Local anesthesia (LA) alone or before general anesthesia (GA) significantly reduces postoperative pain in vitrectomy patients. Preoperative LA offers better pain relief than postoperative LA, enhancing patient comfort during vitreoretinal surgery.

Area of Science:

  • Ophthalmology
  • Anesthesiology
  • Surgical Pain Management

Background:

  • Vitrectomies are surgical procedures on the eye.
  • Anesthesia choices include general anesthesia (GA), local anesthesia (LA), or a combination.
  • Local anesthesia is hypothesized to provide superior postoperative pain relief due to its prolonged effect.

Purpose of the Study:

  • To compare postoperative pain levels in patients undergoing vitrectomy.
  • To evaluate the effectiveness of preemptive analgesia using local anesthesia in conjunction with general anesthesia.
  • To determine optimal anesthesia strategies for patient comfort in vitreoretinal surgery.

Main Methods:

  • A study involving 90 patients scheduled for vitrectomy without buckling.
  • Patients were divided into groups receiving GA alone, GA with preoperative LA, GA with postoperative LA, or LA alone.

  • Postoperative pain was assessed using the visual analogue scale.

    • Main Results:

    • Local anesthesia (LA) alone resulted in significantly less postoperative pain compared to general anesthesia (GA) alone (p < 0.0001).
    • Preoperative administration of LA with GA led to lower pain scores than postoperative LA with GA (p < 0.05).
    • Postoperative peribulbar anesthesia combined with GA showed no significant difference in pain compared to GA alone.

    Conclusions:

    • Local anesthesia (LA) alone is effective in managing postoperative pain after vitrectomy.
    • Administering LA preoperatively in combination with general anesthesia (GA) provides superior patient comfort compared to other anesthesia combinations.
    • These findings support the use of LA-based anesthesia strategies for improved outcomes in vitreoretinal surgery.
