Percutaneous tracheostomy after trauma and critical illness.

A method of percutaneous tracheostomy (PT) using a tracheostome, which permits insertion of a full-sized cuffed tracheostomy tube, was evaluated in 61 critically ill or injured patients (89% had trauma). Of the 54 trauma patients, 65% had brain injuries, 14% had injuries to the cervical spinal cord, 33% had face or jaw injuries, and 15% had lung injuries. The indications for PT were coma (46%), acute airway obstruction (5%), face or jaw injury (20%), pneumonitis (39%), adult respiratory distress syndrome (12%), and sepsis (21%). Tracheostomy was done in 51% of all cases specifically for managing pulmonary secretions, in 37% for prolonged intubation, and in 25% for neurologic lesions. The tracheostomy was done as an emergency in 5%, as urgent in 28%, and electively in 77%. Percutaneous tracheostomy was successful in 90% of the cases, and in 8% it was converted to a surgical tracheostomy after an initial percutaneous attempt. In 46% it was performed at the bedside, in 46% in the operating room, and in 7% in the emergency suite. A full-sized tracheostomy tube (#6 to #8) was used in all cases and was considered optimal or larger than needed in 87% of cases. With three exceptions the complications of PT were minor, but 30% of the patients died of their primary disease. In one case death occurred because of bronchospasm and cardiac arrest during the PT, but appeared to be independent of the type of tracheostomy. Healing after in-hospital removal (37%) was excellent in 95% of cases and 97% of physicians indicated that they would use the device again.     

Tracheostomy in burns patients revisited

Objective

The use of tracheostomy in burns patients has been controversial. A retrospective study was conducted to assess the use, complications and outcome of tracheostomy in ventilated adult burns patients.

Methods

Data was collected retrospectively regarding the extent of injury in each patient, the indication for tracheostomy, and outcome in terms of length of stay, days of mechanical ventilation, airway and pulmonary complications and survival. Patients were followed until discharge from the unit or death.

Results

Comparing patients who received tracheostomy to those who had translaryngeal intubation showed similar age distribution and no significant difference in the total burn surface area (TBSA). The use of tracheostomy was significantly higher in patients with TBSA >60%. Inhalation injury was significantly higher and mean probability of survival (ABSI), significantly lower in patients receiving tracheostomy. Duration of mechanical ventilation, length of stay in HDU/ITU and the incidence of pulmonary sepsis were significantly higher in tracheostomy group patients. However, there was no significant difference in mortality between the two groups.

Conclusion

Burn survivors with TBSA >60% are more likely to undergo repeated surgery and have burns to the head and neck region, therefore increasing the requirement for tracheostomy. Tracheostomy is a safe procedure with minimal perioperative complications. Late complications in this patient group may be related to duration of intubation and mechanical ventilation and the presence of an airway burn.Tracheostomy was associated with a higher prevalence of chest infection. We suspect that the cause of this is multifactorial, possibly due to a higher incidence of inhalation injury, greater burn size and prolonged mechanical ventilation in this group.     

The impact of inhalation injury in patients with small and moderate burns

BackgroundInhalation injury is an independent risk factor of mortality in burn patients. The burn index (BI), which includes burn depth and size, also plays a role in predicting mortality. We aimed to establish a relationship between survival rate, inhalation injury, and BI.MethodsFrom 1997 to 2010, 21,791 burn patients from 44 hospitals were retrospectively reviewed. Kaplan–Meier and log-rank assessments were used for survival curve analysis. Chi-square, Fishers-exact test and odds ratio evaluations were used to assess the relationship between mortality rate, inhalation injury, BI. Two population proportion Z test was used to analyze the causes of death and morbidity. The significance level was set at 0.01.ResultsThe overall mortality rate was 2.1%. Inhalation injuries were found in 7.9% of the patients. The mortality rate of inhalation and non-inhalation injury group was 17.9% and 0.7%, respectively. The survival rate of the inhalation injury group was significantly lower than that of the non-inhalation injury group at BI 0–50. The patients with both inhalation injury and BI less than 50 had significant higher rate to die of pneumonia, respiratory failure, sepsis and wound infection. There was no significant difference when BI was larger than 50.ConclusionsInhalation injuries significantly reduced the survival rate, especially when the BI was less than 50. The possibility of pulmonary dysfunction and complications arising from inhalation injury should be considered even in patients who have small cutaneous burns associated with inhalation injuries.     

