A
recent review [11] examined postoperative pulmonary morbidity and
found that the following clinical markers were predictive of respiratory failure
after noncardiac surgery: advanced age, ASA Grade
>
2
, functional depen-
dence, and a history of chronic obstructive pulmonary disease or congestive
heart failure, as well as high-risk procedures and serum albumin
<
3
0 g/L. The
relationship with smoking and obesity was inconclusive, and simple pulmo-
nary function tests were no better than clinical assessment.

Glasgow Coma Score (GCS), presence of cardiac signs, ECG abnormalities, an
y
respiratory problems, and key blood results) and 6 operative factors (urgency,
malignancy, peritoneal soiling, blood loss, reoperation, and severity o

A

h-risk patients havin

should be cared for postopera

tivel
y
in a critical-care environment. However, differences in the provision of
s
uch facilities make this infeasible and risks ur
g
ent cancer procedures bein
g
canceled. One solution has been the provision of an extended, overni
g
ht-sta
y
,
postanesthetic care unit with the facilities for HDU-level monitorin
g
and
nursin
g
. As discussed, CPX testin
g
provides a rational wa
y
of determinin
g
who will benefi
t most from limited resources and reduces the overall use of
c
ri
t
i
ca
l-
ca
r
e
beds.
W
here such facilities exist, GDT has been extended into the
p
osto
p
erative
period. Pearse et al. [25] anal
y
zed 122 hi
g
h-risk patients admitted to the ITU
postoperativel
y
. After randomization, the
y
performed GDT for a duration o
f
8 hours,
g
uided b

y
sis (LiDCO

g
for a D
O

f
600
mL mi

g
uid and the inodilator dopexamine when required. They demonstrated a
reduction in complications (44% vs 68%—mainl
y
cardiovascular and infec
-
tions) and median duration of hospital sta
y
(11 da
y
s vs 14 da
y
s), althou
g
h
there was no signifi
cant difference in mortality.
M
a
j
or sur
g
er
y
ma
y
be associated with a prolon
g
ed period of starvation,
with potentiall
y
deleterious consequences. A stud

vative regime of nasogastric decompression and feeding only after fi
rst passage
of fl
atus [26]. The protocol group had faster return to normal bowel function
and a shorter hospital sta
y
, with no increase in complications
.
Other aspects of the postoperative care are benefi
cial, including epidural
