Percutaneous tracheostomy: comparison of Ciaglia and Griggs techniques

A clinical retrospective study of percutaneous dilatational tracheostomy without guide wire for critically ill patients

OBJECTIVE

This study aimed to introduce a novel tracheostomy method, the non-guide-wire percutaneous dilatational tracheostomy (NGPDT) technique, and evaluate its effectiveness for critically ill patients undergoing neurosurgery under special conditions.

METHODS

The clinical data of 48 critically ill patients who underwent NGPDT under special conditions with controlled steps were analyzed retrospectively. The patients' demographic, preoperative state of illness, and diagnosis data were collected. Moreover, their intraoperative and postoperative variables were accessed, e.g., operation times, bleeding, saturation of pulse oxygen (SPO₂), and early and late complications related to NGPDT.

RESULTS

The mean patient age was 47.7 ± 13.7 years. The mean GCS (Glasgow Coma Scale) was 8.1 ± 2.9, and the mean BMI (Body Mass Index) was 25.2 ± 5.6. There were 38 patients with an endotracheal tube. The mean duration of onset to NGPDT was 4.0 ± 1.3 days. The mean operation time was 4.2 ± 1.9 min. There were 41 patients with mild intraoperative bleeding, 5 with moderate bleeding, and 2 with severe bleeding as well as 46 with mild postoperative bleeding and 2 with moderate bleeding. Additionally, 41 patients required complete extubation after NGPDT. The mean duration of incision healing was 4.8 ± 3.1 days. There was 1 patient with a decrease of SPO₂ ≥ 10%. Three patients presented with a transient violent cough at the primary tracheostomy stage; however, no patients suffered from pneumothorax, subcutaneous emphysema, false passage, or surgery-related death during this procedure.

CONCLUSION

Overall, NGPDT with controlled steps is a fast, safe, and microinvasive procedure. It mildly stimulates the trachea with a low rate of complications.

Classification of laryngeal injury in patients with prolonged intubation and to determine the factors that cause the injury

OBJECTIVE

This study aims to evaluate injuries occurring in the larynx of patients intubated in intensive care units for a long time.

STUDY DESIGN

Prospective clinical study.

SETTING

Tertiary hospital.

SUBJECT AND METHODS

Between April 15, 2019, and November 15, 2019, 40 patients who were hospitalized in intensive care units had a tracheotomy procedure due to prolonged intubation, and laryngeal structures were evaluated by direct laryngoscopy. The laryngeal structures were evaluated in four groups as glottic-supraglottic region, arytenoid vocal process, interaritenoid region and subglottic region. Edema, granulation and ulceration findings in these four regions were recorded. The injuries to the laryngeal structures were classified as stages 0-3. As a result of the data obtained, the relationship between the degree of laryngeal lesions and the factors that may cause these lesions was investigated.

RESULTS

According to our classification, nine patients had stage 1, 16 patients had stage 2 and 15 patients had stage 3 laryngeal injury. There was no significant relationship between the stage of laryngeal injury and age, sex and diameter of the intubation tube. There was a statistically significant relationship between laryngeal injury and the day the tracheotomy was performed (p = 0.007).

CONCLUSION

In patients that had prolonged endotracheal intubation, injury to the laryngeal structures is inevitable. To minimize this occurrence, tracheotomy should be performed for intubations that extend for more than seven days. When performing the tracheotomy, the laryngeal structures should be evaluated, necessary precautions should be taken for the traumatic lesions that are difficult to heal, and treatment should be started.

Comparison of Ciaglia and Griggs Percutaneous Tracheostomy Techniques - A Biomechanical Animal Study

Background and aims

The two most common commercial percutaneous dilation tracheotomy (PDT) sets apply different techniques. Our aim was to investigate the biomechanical properties of these two techniques on an animal model, that simulate a human trachea.

Materials and methods

Biomechanical properties of the different steps of the Ciaglia Blue Rhino® and Griggs Portex® techniques were measured on 20 pig cadavers.

Results

We found that the use of the two different devices created equal sized openings in the trachea (p >0.05). The force needed to insert the Griggs forceps was 1.8 kg average compared to 2.51 kg using the Ciaglia dilator (p <0.00001). The calculated total energy expenditure in the Ciaglia Blue Rhino® kit was 1.46 times greater than the Griggs Portex® kit (p <0.0001). This was mainly due to the amount of energy required during the final dilator stage, which was 4 times more using the Ciaglia Blue Rhino® dilator than the Portex® Griggs-dilator forceps.

