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.</p><p><strong>Results: </strong>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, SPID_0-48 and SPID_0-72], 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.</p><p><strong>Conclusions: </strong>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.</p><p><strong>Trial registration: </strong>The protocol was registered in  www.chictr.org.cn  under the identifier ChiCTR2300072939.</p>","PeriodicalId":19908,"journal":{"name":"Pain and Therapy","volume":" ","pages":"283-296"},"PeriodicalIF":4.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11751199/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142771001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
