Non-invasive
Non-invasive (the spelling non-invasive is not Duden-compliant) and minimally invasive are medical terms and refer to procedures in which devices or catheters either do not penetrate the body at all (non-invasive) or to a lesser extent than usual (minimally invasive). Typically, the terms are used to emphasize the minor inconvenience and risk of certain procedures.
Examples:
- In diagnostics , non-invasive methods such as sonography are preferred to invasive methods such as angiography ,
- the non-invasive ventilation ( ventilation without intubation ) is often conventional ventilation (via an endotracheal tube preferred),
- The minimally invasive surgery usually causes less pain and leads to a faster recovery of the patient than conventional surgery.
- the natural vaginal birth offers u. a. advantages over caesarean section in terms of healing process .
The physical examination, simple sonography, the creation of an electrocardiogram and the examination of a urine sample are clearly non-invasive .
Invasive
In contrast, typical invasive measures are operations , punctures and cardiac catheter examinations . Also gastroscopy and blood loss are invasive, but afflicted with low complication rate method. In principle, any invasive measure constitutes bodily harm if the patient has not given his consent.
The assumption that non-invasive or minimally invasive procedures are necessarily to be equated with lower risk is incorrect. Depending on the disease and the patient's condition, for example, not having a cardiac catheter examination can be riskier than performing it, non-invasive ventilation can lead to more complications than conventional and minimally invasive heart valve surgery can lead to worse results than conventional technology.
