Tracheostomy timing in traumatic spinal cord injury

The study conducted is the retrospective study and the main objective is to evaluate the benefits and safety of early versus late tracheostomy in traumatic spinal cord injury (SCI) patients requiring mechanical ventilation. Tracheostomy offers many advantages in critical patients who require prolonged mechanical ventilation. Despite the large amount of patients treated, there is still an open debate about advantages of early versus late tracheostomy. Early tracheostomy following the short orotracheal intubation is probably beneficial in appropriately selected patients. It is a retrospective clinical study and we evaluated clinical records of 152 consecutive trauma patients who required mechanical ventilation and who received tracheostomy. The results show that the early placement (before day 7 of mechanical ventilation) offers clear advantages for shortening of mechanical ventilation, reducing ICU stay and lowering rates of severe orotracheal intubation complication, such as tracheal granulomas and concentric tracheal stenosis. On the other hand, we could not demonstrate that early tracheostomy avoids neither risk of ventilator-associated pneumonia nor the mortality rate. In SCI patients, the early tracheostomy was associated with shorter duration of mechanical ventilation, shorter length of ICU stay and decreased laryngotracheal complications. We conclude by suggesting early tracheostomy in traumatic SCI patients who are likely to require prolonged mechanical ventilation.     

Trachéotomie et traumatisme crânien grave : pour qui ? Pourquoi ? Quand ? Comment ?

The aim of this study is to determine, from the data available in the literature, the indications of tracheostomy in brain injured patients, the incidence and risk factors for complications and the follow-up required until decannulation. The incidence of tracheostomy is 10% in TBI and 50 to 70% in subpopulations with a Glasgow Coma Scale (GCS) below 9. Early complications are not specific. The most frequent late complication is laryngotracheal stenosis, which occurs in 15% and is more frequently observed in the most severe patients with major hypertonia. It is likely that tracheostomy, if needed, should be performed early and the prognosis as to whether it will be required, can be made at the end of the first week. The follow-up of these patients includes surveillance of multiresistant colonisations and systematic performance of fibroscopy before decannulation. Cuffless, small diameters, soft tracheostomy tubes, are preferred on the long-term unless the risk of aspiration remains high.     

Surgical tracheostomy versus percutaneous dilatational tracheostomy. A prospective-randomized study with long-term follow-up.

BACKGROUND: To compare surgical tracheostomy (ST) versus percutaneous dilatational tracheostomy (PDT) in terms of complication rates. In particular we specifically studied the late tracheal complications of both methods by means of endoscopic controls of patients up to 6 months after the procedures. METHODS: Design: prospective-randomized clinical study. Setting: University-affiliated tertiary care referral hospital. Patients: 50 consecutive translaryngeally intubated patients with respiratory failure were randomized to undergo either ST (25 patients) or endoscopic guided PDT (25 patients). RESULTS: ST was performed in 41+/-14 min versus 14+/-6 min for PDT (p<0.0001). There was no procedure-related death. In the ST group there were no intraoperative complications. In the PDT group 2 intraoperative complications (minor hemorrhages) were observed. In the ST group 9 early postoperative complications occurred: one minor bleeding, 7 stomal infections and one accidental decannulation. In the PDT group only one early postoperative complication (minor bleeding) occurred. Early postoperative complication rates were 36% for ST and 4% for PDT. In the ST group there were no late tracheal complications. In the PDT group 2 late tracheal complications (one segmental malacia and one stenosis at the level of the stoma) were observed. CONCLUSIONS: This study confirms that PDT is a simpler and quicker procedure than ST and that it has a lower rate of early postoperative complications. Late tracheal complications were more frequent, although the difference was not statistically-significant, in the PDT group. Further investigations of long-term outcome following PDT are therefore necessary.     

