[A proposal for a geometrical delimitation model for ventro-gluteal injection].
This study aimed at presenting and comparing geometrical and traditional technique for intramuscular injection in the ventrogluteal area. This is a quasi-experimental study of non-equivalent control group type, carried out with anatomical parts of corpses to verify the precision of function between traditional delimitation using hand as reference and the geometrical model which was constituted by tracing imaginary lines across bone structures of the hip, making a configuration of a triangle whose barycenter points the punction site. The study demonstrated that the punction site delimited by the geometrical technique keeped proportion of the envolved structures, and matched with the muscular womb of the ventrogluteal area in 100% of punctions. In another hand, in the traditional technique the punction site varied in 39.9% of punctions.
