Capillary refill time response to a fluid challenge or a vasopressor test: an observational, proof-of-concept study.

Background: Several studies have validated capillary refill time (CRT) as a marker of tissue hypoperfusion, and recent guidelines recommend CRT monitoring during septic shock resuscitation. Therefore, it is relevant to further explore its kinetics of response to short-term hemodynamic interventions with fluids or vasopressors. A couple of previous studies explored the impact of a fluid bolus on CRT, but little is known about the impact of norepinephrine on CRT when aiming at a higher mean arterial pressure (MAP) target in septic shock.

[Involvement of medical students in research. Facilitators and constraints].

Background: Scientific research is fundamental to the education of medical students. However, their involvement in research is limited.

Aim: To describe the perceptions of medical students about facilitators and constraints to perform undergraduate research.

[Participation of Chilean undergraduate medical students in scientific research].

Background: The participation of medical students in research generates professional, scientific, and personal benefits for the student.

Aim: To evaluate the interest and opportunities for medical students in Chile to participate in scientific research and their perceptions about factors influencing research.

Material And Methods: All students attending the 2018 Chilean Congress for Medical Students were invited to answer a 44 questions survey about interest and opportunities to participate in research.
