Insertion of midline catheters in critically ill patients with limb trauma and fractures: Feasibility and case report.

This article reports a critically ill patient with extremity fractures caused by a traffic accident. Given the severity of the patient's condition and the specific nature of the fractures, after a thorough evaluation of the fracture sites, a midline catheter was placed in the affected side's upper arm through ultrasound guidance as a vascular access solution. The catheter was safely retained for 63 days, completing the entire treatment cycle without any related complications, providing stable and reliable vascular access support for the patient's overall treatment. This case demonstrates the feasibility of using midline catheters in critically ill patients with extremity fractures, offering new perspectives and references for the selection of vascular access in these patients.
