Percutaneous dilatational tracheostomy (PDT) is a commonly performed procedure in critically sick patients. It can be safely performed bedside by intensivists.This has resulted in decline in the use of surgical tracheostomy in intensive care unit (ICU) except in few selected cases. Most common indication of tracheostomy in ICU is need for prolonged ventilation. About 10% of patients requiring at least 3 days of mechanical ventilator support get tracheostomised during ICU stay. The ideal timing of PDT remains undecided at present. Contraindications and complications become fewer with increase in experience. Various methods of performing PDT have been discovered in last two decades. Preoperative work up, patient selection and post tracheostomy care form key components of a successful PDT. Bronchoscopy and ultrasound have been found to be useful procedural adjuncts, especially in presence of unfavorable anatomy. This article gives a brief overview about the use of PDT in ICU.

   Introduction Top

Tracheostomy is one of the oldest and most commonly performed procedures in critically sick patients. Surgical tracheostomy (ST) was first described by Jackson in 1909. Its use in Intensive Care Unit (ICU) gained popularity during polio epidemic in the 1950's. Percutaneous dilatational tracheostomy (PDT) over a guidewire was invented by Ciaglia in 1985. PDT has now become the standard of care in ICU and has replaced ST in this subset of patients to a large extent. It however remains imperative to be aware of conditions where ST may be preferable. Over the last few years, the original Ciaglia PDT technique has undergone modifications, and multiple other techniques have also evolved. [1],[2]

   Definitions Top

Tracheostomy is process of creating an opening in the anterior wall of trachea.

ST refers to placement of a tracheostomy cannula under direct vision after dissection of pretracheal tissues and incision of tracheal wall.

PDT involves blunt dissection of pretracheal tissues followed by dilatation of trachea over the guidewire and insertion of tracheal cannula using Seldinger technique. [3],[4]

   Indications for Percutaneous Dilatational Tracheostomy Top

PDT in ICU is classically indicated (1) to facilitate weaning in difficult to wean patients, (2) to aid in tracheobronchial toileting, (3) to protect airways in patients at risk of aspiration, (4) in anticipated prolonged ventilator stay, and (5) to minimize sedation requirement. PDT is generally avoided as an emergency intervention unless performed by an experienced operator. In case of difficult to intubate patients' emergency, cricothyrotomy is considered as the procedure of choice.

The list of contraindications [5],[6],[7] shortens as the operator's experience increases [Table 1].

Tracheostomy versus prolonged translaryngeal endotracheal intubation

Prolonged ventilatory stay is the most common indication of tracheostomy in critically ill patients. Up to 24% of mechanically ventilated patients in ICU undergo tracheostomy. Tracheostomy, however, has not shown to have any clear-cut benefits, in terms of mortality or laryngotracheal complications, when compared to translaryngeal intubation. Tracheostomy has been conventionally recommended for patients requiring ventilator for >21 days, and endotracheal (ET) intubation is recommended if ventilatory stay is <10 days. This was as per the first consensus on artificial airways published in 1989, for patients on mechanical ventilation. [8] Most of the recent guidelines have found insufficient evidence to make any concrete recommendations in this regard. [3],[7] When compared to translaryngeal intubation, tracheostomy is associated with less sedation, better patient comfort, reduced work of breathing aiding in faster weaning from ventilator.

Timing of tracheostomy in Intensive Care Unit

Best of evidence, in the form of randomized controlled trial (RCT), does not show any benefit of early (<10 days of intubation) when compared to late tracheostomy (>10 days of intubation). No benefit has been observed in terms of mortality, ventilator-associated pneumonia, laryngotracheal complications, and ICU length of stay. Some benefit has been observed in the form of reduced ventilatory stay. Recent guidelines have found insufficient evidence at present for any recommendation to be made regarding this. [3],[7]

