Einstiche

Einstiche is a term used primarily in German medical contexts, referring to punctures or puncture sites created by needles during procedures such as injections, blood draws, or catheter insertions. The word derives from einstechen, meaning to stab or pierce with a needle, with Einstich being the noun form for puncture and Einstiche its plural.

In clinical documentation, Einstiche typically denotes the entry points of needles used in a procedure. The related term Einstichstelle denotes a specific puncture site, while Einstiche can refer to the occurrence of multiple puncture events, for example across successive attempts or at different sites during a single encounter.

Clinical significance centers on technique and patient safety. Multiple Einstiche increase the risk of complications such as hematoma, tissue trauma, infection, and nerve or vascular injury. To minimize these risks, clinicians employ proper vein or artery selection, careful needle insertion, sterile technique, and, when appropriate, ultrasound guidance or alternative access methods. Post-procedure care includes monitoring for bleeding, swelling, pain, and signs of infection, and applying appropriate dressings.

Usage and translation: in English-language medical writing, Einstiche are usually translated as puncture sites, venipuncture attempts, or needle sticks. The concept remains tied to the entry points created by needles rather than to the procedure as a whole.
