Administering intravenous 1047298uids to support the circulation in critically ill patients has been a mainstay of
emergency medicine and critical care for decades especially (but not exclusively) in patients with distributive
or hypovolemic shock However in recent years this automatic use of large 1047298uid volumes is beginning to be
questioned Analysis from several large trials in severe sepsis andor acute respiratory distress syndrome have
shown independent links between volumes of 1047298uid administered and outcome conservative 1047298uid strategies
have also been associated with lower mortality in trauma patients In addition it is becoming ever more clear
thatcentral venouspressure which is often usedto guide1047298uidadministration is a completely unreliable param-
eter of volume status or 1047298uid responsiveness Furthermore 2 recently published large multicenter trials (ARISE
and ProCESS) have discredited the ldquoearly goal-directed therapyrdquo approach which used prespeci1047297ed targets of
central venous pressure and venous saturation to guide 1047298uid and vasopressor administration This article dis-
cussesthe risks of ldquoiatrogenic submersionrdquo andstrategiesto avoid this riskwhilestillgivingour patients the1047298uids
they need The key lies in combining good clinical judgement awareness of the potential harm from excessive
1047298uid use restraint in re1047298exive administration of 1047298uids and use of data from sophisticated monitoring tools
such as echocardiography and transpulmonary thermodilution Use of smaller volumes to perform 1047298uid
challenges monitoring of extravascular lung water earlier use of norepinephrine and other strategies can help
further reduce morbidity and mortality from severe sepsis

One of the most challenging and controversial areas in the care of
emergent and critically ill patients is the administration of intravenous
1047298uids to support the circulation This does not only apply to hemody-
namically unstable patients In clinical conditions such as subarachnoid
hemorrhage large volumes of 1047298uid are often administered over
prolonged periods to reduce the risk of vasospasm often targeting a
positive 1047298
uid balance or a speci1047297
c central venous pressure (CVP) [1]However especially when a patient presents with a distributive or hy-
povolemic shock rapid administration of 1047298uids is one of the mainstays
of treatment one that has been recommended for decades This applies
to both the initial and later phases of treatment especially in distribu-
tive shock The 2012 ldquoSurviving Sepsis Campaignrdquo guidelines recom-
mend an initial 1047298uid challenge followed by continued 1047298uid
administration if hypotension persists or blood lactate concentration
exceeds 4 mmolL [2] Again CVP is often used to guide 1047298uid volume
this in spite of abundant evidence showing that CVP is completely un-
reliable as a parameter of volume status or 1047298uid responsiveness [2-5]
In 2001 a highly in1047298uential single-center study reported that 1047298uid
and vasopressor administration using prespeci1047297
ed targets including aCVP of 8 to 12 and venous saturation greater than 65 in the 1047297rst
6 hours of sepsis could reduce mortality by 158 [6] This approach
was termed early goal-directed therapy (EGDT ) [6] Recently 2 large
multicentered studies (the ProCESS trial and the ARISE trial) failed to
demonstrate any bene1047297ts of the EGDT approach [78] in spite of this
current guidelines still recommend EGDT and a recent statement on
behalf of the ldquoSurviving Sepsis Campaignrdquo panel put out after publica-
tion of the ProCESS trial suggests that no change in guidelines will be
forthcoming because ldquothe ProCESS trial used protocolized care in all
study groupsrdquo and thus its negative 1047297ndings ldquodo not invalidate the
EGDT approachrdquo [9]