Tracheostomy in cardiosurgical patients: surgical tracheostomy versus ciaglia and fantoni methods.

BACKGROUND: Patients requiring prolonged mechanical ventilation are not uncommon in a cardiosurgical intensive care unit. Elective tracheostomy is considered the airway treatment of choice in these patients. METHODS: To evaluate different techniques for tracheostomy, we prospectively investigated 120 patients who had conventional open (n = 40), minimally invasive percutaneous dilatational (n = 40), or translaryngeal (n = 40) tracheostomy techniques. The main areas of investigation included oxygenation index (partial pressure of arterial oxygen divided by fraction of inspired oxygen), complications, infection, and cost. RESULTS: The oxygenation index decreased in almost every patient, regardless of the technique used, but the extent of decrease was significantly lower in both minimally invasive techniques compared with the conventional method. Overall complication rate was 12.5% both in open tracheostomy and in percutaneous dilatational tracheostomy, whereas no complications occurred in translaryngeal tracheostomy procedures. Bacterial contamination of the tracheostomy site was found in 35% of the open tracheostomies, whereas no infection was seen in percutaneous dilatational or translaryngeal tracheostomies. In terms of costs, PDT ($506) and TLT ($362) were both much cheaper than open tracheostomy ($699). CONCLUSIONS: Percutaneous dilatational and translaryngeal tracheostomies are safe and cost-effective procedures that can be done easily at the patient's bedside and thus are attractive alternatives to conventional surgical tracheostomy in long-term airway access in a cardiosurgical intensive care unit.     

Percutaneous or surgical trachetomy. Prospective, randomized comparison of the incidence of early and late complications]

BACKGROUND: To compare early and late complications after either conventional surgical or percutaneous dilatational tracheostomy. DESIGN: Prospective, randomized study. SETTING: General intensive care unit and neuro-surgical intensive care unit in a university hospital. PATIENTS: 50 consecutive patients, requiring tracheostomy for prolonged mechanical ventilation. INTERVENTIONS AND MEASUREMENTS: Patients were randomly allocated to receive either surgical (surgical group, n = 25) or percutaneous dilatational tracheostomy (percutaneous group, n = 25). Occurrence of perioperative complication were carefully evaluated during ICU stay. Late complications were evaluated with both physical and endoscopic examination at 1, 3 to 6 months after tracheostomy. RESULTS: All surgical and percutaneous tracheostomies were successfully completed and no deaths directly related to the tracheostomy procedures were reported. Completion of the procedure required 41 +/- 14 min in the surgical group and 14 +/- 6 min in the percutaneous one (p < 0.0001). The incidence of early perioperative complications was higher in the surgical group (36%) than in percutaneous one (12%), (p < 0.05). The endoscopic follow-up demonstrated one segmental malacia and one stenosis of the trachea in the percutaneous group only (p = n.s.). Skin repair was better after percutaneous tracheostomy than in the surgical group (p < 0.01). CONCLUSIONS: In experienced hands, percutaneous dilatational tracheostomy is as safe and effective as the conventional surgical tracheostomy. The percutaneous technique is less time-consuming and has a lower rate of early infectious complications with better cosmetic results than the surgical technique.

Bedside Percutaneous Tracheostomy: Clinical Comparison of Griggs and Fantoni Techniques

