Spinal anaesthesia is a procedure that is currently being used a lot because of its benefit to relieve temporary pain sensation in patients without affecting patients' consciousness. However, this action can cause several complications. This study used a descriptive method to determine the complications of spinal anaesthesia based on sex, age, hyperbaric bupivacaine 0.5% drug dose being used, type of surgery, and needle size. The sampling method was total sampling, and the subjects were 57 patients who met the inclusion criteria. The data was taken from the medical records of patients who underwent surgery with spinal anaesthesia. The study showed the complications were headache, nausea, and vomiting, back pain, shivering, and urinary retention. The most common complication was headache which was felt mostly by females (22.58%), age 26-45 (37,61%), the drug dose given was 11-12.5mg (23.65%), and the needle size were 25-gauge (24,73%). The high prevalence of complications experienced by post-surgical patients can be considered an alarm and also highlights the importance of benefiting from skilled personnel and monitoring equipment in this unit.
