Abstract

Background: The aim of operative chest wall stabilization in patients with flail chest and respiratory insufficiency is to reduce ventilator time and avoid ventilator associated complications. The purpose of this retrospective study was to analyze the indications and outcomes of operative chest wall stabilization in defined groups of patients sustaining flail chest with and without pulmonary contusion.

Methods: The hospital records of 405 patients with multiple trauma (Injury Severity Score > 17) between 1988 and 1994 were reviewed. Forty-two patients sustained flail chest. Twenty of these underwent operative chest wall stabilization for the following indications: 1) flail chest with indication for thoracotomy due to intrathoracic injury (n = 6); 2) flail chest without pulmonary contusion (n = 9); 3) paradoxical movement of a chest wall segment in the weaning period from the respirator (n = 3); and 4) severe deformity of the chest wall (n = 2). For the purpose of analysis the patients were separated into groups: group 1: operative chest wall stabilization in flail chest without pulmonary contusion (n = 10); group 2: operative chest wall stabilization in flail chest with pulmonary contusion (n = 10); group 3: flail chest without pulmonary contusion and without chest wall stabilization (n = 18); group 4: flail chest with pulmonary contusion and without chest wall stabilization (n = 4). Data were coded for time of operation, duration of ventilatory support, and complications.

Results: There were no significant differences in age, severity of injury, and extent of injury between groups 1, 2, and 3 (p < 0.42). Group 4 was excluded for statistical analysis because of the small number of patients. Patients in group 1 required a shorter ventilatory support time compared to patients in group 3 (6.5 ± 7.0 versus 26.7 ± 29.0 days) and group 2 (p < 0.02). In group 2 (ventilator time 30.8 ± 33.7 days) early extubation was only possible in patients being operated on for chest wall instability during weaning from the ventilator. One patient in group 1, three patients in group 2 and five patients in group 3 developed pneumonia with further disturbance of gas exchange. All patients in group 1 survived; deaths in group 2 were attributed to massive hemorrhage in two and septic multiorgan failure in one patient. Four patients in group 3 died of head injury, one of acute respiratory distress syndrome, one of severe hemorrhage, and one of multiple organ failure.

Conclusions: In patients with flail chest and respiratory insufficiency without pulmonary contusion, operative chest wall stabilization permits early extubation. Patients with pulmonary contusion do not benefit from chest wall stabilization. Secondary operative chest wall stabilization in these patients is indicated when progressive collapse of the chest wall is evident during weaning from the ventilator.

Methods

The hospital records of 405 consecutive patients with multiple trauma (Injury Severity Score [ISS] > 17) including patients with isolated severe blunt chest trauma (Abbreviated Injury Scale [AIS]-thorax ≥ 3) primarily admitted to the Department of Trauma Surgery, University Hospital Essen, Germany between 1988 and 1994 were reviewed (ISS 25.5 ± 10.0). Two hundred and ninety-five (out of 405) of these patients (ISS 26.7 ± 10.0) sustained severe blunt chest trauma AIS thorax 3.4 ± 0.6). Forty-two

Extent of injury

Group 1: The mean ISS was 31.0 ± 7.0 (range, 24–41). Only one patient sustained isolated blunt chest trauma; all other patients had multiple injuries. The major diagnosis was blunt chest trauma demonstrated by a mean AIS-thorax of 4.1 ± 0.3 (range, 4–5). Associated injuries were injuries of the head (AIS 1.7 ± 1.3 [range, 0–3]), of the abdomen (AIS 1.7 ± 1.6 [range, 0–4]), of the extremities (AIS 1.6 ± 2.6 [range, 0–4]), and of the face (AIS 0.9 ± 1.6 [range, 0–4]). The most common associated

Discussion

Despite improved methods in intensive trauma care and advanced techniques in mechanical ventilation, mortality of patients with flail chest remains quite high.4, 13 To avoid the well known complications of longterm ventilation, internal pneumatic stabilization should be avoided. Local pain relief (epidural analgesia), chest physiotherapy (mask continuous positive airway pressure [CPAP]) and removal of pulmonary secretions are essential in management of flail chest without ventilatory support.

Conclusions

  • 1.

    Flail chest without pulmonary contusion necessitating ventilatory assistance despite sufficient analgesia and mask-CPAP from persisting hypoxemia seems to be a rational indication for operative chest wall stabilization in patients without severe head injury. Early operative chest wall stabilization within 48 hours permits extubation after a mean ventilator time of 6.5 days.
