The common sequelae of lumbar anesthesia are as follows: 1, headache: caused by extravasation of cerebrospinal fluid after anesthesia, 6 hours of postoperative lying on the pillow can effectively reduce and alleviate postoperative headache after lumbar anesthesia; 2, nausea, vomiting: severe cases can be treated with symptomatic nausea and vomiting drugs; 3, pain at the puncture site: puncture-induced injury, such as local ligament and periosteal injury, can cause local pain in the lumbar region; 4, urinary retention: 6 hours after lumbar anesthesia For 6 hours after lumbar anesthesia, drinking water is prohibited to prevent urinary retention from occurring. In a word, the sequelae of lumbar anesthesia include postoperative nausea, vomiting, headache, lumbar pain, abnormal limb movement, nerve damage, and even paraplegia, but the chances of sequelae after general lumbar anesthesia are small.
