Cantral lines should not be placed near the brachiocephalic valves because …
accurate CVP estimate
report and consequences 2m
potential breach of visceral pleura and once removed cause a pneumothorax
NG in the rt costophrenic angle via the right main bronchus
What are the possible risks of right sided central lines? 3 m
- Arrythmias
- Cardiac perforation
- Cardiac temponadeCardiac tamponade is a serious medical condition in which blood or fluids fill the space between the sac that encases the heart and the heart muscle. This places extreme pressure on your heart. The pressure prevents the heart’s ventricles from expanding fully and keeps your heart from functioning properly.
describe the effected segment of lung
flail segment - needs cardiothoracic assistence - multiple rib fractures and re- expansion problems
report
lamella pleural eff - fluid trapped between lung ans visceral pleura
ETT is ideally placed at?
4cm
how can pmneumoperitoneum be seen on a axr
riglers sign 2nd image triangle of gas in the upper right quadrant
The Rigler sign, also known as the double-wall sign, is a sign of pneumoperitoneum seen on an abdominal radiograph when gas is outlining both sides of the bowel wall, i.e. gas within the bowel’s lumen and gas within the peritoneal cavity.
ETT can be effected by patients head position. True or false
True
what defines a tension pneumothorax? 3m
- Mediastinal shift
- flattened/ eversion/ depression diaphragm
- hypeexpanded hemithorax
Tracheostomy purpose?
Prolonged need for ventilation
prevent tracheal stenosis
Tracheal diameter should be
2/3 tracheal diameter
How do you know the Subclavian vein has had correct cannulation?
Beneath or behind the clavicle
if above clavicle arterial puncture of extravascular placement
Remember to look for pneumothorax
report rta 3m
- widened mediastinum hx trauma - in other patients can be a nonspecific finding. No aortic knuckle - mediastinal haematoma
- pulmonary contusion
- fractured left clavicle.
- extra pleural cap - blood tracked into the superior sulcus
The most common infective causative agents are :
Other uncommon agents are:
Legionella pneumophila 3
Mycobacterium tuberculosis
- Streptococcus pneumoniae: pneumococcal pneumonia- floxicillin
- Klebsiella pneumoniae: Klebsiella pneumonia
- Pseudomonas aeruginosa: pseudomonas pulmonary infection
- Staphylococcus aureus
