Saline solution is a sterile mixture of sodium chloride (salt) and water, commonly used in veterinary medicine for horses. It serves various purposes, including rehydration, electrolyte balance restoration, and as a vehicle for administering medications. In equine care, saline solution can be administered intravenously, subcutaneously, or as a lavage to cleanse wounds. Its isotonic nature makes it compatible with equine blood and tissues, minimizing the risk of adverse reactions. This page compiles peer-reviewed research studies and scholarly articles that explore the applications, administration methods, and physiological effects of saline solution in equine health management.
De Castilho T, Rosa GDS, Stievani FC, Apolônio EVP, Pfeifer JPH, Altheman VG, Palialogo V, Santos NJD, Fonseca-Alves CE, Alves ALG.Tendinopathies account for a substantial proportion of musculoskeletal injuries. To improve treatment outcomes for partial and total tendon ruptures, new therapies are under investigation. These include the application of mesenchymal stem cells (MSCs) and biocompatible scaffolds derived from the Extracellular Matrix (ECM). Synthetic polymer hydrogels have not demonstrated results as promising as those achieved with ECM hydrogels sourced from the original tissue. This study aimed to evaluate the biocompatibility of a hydrogel formulated from equine tendon ECM. Six horses were administered three...
Dos Santos GC, Di Filippo PA, da Fonseca LA, Quirino CR.The purpose of this study was to compare the extent of inflammation response in the middle carpal joints of healthy horses following intra-articular injection of 2% lidocaine, 0.5% bupivacaine, or 0.9% saline solution. The right middle carpal joint of 20 horses was injected with 5 mL of 0.5% bupivacaine (GB, n = 10) or 5 mL of 2% lidocaine (GL, n = 10). The left middle carpal joint of horses was used as a control (5 mL 0.9% saline). Serum and synovial fluid (SF) were aseptically collected before and at predetermined times after each injection. Serum and synovial fluid protein, albumin, tra...
Enke N, Brinkmann L, Südekum KH, Tholen E, Gerken M.Horses lose high amounts of Na through excessive sweating. These fluid losses can often not be replaced completely by voluntary water intake, requiring saline solutions as rehydration therapy to regain electrolyte balance. The experiment aimed to evaluate the sensitivity and tolerance of Shetland ponies towards different Na concentrations in their drinking water and contained three phases: (1) control: only fresh water provided; (2) pairwise-preference test: choice between fresh water and saline solution with stepwise increasing sodium chloride (NaCl) concentration (0.25%, 0.5%, 0.75%, 1.0%, 1...
Brilhante RS, Bittencourt PV, Castelo-Branco Dde S, de Oliveira JS, Alencar LP, Cordeiro Rde A, Pinheiro M, Nogueira-Filho EF, Pereira-Neto Wde A....This was a cross-sectional study to investigate the antifungal susceptibility and production of virulence factors in strains of Candida isolated from the outlet and the lumen of the nasolacrimal duct of horses in the state of Ceará, Brazil. The samples were obtained from 103 horses. Sterile cotton swabs were used to collect the material from the outlet of the nasolacrimal duct and urethral probes, for the instillation of 2 ml of saline solution, were used to collect samples from the lumen of the nasolacrimal duct. A total of 77 Candida isolates were obtained, with C. famata, C. tropicalis, C....
Crovace A, Lacitignola L, Rossi G, Francioso E.The aim of this study was to compare treatment with cultured bone marrow stromal cells (cBMSCs), bone marrow Mononucleated Cells (BMMNCs), and placebo to repair collagenase-induced tendinitis in horses. In six adult Standardbred horses, 4000 IU of collagenase were injected in the superficial digital flexor tendon (SDFT). Three weeks after collagenase treatment, an average of either 5.5 x 10(6) cBMSCs or 1.2 x 10(8) BMMNCs, fibrin glue, and saline solution was injected intralesionally in random order. In cBMSC- and BMMNCS-treated tendons, a high expression of cartilage oligomeric matrix protein...

Hypercalcemia was induced for 2 hours. Dextrose, sodium gluconate, and saline solution were infused for 2 ...
