EMLA and Sterile Water Injections - Pain From Injections

University of Skövde120 enrolled

Overview

The aim is to study the effect of local anaesthesia (EMLA®) on pain associated with sterile water injections.

Sterile Water Injection (SWI) was previously shown to give good pain relief for lower-back pain during childbirth, chronic neck pain and ureterolithiasis. However, the pain associated with the injections remains problematic, and therefore it is important to find a less painful injection technique.
