Abstract: deaeration chamber. Objective: To describe and count complications associated with continuous veno-venous hemofiltration (CVVH) in severely poisoned patients. Subjective: 139 times of CVVH in 106 severely poisoning patients were treated in the Poisoning Control Centre of Bach Mai Hospital from January 2007 to December 2011. Method: This was a descriptive study. Results: The average age was 35.6 + or - 14.1; Male/Female 1.46/1; 76.8 percent of patients were at the age from 20-59; 39.8 percent of causes for poisoning were chemical substances; the mortality rate was 35.8 percent; the main indication for CVVH was toxic elimination (31.1 percent); the most common technical error during CVVH was "cannot detect return" error (28.8 percent), "wrong access pressure" error was 21.6 percent; 7.2 percent of CVVH had hypotension during the first hour; thrombocytopenia was 3.6 percent; technical problems and complications were soon detected and corrected. Conclusion: The most common technical problem was "cannot detect return" error; CVVH-related complications were hypotension (5.7 percent) in the first hour and thrombocytopenia (3.6 percent). Strict monitoring and controlling the technical problems and complications of CVVH reduced risks during CVVH's progression.