Conclusion

We conducted a series of biomechanical properties experiments on an animal model of PDT using two popular commercial kits – Griggs Portex® guidewire dilating forceps by Smiths Medical and Ciaglia Blue-Rhino® by Cook Medical. The Ciaglia technique required almost 50% more energy to perform a PDT (p <0.0001), mainly because of the force exerted during the final dilator insertion stage compared to the Griggs forceps. Further research is needed to examine if these properties are related to some of the PDT complications.

Percutaneous tracheostomy by Griggs technique under rigid bronchoscopic guidance is safe and feasible in children

OBJECTIVE

The aim of this study is to report prospective data of pediatric cases that underwent percutaneous tracheostomy (PT) to show that PT is a safe and feasible procedure in children even in small infants.

PATIENTS AND METHODS

PT was done in 51 consecutive patients. Demographic data, indications, complications and outcome were recorded prospectively. Initial 6 PT was done by Giaglia technique whereas the Griggs technique was used in the consecutive 45 patients.

RESULTS

Fifty-one patients with mean age of 38±54months (1month-17years) and, mean weight of 12.4±13kg underwent PT. The only major complication was perforation of esophagus (n=1, 2%) which was recognized early and immediately repaired by cervical approach. This complication occurred in the 6th case done with the Giaglia technique. After conversion to the Griggs technique no major complication was encountered in the consecutive 45 procedures. The mean period of follow up was 21±13.7months. Narrowing of the stoma site requiring simple dilation was developed in 3 (5.8%) patients.

CONCLUSION

PT is a safe and easy procedure and a less invasive alternative to surgical tracheostomy even in small infants. We strongly recommend PT done by Griggs technique in children. It is important that it should be done in an operating room setting and under rigid bronchoscopic guidance.

The role of cricothyrotomy, tracheostomy, and percutaneous tracheostomy in airway management

Cricothyrotomy, percutaneous dilation tracheostomy, and surgical tracheostomy are cost-effective and safe techniques employed in the management of critically ill patients requiring insertion of an artificial airway. These procedures have been well characterized and studied in the surgical, emergency medicine, and critical care literature. This article focuses on the role of each of these modalities in airway management, specifically comparing the data for each procedure in regard to procedural outcomes. The authors discuss the techniques available and the relevant background data regarding choice of each method and its integration into clinical practice.

Is routine chest X-ray after surgical and percutaneous tracheostomy necessary in adults: a systemic review of the current literature

BACKGROUND

For many years, routine post-tracheostomy chest X-ray has been the standard of care for patients in many countries. However, recent evidence suggests that this is unnecessary and cost-ineffective.

OBJECTIVE

To review the current literature and examine the role of routine post-tracheostomy chest X-ray in adult patients.

TYPE OF REVIEW

Systemic review.

SEARCH STRATEGY

Electronic databases (PubMed, EMBASE, Cochrane) were searched using the keywords 'chest X-ray/radiography/radiograph' and 'tracheostomy/tracheotomy' in various permutations. Search period ranged from 1960 to 2012. Inclusion criteria included systematic reviews, meta-analyses, randomised control trials, prospective and retrospective case series. Paediatric and non-English articles were excluded. Abstracts and subsequently full text articles were screened by two of the authors independently. References from obtained articles were also examined.

EVALUATION METHOD

Specific outcome measures were collated to evaluate the usefulness of post-tracheostomy chest X-ray: Chest X-ray detected (tracheostomy-related) complication rates Proportion of cases requiring significant intervention Potential predictors of complications

RESULTS

Routine post-tracheostomy chest X-ray is of a low yield, and its findings had limited impact on patient management. Complication detection rates for surgical and percutaneous tracheostomy are 2.2% and 3.2%, respectively. Only 0.7% and 1.8% of chest X-rays performed in surgical and percutaneous tracheostomy cases, respectively, required intervention. Certain groups of patients, however, are at higher risks of complications, and may benefit from post-tracheostomy chest X-ray. For surgical tracheostomy, these groups include those with post-operative signs and symptoms of complications or had emergent or 'difficult' tracheostomies. For percutaneous tracheostomy, high-risk patients include trauma cases (unspecified), patients with post-procedural signs and symptoms of complications, patients who have high ventilatory requirements, difficult tracheostomy cases or tracheostomy cases performed without bronchoscopic guidance.