Elective tracheostomy is widely considered the preferred airway management of patients on long-term ventilation. In addition to open tracheostomy, a number of percutaneous procedures have been introduced during the last two decades, among them techniques according to Griggs (guidewire dilating forceps, or GWDF) and to Fantoni (translaryngeal tracheostomy, or TLT). The aim of the study was to evaluate these two techniques in terms of perioperative complications, risks, and benefits in critically ill patients. A series of 100 critically ill adult patients on long-term ventilation underwent elective percutaneous tracheostomy, either according to the Griggs (n= 50) or Fantoni (n= 50) technique. Tracheostomy was performed under general anesthesia at the patient's bedside. The mean (±SD) operating times were short, 9.2 ± 3.9 minutes (TLT) and 4.8 ± 3.7 minutes (GWDF) on average. Perioperative complications were noted in 4% of patients during either TLT or GWDF and included massive bleeding, mediastinal emphysema, posterior tracheal wall injury, and pretracheal placement of the tracheostomy tube. With regard to oxygenation, pre- and postoperative arterial oxygen tension divided by the fraction of inspired oxygen (PaO₂/FiO₂) ratios did not vary significantly, and no perioperative hypoxia was noted regardless of the technique used. We conclude that both TLT and GWDF represent attractive, safe alternatives to conventional tracheostomy or other percutaneous procedures if carefully performed by experienced physicians and under bronchoscopic control.     

Tracheotomy and tracheostomy techniques]

Tracheostomy has become the method of choice in managing patients requiring long-term mechanical ventilation. At present, there are several alternatives to conventional surgical tracheostomy such as percutaneous dilatational techniques according to Ciaglia, Frova, and Fantoni. The basic principle of these new techniques is percutaneous puncture of the trachea and subsequent dilatation of the puncture channel until the tracheal cannula can be inserted. The advantages are "bedside" performance in the intensive care unit and the use of minimal technical equipment. Nevertheless, dilatation tracheostomy is not always technically feasible and safe. Some significant complications and contraindications have been recognized recently. This should be taken into account when planning tracheostomy in long-term ventilated patients. Compared to conventional surgical tracheostomy, this new procedure retains its value and benefit only if these contraindications are carefully observed.     

Bedside Percutaneous Tracheostomy: Prospective Evaluation of a Modification of the Current Technique in 100 Patients

Percutaneous dilatational tracheostomy (PDT) is being increasingly used. Concerns have been raised as to its safety, especially when it is done at the bedside. A prospective evaluation was conducted of 100 consecutive, unselected critically ill patients with PDT. The mean intensive care unit (ICU) stay before PDT was 12 days. One surgeon performed PDT alone (5 cases) or assisted residents (95 cases) in all operations; 84 were performed at the ICU bedside. Only the first six patients were taken to the operating room solely for tracheostomy. A modified technique was used: (1) the endotracheal tube was left in place during sequential dilations; (2) dilators were inserted in a 60-degree cephalad orientation to the skin and directed caudally after penetration of the anterior tracheal wall; (3) a digit was inserted through the tracheal opening to guide withdrawal of the endotracheal tube to the level of the vocal cords; and (4) size 8 tracheostomy cannulas were inserted over 28F dilators. The average time from skin incision to insertion of the tracheostomy tube was 12 minutes (< 10 minutes, 41 patients; 10 to 15 minutes, 37 patients; > 15 minutes, 22 patients). Sixty-five percent had unfavorable anatomic conditions due to spinal precautions or diffuse neck edema. Postoperative complications occurred in four patients; surgical emphysema after tracheal lacerations in three, cannula dislodgment in one. All complications were successfully managed without an operation by tube exchange (n= 3) or observation (n= 1); there was no procedure-related mortality. Forty patients were available for long-term follow-up (6–18 months after tracheostomy) by telephone; one had persistent hoarseness without respiratory difficulty. We concluded that bedside PDT is safe and easy to teach when performed with a technique that ensures correct instrumentation.     

Inhalation injury in southwest China—The evolution of care

Aim

This study aims to review the changes in management of inhalation injury and the associated reduction in mortality over the past 2 decades.

Methods

The records of burn patients with inhalation injury hospitalised in our institute from 1986 to 2005 were retrospectively analysed. The incidence of inhalation injury and the associated mortality were analysed. Meanwhile, the relationship of inhalation injury with age, total burn area, tracheostomy intubation and mechanical ventilation were studied.

Results

The incidence of inhalation injury was 8.01% in the total 10 608 hospitalised burn patients during the 20 years surveyed. Inhalation injury was always associated with large-sized burn and was more common in adults. The incidence of tracheostomy and mechanical ventilation increased from 39.46 and 30.28% in the period from 1986 to 1995 to 70.12 and 39.74% from 1996 to 2005, respectively. The overall mortality of inhalation-injured burn patients was 15.88% compared with 0.82% of the non-inhalation group. The mortality of the burn patients with inhalation injury dropped from 25.29% during the first 10 years to 11.71% during the second decade (p < 0.01). Mortality secondary to inhalation injury as the lead cause decreased from 14.56 to 6.29% (p < 0.01).

