Point-of-care ultrasound (POCUS) has transformed bedside procedures across emergency medicine, critical care, anesthesia, and hospital medicine. Unlike formal radiology ultrasound (focused, interpreted by radiologists), POCUS is performed by the treating clinician at the bedside to answer specific clinical questions and guide procedures in real time. Evidence consistently demonstrates that ultrasound guidance reduces complications, improves first-attempt success rates, and reduces procedure time across a broad range of clinical applications.
Vascular Access: The Gold Standard Application
Central venous catheter placement under ultrasound guidance: CDC guidelines and nearly all major societies mandate ultrasound guidance for internal jugular CVC placement — reducing arterial puncture from 6.3% to 1.1% in meta-analyses, reducing hematoma formation, and improving first-attempt success. For subclavian and femoral approaches, ultrasound guidance similarly reduces complications. Peripheral IV placement: ultrasound-guided PIVC placement in patients with difficult access ("difficult IV") reduces failed attempts and time to access significantly — studies show first-attempt success rates of 80–90% versus 40–60% for landmark-guided attempts in difficult-access patients. Our vascular access catalog includes ultrasound-compatible needles, catheter kits, and sterile draping supplies for ultrasound-guided procedures.
Additional POCUS Applications With Strong Evidence
Thoracentesis: ultrasound identification of effusion and real-time guidance reduces pneumothorax rate from 4–10% (landmark) to < 1% — Association of American Physicians recommends ultrasound for all therapeutic thoracenteses. Paracentesis: ultrasound reduces bloody tap and bowel perforation rates versus landmark technique. Lumbar puncture: ultrasound improves first-attempt success in obese patients and those with difficult anatomy by identifying interspinous spaces that cannot be palpated. Arthrocentesis (joint aspiration): ultrasound-guided aspiration of shoulder, hip, and ankle joints improves accuracy of needle placement (88–97% vs 72–82% for landmark) and diagnostic yield. Regional anesthesia/nerve blocks: the shift from nerve stimulator to ultrasound-guided nerve blocks has dramatically reduced local anesthetic systemic toxicity and improved block quality. Our diagnostic equipment section includes portable ultrasound-compatible supplies, sterile procedure kits, and drainage supplies for POCUS-guided procedures.
