Percutaneous versus Conventional Tracheostomy in Burned Patients with Inhalation Injury

The aim of the study was to compare conventional tracheostomy with percutaneous dilatational tracheostomy in patients with inhalation burn injury. A total of 37 patients with severe burn injuries and associated inhalation injury, underwent percutaneous tracheostomy in our burn unit and were retrospectively compared with 22 patients who underwent conventional surgical tracheostomy. In the first group, 25 of 37 patients and in the second group 17 of 22 patients presented with partial or full-thickness burn injuries (or both) in the neck region. The cost of the procedure, operating time, complications, and incidence of pulmonary infection were recorded. There were no significant perioperative complications in the percutaneous tracheostomy group, and no patient required surgical revision or conversion to surgical tracheostomy. In the conventional tracheostomy group, 2 patients developed tracheal stenosis, 1 had a tracheoesophageal fistula, and 10 had stomal infections. The average procedure time in the first group was 9 minutes, and in the second group it was 22 minutes. The cost of the bedside percutaneous tracheostomy was one-fifth the cost of a conventional tracheostomy. The incidence of pulmonary sepsis was 45% after percutaneous tracheostomy compared to 68% after conventional tracheostomy. With the percutaneous technique, spontaneous closure of the stoma occurred within 1 to 3 days after removal of the tracheostomy tube, whereas with the conventional technique it was within 5 to 7 days. Percutaneous tracheostomy is associated with a lower complication rate and can be safely performed at the bedside. Moreover, it is faster and can be done at a lower cost than conventional open tracheostomy.     

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.     

Management of airway trauma. I: Tracheobronchial injuries

One hundred six consecutive patients with injuries to the tracheobronchial tree who were admitted to the emergency room of the Tulane Medical Center Hospital or the Charity Hospital of Louisiana at New Orleans over a period of almost 20 years were analyzed retrospectively. Penetrating trauma of the neck or chest was reported in 100 of the patients, and only 6 had blunt trauma to the neck or thorax as the cause of injury. There were 18 deaths among the 106 patients (16.98%), including 11 (13.75%) of 80 with injuries of the cervical trachea. Seven (53.8%) of 13 with principal injuries of the thoracic trachea died; all 13 patients with major bronchial injuries survived. On admission to the emergency room, all patients had signs of airway compromise such as tachypnea, dyspnea, cyanosis, subcutaneous emphysema, or an abnormal respiratory pattern. Severe airway compromise was evident in 46 patients; 24 (23%) were treated with oral or nasal intubation, 19 (18%) with emergency tracheostomy, and 3 (2%) with intubation of a tracheal injury. Hemoptysis was an unreliable signal of serious injury, being present in only 28 of the patients. Patients who had major vascular injuries combined with trachea involvement were generally not salvageable. In regard to morbidity and mortality, the most common preventable errors were delay in diagnosis and treatment of tracheobronchial injuries, missed esophageal injuries, massive aspiration of blood, and abdominal vascular injuries.(ABSTRACT TRUNCATED AT 250 WORDS)     

Percutaneous tracheostomy/gastrostomy in brain-injured patients--a minimally invasive alternative.

Tracheostomy and gastrostomy are frequent adjunctive procedures required in the management of patients with severe brain injuries to facilitate neurorehabilitation. We therefore evaluated the use of two minimally invasive surgical procedures, percutaneous tracheostomy (PT) and percutaneous endoscopic gastrostomy (PEG), in 27 patients with severe brain injuries. The mean age was 41 +/- 4 years, and 23 (85%) were men. All patients were intubated, and 19 (70%) required mechanical ventilator support on the day of PT/PEG. The endotracheal tubes had been in place for 1 to 21 days (mean, 8.7 +/- 0.8). All patients were stable from their acute brain injury; 13 had intracranial pressure (ICP) monitors in place. The Seldinger technique, as described by Ciaglia, was employed for PT. Following PT, a PEG was inserted by a modification of the Sachs-Vine "push" technique. We were uniformly successful in placing these access tubes. Complications were minor and not clinically significant. Three of 13 patients (23%) with ICP monitors had a transient rise in ICP related to PT and one of these patients developed local subcutaneous emphysema. Another patient experienced a mild cellulitis at the tracheostomy site. Of note, there were no PEG-related complications. In conclusion, PT and PEG are readily learned, minimally invasive procedures. In our experience with patients with severe brain injuries combined PT/PEG is a uniformly safe alternative to gain long-term access to the airway and gut.     

