The muscle thicknesses at this point have also been measured ultrasonographically. The results were evaluated by SPSS statistical software programme. Mann-Whitney U test were used to compare the differences. Eleven of the patients were woman, and 14 of them were men. The distance of this point to the spina iliaca anterior superior obliquely is 9. There was a significant difference between the distance to the sciatic nerve of dorsogluteal and ventrogluteal injection sites while no significant differences were found between the muscle thickness of the ventrogluteal and dorsogluteal injections sites.
This point seems very safe to inject but in emergency cases and in unstable patients small deflections could cause siatic nerve injuries.
It is known that the muscle thickness at the injection side is important for emulsion of the drugs. No statistical difference has been found between the muscle thickness of the ventrogluteal and dorsogluteal injections sites p There are different sites for injection such as thigh, deltoid, dorsogluteal and ventrogluteal site.
All of them have some advantages and disadvantages to each other. For dorsogluteal injections, the sciatic nerve and superior gluteal artery lies very near to the injection site, so great caution should be taken during the procedure.
On the other hand, the ventrogluteal side has a thicker gluteal muscle layer and thinner fat layer and is free of penetrating nerves and blood vessels [4]. Studies have shown that adults with lower BMI and children have a higher risk of injury because of a thinner gluteal fat pad [2]. Especially for this kind of patients, it is better to choose an alternative injection site rather than dorsogluteal point. Also in many guidelines this dorsogluteal site is contraindicated for children.
But traditionally in many settings dorsogluteal site is the first choice to inject. Unintended SC injection is related to difficulty with assessing the thickness of the SC fat pad. Besides altering drug absorption and response, this practice can cause injury to SC tissue. The dorsogluteal fat pad is of inconsistent thickness 1 to 9 cm , whereas the ventrogluteal is more uniform among individuals 3.
Despite these reports' finding that the advantages of the ventrogluteal site have been recognized for almost 45 years, it remains the most infrequently used.
Yet the evidence for its superiority over other sites is compelling, and both author groups of these surveys recommend that it be considered the site of choice for IM injections.
