Recommendations of the Working Groups from the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) for the management of adult critically ill patients. / Recomendaciones para el tratamiento de los pacientes críticos de los Grupos de Trabajo de la Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias (SEMICYUC).

The standardization of the Intensive Care Medicine may improve the management of the adult critically ill patient. However, these strategies have not been widely applied in the Intensive Care Units (ICUs). The aim is to elaborate the recommendations for the standardization of the treatment of critical patients. A panel of experts from the thirteen working groups (WG) of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC) was selected and nominated by virtue of clinical expertise and/or scientific experience to carry out the recommendations. Available scientific literature in the management of adult critically ill patients from 2002 to 2016 was extracted. The clinical evidence was discussed and summarised by the experts in the course of a consensus finding of every WG and finally approved by the WGs after an extensive internal review process that was carried out between December 2015 and December 2016. A total of 65 recommendations were developed, of which 5 corresponded to each of the 13 WGs. These recommendations are based on the opinion of experts and scientific knowledge, and are intended as a guide for the intensivists in the management of critical patients.

Frailty in patients over 65 years of age admitted to Intensive Care Units (FRAIL-ICU). / Fragilidad en pacientes mayores de 65 años ingresados en cuidados intensivos (FRAIL-ICU).

OBJECTIVE: To estimate the prevalence of frailty in patients admitted to the Intensive Care Unit (ICU) and its impact upon ICU mortality at 1 and 6 months. DESIGN: A prospective observational cohort study was carried out. SETTING: Spanish ICU. INTERVENTION: None. PATIENTS AND METHODS: Patients≥65 years of age admitted to the ICU for>24hours. Variables were registered upon admission, and functional status was assessed by telephone calls 1 and 6 months after discharge from the ICU. MAIN STUDY VARIABLES: Age, gender, frailty (FRAIL scale), functional status (Barthel, Lawton, Clinical Dementia Rating and NUTRIC score), days of mechanical ventilation (MV), functional score (APACHE II and SOFA), ICU mortality, and mortality 1 and 6 months after ICU discharge. RESULTS: A total of 132 patients were evaluated, of which 46 were frail (34.9%). Age of the frail versus non-frail patients: 78.8±7.2 and 78.6±6.4 years, respectively (P=.43); male gender: 43.8% versus 56.3% (P=.10); SOFA score: 4.7±2.9 versus 4.6±2.9 (P=.75); MV: 33.3% versus 66.7% (P=.75); days of MV: 5.6±15 versus 4.3±8.1 (P=.57); ICU mortality 13% versus 6% (P = .14), mortality at 1 month 24% versus 8% (P = .01), mortality 6 months 32% versus 15% (P = .03). Frailty is associated with mortality at one month (OR = 3.5, P <.05, 95% CI (1.22-10.03) and at 6 months after discharge from the ICU (OR = 2.62, P <.05, 95% CI (1.04-6.56). CONCLUSIONS: Frailty was present in 35% of the patients admitted to the ICU, and was associated with mortality.

[Changes in tissue oxygen extraction in patients with acute respiratory insufficiency]. / Alteraciones en la extracción hística de oxígeno en pacientes con insuficiencia respiratoria aguda.

We analyzed the tissue oxygen extraction in 25 patients with acute respiratory failure. Fourteen met the clinical criteria for the adult respiratory distress syndrome (ARDS). The 11 remaining patients had acute respiratory failure with causes different from ARDS. In all cases the changes in the oxygen extraction ratio (O2ER) and in the oxygen consumption (VO2) were evaluated after changing oxygen availability (O2A) with positive end-expiratory pressure (PEEP) and dobutamine infusion. The patients with ARDS showed a change in VO2 parallel to O2A changes, with a significant correlation (r = 0.85); however, no changes were found in O2ER (r = 18). In the patients without ARDS, the changes in O2A did not modify the VO2 (r = 0.02) but there was a significant inverse relationship between DO2 and O2ER (r = -0.70). These findings suggest an abnormal regulation of tissue oxygen extraction and an abnormal dependence of VO2 on O2A in cases with ARDS. Dobutamine therapy, in addition to inotropic effects, could improve a situation of hidden hypoxia, as it is a vasodilator that might act on microvasculature.

[Analysis of costs and cost per diagnostic group of critically burned patients in the Spanish public health care system]. / Análisis de la financiación y del coste por proceso de los enfermos quemados críticos en el sistema público de salud español.

The financing of the National Institute of Health (INSALUD) of Spain will soon be based on Diagnosis-Related Groups (DRGs). Knowledge of the real cost of different DRGs is fundamental to ensure adequate financing and to establish criteria for comparisons between centers. Our public health system has no data on the real cost of critically burned patients and their DRGs. This retrospective descriptive study was carried out in a Major Burns Unit (MBU) and included all patients admitted between January and December 1996. Real total cost of the care of critical burned patients, cost per patient, and cost per DRG related with critical burn patients were calculated for the study period. Financing by Weighed Care Units (WCU) was compared with real costs. The total cost of the care of critical burn patients was 346,298,872 Spanish pesetas and the cost per patient was 4,439,729 ptas. WCU financing was 322,021,616 ptas and 4,128,482 ptas, respectively. The DRG with the highest total cost was 458 (non-extensive burns with skin grafts, 106,372,016 ptas). The DRG with the highest average cost was 472 (extensive burns with surgical procedure, 5,401,119 ptas). The DRG with the highest cost per stay was 457 (extensive burns without surgical procedure, 404,683 ptas). For the first time in Spain, the cost of DRGs related with critical burn patients is described. This information is necessary for DRG-based allocation of funds and for establishing criteria to compare centers. The real cost of critical burn patients exceeded WCU financing.

[Nursing care for patients with toxic epidermal necrolysis]. / Cuidados de enfermería en el paciente con necrólisis epidérmica tóxica.

Toxic Epidermal Necrolysis (TEN) is a severe skin disorder characterised by separation of the dermal-epidermal junction, as it is observed in second degree superficial burns, and it may also involve any mucosal surface area (otic, buccal, conjunctival, respiratory, genital). This condition is generally induced by the ingestion of drugs, particularly certain antibiotics, nonsteroidal antiinflammatory drugs, and antiepileptic drugs. Mortality has decreased over the last decades, from 80% to about 25% in recent series. This improvement in survival rate has been related to early diagnosis, management in specialized burn units, proper immunosuppressive treatment and intensive specialised nursing care. The main nursing diagnosis include abnormalities in the skin and mucose membranes integrity, risk of infection, loss of blood volume, risk of hypothermia, acute pain, upper airway insufficiency and anxiety. We here review the nursing care of patients with TEN. We emphasize the daily skin and mucose membranes care, and the prevention of conjunctival sinequiae, including daily conjunctival cleaning and debridement of necrotic tissue and fibrin debris using a handle needle.
