Early complications of tracheostomy performed in the operating room

[Preliminary results of percutaneous tracheotomies]

OBJECTIVES

Percutaneous tracheotomy (PT) is an alternative to surgical tracheotomy (ST). We describe our procedure and discuss the current status of PT through a retrospective study of our first 30 cases.

MATERIAL AND METHODS

Thirty patients had a PT between October 2006 and March 2008 in the intensive care units of Caen University Hospital (France). Twenty-eight were done with the Ciaglia Blue Rhino (CBR) and two with the Percutwist. Each PT was endoscopically guided. We retrospectively collected preoperative data and most of the intraoperative as well as early postoperative complications.

RESULTS

No death was reported with the PT application. Twenty-two (73.3%) PTs had neither preoperative nor early postoperative complications. Eight complications were observed, half preoperative and half early postoperative. The most frequent complication was minor bleeding in three cases (10%), the most important one was the intraoperative appearance of a tracheoesophageal fistula with the CBR.

DISCUSSION

The principal advantages of PT are safety attributable to simultaneous endoscopic guidance as well as shorter operative time and lower cost in comparison with the ST technique.

CONCLUSION

PT is a safe and valid alternative procedure to ST. Initially performed by intensivists, it should be part of the ENT/head and neck surgeon's repertory as the upper airway specialist.

Tracheostomy: how and when should it be done in cardiovascular surgery ICU?

BACKGROUND

The aim of this study was to assess the effect of timing and techniques of tracheostomy on mortality and morbidity in cardiovascular surgery patients.

METHODS

Between January 2000 and October 2007, a total of 19,559 cardiac and vascular operations were performed in our hospital, and 205 of these patients (1.04%) who underwent a tracheostomy procedure were included in this retrospective study.

RESULTS

Surgical tracheostomy (ST) was employed in 134 (65.4%) and percutaneous tracheostomy (PT) in 71 (34.6%) of the cases. There were 17 complications related to all tracheostomy procedures in 15 (7.3%) patients. Bleeding, requiring surgical intervention, occurred in five (3.7%) ST patients and in one (1.4%) PT patient. Cardiac arrest related to the procedure occurred in two (1.5%) ST patients. Pneumothorax occurred in three (2.2%) ST patients and in one (1.4%) PT patient, subcutaneous emphysema in three (2.2%) ST patients and in one (1.4%) PT patient, and tracheoesophageal fistula in one (0.7%) ST patient (p>0.05). The postoperative infection rate was significantly lower, and cooperation of the patients, postoperative patient mobilization, and oral feeding rates were higher in the early tracheostomy group. The multifactorial mortality rates of early (<seven days) and late tracheostomies were 71.4% and 88.1%, respectively (p=0.037).

CONCLUSIONS

We believe that both techniques can be performed safely in the ICUs. Although the need of tracheostomy is one of the foremost causes of mortality and morbidity in cardiovascular surgery patients, an early application of the procedure may have favorable effects on the expected mortality and overall infection rates of the critically ill patients.

Traqueostomia na UTI: vale a pena realizá-la?

OBJETIVO: Analisar a viabilidade, as complicações e a mortalidade da traqueostomia realizada em ambiente de unidade de terapia intensiva (UTI). MÉTODOS: Análise retrospectiva dos prontuários médicos dos 73 pacientes que foram submetidos à traqueostomia nos leitos das UTIs do Hospital São Paulo da Universidade Federal de São Paulo no período de janeiro a novembro de 2003. Os procedimentos foram realizados sempre por um residente de cirurgia, sob a orientação de um cirurgião torácico, utilizando a técnica aberta sistematizada no serviço. RESULTADOS: A idade média dos pacientes foi de 55,2 anos, sendo que 47 eram do sexo masculino (64,4%) e 26 eram do sexo feminino (35,6%). A indicação mais freqüente foi a intubação orotraqueal prolongada (76,7%). Não houve mortalidade relacionada ao procedimento, e em todos os pacientes o procedimento pôde ser realizado na UTI. As complicações imediatas ocorreram em 2 pacientes (2,7%), nos quais houve sangramento local aumentado que cessou com compressão local. A complicação tardia foi a infecção ao redor da ferida operatória, a qual ocorreu em 2 pacientes (2,7%) e foi tratada com curativos locais, sem maiores repercussões clínicas. CONCLUSÕES: Com base nos resultados de nossa análise, os quais são comparáveis aos resultados sobre traqueostomias realizadas no centro cirúrgico encontrados na literatura, concluímos que a traqueostomia na UTI é viável e apresenta baixo índice de complicações, mesmo quando realizada em pacientes graves por cirurgiões em treinamento. Portanto, a nosso ver, é possível afirmar que vale a pena realizar a traqueostomia na UTI.