CONCLUSION

The practice of routine post-tracheostomy chest X-ray is debatable owing to its low yield and minimal impact on clinical management. However, certain groups of patients appear to be at higher risks of post-tracheostomy complications; currently, there is insufficient evidence to conclude the absolute need for routine chest X-ray in these groups of patients, although it may be prudent to do so based on available evidence in the literature and logical clinical reasoning.

[Percutaneous tracheostomy through dilatation with the Ciaglia Blue Dolphin(®) method]

OBJECTIVE

To describe the perioperative and postoperative complications in critically ill patients requiring percutaneous tracheostomy using the Ciaglia Blue Dolphin(®) technique.

DESIGN

A prospective, observational, cohort study was carried out.

SCOPE

Two medical-surgical Intensive Care Units.

PATIENTS

Adult patients subjected to prolonged mechanical ventilation.

INTERVENTION

Percutaneous tracheostomy using Ciaglia Blue Dolphin(®) with an endoscopic guide.

VARIABLES

Demographic variables, intraoperative and postoperative complications, and Intensive Care Unit and ward mortality were recorded.

RESULTS

Seventy patients were included. Age: 68.6 ± 12 years (68.6% males). APACHE II score: 23.5±8.7. Duration of mechanical ventilation prior to percutaneous tracheostomy: 14.3 ± 5.5 days. Perioperative complications were recorded in 25 patients. In 23 of them the complications were mild: difficulty inserting the tracheostomy cannula (n=10), mild bleeding (n=7), partial atelectasis (n=3), cuff leak (n=2), and technical inability to complete the procedure (switch to Ciaglia Blue Rhino(®)) (n=1). Severe complications were recorded in 2 patients: severe bleeding that forced completion of the procedure via surgical tracheostomy (n=1), and false passage with desaturation (n=1). None of the complications proved life-threatening. Eleven complications occurred in the learning curve. As postoperative complications, mild peri-cannula bleeding was seen in 2 patients.

CONCLUSIONS

Percutaneous tracheostomy using the Ciaglia Blue Dolphin(®) technique with an endoscopic guide is a safe procedure. As with other procedures, the learning curve contributes to increase the incidence of complications. Potential benefits versus other percutaneous tracheostomy techniques should be explored by randomized trials.

Single dilator vs. guide wire dilating forceps tracheostomy: a meta-analysis of randomised trials

BACKGROUND

Single dilator technique (SDT) and guide wire dilating forceps (GWDF) are the two most commonly used techniques of percutaneous dilatational tracheostomy (PDT) in critically ill adult patients. We performed a meta-analysis of randomised, controlled trials comparing intraoperative, mid-term and late complications of these two techniques.

METHODS

Pertinent studies were searched in BioMedCentral, PubMed, Embase and the Cochrane Central Register of clinical trials. We selected all randomised studies comparing SDT and GWDF techniques in adult critically ill patients published in a peer-reviewed journal.

RESULTS

Among 1040 retrieved studies, five eligible studies randomising 363 patients (181 to GWDF, 182 to SDT) were identified. The incidence of the composite outcome difficult cannula insertion/difficult dilation or failure was higher with the GWDF technique (15.5% vs. 4.9 %, P = 0.02). Moreover, intraprocedural bleeding was more common in the GWDF group (19.3% vs. 7.6% in SDT group, P = 0.018). A trend towards an increased incidence of fracture of tracheal rings was noted in the SDT group (6.5% vs. 0.5% in the GWDF group, P = 0.13). No difference in mid-term or long-term complications was observed.

CONCLUSION

GWDF technique is associated with a higher incidence of intraprocedural bleeding and of technical difficulties in completing the procedure (difficult cannula insertions/difficult dilations or failures) compared with the SDT technique. No differences were identified in mid-term and long-term complications. Further studies comparing SDT and GWDF in the general population and in subgroups of high-risk patients (like obese or hypoxaemic patients) are warranted.

Percutaneous tracheostomy, a systematic review

BACKGROUND

Percutaneous dilatational tracheostomy (PDT) is a common procedure in intensive care units and the identification of the best technique is very important. We performed a systematic review and meta-analysis of randomized studies comparing different PDT techniques in critically ill adult patients to investigate if one technique is superior to the others with regard to major and minor intraprocedural complications.

