Neonatal Resuscitation Guide

- Neonatal Shock

Shock is a serious and acute condition of circulatory failure and insufficient oxygen to meet the needs of the neonate's tissues and vital organs. This deficiency may result from blood loss, weak heart muscle, or septicemia, causing cells to rely on anaerobic metabolism for energy, which leads to increased blood acidity.

Causes:

• Hemorrhage and significant blood loss, either before birth (e.g., placental abruption) or after birth (e.g., coagulation disorders, severe pulmonary hemorrhage).
• Neonatal asphyxia
• Bacterial contamination of the amniotic fluid and severe septicemia
• Congenital heart defects, such as aortic valve obstruction

Symptoms:
Symptoms and signs depend on the stage of shock:

1. Early shock:
• Increased heart rate (sometimes decreased in neonates <1000 g)
• Weak peripheral perfusion; prolonged capillary refill (>3 seconds)
• Cold, cyanotic extremities
• Pale or mottled skin
2. Established shock:
• Increased heart rate
• Low blood pressure
• Oliguria or anuria
• Lethargy
• Muscle hypotonia
3. Advanced shock:
• Signs of vital organ failure (lungs, kidneys, brain, heart)
4. Irreversible shock:
• Final stage of shock, characterized by:
• Oxygen deficiency and respiratory distress (cyanosis, tachypnea, grunting, chest retractions)
• Acidosis
• Arrhythmias
• Coma

Treatment:

• Prevention is the best strategy. If shock occurs, early recognition and a prioritized, goal-directed plan are essential to avoid serious complications.
• Administer 10–20 ml/kg of volume expanders (e.g., saline, Ringer’s, plasma) as directed by the physician.
• Monitor central venous pressure if possible to assess fluid balance.
• Treat hypoxia and hypoglycemia.
• Administer dopamine, dobutamine, or adrenaline according to physician instructions.

Nursing Care:

Maintaining Airway and Oxygenation:

• Keep airway open and ensure proper ventilation and oxygenation.
• Suction secretions if present.
• Monitor respiratory status and oxygen saturation using a monitor.
• Administer oxygen as needed according to blood gas results and physician orders.

Maintaining Circulation:

• Monitor vital signs, especially pulse, blood pressure, and temperature.
• Assess peripheral perfusion via capillary refill.
• Monitor consciousness and activity.
• Correct acidosis and ensure organ perfusion with medications such as dopamine, dobutamine, or sometimes adrenaline per physician instructions.

Controlling Bleeding and Replacing Fluids:

• Take measures to stop bleeding.
• Administer IV fluids via peripheral cannula or umbilical catheter.
• Transfuse blood products as directed.

Treatment of Septicemia:

• Administer antibiotics according to the identified pathogen and physician instructions.
