Insights

Rapid blood transfusions cause prolonged hypocalcaemia in liver disease patients. Impaired liver function exacerbates this condition, impacting cardiovascular health during liver transplantation.

Area of Science:

  • Anesthesiology
  • Hepatology
  • Critical Care Medicine

Background:

  • Massive transfusion-related hypocalcaemia poses significant cardiovascular risks.
  • End-stage liver disease patients undergoing liver transplantation are particularly vulnerable.

Purpose of the Study:

  • To compare the severity and duration of ionized hypocalcaemia between patients with normal and impaired liver function following rapid blood transfusion.

Main Methods:

  • Patients were divided into three groups: liver transplant (LT), spinal surgery (SP), and saline control (SN).
  • Ionized calcium levels were measured before and at multiple time points after transfusion with packed red blood cells (PRBCs) or saline.

Main Results:

  • PRBC transfusion induced more severe hypocalcaemia than saline.
  • Hypocalcaemia resolved faster in patients with normal liver function (group SP) compared to those with liver dysfunction (group LP).
  • Persistent hypocalcaemia at 60 minutes correlated with vital signs and metabolic markers.

Conclusions:

  • Rapid blood transfusion leads to more severe and prolonged ionized hypocalcaemia in patients with liver dysfunction.
  • This highlights a critical concern for liver transplant recipients receiving massive transfusions.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
Ionic Bonds00:42

Ionic Bonds

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...
