Abstract

Abstract Background and objectives Perioperative physicians occasionally encounter situations where central venous catheters placed preoperatively turn out to be unnecessary. The purpose of this retrospective study is to identify the unnecessary application of central venous catheter placement and determine the factors associated with the unnecessary application of central venous catheter placement. Methods Using data from institutional perioperative central venous catheter surveillance, we analysed data from 1,141 patients who underwent central venous catheter placement. We reviewed the central venous catheter registry and medical charts and allocated registered patients into those with the proper or with unnecessary application of central venous catheter according to standard indications. Multivariate analysis was used to identify factors associated with the unnecessary application of central venous catheter placement. Results In 107 patients, representing 9.38% of the overall population, we identified the unnecessary application of central venous catheter placement. Multivariate analysis identified emergencies at night or on holidays (odds ratio [OR] 2.109, 95% confidence interval [95% CI] 1.021-4.359), low surgical risk (OR = 1.729, 95% CI 1.038-2.881), short duration of anesthesia (OR = 0.961/10 min increase, 95% CI 0.945-0.979), and postoperative care outside of the intensive care unit (OR = 2.197, 95% CI 1.402-3.441) all to be independently associated with the unnecessary application of catheterization. Complications related to central venous catheter placement when the procedure consequently turned out to be unnecessary were frequently observed (9/107) compared with when the procedure was necessary (40/1034) (p = 0.032, OR = 2.282, 95% CI 1.076-4.842). However, the subsequent multivariate logistic model did not hold this significant difference (p = 0.0536, OR = 2.115, 95% CI 0.988-4.526). Conclusions More careful consideration for the application of central venous catheter is required in cases of emergency surgery at night or on holidays, during low risk surgery, with a short duration of anesthesia, or in cases that do not require postoperative intensive care.

Resumo

Resumo Justificativa e objetivo No perioperatório, os médicos ocasionalmente encontram situações nas quais um cateter venoso central colocado pré-operativamente se revela desnecessário. O objetivo deste estudo retrospectivo foi identificar a colocação desnecessária de um cateter venoso central e determinar os fatores associados à colocação desnecessária de cateter venoso central. Métodos Com os dados da vigilância institucional de cateter venoso central no período perioperatório, analisamos 1.141 pacientes submetidos à colocação de cateter venoso central. Revisamos o registro de cateter venoso central e os prontuários médicos e alocamos os pacientes registrados entre aqueles com colocação adequada ou desnecessária de cateter venoso central, de acordo com as indicações padronizadas. Uma análise multivariada foi usada para identificar os fatores associados à colocação desnecessária de cateter venoso central. Resultados Em 107 pacientes, que representaram 9,38% da população global, identificamos a colocação desnecessária de cateter venoso central. A análise multivariada identificou emergências à noite ou em feriados (razão de chances [OR] 2,109; 95% de intervalo de confiança [IC 95%] 1,021-4,359), baixo risco cirúrgico (OR = 1,729; IC 95%: 1,038-2,881), curta duração da anestesia (OR = 0,961/10 min de aumento; IC 95%: 0,945-0,979) e assistência pós-operatória fora da unidade de terapia intensiva (OR = 2,197; IC 95%: 1,402-3,441), todos independentemente associados à aplicação desnecessária de cateterização. Complicações relacionadas à colocação de cateter venoso central, quando esse procedimento revelou-se desnecessário, foram frequentemente observadas (9/107), em comparação com a necessidade da execução desse procedimento (40/1.034) (p = 0,032, OR = 2,282; IC 95%: 1,076-4,842). Porém, o modelo logístico multivariável subsequente não manteve essa diferença significativa (p = 0,0536, OR = 2,1515; IC 95%: 0,988-4,526). Conclusão É preciso que uma análise mais cuidadosa seja feita sobre a colocação de cateter venoso central em casos de cirurgia de emergência à noite ou em feriados, durante cirurgia de baixo risco, em anestesia de curta duração ou em casos que não requeiram terapia intensiva no pós-operatório.
