Background　Continuous spinal anesthesia(CSA) is an efficient sub-arachnoid anesthesia with rapid onset, stable anesthetic effects, and the ability to adjust the dosage of anesthetics. As this technique provides stable hemodynamics and ideal controllability, it has been used for major obstetric and gynecological crisis with complications of heart and pulmonary diseases. However, its clinical applications have been hindered by its common complications, including post-dural puncture headache(PDPH).　Objective　To review clinical applications of CSA in obstetric anesthesia to gain insight to improve CSA in obstetric anesthesia.　Contend　In obstetrics, CSA assures seamless opportunity to transit vaginal birth to cesarean section. As CSA provides fast induction of anesthesia, stable hemodynamics, and controllability to administer appropriate doses of anesthetics, it has minimal effects on fetus, and has been applied to cesarean section in pregnant women with pregnancy-related hypertension and thrombocytopenia, heart and pulmonary diseases, and scoliosis. With supreme anesthetic efficacy, CSA has nonnegligible complications, such as, post-dural puncture headache(9%-29%), cauda equina syndrome, unsuccessful anesthesia, and brief aphasia, etc.　Trend　Despite the nonnegligible complications, advantages of CSA entitle it as a versatile technique for obstetric anesthesia with supreme efficacy and wide-range of indications.