Carregaro AB, Neto FJ, Beier SL, Luna SP.To investigate the effects of buprenorphine on cardiopulmonary variables and on abdominal auscultation scores in horses. Methods: 6 healthy adult horses. Methods: Horses were restrained in stocks and allocated to 2 treatments in a randomized crossover design, with 1-week intervals between each treatment. Saline (0.9% NaCl) solution was administered IV as a control, whereas buprenorphine (10 mug/kg, IV) was administered to the experimental group. Cardiopulmonary data were collected for 120 minutes after buprenorphine or saline solution administration. Abdominal auscultation scores were monitore...
Xie H, Colahan P, Ott EA.To evaluate use of electroacupuncture for treatment of horses with signs of chronic thoracolumbar pain. Methods: Prospective study. Methods: 15 horses with signs of chronic thoracolumbar pain. Methods: Horses were randomly allocated to 1 of 3 treatment groups. Horses in group 1 received electroacupuncture stimulation (once every 3 days for 5 treatments), those in group 2 received phenylbutazone (2.2 mg/kg [1 mg/lb], PO, q 12 h, for 5 days), and those in group 3 received saline (0.9% NaCl) solution (20 mL, PO, q 12 h, for 5 days). Thoracolumbar pain scores (TPSs) were evaluated before (baseline...
Herschl MA, Trim CM, Mahaffey EA.Twelve horses of various breeds and either sex were anesthetized with xylazine and ketamine injected into a median or lateral thoracic vein. During anesthesia, with the horse in sternal recumbency, a 14-gauge, 8.9 cm catheter was inserted into each jugular vein by using aseptic technique. Guaifenesin in water (100 mg/kg or a maximum dose of 50 grams) was infused into one jugular vein and an equal volume of 0.9% saline solution was infused into the other jugular vein. Seven horses received 10% guaifenesin, and five horses received 5% guaifenesin. The catheters were removed before the horses rec...
Pascoe DR, Stabenfeldt GH, Hughes JP, Kindahl H.Thirty mares with normal estrous cycles were allotted equally to 5 groups and infused with 250 ml of saline (NaCl) solution in utero on the seventh day after ovulation to test the effects of temperature, osmolarity, or pH of the saline solution on prostaglandin F2 alpha (PGF2 alpha) release and luteolysis. Intrauterine infusion of phosphate-buffered saline solution failed to alter the duration of the luteal phase, compared with the control group. Similarly, increasing the temperature of phosphate-buffered saline solution to 42 C or increasing (600 mosm) or decreasing osmolarity (less than 10 m...
Adams GP, Ginther OJ.We evaluated the efficacy of intrauterine plasma infusion in mares as a treatment for infertility caused by endometritis and distinguished the effects of intrauterine infusion of plasma vs saline solution. Forty-three subfertile mares were randomly assigned to 1 of 3 treatment groups: untreated controls (n = 14), those treated by saline infusion (n = 14), and those treated by plasma infusion (n = 15). Reproductive status was assessed daily by transrectal ultrasonography. Uterine aspirates and biopsy specimens were obtained 8 days after ovulation for cytologic and histologic evaluation, and mar...
Wagner AE, McIlwraith CW, Martin GS.Orgotein was injected into the right intercarpal joint of each of 8 horses; the corresponding left joint was left alone (not injected) or was given an injection of normal saline solution. Injection with orgotein caused a transient, marked inflammatory response, evidenced by clinical signs and by increased leukocytes and total protein in the synovia (synovial fluid). Leukocyte numbers and total protein concentration were increased (P less than 0.010) in the orgotein-injected joints within 24 hours. However, saline solution alone also elicited a marked inflammatory response, manifested by increa...
Neely DP, Stabenfeldt GH, Kindahl H, Hughes JP, Kendrick JW.The intrauterine infusion of 500 ml of warm sterile saline solution into mares on days 12, 13, or 14 after ovulation failed to alter the ovulatory interval, although intervals were shorter for days 12 and 13 (20.6 days) when compared with those in control mares (21.6 days). The IU fusion shortened luteal-life-span on days 12 (12.0 vs 13.8 days) and 13 (13.0 vs 14.4 days) (P is less than 0.05), but not day 14 (14.0 vs 13.5 days), when comparing the effects of IU infusion with an average of before and after base-line data. There was no effect on the interval from corpus luteum regression to ovul...
