A survey of tracheostomy practice in a cardiothoracic intensive care unit

OBJECTIVE: The purpose of this study was to assess current practice of performing tracheostomies in critically ill cardiac surgical patients, to establish complication rates, and to identify areas of this clinical practice that could be improved. DESIGN: Retrospective observational study. SETTING: A cardiothoracic intensive care unit in a teaching hospital. PARTICIPANTS: The most recent series of 100 tracheostomies performed in patients admitted to the intensive care unit. INTERVENTIONS: Percutaneous or surgical tracheostomy for respiratory management. MEASUREMENTS AND MAIN RESULTS: A total of 95 patients had 1 tracheostomy performed. One patient had a tracheostomy performed twice, and 1 patient had a tracheostomy performed 3 times; these repetitions were caused by recurrent respiratory failure. The median time from tracheal intubation to tracheostomy was 5 days (range, 1-23 days; interquartile range, 4-8 days), and median period between insertion and decannulation was 20 days (range, 2-77 days; interquartile range, 12-25 days). The most common reason for insertion was an anticipated long weaning time (55%) followed by insertion after failed extubation (32%). The Ciaglia percutaneous dilational technique was used for 89% of tracheostomies, whereas surgical techniques were used for 8%. The most common complication was either complete or partial obstruction of the tracheostomy tube (24%) followed by infection of the tracheostomy site in 18% (17/94) and bleeding at the time of insertion (11%). CONCLUSION: The percutaneous dilational technique of tracheostomy was used predominantly in this unit. The median time from tracheal intubation to tracheostomy was 5 days. The most common complications were bleeding at the time of insertion, obstruction of the tracheostomy tube, and stomal infection.     

Tracheostomy: from insertion to decannulation

Tracheostomy is a common surgical procedure, and is increasingly performed in the intensive care unit (ICU) as opposed to the operating room. Procedural knowledge is essential and is therefore outlined in this review. We also review several high-quality studies comparing percutaneous dilational tracheostomy and open surgical tracheostomy. The percutaneous method has a comparable, if not superior, safety profile and lower cost compared with the open surgical approach; therefore the percutaneous method is increasingly chosen. Studies comparing early versus late tracheostomy suggest morbidity benefits that include less nosocomial pneumonia, shorter mechanical ventilation and shorter stay in the ICU. However, we discuss the questions that remain regarding the optimal timing of tracheostomy. We outline the potential acute and chronic complications of tracheostomy and their management, and we review the different tracheostomy tubes, their indications and when to remove them.     

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.     

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.     

Safety of percutaneous tracheostomy in obese critically ill patients: a prospective cohort study

Obesity has been described as a relative contraindication for percutaneous tracheostomy. The objective of our study was to examine the safety and complications of percutaneous tracheostomy in obese patients. We conducted a prospective cohort study of all consecutive patients who underwent percutaneous tracheostomy at a tertiary medical-surgical intensive care unit between May 2004 and October 2005. We compared percutaneous tracheostomy in obese patients (body mass index > or = 30 kg/m2) to non-obese patients. We documented the occurrence of the following complications: aborting the procedure, accidental extubation, conversion to surgical tracheostomy, paratracheal placement, the development of pneumothorax, major bleeding (requiring blood product transfusion or surgical intervention) or death. We also documented hypoxia, minor bleeding (requiring pressure dressing or suturing), subcutaneous emphysema and transient hypotension. During the study period, 227 percutaneous tracheostomies were performed. There were 50 percutaneous tracheostomies in the obese group and 177 in the non-obese group. In 45 obese patients, percutaneous tracheostomy was performed without bronchoscopic guidance. Major complications were significantly higher in obese patients (12% vs. 2%, P = 0.04), while the rate of minor complications was not significantly different between the two groups. There were no instances of death or pneumothorax, subcutaneous emphysema or need for surgical intervention during or in the postoperative period in either group. Our study suggests that percutaneous tracheostomy can be performed safely in the majority of obese patients.     

PercuTwist-Dilatationstracheotomie

BACKGROUND: Percutaneous dilational tracheostomy (PDT) is considered to be an accepted method in intensive care patients. In 2002 Frova and Quintel described a method of dilation that employed controlled rotation of the PercuTwist dilational device. The goal of the present study was to evaluate the new technique employed by an experienced team. PATIENTS AND METHODS: Prospective, observational clinical study in 54 intensive care patients who required PDT. All tracheostomies were accompanied by bronchoscopic control. Vital parameters and perioperative complications were registered. RESULTS: In all 54 consecutive PercuTwist tracheostomies no severe complications were noted. Accidental tracheal ring fracture was noted in 7 patients while bleeding that needed surgical care occurred in 1 patient. CONCLUSION: The PercuTwist tracheostomy is a safe procedure for intensive care patients. More prospective studies that would compare the PercuTwist tracheostomy with the other PDT methods are necessary.     

