. In addition, increasing the concentration of ropivacaine from 0.5% to 1% did not prolong the duration of US-ISB.

Case Study Application of an Ethical Decision-Making Process for a Fragility Hip Fracture Patient.

In Canada, up to 32,000 older adults experience a fragility hip fracture. In Ontario, the Ministry of Health and Long Term Care has implemented strategies to reduce surgical wait times and improve outcomes in target areas. These best practice standards advocate for immediate surgical repair, within 48 hours of admission, in order to achieve optimal recovery outcomes. The majority of patients are good candidates for surgical repair; however, for some patients, given the risks of anesthetic and trauma of the operative procedure, surgery may not be the best choice. Patients and families face a difficult and hurried decision, often with no time to voice their concerns, or with little-to-no information on which to guide their choice. Similarly, health-care providers may experience moral distress or hesitancy to articulate other options, such as palliative care. Is every fragility fracture a candidate for surgery, no matter what the outcome? When is it right to discuss other options with the patient? This article examines a case study via an application of a framework for ethical decision-making.

Pain prevalence study in a large Canadian teaching hospital.

Despite the continued evolution of pain management techniques and an increased awareness of the importance of effective pain management, pain continues to be poorly managed. Following an earlier organization-wide pain collaborative, nursing leaders representing acute and palliative pain services together conducted a pain prevalence study. The purpose of this cross-sectional study was to evaluate the prevalence of pain and the level of interference that pain has on patient activities at a large teaching hospital. Two valid pain measurement tools, the short form of the Brief Pain Inventory (SF-BPI) and the short form of the McGill Pain Questionnaire (SF-MPQ), were chosen to be self-administered. The study revealed a pain prevalence of 71% in a mix of 114 medical and surgical adult inpatients. The SF-BPI results indicated that 31.5% of patients reported pain of moderate to severe intensity and that 11.4% of patients reported pain of severe intensity. The Nursing Advisory Council has committed to supporting an annual prevalence study as part of a corporate goal to monitor pain management across the institution. Forthcoming research will focus on including cognitively impaired patients and conducting thorough chart audits of all patients enrolled in the study. This project provided an opportunity for advanced practice nurses who share a common interest in pain, to collaborate in seeking improvements in pain management for hospitalized patients.
