]]> Shock Index, Pediatric Age-Adjusted (SIPA) predicts mortality in children with blunt trauma

SIPA can be used in patients 4-16 years old who have sustained blunt trauma.

Loading...

4-16 years old only

* Required

SIPA should be calculated on presentation to the emergency department. Uptrending SIPA between the field and ED may predict poor outcomes but was not examined by the original authors.

  • SIPA can be used in patients 4-16 years old who have sustained blunt trauma
  • Do not use in young infants, toddlers, or patients with penetrating trauma.

Patients that present with an elevated SIPA are at higher risk of morbidity and mortality following blunt trauma. Early recognition and treatment in these cases, including a possible decision to transfer to a higher level of care, will improve outcomes in these children.

This predictive scale identifies severely injured children better than mildly injured children than the Shock Index (SI).

Indicators required for evaluation:

  • Age 4-16 years old only
  • Maximum heart rate Norm: 60-100
  • Minimum systolic blood pressure Norm: 100-120

Elevated SIPA is associated with the following outcomes (Acker 2015; Nordin 2017):

  • Higher injury severity.
  • Need for blood transfusion in the first 24 hours.
  • Longer ICU and hospital length of stay.
  • Higher number of ventilator days.
  • Discharge to a rehabilitation facility.
  • Increased risk of mortality.

SIPA = maximum heart rate/minimum systolic blood pressure, where normal values are as follows:

Interpretation

Age  Heart rate (normal ranges)Systolic blood pressure (normal values)Maximum normal SIPARisk of blunt injury if SIPA is elevated
4–6 years65–11090–1101.2222.0%
7–12 years60–100100–1201.0025.1%
13-16 years55–90100–1350.9032.0%

NB!

  1. The use of the SIPA shock index in the prehospital setting was not studied in the original study, so the use of this prognostic system in the prehospital setting is not recommended.  
  2. The use of SIPA to predict morbidity and mortality following admission has not yet been validated. However, a prognostic study in the Journal of Pediatric Surgery (Vandewalle 2018) found that patients who developed an elevated SIPA within the first 24 hours of admission were at increased risk of complications compared to those whose SIPA remained normal throughout the first 48 hours of admission. In addition, time to normalize SIPA directly correlated with length of hospital and ICU stay.
  3. Per the authors, the age-specific cutoffs originally chosen will require further validation.

The SIPA was originally developed by researchers at the Children’s Hospital of Colorado to help identify severely injured children following blunt trauma. Realizing that pediatric vital signs vary with age and that the standard SI may not be as useful in children, the researchers sought and defined maximum normal heart rate and minimum normal systolic blood pressure using reference ranges. Using these numbers, they determined the maximum normal SI for each age group.  The researchers then retrospectively looked at 543 children who presented to Children’s Hospital Colorado and Denver Health Medical Center between 1/2007 and 6/2013 following blunt trauma with Injury Severity Score >15.

Elevated SI was present in 49% of children, while elevated SIPA was present in only 27.6% of children (all of whom had the same adverse outcomes identified by using the SI). Hypotension is often a late finding in children with hypovolemic shock.

SIPA demonstrated improved discrimination of severe injury relative to SI in the following categories:

  • Injury Severity Score >30: 37% vs 26%.
  • Blood transfusion within first 24 hours: 27% vs 20%.
  • Grade III liver/spleen laceration requiring blood transfusion: 41% vs 26%.
  • In-hospital mortality: 11% vs 7%.

The researchers concluded that SIPA misses fewer children with severe injury while also minimizing over triage.
