Proposta de um modelo de delimitação geométrica para a injeção ventro-glútea

Abstract

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.

Intramuscular injection safety without aspiration in the ventro-gluteal region during vaccination: randomized clinical trial

“…Participants and team members who performed AEFI assessment and statistical analysis did not know which group participants belonged to, nor did the researcher who performed the intervention not witness the AEFI assessment. The VG region site was performed according to the geometric delimitation method, which consists of drawing imaginary lines between the antero-superior iliac crest, the posterior margin of the iliac tubercle and the greater trochanter of the femur, whose union of the vertices will form a triangle and its barycenter indicates the puncture site (8) .…”

“…During the administration of medications in the ventrogluteal region, angulation of 90°1 [3][4][5][6][7][8][9][10][11][12][13][14] should be used, however, it was verified that the insertion of the needle could be at any angle allowing risks for an iatrogenic event due to puncture site distortion, this delimitation does not always keep proportional relations between the hand of the person applying the injection and the size of the patient's hip. 15…”
