Final answer:
The recommendation for a fluid bolus of isotonic crystalloids in cardiogenic shock is cautious and requires careful monitoring. NaCl solution can be used for dehydration, but fluid therapy in cardiogenic shock should be titrated to avoid worsening the condition.
Step-by-step explanation:
When addressing cardiogenic shock, and considering the administration of a fluid bolus of isotonic crystalloids, the recommendation is cautious. For patients without signs of hypovolemia, care must be taken to avoid fluid overload, which can worsen pulmonary edema and myocardial function.
Despite ordinary NaCl solution being viable for parenteral correction of dehydration, administering a bolus of isotonic crystalloids in cardiogenic shock requires individual assessment with close monitoring of cardiac function and volume status.
For fluid loss high in Na and HCO3, a specific mixture of 2/3 isotonic saline and 1/3 Na lactate may be used intravenously to address the imbalance. Nevertheless, in cardiogenic shock, PALS (Pediatric Advanced Life Support) guidelines emphasize the importance of titrating fluid therapy to the patient's response and avoiding excessive fluid administration, especially in the context of compromised cardiac function
