Fluid Therapy

Resuscitation

Right fluid, right volume, right time — reassess dynamically.

Crystalloid choice

  • Balanced (PlasmaLyte / Ringer's) preferred over 0.9% NaCl for resuscitation
  • Saline OK for short courses / specific indications

Resuscitation

  • Initial 30 mL/kg in septic shock (over first 3h)
  • Reassess after each 250-500 mL bolus

Maintenance

  • Adult ~25-30 mL/kg/day water
  • 1 mmol/kg/day Na and K

Avoid

  • Excess saline (hyperchloraemic acidosis)
  • Hydroxyethyl starch
  • Over-resuscitation (pulmonary oedema, AKI)

Pearls

  • Passive leg raise / VTi for fluid responsiveness
  • Stop fluid bolus when CVP / lung US shows congestion

Educational support only — follow institutional ICU protocols.