Is early tracheostomy safe in cardiac patients with median sternotomy incisions?

BACKGROUND: Tracheostomy after cardiac operation through a median sternotomy is believed to increase the risk of mediastinitis, leading to debate as to whether early tracheostomy is safe in these patients. METHODS: A record search of patients undergoing cardiac operation through median sternotomy was done. Day and duration of tracheostomy were correlated to day of positive bacteriological evidence and clinical outcome for the patient. The method of tracheostomy was also recorded. RESULTS: Of 174 cases, 4 patients had mediastinitis, 3 before tracheostomy was performed. Of these three patients, 2 survived and the third died of multiorgan failure 46 days after the procedure. The fourth patient, on immunosuppressive therapy for severe rheumatoid arthritis and pulmonary fibrosis, had tracheostomy performed at primary operation, developed fatal mediastinitis after 6 days, and died 18 days postoperatively of multiorgan failure. Of the tracheostomies performed, 24 (14%) were percutaneous, and 110 (63%) were achieved using standard surgical techniques (in 40 cases type was unrecorded). In 72 cases (41%), tracheostomy was performed on or before day 7, 11 (6%) being performed before 48 hours. Mortality occurred in 38 (22%). CONCLUSIONS: There is no demonstrable relationship between early tracheostomy and mediastinitis in median sternotomy patients.     

Contemporary assessment of laryngotracheal trauma

OBJECTIVES: Laryngotracheal trauma is a rare and potentially deadly spectrum of injuries. We sought to characterize the contemporary mechanisms, diagnostic modalities, and outcomes common in laryngotracheal trauma today. METHODS: We performed a retrospective analysis of all laryngotracheal trauma cases at 2 major metropolitan hospitals between 1996 and 2004, detailing mechanisms, associated injuries, diagnostic modalities, and outcomes of laryngotracheal trauma. RESULTS: We identified 71 patients with a mean age of 32.8 +/- 13.3 years (range, 15-71 years). In our series penetrating trauma was the cause in 73.2% of patients; however, blunt trauma had a significantly higher mortality (63.2% vs 13.5%, respectively; P < .0001). Blunt mechanisms involved older patients (38.5 +/- 15.2 years vs 30.1 +/- 11.9 years, P = .017), and these patients were more likely to require emergency airways than those with penetrating trauma (78.9% vs 46.2%, P = .017). The requirement of an emergency airway was an independent predictor of mortality (P = .0066). CONCLUSION: Laryngotracheal trauma is a deadly spectrum of injuries with a mortality of 26.8%. Blunt mechanisms are decreasing in frequency. This might reflect improvements in automobile safety. Additionally, violent crime is on the increase, producing penetrating injuries with increasing frequency. The most fundamental intervention for patients with laryngotracheal injury is airway control. Either routine intubation or a tracheostomy can secure the airway. Blunt trauma and the requirement of an emergency airway are independent predictors of mortality. Laryngotracheal trauma requires prompt recognition, airway protection, and skillful management to lessen the mortality of this deadly spectrum of injuries.     

Chest trauma in Jammu region an institutional study

Background Chest trauma is a commonly encountered surgical emergency, constitutes about 10% of the total trauma, however 25% of fatalities are because of chest trauma. The aims of this study is to evaluate and document the causes modes of presentation, dignosis and modalities of treatment for chest trauma. Patient and Methods Prospetive study was done at Govt. Medical College (GMC) Jammu for a period of one year on cases of chest trauma. A total number of 2571 patients were admitted in Surgery department with poly trauma, 240 (9.3%) had chest injuries. Majority (78.7%) were males, with a mean age of 34.4 years. The mean hospital stay was 6.4 days and majority cases reached hospital with in 4 hours after injury. 81.7% cases had blunt trauma chest with Road Traffic Accidents (RTA) being the mode of injury and gunshot injury was the commonest among penetratting chest trauma victims. Clinical presentation and physical examination was sufficient for the dignosis, although some investigations, especially chest x-rays and thoracic Computed Tomographic (CT) scans were necessary in most of cases. Observations Only 16 (8.8%) patients required surgery and rest 91.2% managed on conservative line only. Rib fracture was the commonest injury (60%) followed by hemopneumothorax (51.7%), surgical emphysema (37.9), lung contusion (10.4%), flail chest (6.2%) etc. Associated injuries were seen in 117 (48.8%), with head injury the commonest one. Overall motality rate was 12%, which was higher in blunt chest trauma as compared to penetrating injuries. All these patients were managed by a protocol, which was standardized by postgraduate department of surgery of this institution. Coclusion The evaluation of thoracic injuries is important aspect of the total assessment of a severely injured patient, the incidence as high as 10%. Both diagnostic and therapeutic procedures go hand in hand most thoracic injuries can be treated adequately by intercostal tube drainage. Operative intervention has been found necessary in 6.75 of cases only     

