Abstract
Resumo Objetivo Identificar fatores associados à ocorrência de flebite decorrente da infusão intravenosa periférica de amiodarona em idosos. Métodos Coorte prospectiva, observacional sobre fatores de risco para ocorrência de flebite em pacientes com idade acima de 60 anos que receberam infusão intravenosa periférica de amiodarona, internados, no ano de 2012, nas unidades Coronarianas (22 leitos) e Semi Intensivas Gerais (43 leitos) de um hospital privado de grande porte, localizado na cidade de São Paulo, Brasil. Resultados Do total de 102 idosos, 34 (33,3%) apresentaram flebite. A flebite foi mais frequente em mulheres (43,6%), em membro dominante puncionado (36,2%), em veias basílica ou cefálica do antebraço (41,2%), nos dispositivos de calibre 20G (40,0%), em curativo estéril IV Fix® (39,3%), em cateter Intima® (34,3%) e quando houve reposicionamento do dispositivo (33,3%); mas essas variáveis não se associaram estatisticamente à flebite. Ausência de flebite na infusão rápida exclusiva foi marginalmente significante (p= 0,051) comparada aos diferentes tipos de infusão. Conclusão Um terço dos idosos estudados apresentou flebite, verificou-se ausência de flebite somente nas infusões rápidas exclusivas.
Highlights
The aging process causes changes that affect the cardiocirculatory system structure and may compromise the electrical stimulation conduction and generation, increasing cardiac arrhythmia prevalence in elderly people.(1) Atrial fibrillation (AF) is the most frequent condition in elderly patients admitted in emergency services
Prospective and observational cohort study on risk factors for the development of phlebitis in patients aged over 60 years, who received peripheral intravenous infusion of amiodarone, hospitalized in 2012 in the coronary care (22 beds) and general semi-intensive units (43 beds) of a large private hospital in São Paulo, Brazil
In 1983, a study showed a 73% development rate of phlebitis related to intravenous amiodarone administration;(10) in 1999, another investigation revealed lower phlebitis frequency (25%).(11) Other studies highlighted phlebitis rates lower than those published until that moment.(6,8,12) The present study reveals a 33.3% phlebitis rate in elderly patients and this result is consistent with those found in literature
Summary
The aging process causes changes that affect the cardiocirculatory system structure and may compromise the electrical stimulation conduction and generation, increasing cardiac arrhythmia prevalence in elderly people.(1) Atrial fibrillation (AF) is the most frequent condition in elderly patients admitted in emergency services. Phlebitis is an event with direct consequences for patients, especially elderly people, increasing the number of punctures, damage to peripheral venous network, aggression to the patients’ defenses, pain and discomfort. As a result, it may increase the length of hospital stay and total treatment cost.(6,7) Analysis of intravenous infusion of amiodarone in elderly patients may indicate factors especially related to phlebitis, and offer resources to prevention, aiming to reduce its occurrence and consequences for the elderly. The objective of the present study was to verify the incidence of phlebitis and identify factors associated with it due to peripheral intravenous infusion of amiodarone in elderly patients
