Because ultrasound sound waves have a difficult time traveling through the air, ultrasound gel is used to reduce the air between your patient and the transducer to reduce acoustic impedance and reflection to allow for a clear image to be produced.
Ultrasound medical gel composition, the compositions comprising: (a) a gelling agent comprising etherified hydroxyethylcellulose; (b) an antimicrobial agent, specifically the quaternary ammonium compound benzalkonium chloride; (c) a solvent, 1,3-propanediol being preferred; and (d) water.
Results show that KY- Jelly used as coupling medium in ultrasonography produced a better image than of the standard ultrasound coupling gel and it can be considered as an alternative to the standard ultrasound coupling gel.
after the procedure remove all residual gel from the patient's skin and advise patients to wash area when feasible.
