== AFAST Abdominal Focused Assessment in Trauma/Triage ==
Developed as a technique for quick assessment in emergent patients. Only novice ultrasound skills are necessary to begin utilizing this tool.
Procedure
Right lateral recumbency
Place probe in 4 areas and assess if free abdominal fluid is present or not. For each position, give a score of 1 or 0.
Positions are as follows:
DH view (Diaphragmatic/Hepatic view)
Probe is placed with ultrasound marker ventral on left side of screen.
Organs to be identified:
Caudal lung margin - can evaluate for pulmonary edema, nodules, pneumonia, PTE
Diaphragm - Evaluate for hernia
Liver - Evaluate for general liver size, echogenicity, obvious masses
Gall bladder - Evaluate for mucoceole, wall edema consistent with anaphylaxis
Peritoneal cavity - evaluate for free fluid
Caudal vena cava - evaluate size as it crosses the diaphragm. Collapsed - hypovolemia. Distended - R sided CHF vs volume overload. Expand and contract by 50% diameter is normal
Hepatic veins - distended consistent with volume overload or R sided CHF
Thoracic cavity - evaluate for pleural effusion
Pericardial sac - Evalaute for pericardial effusion
Heart apex +/- chambers - general idea of size and filling
