Insights
In pediatric septic shock, intravenous calcium chloride infusion improved blood pressure in a patient refractory to standard treatments. This intervention allowed for reduced doses of other vasopressors.
Area of Science:
- Pediatric Critical Care Medicine
- Pharmacology
- Intensive Care
Background:
- Pediatric septic shock presents significant morbidity and mortality, with standard management including fluids, antibiotics, and vasopressors like epinephrine and norepinephrine.
- Additional therapies for refractory pediatric septic shock are not well-defined, with many agents impacting cellular calcium pathways.
- Children's unique physiology may increase susceptibility to calcium's vasoactive effects.
Purpose of the Study:
- To investigate the potential of intravenous calcium infusion as an adjunctive therapy for pediatric septic shock.
- To explore calcium's role in improving vasoactivity in pediatric septic shock, potentially bypassing signaling pathways.
- To present a case study of calcium chloride infusion in a patient with refractory septic shock.
Main Methods:
- A case report detailing the management of a pediatric patient with septic shock.
- The patient received standard resuscitation, antibiotics, epinephrine, and norepinephrine.
- Continuous intravenous calcium chloride infusion was initiated due to persistent hypotension.
Main Results:
- The patient remained hypotensive despite fluid resuscitation, antibiotics, epinephrine, and norepinephrine.
- Initiation of a continuous calcium chloride infusion led to improved blood pressure.
- Doses of norepinephrine and epinephrine were subsequently reduced following calcium chloride administration.
Conclusions:
- Intravenous calcium chloride infusion may be a viable adjunctive therapy for pediatric septic shock refractory to standard treatments.
- Calcium chloride may enhance vasoactivity in the smooth muscle, offering a potential alternative or supplement to other vasopressors.
- Further research is warranted to establish the safety and efficacy of calcium infusions in pediatric septic shock management.
Abstract:
Pediatric septic shock is a life-threatening condition with significant rates of morbidity and mortality. Standard management includes fluid resuscitation, timely antimicrobial administration, and epinephrine or norepinephrine if unresolved with initial management. Additional therapies are not well defined and include vasopressin, hydrocortisone, phenylephrine, levosimendan, dopamine, and others. Many of these agents modify cellular effects of calcium in the smooth muscle. The use of a calcium infusion may improve vasoactivity in the smooth muscle without the use of signaling pathways. Children are more susceptible to the effects of calcium, which may predispose them to enhanced vasoconstriction with the administration of intravenous calcium. We present a case in which a patient on chronic calcium channel blocker therapy presented with septic shock. She continued to remain hypotensive after fluid resuscitation, antibiotics, epinephrine, and norepinephrine. Her blood pressure improved with the initiation of a continuous calcium chloride infusion. Norepinephrine and epinephrine doses were decreased after the initiation of the calcium infusion.
