Remote Ischemic Preconditioning Decreases Oxidative Lung Damage After Pulmonary Lobectomy
2017
BACKGROUND:During lobectomy in patients with lung cancer, the operated lung is often collapsed and hypoperfused. Ischemia/reperfusion injury may then occur when the lung is re-expanded. We hypothesized that remote ischemic preconditioning (RIPC) would decrease oxidative lung damage and improve gas e
Oxidative lung injury correlates with one-lung ventilation time during pulmonary lobectomy: a study of exhaled breath condensate and blood.
2015
OBJECTIVES: During lung lobectomy, the operated lung is collapsed and hypoperfused; oxygen deprivation is accompanied by reactive hypoxic pulmonary vasoconstriction. After lung lobectomy, ischaemia present in the collapsed state is followed by expansion–reperfusion and lung injury attributed to the production of reactive oxygen species. The primary objective of this study was to investigate the time course of several markers of oxidative stress simultaneously in exhaled breath condensate and blood and to determine the relationship between oxidative stress and one-lung ventilation time in patients undergoing lung lobectomy. METHODS: This single-centre, observational, prospective study includ…
Surgical management of benign tracheal stenosis.
2014
Abstract This chapter provides a step-by-step explanation of the indications, basic technique and pitfalls of tracheal surgery for cases of benign tracheal stenosis. Approach, trachea dissection and end-to-end anastomosis in tracheal surgery is described in detail. An algorithm for laryngotracheal technique selection according to different criteria (stenosis location, vocal cords status and tracheal mucosa and/or cartilaginous larynx involvement) is also depicted. Finally, a review of the most important reported series in tracheal surgery is presented.
Use of decellularized tracheas for airways engineering
2016
Background/Objective: Tracheal stenosis produces serious dyspnea. In some cases, a defective correction or timely intervention can lead to the death of the patient. The Hospital Clinico Universitario de Valencia is a reference hospital for the treatment of patients with airway problems exhibiting complex tracheal stenosis. Surgery is limited to a maximum length of 6-7 cm and it is not exempt of mortality (3-5%). In this study we have study the useful of decellularized porcine tracheas to be used in airway regenerative medicine. Methods: Three porcine tracheas were cut in 3 cm rings and exposed to SDS 2% for up to four weeks. Cell content was evaluated by fluorescence microscopy (DAPI) weekl…
Effects of phorbol 12,13-diacetate on human isolated bronchus
2000
Protein kinase C appears to be involved in the regulation of airway contractility. Phorbol 12,13-diacetate (PDA; 0.01-10 microM), a protein kinase C activator, produced a transient relaxation followed by a sustained contraction of human isolated bronchus. Different protein kinase C inhibitors (calphostin C, staurosporine and 1-(5-isoquinolinesulfonyl)-2-methylpiperazine) (H-7), nifedipine (NIF; 1 microM) or incubation with Ca(2+)-free medium, inhibited the spasmogenic response to phorbol, while ouabain (10 microM) suppressed only the initial relaxation. These results indicate that the initial relaxation, in response to PDA, is related to the activation of Na(+)/K(+)-ATPase, while the ensuin…
