Point of care ultrasound and sub-xiphoid window reduce uncertainty in the management of potential dual-cavity injuries in patients with torso stab wounds.

Patients with torso stab wounds and potential injuries above and below the diaphragm are challenging to manage. The highly structured clinical algorithm of the ATLS course should be complemented by the use of point of care ultrasound and sub-xiphoid window to assess the pericardium. These adjuncts reduce the likelihood of negative exploration and incorrect operative sequencing.