Early versus late tracheostomy in patients with severe traumatic head injury

BACKGROUND AND PURPOSE: A majority of patients with severe traumatic brain injury (TBI) need ventilatory support and require endotracheal intubation. There has been substantial debate regarding the timing of tracheostomy. We reviewed our data to determine the impact of early tracheostomy on our resources. STUDY DESIGN: Retrospective review of a consecutive series of patients with severe TBI treated at a Level II trauma center. METHOD: All 55 patients admitted to the surgical intensive care unit (ICU) with severe TBI from January, 2002 through September, 2005 were reviewed through the trauma registry. The inclusion criteria were severe TBI with a Glasgow Coma Scale (GCS) score < or = eight points at the time of admission and expected survival for longer than three days. All of these patients required mechanical ventilation and subsequently underwent tracheostomy. According to the timing of tracheostomy, subjects were classified as early group (< or = 7 days; N = 27) or late group (> 7 days; N = 28). The Wilcoxon rank sum test, the log-rank test, and Fisher exact tests were used to compare these groups. RESULT: The average time of the tracheostomy procedure was 5.5 +/- 1.8 (SD) days in the early group and 11.0 +/- 4.3 days in the late group. There were no significant differences between the groups in terms of age, proportion of female sex, GCS, Injury Severity Score, or need for blood transfusion. However, patients in the early group had a significantly shorter stay in the ICU than patients in the late group (19.0 +/- 7.7 vs. 25.8 +/- 11.8 days; P = 0.008). There was no difference between the groups in ventilator days (15.7 +/- 6.0 vs. 20.0 +/- 16.0 days; p = 0.57). There were no significant differences between the groups regarding overall mortality (15% vs. 4%; p = 0.19), incidence of pneumonia prior to tracheostomy (41% vs. 50%; p = 0.59), median total hospital length of stay (24 days vs. 28 days; p = 0.42), discharged to rehabilitation (74% vs. 82%; p = 0.53), or median total hospital cost (292,329 dollars vs. 332,601 dollars; p = 0.26). CONCLUSION: Early tracheostomy was beneficial, resulting in a shorter ICU stay.     

Aerodigestive injuries of the neck

Cervical aerodigestive trauma is rare and most centers have a limited experience with its management. The purpose of this review was to study the epidemiology, diagnosis, and problems related to the early evaluation and management of these injuries. This was a retrospective study based on trauma registry and on chart, operative, radiological, and endoscopic reports. There were 1560 admissions with blunt or penetrating trauma to the neck. The overall incidence of aerodigestive trauma was 4.9 per cent (10.2% for gunshot wounds, 4.6% for stab wounds, and 1.2% for blunt trauma). All patients with aerodigestive trauma had suspicious signs or symptoms on admission. The most common life-threatening problem in the emergency room and directly related to the aerodigestive trauma was airway compromise. Twenty-nine per cent of patients with laryngotracheal trauma required an emergency room airway establishment because of threatened airway loss. Although rapid sequence induction was successful in the majority of cases, in 11.9 per cent there was loss of airway and a cricothyroidotomy was necessary. Overall, 9 per cent of cases with aerodigestive injuries were successfully treated nonoperatively. Thirty-six per cent of patients with laryngotracheal trauma and surgical repair were successfully treated without a protective tracheostomy. There was no mortality due to the aerodigestive injuries. Cervical aerodigestive trauma is rare. In conclusion, all patients with significant aerodigestive injuries requiring treatment had suspicious signs and symptoms. Airway compromise was a common problem in the emergency room. Loss of airway after rapid sequence induction is a potentially lethal complication and the trauma team should be ready for a surgical airway. Repair of laryngotracheal injuries without a protective tracheostomy is safe in selected cases.     

Comparison of percutaneous dilatational tracheostomy with surgical tracheostomy

RATIONALE: Tracheostomy is done mostly in critically ill patients, many of whom may not survive. We still do not know the long term complications oftracheostomy itself; tracheal and subglottic stenosis, and tracheomalacia. OBJECTIVES: To compare the complications of surgical tracheostomy (ST) versus percutaneous dilatational tracheostomy (PDT) by means of MRI control up to 1 month after closed tracheostomy. RESULTS: There was no death related to tracheostomy. In both groups there were two preoperative complications: one minor hemorrhage and one subcutaneous empysema in the ST group, and one minor bleeding and one puncture ofendotracheal tube cuff in the PDT group. When the early and the late postoperative complications of the two groups were compared, it was observed that in the ST group, five early (one minor bleeding, three stomal infections and one accidental decannulation), and two late (one peristomal granuloma and one persistent stoma) postoperative complications had occurred. In the PDT group, four early (minor bleeding) and two late postoperative complications (two minor bleeding) were observed. MRI of two patients in the PDT group demonstrated tracheal stenosis. CONCLUSIONS: PDT is as safe and as effective as ST. Although the early and late postoperative complication rates were not significant in the PDT group, we believe that further investigations with larger groups are necessary to find long-term outcome following PDT. MRI scanning provides an excellent non-invasive method of assessing the tracheal lumen.     

