    Group AMay be sent home Group BReferred for in-hospital care Group CRequire emergency treatmentGroup criteria

    Patients who do not have warningsigns

    ANDwho are able:

    o To tolerate adequate volumes

    of oral fluids

    o To pass urine 3-4 times per day

    Group criteria

    Patients with any of t he following features:

    o Existing warning signs OR o Co-existing conditions such aspregnancy, infancy, o ld age, diabetes

    mellitus, renal failureo Social circumstances such as l iving

    alone, living far from hospital

    Group criteria

    Patients with any of the following features.o Severe plasma leakage with shock and/or fluid

    accumulation with respiratory distress

    o Severe bleeding

    o Severe organ impairment

    Laboratory tests

    o Full blood Count (FBC)o Haematocrit (Hct)

    Laboratory tests

    o Full blood Count (FBC)o Haematocrit (Hct)

    Laboratory tests

    o Full blood Count (FBC)o Haematocrit (Hct)

    Treatment

    Advice for:o Adequate bed rest

    o Adequate fluid intake

    o Paracetamol, 4 gram max. per

    day

    Patients with stable Hct can be sent

    home

    Treatment

    o Obtain reference Hct before fluid therapyo Give isotonic solutions such as 0,95 saline, Ringer

    lactate, start with 5-7 ml/kg/hr for 1-2 hours, then

    reduce to 2-3 ml/kg/hr or less according to clinical

    response

    Reassess clinical status and repeat Hcto

    If Hct remains the same or rises only minimally ->

    continue with 2-3 ml/kg/hr for another 2 -4 hours

    o If worsening of vital signs and rapidly rising Hct - >

    increase rate to 5-10 ml/kg/hr for 1-2 hoursReassess clinical status, repeat Hct and review fluid

    infusion rates accordingly

    o Reduce i ntravenous fluids gradually when the rate

    of plasma leakage decreases towards the end of thecritical phase.

    This is indicated by:

    o Adequate urine output and/or fluid intake

    o Hct deceases below the baseline value in a stablepatient

    Treatment

    o Encouragement for oral fluidso If not tolerated, start intravenous

    fluid therapy 0,9% saline or

    Ringer Lactate at maintenance rate

    Treatment of shock:

    o Start intravenous fluid resuscitation with isotoniccrystalloid solutions at 5-10 ml/kg/hr

    o Reassess patients s condition,

    If patient improves:

    o Intravenous fluids should be reduced gradually to 3-

    5 ml/kg/hr, then to 2 -3 ml/kg/hr and then dependingon haemodynamic status

    o Can be maintained for up to 24 - 48 hours

    If patient still unstable:

    o Check Hct after first boluso If Hct increases/ still high (>50%), repeat a second

    bolus of crystalloid solution at 10-20 ml/kg/hr.

    o If improvement after second bolus, reduce rate to 7-

    10 ml/kg/hr, continue to reduce as aboveo If Hct decreases, this indicates bleeding and n eed to

    cross-match and transfuse blood as soon as possible

    Treatment of hypotensive shock

    Monitoring

    o Daily review for warning signs

    (until out of critical period)

    o Advice for immediate return tohospital if development of any

    warning signs

    o Written advice of management

    (e.g. home card for dengue)

    Monitoring

    o Vital signs and peripheral perfusion (1-4 hourly

    until patient is out of critical phase

    o Urine output (4-6 hourly)o Hct (before and after fluid replacement, then 6-12

    hourly)

    o Blood glucose ( before f luid replacement and repeat

    as indicatedo Other organ functions (renale profile, liver profile,

    coagulation profile, before fluid replacement and as

    indicated)

    Monitoring

    o Temperature pattern

    o Volume of fluid intake and losses

    o Urine output volume andfrequency

    o Warning signs

    o Hct, white blood cell and platelet

    counts

    o Initiate IV fluid resuscitation with crystalloid or

    colloid solution at 20 ml/kg as a bolus for 15 min

    If patient improves

    o Give a crystalloid / c olloid solution of 10 ml/kg/hr,them reduce gradually

    If patient still unstable

    o Check Hct after the first bolus

    o

    If Hct increases/ still h igh (>50%), change IV fluidsto colloid solutions at 10 ml/kg/hr, then reduce to 7-

    10 ml/kg/h, then change back to crystalloid solution

    and reduce rate as above

    o If HCT decreases, this indicates bleeding, see a bove

    Treatment of haemorrhagic complications:

    o Give 5-10 ml/kg of fresh packed red cells or 10-20

    ml/kg of fresh whole blood

    Presumptive Diagnosis:

    Neighbourhood dengue/travel to endemic area plus

    Fever and two of the following: Anorexia and nausea Rash Aches and pains +/- warning signs Leucopenia
