ABSTRACT

Introduction: The management of intravenous fluids is common in intensive care units, but it has been little studied in the Cuban hospital context, as has the hydromineral balance.
Objective: To describe intravenous fluid therapy and hydro-mineral balance in patients admitted to serious care services of a hospital center.
Methods: A descriptive, prospective, cross-sectional study was carried out in the second semester of 2016. They participated in the study 196 patients who had been admitted to the Intensive Care Unit at Dr. Gustavo Aldereguía Lima Hospital General Universitario in Cienfuegos. A form was completed with data obtained from the interview, physical examination and medical history of each patient during their stay. Among the variables analyzed were cause of admission, type of intravenous fluid used for hydration, hydration status, hydro-mineral balance results, and blood electrolyte values. For statistical analysis, absolute frequencies and percentages were used.
Results: Elderly patients (62.2%) were the majority in the series, those admitted for respiratory diseases (23.9%) or postoperative major surgeries (22.9%), and with history of chronic non-communicable diseases (76, 9%). Crystalloid solutions were administered in all patients and 57.7% also had the enteral route. Colloids were used in less than 10% of those admitted. The water balance was predominantly neutral (39.8%) or positive (34.2%). 94.9% of the patients were clinically normally hydrated and 74.0% had normal diuresis. Plasma sodium and potassium measurements were normal in 64.3% and 55.6%, respectively.
Conclusions: Endovenous fluid therapy was performed in elderly, polymorbid individuals with various surgical or clinical diseases. The crystalloid solutions were administered to all patients. After 24 hours in the therapy units, the patients were normally hydrated, with mainly neutral or positive fluid balances, although with variations in the blood concentration of the main electrolytes.
