Brief Summary

The purpose of this study was to investigate the effect of bupivacaine liposomes on postoperative pain in TKA ( total knee replacement ) patients.The main questions answered are:

  1. 1.Is bupivacaine liposomes superior to bupivacaine in femoral triangle block or adductor block in terms of 72 hours opioid consumption after knee replacement
  2. 2.Which block method(Femoral triangle block or adductor block) combined with bupivacaine liposome was more effective in alleviating pain score and 72 hours opioid consumption after total knee surgery.
  3. 3.Receive liposomal bupivacaine or bupivacaine as a regional anesthetic for femoral triangle block or adductor block under ultrasound guidance.
  4. 4.Undergo total knee replacement surgery under spinal anesthesia.
  5. 5.Follow-up within 72 hours after surgery , opioid consumption, NRS score, PCA(Patient controlled analgesia,PCA) data, first postoperative remedial analgesia time, quadriceps muscle strength and complications were recorded

Outcome Measures

Primary Outcomes (1)

  • Opioid consumption 72 hours after surgery

    This primary outcome entails tracking and assessing the total opioid consumption by participants following total knee replacement surgery. The evaluation includes quantifying the amount of opioids prescribed and consumed by participants for pain management post-surgery. Opioid medications administered will be converted to morphine equivalents based on established conversion ratios. By analyzing overall opioid consumption, the study aims to evaluate the efficacy of the interventions in managing postoperative pain.

    this outcome will be monitored and recorded within 72 hours postoperatively

Secondary Outcomes (4)

  • Pain intensity

    Pain intensity will be measured at 8 time points: 6 hours, 12 hours, 18 hours and 24 hours 36 hours, 48 hours, 60 hours, 72 hours post-surgery

  • Time to First Rescue Analgesic

    72 hours after surgery

  • Total opioid dosage and PCA times

    Total opioid dosage and PCA times were recorded at 8 time points: 6 hours, 12 hours, 18 hours and 24 hours 36 hours, 48 hours, 60 hours, 72 hours post-surgery

  • Quadriceps muscle strength

    24.48,72 hours after surgery

OUTCOMES ASSESSOR
Masking Details
Double (Participant, Outcomes Assessor) . Given the distinct visual appearance of the liposomal bupivacaine (milky white) and bupivacaine (transparent), a double-blind study design is not feasible. Consequently, this study employs a single-blind approach where neither participants nor outcome assessors will be aware of treatment allocation. Healthcare providers administering the study drug will be aware of the treatment group assignment. Rigorous procedures will be implemented to minimize potential bias, including standardized outcome assessment tools, blinded data entry, and independent data analysis.
Purpose
TREATMENT
Intervention Model
FACTORIAL
Model Details: This study utilizes a factorial interventional design, where participants undergoing total knee arthroplasty surgery will be allocated into four separate groups. Group one will receive liposomal bupivacaine plus bupivacaine as a regional anesthetic for adductor block, the group two will receive bupivacaine for adductor block; the group three will receive liposomal bupivacaine plus bupivacaine as a regional anesthetic for femoral nerve block ; Group four will receive bupivacaine as a regional anesthetic for femoral nerve block .Two types of interventions are involved, namely, choice of anesthesia mode (2 levels: adductor block, femoral triangle block) and anesthetic administration (2 levels: bupivacaine liposomes and bupivacaine mixture, bupivacaine).The study aims to compare the analgesic efficacy, duration of pain relief, opioid consumption, between the four groups .
