Mechanical Ventilation in Patients Bitten by Bungarus Candidus

Abstract

Background: Bungarus candidus is a common accident, leading to respiratory failure due to respiratory muscle paralysis. Artificial ventilation is an essential intervention to cure. Objective: Assess results of artificial ventilation in patients bitten by Bungarus candidus. Subjects and Methods: The ventilation method is volume control with 2 different Vt levels: Vt 8-10ml/kg with PEEP 5cmH2O versus Vt 12-15ml/kg with out PEEP. To describe figures of ventilation, complication and microbiology causes of pneumonia. Results: 64 patients were put on ventilation. Average time of artificial ventilation was 9.8±7.1 days. Complications were due to ventilator-associated pneumonia (59.4%), the most common is Acinetobater baumanii 45%, followed by P. aeruginosa, K. pneumoniae, S. and Candida albicans. Complete recovery is 94%, sequelae is 3% and mortality is 3%. Sequelae and mortality mainly is due to respiratory failure and complications associated with mechanical ventilation. Conclusion: High Vt 12-15ml/kg mode is less atalectasis than Vt 8-10ml/kg with PEEP 5cmH2O. Complications mainly related to ventilator-associated pneumonia, the most common etiology is A.baumanii. Key words: Bungarus candidus, mechanical ventilation, respiratory muscle paralysis, complications.
