Dengue Hemorrhagic Fever or Dengue Leaking Fever
Essential Feature In DHF is LeakingDF may have bleeding but not leaking
![Page 5: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/5.jpg)
The Cause of Shock in Dengue
• Plasma leakage• Bleeding – external and internal • Hypocalcaemia • Vascular involvement • Inadequate fluid intake• Myocarditis
![Page 6: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/6.jpg)
What is the cause of Plasma Leakage
Endothelial cell dysfunction rather than destruction
![Page 7: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/7.jpg)
Evidence of Plasma Leakage
• Rise in HCT – 20% = children 35 42 adults 40 48
• Circulatory failure• Fluid accumulation – Ascites, Pleural
effusions• Albumin < 3.5 gr/dl • Cholesterol < 100 mg%
![Page 8: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/8.jpg)

Plasma Leakage Shock Prolonged shock
• Prolonged shock – Organ hypo perfusion & Organ impairment– Metabolic acidosis + DIC – Severe Hemorrhage ( Drop HCT & rise of
WBC )
All these complications may develop without obvious plasma leakage or shock
![Page 10: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/10.jpg)
Rising HCT indicate plasma leakage
• 20-30% rise GIT ischemia including liver • 30-40 % rise Renal and brain ischemia
![Page 11: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/11.jpg)
Patients at risk of major bleeding
• Prolonged/refractory shock;• Hypotensive shock & renal or liver failure • Severe and persistent metabolic acidosis;• Receiving NSAID agents;• Pre-existing peptic ulcer disease;• On anticoagulant therapy;• Any form of trauma( IM injection)

Optimum volume of
fluid …
M + 5%
![Page 16: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/16.jpg)
Calculation of M +5%
• Calculation of M– 1st 10 kg – 100 ml/kg/day ( 4 ml/kg/hr)– 2nd 10 kg – 50 ml/kg/day ( 2 ml/kg/hr)– Subsequent ..kg – 20 ml/kg/day ( 1ml/kg/hr)
• Calculation of 5%– 5% = 50ml/kg/day ( 2ml/kg/hr)
Maximum Fluid for adult ( 50kg) = 4600
M+ 5% for boy 60kg (IBW 50kg ) = ?

Rational Use of Fluid = Management of Dengue
Avoid Fluid Overload
![Page 19: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/19.jpg)
Spectrum of Dengue
• DHF Grade 4 ( SD with hypotnsive shock ) – No pulse – 20ml/kg rapid bolus– Drop SBP (Pulse + ) – 10 ml/kg rapid bolus, Rpt sos
• DHF Grade 3 ( SD with compensated shock)– 10 ml/kg/hr
• No circulatory failure ( D warning signs)– DF +/- Bleeding ( oral fluid ? M+5%)– DHF in Febrile phase (1.5 ml/kg/hr)
![Page 20: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/20.jpg)
DF & DHF in Febrile Phase
![Page 21: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/21.jpg)
DF & DHF in Febrile Phase
• Parcetamole 15mg/kg 6 hrly • Physical methods of controlling fever• Don’t use Aspirin and NSAID• Fluid to maintain nutrition and hydration
– Oral – between M and M+5% ( 5ml/kg/hr)

Too much fluid during febrile phase can contribute
to fluid over load
![Page 22: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/22.jpg)
Recognize the Time of Entry to the Critical Phase
( when blood vessels become leaky)
• Dropping platelet count below 100 000/dl• Rising HCT & Evidence of plasma leakage
![Page 23: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/23.jpg)
Fluid management during Critical Phase not in shock
( when blood vessels become leaky)
• Establish IV line & IV fluid to KVO • Limit total ( IV + Oral) fluid to 1.5 ml/kg/hr• Monitor UOP ( 0.5ml/kg/hr is OK) • Rising HCT - Increase fluid- 3-5-7-10 ml/kg/hr• Monitor for circulatory failure – Fluid boluses
HCT monitoring 4-6 hrly initially then hrly

Prolonged shock
![Page 28: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/28.jpg)
Prolonged Shock
• Detecting absent pulse is too late• Drop in SBP is too late• Drop in pulse pressure, CRFT, Cold
extremities .. can detect early shock• We can prevent shock !
Rise in HCT = loss of IV compartment 20% - compromise GIT blood supply40% - compromise renal and brain

Cause of Prolonged Shock in Dengue
• Failure to detect shock is rare in SL• Clinicians thought prolonged shock is due to bleeding
as a result of low platelets • Clinicians did not appreciate that shock precipitate
bleeding and other organ damage • Clinicians did not monitor/manage PCV ( instead they
managed platelet count ) personal opinion
WHY ?Lack of knowledge and training WHY ?Failures in teaching/training programs
![Page 31: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/31.jpg)

