Summary

The purpose of this study is to find out which pain relief method works better for people having video-assisted thoracoscopic surgery. We will compare two techniques: thoracic paravertebral block (TPVB), a numbing injection near the spine, and intrathecal morphine (ITM), a small dose of morphine injected into the spinal fluid. We want to see if ITM works as well as TPVB in reducing the need for pain medicine during the first 24 hours after surgery. People in the study will get either TPVB or ITM before going to sleep for surgery, use a patient-controlled pain pump after surgery, and have their pain scores, medicine use, recovery, and possible side effects checked for up to 30 days after surgery.

Conditions

  • Postoperative Acute Pain
  • Video-Assisted Thoracoscopic Surgery
  • Intrathechal Morphine
  • Paravertebral Peripheral Nerve Block

Interventions

PROCEDURE

Thoracic paravertebral block

Ultrasound-guided single-injection thoracic paravertebral block using 0.4 mL/kg of 0.25% bupivacaine with epinephrine (1:400,000) before induction of standardized general anesthesia. Postoperative analgesia will be provided with intravenous patient-controlled analgesia morphine, along with scheduled paracetamol and NSAIDs.

DRUG

Morphine

Single intrathecal injection of morphine (5 mcg/kg diluted in 3 mL 0.9% saline) at the L3-L4 or L4-L5 interspace before induction of standardized general anesthesia. Postoperative analgesia will be provided with intravenous patient-controlled analgesia morphine, along with scheduled paracetamol and NSAIDs.
