How is pseudocholinesterase deficiency treated?

How is pseudocholinesterase deficiency treated?

  1. Prophylactic transfusion of fresh frozen plasma can augment the patient’s endogenous plasma pseudocholinesterase activity.
  2. Mechanical ventilatory support is the mainstay of treatment until respiratory muscle paralysis spontaneously resolves.

What is pseudo acetylcholinesterase?

Pseudocholinesterase is a serine hydrolase enzyme, primarily produced in the liver that catalyzes the hydrolysis of choline esters, most prominently succinylcholine and mivacurium.[1] It is imperative to differentiate this from “true” cholinesterase, also known as acetylcholinesterase, which occurs in higher …

What causes butyrylcholinesterase deficiency?

Butyrylcholinesterase (BChE) deficiency is a metabolic disorder characterised by prolonged apnoea after the use of certain anaesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anaesthetics.

What drugs should be avoided with pseudocholinesterase deficiency?

The use of succinylcholine, mivacurium and ester local anesthetics must be avoided in patients with pseudocholinesterase deficiency because these patients may not be able to metabolize such anesthetics.

What drugs can cause pseudocholinesterase deficiency?

Pseudocholinesterase deficiency results in delayed metabolism of only a few compounds of clinical significance, including the following: succinylcholine, mivacurium, procaine, and cocaine.

Is Pseudocholinesterase deficiency hereditary?

To have pseudocholinesterase deficiency, you must inherit two affected genes ― one from each of your parents (autosomal recessive inheritance). If you inherit only one affected gene, you won’t have the disorder. But you may process choline esters at a slower rate than people who don’t have an affected gene.

What is AChE and BChE?

Purpose : Acetylcholinesterase (AChE) is the key hydrolytic enzyme of acetylcholine (Ach) in cholinergic synapses. Butyrylcholinesterase (BChE) is a non-specific cholinesterase prominently synthesized in the liver and mainly found in the blood plasma. BChE is also expressed in the nervous system.

What is Bche?

Butyrylcholinesterase (also known as pseudocholinesterase, plasma cholinesterase, BCHE, or BuChE) is a nonspecific cholinesterase enzyme that hydrolyzes many different choline esters [145].
