The effect of block side on hemodynamic and respiratory parameters in patients who had interscalene block for upper limb surgery.

Objective: The administration of interscalene block (ISB) may lead to several hemodynamic effects, likely due to the diffusion of local anesthetic to nearby structures such as carotid sinus baroreceptors. This study aimed to compare hemodynamic and respiratory changes resulting from right and left-sided ISB.

Patients And Methods: A retrospective analysis was conducted on adults who had ultrasound-guided ISB for upper limb surgery between January 2020 and December 2021.

Assessment of oxygen extraction rate changes following red blood cell transfusion in the intensive care unit: a protocol for a prospective observational non-interventional study.

Introduction: Haemoglobin transfusion thresholds have been used in the intensive care unit (ICU) to guide red blood cell transfusion (RBCT) decisions. Recent research has also focused on physiological indicators of tissue oxygenation as trigger points for blood transfusion. This study aims to assess the oxygen extraction rate (OER) as a critical indicator of the oxygen delivery-consumption balance in tissues and investigate its potential as a reliable trigger for blood transfusion in ICU patients by analysing clinical outcomes.

Effects of comorbidities associated with COVID-19 cases in Intensive Care Unit on mortality and disease progression.

Objective: The patient's age, gender and the presence of certain concomitant diseases have been reported to play a part in the course and progression of COVID-19 in the literature. In this study, we aimed to compare the comorbidities causing mortality in critically ill Intensive Care Unit (ICU)-patients diagnosed with COVID-19.

Patients And Methods: The data as regards the COVID-19 cases followed up in the ICU were retrospectively reviewed.

Extremely high erythrocyte sedimentation rate revisited in rheumatic diseases: a singlecenter experience.

Background: The objectives were to define the distribution of rheumatic diseases in patients with erythrocyte sedimentation rate (ESR) ≥ 100 mm/h and to find variables that can differentiate main study groups from others.

Methods: Charts of patients admitted with ESR ≥ 100 mm/h between 2015 and 2020 were reviewed. Patients were divided into four diagnostic groups based on etiology: infection (without a rheumatic diagnosis), oncologic (without a rheumatic diagnosis), rheumatic, and no definitive diagnosis.

Determination of microbial contamination on the outer surface of needleless connectors before and after disinfection.

Objectives: The aim of this study was to determine bacterial contamination of needleless connectors before and after disinfection to assess the risk for the point of catheter-related bloodstream infections.

Research Methodology/design: Experimental study design.

Setting: The research was carried out on patients with a central venous catheter hospitalized in the intensive care unit.
