There are four main types of episiotomy: 1  Medio-lateral: The incision is made downward and outward from the midpoint of the fourchette either to the right or left. 2  It is directed diagonally in a straight line which runs about 2.5 cm (1 in) away from the anus (midpoint between the anus and the ischial tuberosity).
Technically, hyperkalemia means an abnormally elevated level of potassium in the blood. The normal potassium level in the blood is 3.5-5.0 milliequivalents per liter (mEq/L). Potassium levels between 5.1 mEq/L to 6.0 mEq/L reflect mild hyperkalemia.
The body needs potassium for nerve and muscle cells to function, but too much potassium can also interfere with function (see Overview of Potassium). The most common cause of mild hyperkalemia is the use of drugs that decrease blood flow to the kidneys or prevent the kidneys from excreting normal amounts of potassium. Kidney failure can cause severe hyperkalemia on its own. Addison disease can also cause hyperkalemia.
