The continuous-injection technique to reduce complications during retrobulbar anesthesia

Area of Science:

• Ophthalmology
• Anesthesia

Background:

• Retrobulbar and peribulbar anesthesia are standard procedures for ophthalmic surgery.
• These techniques carry inherent risks, including retrobulbar hemorrhage and globe perforation, which can lead to vision loss.

Purpose of the Study:

• To introduce and evaluate a continuous injection technique for retrobulbar and peribulbar anesthesia.
• To demonstrate how this technique mitigates known risks associated with traditional methods.

Main Methods:

• A continuous injection method was employed during needle advancement for anesthesia administration.
• The technique involves injecting anesthetic agent while the needle is advanced into the retrobulbar or peribulbar space.
• Immediate feedback on needle contact with the sclera is provided by plunger resistance.

Main Results:

• The continuous injection technique was observed to reduce the incidence of retrobulbar hemorrhage.
• Early detection of needle-sclera contact prevents globe perforation by providing tactile resistance.
• This method enhances safety in both retrobulbar and peribulbar anesthesia procedures.

Conclusions:

• The continuous injection technique offers a safer alternative for retrobulbar and peribulbar anesthesia.
• This method effectively minimizes the risk of blinding complications during ophthalmic procedures.
• Ophthalmologists can benefit from this technique to improve patient safety and outcomes.
