The Effect of Hydration and Caffeine on Post-Spinal Anesthesia Headache: A Randomized Controlled Study

Objective: Evaluate the effects of hydration and caffeine, administered of patients who received spinal anesthesia, on postspinal headache. Methods: Randomized controlled experimental study. The study was carried out in the post-anesthesia care unit and surgery clinics of a City Hospital between November and December 2014. The sample composed of 90 patients who received spinal anesthesia. The patients were assigned into 3 groups based on the order of leaving the operating room by using a randomization check list. Percentage and chi-square test were used to assess the data. Results: It was found that 23.3% of the patients in the first group (receiving 3000 cc intravenous fluid), 20.0% of the patients in the second group (Intravenous 3000 ml fluid + 75 mg (4 cups) oral caffeine), and 13.3% of the patients in the third group (Intravenous 4000 ml fluid) had headaches. Post-Spinal Anesthesia Headache was similar between the groups. But, it was determined that number of the patients with headache in third group was lower. Most of the patients in all three groups specified that their headaches reduced by resting, increased by standing up, did not cover their nucha and shoulder, and increased by movement. Conclusion: It is concluded that although there was no statistical significance, rate of headache in the hydration group (Third group) was lower than the other groups. Also it was determined that administration of excess fluid after spinal anesthesia reduced the level of post-spinal headache but it could not prevent its development