METHODS

BioMedCentral and other database of clinical trials were searched for pertinent studies. Inclusion criterion was random allocation to at least two PDT techniques. Exclusion criteria were duplicate publications, nonadult studies, and absence of outcome data.

STUDY DESIGN

Population, clinical setting, and complications were extracted.

RESULTS

Data from 1130 patients in 13 randomized trials were analyzed. Multiple dilators, single-step dilatation, guide wire dilating forceps, rotational dilation, retrograde tracheostomy, and balloon dilation techniques were always performed in the intensive care unit. The different techniques and devices appeared largely equivalent, with the exception of retrograde tracheostomy, which was associated with more severe complications and more frequent need of conversion to other techniques when compared with guide wire dilating forceps and single-step dilatation techniques. Single-step dilatation technique was associated with fewer failures than rotational dilation, and fewer mild complications in comparison with balloon dilation and guide wire dilating forceps (all P < 0.05).

CONCLUSIONS

Among the six analyzed techniques, single-step dilatation technique appeared the most reliable in terms of safety and success rate. However, the number of available randomized trials was insufficient to confidently assess the best PDT technique.

Subglottic stenosis following percutaneous tracheostomy: a single centre report as a descriptive study

Tracheal stenosis is a potential complication of tracheostomy. The present study aimed to describe the epidemiologic profile of subglottic stenosis in a referral medical centre. During a 4-year period, all patients who had been admitted in an Intensive Care Unit of Imam Khomeini Hospital (affiliated to Tehran University of Medical Sciences) and had undergone percutaneous tracheostomy during 7-10 days after endotracheal intubation were enrolled in the study. After removing the tracheostomy tube, patients were evaluated regarding development of tracheal stenosis using fiberoptic bronchoscopy and multi-slice computed tomography scan. During the study period, percutaneous tracheostomy was performed in 140 patients with a mean age of 38 years. Overall 54 patients died due to the severity of the disorder during hospitalization. In the remaining 86 patients, 54 cases needed permanent or long-term mechanical ventilation and were excluded from the study. Twelve patients died during the first 3 months and 20 patients were left for final assessment. Multi-slice computed tomography scan imaging showed subglottic stenosis in 17 cases (85%). Of these, 9 patients (52%) had tracheal stenosis of < 50%. Tracheal stenosis of 25- 40% was found in 5 cases (25%). Patients in whom the tracheostomy tube had been removed in the first 3 weeks after tracheostomy did not present tracheal stenosis (n = 3, 15%). The present study revealed that subglottic stenosis is frequent in patients who have undergone percutaneous tracheostomy in the Intensive Care unit setting. However, the stenosis is generally mild and is not associated with serious and/ or life-threatening clinical manifestations.

Safety and practicability of percutaneous translaryngeal tracheotomy (Fantoni technique) in surgery of maxillofacial and oropharyngeal tumours--own results and review of the literature

BACKGROUND

The study examines the suitability of the Fantoni method of translaryngeal tracheotomy (TLT) for airway management after surgery due to oropharyngeal and maxillofacial tumours.

PATIENTS AND METHODS

During a 4-year period, 156 translaryngeal pull-through tracheotomies were performed in 145 patients. This method is the only puncture tracheotomy technique that involves a dilatation process from inside the trachea to the outside through the skin and differs from other established puncture methods regarding practicability and frequency of complications.

RESULTS

The mean puncture time (from puncture of the trachea to correct tube placement) was 10.1+/-4.8 min. With an oxygen supply of FiO(2)=1.0 the oxygen saturation prior to TLT was 98.4+/-1.29%, and the lowest median saturation value during the TLT procedure was 96.7+/-3.9%. No serious complications such as bleeding, loss of airway, pneumothorax or death were observed. Complications occurring during the TLT procedure were exclusively technical and at no time were they life-threatening.

CONCLUSIONS

TLT is a technique with few complications and a straightforward procedure for those familiar with the method. It has some advantages compared with other puncture techniques which appear to commend TLT in terms of safety for the patient.

