Abstract
Introduction: Single-injection pericapsular nerve group (PENG) block with ropivacaine provides clear analgesic effects in preoperative pain management for hip fractures. However, it suffers from insufficient duration, failing to meet the needs of most patients. This single-center, randomized controlled, observer-blinded trial utilizes a novel combination of liposomal bupivacaine (LB) single-injection PENG block to examine its efficacy, duration, and safety in preoperative analgesia for hip fractures, aiming to develop a new preoperative analgesic protocol.
Methods: Sixty-six patients with hip fractures received ultrasound-guided single-injection PENG block with LB or ropivacaine after admission. The primary outcome was the static and dynamic pain scores measured at 48 h post-block. Pain scores at 12, 24, 36, 60, and 72 h post-block, rescue analgesia rate, time to first opioid, additional morphine consumption, and adverse events were assessed as the secondary outcomes.
Results: LB versus ropivacaine group at 48 h post-block, with a median interquartile range (IQR) of 2 (1.0-2.0) versus 3 (2.0-3.0) at static pain score and 2 (1.75-3.0) versus 4 (4.0-5.0) at dynamic pain score. LB group had lower dynamic and static pain scores at other observation points except for the static pain score at 72 h, lower pain intensity [sum of pain intensity difference (SPID)0-24, SPID0-48 and SPID0-72], longer time to first opioid, lower additional morphine consumption, and lower incidence of nausea and vomiting. No significant inter-group differences were detected in other secondary outcomes.
Conclusions: For preoperative analgesia of hip fractures, LB single-injection PENG block had a similar analgesic intensity and safety as ropivacaine but provided a longer duration of analgesia, reaching 48 h and even extending beyond 60 h, which reduced opioid consumption and extended time to the first opioid.
Trial registration: The protocol was registered in www.chictr.org.cn under the identifier ChiCTR2300072939.
期刊介绍:
Pain and Therapy is an international, open access, peer-reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of pain therapies and pain-related devices. Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to, acute pain, cancer pain, chronic pain, headache and migraine, neuropathic pain, opioids, palliative care and pain ethics, peri- and post-operative pain as well as rheumatic pain and fibromyalgia.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports, trial protocols, short communications such as commentaries and editorials, and letters. The journal is read by a global audience and receives submissions from around the world. Pain and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
