    Privacy Policy

    The European General Data Protection Regulation (GDPR) comes into force on May 25th 2018 and has major implications worldwide. European citizens now have multiple digital rights over their personal details, including the right to be asked to provide consent for the storage of personal details in a database, the right to be asked to provide consent to be contacted, the right to see the personal information stored, the right to be forgotten including having all personal details permanently removed from a database, the right to know who this information is shared with (consent is also required for this), and the right to be contacted should a significant data breach occur. All of these changes must be prospectively acknowledged by the user and cannot be presumed to have occurred. The proof rests with the websites to be able to demonstrate consent has been obtained. It is likely almost all websites in the world will move to this model, unless they wish to limit access to European citizens, which would be difficult technically. Fines for non-compliance with this can reach €20 million. As a result, we have updated our privacy policy accordingly. We took as example the updated privacy policy of Critical Care Reviews, a sister website providing FOAM content...

  • 7th IFAD 2018

    FIRST BATCH OF EARLY BIRD ONLINE REGISTRATIONS SOON OPEN

    November 23rd 2018
    Congress Centre "Pakhuis De Zwijger", Amsterdam, The Netherlands

    We are very pleased to announce the 7th International Fluid Academy Day, which will take place on November 23rd 2018 at Pakhuis De Zwijger in Amsterdam, The Netherlands. The aim of this seventh edition is again to review recent advances in fluid management, and hemodynamic and organ function monitoring in the critical care setting in a comprehensive manner for intensivists, anaesthesiologists and emergency physicians as well as interested internists and surgeons. However the meeting will deal with any broad topic related to critical care. As always it is also a great way to promote professional interaction between faculty members, participants and delegates of the industry. This website is regularly updated. Last modification by Adminstrator (Manu Malbrain) on February 7th at 10:00 AM.

  • About iFAD

    The iFAD started as local initiative form the pharmaceutical working group on fluids from the Ziekenhuis Netwerk Antwerpen (www.zna.be). Today iFAD is integrated within the not-for-profit charitable organization iMERiT, International Medical Education and Research Initiative, under Belgian law and as such the iFAD Organising Committee strongly recognizes and values a constructive partnership with the industry.

  • Brand new website!

    The IFAD website content is based on the philosophy of FOAM (Free Open Access Medical education – #FOAMed). The organising committee gives their time freely and receives no financial benefit. This in part explains the wonderful passions for philanthropy, sharing, education and innovation that make the IFAD unique.

The four questions of fluid therapy (Part 1.2.)

The four questions of fluid therapy (Part 1.2.)

Part 1.2. of series on fluid therapy

Why should I bother about the ebb and flow phase of shock? An illustrative case report

Question 1

At this stage, the participants of the ISICEM and IFAD meetings were asked the first multiple choice question (MCQ1): “Taking into account the results obtained with the transthoracic cardiac ultrasound, what is your treatment of choice at this stage?” Possible answers were: 1) norepinephrine; 2) dobutamine; 3) fluid bolus; 4) diuretics or 5) other. Figure 3 shows the results of the three votings. Based on the cardiac US findings physicians at ISICEM and iFAD seemed reluctant to fill the patient (only 6 to 13% stated to give a fluid bolus) and most of them were in favour of administrating dobutamine (39 to 64%).

Multiple choice question 1 (MCQ1): “Taking into account the results obtained with the transthoracic cardiac ultrasound, what is your treatment of choice at this stage?” Distribution of answers (in percentage) on MCQ1, blue squares denote the voting results of the ISICEM 2012 meeting, red squares show the results of the iFAD 2012 meeting, and green squares denote the voting results of the ISICEM 2013 meeting.

Further course

The FiO2 was increased to 100% and the PEEP was set according to the low flow pressure-volume (PV) loop (as can be automatically constructed with the Draeger Evita XL ventilator). Figure 4 shows the PV loop with detection of a lower inflection point at 16 cmH2O.

Fig4 PV loop

During the PV loop, that also acted as a recruitment maneuver his systolic blood pressure decreased to 40 mmHg, so norepinephrine was started and swiftly increased to 0.4 ug/kg/min. Dobutamine was also started at 4 ug/kg/min. Saturation remained poor at 88% and he was switched to high frequency percussive ventilation (HFPV) with the VDR4 ventilator (Percussionaire Corporation, Sandpoint, Idaho, U.S.A). A transpulmonary thermodilution PiCCO catheter (Pulsion Medical Systems, Munich, Germany) was inserted in the femoral artery at this point. The evolution of the hemodynamic parameters obtained after insertion of the PiCCO catheter together with the respiratory variables are listed in Tables 2 and 3. The initial hemodynamic picture showed a normal cardiac index (CI) of 3.5 L/min.m2 (normal range 3-5), a relatively low intravascular filling status with a GEDVI of 757 ml/m2 (normal range 680-800), a very low global ejection fraction GEF of 13%  (normal range 25-35) but a very severe capillary leak with high extravascular lung water index (EVLWI) of 38 ml/kg predicted body weight (normal range 3-7). The high EVLWI was suggestive of hyper permeability edema in view of the high pulmonary vascular permeability index (PVPI) of 7.4 (normal range 1-2.5) [16].

P/F: pO2 over FiO2 ratio
RR: respiratory rate
TV: tidal volume (ml)
VDR4: high frequency percussive ventilator
Vent: type of ventilator

At the same time however the patient seemed to be fluid responsive with a high pulse pressure variation (PPV) of 19% (normal range <10).  Heart rate was regular at 119 beats per minute with a MAP of 65 mmHg. The CVP was still 16 mmHg. His response to a passive leg raising (PLR) maneuver was positive (15% increase in CI and MAP) confirming that he was volume responsive despite the fact that he had such bad pulmonary edema (EVLWI 38) with a critical oxygenation status (P/F ratio of 57, at IPAP of 34 cmH2O and PEEP of 15 cmH2O).

Multiple choice question 2

At this stage, the participants of the ISICEM and IFAD meetings were asked the second multiple choice question (MCQ2): “Taking into account the results obtained with the transpulmonary thermodilution, what is your treatment of choice at this stage?” Possible answers were:
1) norepinephrine
2) dobutamine
3) fluid bolus
4) diuretics
5) other

    Fill in the petition. Guidelines that go beyond guidance and move to regimented, time-based prescriptions of care must be based on unassailable evidence. Even then, the clinician's assessment of the individual patient should allow a diversion from the guideline directed care.
