Patients were randomly allocated into two groups: Group A received 22.5 mg of 0.75% hyperbaric ropivacaine, and Group B received 15 mg of 0.5% hyperbaric levobupivacaine intrathecally. Parameters studied included onset and duration of sensory and motor block, regression times, hemodynamic changes, duration of analgesia, and adverse effects.

Levobupivacaine offers a rapid onset, prolonged duration of sensory and motor block, and better hemodynamic stability, whereas ropivacaine ensures quicker recovery but with shorter analgesia and a higher incidence of adverse effects. The choice of drug should be tailored to surgical requirements and patient profile.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/aam.aam_741_25","type":"journal-article","created":{"date-parts":[[2026,4,8]],"date-time":"2026-04-08T06:00:13Z","timestamp":1775628013000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Hyperbaric Ropivacaine and Hyperbaric Levobupivacaine in Lower Limb Orthopedic Surgery under Subarachnoid Block: A Prospective Randomized Controlled Trial"],"prefix":"10.4103","author":[{"given":"Monica","family":"Verma","sequence":"first","affiliation":[{"name":"Department of Anesthesiology- Intensive Care, Ranchi, Jharkhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramesh Kumar","family":"Kharwar","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology- Intensive Care, Ranchi, Jharkhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tushar","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology- Trauma RIMS, Ranchi, Jharkhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekramul","family":"Haque","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology- Intensive Care, Ranchi, Jharkhand, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,4,8]]},"container-title":["Annals of African Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/aam.aam_741_25","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T15:45:18Z","timestamp":1787067918000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/aam.aam_741_25"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.4103\/aam.aam_741_25","relation":{},"ISSN":["1596-3519","0975-5764"],"issn-type":[{"value":"1596-3519","type":"print"},{"value":"0975-5764","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,8]]},"assertion":[{"value":"2025-11-17","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-04","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
