Einstichstelle

Einstichstelle is a German term that denotes the point of entry where a needle, cannula, or other instrument enters the body or a tissue. In medical practice it is used to describe the puncture site left after procedures such as venipuncture (blood sampling), injections (subcutaneous, intramuscular, or intravenous), peripheral IV catheter placement, biopsy, or drainage.

The site is typically prepared with an antiseptic and, when appropriate, locally anesthetized before insertion. After the procedure, a sterile dressing is applied and the site is advised to be kept clean and dry. Depending on the procedure, the dressing may be removed after a few hours to a day, and patients are often instructed to monitor the area for changes.

Care and healing considerations include keeping the area free from trauma, avoiding prolonged immersion, and watching for signs of infection or complications. Normal findings in the days after can include mild redness or tenderness at the puncture tract, which should gradually resolve.

Possible complications associated with an Einstichstelle are infection, localized bleeding, hematoma, bruising, swelling, pain, or irritation. Rarely, injury to underlying nerves or vessels can occur, or issues such as catheter-related problems or leakage from the entry point may arise. If swelling increases, fever develops, the area becomes increasingly red or painful, or pus is observed, medical evaluation is advised.

In medical records the Einstichstelle is documented with its location, side, the device used, and any related complications. Forensic or clinical assessments may reference the appearance and healing status of the puncture site.
