Capnothorax
SRNA looking for thoughts on a case today.
Patient had no respiratory history, normal EF, and normal hemodynamics after induction. During robotic fundoplication, the patient became persistently tachycardic and hypotensive enough to require a vasopressor infusion. Towards end of case I was on around 70% FiO2 with 8 of PEEP. Sats were in low 90’s
At the end of the case, I noticed significant subcutaneous emphysema with periorbital swelling. That made me concerned that the earlier hemodynamic and respiratory changes may have been from a CO₂ capnothorax with tension physiology.
In PACU, the patient was still requiring 8 L O₂ and saturating around 90%, so I suggested a CXR. Patient was still tachy and hypotensive, and uncomfortable from all the gas.
Would you consider that overall picture concerning enough for capnothorax/tension physiology? Would you get a CXR or lung ultrasound postop with that persistent oxygen requirement?
