Four hundred and twenty-seven patients with severe blunt chest trauma were treated resulting in (1) flail chest, (2) pulmonary contusions, (3) pneumothorax, (4) hemothorax, or (5) multiple rib fracture. The need for endotracheal intubation and mechanical ventilation was determined selectively by standard clinical criteria. Avoidance of fluid overload and vigorous pulmonary toilet was attempted in all patients. Three hundred and twenty-eight patients were treated by nonintubation; 318 patients (96.6%) had a successful outcome, while ten required intubation. Only one patient died. The 99 patients who required intubation and mechanical ventilation had a high mortality because of associated shock and head injury; however, the total mortality for the entire group of patients was 6.5%, with only 1.4% mortality caused by pulmonary injury. The incidence of pneumonia was high (51%), but there was only a 4% incidence of tracheostomy complications. Flail chest and pulmonary contusion without flail chest occurred in 95 and 135 patients, respectively. Half of the flail chest patients were intubated, but 69.5% were intubated less than three days. Twenty per cent of the patients with pulmonary contusion required mechanical ventilation, usually for less than three days. This study demonstrates that patients with severe blunt chest trauma can be managed safely by selective intubation and mechanical, ventilation and that the incidence of complications associated with controlled mechanical ventilation can be greatly reduced.

Flail chest is associated with a higher morbidity compared with multiple rib fractures, and it requires early intubation. This was a prospective comparative uncontrolled study at an academic level 1 trauma center. Twenty-two patients with flail chest (FLAIL) were compared with 90 patients with more than two rib fractures but no flail chest (RIBS) to determine differences in outcomes such as mortality, significant respiratory complications (pneumonia and adult respiratory distress syndrome), need for mechanical ventilation, and length of hospital stay. Stepwise logistic regression identified independent risk factors of poor outcome. Despite similar age and rates of lung contusion and extrathoracic injury, FLAIL patients had a higher need for mechanical ventilation (86% versus 42%, P < 0.01), higher incidence of significant respiratory complications (64% versus 26%, P < 0.01), and longer hospital stay (28 +/- 21 versus 17 +/- 19 days, P = 0.04) compared with RIBS patients. Flail chest and extrathoracic injuries were independent risk factors of significant respiratory complications. Of 11 FLAIL patients who were not intubated on arrival, eight required intubation within the next 24 hours, often while receiving diagnostic studies in poorly monitored hospital areas; two of these patients suffered morbidity directly related to the delay in intubation. Three patients without associated injuries were managed successfully without intubation. Flail chest is an independent marker of poor outcome among patients with thoracic cage trauma. The majority of patients with flail chest need mechanical ventilatory support and develop significant respiratory complications. In the presence of associated injuries, intubation is unavoidable and should be done under controlled conditions early after arrival to avoid morbidity related to sudden respiratory decompensation.

Flail chest is an uncommon consequence of blunt trauma. It usually occurs in the setting of a high-speed motor vehicle crash and can carry a high morbidity and mortality. The outcome of flail chest injury is a function of associated injuries. Isolated flail chest may be successfully managed with aggressive pulmonary toilet including facemask oxygen, CPAP, and chest physiotherapy. Adequate analgesia is of paramount importance in patient recovery and may contribute to the return of normal respiratory mechanics. Early intubation and mechanical ventilation is paramount in patients with refractory respiratory failure or other serious traumatic injuries. Prolonged mechanical ventilation is associated with the development of pneumonia and a poor outcome. Tracheotomy and frequent flexible bronchoscopy should be considered to provide effective pulmonary toilet. Surgical stabilization is associated with a faster ventilator wean, shorter ICU time, less hospital cost, and recovery of pulmonary function in a select group of patients with flail chest. Open fixation is appropriate in patients who are unable to be weaned from the ventilator secondary to the mechanics of flail chest. Persistent pain, severe chest wall instability, and a progressive decline in pulmonary function testing in a patient with flail chest are also indications for surgical stabilization. Open fixation is also indicated for flail chest when thoracotomy is performed for other concomitant injuries. There is no role for surgical stabilization for patients with severe pulmonary contusion. The underlying lung injury and respiratory failure preclude early ventilator weaning. Supportive therapy and pneumatic stabilization is the recommended approach for this patient subset.

Blunt chest tramma is a major cause of mortality and morbidity following road side accident. An understanding of the factors affecting the mortality and morbidity will help in formulating better management strategies. The records of 40 consecutive patients presenting with blunt chest trauma (BCT) requiring ICU care from 1994-1996 were reviewed. Flail chest was the most common chest injury seen in 35 patients (87.5%). Isolated flail chest was seen in 22 patients, isolated pulmonary contusion in 2 patients and a combined injury in 13 patients. Ventilatory assistance was required in 34 patients (85%) for an average duration of 16 days (range 2-43 days). All patients with anterior flail required assisted ventilation in contrast to 75% and 88% of patients with unilateral and bilateral flail respectively. Presence of pulmonary contusion with or without flail was also associated with a high incidence of ventilatory support requirement. Chest infection (pneumonia) was the most common complication seen (65%). Adverse outcome occurred in 12 patients (30%). The main contributing factors for increased morbidity and mortality were: associated pulmonary contusion, associated extrathoracic injuries and preexisting medical illness. Statistical significance was observed only with pulmonary contusion.

Flail chest represents a severe injury with mortality historically reported at up to 30 per cent. Although management has changed dramatically over the past several decades, there is a paucity of large recent series. With Institutional Review Board approval, a retrospective review of all patients with flail chest admitted from January 2001 through May 2010 was undertaken. Patient demographics, outcomes, and cause of death were specifically analyzed with univariate and multivariate analysis. There were 164 patients at a median age of 51.4 years. Head injury and pulmonary contusion were present in 67 (40.8%) and 125 (77%), respectively. Pneumonia developed in 72 (43.9%). There were 41 deaths (25%), for which flail chest contributed to 15 (9.1%). Of the patients with flail chest-related death, the majority (n = 10 [66.7%]) died within 48 hours of presentation. There were only five deaths (3.0%) related to flail chest after 48 hours. Multivariate analysis of ventilator dependency revealed requirement for laparotomy (P = 0.019) or tracheostomy (P < 0.0001) and pneumonia (P = 0.0002) as significant. Pneumonia was the most significant independent predictor of overall (P < 0.0001) and intensive care unit length of stay (P < 0.0001). The mortality associated with flail chest has greatly improved; however, the rate of pneumonia remains high. Further efforts at pneumonia prevention are thus warranted.
