The aim of this study was to evaluate the epidemiological and clinical pattern and the prognosis of intramuscular injection.This is a retrospective study from the medical charts of 4 6 patients admitted for tetanus following intramuscular injection in the infectious diseases clinic ward of Fann hospital of Fann, in Dakar, between January 1999 and December 2002.PATIENTS AND METHODSThis is a retrospective study from the medical charts of 4 6 patients admitted for tetanus following intramuscular injection in the infectious diseases clinic ward of Fann hospital of Fann, in Dakar, between January 1999 and December 2002.The prevalence was 10% with a mean of 11.5 cases per year. The mean age was 34.5 years. The substance injected was known in 33 cases. Quinine injection was responsible in 32 cases. The period of onset was shorter than 48 hours in 39 cases (84.8%). The lethality rate was high (60.8%). The prognosis factors were the mean delay before h ospitalisation lower than 3 days (p = 0.03) and a scoring stage more than 4 (P = 0.01).RESULTSThe prevalence was 10% with a mean of 11.5 cases per year.

The effective prevention relies on the training of health care workers and the strict application of the Guidelines of the National Program against Malaria.CONCLUSIONTetanus following intramuscular injection is usually caused by quinine injection.