Surgical versus percutaneous tracheostomy

Recent years have seen extensive use of PDT in ICU, almost supplanting ST. This is secondary to easy execution of PDT at patient's bedside avoiding unnecessary, and at times high-risk transfers to operation theater, and last but not the least, cost-effectiveness. A morbidity of 13%-33% has been observed related to transport of critically ill patients, affecting management significantly in 25% of patients. [9],[10] A meta-analysis was conducted in 2006 including 17 RCTs with total of 1212 patients. It found less incidence of wound infection of 2.3% compared from 10.7% associated with ST. Many have attributed it to minimally invasive nature of PDT. [11] Similar findings were also reported in a meta-analysis conducted by Higgins and Punthakee. [12]

A recent meta-analysis of Putensen et al. in 2014 included 14 RCTs with 973 patients. They found PDT to be associated with less incidence of stromal inflammation and infection but higher incidence of technical difficulties when compared to ST. [13] Major guidelines recommend PDT as the procedure of choice in critically sick patients. [3],[7]

Scarce literature exists regarding the cost-effectiveness of bedside performed ST versus PDT. Data are insufficient to draw any conclusion regarding this. [3]

It is however worth keeping in mind that ST may be safer if anatomical landmarks are difficult to palpate, or there is a malignancy at the site of insertion, and if emergency, tracheostomy placement is required. [14]

Complications of percutaneous dilatational tracheostomy

Similar complications are seen with both ST and PDT. These have been divided into immediate or early (0-7 days of procedure) and late (beyond day 7) complications [Table 2].

There is a paucity of long-term follow-up studies regarding complications related to ST and PDT at present. [7],[14],[15] Proper patient selection remains the key component in preventing complications.

   Anatomy Top

Before proceeding with tracheostomy, it is essential to have a thorough knowledge of neck anatomy [Figure 1]. Hyoid bone is the most stable portion of the airway and is easily felt when palpating from chin downward in the midline. Thyroid cartilage is felt next followed by cricothyroid membrane and cricoid cartilage. Tracheal rings can be palpated below the cricoid cartilage. Tracheal rings become difficult to appreciate as trachea descends into the chest. Jugular or suprasternal notch is felt as an angle at the junction of neck and chest. Cervical length of the trachea varies with spinal curvature, body build, extension-flexion of the neck, and anteroposterior diameter of the chest. In young adults, nearly half the trachea resides in the neck region and it increases up to two-thirds with neck extension. In older adults, tracheal length in the neck may be reduced to one third. Suprasternal length of the trachea is also reduced if patients have kyphosis, limited neck mobility like in ankylosing spondylitis, and morbid obesity.

Tracheostomy is normally performed between second and third tracheal rings. Some investigators have found tracheal puncture between third and fourth tracheal rings to be associated with a lower rate of injury to aberrant vessels, especially in the presence of anatomical abnormalities. Trachea is roughly 2-2.5 cm deep from the skin at the suggested insertion site, and this depth increases on moving downward to thoracic area. Tracheal slant from the vertical also increases as it descends into the chest which is more marked in older population. These anatomical changes are important to keep in mind while selecting an appropriate level for PDT, especially in older individuals.

Another important consideration is the esophagus which lies posterior to trachea in its entire course, except near carina where it is positioned slightly to the left. For all practical purposes, any injury to the posterior tracheal wall would also cause damage to the esophagus. Special attention needs to be paid to thyroid isthmus, which normally crosses second and third tracheal rings. Similarly, lateral lobes of thyroid also are closely situated. This area has a rich vascular supply and therefore predisposed to bleeding risk. Conventionally, midline is thought to be devoid of larger veins or arteries, but it is not always so. This knowledge has encouraged use of ultrasound for PDT. [16],[17],[18],[19],[20],[21]

Percutaneous dilatational tracheostomy techniques

Percutaneous techniques were initially described in the mid-1980s by Ciaglia et al. Over the last two decades, it has undergone multiple modifications and some other alternatives have also come up. So far, there is no solid evidence favoring one technique over another.

   Ciaglia Serial Dilatational Technique Top

Ciaglia et al. in 1985 carried out the first bedside PDT with the help of multiple sequentially larger dilators over the guidewire. This technique has undergone three major changes since then, in terms of level of tracheal interspace cannulation, use of concurrent bronchoscopy, and use of a single tapered dilator. The site of insertion has moved caudal from cricoid cartilage by one or two tracheal interspaces.

