Observational StudyComplications of mechanical ventilation in the pediatric population.
Mechanical ventilation (MV) strategies are continuously evolving in an effort to minimize adverse events. The objective of this study was to determine the complications associated with MV in children. ⋯ MV complications occurred in 40% of patients and most often consisted of atelectasis and post-extubation stridor. Further studies are needed to examine associated risk factors and strategies to reduce their occurrence.

The cardiopulmonary bypass (CPB)-associated atelectasis accounted for most of the marked post-CPB increase in shunt and hypoxemia. We hypothesized that pressure-regulated volume-control (PRVC) modes having a distinct theoretical advantage over pressure-controlled ventilation (PCV) by providing the target tidal volume at the minimum available pressure may prove advantageous while ventilating these atelactic lungs. ⋯ PRVC may be useful in a certain group of patients to reduce intrapulmonary shunt and improve oxygenation after cardiopulmonary bypass-induced perfusion mismatch.

Critical illness myopathy and polyneuropathy - A challenge for physiotherapists in the intensive care units.
The development of critical patient related generalized neuromuscular weakness, referred to as critical illness polyneuropathy (CIP) and critical illness myopathy (CIM), is a major complication in patients admitted to intensive care units (ICU). Both CIP and CIM cause muscle weakness and paresis in critically ill patients during their ICU stay. Early mobilization or kinesiotherapy have shown muscle weakness reversion in critically ill patients providing faster return to function, reducing weaning time, and length of hospitalization. ⋯ The role of electrical stimulation is unproven as yet. Recent evidence indicates no difference between treated and untreated muscles. Future research is recommended to conduct clinical trials using neuromuscular electrical stimulation, exercises, and early mobilization as a treatment protocol in larger populations of patients in ICU.

Severe sleep disruption is a well-documented problem in mechanically ventilated, critically ill patients during their time in the intensive care unit (ICU), but little attention has been paid to the period when these patients become clinically stable and are transferred to a step-down unit (SDU). We monitored the 24-h sleep pattern in 2 groups of patients, one on mechanical ventilation and the other breathing spontaneously, admitted to our SDU to assess the presence of sleep abnormalities and their association with mechanical ventilation. ⋯ Patients admitted to an SDU after discharge from an ICU still have a wide range of sleep abnormalities. These abnormalities are mainly associated with a high severity score and alkalosis. Mechanical ventilation does not appear to be a primary cause of sleep impairment.

Noninvasive positive pressure ventilation for acute respiratory failure in children: a concise review.
Noninvasive positive pressure ventilation (NPPV) refers to the delivery of mechanical respiratory support without the use of endotracheal intubation (ETI). The present review focused on the effectiveness of NPPV in children > 1 month of age with acute respiratory failure (ARF) due to different conditions. ARF is the most common cause of cardiac arrest in children. ⋯ High FiO2 needs or high PaCO2 level on admission or within the first hours after starting NPPV appeared to be the best independent predictive factors for the NPPV failure in children with ARF. However, many important issues, such as the identification of the patient, the right time for NPPV application, and the appropriate setting, are still lacking. Further randomized, controlled trials that address these issues in children with ARF are recommended.
