【 摘 要 】

Objective: To determine the socio-demographic characteristics, clinical profile and outcome of the tetanus patients.Study Design: Case SeriesPlace and duration of Study: SICU of Peoples University of Medical and Health sciences (PUMHS) Nawabshah,from January 2010 to December 2012.Methodology: The information obtained from the attendants of patients who presented with clinical features oftetanus and classified into generalized and cephalic types and; severity was classified into mild, moderate severe andvery severe. Treatment was started immediately with protocol of supportive care; neutralization of circulating toxinand eradication of the source of tetanospasmin. Details of socio-demographic data, clinical features, complicationsand outcome were recorded and entered in a questionnaire before analysis.Results: twenty two cases of tetanus were studied included males were 16 and females were 6. Six of 22 (27.3%)patients had prior tetanus immunization while the other sixteen (72.7%) patients were not vaccinated or did notknow their tetanus immunization status. Lower limbs were most common of portal of entry 15 (68.2%). Mostof patients (95.5%) have generalized tetanus and 5 (22.7%) patients had very severe disease. Body stiffness/spasm(100%), trismus (100%) and dysphagia (68.2%) were the three commonest presenting complaints. Complications oftetanus were documented in 16 (72.7%) patients. Overall mortality was 68.2 %.Conclusion: Tetanus prevalence is still high in interior Sind and is associated with high morbidity and mortality rate.