Conclusion

The care of inhalation injury has made significant progress over the past 2 decades. The early diagnosis of inhalation injury, early airway control and pulmonary function assistance with mechanical ventilation contribute to the reduction of mortality.     

Effects of tracheostomies on infection and airway complications in pediatric burn patients

Considerable controversy exists as to whether tracheostomy is ever indicated in burn patients. New advents in the treatment of inhalation injury have improved survival, making the use of tracheostomy more usual. The purpose of this study was to analyze the outcome of tracheostomies, and the effect of time on complications. Patients requiring ventilatory support and tracheostomies were studied. Demographic data, hospital course, ventilatory parameters and complications were analyzed. Two hundred ninety patients required ventilation and 36 tracheostomy. Mean percentage of TBSA burned was 59%+/-4. Ninety percent of these patients presented with inhalation injury. Mortality in tracheostomy patients was 25 and 16% in all ventilated patients. Thirty-five percent of the patients developed late complications. Patients who had their airway converted to tracheostomy before day 10 postinjury had a significantly lower incidence of subglottic stenosis. and patients who required airway pressures over 50 cm H2O for more than 10 days had a significantly higher incidence of tracheomalacia. Pneumonia occurred at similar incidence in ventilated and tracheostomy patients. The mortality and late complications of pediatric burn patients with tracheostomy has decreased over the last decade. They do not present with higher incidence of pneumonia. Maintenance of airway pressures below 50 cm H2O and conversion of the artificial airway to tracheostomy before day 10 postinjury may be advisable in patients requiring long term ventilation to prevent late complications.     

Comparison of safety and cost of percutaneous versus surgical tracheostomy

Tracheostomy continues to be a standard procedure for the management of long-term ventilator-dependent patients. Traditionally the procedure has been performed by surgeons in the operating theater using an open technique. This routine practice has recently been challenged by the introduction of bedside percutaneous dilatational tracheostomy (PDT), which has been reported to be a cost-effective alternative. The purpose of this study is to evaluate and compare the safety, procedure time, cost, and utilization of percutaneous and surgical tracheostomies at a university hospital. A retrospective medical chart review was performed on all ventilator-dependent intensive care unit patients at the University of Virginia Medical Center undergoing tracheostomy during a 23-month period beginning December 26, 1996. Of the 213 patients identified for review, 74 and 139 patients received percutaneous and surgical tracheostomies, respectively. Of 74 percutaneous tracheostomies, 73 reviewed were performed by general surgeons, pulmonary physicians, or anesthesiologists in the intensive care unit; all open tracheostomies were performed by surgeons in the operating room, and one percutaneous procedure was performed in the operating room. Perioperative complications occurred in five of 74 patients (6.76%) during PDT; of these, three patients (4.1%) experienced major complications requiring emergent operative exploration of the neck. Three patients (2.2%) experienced perioperative complications during surgical tracheostomy. The mean procedure time was significantly shorter for the percutaneous procedure. Average charges per patient in an uncomplicated case including professional fees, inventory, bronchoscopy (if performed), and operating room charges were $1753.01 and $2604.00 for percutaneous and standard tracheostomies, respectively. These charges do not include the charges associated with surgical intervention after PDT complications. In contrast to previously published reports showing complications clustered during a physician's first 30 percutaneous cases, our study demonstrated no relationship between complication occurrence and physician experience. That is, no learning curve associated with performing PDT was evident. In addition there was no association seen between physician specialty and complication rate. PDT in the intensive care unit costs less than surgical tracheostomy performed in the operating room and can be performed in less time. Several other studies have recommended that bronchoscopy during PDT provides additional safety; however, in our series all three major complications took place during bronchoscopy-assisted percutaneous procedures. Our series suggests that PDT carries an appreciable risk of major complications. Careful patient selection and additional experience with the procedure may decrease complication rates to an acceptable level.     

