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. ⋯ It describes 81% of the nursing time, compared to 43% of TISS 28. In conclusion, many scoring systems have been proposed to describe nursing workload, both directly (as with TOSS and PRN) or through severity and complexity of treatment (TISS, TISS 28, NAS and NEMS). These scores represent the instruments to assess the correct use of ICU resources.

[Use of protein C concentrate in adult patients with severe sepsis and septic shock].
The aim of this study is to describe the first experiences on the use of protein C concentrate (PC) in adult patients with severe sepsis and septic shock and clinical contraindications to activated protein C (APC). On the basis of the effectiveness demonstrated by the activated form in sepsis and of the encouraging results expressed in literature of protein C concentrate (PC) mainly about meningococcus fulminating infections, we carried out an observational study on protein C concentrate (PC) with 28-day follow-up and a daily analysis of the hemato-chemical and clinical parameters. Particular attention was paid to the variations in the PC plasma levels, to the modifications of the coagulation system, to the SOFA score as well as to the safety under bleeding risk conditions. ⋯ In our small number of patients, protein C concentrate has proven to be safe and particularly useful in the control of the coagulopathy triggered and sustained by sepsis.

Review[Non invasive mechanical ventilation in acute cardiogenic pulmonary edema: is it all done?].
The aim of the paper is to critically analyse the results obtained by recent literature concerning the most important aspects of application of Non Invasive Mechanical Ventilation for the treatment of Acute Cardiogenic Pulmonary Edema, and to elaborate a definition of what is, on the whole, widely accepted, focusing the attention on those issues which still remain unanswered and therefore require further studies. MEDLINE was searched and the bibliography of a selected group of articles was perused. The literature was analysed and the information gathered has proved to address the questions in a systematic way. ⋯ A good deal of favorable experimental evidence supports the use of non invasive ventilation in the acute pulmonary edema and guarantees safety when used in intensive care units. Very few trials have been carried out in order to explore application on severe pulmonary edema outside intensive care unit. A whole new world of old and new issues on patient selection criteria, ventilation times, type of ventilation and predictability of failure, could be discovered.

Primary Acute Lung Injury (ALI) after lung resection (or "post-pneumonectomy pulmonary edema") is a rare form of acute respiratory failure characterized by dyspnea, hypoxemia, diffuse infiltrates on chest radiogram, and rapid evolution often unresponsive to therapy. ALI occurs almost exclusively following pneumonectomy, within 3 days from surgery and without a preceding cause. ⋯ There is no specific therapy. Suggested measures in the perioperative care include the meticulous maintenance of physiological stability, judicious fluid restriction, and the limitation of ventilatory volumes and pressures.

ReviewMicrovasculature in ventilator-induced lung injury: target or cause?
Clinicians managing acute lung injury must reconcile the competing objectives of ensuring adequate oxygen delivery and minimizing the adverse effects of ventilatory support. Judging from our experimental work, microvascular stresses appear to be a potent cofactor in the development of pulmonary edema as well as in the expression of lung damage resulting from an injurious pattern of ventilation. ⋯ Raising ventilation frequency may also have cost. Such observations imply that reducing the demands for blood flow and ventilation are important considerations in formulating a lung protective approach to mechanical ventilation of ARDS.
