General Anesthesia: Overview01:24

General Anesthesia: Overview

198
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...

Inhalational Anesthetics: Overview

230
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...

Area of Science:

  • Anesthesiology
  • Thoracic Surgery
  • Critical Care Medicine

Background:

  • Large mediastinal masses can cause acute hemodynamic or respiratory decompensation during anesthesia.
  • Evidence regarding risks, mechanisms, and interventions for anesthesia in these patients is limited.
  • A comprehensive review is necessary to define risks and guide clinical practice.

Purpose of the Study:

  • To systematically review evidence on anesthesia risks associated with large mediastinal masses.
  • To identify mechanisms of potential decompensation.
  • To outline preventative and reactive interventions for anesthetic management.

Main Methods:

  • Systematic review of the PubMed database for studies involving adults with large mediastinal masses undergoing anesthesia.
  • Inclusion of all publication types providing data on risks, mechanisms, or management techniques.
  • Synthesis of evidence based on consensus judgment due to the nature of included studies (case reports, small series).

Main Results:

  • A risk stratification system (low, moderate, high, very-high) was developed based on symptoms, mass/chest ratio, and compression.
  • This categorization aids in tailoring pre-anesthetic preparation, from minimal to extensive.
  • Assessing physiologic impact of compression provides a framework for anesthetic management and contingency planning.

Conclusions:

  • A practical framework for managing patients with large mediastinal masses requiring anesthesia has been established.
  • This framework streamlines preparation and management in a rational manner.
  • Despite evidence limitations, the developed approach addresses this uncommon but serious clinical scenario.
