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.

Optimum Nutrition is important for maintanence of health. Make sure you are eating a healthy diet!

Here are sites where you can find:

All the nutrients in almost any food.

Sodium Intake should be kept below 2 grams daily for HypoKPP patients.

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.

Patient Medical Information Template in Spanish

Our Spanish-speaking patients may access the Spanish language Medical Information Template. It is in Open Document Format, so patients can add their own information to the template. Thanks to Barbara Baker and friends for translating our Patient's Information Sheet for us.

Leaky Channels make weak muscles

Leaky channels make weak muscles: Mutations in the skeletal muscle voltage-gated calcium channel (CaV 1.1) have been associated with hypokalemic periodic paralysis, but how these mutations cause the symptoms of the disorder has always been unclear. In this article the authors describe how they used mice with the CaV 1.1 mutation  to investigate how the mutation causes the features of HypoKPP.

Abstract

The Action Potential - A Movie!

Puzzled by the terms membrane potential, sodium channel, potassium channel and sodium-potassium pump?  

This cute cartoon explains what each is and shows how the potassium and sodium channels, and the sodium potassium pump maintain muscle membrane potential.  Although this uses nerves to illustrate how the principle works, the action is the same in muscle membrane. Click here to watch.