Bedside percutaneous tracheostomy experience with 72 critically ill patients

Tracheostomy is necessary in intensive care unit (ICU) patients requiring prolonged mechanical ventilation. As an alternative to the standard surgical method, percutaneous techniques are available. Seventy-two patients were electively selected for percutaneous tracheostomy (PCT) in a nine-bed combined medical-surgical intensive care unit. PCT was performed at bedside with the Portex Percutaneous Tracheostomy Kit that uses the Griggs technique. The procedure time and early complications were recorded. The procedure was successful in all patients. The average duration of placement was 7.4 min. There were no tracheostomy-related deaths. Major bleeding occurred in three patients and required surgical intervention. In one patient, minor bleeding occurred at the stoma site that resolved with applied pressure. Wound infections were treated with local antiseptics in two patients. These findings suggest that PCT is a simple, quick and safe procedure.     

Suprastomal tracheal stenosis after dilational and surgical tracheostomy in critically ill patients

We have previously reported cases of severe suprastomal stenosis after tracheostomy. In this observational study we investigated the occurrence of suprastomal stenosis as a late complication. Patients with persistent tracheostomy after intensive care underwent an endoscopic examination of tracheostoma, larynx and trachea. A percutaneous dilational tracheostomy was employed in 105 (71.9%) and surgical tracheostomy in 41 (28.1%) of the cases (n = 146). The incidence of severe suprastomal stenosis (grade II > 50% of the lumen) was 23.8% (25 of 105) after dilational tracheostomy and 7.3% (3 of 41) after surgical tracheostomy (p = 0.033). Age, gender, underlying disease, ventilation time, and swallowing ability were not significantly associated with the tracheal pathology. This study suggests that dilational tracheostomy is associated with an increased risk of severe suprastomal tracheal stenosis compared to the surgical technique.     

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 tracheostomy: a safe procedure in the morbidly obese

BACKGROUND: Percutaneous dilational tracheostomy (PDT) is becoming a widely accepted technique that has replaced open tracheostomy (OT) in many hospitals. One of the remaining relative contraindications is morbid obesity. There are no published case series of its use in this patient population. We reviewed our experience with PDT in the morbidly obese and compared it to OT in this patient population. Our hypothesis is that PDT and OT have a similar frequency of adverse events. STUDY DESIGN: We reviewed charts of all morbidly obese patients (body mass index [BMI]>or=35, calculated as kg/m2) undergoing either PDT or OT at our institution during a 58-month period. Variables examined included age, gender, BMI, diagnosis, bedside or operating room, and bronchoscopy-assisted. We recorded all procedural complications and all tracheostomy-related complications that occurred for 30 days postprocedure or death. Primary adverse end points were defined as procedures that started percutaneous and converted to open; any reoperation related to the initial tracheostomy; malpositioning of tracheostomy resulting in patient morbidity, loss of airway control, and bleeding requiring surgical intervention. Secondary adverse end points occurred when a tracheostomy tube was dislodged or malfunctioned, as in the case of a cuff leak, and any bleeding that occurred more than 24 hours after insertion. RESULTS: From January 1, 2000, until September 30, 2004, our institution performed 1,062 tracheostomies. One hundred forty-three patients had a BMI>or=35. Eighty-nine patients underwent PDT and 53 patients underwent OT. Sixty-seven of the PDTs were performed at the bedside and 22 were performed in the operating room. All OTs were performed in the operating room. Five (6.5%) primary end points were recorded for PDTs (4 conversions to open, 1 malpositioning). Three (6.5%) primary end points were reported for OTs (malpositioning resulting in hypoxia, bleeding requiring surgical intervention, aborted attempt at open). CONCLUSIONS: PDT is a safe procedure to perform on morbidly obese patients.     

Percutaneous dilational tracheostomy. Indications--techniques--complications

Tracheostomy is a generally accepted procedure that assures free access to the airways in long-term lung ventilation. Apart from surgical tracheostomy, percutaneous dilational tracheostomy (PDT) has been increasingly employed in intensive care units. Presently, five dilatation methods are available, all equally allowing the performance of a secure and low-risk, bedside tracheostomy in the intensive care unit. Exact knowledge of the anatomy of the neck region and of the entire procedure are preconditions for a safe intervention. Percutaneous procedures offer advantages over surgical tracheostomy in terms of complications. To minimize the risks, expertise in airway management during PDT and knowledge of the particularities of cannula replacement in dilational tracheostoma, are compulsory. Endoscopic control assures that the tracheostoma can be placed correctly and that possible complications can be recognised early. The incidence of a serious tracheal stenosis after PDT is low.

