General Anesthesia: Overview01:24

General Anesthesia: Overview

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...
Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

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.

Local Anesthetics: Clinical Application as Spinal Anesthesia

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...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Area of Science:

  • Anesthesiology
  • Transplant Surgery
  • Hepatology

Background:

  • Orthotopic liver transplantation is the definitive treatment for end-stage liver disease, with over 6000 US procedures annually.
  • Increasing prevalence of steatohepatitis leads to older, more comorbid transplant candidates.
  • Donor organ shortage necessitates strategies to expand the donor pool.

Purpose of the Study:

  • To highlight the critical role of transplant anesthesiologists in managing complex liver transplant patients.
  • To discuss anesthetic considerations across different surgical phases and patient comorbidities.
  • To review current trends in perioperative care for liver transplantation.

Main Methods:

  • Preoperative assessment of cardiovascular, respiratory, renal, neurological, and gastroenterological comorbidities.
  • Intraoperative management focusing on hemodynamic stability, coagulopathy, and metabolic disturbances.
  • Postoperative care including "fast-track" extubation and management of specific conditions like fulminant hepatic failure.

Main Results:

  • Liver transplant surgery involves distinct phases (preanhepatic, anhepatic, reperfusion) with unique anesthetic challenges.
  • Understanding vascular exclusion techniques and venovenous bypass is crucial for anesthesiologists.
  • Management of comorbidities like coronary artery disease and portopulmonary hypertension remains complex and program-dependent.

Conclusions:

  • Anesthesiologists are integral to successful liver transplantation outcomes.
  • Perioperative care innovations, including antifibrinolytics and point-of-care testing, are improving patient management.
  • Specialized considerations are required for patients with fulminant hepatic failure or those receiving split-liver grafts.
