Tracheostomy is one of the most frequent procedures carried out in critically ill patients with major advantages compared to translaryngeal endotracheal intubation such as reduced laryngeal anatomical alterations, reduced inspiratory load, better patient's tolerance and nursing. Thus, tracheostomy can enhance patient's care in patients who need prolonged mechanical ventilation and/or control of airways. The right timing of tracheostomy remains controversial, however it appears that early tracheostomy in selected severe trauma, burn and neurological patients could be effective to reduce the duration of mechanical ventilation intensive care stay and costs. ⋯ It is not clear the superiority of one percutaneous technique compared to another, but experience of the operator and clinical individual anatomical, physiopathological characteristics of the patient should be always considered. We believe that the operator should have experience of at least one intrusive and one extrusive percutaneous technique. The general "optimal" tracheostomy technique and timing do not exist, but tracheostomy should be targeted on the patient's individual clinical characteristics.

Respiratory tract obstruction due to a blood clot may result in life threatening ventilatory impairment. Ball valve blood clot obstructions of the airways are rare. A ball valve blood clot acts as a one-way valve, allowing (near) normal air entry into the airways, but (completely) blocking expiration. In a near fatal case of obstruction of the airways by a ball valve blood clot, we performed 'whole tube suction' to resolve the airway problem.

Positive end-expiratory pressure (PEEP) improves oxygenation and can prevent ventilator-induced lung injury in patients with acute respiratory distress syndrome (ARDS). Nevertheless, PEEP can also induce detrimental effects by its influence on the cardiovascular system. The purpose of this study was to assess the effects of PEEP on gastric mucosal perfusion while applying a protective ventilatory strategy in patients with ARDS. ⋯ PEEP of 10-20 cmH2O does not affect gastric mucosal perfusion and is hemodynamically well tolerated in most patients with ARDS, including those receiving adrenergic drugs.

Percutaneous dilatation tracheostomy in the intensive care setting presents an increasingly important concept for establishing a large-bore tracheal airway with minimal surgical intervention. Over the last years, different technical solutions have been studied to assess their respective risks and benefits to determine whether one method is actually superior. A recent observational study comparing two such techniques prompted this commentary, which reviews the current literature, comments on study design and suggests interesting topics for future research in this field.

Despite the integral role played by tracheostomy in the management of trauma patients admitted to intensive care units (ICUs), its timing remains subject to considerable practice variation. The purpose of this study is to examine the impact of early tracheostomy on the duration of mechanical ventilation, ICU length of stay, and outcomes in trauma ICU patients. ⋯ Early tracheostomy in trauma ICU patients is associated with shorter duration of mechanical ventilation and ICU LOS, without affecting ICU or hospital outcome. Adopting a standardized strategy of early tracheostomy in appropriately selected patients may help in reducing unnecessary resource utilization.
