Summary
A shorter 12.5 mm needle is effective for peribulbar blockade during phacoemulsification surgery. This technique provides adequate analgesia with minimal complications, improving patient safety.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Peribulbar blockade is a common technique for phacoemulsification surgery.
- Potential complications include central spread, globe perforation, and retrobulbar hemorrhage.
- A 25 mm needle is typically used, but a shorter 12.5 mm needle may offer improved safety.
Purpose of the Study:
- To evaluate the efficacy and safety of a 12.5 mm needle for peribulbar blockade in phacoemulsification surgery.
Main Methods:
- A descriptive study involving 200 patients undergoing phacoemulsification.
- Peribulbar blockade administered using a 27 G, 12.5 mm needle inserted inferotemporally.
- Ocular akinesia assessed using a simple akinesia score 10 minutes post-injection.
Main Results:
- 90.5% of patients achieved adequate analgesia after the initial injection.
- 9.5% required supplementary anesthesia.
- No major sight-threatening or life-threatening complications were reported.
Conclusions:
- A 12.5 mm needle is effective for peribulbar blockade in phacoemulsification surgery.
- This technique yields satisfactory results and is a safe alternative.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:19Depolarizing Blockers: Pharmocokinetics
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
