AbstractA better understanding in pathophysiology of flail chest has brought an evolution to the principles of it's management. The methods of stabilization changed from surgical to pneumatic measures and now, a concept of conservative treatment is recognized. Adhering to our protocol for flail chest, which essentially limits mechanical ventilation, we have prospectively treated 36 patients since 1981. The patient were divided into two groups according to their need for mechanical ventilation. There were 16 patients (44.4%) in a group treated in conservative manner and with no mechanical ventilation (Group A). There were 20 patients (55.6%) in a group treated by mechanical ventilation (Group B). Group A had 6.2% incidence of pneumonia, 3.6 days average stay in ICU and mortality rate of 0%. Group B had 75% pneumonia, 22.5 days average in ICU and 15% mortality. Group B patients required respiratory support for 14 days average, which was not reduced by surgical stabilization. Restrictive pulmonary disturbance in group A was milder than that of group B, and this again was not affected by surgical stabilization. We conclude that 40% of flail chest are controllable without mechanical ventilation and that the result of this conservative therapy is superior to any other treatments.
