Effects of Preoperative Coffee Consumption in Cesarean Sections Under Spinal Anesthesia

Study Overview
=================
Brief Summary
-----------------
The prospective study is planned in a university hospital. Spinal anesthesia is widely used for cesarean section currently for its safety, low cost, reliability, easiness to administer, immediate effect, and well-operating conditions. However spinal anesthesia has some complications as hypotension, bradycardia and Post Dural Puncture Headache (PDPH). A practical strategy for avoiding hypotension during initiation of spinal anesthesia for cesarean delivery includes intravenous crystalloid, in conjunction with administration of vasopressors. PDPH is one of the most frequent complications of spinal anesthesia. Conservative therapies such as bed rest, hydration, and caffeine are commonly used as management. For this study, coffee group of patients will be given unsweetened brewed coffee 150 ml until 2-4 hours before surgery. Patients who accept to drink brewed coffee ( coffee group) and water( control group) will be included in the study. The patient's heart rate, blood pressure, oxygen saturation will be monitored and recorded during operation. Intraoperative will be recorded to amount of vasopressor and intraveous crystalloid. Whether the patient develops PDPH in the postoperative period will be followed for 3 days. In addition abdominal auscultation for bowel sounds hourly and the time of first bowel movements will be recorded. According to the patient's statement, the time of first flatulence and defecation will be followed and recorded.
