A Analgesic Study of Adductor Canal &IPACK Block with Liposomal Bupivacaine in Knee Arthroplasty

A Analgesic Study of Adductor Canal &IPACK Block with Liposomal Bupivacaine in Knee Arthroplasty :A Randomized,Double-controlled,Parallel-controlled,Single-center Study

To study the effectiveness of ACB and iPACK block with liposomal bupivacaine for postoperative analgesia in patients undergoing knee arthroplasty

Study Overview

Detailed Description

The pain after knee arthroplasty limits the patient's activities and postoperative recovery, and currently there are mainly three analgesic methods: intravenous analgesia, epidural analgesia and nerve block analgesia. There is a lack of studies on whether liposomal bupivacaine, if used for ACB and iPACK block, can achieve benefits in knee arthroplasty pain management by prolonging sensory nerve block without affecting muscle strength, improving patient prognosis, and shortening hospitalization days.

In this study, in order to better evaluate the effect of liposomal bupivacaine for ACB and iPACK biock on the prognosis of patients undergoing knee arthroplasty, not only the NRS and AUC of patients in each group will be observed, but also the postoperative QoR-15 Quality of Recovery Rating Scale, postoperative nausea, vomiting and other complications, and the number of hospitalization days will be also included as observation indicators. The completion of this study can provide a clinical basis for the selection of analgesic regimens for knee arthroplasty, and also provide strong evidence-based medical support for the relevant medical decision making of government departments.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: RP group:Nerve block with ropivacaine and intravenous analgesia group
The ropivacaine group will use ultrasound high-frequency line array probe for ACB and convex array probe for iPACK block before induction of general anesthesia
When the MOAA/S score is 5 after the surgery,the PCIA pump equipped with sufentanil injection will be connected,if the patient's resting NRS ≥ 4 points , they should be given sufentanil 5 ug intravenously at intervals of more than 8 minutes until NRS ≤ 3.
Experimental: LP group :Nerve block with liposomal bupivacaine and intravenous analgesia group
The liposomal bupivacaine group will use ultrasound high-frequency line array probe for ACB and convex array probe for iPACK block before induction of general anesthesia
When the MOAA/S score is 5 after the surgery,the PCIA pump equipped with sufentanil injection will be connected,if the patient's resting NRS ≥ 4 points , they should be given sufentanil 5 ug intravenously at intervals of more than 8 minutes until NRS ≤ 3.
Placebo Comparator: control group:Intravenous analgesia group
General anesthesia was induced directly
When the MOAA/S score is 5 after the surgery,the PCIA pump equipped with sufentanil injection will be connected,if the patient's resting NRS ≥ 4 points , they should be given sufentanil 5 ug intravenously at intervals of more than 8 minutes until NRS ≤ 3.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The cumulative use of analgesic drugs (sufentanil,calculated in ug)up to 48 hours postoperative in each group
Time Frame: Up to 48 hours postoperative
To study the effectiveness of ACB and iPACK block with liposomal bupivacaine for postoperative analgesia in patients undergoing knee arthroplasty.A lower dose of analgesics indicates a longer duration of block.
Up to 48 hours postoperative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
NRS scores at rest and during exerciseat at 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 36 hours, 48 hours and 72 hours postoperative
Time Frame: at 2 hours, 4 hours, 8 hours, 12 hours, 24 hours, 36 hours, 48 hours and 72 hours postoperative
The NRS typically consists of a straight line with numbers ranging from 0 to 10. Each number corresponds to a level of pain intensity:0: No pain.1 to 3: Mild pain (low intensity). 4 to 6: Moderate pain (moderate intensity). 7 to 10: Severe pain (high intensity) Patients are asked to choose a number that best represents their current pain level, where 0 means no pain, and 10 indicates the worst possible pain.A lower NRS score indicates a longer duration of block.
