The contribution of iatrogenic blood loss through diagnostic
testing to the
anaemia of critical illness remains controversial. We measured
the effect of an
arterial line blood conservation device upon blood loss and
anaemia in adult
intensive care patients. This randomized controlled trial
of 160 patients in a
major Intensive Care Unit (ICU) compared a blood conservation
device (Venous
Arterial Blood Management Protection Plus, VAMP Plus system,
Baxter Healthcare)
(VAMP group) to a standard arterial pressure line set attached
to an arterial
catheter (control group). The primary outcome measured was
the change in
haemoglobin concentration (Hb) during each patient's ICU admission
and the
volume of blood lost through diagnostic testing in ICU was
also recorded. Both
groups of 80 patients were matched for age, gender, severity
of illness (APACHE
II), baseline Hb on entry and ICU length of stay. Both groups
had a similar
(median [range]) change in Hb during ICU admission (VAMP-7
[-84 to +21] g/l;
Control -4 [-67 to +40] g/l; P = 0.33). The VAMP patients
lost significantly
less blood for diagnostic testing while in ICU (VAMP 63 [0
to 787] ml; Control
133 [7 to 1227] ml; P = 0.001). We conclude that the VAMP
Plus system
significantly reduced iatrogenic blood loss in critically
ill patients, but this
reduction did not affect the fall in Hb that accompanies critical
illness.

AIMS: To describe the clinical and health economic impact
of respiratory
syncytial virus (RSV) disease in children under 2 years of
age. METHODS:
Hospitalised children less than 2 years of age with a respiratory
illness were
studied over three consecutive RSV seasons (1996-99). RESULTS:
The rates (per
1000 infants under 1 year of age) of hospitalisations from
bronchiolitis and RSV
illness were 30.8 and 24.4 respectively. The rates of death,
intensive care
admission, and need for ventilatory assistance during RSV
related
hospitalisation were 0.2%, 2.7%, and 1.5% respectively. From
a cohort of 841
preterm infants, 6.3% had an RSV related hospitalisation during
the study
period, with the rate rising to 9.2% among those who were
either born before 36
weeks gestation and were under 6 months of age at the onset
of the RSV seasons,
or were less than 2 years of age with chronic lung disease
needing home oxygen
therapy. Eight of 25 children on home oxygen therapy had RSV
related
rehospitalisation. Need for assisted ventilation during the
neonatal period and
discharge home on oxygen therapy were significantly associated
with the risk of
subsequent RSV related hospitalisation in preterm infants
less than 6 months of
age. The direct health authority cost of all RSV hospitalisations
was pound 542
203, while the currently recommended immunoprophylaxis for
the high risk infants
would have cost pound 652 960. CONCLUSIONS: Preterm infants
receiving assisted
ventilation and those on home oxygen therapy are particularly
at risk of RSV
related hospitalisation. Serious adverse outcomes are however
uncommon even
among these high risk infants.

OBJECTIVE: To describe blood conservation strategies for
critically ill
patients. DATA SOURCES: By using a predefined strategy, we
searched the
electronic databases of Medline, EMBASE, CINAHL, the Cochrane
database of
systematic reviews, Cochrane central register of controlled
trials, ACP Journal
Club, Database of abstracts of reviews and effects, and HealthSTAR
for
descriptions and evaluations of strategies of blood conservation
among
critically ill patients. DATA SUMMARY: A number of blood conservation
strategies
have been used to prevent or treat anemia among critically
ill patients. These
include restrictive diagnostic phlebotomy using small-volume
or pediatric
phlebotomy tubes, point-of-care and inline bedside microanalysis,
minimization
of diagnostic sample waste, minimization of routine multiple
daily phlebotomies,
red blood cell salvage and antifibrinolytic agents for bleeding
patients,
consideration of removal of central venous and arterial catheters
when no longer
required for physiologic monitoring, threshold-based transfusion
policy, and
healthcare professional education. CONCLUSIONS: There are
many strategies of
blood conservation for critically ill patients. The effects
of these strategies
on phlebotomy volumes, hemoglobin and hematocrit levels, transfusion
requirements, clinical outcomes, as well as intensive care
unit and laboratory
resources and costs should be further evaluated.

New graduates a precious critical care resource.
Nibert AT.
College of Nursing, Houston Baptist University, Houston,
Tex., USA.
The shortage of nurses is here, and the complexity of the
issues involved will
take time to resolve. Undoubtedly, this process will be slow
and frustrating.
Critically ill patients who require intensive, highly skilled
nursing care are
among those most affected by the shortage of nurses. Nursing
service, in
partnership with nursing education, should create innovative
strategies that
will ultimately alleviate the shortage of nurses. What we
have to gain is more
precious resources, our new graduates filling all the chairs
in future summer
critical care orientation classes.

