Outcome Measures

Primary Outcomes (1)

  • Area under the pain intensity-time curve

    The smaller the area under the pain intensity-time curve, the better the nerve block effect

    Up to 48 hours postoperative

Secondary Outcomes (6)

  • Percentage of subjects without remedial analgesics

    Up to 48 hours postoperative

  • The cumulative amount of remedial analgesic drugs (oxycodone) used

    Up to 48 hours postoperative

  • Number of remedial analgesia

    Up to 48 hours postoperative

  • Number of effective patient controlled analgesia (PCA) compressions

    Up to 48 hours postoperative

  • The proportion of the number of invalid presses to the total presses

    Up to 48 hours postoperative

  • +1 more secondary outcomes

Other Outcomes (6)

  • The incidence of muscle strength and sensory abnormalities in the affected limb

    Up to 48 hours postoperative

  • The incidence of adverse reactions, such as nausea, vomiting, and neurological complications

    Up to 48 hours postoperative

  • First time to get out of bed

    Up to 48 hours postoperative

  • +3 more other outcomes

Study Arms (2)

Experimental group: Ropivacaine-controlled analgesia pump

EXPERIMENTAL

A single injection of 0.375% Ropivacaine 15 milliliters was given into the common peroneal nerve, medial sural cutaneous nerve, and lateral sural cutaneous nerve. Than,a catheter was placed in the gastrocnemius plane, and a 0.125% ropivacaine-controlled analgesic pump was applied.(The formulation was 0.125% ropivacaine at 300 milliliters, with a background dose of 3 milliliters/hours, a patient-controlled analgesia(PCA) dose of 8 milliliters, and a locking time of 25 minutes.)

Drug: Continuous Gastrocnemius plane block with ropivacaine

Control group: oxycodone-controlled analgesia pump

EXPERIMENTAL

No treatment was given preoperatively, and postoperative oxycodone patient-controlled intravenous analgesia(PCIA). After awakening, intravenous oxycodone was titrated according to numerical rating scale(NRS) score, providing analgesia without background dose of oxycodone patient-controlled intravenous analgesia(PCIA) pump (single dose 1 milligram, locking time 5 minutes, 14 hours limit 12 milligrams)

Drug: oxycodone

Interventions

After extubation, the patient was routinely monitored for his vital signs.The nerve block operation was performed by the same doctor: let the patient take the lateral decubitus position, use the ultrasonic high-frequency array probe under the popliteal socket to scan the sciatic nerve, move the probe down to find the tibial nerve and the common peroneal nerve, and then a single injection of 0.375% Ropivacaine 15milliliters was given into the common peroneal nerve, medial sural cutaneous nerve, and lateral sural cutaneous nerve. Then avoid common peroneal nerve, use the indwelling needle (16GA 3.25 IN), and put the catheter after saline expansion.

Also known as: Automatic analgesic pump
Experimental group: Ropivacaine-controlled analgesia pump

The patient was revived and received intravenous oxycodone titration according to the numerical rating scale (NRS) score, and was treated with no background dose of oxycodone patient-controlled intravenous analgesia (PCIA) pump for analgesia.

Control group: oxycodone-controlled analgesia pump
