This article reports a case of massive postoperative pneumocephalus in a patient following general anesthesia for a urological procedure. The patient had sustained a severe head injury more than 10 years ago with long-term treatment in an intensive care unit (ICU) including decompressive craniectomy, tracheostomy followed by rehabilitation, decanulation and cranioplasty. The patient recovered but suffered severe hemiparesis and mild neurocognitive deficits. ⋯ A cranial computed tomography (CT) scan revealed massive intracranial air and frontobasal skull defects. After frontobasal reconstruction, removal of an old lumboperitonal shunt and placement of a ventriculoperitoneal shunt, intracranial air was no longer observed. In summary a frontobasal injury may become symptomatic many years after injury, especially when face mask ventilation with positive pressure is applied during surgical interventions.

Post-operative endothelial dysfunction assessment using laser Doppler perfusion measurement in cardiac surgery patients.
Coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass (CPB) is associated with systemic inflammatory response and endothelial dysfunction. Our hypothesis is that CPB-induced post-operative endothelial dysfunction may be detected using laser Doppler perfusion monitoring (LDPM) in the skin microcirculation. ⋯ We observed a significant impairment of systemic microvascular endothelial function and well-preserved endothelium-independent vasodilatation in the skin microcirculation of patients 1 week after CABG surgery with CPB. Our results suggest that LDPM is a useful tool for the assessment of on-pump CABG-induced subacute post-operative endothelial dysfunctions.

ReviewPreventing and managing perioperative pulmonary complications following cardiac surgery.
To provide an update of research findings on the mechanisms underlying respiratory complications after cardiac surgery, especially acute respiratory distress syndrome, transfusion-related lung injury and ventilation-associated pneumonia. The article will review some of the preventive and therapeutic measures that can be implemented to reduce these complications, focusing on the use of protective invasive ventilation and postextubation noninvasive ventilation. ⋯ Postoperative pulmonary complications are common, but severe complications are infrequent. Their reduction requires measures to prevent infection and mechanical ventilation-associated lung injury through the use of low tidal volumes and early extubation. Noninvasive ventilation after extubation can be utilized to avoid reintubation and the associated increased morbidity and mortality. However, noninvasive ventilation should be done under rigorous conditions and by following strict criteria.
