How much blood loss in a child is considered serious?

In general, a healthy child does not require transfusion unless the hematocrit has fallen to the 20-25 range for an infant, or 20 for a child….Maximum allowable blood loss.

Age Circulating blood volume (ml/kg)
Full term neonate 80 – 90
Infant 70 – 80
Child 70- 75
Obese child 60 – 65

What is considered too much blood loss?

When blood loss nears 30 to 40 percent of total blood volume, your body will have a traumatic reaction. Your blood pressure will drop down even further, and your heart rate will further increase. You may show signs of obvious confusion or disorientation. Your breathing will be more rapid and shallow.

How much blood loss is considered a hemorrhage?

Traditionally, postpartum hemorrhage (PPH) has been defined as greater than 500 mL estimated blood loss associated with vaginal delivery or greater than 1000 mL estimated blood loss associated with cesarean delivery.

How is excessive blood loss treated?

Medical therapy for menorrhagia may include:

  1. Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs, such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve), help reduce menstrual blood loss.
  2. Tranexamic acid.
  3. Oral contraceptives.
  4. Oral progesterone.
  5. Hormonal IUD (Liletta, Mirena).

Why is child blood loss important?

In addition to the decrease in intravascular volume and its impairment on stroke volume, the loss of red blood cells significantly reduces oxygen delivery to the tissues. Additionally, hemorrhagic shock and resuscitation may result in the development of a systemic inflammatory state.

Why is blood loss in children worse than adults?

The higher metabolic rate results in greater consumption of oxygen and other metabolites, and for this reason, higher respiratory and heart rates. The larger surface-area to body-mass ratio results in greater heat loss for infants and children.

What are the effects of blood loss?

When blood loss is rapid, blood pressure falls, and people may be dizzy. When blood loss occurs gradually, people may be tired, short of breath, and pale. Stool, urine, and imaging tests may be needed to determine the source of bleeding.

What causes loss of blood in the body?

Blood loss can be acute and rapid or chronic. Some causes of rapid blood loss include surgery, childbirth, and trauma. Chronic blood loss is more often responsible for anemia. It can result from a stomach ulcer, cancer, or another type of tumor.

Is PPH life threatening?

With PPH, you can lose much more blood, which is what makes it a dangerous condition. PPH can cause a severe drop in blood pressure. If not treated quickly, this can lead to shock and death.

Will PPH happen again?

If you have had a previous birth that was complicated by a primary PPH, there is an increased risk of PPH in future pregnancies – 1 in 10 women will have a PPH again in a future pregnancy.

What is an early indication of ongoing blood loss?

During the earliest stage of hypovolemic shock, a person loses less than 20% of their blood volume. This stage can be difficult to diagnose because blood pressure and breathing will still be normal. The most noticeable symptom at this stage is skin that appears pale. The person may also experience sudden anxiety.

Why do children have a higher blood volume?

1. Despite a smaller stature, burned children have a greater body surface area per mass than adults. 2. Cardiac function, mean blood volume, and normal hemoglobin levels are age-dependent in children; hence, children have a higher blood transfusion/unit volume ratio.
