Summary
Local surgeons require neuromuscular blockade for strabismus surgery and forced duction tests. A survey revealed many patients may have undergone these procedures with residual muscle tone, impacting surgical conditions.
Area of Science:
- Anesthesiology
- Ophthalmology
- Surgical Procedures
Background:
- Neuromuscular blockade is crucial for specific ophthalmic surgeries.
- Demand for adequate muscle relaxation during strabismus surgery and forced duction testing has increased.
- Current anesthetic practices may not consistently achieve optimal neuromuscular blockade.
Purpose of the Study:
- To review the literature on anesthetic techniques for strabismus surgery.
- To survey regional anesthesiologists regarding their practices.
- To assess the prevalence of suboptimal neuromuscular blockade in strabismus surgery and forced duction testing.
Main Methods:
- A literature review was conducted.
- A questionnaire was distributed to 379 anesthesiologists in the region.
- 264 responses were analyzed to evaluate anesthetic techniques and patient conditions.
Main Results:
- 55% of pediatric patients and 66% of adult patients may have been operated on under suboptimal conditions.
- Residual tone in extraocular muscles was potentially present during forced duction testing.
- Inadequate neuromuscular block may have compromised strabismus correction procedures.
Conclusions:
- Current anesthetic techniques may lead to residual neuromuscular tone during strabismus surgery.
- This can result in suboptimal surgical conditions for both pediatric and adult patients.
- Further investigation and standardization of anesthetic protocols are warranted to ensure adequate muscle relaxation.

01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
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...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
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...

01:24General Anesthesia: Overview
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...

01:22Stages of General Anesthesia
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...
