COVID-19 pandemic: what factors compromised the mental capacity to work of nursing technicians?

Objectives: to identify the factors that influenced the mental capacity to work of nursing technicians during the COVID-19 pandemic.

Methods: a cross-sectional study, carried out at two reference hospitals in assisting the population during the COVID-19 pandemic. A total of 237 professionals from Intensive Care Units participated and answered a questionnaire.

Repercussion of the COVID-19 pandemic on the lives and work of ICU nursing technicians.

Objective: To investigate the impact of the COVID-19 pandemic on personal dimensions and its relationship with the work context of nursing technicians who worked in ICUs.

Method: A cross-sectional mixed-method study (convergent parallel). A total of 229 nursing technicians from intensive care units participated and responded a questionnaire.

Evaluation of continuous constant current and continuous pulsed current in sweat induction for cystic fibrosis diagnosis.

Background: The sweat test (ST) is the gold standard for the diagnosis of cystic fibrosis (CF). However, little is known about sweat induction using different types of currents and waves. In this context, our objective was to develop a device to induce sweat and compare the use of continuous constant current (CCC) and continuous pulsed current (CPC) in individuals with CF and healthy controls.

Does the roller pump adjustment in cardiopulmonary bypass settings influence hemolysis?

Introduction: Roller pumps are widely used in procedures involving cardiopulmonary bypass (CPB) due to their ease of operation and maintenance, safety, and cost. Several studies in the literature have compared the use of roller pumps with centrifugal pumps, but the influence of the roller pump adjustment on hemolysis has been poorly explored.

Methods: Measurements of hemolysis rates were carried out in 86 patients.

Hemolysis in extracorporeal circulation: relationship between time and procedures.

Introduction: Extracorporeal circulation (EC) is very important in cardiac surgery but causes significant damage to the blood, including hemolysis.

Objective: To quantify the rate of hemolysis at different times during EC in elective coronary artery bypass grafting.

Methods: We measured rates of hemolysis of 22 patients at 6 different times during myocardial revascularization during EC: T0 - before the start of EC, T1 - five minutes after of the EC initiation, T2 - 30 minutes of EC, T3 - immediately before the aortic unclamping, T4 - immediately before passage of the residual volume to the patient and T5 - five minutes after the passage of the residual volume to the patient.

Brazilian perfusionists and arterial roller pump adjustment: comparison between static and dynamic calibration method.

Introduction: Roller pumps play an important role in extracorporeal circulation. However, occlusion of the rollers should be adequately performed and this can be adjusted mainly by two methods: static and dynamic.

Objective: To investigate how the Brazilian perfusionists adjust arterial roller pumps in their services and evaluate the application of a Device to Assist Calibration (DAC) that facilitates roller adjustment by the dynamic calibration method.

Flow visualization in blood aspirator and cardiotomy reservoir used in cardiopulmonary bypass.

Objective: One of the major damage caused by occlusion in roller pumps is hemolysis. Comparative studies between roller pump with adjustments non occlusive and centrifugal pumps have been made in recent decades in an attempt to develop new products and adjustments that cause fewer traumas to the figurative elements of blood. Usually the roller pumps are adjusted by the static method due to concern variables flow that can occur with non-occlusive settings.
