This retrospective overview examines the management of patients with temporary open abdomen (OA). The clinical characteristics and intensive care treatment of 34 consecutive patients with OA (1996-2012) were reviewed. Average age was 61 years, SAPS II score 43, SOFA 8. Two patients had non-contaminated abdomen; 12 had intact gut (only 8 later during stay); 7 repaired gut (only later 4); 13 cutaneous stoma (later 14), and 2 entero-atmospheric fistula (later 8+1 entero-enteral). The median ICU stay was 48 [36-94] days. One quarter of the 2376 ICU-days were classified as severe sepsis/septic shock (antibiotics were given for two thirds of the stay); three quarters were with ventilation; in 95% of days sedatives were given (mainly enterally). Continuous cavity lavage was done in three quarters of days; in 3% of days patients were fasted whereas >20 kcal/kg was given for 74% of days; we fed the gut in 95% of fed-days, in half of them combined with parenteral nutrition. Complications a...

Pressure-support ventilation, is widely used in critically ill patients; however, the relative contribution of patient's effort during assisted breathing is difficult to measure in clinical conditions. Aim of the present study was to evaluate the performance of ultrasonographic indices of diaphragm contractile activity (respiratory excursion and thickening) in comparison to traditional indices of inspiratory muscle effort during assisted mechanical ventilation. Consecutive patients admitted to the ICU after major elective surgery who met criteria for a spontaneous breathing trial with pressure support ventilation were enrolled. Patients with airflow obstruction or after thoracic/gastric/esophageal surgery were excluded. Variable levels of inspiratory muscle effort were achieved by delivery of different levels of ventilatory assistance by random application of pressure support (0, 5 and 15 cmH2O). The right hemidiaphragm was evaluated by B- and M-mode ultrasonography to record re...

The aim of this study was to verify the capability of the Italian Group for the Evaluation of Intervention in Intensive Care Medicine (Gruppo Italiano Valutazione Interventi in Terapia Intensiva, GiViTI) Intensive Care Units (ICUs) in providing high level care (HLC) and to develop a flexible organiziational model, allowing for different levels of care in each ICU. Once the number of active beds, personnel and technology of each ICU were determined, we computed whether the available bed number and all available resources could provide HLC according to international standards. For ICUs lacking staff or equipment for safe HLC in all declared beds, we calculated the best combination between HLC and observation/monitoring beds with less need for nurses and technology (low level of care, LLC) in order to optimise the utilization of each bed. We also investigated the work organisation of physicians and nurses in these units. There are 2 070 available beds in the 293 GiViTI ICUs. To provide...

The aim of the Competency-Based Training in Intensive Care Medicine in Europe (CoBaTrICE) project is to create an internationally acceptable competency-based training program for specialists in intensive care medicine. The CoBaTrICE Project has performed a survey, in collaboration with the Picker institute, United Kingdom, to identify desirable characteristics of Intensive Care Unit (ICU) specialists, as expressed by patients and their relatives. A questionnaire was developed to assess 21 elements of professional competence. Each element was assigned to one of four categories of a Likert scale: 1=essential; 2=very important; 3=not too important; 4=does not matter. The results were dichotomized into essential (score: 1) and not essential (scores: 2-4) categories. Further, the documents were related to three key concepts: "medical skills and competencies", "communication with patients", and "communication with relatives". Questionnaire statements grouped ...

