Ultrasound Guidance for Abdominal Procedures
摘要
Patients undergoing abdominal procedures may benefit from the use of sonographic guidance to increase procedural safety. Ultrasound has improved the safety profile of paracentesis by allowing for the real-time identification of intra-abdominal organs and visualization of the optimal ascites pocket. Gastrostomy tubes, a mechanism for enteral nutrition through an artificial gastric opening, are often placed percutaneously. There is emerging evidence that ultrasound-guidance can assist this procedure through better visualization and reduction of radiation exposure from fluoroscopy. Emerging anecdotal reports suggest that the placement of Blakemore and Minnesota tubes, tamponade devices for hemodynamically unstable patients with hematemesis, can also benefit from ultrasound guidance. Historically, the appropriate placement of the tamponade balloon has been confirmed by X-ray prior to inflation, resulting in a delay in care for a very unstable patient population. There is the possibility that appropriate balloon placement can be more rapidly confirmed by bedside ultrasound and merits further exploration. Ultrasound-guidance represents a rapid, accessible, radiation-free means of improving the safety, accuracy, and efficacy of abdominal procedures.
