Method for Optimal Tract Anesthesia During Biopsies, Drainage Catheter Placement, Nephrostomies, and Percutaneous Transhepatic Cholangiography

Transrectal and transvaginal approaches for abscess drainage can be safer than other approaches but may cause greater patient discomfort at the time of placement. Achieving optimal anesthesia can be difficult in certain situations, particularly when using a transvaginal or transrectal approach. By using a side port adapter and a high-quality 3-cc syringe, operators can provide additional anesthetic while using the Seldinger technique. This method allows for additional anesthetic to be placed in the vaginal cuff, thus allowing a greater number of transvaginal procedures to be performed with moderate sedation as opposed to general anesthesia. The technique can also be applied to other percutaneous procedures, such as nephrostomy tube placement.
