Description
Pediatric septic shock, a life-threatening condition primarily caused by systemic bacterial infection, demands swift diagnosis and multidimensional management. Early recognition hinges on a high index of suspicion, integrating clinical signs like altered mental status, hypotension, tachycardia, and poor perfusion. Timely initiation of broad-spectrum antibiotics targeting likely pathogens is paramount, alongside aggressive fluid resuscitation to restore adequate perfusion. Hemodynamic support, including vasoactive agents, may be necessary to stabilize blood pressure. Close monitoring for signs of organ dysfunction guides ongoing interventions, encompassing tailored antimicrobial therapy and supportive care to mitigate complications. Collaborative efforts among multidisciplinary teams are indispensable for optimizing outcomes in pediatric septic shock.
Résumé
- Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to an infection. Septic shock is a more severe form of sepsis, carrying a higher risk of mortality. The older SIRS criteria have been replaced by the SOFA score for assessing organ function. The newer definition of sepsis faces challenges, especially in developing countries, like eliminating sepsis without organ dysfunction and limited access to lactate level checks.
- Shock occurs when a child's perfusion is inadequate to maintain blood pressure and oxygen supply to tissues. Compensated shock is characterized by normal blood pressure with signs like tachycardia and poor peripheral perfusion. Hypotensive shock includes low blood pressure, altered sensorium, and weak central pulses, in addition to signs of compensated shock.
- The management of shock involves fluid resuscitation, with balanced salt solutions being preferred over normal saline to avoid hyperchloremic metabolic acidosis. Intravenous access is crucial; if difficult to obtain, intraosseous access should be considered. The amount of fluid administered depends on the patient's condition and available resources, with a cautious approach in resource-limited settings.
- After fluid resuscitation, broad-spectrum antibiotics should be initiated based on institutional guidelines and resistance patterns. Continuous reassessment is necessary after each intervention. Other interventions include steroids, maintaining glucose levels, and early consideration of ECMO for refractory shock. Assessing fluid overload is essential to prevent complications.
- Vasopressors like epinephrine or adrenaline are preferred over dopamine as first-line agents in pediatric septic shock. Dobutamine with noradrenaline are used for cardiogenic shock. Hydrocortisone should be considered if the child is not responding to vasopressors. Early initiation of appropriate antibiotics and source control are crucial. Steroids and supportive management like early intubation and restrictive blood transfusion are essential.
- Documentation is paramount, including a structured format that captures subjective assessments, objective data, opinions, and the agreed plan. Counseling the family, documenting the sequence of events, interventions, and possible outcomes are also vital aspects of managing pediatric septic shock.
