Factors associated with reoperation due to bleeding and outcomes after cardiac surgery: a prospective cohort study.

OBJECTIVE: Identify the incidence and factors associated with reoperation due to bleeding in the postoperative of a cardiac surgery, in addition to the clinical outcomes of patients. METHOD: Prospective cohort study, conducted in an Intensive Care Unit (ICU), with adult patients undergoing cardiac surgery. Patients diagnosed with coagulopathies were excluded. The patients were followed up from hospitalization to hospital discharge. RESULTS: A total of 682 patients were included, and the incidence of reoperation was 3.4%. The factors associated with reoperation were history of renal failure (p = 0.005), previous use of anticoagulant (p = 0.036), higher intraoperative heart rate (p = 0.015), need for transfusion of blood component during intraoperative (p = 0.040), and higher SAPS 3 score (p < 0.001). The outcomes associated with reoperation were stroke and cardiac arrest. CONCLUSÃO: Reoperation was an event associated with greater severity, organic dysfunction, and worse clinical outcomes, but there was no difference in mortality between the groups.

Incidence of Medical Adhesive-Related Skin Injuries and Associated Factors After Pediatric Congenital Heart Surgery: A Prospective Cohort Study.

PURPOSE: The aim of this study was to identify the incidence, characteristics, and factors associated with medical adhesive-related skin injuries (MARSI). DESIGN: Prospective cohort study. SUBJECTS AND SETTINGS: The sample comprised 136 children in the postoperative period after congenital heart surgery. The study setting was in a 31-bed pediatric surgical intensive care unit (ICU) of a university hospital in Sao Paulo, Brazil. METHODS: Patients were followed from admission, with daily skin assessments, until the onset of MARSI or ICU discharge. Outcomes were compared by Fisher's exact test, Pearson's χ2 test, Mann-Whitney test, Brunner-Munzel test, and Welch 2-sample t test. RESULTS: The incidence of MARSI was 60.3%, with 85 injuries in 82 patients. The highest occurrence was on postoperative day 2 (27 wounds; 31.8%). The most frequent medical adhesive associated with MARSI was transparent film dressing (n = 74; 86.6%). Factors associated with MARSI were age (P = .000), number of devices inserted (P = .000), Braden Q Scale score (P = .005), duration of surgery (P = .021), cardiopulmonary bypass duration (P = .000), duration of mechanical ventilation (P = .000), and length of ICU stay (P = .000). Children who developed MARSI received more blood components (P = .039), vasopressors (P = .000), and corticosteroids (P = 0.000); required longer sedation (P = .000); and had more edema (P = .001). CONCLUSION: This high incidence indicates the need for greater awareness and prompt action in response to MARSI. Polyurethane transparent film without concurrent use of a skin barrier product should be avoided.

Incidence of pressure injuries and risk factors in a paediatric surgical intensive care unit: a prospective cohort study.

OBJECTIVES: The aim of the study was to evaluate the incidence of, and risk factors for, the occurrence of pressure injuries (PIs) in a paediatric surgical intensive care unit (ICU). METHOD: This is a prospective cohort study of 153 children in the postoperative period. Patients were assessed daily by physical examination and data were collected. All independent variables were included in a logistic regression. RESULTS: The mean age of the cohort was 2 years, and the incidence of PI was 15.7%. According to the Braden Q Scale, 58.2% of patients were at high risk of developing PI; 79.3% of PIs were related to immobility and 69.0% were at stage 1. Risk factors were ICU length of stay and the number of medical devices used. CONCLUSION: The incidence of PI was high because patients were mostly at a considerable risk of developing a PI. PI was associated with several factors, especially length of ICU stay and number of devices, both of which are indirect indicators of the severity of patient condition and healthcare costs.

In(compatibility) of intravenous drugs in critical units: adult cohort.

OBJECTIVES: To analyze potential (in)compatibilities of intravenous drugs based on the scheduling prepared by the nursing team. METHODS: historic cohort (retrospective) with 110 adults in critical units. Intravenous medications were identified concomitantly, whose pairs were analyzed for (in) compatibility using the screening system Trissel's™ 2 Compatibility IV-Micromedex 2.0. Parametric and non-parametric statistic were used according to the nature of the variable. RESULTS: 565 pairs of drugs were identified. Of these, 44.9% were compatible; and 8.8%, potentially incompatible. Most potentially incompatible pairs involved substances with alkaline pH such as phenytoin (32%) and sodium bicarbonate (8%) and weak acids such as midazolam (12%) and dobutamine (6%), which could result in precipitate formation. CONCLUSIONS: almost half of the mixtures simultaneously administrated was compatible, which indirectly reflects in the organized work between the nursing team and the clinical pharmaceutic in the discussions and decisions related to time scheduling.