Endoscopic percutaneous dilatational tracheotomy: a prospective evaluation of 500 consecutive cases

OBJECTIVES/HYPOTHESIS

An evaluation of 500 adult, intubated, intensive care unit patients undergoing endoscopic percutaneous tracheotomy using the multiple and single dilator techniques was conducted to assess the feasibility and safety of the procedure as it compares with surgical tracheotomy. Endoscopy was used in all cases and evaluated as an added safety measure in reducing complications.

STUDY DESIGN

A prospective evaluation of endoscopic percutaneous dilatational tracheotomy in 500 consecutive adult, intubated intensive care unit patients.

METHODS

Between 1990 and 2003, endoscopically guided percutaneous dilatational tracheotomy (PDT) was performed in 500 consecutive adult, intubated patients in the intensive care units (ICU) of three tertiary care adult hospitals. The first 191 patients underwent PDT using the Ciaglia Percutaneous Tracheostomy Introducer Kit (Cook Critical Care Inc., Bloomington, Indiana) and in the remaining 309 patients the Ciaglia Blue Rhino Single Dilator Kit (Cook Critical Care Inc., Bloomington, Indiana) was used. The procedure was contraindicated in the following situations: 1) children, 2) unprotected airway, 3) emergencies, 4) presence of a midline neck mass, 5) inability to palpate the cricoid cartilage, and 6) uncorrectable coagulopathy. The following parameters were recorded preoperatively: age, sex, diagnosis, American Society of Anesthesia (ASA) class, body mass index (BMI), and number of days intubated. Recorded hematologic parameters included hemoglobin (Hgb), platelets, prothrombin time (PT), partial thromboplastin time (PTT), and the international normalized ratio (INR) since it became available in 1998. All patients were ventilated on 100% oxygen and vital signs were continuously monitored. Tracheotomy was carried out under continuous endoscopic guidance using a series of graduated dilators in the first 191 cases, and a single, tapered dilator in the remaining 309 patients. The preoperative data on each patient, along with the type of dilator used, the size of the tube, the intraoperative and postoperative complications, and blood loss information were recorded prospectively and maintained in a computer spreadsheet. Univariate analyses were used in each group separately for each type of dilator to assess the risks of a complication within subgroups defined by each parameter/characteristic, and the statistical significance assessed with a chi test, or Fisher exact test.

RESULTS

The total complication rate was 9.2% (13.6% in the multiple dilator group, and 6.5% in the single dilator group), with more than half of these considered minor. Overall, the two most common complications were oxygen desaturation in 14 cases and bleeding in 12 cases. The absence of serious complications such as pneumothorax and pneumomediastinum are attributable to the use of bronchoscopy. There was no significant association between the rate of complications and age, gender, ASA, weeks intubated, tracheostomy tube size, Hgb levels, platelets, PT, PTT, or INR. There was a statistically significant relationship between experience and the likelihood of complications in the multiple dilator group (P < .0001), with a higher rate of complications in the first 30 patients (40%) compared with 8.7% in the remaining 161 patients. This relationship did not exist for the first 30 patients in the single dilator group. Patients with a BMI of 30 or higher experienced a significantly greater (P < .05) number of complications (15%), compared with an 8% complication rate in patients with a BMI of less than 30. This risk was even more significant for patients with a BMI of 30 or greater who were also in ASA class 4 (11/56 or 20%) (P < .02).

CONCLUSIONS

Endoscopic PDT is associated with a low complication rate and is at least as safe as surgical tracheotomy in the ICU setting. Bronchoscopy significantly decreases the incidence of complications and should be used routinely. While embraced by critical care physicians, endoscopic PDT has been infrequently performed by otolaryngologists. As the airway experts, otolaryngologists are in the best position to learn and teach the procedure as it should be done.

Tracheotomy: timing and techniques

PURPOSE OF REVIEW

Until the past 40 years, the timing of tracheotomy was of little concern. It was an emergency procedure developed for the relief of airway obstruction. Following the development of positive pressure ventilation, tracheotomy became an elective procedure. Today, the optimal time for tracheotomy is a subject of dispute and continued investigation. As this operation has become one of the most commonly performed procedures in the intensive care unit, nonoperative dilational methods have gained acceptability. The purpose of this review is to analyze the recent literature and draw insight into the timing and technique of the current state of tracheotomy.

RECENT FINDINGS

Individualized assessment of patients should guide the timing of tracheotomy, with a preference toward early tracheotomy. Percutaneous dilational tracheotomy (PDT) can be performed with equivalent safety to open tracheotomy. Bedside open tracheotomy negates the cost-saving benefits of PDT. Endoscopic guidance in PDT decreases complications with needle placement and posterior tracheal wall injury. Major complications of PDT usually are associated with displacement of the tracheotomy tube.

SUMMARY

Tracheotomy indications have remained unchanged, but the timing of the procedure has advanced to individualized assessment with a predilection for earlier tracheotomy. The traditional operative technique is a much safer procedure today. Percutaneous dilational tracheotomy has become an acceptable alternative with proper patient selection. A multidisciplinary team with a surgeon provides the best care for the patient undergoing percutaneous tracheotomy.
