A family member responsible for the patient was contacted for informed consent prior to the procedure. Data were obtained prospectively (data collecting sheet) at the Risoleta Tolentino Neves University Hospital

Trauma Center (affiliated to the Universidade VX-680 chemical structure Federal de Minas Gerais) from June 1, 2010 to March 31, 2011. Inclusion criteria were age 18 years or older and an indication for tracheostomy. All percutaneous tracheostomies, as well as, ultrasound and bronchoscopy were performed by the authors JBRN, AJO, MPN. General surgery residents of the Federal University of Minas Gerais performed the procedure under supervision. Data included demographics, indication for tracheostomy, body mass index selleck kinase inhibitor (BMI),

thyromental distance (measured from the thyroid notch to the inferior border of the mentum), tracheostomy tube size (internal diameter), and acute complications. Procedure time was recorded by a nurse with a digital stopwatch. It is our practice to correct the coagulation parameters of the patients prior to percutaneous tracheostomy. Therefore, we also reviewed the data pertaining to prothrombin time, activated partial prothrombin time, platelet count, and the international normalized ratio (INR). Modified Percutaneous Tracheostomy Technique The instruments used for percutaneous tracheostomy in this work were manufactured from stainless steel and are reusable (Figure 1). All mechanically ventilated patients are sedated (midazolan 1-2 mg and fentanyl Selleckchem Erismodegib 100-200 mcg), paralyzed (pancuronium 0.04-0.1 mg/Kg), and placed on 100% oxygen starting 5 minutes before and until 5 minutes after the completion of the procedure. Positive end expiratory pressure (PEEP) setting is not changed for the procedure. A pulse oximeter (Datex-Ohmeda

Inc., Tewksbury, MA) is used to assess hemoglobin oxygen saturation. Trauma patients with cervical spine cleared by physical examination in addition to radiograph of the neck and/or computed tomography scan, have their neck slightly extended by a 10 cm high pillow placed underneath ADP ribosylation factor the shoulders. Otherwise, the patient’s neck and the bed are maintained in neutral position. If the cervical collar has to be removed a head immobilization device is used to stabilize the cervical spine (HeadBed™ II, Laerdal do Brasil, Barueri, SP, Brazil).

The operative site is prepared with 10% povidone iodine solution and infiltrated with 2% lidocaine (Astra Zeneca, Sao Paulo, Brazil);10 mg/Kg maximum dose. Ultrasound of the neck is performed with an 8 MHz Ultrasound Vascular Probe (Toshiba Nemio XG, Toshiba America Medical Systems, Inc.
