Intercostal nerve block (ICNB) provides superior postoperative pain relief for breast surgery compared to general anesthesia. Regional anesthesia also resulted in fewer side effects like nausea and vomiting.

Area of Science:

  • Anesthesiology
  • Surgical Procedures
  • Pharmacology

Background:

  • Minor breast surgeries often involve pain and stress.
  • General anesthesia and intercostal nerve block (ICNB) are common anesthetic options.
  • Vasoconstrictors like epinephrine and ornipressin are used in local anesthetics.

Purpose of the Study:

  • Compare the efficacy of ICNB versus general anesthesia for breast surgery.
  • Evaluate surgical stress and postoperative analgesia between anesthetic methods.
  • Assess the impact of epinephrine and ornipressin as vasoconstrictors in ICNB.

Main Methods:

  • 45 female patients undergoing minor breast surgery were divided into three groups.
  • Group A (15 patients): ICNB with lidocaine plus epinephrine.

  • Group B (15 patients): ICNB with lidocaine plus ornipressin.
  • Control group (15 patients): General anesthesia.

    • Main Results:

    • Higher lidocaine plasma levels observed in the ornipressin group (Group B) compared to the epinephrine group (Group A).
    • Elevated epinephrine and norepinephrine plasma levels during surgery in the epinephrine group.
    • Postoperatively, general anesthesia patients had the highest catecholamine levels.
    • General anesthesia group reported significantly more nausea and vomiting.
    • Regional anesthesia groups required significantly less postoperative analgesia.

    Conclusions:

    • Intercostal nerve block offers effective anesthesia for minor breast surgery.
    • Regional anesthesia leads to reduced postoperative pain and fewer side effects compared to general anesthesia.
    • Ornipressin may lead to higher lidocaine absorption than epinephrine.
