Fluid Resuscitation in Sepsis with Large Pleural Effusion

Initial Resuscitation Approach

The Surviving Sepsis Campaign guidelines recommend administering at least 30 mL/kg of crystalloid within the first 3 hours of sepsis recognition, with moderate quality evidence 1, 2
The American College of Critical Care Medicine suggests using balanced crystalloids, such as lactated Ringer's or Plasma-Lyte, rather than normal saline to reduce the risk of hyperchloremic metabolic acidosis 2
Delayed resuscitation increases mortality, and immediate fluid resuscitation is required despite concerns about the pleural effusion, according to the Surviving Sepsis Campaign guidelines 1, 2

The European Society of Intensive Care Medicine recommends stopping fluid administration immediately if crepitations develop or respiratory status worsens, as aggressive fluid resuscitation can lead to respiratory impairment 3
After initial fluid boluses, subsequent fluid administration should be performed extremely cautiously if mechanical ventilation is not available, as suggested by the European Society of Intensive Care Medicine 3

The Surviving Sepsis Campaign guidelines suggest administering smaller boluses of 250-500 mL and reassessing after each bolus, rather than giving the full 30 mL/kg rapidly 4
Fluid administration should continue only as long as hemodynamic parameters continue to improve without respiratory deterioration, according to the Surviving Sepsis Campaign guidelines 1, 2
The European Society of Intensive Care Medicine recommends monitoring for positive response, including a ≥10% increase in systolic/mean arterial pressure, ≥10% reduction in heart rate, improvement in mental state, peripheral perfusion, and urine output 3

The European Society of Intensive Care Medicine recommends stopping fluid administration immediately if no improvement in tissue perfusion occurs despite volume loading, or if development of crepitations indicating fluid overload or impaired cardiac function occurs 3, 1
Fluid administration should also be stopped if worsening respiratory distress occurs, including dyspnea, wheezing, inability to speak sentences, or SpO2 ≤90%, as suggested by the European Society of Intensive Care Medicine 3

The Surviving Sepsis Campaign guidelines suggest considering initiating norepinephrine earlier if hypotension persists after a smaller initial fluid volume, targeting MAP ≥65 mmHg 2, 4
This approach maintains perfusion while limiting excessive fluid administration in a patient with compromised respiratory reserve, according to the Surviving Sepsis Campaign guidelines 4

The European Society of Intensive Care Medicine recommends never leaving the septic patient alone and ensuring continuous observation, with clinical examinations performed several times per day 3
The Surviving Sepsis Campaign guidelines suggest monitoring heart rate, blood pressure, oxygen saturation, respiratory rate, urine output, skin perfusion, and mental status 1
Dynamic measures of fluid responsiveness, such as pulse pressure variation and stroke volume variation, should be used rather than relying solely on static measures like CVP, as recommended by the Surviving Sepsis Campaign guidelines 1, 2
