Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

425
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.

Local Anesthetics: Clinical Application as Spinal Anesthesia

636
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 Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

434
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...

General Anesthesia: Overview01:24

General Anesthesia: Overview

220
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...

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

1.1K
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...

Area of Science:

  • Anesthesiology
  • Geriatric Surgery
  • Orthopedic Surgery

Background:

  • Hip fracture surgery poses significant physiological stress, particularly for elderly and frail patients.
  • Anesthesia selection is critical for managing perioperative morbidity and mortality in this population.

Purpose of the Study:

  • To review benefits, risks, and contraindications of traditional and novel anesthesia for hip fracture surgery.
  • To describe the impact of various anesthesia approaches on postoperative outcomes.

Main Methods:

  • Review of general anesthesia, spinal anesthesia, and peripheral nerve block techniques.
  • Analysis of novel local anesthesia approaches and their comparison to traditional methods.

Main Results:

  • Novel local anesthesia may offer advantages by minimizing induction time and reducing respiratory suppression.
  • These newer techniques potentially decrease short- and long-term cognitive effects.
  • Newer anesthesia methods may reduce morbidity and mortality, especially in high-risk surgical patients.

Conclusions:

  • Anesthesia choice significantly influences outcomes in hip fracture surgery.
  • Novel local anesthesia techniques show promise in improving patient safety and recovery.
  • Further research into advanced anesthesia modalities is warranted for frail patient populations.
