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 are metabolized by pseudocholinesterase?
Neuromuscular Blocking Drugs Butyrylcholinesterase (BChE) or pseudocholinesterase is the enzyme that hydrolyzes neuromuscular blocking agents such as succinylcholine and mivacurium, as well as ester local anesthetic agents.
Can pseudocholinesterase deficiency be prevented?
Pseudocholinesterase deficiency can be caused by a genetic defect (mutation) that either is inherited or is acquired due to illness, injury or certain medications. There is no cure for pseudocholinesterase deficiency.
Is rocuronium safe in pseudocholinesterase deficiency?
However, with the current availability of sugammadex as a reversal agent, rocuronium has become a viable alternative to produce similar conditions with fewer side effects and avoid prolonged ventilation in patients with pseudocholinesterase deficiency.
How is Pseudocholinesterase deficiency treated?
There is no cure for pseudocholinesterase deficiency. If you have the condition and you receive muscle relaxants that prolong your anesthesia recovery, you’ll likely need medical assistance. If needed, mechanical ventilation support and sedation are provided while you recover and start breathing on your own.
How do you reverse succinylcholine?
Sugammadex can reverse profound blockade and can be given for immediate reversal and its use would avoid the potentially serious adverse effects of the currently used agent, succinylcholine. Also, sugammadex can reverse NMB more quickly and predictably than existing agents.
Which local anesthetic is metabolized by pseudocholinesterase?
Ester local anesthetics are predominantly metabolized by pseudocholinesterase.
How do you treat Pseudocholinesterase deficiency?
Do dentists use succinylcholine?
Succinylcholine is well known in oral and maxillofacial surgeon and dentist anesthesiologist practices, and it has a long history of successful use.
How long does it take for succinylcholine to wear off?
Succinylcholine has been traditionally used as a first-line paralytic due to its quick onset of action and short half-life. Succinylcholine’s duration of action is 10—15 minutes, whereas the half-life of rocuronium is anywhere from 30—90 minutes, depending on the dose.
How do you treat succinylcholine?
Intermittent IV injections of succinylcholine may also be used to provide muscle relaxation for long procedures. An IV injection of 0.3 to 1.1 mg/kg may be given initially, followed, at appropriate intervals, by further injections of 0.04 to 0.07 mg/kg to maintain the degree of relaxation required.
How is pseudocholinesterase deficiency diagnosed?
Diagnosis Diagnosis. Pseudocholinesterase deficiency often is first suspected after an episode of prolonged respiratory paralysis following general anesthesia. The diagnosis is confirmed by a blood test that measures pseudocholinesterase enzyme activity.
How is pseudocholinesterase deficiency treated?
Diagnosis. Pseudocholinesterase deficiency may be suspected when you have problems recovering muscle control and breathing after receiving the muscle relaxant succinylcholine or mivacurium as part of anesthesia.
Is pseudocholinesterase deficiency hereditary?
Pseudocholinesterase deficiency is inherited as an autosomal recessive trait. The faulty gene is located on chromosome 3 (3q26.1-q26.2). Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.
