Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

1.1K
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...

Inhalational Anesthetics: Overview

934
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Local Anesthetics: Clinical Application as Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

658
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 Spinal Anesthesia

1.2K
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...

Nurses' Legal Responsibilities I01:27

Nurses' Legal Responsibilities I

1.3K
In healthcare, informed consent is a crucial process that involves thoroughly communicating medical treatment options to patients, including benefits, risks, potential side effects, and alternatives. This process enables patients to make well-informed decisions about their care, ensuring they understand the implications of their choices before consenting to or refusing treatment.
The legal responsibilities of a nurse regarding informed consent include the following:

Area of Science:

  • Medical Education
  • Nursing Practice
  • Information Science

Background:

  • The National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA) develops examination questions based on clinically relevant resources.
  • Understanding current reference material usage among nurse anesthetists is crucial for ensuring the applicability of examination content.

Purpose of the Study:

  • To investigate the reference resources utilized by Certified Registered Nurse Anesthetists (CRNAs) in their clinical practice.
  • To inform the NBCRNA's selection of resources for developing future examination questions.

Main Methods:

  • A survey was distributed electronically in October 2016 to a random selection of 14,993 student and CRNAs.
  • A total of 3,155 responses were analyzed, yielding a final response rate of 21.0%.

Main Results:

  • Web-based references were used by 90.7% of respondents, significantly more than textbooks (61.4%) or journals (62.3%).
  • Respondents reported more frequent use of web-based resources compared to textbooks.
  • Key characteristics of preferred references included accessibility, portability, and reputation.

Conclusions:

  • Practicing nurse anesthetists predominantly favor web-based resources over traditional print formats like textbooks and journals.
  • This preference for digital resources is consistent across various age groups and professional roles within nurse anesthesia.
  • Findings support aligning NBCRNA examination content with frequently used, accessible, and reputable web-based clinical resources.
