      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Other design features: In women undergoing elective cesarean section, postural puncture headache indices were compared between the two groups for the effect of fluid therapy before spinal anesthesia, Randomization description: Participants in this study were divided into control and intervention groups using simple randomization (random number tables), Blinding description: The population of the study was two groups of women. One group received 500 cc Ringer serum before entering the operating room and the other group did not receive this serum. Patients in our study were aware of serum intake but were unaware of the purpose of serum therapy.</study_design>

      <i_freetext>Intervention 1: Intervention group: each containing 75 candidates for elective cesarean section. After a minimum fasting period, women received 500 cc of Ringer serum one hour before the start of the spinal block. The incidence, severity and duration of their headache were evaluated. Intervention 2: Control group: women were admitted to the operating room with a minimum of eight hours of fasting in the morning and received no serum.</i_freetext>
