Brief Summary

Tracheostomy is a commonly performed procedure in Intensive Care and its incidence tends to increase over time as a consequence of the increase in chronic diseases and the average age of the population accessing Intensive Care.

Surgical open tracheostomy (ST) is the standard procedure but has a relatively high incidence of peristomal infections and perioperative bleeding. Percutaneous dilatational tracheostomy (PDT) was introduced in 1985 and has since become a common bedside procedure. Compared to open ST, PDT has the advantages of a lower risk of wound infection, lower bleeding-related mortality, shorter procedure times, and improved cost-effectiveness.

Fiberoptic bronchoscopy is commonly used during PDT to verify the safety of direct tracheal access [5]. However, bronchoscopy-guided PDT has several limitations regarding the precise identification of cervical anatomical structures and the prevention of complications such as vascular injury.

Preliminary ultrasound examination of neck anatomy has numerous potential benefits, including increased safety during the procedure, identification of cervical vascularization, and localization of the tracheal puncture site with lower risk of complications [6-8]. Several studies have shown that the use of ultrasound in a preliminary and real-time manner can improve first-pass success rate and puncture accuracy, reduce procedure time, and complications.

The objective of this study is to map the arterial and venous vascular anatomy of the neck in order to identify points with a lower risk of vascular injury during PDT. This helps prevent bleeding during tracheostomy, which is one of the major complications associated with the procedure.

Conditions

Tracheostomy Complication; Trachea

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Patients undergoing surgical procedure

The following variables will be collected: age, weight, height, gender, previous neck surgery/radiotherapy, previous tracheostomy.

Subsequently, through ultrasound examination, the vascular anatomy of the neck will be studied by dividing it into twelve anatomical quadrants: Four medial quadrants (thyroid membrane, cricoid membrane, and cricothyroid membrane; first tracheal ring, from the beginning of the second tracheal ring to the end of the third tracheal ring), laterally on both right and left sides of each quadrant, the lateral quadrants will be identified. An ultrasound examination with a linear probe with doppler technique will be performed for each quadrant to identify the vascular structures.

For each quadrant, the presence of vessels, arterial or venous nature, and their diameter will be collected.
