Üreterorenoskopi için spinal anestezi sırasında kristalloid preloada karşı kristalloid koload: Randomize kontrollü çalışma

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