Patients not responding to usual fluid boluses
• Massive plasma leakage – rising PCV• Concealed hemorrhage – Drop of PCV• Hypocalceamia • Hypoglycaemia • Hyponatremia• Acidosis
![Page 40: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/40.jpg)
Fluid Management During Critical Phase DON’T OVER LOAD LEAKING VESSELES
• Manage PCV and shock; use monitoring chart• Fluid quota for leaking phase is M+5%
– Pre shock in 48 hours , Grade 3& 4 in 24 hours
• Use colloids to retain longer • UOP – 0.5 ml/kg /hr is OK (Void volume chart)• Cut down fluid at recovery phase
– Eg - 10ml/kg/hr 1.5 ml/kg/hr
• Give blood when indicated

What is M+5% in management of DHF (MCQ)
• Fluid volume to be given during critical period after excluding boluses
• Fluid volume to be given during critical period after including boluses
• Upper limit of fluid volume for critical period• Upper limit that should never be exceeded
M + 5% is only a guide to understand the risk for fluid over load

Fluid Management in Recovery Phase
![Page 45: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/45.jpg)
Fluid Management in Recovery Phase
Dengue patients have accumulated fluid within his/her body
• Cut down fluid • Give oral fluid if tolerating• Dropping HCT is not bleeding• Rising HCT in stable child manage with oral
fluidDHF grade 3 recovery phase; nurse inform that child has massive
meleana HCT dropped to 35 !Don’t panic if the child is stable, hematocrit 35 is because he is recovering
child is passing what he bled yesterday
![Page 46: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/46.jpg)
6 yr old boy DHF grade 4 recovered after 3 fluid boluses. His HCT dropped from 48 to 39.
However he again developed circulatory failure with reduced pulse pressure.
![Page 47: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/47.jpg)
Management of severe bleeding
• Probably he has internal bleeding• Manage with
–10 ml/kg whole blood–5 ml/kg Packed RBC
![Page 48: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/48.jpg)
Indications for Blood Transfusions
• Overt bleeding ( more than 10% or 6-8ml/kg)• Significant drop of HCT < 40 ( < 45 for males)
after fluid resuscitation • Hypotensive shock + low/normal HCT • Persistent or worsening metabolic acidosis• Refractory shock after fluid 40-60 ml/kg
only 10-15% patients need blood
Circulatory failure with high HCT should be managed with colloids ( + Lasix if fluid overloaded) before blood

Fluid Over Load
![Page 52: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/52.jpg)
Causes of Fluid Over Load • Too much fluids in febrile phase• Excessive and/or too rapid IV fluids• Use of hypotonic crystalloid solutions• Inappropriate IV fluids for “severe bleeding”• Inappropriate - FFP, platelet & cryo• Continuation of IV fluids after Critical phase • Co-morbid conditions
– congenital or ischaemic heart disease– chronic lung and renal diseases– Obesity – Fluid not calculated for IBW
![Page 53: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/53.jpg)
Early Clinical Features of Fluid Overload
• Respiratory distress– Difficulty in breathing– Rapid breathing– Chest wall in-drawing– Wheezing (rather than crepitations)
• Large pleural effusions &/or Tense ascites• Increased jugular venous pressure (JVP)
![Page 54: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/54.jpg)
• Minimize fluid– Stop if in recovery phase – Minimize in critical phase
• Nurse in the R lateral position• Maintain oxygen saturation above 95%• IV Furosemide +10% Dextran (40) 10 ml/kg ?• Correct hypokalaemia• Assess ABCS
Management of Fluid over load
![Page 55: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/55.jpg)
How to prevent fluid over load
• Try to manage within the fluid quota (M+5%)– For 48 hrs for non shock patients– For 24 hrs for shocked patients
• Expected Urine out put is only 0.5 ml/kg/hr• Calculate oral fluid also• Monitor fluid intake regularly during critical
period – Use a fluid monitor
Leaking Blood vessels ! – Give only minimal & essential

Fluid over load
Why?
![Page 65: Fluid Management in DHF Patients Dr Rasnayaka M Mudiyanse Senior Lecturer in Paediatrics Faculty of Medicine Peradeniya.](https://reader033.fdocuments.in/reader033/viewer/2022061305/5513fc3e550346d8488b46b8/html5/thumbnails/65.jpg)
Causes of fluid over load
• Clinicians gave too much fluid - eg 3-5 ml/kg/hr• Clinicians thought that extra fluid in the febrile
can prevent shock• Clinicians thought giving blood can be dangerous
Personal opinion with no proof
WHY ?
Lack of knowledge and training