However in recent years a number of studies in emergency medi-
cine and critical care have raised concerns over the practice of unre-
strained 1047298uid administration that has become so ingrained in daily
practice One of the 1047297rst studies to address this issue was a clinical
trial in children performed in Africa designed to compare 1047298uid bolus
of albumin to normal saline with the hypothesis that albumin adminis-
tration might improve outcome in sepsis [10] Children receiving nor-
mal saline and albumin 1047298uid bolus had similar outcomes but
mortality was signi1047297cantly lower in children who had not receivedany 1047298uid bolus [10] As the study had been performed in poor countries
in Africa there were questions regarding the applicability of these 1047297nd-
ings to industrial countries with modern health care systems The
causes of infection disease course time to medical treatment health
care delivery systems preexisting conditions and many other factors
are very different in Africa compared to Western countries Although
these criticisms are valid other reports support the initial observations
and lend credence to the hypothesis that excessive1047298uid administration
can be detrimental A post hoc analysis of the acute respiratory distress
syndrome network (ARDS-NET) showed that a negative cumulative
1047298uid balance at day 4 was associated with signi1047297cantly lower mortality
independent of other measures of severity of illness including a diagno-
sisof sepsis [11] This observation wascon1047297rmed inanother studyof pa-
tients with acute respiratory distress syndrome (ARDS) secondary toseptic shock [12] In fact in this study patients receiving 1047298uid manage-
ment considered ldquoinadequate but conservativerdquo had better outcomes
than 1047298uid administration considered ldquoadequate but liberalrdquo [12] Simi-
larly in the Vasopressin vs Norepinephrine Infusion in Patients with
Septic Shock trial a more positive 1047298uid balance both early in resuscita-
tion and cumulatively over 4 days was associated with increased risk
of mortality in septic shock corrected for other factors [13]
This does not just apply to sepsis A recent meta-analysis of random-
ized controlled trials and cohort studies and cohort studies found that
conservative 1047298uid strategies were associated with lower mortality in
trauma patients [14] In addition it is not only unrestrained crystalloid
infusion that is being called into question a recent study reported that
transfusion of red blood cells was associated with signi1047297cantly worse
outcomes in patients with traumatic brain injury and no evidence of
shock if the initial hemoglobin was greater than 10 gdL [15] Twenty
years ago Bickell et al [16] challenged the practice of early 1047298uid resusci-
tation in patients with penetrating injuries suggesting that this practice
might be linked to increased bleeding and adverse outcomes This issue
still remains controversial [17]
In this issue of The American Journal of Emergency Medicine Sirvent
[18] reports on the effects of 1047298uid administration at the onset of severe
sepsis and septic shock The author found that the accumulated positive
1047298uidbalance in the1047297rst 48 72 and 96hours wassigni1047297cantly associatedwith increased mortality [18] These results are in keeping with the re-
sults discussed above and remind us again of the risks of ldquoiatrogenic
submersionrdquo How can we avoid this risk while still giving our patients
the 1047298uids that they may need
In our view the key lies in a multipronged approach using clinical
judgment along with sophisticated monitoring tools to guide our treat-
ment The 1047297rst step is awareness and restraint awareness that exces-
sive 1047298uid administration could be harmful and restraint in the
restraint in there1047298exive administration of 1047298uids If a patient does not re-
spond to a bolus of 1047298uid we should think twice before giving yet more
1047298uids or trying yet another 1047298uid challenge instead we might consider
earlier initiation of pressors or perhaps accepting less ambitious target
values Especially we should not target speci1047297c CVPs to guide treat-
ment rather a combination of clinical and biochemical parametersand more sophisticated hemodynamic monitoring (echocardiography
cardiac output extravascular lung water [EVLW] and stroke volume
variation) can be used to better tailor our therapeutic approach (see
Table) Fluid responsiveness can be assessed with smaller volumes
(100-250 mL administered rapidly rather than 500-1000 mL as is com-
mon practice) Monitoring of EVLW may be a valuable safety parameter
to prevent 1047298uid overload A recent study in ARDS patients suggests that
high EVLW is an independent risk factor for mortality in ARDS [19] This
approach may also apply to less sick patients to take the earlier exam-
ple of subarachnoid hemorrhage a recent randomized controlled trial
reported signi1047297cantly improved outcomes using preload volume and
cardiac output (monitored by transpulmonary thermodilution) to
guide treatments compared to patients where ldquotraditionalrdquo parameters
such as 1047298uidbalance and CVP were used [20] Noninvasive devices such

as continuous wave Doppler ultrasound cardiac output monitoring may
also have a useful role in cardiac output monitoring [2122]
Mortality was signi1047297cantly lower in all arms of the ProCESStrial than
in the initial EGDT study [67] In the EGDT arm of the ProCESS trial the
use of vasopressors in the1047297rst 6 hours wasdouble (549 vs 274) and
thevolume infused in the1047297rst 72 hourshalf(722 vs 1344 L) compared
to theEGDT studyThis suggests that more restrictive1047298uid management
is feasible even when using a judicious EGDT approach We urge the
readers to take to heart the important lessons of Sirvent and from previ-
ous trials and not to use too much of a good thing

as continuous wave Doppler ultrasound cardiac output monitoring may
also have a useful role in cardiac output monitoring [2122]
Mortality was signi1047297cantly lower in all arms of the ProCESStrial than
in the initial EGDT study [67] In the EGDT arm of the ProCESS trial the
use of vasopressors in the1047297rst 6 hours wasdouble (549 vs 274) and
thevolume infused in the1047297rst 72 hourshalf(722 vs 1344 L) compared
to theEGDT studyThis suggests that more restrictive1047298uid management
is feasible even when using a judicious EGDT approach We urge the
readers to take to heart the important lessons of Sirvent and from previ-
ous trials and not to use too much of a good thing
