In early gastric cancer, the aim of surgery is to precisely remove the distal stomach including the primary tumor. To do this, accurate localization of the tumor is crucial, especially in totally laparoscopic surgery. This protocol describes a procedure for intraoperative gastroscopy in totally laparoscopic subtotal gastrectomy.

Varicocele accounts for 35%-40% of infertility cases among men of reproductive age. The international standard treatment method is microscopic varicocelectomy, typically performed under general anesthesia. This study proposes and implements microscopic varicocelectomy under local anesthesia, which provides more humane care for patients and reduces the economic burden.

Local Anesthetics: Clinical Application as Spinal Anesthesia
0 Views •
2023
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...
FAQs
After entering nearby nerves, local anesthetic drugs reversibly block voltage-gated sodium channels. This blockade prevents action potentials from traveling along the nerve toward the brain, interrupting pain transmission from the treated region. Because the block is reversible, the effect is temporary rather than permanent, allowing procedures to proceed without causing lasting loss of nerve function.
Clinicians select the injection site, dose, and technique according to both the procedure and the patient. These choices determine how effectively the intended body region becomes insensitive to pain and help tailor treatment to the area being treated. Matching these factors to the clinical situation supports patient comfort while preserving the targeted nature of the anesthetic effect.
The main distinction is that local anesthesia targets a specific body region without producing loss of consciousness. This can reduce the need for systemic anesthesia, which affects the body more broadly. The approach may also support faster recovery, making it useful when clinicians want pain control for a procedure while maintaining consciousness and limiting systemic anesthetic exposure.
Clinicians monitor patient comfort and vital signs while selecting and applying the injection approach. They also consider the planned procedure and the individual patient when choosing the site, dose, and technique. Combining these technical decisions with ongoing observation allows the care team to evaluate how well the targeted region is responding and whether the procedure remains tolerable.
The overview identifies dentistry, dermatology, obstetrics, and outpatient surgery as important application areas. In each setting, clinicians can select a targeted injection site and anesthetic plan suited to the procedure and patient. These applications show that the approach is not limited to one specialty, but can support different forms of treatment involving localized pain control.
Local anesthesia can support outpatient treatment by avoiding loss of consciousness, reducing the need for systemic anesthesia, and often enabling faster recovery. These features are relevant when a procedure requires pain control in a defined region but does not require the patient to lose consciousness. Clinicians still individualize the injection site, dose, and technique and monitor vital signs and comfort.