Cricoid Palpability as a Selection Criterion for Bedside Tracheostomy

OBJECTIVE: To prospectively evaluate the significance of cricoid cartilage palpability as a selection criterion for bedside tracheostomy and to prospectively compare a cohort of patients undergoing bedside tracheostomy with another cohort receiving operating room tracheostomy. STUDY DESIGN/SETTING: Prospective trial comparing 2 cohorts of patients receiving tracheostomies at a tertiary care center (university hospital). In all, 220 consecutive intubated patients selected for elective tracheostomy were enrolled. Of them, 134 patients had palpable cricoid cartilage and underwent open surgical tracheostomy at the bedside. The remaining 68 patients received open surgical tracheostomies in the operating room. Demographic data, patient anatomic features, and perioperative complications were prospectively recorded. There were no statistically significant differences in age, gender, reason for admission, indication for tracheostomy, Acute Physiology and Chronic Health Evaluation II score, number of days intubated, or time required to perform the procedure for those patients whose tracheostomies were performed in the operating room versus the intensive care unit. RESULTS: Patients with a palpable cricoid cartilage had a significantly reduced perioperative complication rate compared with those without a palpable cricoid cartilage (2% vs 22%, P < 0.001). Comparison of cervical girth, mental-to-sternum distance, and thyroid-notch-to-sternum distance showed no significant difference between the 2 groups and did not further define selection criteria. CONCLUSION: This investigation prospectively confirms the safety of bedside tracheostomy placement in properly selected patients. Complication incidences are defined for open surgical tracheostomy at the bedside and in the operating room. Palpability of the cricoid cartilage has significant value as a selection criterion for bedside tracheostomy. SIGNIFICANCE: These findings will aid in the development of protocols and pathways for surgical airway management in critically ill patients to maximize cost-effective, high-quality care.     

Percutaneous (Portex) tracheostomy: an audit of the Newcastle experience

The purpose of this study was to audit the results of percutaneous tracheostomies performed by ENT surgeons in Newcastle. During a 3-year period, 298 tracheostomies: 196 percutaneous and 102 open were studied. A complication rate for percutaneous tracheostomy was found to be 10% compared to 8% for open, this difference was not statistically significant chi 2 = 0.279, P = 0.598 (DF = 1). The indications for percutaneous tracheostomy were mainly limited to respiratory support for intensive care unit patients, whereas the majority of open tracheostomies were performed in the operating theatre. The results of this audit suggest that percutaneous tracheostomy is the method of choice for respiratory support in the intensive care unit and is as safe as the open technique.     

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.     

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.     

Use of the ProSeal Laryngeal Mask Airway to initiate ventilation during intensive care and subsequent percutaneous tracheostomy

The ProSeal Laryngeal Mask Airway is a supraglottic airway that aims to provide improved airway seal and separation of the gastrointestinal and respiratory tracts. We report two cases in which the ProSeal Laryngeal Mask Airway was used to initiate controlled ventilation in the intensive care unit and subsequently provide airway maintenance during percutaneous dilational tracheostomy. The first case involved a patient with a known difficult airway who had previously been impossible to intubate conventionally. In both cases, airway management and subsequent tracheostomy were performed without complication.     

Safety and complications of percutaneous tracheostomy in a cohort of 800 mixed ICU patients

Percutaneous tracheostomy is used primarily to assist weaning from mechanical ventilation in the intensive care unit. We report our experiences of 800 such procedures performed in the intensive care unit by a collaborative team (critical care and ENT specialists). Most procedures (85.6%) were performed by residents supervised by the intensive care unit staff. Complications occurred in 32 patients (4%). Intraprocedural complications occurred in 17 patients (2.1%), early postprocedural complications in six (0.75%), and late postprocedural complications in nine (1.1%). No deaths were directly related to percutaneous tracheostomy. The incidence of complications was greater in percutaneous tracheostomy performed by the residents during their initial five attempts compared to their later attempts (9.2% vs 2.6%, p < 0.05). The low incidence of complications indicates that bedside percutaneous tracheostomy can be performed safely as a routine procedure in daily care of intensive care unit patients.     

First line application of a modified dilatational tracheostomy in the intensive care

BACKGROUND: Despite the growing clinical use of the percutaneous dilatational tracheostomy data concerning their first line application are still lacking. METHODS: Retrospective analysis of the intra- and postinterventional morbidity of a modified dilatational tracheostomy in a surgical intensive care unit of a German university hospital over a 2-year period. RESULTS: A total of 107 elective dilatational tracheostomies were performed in 105 patients. There were no intraoperative complications. 2 accidental decannulations occurred in the postoperative period. One conventional tracheostomy had to be performed secondary. Stoma side bleeding or clinical relevant infection had not been observed. After definite decannulation wound closure was spontaneous in all patients. CONCLUSIONS: The first line application of the dilatational tracheostomy has a low morbidity.
