What is the result of metabolic acidosis if pyloric stenosis?

What is the result of metabolic acidosis if pyloric stenosis?

Bowel obstruction : Then vomiting, dehydration and loss of electrolytes. Gastric contents lost as vomit include acids, leading to a metabolic alkalosis (a 'contraction' alkalosis) with hypokalemia (low potassium), the baby needs to be admitted to a hospital, have intravenous fluids, a surgical consult and surgical repair of the pylorus to relieve the stenosis. It can be performed open or laprascopic. ...Read more

Metabolic Acidosis (Definition)

Metabolic acidosis occurs either from primary acid retention, renal (kidney) dysfunction/failure or bicarbonate (sodium bicarbonate) losses. Primary acid retentions cause anion-gap metabolic acidosis from these etiologies (methanol, uremia, diabetic ketoacidosis, para-aldehyde, isoniazid, lactic acidosis, ethylene glycol, salicylates). Kidney's dysfunction leads to acidosis. Finally any loss ...Read more

What is the chance of a new child having pyloric stenosis?

Gender/Race involved: Hypertrophic pyloric stenosis (hps) is more common in boy babies & white babies. There is a 1 in 300 chance of a white baby boy developing hps. It is 5 times more common in boys than girls & 5 times more common in whites than blacks. Therefore, it is most commonly seen in white baby boys & least commonly seen in black baby girls. ...Read more

Should i be worried if i had pyloric stenosis when i was little?

Should i be worried if i had pyloric stenosis when i was little?

Probably not: Hypertrophic pyloric stenosis (HPS) affects babies in the first few weeks of life. After surgical correction with pyloromyotomy, babies are basically normal. They can feed fine, and the stomach empties fine. It would be very unusual for a middle-aged adult to have problems referable to having had HPS as a baby. ...Read more

What are values that correspond with the diagnosis of pyloric stenosis?

What are values that correspond with the diagnosis of pyloric stenosis?

Several: Most values are usually of a chemical or electrolyte nature. Vomiting causes losses of chloride, potassium. Hypokalemic, hypochloremia are the classis values when a blood assay is done. ...Read more

Can dehydration lead to metabolic acidosis?

It usually does: The contraction of the fluid volume caused by dehydration routinely leads to a metabolic acidosis as the metabolism begins to shift to more fat breakdown & those byproducts add to the acidity of the blood.Fluid expansion through oral or IV re-hydration can correct this quickly by exposing the blood to buffer compounds in the tissues. ...Read more

Is it possible for pyloric stenosis to 'come back'?

Is it possible for pyloric stenosis to 'come back'?

Usually not: Hypertrophic pyloric stenosis (hps) in a young baby is treated with an operation called a pyloromyotomy. The hypertrophic circular pyloric muscle fibers are split to open the pylorus & allow the stomach to empty. If done well & thoroughly, hps should not return. One occasionally hears of a case of recurrent hps, but often, when looked at closely, it was an inadequate pyloromyotomy to begin with. ...Read more

How can metabolic acidosis cause kussmaul breathing?

How can metabolic acidosis cause kussmaul breathing?

Yes.: Kussmaul breathing is a deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also renal failure. It is a form of hyperventilation, which is any breathing pattern that reduces carbon dioxide in the blood due to increased rate or depth of respiration. In metabolic acidosis, breathing is first rapid and shallow. ...Read more

What is the difference between pyloric stenosis and hypertrophic pyloric stenosis?

What is the difference between pyloric stenosis and hypertrophic pyloric stenosis?

Same entity: Some use the optional discriptor "hypertrophic" as an add on to pyloric stenosis. Ps is by caused by an overgrowth and tightening of the muscles surrounding the pyloric region of the small intestine. As such the "hypertrophic" is a redundant term. Some do a similar thing by saying yellow jaundicde when jaundice would be sufficient. ...Read more

Acidosis (Definition)

Normally our body chemistry is kept in a narrow range, and in particular the amount of acid in the body is kept within a narrow range. The amount of acid is measured by a value called the ph. It is normally a value between 7.35 and 7.45, values below 7.35 are considered to be "acidotic" a patient with this value of the blood chemistry ...Read more


Pyloric Stenosis (Definition)

Pyloric stenosis is when the pyloric muscle thickens and closes off the outlet to the stomach. This causes vomiting which lead to dehydration. Happens usually between 2-8 weeks of age. ...Read more
