Area of Science:

  • Anesthesiology
  • Pharmacology

Background:

  • Homologous blood transfusions carry risks like transfusion reactions and infectious disease transmission.
  • Minimizing intraoperative blood loss is crucial to avoid allogeneic transfusions.

Purpose of the Study:

  • To review various pharmacologic agents used for inducing controlled hypotension.
  • To provide clinicians with an overview of drug options for blood loss management.

Main Methods:

  • Review of literature on drugs used for controlled hypotension.
  • Categorization of drugs including inhalational anesthetics, vasodilators, beta-blockers, and calcium channel blockers.

Main Results:

  • Multiple drug classes are available for controlled hypotension.
  • Agents include nitroglycerin, nitroprusside, and various anesthetic agents.

Conclusions:

  • Controlled hypotension is a valuable strategy to reduce homologous transfusion needs.
  • Clinicians have diverse pharmacologic options for managing intraoperative blood loss.
