Hemodynamic response to venous cannulation in differently timed EMLA cream application in childrena prospective comparative study

Dr Shamim Kunhu. V, Dr Sheela Verghese

Abstract :

Background

Venous access is the most commonly performed invasive procedures in a health care set up. Needle prick does hurt and results in distress and anxiety.Most of the time this adverse response is underestimated and untreated. Fear of the procedure can trigger an autonomic response causing change in heart rate and blood pressure and vasoconstriction.The hemodynamic response to venous cannulation can adversely affect children with cardiac illness.

MATERIAL AND METHODS–

The heart and blood pressure during venous cannulation were compared in seventy five patients. Haemodynamic variables were noted in patients with no EMLA,EMLA applied 30 minutes, and 60 minutes prior to venous cannulation. The change in haemodyanamic variables before and after cannulation were studied.

RESUTLS –

Statistically significant variation in heart rate,systolic blood pressure were noted between the three groups. The lowest change in heart rate and systolic blood pressure was observed in 60 minute EMLA group,followed by 30 minutes group and highest change being in no EMLA group.

CONCLUSION� though there were a statistically significant difference noted in the haemodynamics between the groups with or without EMLA ,it failed to reach any clinically relevant significance.
