General Anesthesia: Overview01:24

General Anesthesia: Overview

879
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 Spinal Anesthesia

1.6K
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

872
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...

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

820
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

1.6K
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...

Area of Science:

  • Anesthesiology
  • Surgical Patient Care
  • Health Psychology

Background:

  • Preoperative anxiety can negatively impact surgical outcomes.
  • Effective management of patient anxiety is crucial for successful surgical procedures.

Purpose of the Study:

  • To investigate the impact of information seeking on preoperative anxiety in surgical patients.
  • To identify factors influencing patient anxiety before surgery.

Main Methods:

  • Prospective, multicentered survey of 330 patients undergoing spinal anesthesia.
  • Utilized State-Trait Anxiety Inventory Scale-State (STAI-S) and Amsterdam Preoperative Anxiety and Information Scale.
  • Statistical analysis included ANOVA, Kruskal-Wallis, Student's t-test, Chi-square, and Fisher's exact tests.

Main Results:

  • University graduates reported lower anxiety levels.
  • Internet information seeking significantly reduced surgical anxiety (P < 0.05) but not anesthesia-related anxiety.
  • Patients seeking information exhibited higher information desire (P < 0.05).

Conclusions:

  • Information seeking correlates with reduced preoperative surgical anxiety.
  • High information desire persists even after seeking information.
  • Validated multimedia information resources may help alleviate anxiety and information needs.
