Trauma, Burns and Sepsis Flashcards
what do you do in a patient with decreased breath sounds on one side but otherwise stable?
order CXR and pulse oximetry
tx. of spontaneous PTX in trauma pt
insertion of large diameter chest tube
- insert finger into pleural space prior to inserting the tube to make sure its in the right place
where do you direct a chest tube?
toward the posterior, apical aspect of the pleural space
what is the correct location to insert a chest tube?
bw 4th and 5th intercostal spaces in the midaxillary line
what should happen after insertion of a chest tube correctly?
the lung should re-expand
after insertion of a chest tube, a large amt of air continues to leak into the chest tube over next few hours and lung is still only partially inflated
injury to major bronchus or trachea
- requires partial lung resection to repair
when is observation of a small PTX appropriate?
- not enlarging
- no free fluid in pleural space (i.e. no hemothorax)
- pt is asymptomatic
- pt has not other injuries requiring surgery
if pt has small PTX and requires surgery why must a chest tube be inserted?
assisted ventilation puts positive pressure in lungs which increases the risk of converting a small PTX to a larger one
what signs/symptoms point to tension PTX?
decreased breath sounds on one side
hypotension
JVD
tx. of tension PTX
immediate needle aspiration followed by insertion of chest tube
- get CXR after, not BEFORE
what else can cause hypotension and JVD in a trauma patient?
pericardial tamponade
- do emergent ultrasound and pericardiocentesis and then send patient to OR
initial management of patient with hypotension?
two large bore IV lines with rapid infusion of 1-2 L of NS
can a closed head injury be the cause of severe hypotension?
no.. there is not enough space for the head to hold that much blood and due to the Cushing reflex
when putting in a urinary catheter, you notice blood at the urethral meatus..
do not insert the catheter
- instead assess for possible causes of urethral injury (DRE for prostate); definitive diagnosis with retrograde cystourethrogram
how do you properly assess cervical spine?
- stabilize neck with collar/board
- palpate alone posterior aspect for tenderness or any deformity
- ask patient to move his fingers and toes and to tell you if they can feel you touch them
- order CT scan to R/O injury
what do you do if after insertion of a chest tube, there is 1500 ml of blood evacuated?
thoracotomy - to evaluate for lung hilar injury or injury to the heart
- also do this is rate of blood loss is > 200ml/hr for 3 hrs
what are you worried about with a stab wound just below the clavicle? how should you evaluate?
subclavian artery or venous injury
- if pt is stable do an angiogram
- if pt is unstable, urgent exploration
what are you worried about if there is a penetrating injury below the nipple?
diaphragmatic injury
- need abdominal exploration
pt who was in an MVA has a widened mediastinum on AP CXR - what do you suspect and what test should you order next if pt is stable?
suspect thoracic aortic transection
- order normal PA CXR
what is the next step once you find a widened mediastinum on CXR?
order aortic angiography (gold standard) or CT scan
next step in management in gunshot wound to the abdomen
preoperative radiograph followed by abdominal exploration
when is surgical exploration of the abdomen justified?
- obvious, penetrating injuries
- unstable pts with rapidly distending abdomen or severe abdominal pain
what test should you do next in someone with suspected abdominal injuries but no justification for abdominal exploration who is unstable?
diagnostic peritneal lavage
“positive” diagnostic peritoneal lavage
- > 10 ml gross blood
- > 100 000/ml RBC in lavage fluid
- appearance of vegetable matter or bile
