Diastolic dysfunction associated with peri- and post-operative complications. Propofol and cardiovascular depression. Some studies report that propofol worsens diastolic function, others report improvement.
SVV is the change in stroke volume during inspiration and expiration due to changes in intrathoracic pressure and consequent variations in venous return. SVV to assess fluid status and guide intraoperative fluid management. SVV utility was established using TV of 8 ml/kg while ARDSNet recommendations suggest 6 ml/kg is preferable.
Vertebral compression fractures (VCF) from trauma, osteoporosis, or pathologic reasons are a significant cause of severe pain and decreased functionality, both of which pose a considerable functional and financial burden to the patient.
Assess the efficacy of ultrasound, a more accessible point of care modality, to describe the dimensions of the epidural space. Determine the reliability of ultrasound for measuring cervical and lumbar epiduralspaces for ESIs in chronic pain patients and compares these to MRI measurement.
