Comparison between hydroxyethyl starch and ringers lactate preloading solutions in elective inguinal hernia repair under subarachnoid block anesthesia

Abstract EN

Objective : to compare the influence of two intravenous fluids on blood pressure and heart rate modifications after subarachnoid block anesthesia in inguinal hernia repair.

Methods : the study included 100 patients, of both sexes, aged 32-64 years, classed I-II by the American society of anesthesiologists and scheduled for elective inguinal hernia repair at Prince Rashid hospital, Irbid, Jordan ,during the period April 2014-April 2015.Participants were divided in a random manner into two groups.

Group I (n=50), patients received Ringers lactate solution (500 ml) .Group II (n=50), patients received Voluven (500 ml) as preloading before subarachnoid block anesthesia.

Requirement of ephedrine was compared between the groups.

Blood pressure and heart rate were compared between the groups.

Results : there was no discrepancy in the basic blood pressure and heart rate recordings between the groups.

The frequency of hypotension and needed ephedrine was less in Voluven group (P<0.05) (stastically significant) than in Ringers lactate group.

Conclusion : preloading with Voluven is more efficient than Ringers lactate solution in avoiding hypotension following subarachnoid block anesthesia.
