Thoracic paravertebral block for breast cancer surgery: a randomized double-blind study

Area of Science:

• Anesthesiology
• Surgical Oncology
• Pain Management

Background:

• Postoperative pain management is crucial after breast cancer surgery.
• Multilevel paravertebral block is a regional anesthesia technique.
• Evaluating its efficacy with propofol general anesthesia and laryngeal mask is important.

Purpose of the Study:

• To determine if multilevel paravertebral block enhances postoperative analgesia after breast cancer surgery.
• To compare the efficacy of ropivacaine paravertebral block versus placebo.

Main Methods:

• A randomized, double-blind study involving 79 patients undergoing breast cancer surgery.
• Patients received either ropivacaine 0.5% or isotonic saline paravertebral injection before general anesthesia.
• Postoperative fentanyl consumption and pain scores were assessed.

Main Results:

• The ropivacaine group showed significantly less fentanyl consumption in the postanesthesia care unit (PACU).
• Fewer patients in the ropivacaine group reported severe pain (numeric rating scale ≥3) in the PACU.
• No significant differences in pain or analgesic consumption were observed after PACU discharge.

Conclusions:

• Multilevel paravertebral block offers effective analgesia for breast cancer surgery.
• The duration of analgesia provided by this block appears to be shorter than previously reported.