Percutaneous tracheostomy: one center's experience with a new modality

BACKGROUND: A retrospective review of our experience with percutaneous tracheostomy was performed to determine our complication rate and pattern of use since this modality was introduced at our institution. METHODS: A retrospective chart review captured all patients in whom tracheostomy was performed or supervised by a trauma/critical care faculty member. Dates of hospital admission, ICU admission, intubation, discontinuation of mechanical ventilation, type and location of procedure, procedural complications, Injury Severity Score, charges, and patient demographics were collected. Percutaneous tracheostomy (PT) and open tracheostomy (OT) experiences were compared. RESULTS: Three hundred sixty-eight tracheostomies were performed (190 OT and 178 PT). The average time to tracheostomy (TTT) for PT patients decreased from 12.7 to 7.4 days. The average TTT for OT patients remained stable at 14.0 days. The complication rate was 3.5%, with 4 complications (1.5%) associated with OT and 9 complications (5.1%) associated with PT. All complications in the PT group occurred before using a single dilator system. The 9 complications in the PT group occurred among 5 surgeons, all before their 11th attempt. PT saves 444 dollars in charges per procedure. CONCLUSION: OT continues to be a safe method of performing tracheostomies. PT has a steep learning curve but can be mastered quickly. Benefits include a shorter time to tracheostomy, elimination of patient transport, and saving in charges. Initial PT attempts should be supervised by an experienced surgeon.

Routine chest X-ray after percutaneous tracheostomy is unnecessary

Percutaneous tracheostomy (PT) is an increasingly common procedure in the management of critically ill patients. Current practice for both open and percutaneous tracheostomies is a post-procedure chest X-ray to rule out potentially life-threatening complications such as a pneumothorax or tube malposition. Our study evaluated the utility of chest X-ray after PT. A retrospective chart review was conducted for patients undergoing PT at Kern Medical Center between January 1999 and December 2003. Charts were reviewed for age, sex, and clinical outcome as well as the radiologist's interpretation of the postprocedure chest X-ray. A total of 73 procedures were completed in 47 men and 26 women. The majority of the tracheostomies were in trauma patients who needed prolonged ventilatory support. There were no complications identified on postprocedure chest X-ray. A single patient was converted to an open procedure secondary to bleeding. We conclude that routine chest X-ray after PT is unnecessary.     

Early and late outcome of bedside percutaneous tracheostomy in the intensive care unit

To simplify long-term airway management in critically ill patients the feasibility of performing percutaneous tracheostomy (PT) in the intensive care unit (ICU) was investigated from August of 1997 to March of 2000. Bedside PT was considered for patients with positive end-expiratory pressure <10 cm H20, no previous tracheostomy, no anatomic distortion of the tracheal region, and no other indication to go to the operating room. Indication for tracheostomy, duration of endotracheal intubation, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, morbidity, and mortality were determined. Patients were prospectively followed until decannulation or for a minimum of 3 months. PT was performed in the ICU in 71 patients. Indications for PT were: acute respiratory failure (41), airway protection (26), and maxillofacial trauma (four). Mean duration of intubation before PT was 14 days (range 5-35 days). Average APACHE II score was 14 (range 3-28). Morbidity from PT included: early (two) and late (one) bleeding from the tracheostomy, early cuff leak (one), and self-decannulation (one). Sixteen patients died of causes unrelated to PT. Forty-five patients were decannulated after an average of 57 days (range 9-170 days); two noted a minor voice change. PT can be performed in the ICU with minimal morbidity eliminating the need for an operating room, the risks of patient transport, and the costs associated with each.

