Recognizing and managing pediatric shock requires understanding normal blood volume and administering fluid resuscitation. Early recognition of hypovolemic shock and prompt, adequate fluid replacement, including blood transfusion if necessary, are critical for successful outcomes in children.
Area of Science:
- Pediatric Emergency Medicine
- Pediatric Critical Care
- Pediatric Resuscitation
Background:
- Effective management of pediatric shock is often hindered by delayed recognition and inadequate fluid replacement.
- Familiarity with normal pediatric blood volume is crucial for appropriate resuscitation strategies.
Purpose of the Study:
- To outline common errors in pediatric shock management.
- To provide practical guidelines for fluid resuscitation in pediatric hypovolemic shock.
Main Methods:
- Calculating normal blood volume as 40 ml/lb (88 ml/kg) for children.
- Administering initial intravenous boluses of Ringer's lactate solution (10 ml/lb or 22 ml/kg).
- Assessing response to fluid boluses and considering blood transfusion or paracentesis for persistent hypotension or suspected intra-abdominal bleeding.
Main Results:
- Hypovolemic shock involves a blood volume reduction of at least one fourth.
- A single fluid bolus may normalize blood pressure; otherwise, a second bolus is indicated.
- Children requiring a second fluid bolus often necessitate blood transfusion and evaluation for occult bleeding.
Conclusions:
- Accurate assessment of pediatric blood volume is essential for appropriate fluid resuscitation.
- A stepwise approach to fluid administration and consideration of blood transfusion are key in managing pediatric shock.
- Investigating occult bleeding is important in children with persistent hypotension despite fluid resuscitation.
Abstract:
Common errors in managing shock in children are failure to recognize shock, failure to recognize continuing blood loss, and inadequate replacement due to lack of familiarity with the normal blood volume of children. For practical purposes, the normal blood volume of every child is considered to be 40 ml/lb (88 ml/kg). In hypovolemic shock the blood volume is reduced by at least one fourth. For initial management, an intravenous line is established, blood is drawn for cross matching, and 10 ml/lb (22 ml/kg) of Ringer's lactate solution is administered as rapidly as possible. If this bolus, which represents one fourth of the normal blood volume, brings the blood pressure to normal, only maintenance fluid is then administered. If the child remains hypotensive, a second bolus of 10 ml/lb (22 ml/kg) is administered rapidly. Children who require a second bolus of Ringer's lactate solution nearly always need blood transfusion also. Many have occult bleeding, usually in the abdomen. If intra-abdominal bleeding is thought to be possible but not definitely present, paracentesis using an angiocath is performed. If no blood returns, 10 ml/lb (22 ml/kg) of saline is instilled and the return considered significant if more than slightly pink.
