Administering equivolume, equiosmolar solutions in healthy animals could help produce fundamental data on water translocation in uninjured tissue. Furthermore, the role of furosemide as an adjunct to osmotherapy remains unclear.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Two hundred twenty isoflurane-anesthetized rats were assigned randomly to receive equivolume normal saline, 4.2% HS (1,368 mOsm\/L 25% mannitol (1,375 mOsm\/L), normal saline plus furosemide (8 mg\/kg), or 4.2% HS plus furosemide (8 mg\/kg) over 45 min. Rats were killed at 1, 2, 3, and 5 h after completion of the primary infusion. Outcome measurements included body weight; urinary output; serum and urinary osmolarity and electrolytes; and brain, lung, skeletal muscle, and small bowel water content.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n In the mannitol group, the mean water content of brain tissue during the experiment was 78.0% (99.3% CI, 77.9\u201378.2%), compared to results from the normal saline (79.3% [99.3% CI, 79.1\u201379.5%]) and HS (78.8% [99.3% CI, 78.6\u201378.9%]) groups (P<\/jats:italic> < 0.001), whereas HS plus furosemide yielded 78.0% (99.3% CI, 77.8\u201378.2%) (P<\/jats:italic> = 0.917). After reaching a nadir at 1 h, brain water content increased at similar rates for mannitol (0.27%\/h [99.3% CI, 0.14\u20130.40%\/h]) and HS (0.27%\/h [99.3% CI, 0.17\u20130.37%\/h]) groups (P<\/jats:italic> = 0.968).<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n When compared to equivolume, equiosmolar administration of HS, mannitol reduced brain water content to a greater extent over the entire course of the 5-h experiment. When furosemide was added to HS, the brain-dehydrating effect could not be distinguished from that of mannitol.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/aln.0b013e31828156ff","type":"journal-article","created":{"date-parts":[[2013,1,9]],"date-time":"2013-01-09T18:01:37Z","timestamp":1357754497000},"page":"903-913","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":23,"title":["Comparison of Equivolume, Equiosmolar Solutions of Mannitol and Hypertonic Saline with or without Furosemide on Brain Water Content in Normal Rats"],"prefix":"10.1097","volume":"118","author":[{"given":"Liang Chao","family":"Wang","sequence":"first","affiliation":[{"name":"Assistant Professor, Department of Surgery, College of Medicine, National Cheng Kung University, Tainan, Taiwan, Republic of China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Papangelou","sequence":"additional","affiliation":[{"name":"Assistant Professor, Department of Anesthesiology and Critical Care Medicine and Department of Neurology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Lin","sequence":"additional","affiliation":[{"name":"Research Assistant"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marek A.","family":"Mirski","sequence":"additional","affiliation":[{"name":"Professor"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Allan","family":"Gottschalk","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Anes thesiology and Critical Care Medicine, Department of Neurology, and Department of Neurosurgery, The Johns Hopkins University School of Medicine, Baltimore, Maryland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas J.