Acute tracheal trauma in sheep caused by percutaneous tracheostomy

The aim of our study was to compare dilation forceps tracheostomy and sequential dilator tracheostomy in anaesthetized live adult sheep with respect to the characteristics of the stoma formed and the associated injury. We performed percutaneous tracheostomy on adult sheep randomly allocated to receive either dilation forceps or sequential dilators. Sheep were sacrificed immediately after insertion of the percutaneous tracheostomy and the tracheas dissected. Specimens were examined for site, shape and size of stoma, mucosal lacerations, and posterior wall trauma. Ten sheep had dilation forceps tracheostomy and ten had sequential dilator tracheostomy. All of the specimens were found to have cephalo-caudal mucosal tears, usually crossing tracheal rings. The dilation forceps technique was found to have a larger stoma (28.8 mm vs 24.0 mm, P=0.023). The incidence of posterior needle trauma and mucosal lacerations were common (35% and 50% respectively), but they were not statistically different between the two groups. The role of the mucosal tears in the development of tracheal stenosis is reviewed in the discussion.     

Percutaneous dilatational tracheostomy versus conventional surgical tracheostomy

Background : As no clinical randomised studies have previously been performed comparing complications with the Ciaglia Percutaneous Dilatational Tracheostomy Introducer Set (PDT) and conventional surgical tracheostomy (TR), we designed a study with the aim of comparing the efficacy and safety of the two techniques.
Methods : Sixty patients selected for elective tracheostomy were randomised for either PDT (30 patients) or TR (30 patients). All patients had general anaesthesia and were ventilated with 100% oxygen. Furthermore, lidocaine with epinephrine 1% (3–5 ml) was used for local analgesia and to minimise bleeding during the procedure.
Results : The median time for insertion of the tracheostomy tube was 11.5 min (range 7–24 min) in the PDT group and 15 min (range 5–47 min) in the TR group ( P <0.01). Complications during the procedure were cuff puncture of the endotracheal tube in 5 cases in the PDT group. Minor bleeding was encountered in 6 cases in the PDT group as opposed to 24 cases in the TR group ( P <0.01), major bleeding in none versus 2 cases, respectively. In 8 cases in the PDT group, increased resistance to insertion of the tracheostomy tube was met by further dilatation. During the post-tracheostomy period, complications occurred with minor bleeding in 2 cases in the PDT group as opposed to 9 cases in the TR group ( P <0.05), and major bleeding was encountered in 1 case in each group. Minor infections were encountered in 3 cases in the PDT group as opposed to 11 cases in the TR group ( P <0.01). Major infection was encountered in none versus 8 cases, respectively ( P <0.01).
Conclusion : Our results indicate that the percutaneous dilatational tracheostomy technique performed with the Ciaglia Introducer Set is effective, safe and superior to conventional surgical tracheostomy as immediate complications as well as complications with the tracheostomy tube in situ are fewer and of less severity.     

Thoracotomy for blunt trauma: traditional indications may not apply

The indications for performing as urgent thoractomy after trauma are based on the criteria used for penetrating injuries. However, few data are available on the use of these indications for patients with blunt injuries. In a retrospective study (June 1996 to July 2001), we compared the indications of urgent thoracotomy after blunt injury and penetrating injury in patients who underwent thoracotomy within 24 hours of hospital admission at our institution. Patients with blunt aortic injuries or emergency department thoracotomies were excluded from evaluation. Fifty-nine patients were identified (37 penetrating injuries, 22 blunt injuries). Blunt trauma victims had a higher mortality rate than penetrating trauma victims (73% vs. 22%). Chest tube output was the indication for nontherapuetic thoracotomy in 5 patients with blunt injuries whereas this occurred in only 1 penetrating injury victim (P = 0.04). All 5 blunt injury patients underwent a prior procedure and were coagulopathic when thoracotomy was performed. In conclusion, thoracotomy following blunt trauma is associated with a high rate of mortality. The rate of nontherapeutic exploration is increased when chest tube output is the indication for thoracotomy after blunt trauma. Since the majority of such patients have multicavitary injuries that require prior operation and are commonly coagulopathic, caution should be exercised when deciding whether to proceed with thoracotomy based solely on chest tube output.     

