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 realisethe urgencyof responding.Or the finger prick may not be taken at all. In two patients,Phenobarbitalsodium was not given prophylactically to prevent seizuresas per protocol at the time*. In one patient where featuressuspiciousof co existing meningitis existed,a lumber puncture was not done. 26 SA Fam Pract 2003;45(7) 4.; t r:1;*;r1?{t'rr;.illl; 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 with tachycardiaand dyspnoealeading 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. doctors were new or inexperienced. 2 . Crowdedwards led to problemswith nursingcare. The total casesin the district for the year were more althoughadmissions and casesseenin OPD were similar in numbersto previousyears. 4 . Difficulty in transfer. 5 . Logistics such as the lack of available blood, high care facilities etc. J. 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 Aclaowledgments I am grateful to Prof. I Couper and the staff of Manguzi hospital for their help in this study.This articleis basedon an assignmentthat was submitted for the Mastersin Family Medicine degreeat Medunsa. * 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: l.