Assessment of early tracheostomy in trauma patients: a systematic review and meta-analysis

The objective of this review was to assess outcomes in trauma patients undergoing early tracheostomy (ET). Abstract databases for the Eastern and American Associations for the Surgery of Trauma and Medline were searched to find trauma patient studies comparing ET and late tracheostomy (LT) or ET and no ET. Fixed-effects meta-analyses were performed on the randomized controlled trial (RCT) studies. Of five retrospective and four RCT studies, none demonstrated survival benefit or harm with ET (P > 0.05). In five RCT studies of ET and no ET, ET pneumonia rates were similar to the no ET group (relative risk 1.00 [95% confidence intervals 0.88-1.15], P = 0.97). In five RCT studies of ET and no ET, ET ventilator/intensive care unit (ICU) days were similar to the no ET group (P = 0.27). In the two severe brain injury studies, ET ventilator/ICU days were lower than the no ET group (P = 0.06). In the three nonbrain injury studies, ET ventilator/ICU days were similar to the no ET group (P = 0.79). Five studies described similar laryngotracheal pathology rates with ET and no ET or LT (P > 0.05). In conclusion, ET has no influence on mortality, pneumonia, or laryngotracheal pathology rates in trauma patients. Patients with severe brain injury may be more rapidly liberated from mechanical ventilation with ET. However, additional research is needed.     

The role of early tracheostomy in blunt, multiple organ trauma.

During a 9-year period, 101 patients sustaining blunt, multiple organ injury underwent tracheostomy. Group I consisted of 32 patients who underwent tracheostomy within the first 4 days of injury (early tracheostomy) and Group II comprised 69 patients who underwent tracheostomy more than 4 days after surgery (late tracheostomy). There was no statistical difference between the two groups in terms of age, Injury Severity Score, Glasgow Coma Score, and associated injuries. The mean time of mechanical ventilatory support was 6.0 +/- 3.4 days in Group I as compared to 20.6 +/- 12.2 days in Group II (P less than 0.001). Early weaning from the ventilator was accomplished in 32 (100%) patients who underwent early tracheostomy versus 43 (62%) of those who underwent late tracheostomy (P less than 0.001). Finally, the incidence of nosocomial pneumonias was also significantly less in patients undergoing early tracheostomy. There were three nonlethal complications associated with tracheostomy. The authors conclude that early tracheostomy helps in early weaning from the ventilator and reduces the incidence of nosocomial pneumonias and time of mechanical ventilatory support in patients with blunt, multiple organ injury.     

Management of penetrating laryngotracheal injuries

Background. Penetrating Iaryngotracheal injuries are uncommon; however, these injuries are associated with significant morbidity and mortality. In an attempt to define the management of penetrating laryngotracheal injuries, we reviewed our experience with these injuries. Methods. We retrospectively analyzed the records of all patients admitted to a Level I trauma center who required operative management for penetrating laryngotracheal injuries. During the period of this study all patients with penetrating neck injuries were managed according to a protocol of selective exploration. Results. Of fifty-seven patients with penetrating laryngotracheal injury 32 patients sustained gunshot wounds and 25 had stab wounds. The injuries were to the larynx in 24 (42%) and trachea in 33 (58%). Forty-six (81%) had isolated airway injuries and 11 (19%) had combined airway and digestive-tract injuries. Emergent airway management in 32 (56%) patients included: tracheostomy (15), endotracheal intubation (14), and cricothyroidotomy (3). Respiratory distress and subcutaneous crepitus were the commonest clinical findings. Diagnostic evaluation included: Iaryngoscopy/tracheoscopy (17), esophagoscopy (12), contrast esophagography (9), angiography (8), and bronchoscopy (3). Repair of laryngotracheal and esophageal injury was performed in the majority of patients. Selected patients with milder Iaryngotracheal injury did not have tracheostomy performed, with no increase in morbidity or mortality. There were 2 (3.5%) early deaths from associated major vascular injury. Conclusion. Mortality can be minimized by aggressive airway control. Endotracheal intubation can be accomplished safely in selected patients with penetrating laryngotracheal injuries. Digestive-tract injuries can often clinically occult and contribute significantly to morbidity and mortality; therefore, early evaluation of the esophagus is vital. Simple repair of Iaryngotracheal and digestive-tract injuries can be performed safely with good results. In patients with minor injuries, tracheostomy does not appear to be mandatory. © 1995 Jons Wiley & Sons, Inc.     

