Résumé
Objective: To determine the frequency of Hyperamylasemia leading to respiratory failure in patients of organophosphate poisoning
Study Design: Observational / descriptive study
Place and Duration of Study: This study was conducted at the Department of Medicine Dow University of Health Sciences, Karachi from June 2014 to June 2015
Materials and Methods: A total of 168 patients of Organophosphate poisoning fulfilling the inclusion criteria were included in the study. Blood was drawn after aseptic measures by a trained phlebotomist for Serum Amylase level and Arterial blood gases. Value more than 101U/L was taken as hyperamylasemia. PaO[2] less than 60mmHg or PCO[2] greater than 55mg was labeled as respiratory failure. All information was noted on proforma
Results: There were 59% were male and 41% were female. Frequency of hyperamylasemia in patients of organophosphate poisoning was 44%. Frequency of respiratory failure in hyperamylasemia in patients was observed in 68%. Respiratory failure was significantly high in male than female [70% vs. 30%; p=0.019]
Conclusion: Hyperamylasemia is more frequently seen in organophosphate poisoning. In patients with respiratory failure the mortality is very high; therefore we recommended early diagnosis, careful monitoring and appropriate management of complications in reducing the mortality rate
