What are the boundaries of the safe triangle for chest drain insertion?
What are the boundaries of the safe triangle for chest drain insertion?
The boundaries of the safe triangle are: the lateral edge of pectoralis major, the lateral edge of latissimus dorsi and the line of the 5th intercostal space.
What are the borders of the safe triangle?
A “safe triangle” (shown below) has been described as the preferred site of insertion. This is the triangle bordered by the anterior border of the latissimus dorsi, the lateral border of the pectoralis major muscle, a line superior to the horizontal level of the nipple, and an apex below the axilla.
Why is chest tube insertion in 5th intercostal space?
Placement: A thoracostomy tube is usually placed between the mid to anterior axillary line in the fourth or fifth intercostal space tracking above the rib so as not to injure the intercostal bundle (artery, vein, nerve).
What intercostal space does a chest tube go?
The most appropriate site for chest tube placement is the 4th or 5th intercostal space in the mid- or anterior- axillary line. Attention to technique in placing the chest tube is vital to avoid complications from the procedure.
What is Triangle auscultation?
The triangle of auscultation is a relative thinning of the musculature of the back, situated along the medial border of the scapula which allows for improved listening to the lungs.
Why it is called safe triangle?
This area is known as the “triangle of safety”—bordered by the anterior border of the latissimus dorsi, the lateral border of the pectoralis major muscle, a line superior to the horizontal level of the nipple, and an apex below the axilla. The British Thoracic Society (BTS) guidelines clearly detail this triangle.
What shape is a triangle?
In geometry, a triangle is a closed, two-dimensional shape with three straight sides. A triangle is also a polygon.
Why is a triangle safe?
It is the preferred site for chest tube insertion, as it minimizes the risk of injury to internal organs, vascular structures such as the internal mammary artery, muscles and breast tissue [2]. However, complications associated with insertion of chest tube drainage in the ‘safe triangle’ are also known.
What structure separates the floor of the triangle from the lungs?
The diaphragm is the most important muscle of respiration, and separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity: as the diaphragm contracts, the volume of the thoracic cavity increases, creating a negative pressure there, which draws air into the lungs.
What is the proper placement of chest tube?
5thintercostal space at the midaxillary line (note: in most patients this is lateral to the nipple at the point of the midaxillary line)
What is the safety triangle?
Safety Triangle. Definition – What does Safety Triangle mean? The Safety Triangle, also known as the Safety Pyramid, the Heinrich Triangle, and the Bird Triangle, is a theoretical model that describes a stable ratio between workplace incidents of varying degrees of severity.
What is a surgical chest tube?
It is a plastic tube that is put through the side of your chest. It uses a suction device to remove air, blood, or fluid from around your heart or lung. A chest tube will help you breathe more easily.