Parálisis bilateral tardía de cuerdas vocales trasintubación endotraqueal por neumonía COVID-19

Vocal cord paralysis is a rare but severe complication after orotracheal intubation. The most common cause is traumatic, due to compression of the recurrent laryngeal nerve between the orotracheal tube cuff and the thyroid cartilage. Other possible causes are direct damage to the vocal cords during intubation, dislocation of the arytenoid cartilages, or infections, especially viral infections. It is usually due to a recurrent laryngeal nerve neuropraxia, and the course is benign in most patients. We present the case of a man who developed late bilateral vocal cord paralysis after pneumonia complicated with respiratory distress due to SARS-CoV-2 that required orotracheal intubation for 11 days. He presented symptoms of dyspnea 20 days after discharge from hospital with subsequent development of stridor, requiring a tracheostomy. Due to the temporal evolution, a possible contribution of the SARS-CoV- 2 infection to the picture is pointed out.     

Acute penetrating neck trauma presenting with laryngotracheal injury

Laryngotracheal injuries are serious complications in the case of penatrating neck trauma which may not commonly in Japan. In the last several decades, many authors have discussed method for accurate evaluation and immediate airway management for patient with laryngotracheal injury. But, standardization of the treatment is still controversial about mandatory exploration or selective exploration. We report 4 cases with fresh laryngotracheal injury due to penetrating neck trauma including 3 suicide attempt patients. In these cases, laryngotracheoplasty used by absorbable material was performed within 8 hours after trauma. Two cases of suicide attempt patients underwent tracheostomy at the lower level of the laryngotracheal injury. After these treatment, fiberoptic bronchoscopy was performed to evaluate the airway for 3 cases except 1 who was dead because of hemorrhagic shock on arrival. In 2 cases, the suture filament existed in the lumen of the larynx and trachea, there were no major granulation in the site of repairment and no infection. Three cases were extubated successfully and discharged without major airway problem. Two cases have psychiatric disease such as depression, so we must consider their psychiatric background in the future. In conclusion, penetrating laryngotracheal trauma, we should consider that serious airway injury may be hidden under the superficial small wounds. Also, rapid local wound exploration and laryngotracheoplasty is important for life-saving, and fiberoptic bronchoscopy is effective to prevent early respiratory complications and has value in the evaluation.     

Percutaneous dilational and surgical tracheostomy in burn patients: Incidence of complications and dysphagia

The aim of this study is to evaluate the incidence of complications and dysphagia in relation to the timing of tracheostomy and tracheostomy technique in 49 consecutive adult burn patients. We analysed prospectively collected data. Bronchoscopy was used to diagnose tracheal stenosis and a modified Evans blue dye test was used to diagnose dysphagia. Eighteen patients received a percutaneous dilatational tracheostomy (PDT) and thirty-one patients received an open surgical tracheostomy (OST). Eight patients developed significant complications (16%) following tracheostomy, there is no difference in the incidence of complications; post op infection, stoma infection or tracheal stenosis between PDT and OST groups. Patients with full thickness neck burn who developed complications had a tracheostomy significantly earlier following autografting (p = 0.05). Failed extubation is associated with dysphagia (p = 0.02) whereas prolonged intubation and ventilation prior to tracheostomy independently predicts dysphagia (p = 0.03).     

Patterns of infection and mortality in thoracic trauma.