Tracheotomy: clinical review and guidelines

Tracheotomy is a commonly performed procedure. The Belgian Society of Pneumology (BVP-SBP) and the Belgian Association for Cardiothoracic Surgery (BACTS) developed guidelines on tracheotomy for mechanical ventilation in adults. The levels of evidence as developed by the American College of Chest Physicians (ACCP) were used. The members of the guideline committee reviewed peer-reviewed publications on this subject. After discussion, a proposal of guidelines was placed on the website for remarks and suggestions of the members. Remarks and suggestions were discussed and used to adapt the guidelines when judged necessary. The different techniques of tracheotomy are described. The potential advantages and disadvantages of surgical and percutaneous tracheotomy versus endotracheal intubation are discussed. An overview of early and late complications is given. Low-pressure, high-volume cuffs should be used. The cuff pressure should be monitored with calibrated devices and recorded at least once every nursing shift and after manipulation of the tracheotomy tubes. Inspired gas should be humidified and heated. Regarding the timing of tracheotomy there are not enough well-designed studies to establish clear guidelines. Therefore, the timing of tracheotomy should be individualised. In critically ill adult patients requiring prolonged mechanical ventilation, tracheotomy performed at an early stage (within the first week) may shorten the duration of artificial ventilation and length of stay in intensive care. Percutaneous dilatational tracheotomy (PDT) appears to be at least as safe as surgical tracheotomy (ST) as measured in terms of peri-procedural complications. With PDT, less wound infection is observed. When PDT is compared to ST performed in the operating room, PDT is less expensive, reduces the time between the decision and the performance of tracheotomy and has a lower mortality rate. Different techniques of PDT are discussed. We recommend performing PDT under bronchoscopic guidance. Because of its technical simplicity and short procedure time, the modified Ciaglia Blue Rhino technique is advocated as technique of choice. PDT should be considered the procedure of choice in elective non-urgent tracheotomy. There are some relative contraindications for PDT, but with growing experience, they become less frequent.

PercuTwist: a new alternative to Griggs and Ciaglia's techniques

BACKGROUND AND OBJECTIVE

Tracheostomy is one of the most common procedures in intensive care units worldwide. In this study we aimed to compare three different tracheostomy techniques with respect to duration of procedure and complications.

METHODS

One hundred and thirty patients requiring endotracheal intubation for more than 10 days due to acute respiratory distress syndrome, infections or cerebrovascular events were consecutively selected to undergo the percutaneous dilatational tracheostomy technique (PDT n = 44), the guide-wire dilating forceps technique group (GWDF n = 41) or the PercuTwist technique (n = 45). The time taken to perform the procedure (skin incision to successful placement of tracheostomy tube) and complications were recorded.

RESULTS

The operating times were found to be 9.9 +/- 1.1, 6.2 +/-1.4 and 5.4 +/- 1.2 min in PDT, GWDF and PercuTwist groups, respectively. The duration of the procedure was significantly shorter in the PercuTwist group as compared to the percutaneous dilatational tracheostomy (P < 0.01) and guide-wire dilating forceps (P < 0.05) groups. During postoperative bronchoscopy, eight cases of longitudinal tracheal abrasion (four in the PDT group, two in the GWDF group and two in the PercuTwist group), two cases of posterior tracheal wall injury (one in PDT and one in GWDF) and one case of tracheal ring rupture in the PDT group were seen.

CONCLUSIONS

Percutaneous tracheostomy techniques have their own advantages and complications. PercuTwist, a new controlled rotating dilatation method, was associated with minimal complications, appears to be easy to perform and a practical alternative to percutaneous dilatational tracheostomy and guide-wire dilating forceps techniques.

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.

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.

Prospective evaluation of the retrograde percutaneous translaryngeal tracheostomy (Fantoni procedure) in a surgical intensive care unit: technique and results of the Fantoni tracheostomy

BACKGROUND

Controversy surrounds the safety and practicality of the retrograde percutaneous translaryngeal tracheostomy (Fantoni procedure) compared with other percutaneous methods.

METHODS

We used the Fantoni tracheostomy for 245 patients in our intensive care unit (ICU) over a period of 3 years 6 months and conducted a prospective analysis.

RESULTS

We are able to report a low incidence of complications (1.2%) with the Fantoni procedure. Advantages of the method are reduced tissue trauma and optimal adaptation of the stoma to the cannula, leading to less stomal bleeding and fewer infectious complications. We observed no procedure-related mortality. Under mandatory bronchoscopic control, proper puncture location and cannula placement are ensured, which prevents tracheal wall injury and paratracheal placement of the cannula.