An analysis of time and staff utilization for open versus percutaneous tracheostomies.

OBJECTIVE: We examined staff utilization and procedure length for percutaneous and open bedside tracheostomies in an intensive care setting. STUDY DESIGN: Prospective clinical outcomes study. METHODS: Intensive care unit (ICU) tracheostomy consults meeting criteria for bedside procedures were randomized to open or percutaneous procedures. The Cook percutaneous kit and a prepackaged tracheostomy tray were used. ICU nursing and respiratory therapy staff was present for all procedures. The total resident time, staff time, and procedure length were recorded. Twelve patients underwent percutaneous tracheostomy, and 12 received an open tracheostomy. RESULTS: An operating room nurse was present for 7 of the open procedures. Ancillary medical staff was present for 3 open tracheostomies: anesthesia for 2 and critical care for 1. Ancillary medical staff was present for 4 percutaneous tracheostomies: anesthesia staff for 1 and critical care for 3. The average resident presence, staff presence, and procedure length for open tracheostomies were 47, 30, and 12 minutes, respectively. For percutaneous tracheostomies, the times were 39, 29, and 12 minutes, respectively. One intraoperative complication occurred during a percutaneous procedure and 2 perioperative complications occurred: 1 in the open group and 1 in the percutaneous group. CONCLUSIONS: There was no significant difference in procedure length, resident time, or staff time between the 2 procedures. Ancillary staff was occasionally used but was not thought to be necessary for the majority of procedures. Both procedures can be safely and expediently performed in the ICU.     

A comparison of percutaneous and operative tracheostomies in intensive care patients

The aim of our study was to compare the complication rate of convenional surgical and percutaneous dilational tracheostomies performed under general anaesthesia in critically ill patients. Fifty-three consecutive patients whose lungs were mechanically ventilated and who required tracheostomy were randomised to undergo either conventional surgical tracheostomy (n = 28) in the operating room or percutaneous dilational tracheostomy (n = 25) in the intensive care unit under general anaesthesia. All of the procedures were successfully completed. No deaths were related to the performance of either tracheostomy technique. Three patients in each group required a dressing change for minor bleeding at the tracheostomy site. There was no major bleeding requiring blood transfusion. One patient in each group developed atelectasis detected on chest x-ray postoperatively. In the surgical tracheostomy group, there were two patients with cuff leaks, one with a stomal infection and one with a pneumothorax. None of these complications occurred after percutaneous, dilational tracheostomy. We conclude that the low incidence of complications in both groups indicates that percutaneous dilational tracheostomy can be performed as safely in the intensive care unit with general anaesthesia as surgical tracheostomy can be performed in the operating room.     

Clinical evaluation of the "T-Dagger": a new bedside percutaneous dilational tracheostomy device

A number of percutaneous dilational tracheostomy devices are now available for clinical use. Recently, a new percutaneous dilational tracheostomy device, the "T-Dagger" (Criticure Invasives, India), has been introduced for rapid bedside percutaneous tracheostomy. In a prospective preliminary study, we have performed percutaneous dilational tracheostomy (PDT) using the T-Dagger in 20 adult ventilated patients in order to evaluate the safety and efficacy of the new device. The T-Dagger facilitated bedside PDT in about 3 min with no untoward incidents. There was no significant bleeding, pneumothorax, pneumomediastinum, tracheal wall injuries or difficulty in ventilation in any of the patients. We conclude that the T-Dagger shows early promise in bedside percutaneous dilational tracheostomy. However, controlled studies are required in a larger patient population before it can be recommended for routine use.     

Percutaneous dilatational tracheostomy: still a surgical procedure.

