Avaliação estatística e protocolo para uso de cateter central de inserção periférica na oncohematologia

Abstract

The Peripherally Inserted Central Catheter (PICC) consists of an intravenous device, installed through a peripheral vein, wich advanced to the vena cava acquiring central catheter characteristics. In this sense, the present study had as general objective: to identify the feasibility conditions for the definition of standards and protocols that allow the use of PICC in adult and pediatric patients. And as specific objectives: to analyze the performance of the first and third generation of PICC in oncohematology patients comparing with the international literature; to detect sensitive points in the context of the use of the PICC for the protocol proposal; propose an instrument for the collection and relevant investigation of data and variables; and to propose protocol of use of PICC for pediatric and adult patients. This is a descriptive prospective longitudinal observational exploratory study with a quantitative approach. The research was developed in the Hematology, Oncology and Hematology Unit (UHHO) in the following sectors: Bone Marrow Transplantation Service (STMO), High Risk Chemotherapy (QTAR) and its outpatient clinics, Intensive Care Unit (ICU), cardiac, medical clinic and pediatric in a teaching hospital in the southern region of the country. The sample was non-probabilistic, for convenience consisted of two groups, (Group 1) patients who used the first generation of PICC and (Group 2) patients who used the third generation of the device. Data were collected from January 2015 to August 2016 through an instrument developed for this study, containing 22 socio-demographic variables and 35 clinical variables. 40 firstgeneration PICCs were inserted in 36 patients by "blind" techniques, totaling 830 days of catheter, average of 20.71 days, with a minimum range of two and a maximum of 141 days. Regarding the third generation of the catheter, ten PICCs were inserted in ten patients by Ultrasound-guided Modified Seldinger Technique (TSM), totaling 397 days of catheter, mean of 39.7 days with a minimum range of ten and a maximum of 86 Days. A descriptive analysis was performed by means of the absolute frequency distribution, mean and standard deviation. Afterwards, all variables were analyzed by 'Software R', we identified 11 main components that were strongly related and formed the basis of the Structural Equations Model (MEE). These variables express themselves in a relevant way for the development of future investigations. In summary, PICC can be used successfully in most patients admitted to oncohematology and other sectors in the hospital setting, as well as in children. It can be inserted by nurses, discharging the surgical environment, anesthetic process and the specialist doctor, granting them autonomy.