   Ciaglia Single Dilator Tracheostomy Top

It is popularly known as Ciaglia Blue Rhino (Cook Critical Care, Bloomington, IN, USA). It was introduced in 1999, more than a decade after initial description of Ciaglia technique. It is a simpler kit than the original kit and entails use of a single-beveled curved hydrophilic dilator. Use of single dilator is associated with reduced tidal volume loss during the procedure as change in dilator is not required. Similar to Blue Rhino, Portex Ultraperc single-stage dilator was developed by Smith Medical [Figure 2].

   Griggs Percutaneous Technique Top

This technique was developed by Griggs et al. in 1990. It is also known as guidewire dilator forceps technique. The Portex Griggs percutaneous dilatational tracheostomy kit (Smith Medical) uses a specially designed forceps (modified Howard Kelly forceps) over the guidewire to result in single step dilatation of tissues in the pretracheal and tracheal space by spreading the forceps. The dilating forceps is designed to slide over the guidewire for the purpose. Following the dilatation, tracheostomy tube is inserted over the guidewire into the trachea. This technique has lost its popularity due to higher incidence of soft tissue damage. It may be useful in places with resource constraint as forceps can be reused and no special kit is required.

   Fantoni Translaryngeal Tracheostomy Top

This was first described by Fantoni and Ripamonti in 1997. It is little cumbersome to perform and involves passage of guidewire retrogradally through the vocal cords after needle puncture of trachea. This is followed by railroading the combined dilator and tracheostomy tube over the guidewire into the larynx and out through the anterior tracheal wall. Tracheostomy tube is then separated from the dilator and rotated by 180° such that it faces the carina. This procedure requires an experienced operator.

Frova's percutaneous tracheostomy

This involves use of a single-step screw-type dilator and is commercially available as the PercuTwist kit (Rusch, Kernen, Germany). It was first described in 2002. The dilator is rotated clockwise using a lifting motion over the guidewire. Earlier case reports had described tracheal ring fractures and posterior tracheal wall damage with this technique. However, it seems to be associated with better control over the dilating maneuver right from the start to end of procedure.

Balloon dilatational tracheostomy (Ciaglia Blue Dolphin, Cook Medical)

It is the second generation of Ciaglia technique. Inflation of a modified angioplasty balloon over a guidewire is used to dilate the trachea. The tracheal stoma is made by inflating the balloon with saline to 11 atmospheric pressure for 15 s. Then, the balloon is deflated and the tracheostomy tube insertion is done in a single step. This is an advantage over conventional single dilator PDT where the dilator needs to be removed before inserting the tracheostomy tube. There is a presumption that balloon dilation minimizes the pressure on the tracheal wall as compared to other techniques. [2],[22],[23],[24],[25],[26],[27]

As the experience with PDT is increasing, intensivists are venturing into performing the procedure in obese patients as well. Conventionally, it had been difficult in morbidly obese population, especially while inserting a longer adjustable flange tube as a suitable loading dilator was not available. Now, it is smoother as two new kits with longer stoma dilation and adjustable flange armored tracheostomy tubes have been introduced recently (UniPerc, Smith Medical Kent, UIL and Expert set, TRACOE Medical GmbH, Frankfurt, Germany). [28]

Comparison of different percutaneous dilatational tracheostomy techniques

Each technique of PDT has its own set of characteristics and advantages. Many comparative studies have been conducted, but they are largely heterogeneous and with small sample size. A recent meta-analysis in 2012 had included 13 studies which compared at least two PDT techniques. No major differences were found between various techniques, except for the Fantoni technique. Fantoni technique was found to be associated with more serious complications with the need to convert to an alternative PDT technique. Ciaglia Blue Rhino technique fared better than other PDT techniques such as PercuTwist, Blue Dolphin, and Griggs technique. [29],[30],[31],[32]

Practical aspects of percutaneous dilatational tracheostomy

The key aspect of preoperative planning is proper patient selection after thorough anatomical and physiological examination. Anatomical landmarks should be easily palpable, and there should be a space of at least 3-4 cm between the cricoid cartilage and the sternal notch. Once PDT is found to be feasible, informed consent should be taken. Special care should be taken to withhold anticoagulation if any. Patient should be nil by mouth as per common protocol. Continuous monitoring with blood pressure, electrocardiogram, pulse oximetry, and capnography is done throughout the procedure.