Tissue infection and systemic sepsis are common causes of morbidity and late mortality after major thoracic trauma. To seek causative mechanisms, prognostic indicators, and areas of possible improvement in therapy, we reviewed 310 consecutive adults admitted with major thoracic trauma. Of these, 56 (18%) died of massive injuries in the first 5 days; the remaining 254 were considered at risk for infectious complications. There were 21 late deaths in this group, and 15 (71%) were caused by systemic sepsis. Eighty-four patients (33%) developed thoracic infections, and 15 (6%) had significant nonthoracic infections. Markers of increased risk of infection included blunt injury, shock and unconsciousness on arrival, and splenectomy. Pulmonary infection was increased significantly following prolonged endotracheal intubation, but was virtually absent following tracheostomy. The risk of infection was increased significantly if prophylactic antibiotics were not used, but no definite correlation could be made to advanced age, pre-existent disease, nor post-traumatic malnutrition. Attention to some of these factors may decrease the risk of infection in thoracic trauma.     

The influence of tracheostomy timing on outcomes in trauma patients: A meta-analysis

ObjectiveThis study aims to assess the influence of tracheostomy timing on outcomes among trauma patients, including mortality, medical resource utility and incidence of pneumonia.MethodA systematic review of the literature was conducted by internet search. Data were extracted from selected studies and analyzed using Stata to compare outcomes in trauma patients with early tracheostomy (ET) or late tracheostomy (LT)/prolonged intubation (PI).Result20 studies met our inclusion criteria with 3305 patients in ET group and 4446 patients in LT/PI group. Pooled data revealed that mortality was not lower in trauma patients with ET compared to those with LT/IP. However, ET was found to be associated with a significantly reduced length of ICU and hospital stay, shorter MV duration and lower risk of pneumonia.ConclusionEvidence of this meta-analysis supports the dimorphism in some clinical outcomes of trauma patients with different tracheostomy timing. Additional well-designed randomized controlled trials (RCTs) are needed to confirm it in future.     

Complications after total thyroidectomy in thyroid carcinoma]

Authors report the postoperative complication rate in 52 patients who had undergone total thyroidectomy for cancer between 1984 to 1989. Total thyroidectomy has been performed in 9.8% of patients surgically treated for nodular thyroid pathology. Patients age average 49 years in a range 16-75; they were 49 women and 3 men. In 50% of cases we found papillary cancer, follicular in 40%, medullary 4% and anaplastic 6%. We shared postoperative complications in two mean groups: 1) aspecific complications as cardiocirculatory failure, respiratory failure, wound infections or collections, granulomas, keloids; 2) surgery related complications such as hypocalcemia, dysphagia, recurrent++ paralyses. The first group, we noticed just one case of respiratory mechanical failure due to severe tracheomalacia that required a temporary tracheostomy performed at the end of surgical procedure; we did not notice any death due to cardio-circulatory or respiratory failure, nor did we notice any postoperative hemorrhage; one patient presented a wound seroma, two patients presented granulomas due to subcutaneous stitches, and three developed papulous drug-induced erythema. The second group, eight patients developed a transient hypocalcemia beginning on the second postoperative day, without relevant tetanic crisis, well treated by calcium administration; only two of these patients developed permanent hypoparathyroidism. In 3 cases we had to perform exeresis of a laryngeal inferior nerve involved by the cancer, while in 5 more cases we noticed a transient monolateral paralysis that disappeared in 2 or 3 months. Three patients presented dysphagia before intervention and healed post-surgery.(ABSTRACT TRUNCATED AT 250 WORDS)     

Tracheostomy in children: there is a place for acceptable risk

BACKGROUND: Tracheostomy in children remains controversial regarding the risk of complications. METHODS: Forty-six trauma patients (35 male and 11 female, mean age = 6.8 years) were admitted to the intensive care unit between 1987 and 1991 with severe head injury plus coma. Tracheostomy was performed with standard technique after 5.9 days (range, 2-12 days) of intubation. RESULTS: There were no deaths from tracheostomy, but six deaths resulted from severe head injury. One child was discharged with tracheostomy. The 39 survivors remained with tracheostomy 16.14 days (range, 4-71 days) in the intensive care unit. After cannula removal, 31 remained asymptomatic; 8 had respiratory distress: 2 were normal, 5 had endoscopic treatment for subglottic granulomas/stenosis from intubation, and 1 had tracheomalacia from tracheostomy. In 1997, the 18 patients located for follow-up were asymptomatic. At endoscopy, 8 were normal, 9 had subglottal granulomas from intubation, and 1 had 20% tracheal stenosis from tracheostomy. CONCLUSION: Most complications after tracheostomy result from intubation. Tracheostomy has an acceptable risk in children with severe head injury who need prolonged ventilatory support.     

