Hypokalemic Periodic Paralysis

Hypokalemic periodic paralysis (HypoKPP) is one of the primary forms of periodic paralysis, caused by one or more mutations in the calcium, sodium or potassium ion channels in muscle membrane.

Features of Hypokalemic Periodic Paralysis

There are two forms of HypoKPP, a paralytic form and a myopathic form.

Summary

Anaesthesia and peri-operative care in the primary Periodic Paralysis Disorders

Adverse reactions to anaesthesia, including life-threatening events, are a serious concern for patients with Periodic Paralysis Disorders. Many of our patients report serious events associated with anesthesia and side effects which may linger for days to months.

There is rarely time for a surgical team to comb through journals and texts for the specialized knowledge needed to care for the patient with periodic paralysis.

The Use of Bactrim in the Periodic Paralyses

The antibiotic Bactrim is well-known to produce muscle weakness, even paralysis in patients with Hypokalemic Periodic Paralysis.

Long-time exercise test in the diagnosis of periodic paralysis

Ding Z, Liu M, Cui L. Reference value of long-time exercise test in the diagnosis of primary periodic paralysis. Chin Med J (Engl). 2014;127(18):3219-23.

Abstract

BACKGROUND:
The long-time exercise test (ET) is used to diagnose the primary periodic paralyses (PPs). However the reference values of ET are many and various. This study aimed to investigate the reference value of long-time ET in the diagnosis of PPs.

Abstract

Mutations of the skeletal muscle voltage-gated sodium channel (NaV1.4) are an established cause of several clinically distinct forms of periodic paralysis and myotonia. Focal paresis has sometimes already been described. We report a case with atypical clinical manifestation comprising paramyotonia and cold-induced persistent and focal paralysis.

Akut behandling af et hypokalemisk paralytisk anfald

Akut behandling af et hypokalemisk paralytisk anfald

Første skridt:
1. Åndedræts- eller hjerteanfald er mulige
2. Tjek hjerte og vejrtrækning - dilatation i hjertet kan forårsage høj puls og lavt blodtryk.
3. Foretag måling af hjerterytme/EKG.
4. Mål elektrolytter for at bestemme serum K+
5. Giv ilt - blodprøve fra fingeren afspejler måske ikke iltmætningen pga. dilatation
6. Anbring patienten som ved koma for at undgå kvælning.
