[Percutaneous tracheostomy]

The aim of this study was to evaluate the different techniques of percutaneous tracheostomies, their advantages, drawbacks, complications and to compare them to standard surgical tracheostomies. This study will consider only elective (non emergency) bedside procedures in intensive care units.

Extraction from Medline database of english and french articles on percutaneous tracheostomies and searching along with major review articles.

The collected articles were selected according to their qualities regarding to their evidence level. In addition to several important or historic references, the literature of the five past years was studied.

The articles were reviewed according to their contribution for techniques, perioperative and postoperative complications, recent advances, advantages and drawbacks of all procedures. Publications addressing recent comparisons between surgical and percutaneous tracheostomies were specially studied.

Four techniques of bedside percutaneous tracheostomies are available and marketed, in France: Ciaglia's dilation technique (with multiple or unique dilator), Griggs's technique (using a special designed forceps), and Fantoni's technique (Trans Laryngeal Tracheostomy). The most spred but also first described technique is the Ciaglia's (1985). The most recent articles comparing surgical and percutaneous tracheostomies techniques are not able to demonstrate a superiority of one of them in terms of feasibility or safety. In other words, there should be a slight advantage for the percutaneous tracheostomy regarding to the late post-operative complications, as there should be a slight advantage for the surgical techniques regarding to the perioperative complications. The literature analysis point out firstly the learning curve for percutaneous dilational tracheostomy, with a significant decrease of complication incidence with the operator's experience and secondly the continuous endoscopic guidance seems to increase the safety of the percutaneous procedure.

Since there has been a great deal of percutaneous tracheostomy in the intensive care units, the incidence of tracheostomy have increased in those services. There is a trend to replace the surgical procedure by the percutaneous one. However, according to the potentially jeopardizing complications, percutaneous tracheostomy should be done by an experienced operator with the help of a continuous endoscopic guidance.
