SonoSite SII

The SonoSite SII ultrasound machine is designed for use in multiple clinical areas, but is especially well suited to Anesthesiology, Vascular Access, and Trauma uses. 

Regional Anesthesiologists have enthusiastically embraced the SonoSite SII for help visualizing nerves and vascular anatomy while placing regional nerve blocks.

Enhanced image quality and touchscreen controls, combined with nerve exam presets for rapid scanning, make the SII an excellent choice for anesthesiologists who wish to provide the best perioperative pain management. 

The SII is also easy to clean, making it the perfect choice for operating rooms in which infection control is an absolute must. The durable glass screen covers the full face of the SII, and can be disinfected. Touchscreen controls can be simply disabled before cleaning to avoid accidental activation of the machine while disinfecting.

For post-operative analgesia, the interscalene block is favored by anesthesia specialists. The SII provides clear visualization of the needle and nerve during block placement, allowing precise placement of local anesthetic with minimal patient discomfort. 

For anesthesiologists, managing patient volume status is crucial to positive outcomes. The SII’s clear visualization of the IVC, heart and lungs enable anesthesiologists to quickly assess cardiac output, diagnose pulmonary edema and determine a patient’s volume status.

Thoracic wall blocks such as the Pecs I & II are becoming increasingly popular among anesthesiologists who wish to avoid the risks associated with paravertebral blocks, while striving to provide exceptional post-operative pain management to patients undergoing breast surgery. The SII offers clear visualization of the major and minor pectoral muscles, as well as the pleura and vulnerable vascular structures. The SII’s steep needle profiling helps guide the needle tip for accurate local anesthetic placement.

SII is a preferred machine for ultrasound-guided vascular access. The SII’s clear imaging and simple controls allow clinicians to simply and quickly adjust depth and gain settings to locate accessible locations for guided venipuncture and arterial access. Reduced speckle and enhanced contrast provide strikingly clear images of vascular pathways. 

On patients with challenging vascular conditions, the SII can offer ultrasound guidance for peripheral IV (PIV) placement, often mitigating the need for central venous catheter placement in patients whose venous access is otherwise impeded.  

For critically ill patients (and for those patients for whom a peripheral IV is not possible), the SII is often used for ultrasound-guided CVC placement, drastically reducing the instance of pneumothorax (as opposed to the landmark method). 

Both Color Doppler and Color Power Doppler modes are available on the SII. Visualize the presence and direction of blood flow in a wide range of flow states. 

The SII’s Center Line Guide provides onscreen visual guidelines to help determine the location of vascular pathways during live scans.

For busy trauma bays, the SII offers an outstanding physical design (zero footprint when mounted on an attenuating arm; very small footprint when used with optional stand). With two built-in transducer connections, trauma specialists can rapidly go from eFAST exam (P19 transducer) to ultrasound-guided central venous catheter placement (with the L25 transducer). The easy-to-clean system also gets approval from infection-control advocates.

The SII provides the following calculations for cardiac exams: 

• Ejection fraction
• Volume measurements
• Simpson’s rule
• IVC Collapse Ratio
• LA/RA Volume
• TAPSE 

The SII allows you to view ejection fraction and fractional shortening calculations simultaneously.