Haemodialysis, nutritional disorders and hypoglycaemia in critical care.

This study aimed to determine hypoglycemia incidence and associated factors in critically ill patients. It looked at a retrospective cohort with 106 critically ill adult patients with 48 hours of glycaemic control and 72 hours of follow up. The dependent variable, hypoglycaemia (≤70 mg/dl), was assessed with respect to independent variables: age, diet, insulin, catecholamines, haemodialysis, nursing workload and the Simplified Acute Physiology Score. Statistical analysis was performed using Student's t-test, Fisher's exact test and logistic regression at 5% significance level. Incidence of hypoglycaemia was 14.2%. Hypoglycaemia was higher in the group of patients on catecholamines (p=0.040), with higher glycaemic variability (p<0.001) and death in the intensive care unit (p=0.008). Risk factors were identified as absence of oral diet (OR 5.11; 95% CI 1.04-25.10) and haemodialysis (OR 4.28; 95% CI 1.16-15.76). Patients on haemodialysis and with no oral diet should have their glycaemic control intensified in order to prevent and/or manage hypoglycaemic episodes.

Hipoglicemia e fatores de risco em pacientes críticos com controle glicêmico: estudo de coorte / Hipoglycemia and risk factors in critically ill patients with glycemic control: cohort study

Introdução: No âmbito da assistência ao paciente crítico, ainda persiste uma intensa e controversa discussão acerca da dificuldade da manutenção da normoglicemia, especialmente a fim de evitar episódios hipoglicêmicos. A hipoglicemia consiste em importante evento adverso e fator limitante para o controle glicêmico (CG) ideal. Objetivo: Este trabalho teve por objetivo analisar a hipoglicemia e os fatores associados em pacientes críticos. Método: Coorte retrospectiva conduzida com pacientes críticos internados nas unidades de terapia intensiva, e clínica semi-intensiva do Hospital Universitário da Universidade de São Paulo. A amostra foi composta por 106 adultos, que apresentaram CG, por, pelo menos, 48 h, e cujo seguimento foi de 72 h. A variável dependente foi hipoglicemia (70mg/dl) e independentes foram idade, dieta, uso de insulina, catecolaminas, hemodiálise, carga de trabalho de enfermagem e SAPSII. Na análise dos dados utilizaram-se os testes t de student, Exato de Fisher e regressão logística, com significância de p 0,05. Resultados: A incidência de hipoglicemia 70mg/dl foi de 14,2%. A média de idade foi 63,3 anos, com internação clínica em 67% dos casos, cerca de 40% dos pacientes tinham diabetes mellitus 39% insuficiência renal e 8% insuficiência hepática. A hipoglicemia foi associada a média da glicemia (p=0,013) variabilidade glicêmica (p=0,000), uso de catecolaminas (p=0,040), óbito na UTI (p=0,008). Foram fatores de risco a ausência de dieta via oral, OR 5,11; IC 1,04 -25,10, e a realização de hemodiálise OR 4,28; IC 1,16-15,76.O intervalo de medida glicêmica mais frequente foi de 6/6h, com poucas medidas em horários de troca de turno de trabalho e no período das 4 h às 7 h. A correlação entre medidas glicêmicas prescritas e realizadas foi de 0,880 (p=0,000). Conclusão: A hipoglicemia persiste como evento adverso no contexto das unidades críticas. A prescrição do CG, com maior ênfase na monitorização nos grupos de risco, ou seja, nos pacientes submetidos a hemodiálise e aqueles que não recebem dieta VO, pode ajudar a prevenir episódios hipoglicêmicos.

