Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

561
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

400
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 Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

332
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

908
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...

Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

378
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Analgesia and Pain Management01:25

Analgesia and Pain Management

403
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Area of Science:

  • Orthopedic Surgery
  • Pain Management
  • Anesthesiology

Background:

  • Patient anxiety regarding local anesthetic injection pain is common during Wide Awake Local Anesthesia No Tourniquet (WALANT) carpal tunnel surgery.
  • Minimally painful injection techniques are not consistently prioritized, leading to unnecessary patient discomfort.
  • Objective measurement of injection pain is needed to improve surgical technique.

Purpose of the Study:

  • To assess the impact of direct patient feedback on a surgeon's local anesthetic injection pain events during WALANT carpal tunnel surgery.
  • To develop an objective scoring system for injection pain to enhance surgeon skill.

Main Methods:

  • A single surgeon collected feedback from 250 consecutive patients undergoing WALANT carpal tunnel surgery.
  • Patients reported pain events during local anesthetic injection.
  • Pain events were counted over 35 months to objectively score injection technique.

Main Results:

  • The surgeon's injection pain score demonstrated significant improvement over the study period.
  • A 'hole-in-one' score (only feeling the initial needle prick) increased from 0 in the first 50 patients to 37 in the last 50.
  • This indicates a dramatic reduction in perceived injection pain.

Conclusions:

  • Surgeons performing WALANT carpal tunnel surgery can effectively reduce injection pain by soliciting patient feedback on pain events.
  • Counting patient-reported pain events provides a quantifiable score for injection technique.
  • Immediate patient feedback serves as a valuable tool for surgeons to refine and minimize injection-related pain.
