Crystalloid preload versus crystalloid coload during spinal anesthesia for ureterorenoscopy: A randomized controlled trial
Abstract
Aim: The optimal strategy of fluid administration during spinal anesthesia is still unclear. In this
double-blind randomized study, we assessed the timing of fluid administration for spinal anesthesia in
patients undergoing ureterorenoscopy.
Materials and Methods: 60 ASA I-III patients scheduled for anesthesia were randomly allocated to
receive either 500 ml crystalloid preload (30 minutes before spinal anesthesia) or 500 ml crystalloid
coload (at the start of spinal anesthesia). Ephedrine 5 mg boluses were administered when the
systolic blood pressure decreased more than 20% of the baseline value. Atropine 0.5 mg was given to
the patients whose heart rate decreased bellow 50 beats/minutes. Hemodynamic variables were
recorded during the surgery.
Results: The groups were compared in terms of demographic data and surgical time and there was
no difference between them. In Group II, only 1 patient needed ephedrine, while in Group I, no patient
was administered ephedrine. No patients in both groups needed atropine for bradycardia. There was
no difference between the groups in terms of the need for ephedrine.
Conclusion: Crystalloid preload and crystalloid coload administration do not differ in terms of the need
for vasopressor agents in patients undergoing ureterorenoscopy under spinal anesthesia
