Safety and efficacy of silicone tape for indwelling urinary catheter fixation in intensive care patients-A randomized clinical trial

BACKGROUND

Critically ill patients are more vulnerable to medical adhesive-related skin injuries (MARSI), whose prevention is a constant challenge and one of the main quality indicators of nursing care. MARSI associated with indwelling urinary catheter (IUC) fixation is a relevant adverse event, mainly because of the constant involuntary traction and high skin vulnerability of the fixation site. Silicone adhesive tape has appreciable qualities for fragile skin among the range of adhesives, leading to the inference that it reduces the risk of MARSI.

AIM

To compare silicone adhesive tape for IUC fixation with acrylate tape regarding its safety and efficacy.

STUDY DESIGN

This was a randomized controlled trial blinded to the patients and evaluator. Data were collected from an intensive care unit (ICU) of a tertiary university hospital in Brazil. Patients with IUC and no MARSI at the fixation site were considered eligible. The omega (Ω) fixation technique was used for IUC fixation. A total of 132 participants were enrolled and divided into two research groups: 66 patients in the intervention group (silicone tape) and 66 in the control group (acrylate tape). Outcomes were the incidence of MARSI, patient outcome in the ICU and hospital and partial, total and overall spontaneous detachment of the tapes.

RESULTS

The overall incidence of MARSI was 28%, with 21% in the silicone group and 35% in the acrylate group, with no statistically significant difference (p = .121), including the severity of the lesions (p = .902). However, partial (p = .003) and overall (p < .001) detachment of the tapes were more frequent in the silicone group.

CONCLUSIONS

Silicone tape is no safer than acrylate tape for IUC fixation and is less adhesively effective.

RELEVANCE TO CLINICAL PRACTICE

There is no evidence to support the extensive use of silicone tape in this context.

Clinical-Epidemiological Characteristics and Mortality in Patients with Sickle Cell Anemia: A Retrospective Cohort Study of 1980 at 2018

Purpose

To analyze the clinical-epidemiological characteristics and mortality in patients with sickle-cell anemia (SCA).

Patients and Methods

A cohort study with retrospective data, conducted in two reference hospitals for SCA treatment from January 1980 to December 2018, recorded in two reference services. With a 5% significance level, the Chi-Square and Student’s t-tests were employed in the inferential statistical analysis.

Results

A total of 128 patients with SCA were studied. Diagnosis up to the fifth day of life was made in 10 patients. There were 19 deaths, of which 12 (63.2%) were female, and the average age at death was 27.05 (± 14.78) years. The leading causes of death were septic shock and cardiogenic shock. The use of invasive medical devices was considered a risk factor for death (RR=2.63; 95% CI=1.16–5.96; p=0.018), and monitoring time up to 20 years presented a 31% reduction in the risk of dying (RR=0.31; 95% CI=0.12–0.82; p=0.011) when compared to the monitoring of more than 20 years.

Conclusion

These findings are to be considered in the treatment of patients with SCA, mainly regarding early diagnosis and access to the treatment immediately afterward, since they are fundamental in improving survival and reducing severe complications.

Fatores de risco para mortalidade em pacientes com doença falciforme: uma revisão integrativa

RESUMO Objetivo Sumarizar fatores de risco e indicadores de mortalidade em pacientes com doença falciforme. Método Revisão integrativa em periódicos indexados nas bases de dados CINAHL, PubMed/MEDLINE, Science Direct/SCOPUS, SciELO e Web of Science. A questão norteadora foi elaborada por meio da estratégia Population, variable, outcome (PVO). A busca ocorreu no portal de periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior entre outubro e novembro de 2018. Resultados Dos 19 artigos, 18 eram coorte e um ensaio clínico randomizado. A amostra foi constituída, em sua maioria, pelo sexo feminino e genótipo HbSS. Se repetiram mais a taxa de mortalidade cumulativa e a curva de mortalidade global. Sete estudos identificaram fatores de risco com associação estatisticamente significativa para morte. Os mais frequentes foram o baixo nível de hemoglobina, variáveis hepáticas (enzimas fosfatase alcalina e transaminase glutâmico oxalacética) e cardiovasculares (velocidade de regurgitação da válvula tricúspide ≥ 2,5m/s). Conclusão e implicações para a prática Indicadores de mortalidade constituem ferramentas de manejo de pacientes com doença falciforme e prevenção de riscos e complicações. Há necessidade de estudos sobre os fatores relacionados à mortalidade desses pacientes. A prevenção do óbito, certamente, promoverá uma melhoria na qualidade de vida e na sobrevida dessa população.
