Area of Science:

  • Ophthalmology
  • Anesthesiology
  • Surgical Anesthesia

Background:

  • Peribulbar block is a common technique for ophthalmic anesthesia.
  • Assessing the efficacy and safety of this block in a district general hospital setting is crucial for standardizing practice.
  • Pain during peribulbar block administration can be a limiting factor.

Purpose of the Study:

  • To evaluate the efficacy and safety of peribulbar blocks performed by anesthesiologists in a District General Hospital.
  • To determine the impact of a 'painless local' subconjunctival injection on the pain associated with peribulbar block administration.

Main Methods:

  • An audit of 1000 consecutive patients receiving peribulbar blocks with 2% lignocaine.
  • Efficacy assessment included visual rating scores for operative pain, eye movement, intraocular pressure, and reinjection rates.
  • Safety was evaluated by monitoring complications; pain scores were compared using the Mann-Whitney U-test to assess the 'painless local' injection effect.

Main Results:

  • Successful akinesia was achieved in 79% of cases with very low operative pain scores (median = 0).
  • All recorded complications were minor, with no sight- or life-threatening events.
  • The 'painless local' injection (administered to 499 patients) significantly reduced pain scores during block administration (p<0.05).

Conclusions:

  • Peribulbar block is a safe and effective anesthesia for eye surgery when performed by experienced staff with methodical training.
  • The 'painless local' subconjunctival injection is effective in mitigating the pain associated with peribulbar block administration.
  • These findings support the routine use of peribulbar blocks and the 'painless local' technique in ophthalmic anesthesia.
