bumetanide, torsemide moa |
- They inhibit theNa+/K+/2Cl− pump in the thick ascending limb of the loop of Henle. - inhibits potassium reabsorption at the thick ascending limb of the loop of Henle. Furosemide ethacrynic acid |

Succinylcholine contraindication. Alternative? |
- Succinylcholine is a depolarizing neuromuscular blocker that can cause life-threatening hyperkalemia. It should not be used in patients with or at high risk for hyperkalemia, such as burn and crush injury patients and patients with prolonged demyelination - GBS. - Non-depolarizing agents such as vecuronium or rocuronium are a better choice in these patients. |

Hypomagnesemia, causes refractory hypokalemia; therefore it is important to correct the magnesium along with the potassium levels to be able to correct the electrolyte abnormalities of such patients. |

- Mild cases can be treated with 5% dextrose in 0.45% saline. - Severe cases should be initially treated with 0.9% saline. |

|
TMP-SMX can cause hyperkalemia and increased Creat. mechanism? |
Trimethoprim can cause hyperkalemia due to blockade of the epithelial sodium channel in the collecting tubule. Trimethoprim also competitively inhibits renal tubular creatinine secretion and may cause an artificial increase in serum creatinine without affecting the glomerular filtration rate. |
|
Agents used to shift potassium intracellularly include..? |
insulin and glucose, sodium bicarbonate, and beta-2 agonists. |
|
A-a gradient in hypoventilation |
normal |
|

Postictal lactic acidosis commonly occurs following a tonic-clonic seizure. It is a transient anion gap metabolic acidosis that resolves without treatment within 60 to 90 minutes following resolution of seizure activity. |