Introduction: Within the context of critical patients care, there remains an intense and controversial discussion over the difficulty of maintaining normoglycemia, especially to avoid hypoglycemic episodes. Hypoglycemia is an important adverse event and a limiting factor for an ideal glycemic control (GC). Objective: This study aimed to analyze the factors associated to hypoglycemia in critically ill patients. Methods: Retrospective cohort study conducted in critically ill patients from intensive and semi-intensive care units, of the University Hospital University of São Paulo. The sample consisted of 106 adults who had GC, for at least 48 h, and whose follow-up was 72 h. The dependent variable was hypoglycemia (70mg / dl) and independent variables were age, diet, insulin, catecholamines, hemodialysis, nursing workload and SAPSII. In the data analysis we used Students t and Fishers Exact tests and logistic regression, with significance of p 0,05. Results: The incidence of hypoglycemia 70mg / dl was 14.2%. The average age was 63.3 years, 67% were clinical patients, about 40% had diabetes mellitus, 39% had renal failure and 8% liver failure. Hypoglycemia was associated with mean blood glucose (p = 0.013) glycemic variability (p = 0.000), use of catecholamines (p = 0.040), and death in the ICU (p = 0.008). Risk factors were the absence of oral diet, OR 5.11; CI 1.04 -25.10, and hemodialysis OR 4.28; CI 1.16 to 15.76. The most frequent range of glucose measurement was 6 / 6 h,with few readings in the hours of the nursing work shift change, and from 4 h to 7 h am.The correlation between prescribed and performed glucose measurements was 0.880 (p = 0.000). Conclusion: Hypoglycemia persists as an adverse event in the context of critical units. Prescription of GC, with greater emphasis on monitoring in risk groups, namely, patients undergoing hemodialysis and those not receiving VO diet, can help prevent hypoglycemic episodes.

Infusão de insulina em terapia intensiva: ensaio controlado randomizado / Infusion de insulina en cuidados intensivos: ensayo controlado aleatorizado / Insulin infusion in intensive care: randomized controlled trial

Ensaio clínico controlado e aleatorizado que comparou o uso de protocolo de insulina intensivo e convencional na evolução clínica de pacientes em sepse grave e choque séptico, nas primeiras 72 h. Foi conduzido em um hospital universitário na cidade de São Paulo. Os pacientes (n=46) foram alocados em dois grupos: glicêmico intensivo (glicemia entre 80-110mg/dl) e convencional (180-220mg/dl). Utilizaram-se testes t-Student e Qui-Quadrado na análise dos dados. Observou-se diferença estatisticamente significativa (p<0,001) na média glicêmica, mas não houve diferença para as variáveis pressão arterial média mínima (p=0,06) e máxima (p=0,11), creatinina sérica (p=0,33) e na mortalidade (p=0,11). Apesar de não haver diferença entre os grupos quanto à mortalidade, a instabilidade hemodinâmica no grupo convencional foi mais duradoura e somente nele ocorreram óbitos. .

Ensayo clínico aleatorio controlado y randomizado que comparó el uso de protocolo de insulina intensivo y convencional en la evolución clínica de pacientes en sepsis grave y shock séptico, en las primeras 72 horas. Fue realizado en un hospital universitario de la ciudad de São Paulo. Los pacientes (n=46) fueron distribuidos en dos grupos: glucémico intensivo (glucemia entre 80-110mg/dl) y convencional (180-220mg/dl). Se utilizaron tests t-Student y Chi-cuadrado para análisis de los datos. Se observó diferencia estadísticamente significativa (p<0,001) en la media glucémica, pero no hubo diferencia para las variables presión arterial mínima (p=0,06) y máxima (p=0,11), creatinina sérica (p=0,33) y en la mortalidad (p=0,11). A pesar de no existir diferencia entre los grupos en cuanto a mortalidad, la inestabilidad hemodinámica en el grupo convencional fue más duradera y sólo en él existieron decesos. .

This randomized controlled trial compared the use of an intensive and conventional insulin protocol on clinical outcomes in patients with severe sepsis and septic shock, in the first 72 hours. It was conducted at a university hospital in the city of São Paulo. Patients (n=46) were allocated into two groups: intensive glycemic (blood glucose between 80-110mg/dl) and conventional (180-220mg/dl). The Student's t-test and chi-square test were used for data analysis. A statistically significant (p<0.001) difference was observed in mean glycemia, but there was no difference in the variables of mean minimum arterial pressure (p=0.06) or maximum (p=0.11), serum creatinine (p=0,33) or in mortality (p=0.11). Although there was no difference between the groups regarding mortality, hemodynamic instability in the conventional group was longer and the only deaths occurred in it. .