CONCLUSIONS

Our experience shows that the major advantage of the use of the Fantoni tracheostomy is the retrograde dilatation of the stoma, which prevents serious complications compared with other techniques.

Comparison of two percutaneous tracheostomy techniques, guide wire dilating forceps and Ciaglia Blue Rhino: a sequential cohort study

Introduction

To evaluate and compare the peri-operative and postoperative complications of the two most frequently used percutaneous tracheostomy techniques, namely guide wire dilating forceps (GWDF) and Ciaglia Blue Rhino (CBR).

Methods

A sequential cohort study with comparison of short-term and long-term peri-operative and postoperative complications was performed in the intensive care unit of the University Medical Centre in Nijmegen, The Netherlands. In the period 1997–2000, 171 patients underwent a tracheostomy with the GWDF technique and, in the period 2000–2003, a further 171 patients with the CBR technique. All complications were prospectively registered on a standard form.

Results

There was no significant difference in major complications, either peri-operative or postoperative. We found a significant difference in minor peri-operative complications (P < 0.01) and minor late complications (P < 0.05).

Conclusion

Despite a difference in minor complications between GWDF and CBR, both techniques seem equally reliable.

Percutaneous tracheostomy: Ciaglia Blue Rhino versus Griggs' Guide Wire Dilating Forceps. A prospective randomized trial

BACKGROUND

Percutaneous tracheostomy (PT) has gained widespread acceptance to control the airway in patients requiring prolonged mechanical ventilation. Since 1985, new techniques for PT have been described. It was the aim of this investigation to compare two different PT techniques: the Ciaglia Blue Rhino (CBR) and the Guide Wire Dilating Forceps (GWDF).

METHODS

A prospective randomized trial was performed in four intensive care units. After informed consent, 53 consecutive patients were randomized to undergo CBR or GWDF. Procedural complications were evaluated and specific symptoms of the upper airway tract in survivors were assessed.

RESULTS

Twenty-seven patients were randomly assigned to CBR and 26 to GWDF. Patients mean ages were 62.7 +/- 15.8 years and 62.2 +/- 18.3, respectively. Mean APACHE II scores were 20.6 +/- 6.8 and 21.2 +/- 7.2, respectively. Median duration of the procedure was 7 min (range: 4-17 min) with GWDF and 9 min (range: 5-32 min) with CBR (P = 0.16). Seven patients in the group undergoing GWDF had complications (desaturation: two; mild bleeding: one; infected stoma: one; inability to complete the procedure: three). Two patients had complications in the group undergoing CBR (mild bleeding) (P = 0.07). Survivors were followed up after discharge. Three patients (all of them having undergone GWDF) were symptomatic (two with mild hoarseness and one with a persistent foreign body sensation), but laryngotracheoscopy was negative.

CONCLUSIONS

Our results show no differences between both techniques regarding surgical duration or procedural complications. Late symptoms were encountered in three patients undergoing GWDF, however, laryngotracheoscopy failed to document anatomical or functional abnormalities.

Percutaneous dilational tracheostomy techniques

In summary, PDT is a bedside procedure that can be performed with very low morbidity by skilled practitioners. Established methods are undergoing constant evolution and we hope that technical adjuncts are improving patient safety. Evaluation of procedural modifications will require evaluation in randomized clinical trials.

Tracheotomy application and timing

Tracheotomy is one of the most commonly performed surgical procedures among critically ill patients. In the past, tracheotomy was delayed as long as possible in ventilator-dependent patients because of concerns regarding injury to the airway from the surgical procedure. Greater recognition of the benefits of tracheotomy in terms of greater patient comfort and mobility has promoted its earlier performance. No data identify an ideal time for tracheotomy. The decision to convert a patient from translaryngeal intubation to a tracheostomy requires anticipation of the duration of expected mechanical ventilation and the weighing of the expected benefits and risks of the procedure. The convenience of percutaneous tracheotomy performed in the ICU by critical care specialists without formal surgical training has further promoted the adoption of tracheotomy for ventilator-dependent patients. Regardless of the method for performing tracheotomy, meticulous surgical technique and careful postoperative management are necessary to maintain the excellent safety record of tracheotomy for critically ill patients.

