Clinical research on breath failure induced by acute tetramine poisoning / 解放军医学杂志

ABSTRACT

Objective To find the correlative factors which induce breath failure in acute tetramine poisoning cases, and to work out a right treatment scheme for these cases. Methods 47 cases were clinically diagnosed as slight, middling and severe poisoning, separately. The tetramine concentration in blood was compared between the three groups to reveal the relationship between blood concentration of tetramine and breath failure. Patients with breath failure were treated with muscle relaxant plus mechanical ventilation. Repeated hemoperfusions were given to the severe poisoning patients. Results No breath failure occured in both slight and middling groups, while in severe poisoning group, breath failure happened in 33.3% (4/12) patients aged below 15, and in 31.8% (7/22) adult patients aged above 15. Repeated hemoperfusion declined the tetramine concentration in blood, and gave a better effect than with CVVH or CVVHD treatment. muscle relaxant plus mechanical ventilation may control the symptom of twitching completely, and prevent from breath failure effectively. Conclusion Breath failure in acute tetramine poisoning cases was induced by systemic twitching and high blood tetramine concentration. It is very important to grade the poisoning cases according to poisoning degree. Repeated hemoperfusion is the best for blood purification. muscle relaxant plus mechanical ventilation may reduce the mortality effectively.
