Abstract

to describe the assembly of a low-cost paracentesis simulator and evaluate its effectiveness, acceptance and impact on the learning of medical students. a paracentesis simulator was built using a mannequin and materials such as plastic bottles, Velcro, polyvinyl chloride sheets and silicone were used. A cross-sectional and experimental study was carried out with undergraduate medical students without previous practical experience with paracentesis, which sought to validate the model, evaluating its benefits in learning and obtaining technical skills. after using the simulator there was an increase of 82.4% in the level of confidence in performing paracentesis in a patient, with 98% of respondents considering that the model fulfilled the simulator function with satisfaction, and 100% considering it useful as a teaching tool. the built simulator was effective as an educational resource, serving as an alternative to high-cost commercial models, allowing for greater accessibility in the use of this tool in medical education.

Highlights

Due to the varied etiology and high incidence of patients with ascites in medical services, the technique of paracentesis must be well-founded by medical professionals to avoid complications arising from execution errors[2-4]
Simulation is increasingly recognized as a tool for learning and improving practices that encompass medical education
The aim of this article is to describe the assembly of a low-cost paracentesis simulator and evaluate its effectiveness, acceptance and impact on the learning of medical students

Summary

Introduction

P ara of centes ascitic i s f is an in luid by t ervention puncture that c with on a sists cath of dr eter, ainage under local anesthesia. Training and repeating a certain task enables and provides the development of executing skills, in addition to working on other competencies that are important for the trainee physician, such as communication, leadership and teamwork. This path allows active learning in an environment free of biological risks and minimizes the use of animal guinea pigs[5-10]
