Enhanced Recovery After Surgery-Based Multimodal Preemptive Analgesia for Perioperative Management in Transarterial Chemoembolization of Intermediate-to-Advanced Hepatocellular Carcinoma

Enhanced Recovery After Surgery-Based Multimodal Preemptive Analgesia for Perioperative Management in Transarterial Chemoembolization of Intermediate-to-Advanced Hepatocellular Carcinoma: a Multicenter Retrospective Cohort Study

To evaluate the effectiveness of the combination of hydrochloride hydromorphone and flurbiprofen ester for post-TACE intravenous patient-controlled intravenous analgesia (PCIA).

This multicenter retrospective study analyzed clinical data from 129 patients with intermediate or advanced HCC who underwent TACE at three centers. Patients were divided into perioperative analgesia protocol groups: Group A (n=85) received patient-controlled intravenous analgesia-based multimodal preemptive analgesia (hydromorphone hydrochloride 6 mg, flurbiprofen axetil 50 mg) with background infusion. Group B (n=44) received conventional on-demand analgesia (intraoperative intravenous flurbiprofen axetil 50 mg, intramuscular tramadol 100 mg as needed for pain). Outcome measures included numerical rating pain scale scores, perioperative adverse events, inflammatory markers, hepatic function indicators, analgesia satisfaction, and cost-effectiveness.