OBJECTIVE. To assess the levels of expression of the antiapoptotic
gene Bcl-2
and the proapoptotic gene Bax in circulating mononuclear cells
(CMNC) harvested
during the course of severe sepsis (SS) in formerly non-immunocompromised
patients undergoing hospital-acquired infection, in parallel
to cytokine levels.
DESIGN. Prospective study. SETTING. Intensive care unit. PARTICIPANTS.
A total
of 24 patients without immunodeficiency undergoing standard
goal-directed
therapy for nosocomial SS, 10 critically ill patients without
sepsis, and 10
healthy controls. INTERVENTIONS. Blood was collected before
infection and within
12 h, 1, 3 and 7 days after fever onset, to determine plasma
concentrations of
IL-6, IL-10, TNF-alpha, C-reactive protein, whole blood cell
counts, lymphocyte
subsets, annexin V labelling for apoptosis, and Bax and Bcl-2
relative RNA
expression by real-time polymerase chain reaction. RESULTS.
SS patients
displayed increased cytokine concentrations, TNF-alpha being
significantly
increased at full-blown sepsis. Within 12 h after onset of
infection, lymphocyte
counts were lower in SS patients than in critically ill controls
( p=0.001), and
this phenomenon was marked in CD4+ and CD8+ subsets ( p<0.001).
This was
associated with enhanced apoptosis in CMNC (15.7+/-8.7% vs
3.4+/-2.1%, p<0.001)
and a significant down-expression of the Bcl-2 gene throughout
the study (
p<0.05). In contrast, the expression of Bax did not change
significantly. Within
12 h of fever onset, non-survivors expressed a 10-fold down-expression
of Bcl-2
when compared to survivors ( p<0.001). CONCLUSIONS. An
early transient
down-expression of the gene Bcl-2 occurred in CMNC harvested
from SS patients
who died despite intensive care. In contrast, the expression
of the gene Bax did
not change significantly.

BACKGROUND: Damage control surgery (DCS) and treatment of
abdominal compartment
syndrome have had major impacts on care of the severely injured.
The objective
of this study was to see whether advances in critical care,
DCS, and recognition
of abdominal compartment syndrome have improved survival from
penetrating
abdominal injury (PAI). METHODS: The care of 250 consecutive
patients requiring
laparotomy for PAI (1997-2000) was reviewed retrospectively.
Organ injury
patterns, survival, and use of DCS and its impact on outcome
were compared with
a similar experience reported in 1988. RESULTS: Two hundred
fifty patients had a
positive laparotomy for PAI. Twenty-seven (10.8%) required
abdominal packing and
45 (17.9%) did not have fascial closure. Seven (2.8%) required
emergency
department thoracotomy and 21 (8.4%) required operating room
thoracotomy. Two
hundred seventeen (86.8%) survived overall. Small bowel (47.2%),
colon (36.4%),
and liver (34.4%) were most often injured. Mortality was associated
with the
number of organs injured (odds ratio, 1.98; 95% confidence
interval, 1.65-2.37;
p < 0.001). Vascular injury was a risk factor for mortality
(p < 0.001), as was
need for DCS (p < 0.001), emergency department thoracotomy
(p < 0.001), and
operating room thoracotomy (p < 0.001). Seventy-nine percent
of deaths occurred
within 24 hours from refractory hemorrhagic shock. DCS was
used in 17.9% (n =
45) versus 7.0% (n = 21) in 1988, with a higher survival rate
(73.3% vs. 23.8%,
p < 0.001). DCS was associated with significant morbidity
including sepsis
(42.4%, p < 0.001), intra-abdominal abscess (18.2%, p =
0.009), and
gastrointestinal fistula (18.2%, p < 0.001). CONCLUSION:
Penetrating abdominal
organ injury patterns and survival from PAI have remained
similar over the past
decade. Death from refractory hemorrhagic shock in the first
24 hours remains
the most common cause of mortality. DCS and the open abdomen
are being used more
frequently with improved survival but result in significant
morbidity.

Acute liver failure (ALF) is a rare clinical syndrome associated
with a
mortality of up to 80% and its management remains an interdisciplinary
challenge. Despite recent improvements in intensive care management,
the
mortality of patients with ALF remains high and is related
to complications such
as cerebral edema, sepsis and multiple organ failure. Emergency
orthotopic liver
transplantation (OLT) is currently the only effective treatment
for those
patients who are unlikely to recover spontaneously. Nevertheless,
OLT is not
always possible because of the shortage of the organs and/or
complications
related to ALF. Newly introduced liver-assist devices can
temporarily support
the patient's liver until native liver recovers or can serve
as a bridging
device until a liver graft is available. The support devices
use both cell-based
and non-cell-based techniques. One of the latest non-cell-based
extracorporeal
hepatic support devices, the molecular adsorbent recycling
system (MARS), is
based on the concept of albumin dialysis. MARS utilises selective
hemodiafiltration with countercurrent albumin dialysis aiming
to selectively
remove both water-soluble and albumin-bound toxins of the
low and middle
molecular-weight range. We report on a young patient who presented
with clinical
symptoms of ischemic hepatitis and multi-organ failure (APACHE
II score
38-->predicted postoperative mortality 87%) due to prolonged
hemorrhagic shock.
OLT was contraindicated because of history of pancreas cancer
with metastases.
It was necessary to use aggressive conservative therapy and
an extracorporeal
liver-assist device until liver regeneration began and hemodynamic
conditions
were stable. The patient underwent five treatments with MARS.
During the
treatment, there were improvements of hemodynamics, respiratory
function,
acid-base disturbances and laboratory parameters. The plasma
disappearance rate
of indocyanine green, a parameter of dynamic liver function,
improved during
MARS treatment. Although repeated neurological examination
predicted diffuse
brain damage (brain oedema, decreased cerebral blood flow),
the patient
recovered without any neurological deficits. The patient survived
and was
discharged from the hospital in good condition. In this case
MARS treatment was
successful in supporting the patient through the most critical
period of ALF.