Airway Risk in Hospitalized Trauma Patients With Cervical Injuries Requiring Halo Fixation

OBJECTIVE: To identify the incidence and outcomes of emergent and semiemergent intubations in hospitalized trauma patients with cervical fractures and/or dislocations treated with halo fixation. SUMMARY BACKGROUND DATA: Intubating a trauma patient in halo fixation can be extremely difficult, with the potential for dire consequences. METHODS: The authors retrospectively reviewed the medical records of trauma patients with cervical injuries requiring halo fixation admitted to a level 1 trauma center between January 1992 and January 1997. The in-hospital need for emergent or semiemergent intubation was assessed and correlated with a variety of patient characteristics, including outcome. RESULTS: Of the 105 patients identified, 14 (13%) required an emergent or semiemergent intubation. Injury Severity Score, cardiac history, and intubation on arrival were significant indicators of the need for an in-hospital emergent or semiemergent intubation or reintubation. A total of seven deaths were reported, six of which were associated with an emergent or semiemergent in-hospital intubation. Although age did not appear significant in predicting the need for an emergent intubation, it was significant in predicting arrest-related deaths. A total of 17 tracheostomies were performed. Eight were considered "initial" in that they were performed before an emergent intubation, and nine were performed after an emergent intubation. Patients in the initial tracheostomy group did not differ in terms of the variables investigated from those who required an emergent intubation. None of the patients who underwent initial tracheostomy, however, had an airway emergency or died. CONCLUSIONS: A significant number of trauma patients treated with halo fixation ultimately require an in-hospital emergent or semiemergent intubation. Given the difficulty and potential lethality associated with these intubations, heightened vigilance regarding the airway is warranted. The authors recommend that early tracheostomy be considered in patients with a history of cardiac disease, especially when a high Injury Severity Score is present. Older patients (older than 60 years) are more at risk for arrest-related death and may also benefit from early tracheostomy.     

Submental intubation in complex craniomaxillofacial trauma

The submental route for endotracheal intubation is an alternative to nasal intubation or tracheostomy in the surgical management of patients with complex craniomaxillofacial injuries. The critical indication for submental intubation is the requirement for intraoperative maxillomandibular fixation (MMF) in the presence of injuries that preclude nasal intubation and in a situation where a tracheostomy is not otherwise required. MMF to re-establish dental occlusion is essential for a normal functional result in dentate patients with fractures involving alveolar segments of the jaws. However, MMF precludes orotracheal intubation. Nasotracheal intubation is often used but is contraindicated in the presence of skull base fractures and will interfere with the access to certain fracture types. A tracheostomy has a high potential complication rate and in many patients, an alternative to the oral airway is not required beyond the perioperative period. A submental intubation has been used in 11 selected cases amongst 190 consecutively treated patients with craniomaxillofacial trauma over a 3-year period. These cases have been retrospectively reviewed and there have been no significant complications. The indications and technique used are described. Submental intubation is a simple and useful technique with low morbidity in selected cases of craniomaxillofacial trauma and the author's clinical experience with this technique is described.     

Complications to Tracheostomy and Long-Term Intubation: A Follow-Up Study

Hospital records of 79 patients treated with tracheostomy or long-term intubation from 1969 to 1971 were reviewed, and the 43 surviving patients were examined by laryngoscopy, x-ray and spirometry for complications subsequent to these treatments. Early complications included one tube occlusion and one case of postextubation stridor in each group, one dislocated tube, one bilateral pneumothorax, and one case of fatal innominate arterial hemorrhage in the tracheostomy group, and two cases of atelectasis in the long-term intubation group. Necropsy findings included necrotic ulcers in the larynx of intubated patients and eroded tracheal mucosa in both groups. Late complications in surviving patients were prolonged hoarseness in six patients treated with prolonged intubation, two of whom had also had tracheostomy. Radiologically verified tracheal stenosis (40-60%), four at the stoma level and one at the cuff level, all occurred in the tracheostomy group.     

Influence of flail chest on outcome among patients with severe thoracic cage trauma

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.