The 1991 Fraser Gurd Lecture: evolution of airway control in the management of injured patients.

The evolution of methods for airway control has been an important factor in improving overall trauma care. Many important advances have been made in technique, tubes, and timing. Current methods of airway control are listed in Table 2 and are categorized as emergency or elective. It is always assumed that basic life support techniques will be in place before this hierarchic scheme for airway control is used. Unfortunately, hypoxemia continues to be a factor in preventable trauma deaths. There is much to be done in the future to further improve airway management in injured patients. There is an immediate need to assess methods of airway control in the pre-hospital phase using a randomized clinical trial. The ideal tube for cricothyroidotomy, tracheostomy, or endotracheal intubation remains to be designed. There is a need for further multicenter trials on the timing of tracheostomy in the critical care unit. The role of differential ventilators in the management of unilateral pulmonary parenchymal injury requires clinical validation. Intravascular membrane oxygenators have been proposed in advanced pulmonary insufficiency in a ventilated patient. Thus, while many important strides have been made in airway management following trauma, there remain great challenges in addressing the persistent problem of systemic hypoxemia after multiple injuries.     

Percutaneous tracheostomy in a patient with mandibulo-maxillary interfixation with modified approach for bronchoscopic guidance--case report

Percutaneous tracheostomy has replaced the surgical approach in many intensive care unit patients. In this case report, we present the use of percutaneous tracheostomy on a patient with mandibulo-maxillary interfixation. A 19-year-old male with severe maxillofacial injuries underwent mandibulo-maxillary interfixation. Percutaneous tracheostomy was planned. Because of the mandibulo-maxillary interfixation, however, neither direct laryngoscopy nor the fiberoptic bronchoscopy through the existing preformed nasal endotracheal tube could be utilized. A modified approach utilizing the fiberoptic bronchoscopy to safely withdraw the endotracheal tube was used. The bronchoscope was introduced from the other nostril and used to inspect the withdrawal of the ETT from outside. Our case demonstrates the feasibility of percutaneous tracheostomy in the setting of mandibulo-maxillary interfixation. To our knowledge this is the first report of percutaneous tracheostomy in this indication.     

Bedside percutanous forceps dilatational tracheostomy

ICU patients, mainly those who need prolonged ventilatory support, may require tracheostomy, which once was done in the operating room, nowadays is performed in the ICU, as percutaneous dilatational tracheostomy (PDT). Forty two patients 18-72 yrs of age (mean 44 yrs), with varying indications for tracheostomy, had undergone PDT in the ICU under the standard protocol for this procedure. The mean time for completion of the procedure was 10 min. Advantages and complications are reviewed. The difficulties encountered were mainly the anatomical landmarks (10%), difficulties in dilatation (5%) and peristomal oozing (1%). It is concluded that percutaneous dilatational tracheostomy is an easy, cost effective, practical when done at bedside in the ICU, and spares transferring the patient to the operating theater.     

A Population-Based Study of Pancreatic Trauma in Scotland

Introduction The aim of this population-based study was to assess the incidence, mechanisms, management and outcome of patients who sustained pancreatic trauma in Scotland over the period 1992–2002. Methods The Scottish Trauma Audit Group database was searched for details of any patient with pancreatic trauma. Results About 111 of 52,676 patients (0.21%) were identified as having sustained pancreatic trauma. The male-to-female ratio was 3:1, with a median age of 32 years. Blunt trauma accounted for 66% of injuries. Road traffic accidents were the most common mechanism of injury (44%), followed by assaults (35%). Thirty-four patients (31%) were haemodynamically unstable on arrival at hospital. Pancreatic trauma was associated with injuries to the chest (56%), head (30%) and extremities (30%); 73% of patients had other intra-abdominal injuries. Of those who left the emergency department alive, at least 77% required a laparotomy. The mortality rate (46%) was directly proportional to the number of injuries sustained (P < 0.05) and was higher in patients with increasing age (P < 0.05), haemodynamic instability (P < 0.05) and blunt trauma (P < 0.05). Conclusions Pancreatic trauma is rare in Scotland but is associated with significant mortality. Outcome was worse in patients with advanced age, haemodynamic instability, blunt trauma and multiple injuries. All work done in Edinburgh, Scotland, UK.
