Summary

This will be a prospective, non-controlled study using healthy adult volunteers as subjects receiving bilateral proximal humerus intraosseous (IO) vascular access to evaluate the insertion technique and IO infusion flow rates.

Detailed description

When using IO access in the perioperative and OR settings, abduction of the arms to the shoulder level prevents use of the traditional proximal humerus insertion site due to the rotation of the humeral head under the acromion process. An alternate proximal humerus IO insertion technique has been developed to meet the needs of anesthesia patient positioning that uses a slightly more distal insertion site and a superior angle of insertion. However infusion flow rate in the proximal humerus using the anesthesia technique has not been measured. This study is needed to evaluate the anesthesia proximal humerus IO insertion technique to determine if the IO infusion flow rates remain unchanged by the alternate method.

Conditions

• Intraosseous Vascular Access

Interventions

Type	Name	Description
DEVICE	intraosseous vascular access in the proximal humerus	The arm receiving the Intraosseous (IO) needle is positioned with the arm abducted to shoulder level (in position required for surgery), with the arm rotated inward, into the optimal position, with the palms faced down. Deeply palpate the humerus until the junction of the humeral shaft and the humeral head, the surgical neck is identified; the insertion site is in the surgical neck. With the 45mm IO needle placed perpendicular to the plane of the skin, the IO needle is inserted into the surgical neck using a slightly superior angle of insertion and the needle is inserted to the hub. The stylet will be removed and a primed EZ-Connect will be attached to the catheter hub.
DEVICE	EZ-IO
