入选标准
- •Patient clinically meets indication for peripheral lung nodule biopsy and has been scheduled for robotic bronchoscopy.
- •Lesion Criteria:
- •Pulmonary nodules of 8-50mm in largest dimension.
排除标准
- •Patients with known bleeding diathesis; Platelet count < 50,
- •Current use of systemic anticoagulation or antiplatelet therapy without the ability to hold therapy for the recommended amount of time prior to an invasive procedure (aspirin monotherapy is acceptable).
- •Inability or unwillingness to give informed consent.
- •Pregnant or nursing females, or females of child-bearing potential who decline a pregnancy test prior to enrollment.
- •Pulmonary hypertension, defined as a right ventricular systolic pressure > 50 mmHg.
- •Individuals with current or recent systematic conditions, such as, acute kidney injury, or conditions that would mandate anticoagulation, such as a recent coronary stent.
- •International Normalized Ratio (INR) < 1.
- •Do Not Resuscitate (DNR) status; Do Not Intubate (DNI) status.
