Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

591
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...

General Anesthesia: Overview01:24

General Anesthesia: Overview

196
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 Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

421
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 Surface, Infiltration, and Conduction Block Anesthesia01:30

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

987
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

57
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

376
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...

Summary

Nonoperating room anesthesia (NORA) poses unique risks, with higher malpractice claims and complications like airway issues and aspiration pneumonitis compared to operating rooms. Enhanced patient selection, monitoring, and preparedness are crucial for NORA safety.

Area of Science:

  • Anesthesiology
  • Patient Safety
  • Medical Risk Management

Background:

  • Nonoperating room anesthesia (NORA) is expanding due to technological advancements enabling procedures outside traditional operating rooms.
  • NORA environments present unique challenges including patient complexity, rapid turnover, and varying team familiarity.
  • Limited emergency preparedness in NORA settings requires focused attention.

Purpose of the Study:

  • To analyze risks associated with nonoperating room anesthesia (NORA) procedures.
  • To identify common complications and contributing factors in NORA settings.
  • To review strategies for effective risk reduction in NORA.

Main Methods:

  • Analysis of closed claims data to identify malpractice claims in NORA.
  • Review of studies on complications in NORA compared to operating room cases.
  • Evaluation of risk reduction strategies and safety guidelines.

Main Results:

  • Malpractice claims in NORA are less frequent overall but occur at a higher incidence than in operating rooms.
  • Common NORA complications include airway management failures, respiratory depression, and aspiration pneumonitis.
  • Cardiovascular instability is prevalent in high-risk NORA procedures, especially in cardiology and radiology.

Conclusions:

  • Effective risk reduction in NORA necessitates meticulous patient selection and strict adherence to safety protocols.
  • Enhanced preoperative screening, emergency preparedness, and advanced airway tools can mitigate NORA complications.
  • Site-specific checklists, improved interdisciplinary communication, and advanced monitoring technologies are vital for NORA patient safety.