PDT can be performed under local anesthesia but is generally performed under adequate analgesia, sedation, and muscle relaxants sometimes. Most of the times, the patient is already intubated. Neck is properly positioned and adequately extended with help of a roll placed under the patient's shoulders [Figure 3]. The incision point is typically located half way between the cricoids cartilage and sternal notch. [Table 3] describes the surgical procedure in detail.

Use of bronchoscope during the procedure has certain obvious advantages such as real-time confirmation of needle placement, midline position of the needle, tube placement, and avoidance of posterior tracheal wall injury. There have however been concerns regarding its routine use. It has been found to be associated with measurable increases in intracranial pressure and alveolar derecruitment related fall in oxygen saturation. It should be thus used with caution in patients with acute neurological condition and high ventilator requirements. Most of the guidelines do not recommend routine use of bronchoscope as there are insufficient data at present. However, it is usually considered essential if operator is inexperienced and if there is a difficult neck anatomy. Some authors prefer use of a Bonfils semirigid scope over flexible scope to prevent needle damage to the scope during the procedure [Figure 4].

This has been increasingly used in recent times to estimate the distance from skin to the trachea. This ensures the accurate placement of the introducer needle into the trachea. Preoperative identification of aberrant vessels and enlarged thyroid isthmus with ultrasound helps in avoiding complications. Its use has been found to change the intended tracheostomy site in about 24% of cases. It is an inexpensive and readily available bedside modality. It can also be used to localize tracheal rings and in ensuring midline punctures. Currently, further studies are required to recommend its routine use during PDT. [3],[7],[33],[34],[35],[36],[37],[38],[39],[40],[41],[42] It however can be useful in patients with anatomical abnormalities or those who are morbidly obese. A retrospective study in 2014 did not find any difference in complication rates between ultrasound-guided and bronchoscopy-guided PDT procedures [Figure 5]. [41]

Use of laryngeal mask airway during percutaneous dilatational tracheostomy

Fear of inadvertent ET tube cuff puncture and accidental extubation have prompted clinicians to use laryngeal mask airway (LMA) during PDT. However, its safety in critically sick patients with significant ventilator requirements is questionable. As of now, there is insufficient evidence to recommend use of LMA during PDT. [3],[14],[43],[44],[45]

Posttracheostomy care

Optimal posttracheostomy care is of utmost importance. Attending staff should ensure that stoma wound is kept clean and dry at all times. Tube cuff pressure should be maintained in the range of 20-25 mmHg. Cuff pressure >25 mmHg is associated with risk of mucosal ischemia. Moreover, cuff pressure <15 mmHg leads to leak and risk of microaspiration. A heat and moisture exchange filter should be used for adequate humidification. Tracheal suction should be done gently and timely. Excessive suctioning leads to mucosal trauma and inadequate suctioning increases the risk of tube blockage. [46],[47]


Need to continue with tracheostomy tube should be assessed on a daily basis. Decannulation should be attempted as soon as possible. Decannulation should be considered if patient has effective cough effort, is able to protect upper airway, has reasonably low FiO2 requirement, has low suction requirement and mechanical ventilation has not been needed for at least 24-36 h. It should be deferred if patient is delirious or agitated to avoid airway compromise.

There are several methods available to attempt weaning from tracheostomy tube such as progressively decreasing the size of tracheostomy tube, using a tracheostomy plug (known as tracheostomy button), or progressive capping of fenestrated tracheostomy tube until tolerated for about 48 h. [7],[48],[49],[50],[51],[52]

   Comclusions Top

PDT is an established procedure in critically ill patients. Nuances of the procedure are better appreciated with increase in experience. Proper patient selection and wide use of ultrasound or bronchoscope decrease failure rates and complications. One should stick to the technique with maximum individual comfort as there is no evidence of superiority among various techniques. Posttracheostomy care and decannulation are important components in the management of a tracheostomized patient.
