Summary
Advanced subconjunctival anesthesia (ASCAN) provides effective pain relief and immobility for cataract surgery. This minimally invasive technique offers a safe alternative to traditional ocular blocks, ensuring patient comfort and surgical success.
Area of Science:
- Ophthalmology
- Anesthesiology
Background:
- Ocular regional blocks carry risks due to blind posterior orbit instrumentation.
- Topical anesthesia is insufficient for controlling eye and lid movements during surgery.
Purpose of the Study:
- To evaluate the efficacy and safety of Advanced Subconjunctival Anesthesia (ASCAN) for phacoemulsification surgery.
- To assess pain control and ocular akinesia achieved with ASCAN.
Main Methods:
- A nonrandomized case series of 60 adult patients undergoing phacoemulsification.
- ASCAN involved injecting local anesthetic into the sub-Tenon's space using a visually guided technique.
- Ocular motor function and pain were assessed post-injection.
Main Results:
- All 60 patients completed surgery without supplemental anesthesia.
- 97% of patients reported no pain, with 2 experiencing mild, transient discomfort.
- Adequate globe akinesia and lid paralysis were achieved, comparable to other methods, with no major complications.
Conclusions:
- Advanced Subconjunctival Anesthesia (ASCAN) is a safe and effective visually guided technique.
- ASCAN provides satisfactory analgesia and akinesia for phacoemulsification surgery.
- This method minimizes risks associated with traditional ocular blocks.

01:24General Anesthesia: Overview
673
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

00:56Extraction: Advanced Methods
1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.4K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
