GOALS: The aim of this study is to compare the efficacy of HES 130/0.4, a new hydroxyethyl starch, to lactated Ringer's solution (LR) in the prevention of hypotension after spinal anesthesia for cesarean section (CS). MATERIAL AND METHODS: One hundred and twenty nonlaboring ASAI and II women having non urgent CS were enrolled in this prospective and randomized study. Subjects were randomly assigned to receive prior to anesthesia either 1 liter of LR (Gr I: n = 59) or 500 ml of HES 130/0.4 (Gr II : n = 61). Blood pressure was measured until discharge from the post anesthesia care unit. Hypotension was treated with i.v. boluses of 3 mg of ephedrine. The nausea scale was recorded. Arterial and venous umbilical blood gazes were obtained. Data were compared using Mann-Whitney U-test and Student's t-test (p < 0.05 was significant). RESULTS:Thirty-nine patients in Gr II while 48 pts in Gr I experienced hypotension (p = .033). The total dose of ephedrine was statistically smaller in Gr II compared with Gr I (p = .001). Nausea after induction of spinal anesthesia occurred with similar frequency in both groups. Neonatal outcome was excellent and similar in both groups. CONCLUSION:HES 130/0.4 is more effective than LR to prevent hypotension following spinal anesthesia for CS; its routine use in this purpose should be considered.
