Brief Summary

Post-thoracotomy pain syndrome (PTPS) affects respiratory function, hindering sputum clearance and ventilation, and represents a significant complication of thoracic surgery. The analgesic effect of esketamine combined with butorphanol in PTPS is still unclear, so this study focused on this aspect.

Outcome Measures

Primary Outcomes (1)

  • Incidence of chronic pain

    To assess the patient's subjective pain intensity through the Visual Analog Pain Scale at 3 months after surgery. The Visual Analog Pain Scale consists of a line usually 100 mm in length. The ends are defined as the extreme limits of the parameter to be measured (pain) orientated from the left (no pain) to the right (worst pain). The patient makes a mark reflecting his or her perception, and the distance from the left endpoint to the mark is measured, in mm.

    3 months post-surgery

Secondary Outcomes (4)

  • Acute pain after surgery

    Within 7 days after surgery

  • Postoperative recovery quality

    Preoperative and within 3 days after surgery

  • Intraoperative mean arterial pressure

    During operation

  • Heart rate

    During operation

Study Arms (2)

Group BK

EXPERIMENTAL

Group BK received esketamine infusion at a rate of 0.3 mg/kg/h during surgery. Patients were provided with patient-controlled intravenous analgesia (PCIA) containing esketamine (1.5 mg/kg), butorphanol (0.15 mg/kg), and azasetron (20 mg) in a total volume of 100 ml within 48 hours after surgery.

Drug: EsketamineDrug: Butorphanol

Group B

PLACEBO COMPARATOR

Group B received an equivalent volume of saline during surgery. Patients were provided with patient-controlled intravenous analgesia (PCIA) containing butorphanol (0.15 mg/kg), and azasetron (20 mg) in a total volume of 100 ml within 48 hours after surgery.

Drug: Butorphanol

Interventions

In the esketamine combined with butorphanol group (Group BK), patients received an intraoperative intravenous infusion of esketamine (0.3 mg/kg/h) followed by postoperative patient-controlled intravenous analgesia (PCIA) (esketamine 1.5 mg/kg + butorphanol 0.15 mg/kg + azasetron 20 mg).

Also known as: S-Ketamine, (S)-2-(o-chlorophenyl)-2-(methylamino)cyclohexanone, L-Ketamine, (-)-Ketamine
Group BK

In the butorphanol group (Group B), patients received an equivalent volume of normal saline intraoperatively and postoperatively received PCIA without esketamine.

Also known as: Butorphanol Tartrate, Moradol, Stadol, Torbugesic, Apo-Butorphanol, Dolorex
