Factors associated with phlebitis in peripheral venous catheters of hospitalized patients
(Universidad Privada Norbert Wiener, 2017-03-02) Condori Báez, María Belén; Contreras Rojas, Eva Gisela; Calsin Pacompia, Wilmer
Method: Systematic review, and the population constituted by the bibliographic review of 9 scientific articles published and indexed in scientific databases and that respond to articles published in Spanish, Portuguese and English. Results: The factors associated with phlebitis that were found are the age, weight of the patient, medication that is being infused (drugs with extreme pH and osmolarity solutions), type of infusion and infused solutions, the speed of infusion (using infusion pump ) the quality of infection prevention practices, the length of time the catheter remains in place (no more than five days), caliber of the catheter (the smaller the caliber, the lower the risk of phlebitis), the size of the catheter, the location of insertion, the lack of catheter management protocol, in addition to the time at which the peripheral catheter is placed (day/night shift), having a greater risk of phlebitis on the night shift. Conclusions: According to all the articles reviewed, it is concluded that the factors associated with phlebitis were: the most common was type of medication according to its pH, osmolarity, followed by the place of insertion of the peripheral catheter, length of stay and finally it was considered as a factor. of risk the infusion time of the medication to be infused.

Urinary Osmolality and Its Relationship with Glomerular Filtration Rate. Laboratory of the National Hospital Hipólito Unánue. Lima 2016
(Universidad Privada Norbert Wiener, 1905-07-09) Cruzado Avila, Ivette Johalina; Sandoval Vegas, Miguel Hernán
The objective of the study was to determine urinary osmolality and its relationship with glomerular filtration rate (GFR) using the CKD-EPI and MDRD-4 formulas in patients treated at the National Hipólito Unanue Hospital laboratory in Lima, 2016. A total of 184 urine samples meeting the inclusion criteria were selected, with 24-hour urinary osmolality measured and GFR data processed from the hospital laboratory using the Dubois and Dubois body surface area (BSA) formula. GFR was also calculated using the Mosteller and Boyd BSA formulas and the MDRD-4. Results were analyzed using Pearson’s r and Student’s t-test. No correlation was found between GFR or MDRD-4 with urinary osmolality at any stage of chronic kidney disease. A significant difference in osmolality values was observed between stage 1 (GFR >60 mL/min) and the other stages of chronic kidney disease (GFR <60 mL/min). Thus, there was no correlation between osmolality and GFR, but urinary osmolality can be used as an indicator to classify patients with adequate or decreased glomerular filtration.
