The “safe triangle” as illustrated in figure: 1 is 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 the triangle of safety used?
The triangle of safety is an anatomical region in the axilla that forms a guide as to the safe position for intercostal catheter (ICC) placement.
What is safety triangle for chest tube?
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.
What is the triangle of safety for chest drain insertion?
Inserting the drain This area is commonly known as the “safe triangle”, bordered by the anterior border of latissimus dorsi, the lateral border of the pectoralis major, a line superior to the horizontal level of the nipple and an apex below the axilla. The drain should be inserted just above the rib.
What passes through auscultation triangle?
[1] The floor of the triangle consists of the posterior thoracic wall which contains the rhomboid major muscle, serratus anterior muscle, and erector spinae muscles. The triangle of auscultation is an important anatomical landmark that allows for better auscultation during the pulmonary examination.
What are the boundaries of triangle of auscultation?
It has the following boundaries: Superiorly and medially, by the inferior portion of the trapezius. Inferiorly, by the latissimus dorsi. Superiorly and laterally, by the medial border of the scapula.
Who invented the safety triangle?
A: In the 1930s, Herbert Heinrich first theorized that severe injuries often occur after many less severe injuries and near misses, and that these events occur in a fixed ratio of 300 near misses to 29 less severe injuries to 1 major injury—the famous safety triangle.
Do junior doctors know where to insert chest drains safely?
Background: The safe insertion of a chest drain is a skill doctors across specialties require. Results: Of the 55 junior doctors surveyed, 45% were outside the safe area of chest drain insertion as defined by the British Thoracic Society. The most common error was a choice of insertion site too low (24%).
What is green triangle for safety?
Green triangle indicates sole puncture protection with a Grade 1 protective toecap. For heavy industrial work environments, especially that of construction where sharp objects (such as nails) are present. Yellow triangle indicates sole puncture protection with a Grade 2 protective toecap.
What is the triangle of auscultation?
The triangle of auscultation is at the inferior angle of the scapula best exposed by instructing the patient to cross his arms over his chest and bending forward. As a result, there are fewer impedances between the examiner’s stethoscope and the lungs which allow for better auscultation.
What does it mean if a chest drain is swinging?
Swinging – The pleural space is intra-thoracic, and therefore, changes pressure during respiration. Thus, if a chest drain is in continuous connection with the pleural space, it will change pressure.
Where is the posterior triangle of the neck?
The posterior triangle of the neck is an anatomical area located in the lateral aspect of the neck.

What is an accident triangle?
The accident triangle, also known as Heinrich’s triangle or Bird’s triangle, is a theory of industrial accident prevention. It shows a relationship between serious accidents, minor accidents and near misses and proposes that if the number of minor accidents is reduced then there will be a corresponding fall in the number of serious accidents.
