Complications in Spinal Anesthesia

The justification of this chapter is based on knowing the neurological complications that can be triggered during or after spinal anesthesia since it is one of the most performed procedures in anesthesiology, the main objective is to make a chapter with the most described complications in spinal anesthesia. What are the complications of spinal anesthesia? What complications have been described during the procedure or during its postoperative recovery? The spinal anesthesia technique is a necessary procedure to perform a surgical intervention whose objective is to temporarily block the brain’s ability to recognize painful stimuli. Knowing possible complications that can occur during spinal anesthesia or in the postoperative period allows for early diagnosis and treatment. Complications in anesthesia can be clinically manifested by headache, gluteal pain that radiates to the lower limbs, neuropathy, severe paresthesia, among others, and can generate reversible and irreversible disabling lesions depending on their mechanism of injury.
