Clinical experience with the peribulbar block for ophthalmologic surgery
1Department of Anesthesiology, Northwestern University Medical School, Chicago, Illinois 60611.
Background And Objectives:
The peribulbar block is a safe and reliable alternative to the retrobulbar block. In this clinical report, we describe the anatomy of the orbit and the technique involved in performing the block.
Methods:
The technique is not new, and modifications from the original paper by Mandel and Davis are few but significant. Complications include peribulbar hemorrhage, perforation of the globe and intravascular injection.
Results:
In our experience of 2600 peribulbar blocks, we have seen five patients with minor peribulbar hemorrhage.
Conclusions:
Supplementation of the block was required in 3% of the patients.
Insights
The peribulbar block offers a safe alternative to retrobulbar block for ophthalmic anesthesia. With 2600 procedures, minor complications were rare, with 3% requiring supplemental anesthesia.
Area of Science:
- Ophthalmology
- Anesthesiology
- Surgical Anatomy
Background:
- Peribulbar block is presented as a safe and reliable alternative to retrobulbar block.
- This clinical report details the orbital anatomy and technique for performing the peribulbar block.
Purpose of the Study:
- To describe the anatomy of the orbit relevant to peribulbar block.
- To outline the technique for performing the peribulbar block.
- To report on the safety and efficacy of the peribulbar block.
Main Methods:
- Review of orbital anatomy pertinent to peribulbar anesthesia.
- Description of the modified peribulbar block technique.
- Analysis of complications and supplementation rates from clinical experience.
Main Results:
- A total of 2600 peribulbar blocks were performed.
- Five cases (0.19%) of minor peribulbar hemorrhage were observed.
- Supplementation of anesthesia was necessary in 3% of patients.
Conclusions:
- Peribulbar block is a safe and effective technique for ophthalmic anesthesia.
- The reported complication rate, including hemorrhage, is low.
- A small percentage of patients may require supplemental anesthesia for adequate block.