Although percutaneous dilatational tracheostomy (PDT) has been shown to be a cost-effective bedside alternative to open tracheostomy (OT), prior reports of the complications of the procedure are contradictory. Reported complications range from minor events to fatal ones, in varying percentages. This prospective study was designed to identify the type and severity of complications accompanying the introduction of PDT to a tertiary medical center. Surgical and medical intensive care unit (ICU) patients requiring elective tracheostomy were identified as appropriate for PDT using approved institutional criteria. All procedures were performed at an ICU bedside in the presence of a surgeon privileged to perform OT. Demographic data, procedural information, and patient outcome (including minor and major complications, length of stay, and survival) were collected. PDT was performed in 96 ICU patients, with complete data available for 95 patients. PDT was performed in an average of 13.1+/-1.0 minutes. Twenty-three major and minor complications occurred, including two perioperative deaths, in 15 patients (15.8%). A total of 37 PDT patients (38.9%) died in the hospital, indicative of the severity of illness of patients requiring tracheostomy. Based on the experience to date, Cedars-Sinai Medical Center (Los Angeles, CA) continues to require a surgeon privileged to perform OT to participate in all PDT procedures.     

Endoscopic guided percutaneous tracheostomy: early results of a consecutive trial

Percutaneous tracheostomy is increasingly being used for patients needing prolonged ventilatory support. The purpose of this study was to assess the feasibility of widespread application of endoscopic guided percutaneous tracheostomy. Sixty-one consecutive ICU patients requiring prolonged mechanical ventilation underwent bedside endoscopic guided percutaneous tracheostomy. Using a modified Ciaglia technique, a #6-10 tracheostomy tube was introduced between the second and third tracheal rings. Bronchoscopic transillumination facilitated identification of the appropriate tracheostomy site, and verified satisfactory placement of dilators and tracheostomy tube. There was one procedure-related death due to arrhythmia. Procedure-related complications included (n = 7): bleeding (controlled with local pressure), two infections, two cuff tears, and two obstructions of the tracheal tube. The tracheostomy was eventually removed in 13 patients. Bronchoscopic evaluation of three patients at 4 months post-tracheostomy removal was normal and there has been no clinical evidence suggestive of tracheal stenosis in the remaining ten extubated patients. There was a 50% reduction in cost when compared to operative tracheostomy. Percutaneous tracheostomy is a simple, safe, cost-effective bedside procedure for critically ill ventilator-dependent patients. Endoscopic guidance appears to increase the safety of this procedure and may prevent complications of pneumothorax, subcutaneous emphysema, and paratracheal false passage previously reported with blinded percutaneous methods.     

Inhalation burn injury in children

With advances in burn care, many children are surviving severe burn injuries. Inhalation injury remains a predictor of morbidity and mortality in burn injury. Inhalation of smoke and toxic gases leads to pulmonary complications, including airway obstruction from bronchial casts, pulmonary edema, decreased pulmonary compliance, and ventilation–perfusion mismatch, as well as systemic toxicity from carbon monoxide poisoning and cyanide toxicity. The diagnosis of inhalation injury is suggested by the history and physical exam and can be confirmed by bronchoscopy. Management consists of supportive measures, pulmonary toilet, treatment of pulmonary infection and ventilatory support as needed. This review details the pathophysiology, diagnosis, and management options for inhalation injury.

Prospective randomized comparison of progressive dilational vs forceps dilational percutaneous tracheostomy

This trial prospectively compares two methods of percutaneous tracheostomy, both routinely used in ICU: the Ciaglia progressive dilational tracheostomy and the Griggs forceps dilational tracheostomy. One hundred patients were randomized using a single-blinded envelope method to receive progressive or forceps percutaneous tracheostomy performed at the bedside. Operative time, the occurrence of hypoxaemia or hypercapnia and complications were recorded. The progressive technique took longer than the forceps technique (median 7 (range 2-26) vs. 4 (1-16) minutes, P = 0.0005). Hypercapnia occurred in both groups but was more marked with the progressive technique (56 (16) vs. 49 (13) mmHg, P = 0.0082). Minor complications (minor bleeding, transient hypoxaemia, damage to posterior tracheal wall without emphysema) were also more frequent with the progressive technique (31 vs. 9 complications, P < 0.0001). Six major complications occurred with the progressive technique, none with the forceps technique (P = 0.0085): tension pneumothorax, posterior tracheal wall injury with subcutaneous emphysema, loss of airway with hypoxaemia, loss of stoma with impossible re-catheterization, and two conversions to another technique. In conclusion, progressive dilational tracheostomy took longer, caused more hypercapnia and more minor and major difficulties than forceps dilational tracheostomy.