Percutaneous tracheostomy with single dilatation technique: a prospective, randomized comparison of Ciaglia blue rhino versus Griggs' guidewire dilating forceps

Percutaneous tracheostomy with single-step dilation technique using Griggs' guidewire dilating forceps (GWDF) is a well-recognized procedure. Recently, Ciaglia has introduced a one-step dilation technique using a curved, gradually tapered dilator, the Ciaglia Blue Rhino (CBR). In a prospective, randomized study, we performed percutaneous tracheostomy in 60 consecutive patients, using either the CBR or the GWDF technique. Postoperatively, all patients had bronchoscopy by a blinded consultant, and stoma characteristics and injuries to the trachea were studied. Mean tracheostomy time (skin incision to insertion of tracheostomy tube) in the two procedures (CBR 7.5 min versus GWDF 6.5 min) was not different (P > 0.05). The GWDF technique was associated with under-dilation and over-dilation of the tracheal stoma, each in almost one-third of patients. In the CBR group, the procedure was associated with a significant increase in peak airway pressure (P < 0.05) in all patients. There were nine cases of tracheal cartilage rupture, three cases of longitudinal tracheal abrasion, and one pneumothorax. Three patients had tracheal in-drawing at the scar site with huskiness of voice at 8 wk after decannulation; however, none had any breathing difficulty. We conclude that the techniques are equally effective in the formation of percutaneous tracheostomy. However, tracheal stoma over-dilation with GWDF and increase in peak airway pressure and rupture of tracheal rings with CBR remain major concerns.

IMPLICATIONS

The tracheas of 60 patients were cannulated through an artificial opening by using a single-step dilation technique with Ciaglia Blue Rhino or Griggs' dilation forceps. The techniques were equally effective for cannulation of the trachea. However, Ciaglia Blue Rhino was associated with rupture of tracheal rings in one-third of patients and increased airway pressure in all, whereas the Griggs' technique was associated with under- or over-formation of the tracheal opening, each in one-third of patients.

Percutaneous tracheostomy with the guide wire dilating forceps technique: presentation of 171 consecutive patients

BACKGROUND

Evaluation of percutaneous tracheostomy (PT) with the guide wire dilating forceps (GWDF) technique.

METHODS

Prospective study of perioperative complications, retrospective analysis of early and late complications in an ICU in a teaching university hospital.

RESULTS

The success rate of the procedure was 96.5%. The average procedure time in 171 consecutive patients was 5.0 min. Perioperative complications requiring surgical or medical intervention occurred in 6.4% of 171 patients. This included conversion to surgical tracheostomy, which was necessary in six patients (3.5%). Major complications while being cannulated occurred in 2.4% of 164 patients but seemed mostly unrelated with the GWDF technique itself. Late complications (after decannulation) were mostly minor and occurred in 22.6% of 106 patients. Only one patient (0.9%) had a symptomatic tracheal stenosis developed.

CONCLUSION

Percutaneous tracheostomy with the guide wire dilating forceps technique is easy to perform at the bedside with few late complications. However, in our study, perioperative and immediate postoperative bleeding complications (minor and major) occur quite often.

Percutaneous tracheostomy: comparison of Ciaglia and Griggs techniques

Endoscopic percutaneous dilatational tracheostomy is at least as safe as standard open tracheostomy in the operating room (OR). Recently, a single dilator was introduced to accomplish dilatation of the tracheal aperture in one step, thus obviating the need for multiple graduated dilators. Experience with endoscopic percutaneous tracheostomy (PCT) using the single dilator in 40 patients to date supports the premise that the procedure is safe, rapid, and technically simple. In the study by Añon et al, two very different techniques, are compared: the Ciaglia percutaneous dilatational tracheostomy technique using multiple dilators and the Griggs percutaneous technique using guidewire-dilating forceps. Although relative complication rates for the two techniques are not significantly different, both procedures are performed in a 'blind' fashion, without the benefit of a bronchoscope. The reported incidence of serious complications in this study is high, and almost certainly avoidable with the addition of direct bronchoscopic visualization. Operative time is reported to be shorter with the Griggs technique, but this finding is unlikely to hold true for the single dilator technique, which reduces procedure time to less than 15 min. This author's experience with bedside endoscopic PCT using the single dilator indicates that it is a safe, rapid and cost-effective procedure with a low complication rate.
