Respiratory complications developed in 22 patients (8.1%), and the remaining 2 patients (0.74%) had reabsorption syndrome. Six cases of severe complications developed (2.22%), i.e.: one electromechanical dissociation, one ventricular tachycardia, one reabsorption syndrome and two severe difficulties for ventilation.
