Questions of IV administration What Define diagnosis/ clinical scenario and goal When Define time and rate Where Define patient setting (pre-hospital, ER, OR, Ward, ICU) How Define route and monitoring
Time dependence considerations Resuscitation Administration of fluid for immediate management of lifethreatening conditions associated with impaired tissue perfusion Titration Adjustment of fluid type, rate and amount based upon context to achieve optimization of tissue perfusion De-escalation Minimization of fluid administration; mobilization of extra fluid to optimize fluid balance
Fluid balance Daily fluid balance daily sum of all intakes and outputs Cumulative fluid balance sum total of fluid accumulation over a set period of time Fluid overload cumulative fluid balance expressed as a proportion of baseline body weight. A value of 10% is associated with adverse outcomes; 5% is after SICU admission

Rescue phase Characters Principles Goals Time Type Fluid therapy Scenario Details Lifesaving Correct shock Minutes Severe shock Rapid boluses Septic shock, Major trauma
Fluid bolus A rapid infusion to correct hypotensive shock. It typically includes the infusion of at least 500 ml over a maximum of 15 min Monitor: (More simple) Minimum : BP, HR, Lactate, ABG, Cap.refill, Urine, Mental status Optimum : Echo/Doppler, CVP
Determination of fluid choice Phase of fluid resuscitation Fluid compartment Patient diseases Complication
Fluid compartments IV IS Cell 5% BW 15%BW 40% BW ECF=20%BW ICF=40%BW
Water without Na fluid crystalloid IV 5% BW All compartment resuscitation IV:IS:IC=1:3:8 IS Cell 15%BW 40% BW ECF=20%BW ICF=40%BW Cellular and IS edema
Isotonic Na containing fluid crystalloid IV 5% BW ECF resuscitation IV:IS = 1:3 IS Cell 15%BW 40% BW ECF=20%BW IS edema ICF=40%BW
Isotonic Na containing isotonic colloid fluid IV 5% BW IV resuscitation IS Cell 15%BW 40% BW ECF=20%BW ICF=40%BW
Cellular dehydration Isotonic Na containing hypertonic colloid IV IV resuscitation IS Cell 20-25% Albumin 5% BW 15%BW 40% BW ECF=20%BW ICF=40%BW
Fact of cellular shock during rescue phase Interstitial water depletion Intravascular volume compensation So Crystalloid fluid is first fluid choice Caution Failing organs Interstitial edema esp. pulmonary edema Low energy supply condition or cellular shock Hyperchlorimic normal gap metabolic acidosis
Comparison of albumin resuscitation to other fluid regimen in sepsis Guidelines currently suggest (grade2c) that albumin use should be considered as a resuscitation fluid in patients with severe sepsis, particularly if those patients are not responding to crystalloid infusion Delaney AP et al. Crit Care Med 2011;39:386-91.
Traumatic brain injury (SAFE group) 28 days mortality 24 months mortality The hypotonic and hypooncotic nature of the albumin solution used may also have played a role N Engl J Med 2007;357:874-84.
Summary of rescue phase Crystalloid first Sepsis : avoid HES, prefer albumin if crystalloid is not work Traumatic brain : avoid albumin Use basic monitoring

Stabilization Characters Principles Goals Time Type Fluid therapy Scenario Details Organ support Aim for zero or negative fluid balance Days Stable Minimal maintenance infusion only if oral intake inadequate NPO postoperative patient Drip and suck management of pancreatitis
Fluid infusion Continuous delivery of i.v. fluids to Maintain homeostasis, Replace losses, or Prevent organ injury (e.g. prehydration before operation or for contrast nephropathy) Monitoring Minimum: Same as optimization (attention on balance) Optimum: +/- Echo/Doppler, CVP, ScvO 2, CO
Volume status of resuscitation (www.adqi.org)
De-escalation Characters Principles Goals Time Type Fluid therapy Scenario Details Organ recovery Mobilize fluid accumulated Days to weeks Recovering Oral intake if possible Avoid unnecessary IV fluids Patient on full EN in recovery phase of critical illness Recovering ATN
Maintenance Fluid administration for the provision of fluids for patients who cannot meet their needs by oral route. This should be titrated to patient need and context This should include replacement of ongoing losses. In a patient without ongoing losses, this should probably be no more than 1 2 ml/kg/ h Monitoring Minimum: Same as optimization (attention on negative) Optimum: +/- Echo/Doppler, CVP, ScvO 2, CO
