Can Ultrasound rule out a pneumothorax?

Clinical Scenario

You are allerted for a level 3 trauma from the mountain, a cyclist has fallen going down hill.

You prepar the shock room with everything you may need, dress up, and wait.

A 25 y/o cyclist arrives completely immobilized, you immidiately start to  perform ABCDE as you learned in your recent ATLS course (you feel confident).

First stop is a possible problem in “B” (breathing): he has an ecchimosis on the right emithorax, not crepitation, maybe there is a less vescicular murmur on the same side, but you are not sure (the shock room is very crowded an noisy!), he is slightely tachypnoic (RR is 24), O2 saturation is 96%. …you go on….in “E” (Exposure) you find an exposed, bleeding, thigh bone fracture that surly is going to need surgery, at the moment you stop the bleeding, stabilize, allert orthopedic…ect…

FAST is normal. You ask for X-Ray : anteroposterior (AP) chest x-ray, pelvis and thigh bone. Confirmed exposed fracture, no signs of pneumothorax, surgery room is ready…

You recently have reeded the previous post and you don't feel confident about a negative thorax x ray, so you decide to “extend” your FAST and on the right emithorax you find a "lung point"...

are you going to let this patient be intubated?

Thoracic trauma and chest X-Ray

Clinical Scenario

You are alerted for a level 3 trauma coming from the mountain, a cyclist has fallen going down hill.

You prepare the shock room with everything you may need, dress up, and wait.

A 25 y/o cyclist arrives completely immobilized, you immediately start to  perform ABCDE as you learned in your recent ATLS course (...you feel confident).

First stop is a possible problem in “B” (breathing): he has an ecchimosis on the right emithorax, not crepitation, maybe there is a less vescicular murmur on the same side, but you are not sure (the shock room is very crowded an noisy!), he is slightely tachypnoic (RR is 24), O2 saturation is 96%. …you go on….in “E” (Exposure) you find an exposed, bleeding, thigh bone fracture that surly is going to need surgery, at the moment you stop the bleeding, stabilize, allert orthopedic…ect…

FAST is normal. You ask for X-Ray: anteroposterior (AP) chest x-ray, pelvis and thigh bone. Radiologist confirms exposed fracture, no signs of pneumothorax, surgery room is ready...

…Do you still feel confident?

Chest X-Ray and aortic dissection

Clinical Scenario 

A 70 yo man come to the ED for restrosternal chest pain and shortness of breath during minimal activity in the last days. He is an ex smoker, with a history of hypertension. On physical examination the patient is not in distress, with a regular blood pressure and regular oximetry. ECG shows no evidence of ischemia. You first think about coronary artery disease, but you also want to exclude an aortic dissection. In Radiology the patient remaine seated and receive an anteroposterior (AP) chest Xray: maximal mediastinal width (MW) is 8,80 cm (the optimal cutoff level is 8,65 cm), no other signs. 

Shall you worry?

Is CRP correlated to CT result in the evaluation of abdominal pain?

A 74 yo/man complained of diffuse abdominal pain. The pain was intermittent and accompained by vomiting. He has no history of abdominal pain or abdominal surgery.

On examinations the patient presented non icteric, afebrile, not tachicardic. 

The abdomen was mildly distensed with midline tenderness. 

The US evidenced a normal aorta diameter. 

Abdominal x ray showed non specific bowel gas pattern. 

CRP value was 7 mg/L.

The radiologist says it is a little value to perform an abdominal CT, we see tomorrow…..

How LR works. Why any test is unnecessary for a patient with very low-risk chest pain ?

A 40 yo truck driver, presented in ED with substernal chest pain. He is healthy, no family history of CAD. Held for observation, serial ECG have not modified, not elevated troponin.

Is an Exercise Treadmill Testing useful (ETT)? Or a Myocardial Perfusion Imaging (MPI) is better ?

Does Murphy’s sign and sonographic Murphy sign have the same clinical utility?

A 40 yo woman presented to the ED with upper quadrant pain since three hours after eating a tasty pizza. She is overweight, she presents feverish (38°C) her skin is nonicteric. The abdomen is soft, there is tenderness on the upper right quadrant, you perform a deep palpation in the subcostal area, and the patient stops breathing for pain. 

Is Murphy’s sign useful to make diagnosis of cholecystitis? What about the sonographic Murphy’s sign?
