Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

1.5K
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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

788
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...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

1.5K
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.
One of the advantages of...

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

2.1K
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...

Clinical Applications of Epidermal Stem Cells

3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Local Anesthetics: Common Agents and Their Applications

992
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...

    Summary

    Local rotation plasty is an effective surgical technique for treating body surface defects. This study analyzed 54 cases, finding a low complication rate, particularly with rotation angles under 90 degrees.

    Area of Science:

    • Plastic Surgery
    • Surgical Oncology

    Background:

    • Local rotation plasty is a recognized method for treating body surface defects.
    • Recent literature suggests exploring new theoretical applications for this technique.

    Purpose of the Study:

    • To conduct a clinical analysis of local plasty application across various anatomical regions.
    • To evaluate the efficacy and outcomes of local rotation plasty in oncological and non-oncological cases.

    Main Methods:

    • Retrospective study of 54 consecutive local plasty surgical cases.
    • Data collected between January 2010 and January 2015.
    • Analysis included patient demographics, rotation angles, and postoperative complications.

    Main Results:

  • A total of 54 patients (39 male, 15 female) were analyzed, with a median age of 62.5 (male) and 57.5 (female).
  • Rotation angles of 90° were used in 24.07% of cases, while angles <90° were used in 75.93%.
  • Postoperative complications occurred in 9.26% ±4.25% of cases, primarily in the higher rotation angle group, and were managed conservatively without reconstructive failure.

    • Conclusions:

    • Local rotation plasty is a safe and effective reconstructive option for body surface defects.
    • Lower rotation angles (<90°) may be associated with fewer complications.
    • Further research into new applications of local plasty is warranted.