Hyponatremia is the most common electrolyte disturbance in hospitalized patients, and it represents a well-established risk factor for ICU/hospital mortality. The majority of hyponatremic states are associated with elevated arginine vasopressin levels and a preserved sodium pool. Conventional treatment is either not pathophysiologically oriented or of limited effectiveness. The aim of the present study is to investigate the use of enteral Tolvaptan in critically ill hyponatremic patients. This is a retrospective observational study in a general ICU. Patients with preserved sodium pool hyponatremia refractory to conventional therapy were enrolled. The hemodynamic, renal, and hepatic functions, together with sodium and water balance as close as possible to the drug administration and up to 72 h thereafter, were analyzed. The main outcome was a serum sodium increase of ≥ 4 mmol/L in 24 h; secondary endpoints were the ability to maintain serum sodium at 24 and 72 h, a decrease in urine sodium concentration and an increase in sodium-free diuresis. 38 patients were enrolled. The average dose of enteral Tolvaptan was 7.5 mg. 31 patients (81.6 %) increased their serum sodium >4 mmol/l/24 h; the average increase was 6.7 ± 3.4 mmol/l during the first 24 h (p < 0.001 vs baseline), and this was sustained at 72 h. No adverse effects were reported. Plasma sodium (R = -0.622, p < 0.001), urine sodium (R = -0.345, p < 0.001), central venous oxygen saturation (R = 0.401, p = 0.013), and BUN (R = -0.416, p = 0.031) before Tolvaptan were all significantly correlated with the absolute increase in serum sodium after the administration. Enteral administration of Tolvaptan seems effective in the treatment of hyponatremia with preserved sodium pool in critically ill patients. Even if the study was underpowered to detect significant side effects or complications of unwarranted fast corrections of hyponatremia, we report no complications.

We faced some of the most important aspects of the problem of the appropriateness of ICU resources use, that are the relationship between volume of activity and mortality, the analysis of cost-effectiveness in intensive care medicine, and the monitoring of the human resource use in ICU. For this aim three different surveys were utilized: one at European level, the second at country level and, third, a regional survey. After developing a new measure of volume called ''high-risk volume'', we explored the relationship between outcome and volume, founding that such association was very strong (from 3 to 1719% decrease in ICU/hospital mortality every five extra high-risk patients treated per bed per year), and that an occupancy rate larger than 80% was associated with higher mortality. Therefore, patients in all levels of risk are better treated in high-risk volume ICUs with a reasonable occupancy rate. Analysing cost-effectiveness in intensive care medicine using a natio...

The measurement of nursing workload first began in the 1970s, because of the need for determining severity of illness and cost-effectiveness in the intensive care unit. In the following decades, the need for more specific tools for assessing nursing workload brought to the development of scoring systems more focused on nursing activities. We will briefly review the scoring systems validated since 1974. TISS-Therapeutic Intervention Scoring System elaborated by Cullen in 1974 is based on 57 therapeutic procedures and was designed to assess the severity of illness in the ICU. Each intervention scores 1 to 4. Patients are grouped in 5 classes. It was not sufficiently validated and was abandoned. However it first introduced the idea of "patient point managed per nurse". TISS update was elaborated by Keene in 1983. The therapeutic procedures were increased to 76. It was assumed that a single nurse can manage 40/50 points per day. Though not validated, it became the most used to...

Oxidation of substrates is the main biochemical process used by the human body to produce energy. Different substrates (carbohydrates, lipids, and proteins) have different effects on oxygen consumption and carbon dioxide production: during the critical phase of pathologies it could be relevant pay attention to the use of various nutrients, that have some altered effect respect to the normal subjects metabolism, and during the length of metabolic treatment, too. Generally, nutrition lead to replenish body stores, while endogenous substrates are used to be oxidized. Critically ill patients show a preference for prompt energy availability (i.e. glucose) to avoid endogenous protein catabolism; lipids are shown to have a more pronounced storage effect. Adequate amount of energy intake in carbohydrates determine an increase of RQ, that means a shift from a more lipid-based to a more glucose-based oxidation. Composition of dietary intake can be usefully different for each pathology, and al...

Intensive Care Unit (ICU) patients almost uniformly suffer from sleep disruption. Even though the role of sleep disturbances is not still adequately understood, they may be related to metabolic, immune, neurological and respiratory dysfunction and could worsen the quality of life after discharge. A harsh ICU environment, underlying disease, mechanical ventilation, pain and drugs are the main reasons that underlie sleep disruption in the critically ill. Polysomnography is the gold standard in evaluating sleep, but it is not feasible in clinical practice; therefore, other objective (bispectral index score [BIS] and actigraphy) and subjective (nurse and patient assessment) methods have been proposed, but their adequacy in ICU patients is not clear. Frequent evaluation of neurological status with validated tools is necessary to avoid excessive or prolonged sedation in order to better titrate patient-focused therapy. Hypnotic agents like benzodiazepines can increase total sleep time, but...
