Therefore, hypotensive anesthesia is a widely used technique to improve surgical outcomes. This study aimed to compare the efficacy of propofol and dexmedetomidine infusion for hypotensive anesthesia in patients undergoing FESS.Methods: This prospective randomized trial was conducted in 80 adult patients aged between 18 and 50 years who were scheduled for FESS under general anesthesia. Patients were randomly divided into two groups: group P (n = 40) received propofol infusion of 100\u2013200 \u00b5g\/kg\/min and group D (n = 40) received dexmedetomidine infusion with a loading dose of 1 \u00b5g\/kg over 10 min after induction, followed by maintenance infusion of 0.4\u20130.8 \u00b5g\/kg\/h. Intraoperative blood loss, quality of the surgical field (based on the Fromme\u2013Boezaart scale), hemodynamic control, and patient recovery were recorded. Statistical analysis was performed with SPSS software using Student\u2019s t-test, chi-square test, and Mann\u2013Whitney U test.Results: The mean arterial pressure and heart rate were significantly lower in group D throughout the surgery than in group P. Blood loss was significantly higher in group P (100.73 \u00b1 18.12 ml) than in group D (85.70 \u00b1 18.56 ml). The average number of patients with Fromme\u2019s score 1\/2\/3 was comparable between the groups. Intraoperatively, only one incidence of bradycardia and hypotension was observed in group D (2.5%) compared with that in group P, which was insignificant.Conclusions: Both dexmedetomidine and propofol are efficacious and safe drugs for facilitating controlled hypotension during FESS; however, dexmedetomidine provides better hemodynamic control and is associated with lesser blood loss without any significant adverse effects.<\/jats:p>","DOI":"10.17085\/apm.21118","type":"journal-article","created":{"date-parts":[[2022,6,14]],"date-time":"2022-06-14T05:29:06Z","timestamp":1655184546000},"page":"271-279","update-policy":"https:\/\/doi.org\/10.17085\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparative evaluation of propofol versus dexmedetomidine infusion for hypotensive anesthesia during functional endoscopic sinus surgery: a prospective randomized trial"],"prefix":"10.17085","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4140-8099","authenticated-orcid":true,"given":"Kewal Krishan","family":"Gupta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3014-7527","authenticated-orcid":true,"given":"Vandana","family":"Kumari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8685-6840","authenticated-orcid":true,"given":"Sarvjeet","family":"Kaur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7576-2873","authenticated-orcid":true,"given":"Amanjot","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2573","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1985.00800120037003"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-6576.2010.02259.x"},{"key":"ref3","first-page":"109788","volume-title":"The efficacy of Labetalol versus Nitroglycerin for induction of controlled hypotension during sinus endoscopic surgery.
