Objectives: The pericapsular nerve group (PENG) block was first described for analgesia of hip fracture in 2018. We hypothesised that the PENG block is safe and effective for patients with hip fracture when provided by emergency physicians and trainees in the ED. Methods: This was an observational study of routine care. Consecutive patients receiving regional anaesthesia for hip fracture at a single ED were prospectively enrolled. Pain scores were assessed prior to regional anaesthesia then at 15, 30 and 60 min after administration. Maximal reduction in pain scores within 60 min were assessed using the Visual Analogue Scale (at rest and on movement) or the Pain Assessment IN Advanced Dementia tool (at rest). Patients were followed for opioid use for 12 h after regional anaesthesia and adverse events over the duration of admission. Results: There were 67 eligible patients during the enrolment period, with 52 (78%) prospectively enrolled. Thirty-three received femoral blocks (19 fascia iliaca compartment blocks, 14 femoral nerve blocks) and 19 received a PENG block. Inexperienced providers were able to successfully perform the PENG block. There was no difference in maximum pain score reduction between the groups. There was no difference in adverse effects between groups. Opioid use was similar between the groups. More patients were opioid-free after a PENG block. Conclusions: The present study demonstrated that the PENG block can be provided safely and effectively to patients with hip fracture in the ED. On the basis of this pilot study, a larger randomised controlled study should now be designed.

Pelvic fragility fractures, such as pubic ramus fractures, are a common and painful condition in the elderly population. Despite this, there are few regional anaesthesia options available to effectively relieve pain in these fracture types and avoid potential side effects from opioid administration. This case report describes an elderly patient with a superior ramus fracture, who received effective pain relief with motor sparing, using a standard‐volume point‐of‐care ultrasound‐guided pericapsular nerve group (PENG) block performed in the emergency department. The standard‐volume PENG block performed by an emergency clinician appears to be a safe, effective and feasible regional anaesthesia technique for superior pubic ramus fracture, with the additional benefit of motor sparing that may potentially facilitate earlier mobilisation and discharge.

Background The pericapsular nerve group (PENG) block was first described for the treatment of hip fracture, including neck of femur, in 2018. We hypothesise that the PENG block is safe and effective for patients with hip fracture when provided by emergency physicians and trainees in the emergency department (ED), for which it may be superior to fascia iliaca compartment block (FICB) and femoral nerve block (FNB). Methods From October 2019 to July 2020, consecutive patients receiving regional anaesthesia for hip fracture in the ED of a single large regional hospital were prospectively enrolled. Pain scores were assessed prior to regional anaesthesia then at 15, 30 and 60 minutes after regional anaesthesia. Maximal reduction in pain scores within 60 minutes were assessed using the Visual Analogue Scale (at rest and on movement) or the Pain Assessment IN Advanced Dementia tool (at rest). Patients were followed for opioid use for 12 hours after regional anaesthesia and adverse events over the duration of their admission. Results There were 67 eligible patients during the enrolment period, with 52 (78%) prospectively enrolled. Thirty-three received femoral blocks (19 FICB, 14 FNB) and 19 received a PENG block. There was no difference in maximum pain score reduction between the groups whether measured at rest or on movement. Clinicians providing the PENG block were less experienced in the technique than those providing FICB or FNB. There was no difference in adverse effects between groups. Although opioid use was similar between the groups, more patients were opioid free after a PENG block. Conclusions Although there was no difference in maximal pain score reduction, this study demonstrated that the PENG block was feasible and could be provided safely and effectively to patients with hip fracture in the ED. On this basis, a larger randomised controlled study should now be designed.
