• To differentiate DHF from DF
• Assessing onset of Critical Phase of DHF• Smooth manipulation of fluids averting
prolonged shock and fluid overload
• Early detection of complications
• Recognition of unusual presentations

• Pulse rate• Pulse pressure• CRFT• Respiratory rate• FBC - HCT• Intensity of monitoring depends on
• Phase of the illness• Severity• Aggressiveness of fluid therapy
• Accurate fluid balance charts

• Dengue or not?– Clinical– FBC
• Leucopaenia + thrombocytopaenia
• DF or DHF ?– Plasma leakage + or –
• If DHF – what is the phase ?

• Critical phase– Time of entry– Predicted time of end
• Aggressive monitoring• Calculate the fluid quota• Dynamic approach to fluid therapy• Final diagnosis – precise (DF or DHF &
grade)

• Dropping Platelets • HCT rise of more than 20% of base lineConforms DHF as it signify leak.Even If HCt rise less than 20% but pleural
effusion/ascites present conforms diagnosis of DHF/DSS( it is mostly due to early volume replacement or bleeding).

• Febrile phase • Critical phase • Convalescent phase
• Day of the illness ?• Evidence of plasma leakage ?
• Convalescent rash ?

• Detection of shock• Pulse pressure < 20 mm Hg• CRFT > 2 secs• HCT increase of 20% or more from baseline
• Efficacy of IV fluid therapy• Pulse pressure, capillary refill time, hypotension• To keep urine output at least 0.5 – 1.0 ml/kg/hr
• Early detection of Fluid overload• Respiratory rate > 20/mt • Lung bases• SaO2 < 92% • CXR

•Misjudging of critical phase which could begin as early as day 3 (if fever drop on day 3). • Delay in doing the WBC, platelets and Hct determinations. which help predict the critical stage/shock Lead to misdiagnosis and/or delay until shock
occur.

• Be vigilant to recognize DSS as most of the patients remain in good conscious and have narrow pulse pressure with increased diastolic pressure(e.g.BP=110/90, 100/80mm Hg) without hypotension.
• Avoid misdiagnosis of DHF in Infants(<1 year) with fits as sepsis/infection followed by LP leading to bleeding/ hematoma(platelets )

• Your initial timing of critical phase may prove to be sometimes wrong
Be prepared to change what you decided earlier or shift the timing based on more information you receive while Mx.

• Try to Master the ways of giving ‘ THE SMOTHEST AND THE MOST
UNEVENTFUL RECOVERY’ for the patient.
• Avoid both shock and fluid overload.• Keep ‘CHECKING ON A TIME SCALE’…
R u heading for fluid overload? If so, switch to a colloid.

• At ‘END OF LEAKING PHASE’ even if PCV is high but patient is well, pulse, BP is OK
• Don’t try to correct PCV as re absorption will start soon and PCV will come down so..
WAIT.

•About 60% of DSS can be successfully resuscitated by using crystalloid solution only, 20% need colloidal and 15% need blood transfusion (+blood components). •With rapid recognition of shock and proper treatment rapid and dramatic recovery is the rule
