Vaccination Related Pain: Comparison of Two Injection Techniques

Abstract

The "standard" slow technique was significantly more painful and took longer to administer than the "pragmatic" rapid technique. Cry duration is lesser in pragmaticgroup than standard group, but it is statistically not significant.

Aspirating during the intramuscular injection procedure: a systematic literature review

“…). These findings are supported by Girish and Ravi () and Ipp et al . () who conducted similar RCTs where two injection methods were studied; a slow ‘standard’ technique with aspiration lasting for 5–10 seconds was compared with a faster ‘pragmatic’ technique without aspiration, with the entire procedure lasting only one to two seconds.…”

“…Pain Ipp et al (2006) also reported on respondents who did not aspirate and found that 43% chose not to because they thought it increased pain (Ipp et al 2006). These findings are supported by Girish and Ravi (2014) and Ipp et al (2007) who conducted similar RCTs where two injection methods were studied; a slow 'standard' technique with aspiration lasting for 5-10 seconds was compared with a faster 'pragmatic' technique without aspiration, with the entire procedure lasting only one to two seconds. Findings from both of these studies report that the slower 'standard' process of administration is more painful than the faster 'pragmatic' method.…”

“…Findings from both of these studies report that the slower 'standard' process of administration is more painful than the faster 'pragmatic' method. A limitation of the study by Ipp et al (2007) is the small sample size; however, given that these findings are supported by the more recent study by Girish and Ravi (2014), these findings are considered to be significant. Both of these studies are in the paediatric vaccination setting where the recommended injection sites are the deltoid and vastus lateralis.…”

“…Both within the context of paediatric vaccination, Ipp et al . () and Girish and Ravi () found that a slower injection technique with aspiration was more painful than a faster injection without aspiration. These findings support the previous study by Ipp et al .…”
