[Analysis of characteristics of elderly patients admitted to an intensive care unit during six waves of the SARS-CoV-2 pandemic: Implications for medical care].

Objective: To analyze the characteristics of seriously ill elderly patients during the six waves of the COVID-19 pandemic.

Method: Retrospective, observational and analytical study of patients over 70 years of age admitted to the ICU (March-2020 to March-2022). Patients were categorized into three groups based on age: 70-74 years; 75-79 years; and >80 years.

Retrospective study of the effect of vaccination against SARS-CoV-2 in seriously ill patients admitted to an intensive care unit.

Background And Objective: Our study aims to compare the clinical and epidemiological characteristics, length of stay in the ICU, and mortality rates of COVID-19 patients admitted to the ICU who are fully vaccinated, partially vaccinated, or unvaccinated.

Patients And Methods: Retrospective cohort study (March 2020-March 2022). Patients were classified into unvaccinated, fully vaccinated, and partially vaccinated groups.

Meta-analysis of the effects of normal saline on mortality in intensive care.

Introduction And Objective: To evaluate, by means of a meta-analysis, the effect of normal saline on mortality in intensive care patients, when compared with the use of balanced crystalloids.

Material And Method: Published controlled clinical trials, randomised and sequential prospective studies in time, evaluating the mortality when physiological saline was used in patients admitted to intensive care units. Electronic search was performed in Medline, Embase, Cochrane Library, ISI Proceedings, and Web of Science, as well as a manual search of selected references.

Influence of Proportion of Normal Saline Administered in the Perioperative Period of Renal Transplantation on Kalemia Levels.

Background: The hyperchloremic metabolic acidosis triggered by the infusion of normal saline (NS) significantly increases the level of extracellular potassium. In this study we assessed the influence of proportion of NS administered in the perioperative period of renal transplantation on potassium levels in usual clinical practice.

Methods: This study was a retrospective cohort analysis of patients undergoing renal transplantation during a 24-month period (2015-2016).
