Overview

Brief Summary

Combining tegileridine PCIA with ICNB targeting peripheral nerves, may constitute an ideal analgesic model with complementary advantages. Thus potentially achieving the analgesic goal of "early pain relief, stable throughout the process, and rapid recovery," and may have a positive impact on reducing CPSP.

Detailed Description

Combining tegileridine PCIA with ICNB targeting peripheral nerves, may constitute an ideal analgesic model with complementary advantages. ICNB provides rapid and precise incision analgesia in the early postoperative period, effectively blocking the transmission of peripheral nociceptive stimuli to the central nervous system. tegileridine PCIA, on the other hand, enhances the function of the endogenous descending pain suppression system through its central G protein pathway activation, covering the pain period after the effect of ICNB wears off and components such as visceral referred pain. At the same time, it can effectively reduce side effects such as respiratory depression and nausea/vomiting, thus potentially achieving the analgesic goal of "early pain relief, stable throughout the process, and rapid recovery," and may have a positive impact on reducing CPSP.

Arms & Interventions

sufentanil group

Active Comparator

Administer 0.15 μg/kg (maximum 10 μg) of sufentanil intravenously 40 minutes before the end of surgery, followed by the connection of a sufentanil patient-controlled intravenous analgesia (PCIA). Analgesic pump formula: Sufentanil 150 μg + 0.9% normal saline, total volume 150 mL (containing sufentanil 1 μg/mL). PCIA settings: Single loading dose 1 mL (containing sufentanil 1 μg), lockout interval 10 min, background infusion 1 mL/h.

Intervention: Sufentanil (Drug)

sufentanil group

Active Comparator

Administer 0.15 μg/kg (maximum 10 μg) of sufentanil intravenously 40 minutes before the end of surgery, followed by the connection of a sufentanil patient-controlled intravenous analgesia (PCIA). Analgesic pump formula: Sufentanil 150 μg + 0.9% normal saline, total volume 150 mL (containing sufentanil 1 μg/mL). PCIA settings: Single loading dose 1 mL (containing sufentanil 1 μg), lockout interval 10 min, background infusion 1 mL/h.

Intervention: Intercostal Nerve Block (Procedure)

Tegileridine group

Experimental

Administer 0.015 mg/kg (maximum 1mg) of tegileridine intravenously 40 minutes before the end of surgery, followed by the connection of a tegileridine patient-controlled intravenous analgesia (PCIA). Analgesic pump formula: Tigrilidine 15,000 μg + 0.9% normal saline, total volume 150 mL (containing Tigrilidine 100 μg/mL). PCIA settings: Single loading dose 1 mL (containing Tigrilidine 100 μg), lockout interval 10 min, background infusion 1 mL/h.

Intervention: Intercostal Nerve Block (Procedure)

Tegileridine group

Experimental

Administer 0.015 mg/kg (maximum 1mg) of tegileridine intravenously 40 minutes before the end of surgery, followed by the connection of a tegileridine patient-controlled intravenous analgesia (PCIA). Analgesic pump formula: Tigrilidine 15,000 μg + 0.9% normal saline, total volume 150 mL (containing Tigrilidine 100 μg/mL). PCIA settings: Single loading dose 1 mL (containing Tigrilidine 100 μg), lockout interval 10 min, background infusion 1 mL/h.

Intervention: Tegileridine (Drug)

Outcomes

Primary Outcomes

VAS (Visual Analog Scale) pain score

Time Frame: 48 hours

VAS pain score 0-10, the higher scores mean a worse outcome; Analgesic effect assessed during activity in the post-anesthesia care unit (PACU) and at 1, 6, 12, 24, 36, and 48 hours post-surgery

Secondary Outcomes

  • total dosage of remedial analgesic drugs(48hours)
  • the number of rescue analgesic interventions(48 hours)
  • overall patient satisfaction(10 days)
  • doses of remedial analgesic drugs(48hours)
  • PCIA-related parameters(48 hours)
  • Incidence of opioid-related adverse events (ORAEs)(48 hours)
  • The length of postoperative hospital stay(10 days)
  • The quality of sleep(10 days)
