Meticulousmedicaland nursingcareis
necessaryto managethesepatients.The
World Health Organisation(WHO) has
published guidelines highlighting the
errors commonly made in managing
thesepatientsat a district hospital.4In
our series,8 patients errors were found
that might have altered outcome. Some
patientshad more than one error in their
management;theseincluded a delay in
staring quinine therapy, using sulfadoxine-pyrimethamineinsteadinitially (3)
or no treatmentat all (l). This was
probably becausethe admitting medical
officer underestimatedthe severity of
the disease.In 5 patients there was a
failure to respond to a low plasma
glucose level. As hypoglycemia is a
frequent problem in patients with
malaria especiallyafter startingquinine
therapy,it is hospital policy to measure
fingerprick glucose6 hourly. Often this
is diffrcult to achieve when the wards
are full and thereis a shortageof nursing
staff. This task may be delegatedto the
most junior of staff who then do not

condition is improving and the parasite
loads are decreasinga.
Anaemia
The third most common causeof death
was anaemia.Ofthe 5 patientswho died
due to anemia,3 were babiesbelow l8
months.In fact, of the 6 children below
5 years who died of malaria, anaemia
was the causeof deathin 3 and possibly
associatedwith another one. In 2 of
thesepatientsanaemiawas not detected
early enough due to clinician error. In
these two patients no formal haemoglobin value was measuredalthoughthe
patients were noted to be pale. An
earlier checking of the haemoglobin
may have resulted in action that may
have altered the outcome. In one other
case anaemiawas recognised,with a
haemoglobinmeasurementof 2,2g/dl
but there was a delay in starting the
blood transfusiondue to nursingstaffing
problems.
Two adults died of anaemiain our
study. In one, who had in initial
haemoglobinof 10,lgldl, but was later
noted to be pale, an earlier transfusion
may have prevented death. In another,
a co existent haemolytic diseasewas
suspectedand earlier transfermay have
preventeddeath.This patient died with
a haemoglobinof 2,7 gldl.
Anaemia is a common presenting
feature of malaria in African children
and along with cerebral malaria makes
up the two most important complicationsof malariain children.aThe recommendation is to transfuse blood when
the haematocritdropsto below 20Yoand
to give this together with 20mg frusemide if the renal function is normala.
The rate and degree of anaemia
dependson the severity and duration of
the parasitaemia.It can either be due to
repeatedepisodesof malaria giving a
normocytic, normochromic picfure, or
from acute haemolysis with high
parasiteloads.Thesecasesoften present

to cerebralsigns and cardio pulmonary
signsa.
Renal failute
The fourth leading causeof death was
renal failure. A study of malaria deaths
in Durbanshowedthatpatientswho died
from renalfailure had a meancrea-tinine
of476 micromol./L,comparedto a mean
creatinineof 246 micromoVl in those
who survived with renal failure.'In our
28
study the mean creatinine of patients
who died from renal failure was 497
micromol/L. The Durban study found
that cerebral malaria and renal failure
were the most common causesof death
and had a much lower incidence of
deathsfrom pulmonaryoedemathan our
study. This may be becausein Durban,
ICU facilities areimmediatelyavailable,
or may be due to the fact that Durban is
a referral centre away from the at risk
areas.Many malaria patients seen in
Durban are in fact referrals from
outlying rural hospitalssuchas Manguzi
and so it may be that patients with
pulmonary oedemadie at thesehospitals
before reaching Durban.
Renal failure from malaria usually
occurs only in adults. The progression
is from deranged renal function, to
anuria to acute fubular necrosisa.It is
important to distinguish between pre
renal and intra renal failure. In the
former, fluid for rehydration should be
given, but cautiously to prevent
overload.
If the patient is anuric after
rehydration, the patient will need
dialysis. If the patient passessmall
amounts of urine after rehydration it
may be possible to maintain fluid
balance without dialysis. Fluid given
should be restricted to urine output and
insensible losses. Indications for
dialysis included metabolic acidosis,
hyperkalaemia, fluid overload and
clinical evidenceof uraemiaa.Progressive renal failure may require dialysis
or may improve as malaria is treated.
Haemodialysis is preferable to
peritoneal dialysisa.This is because
patients with malaria have decreased
flow of blood to the peritoneal cavity.
Peritonealdialysis has also been associatedwith high ratesof complications
and mortality in peripheralhospitals4.

The total casesin the district for the

CONCLUSION
Severalimportantlessonscanbe learned
from this study in how to better care for
critically ill patientswith malaria.These
include:
l. The importanceof startingquinine
early in patientswith severedisease.
2. The need to refer early to a tertiary
centre casesof pulmonary oedema
and worsening renal failure.
3. The importance of regularly
checking for anaemiaand the renal
function indicators.
4. The importanceof early blood transfusion in patients with a low
haemoglobin.
5. The importance of regularly
checking for hypoglycaemia in
patients on quinine therapy and in
taking the correct action when the
glucoseis low
Clinical audit such as this can help to
highlight these issues to hospital staff
in order to learn from their own
experience.D

OTHER
CAUSES OF DEATH
Other causesof death included multi
organ failure in an elderly man, and in
another patient, severe electrolyte
imbalance.In one patientco incidental
meningitis was suspectedbut a lumbar
puncturewas not done. In 3 patientsthe
causewas unknown.
In our study the increased number of
deaths seen during 1998/9 may be
relatedto severalfactors:
