Post-operative nausea and vomiting (PONV) in women undergoing subarachnoid anesthesia for Caesarean section is an important clinical problem. Known mechanisms underlying PONV are based on prolonged fasting, hypotension due to concomitant sympatholysis during anesthesia, bradycardia due to increased vagal tone, visceral stimulation during surgery and intrathecal administered opioids. However, the identification of patients exposed to this problem and appropriate perioperative preparation is of key importance. An analysis of risk factors for postoperative nausea and vomiting in patients undergoing elective cesarean section under spinal anesthesia is of major clinical importance. The aim of this study is a comparison of the effectiveness of oral carbohydrate loading strategy as compared with standard pre-operative fasting in patients undergoing elective cesarean section under spinal anesthesia on the incidence and severity of PONV and biochemical parameters indicating ketosis.
