Plan of management
•
•
•
•
•
•
•
•
Hourly vital signs monitoring until stable
Notify as Dengue Haemorrhagic Fever
Run 2 pint NS fast
Maintenance IVD 8 pints Normal Saline over 24 H
IV Maxolon 10 mg tds
T. Ranitidine 150 mg bd
4 hourly FBC
TDS MO review
16
Does the patient fulfill the criteria
for DHF ?
17
WHO classification - DHF
Features of dengue fever
And
2. Hemorrhagic manifestations evidenced through one or more of the
following:
a. Positive tourniquet test
b. Petechiae / ecchymosis / purpura
c. Mucosal bleeding: Epistaxis, gum bleeding
d. Bleeding from injection or other site
e. Hematemesis, melena, hematuria, PV bleeding
3. Thrombocytopenia with platelets 100,000 / m3 or less
And
4. Any evidence of plasma leakage due to increased capillary permeability
manifested by one or more of the following:
a. A >20% rise in hematocrit for age or sex
b. A > 20% drop in hematocrit following treatment with fluids as
compared to base line
c. Pleural effusion / ascites / hypoproteinemia
1.
18
Evidence of plasma leakage
Haemoconcentration (20%
above baseline)
A drop in haematocrit following
fluid replacement
Adult male
 Hct >46%
3rd space
fluid
accumulation
Adult female
Hct >40%
In addition, unexplained tachycardia
19
Pleural
effusion,
Ascites

Comment on the fluid regime given ?


There is no evidence of hemodynamic instability
Bolus not necessary


20
Unnecessary boluses will contribute to the extravasation of
fluids to the extravascular space such as pleural and abdominal
cavity resulting in massive pleural effusion and ascites.
Calculation for normal maintenance fluid is wrong
21
Comment on these orders
‘T. Ranitidine 150 mg bd’
‘4 hourly FBC’
‘TDS MO review’
•
•

22
H2-antagonist is not indicated
At least in critical phase of dengue illness – every FBC
taken must be reviewed and action taken based on the
result, hemodynamic status and other clinical parameters.
‘Dengue infection is a dynamic disease. Its clinical
course changes as the disease progresses’

For patients in the critical phase, a good doctor’s order
must include





Fluid regime that is based on ml/hr or ‘1 pint every….hour’
The time for next clinical review
The time for next FBC
The fluid regime must be applicable only until the next clinical
review
‘Frequent adjustment of maintenance fluid regime
is often needed during the critical phase’
23
Next review - 13 hours defervescence– Day 5
fever onset ( 21/5/08 , 9am )





Vomit x 1 , Epigastric pain
No diarrhoea or hematuria
BP : 107/70 mmHg PR : 81 sPO2 100% ↓Room Air
Lungs : clear
Order ( by doctors )





24
Trace FBC taken at 7.00AM
T Omeprazole 40mg OD ( off T Ranitidine )
Watch out for bleeding tendency
Cont IVD 8 pint Normal Saline over 24 hours
Transfer to Dengue Ward after review result
Monitoring in dengue

Comment on the review frequency

This patient is in critical phase and has alarm signals



25
A review by the on-call doctor is necessary in order to pick up early
evidence of leakage
We need to find a way to risk stratify our dengue patients and
the management of high risk cases must be a by a dengue team.
It is not enough if we just try to place all our dengue patients
in one ward (which is often overflowing)

What are the signs of deterioration that were not
appreciated by the doctor?

In dengue infection it is more important to look out for plasma
leakage than ‘watch out for bleeding tendency’


26
New onset of epigastric pain
Pulse rate increasing
 All this implies the need for closer monitoring
 More frequent HCT estimation
Pathophysiology of DHF
Clinical manifestations of vasoconstriction (secondary
to plasma leakage) in various systems are;

Skin


Cardiovascular system


lethargy, restlessness, apprehension, reduced level of consciousness
Respiratory system

27
vomiting and abdominal pain
Central nervous system


reducing urine output
Gastrointestinal system


raised diastolic blood pressure and a narrowing pulse pressure
Renal system


coolness, pallor and delayed capillary refill time
tachypnoea (respiratory rate >20/min)
27
18 hours defervescence(21/5/08, 2pm )
•

•
Not transferred to Dengue Ward yet
Blood Investigations taken at 7.00AM reviewed :
– ALT : 407 / AST : 1230
– CK : 359 / LDH : 1912
– WCC : 2.10 Hb : 13.6 Hct : 39.3 Plt : 19.4
– Cr: 70 / Urea :3 / K :2.85
– PT:15 / PTT:76.6 / INR : 1.3
CXR : Clear lung fields
28

Comment on the HCT value at 7.00AM
 HCT is 39.3 despite fluid replacement
 Early and excessive fluid replacement is masking the raise
in HCT

Input /Output charting
20/5/08 : 3300 / 1000 cc


HCT values must be interpreted in the context of
the patient’s clinical progress and the amount of
fluid replacement.
Other evidence for plasma leakage must be looked
for during clinical examination

29
3rd space accumulation of fluids – pleural effusion and ascites
25 hours defervescence(21/5/08, 9pm)
•
Reviewed by doctor on call :
• Comfortable ?????
• sPO2 99% ( room air )
• BP : 116/52mmHg
• PR : 104 /min
• T : 37.7oC
• ABG : pH 7.43 pCO2 44 PO2 153 HCO3 28 BE 4
• Order – Continue ward management
30

Comment on the use of ABG at this stage
 Acidosis is a late sign of disease severity in Dengue
 There are other indicators that the patient is
deteriorating



31
Pulse rate 104/min
In the previous review and subsequent review, the doctors have
mentioned about ‘epigastric pain’, which is a warning sign
Respiratory rate is a useful marker of 3rd space fluid
loss and hence need to be assessed
32

What will be correct

patient condition?

Comment on the usage of frusemide at this stage




47
Periorbital swelling, pedal oedema and possibly pleural effusion
is evidence of extravasation of fluid to extravascular space
Initial overzealous fluid replacement can be the cause of this
However patient is still in the leakage phase and hence has
intravascular depletion
Frusemide makes this worse

Investigation results


ABG – worsening compensated metabolic acidosis
pH 7.36 HCO314 BE -9 pCO2 27
Management :
 IV frusemide 40mg stat
 Transfer to HDU
 IVD 1 pint over 24 hours
 IV NaHCO3 50cc slow bolus
53

Comment on the sodium bicarbonate infusion
54






No indication in this scenario as cause of acidosis here is
due to hypovolemic shock both from plasma leak and
occult hemmorhage
Does more harm than good
1) paradoxical intracellular acidosis- increases CO2
2)worsens fluid overloads
3)hyperosmolar - hypernatremia
The indication to give in very severe metabolic acidosis
where the pH is <7.1 is also just as a temporary measure
while awaiting renal replacement therapy which is
definative treatment
55

What is happening in this patient now?


Occult Bleeding causing a drastic drop in Hb and Hematocrit

Marked clinical deterioration from organ failures especially liver
failure (hepatitis and severe coagulopathy , no DIC screen but
possibly in DIC), and with lung injury and renal impairment
ORGAN FAILURE IS TOO LATE TO REVERSE AND SEE THE TIME
FRAME AND RAPIDITY THAN THE PATIENT DETERIORATED
Management : PURELY SUPPORTIVE
Transfusion of blood and blood products accordingly; also realising
that all this is going to impair your oxygenation and patient will soon
require intubation, inotropes and CVVHD
