Bacteriological control of milk and effectiveness of antimastitis measures in cows

Under the current conditions of livestock development, the main task of farms is the systematic bacteriological control of milk and the development of comprehensive programs for the control and prevention of mastitis in cows. These measures will make it possible to establish control over this pathology, reduce veterinary treatment costs, improve milk quality, increase average hopes for lactation, increase the productive use of cows, and more. It was found that among the forms of clinical mastitis in the farm registered catarrhal and purulent-catarrhal (65.0 %), serous (12.0 %), and less often – fibrinous (11.5 %), hemorrhagic (11.0 %), and abscess udder (0.5 %). Bacteriological studies of milk taken from cows proved the presence of Staphylococcus saprophyticus, Escherichia coli, β-hemolytic Streptococcus spp. Microbiological studies showed that the isolated cultures of microorganisms were sensitive to tetracycline, neomycin, and cloxacycline; conditionally sensitive to streptomycin, doxycillin; no sensitivity to amoxicillin + clavulanic acid, norfloxacin and gatifloxacin. A treatment scheme was proposed for patients with purulent-catarrhal mastitis of cows, included intra-tank injections of the drug “Mastidev-Linko,” intramuscular injections of the drug “Tseftiodev 5%” and external application of the ointment “Dibutaliastin.” As a result of studies on the therapeutic efficiency of the proposed veterinary drugs when used in cows of Holstein-Friesian and black-spotted breed, patients with purulent-catarrhal mastitis, 91.6 % therapeutic efficiency of drugs was established. It is recommended that animals infected with infectious agents should be milked last and milking machines thoroughly disinfected; apply the pre- and post-milking treatment of udder teats with disinfectants (dips); periodically check in the laboratory the disinfecting ability of drugs for udder treatment and disinfection of accessories; use only proven tools; control the correct preparation of solutions and treatment of the udder with disinfectants (dips); to reject animals that do not respond to treatment (chronically ill).

NURSING PRACTICES IN PERIPHERAL VENOUS CATHETER: PHLEBITIS AND PATIENT SAFETY

ABSTRACT Objective: to understand the nursing practices related to peripheral venous catheter and to identify deviations related to the scientific evidence regarding the prevention of phlebitis. Method: qualitative study with data collection by means of participant observation techniques and semi-structured interviews, with 26 and 15 nurses, respectively, from a Portuguese hospital. Data content analysis was performed. Results: In the category “nursing actions”, nursing practices related to: selection of catheter insertion site and its caliber size, evaluation of insertion site for signs of inflammation, insertion site dressing, disinfection of accessories, hand hygiene and patient participation in care emerged. There were situations of deviations in these practices in relation to scientific evidence. Conclusion: Nursing practices presented deviations in relation to scientific evidence, and were influenced by the size of the institution, patient characteristics, and lack of knowledge of nurses regarding certain actions that pose a risk to patient safety. The creation of protocols and the implementation of continuous education are fundamental for the acquisition of competencies by nurses, for correcting deviations and providing a safe quality nursing care to the patient.
