The application of mechanical ventilation by the isolation of the airway by intubation or tracheotomy have demonstrated therapeutic usefulness throughout the second half of this century.

Nonetheless, the use of a method which considerably distorts the normal physiology of respiration is frequently accompanied by, occasionally important, side effects. Modifications are produced in the distribution of the pulmonary air and blood flows, decrease in venous return to the thorax and reduction of heart rate, with the consequent decrease, at least temporallily, of prefusion of other organs. Hydric retention, lesser elimination of renal water and an increase of intracranial pressure are also proven effects.

The existence of tubes and cannulas in the airway facilitates the appearance of decubitous zones which may be harmful not only during the application of the technique but also posteriorly upon the withdrawal of ventilation support by residual scarring stenosis.. The high incidence of infection by gram negative germs from pharyngeal or gastric colonization in addition to the possibility of pulmonary rupture by the positive pressure generated in the airway has also been reported..

Further to the potential toxic risks of the inhalation of mixtures of gases with high proportions of oxygen, mechanical ventilation is a support of supplementary procedure for basic life activity and the faults derived from the functioning of the respirator or attending helath care staff also involves risks which influence morbimortality during the application of this technique..

CiteScore measures average citations received per document published. Read more. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Posterior glottic stenosis or interarytenoid fibrous adhesion is uncommon and has sometimes been misdiagnosed as cord paralysis.

Surfactant delivered using a minimally invasive technique, known as MIST Minimally Invasive Surfactant Therapy is a method which allows surfactant to be adminstered to a patient connected to non-invasive respiratory support. This is an increasingly used therapy in Neonatal Units that reduces the intubation rate and the pathology associated with intubation and allows the surfactant to be administered to the patients who clinically need it.. In years and in the Hospital General Universitario de Elche surfactant was delivered using this method to 19 patients, five of whom were 28 or less weeks of gestation age at birth. A comparison is made with a historical cohort consisting of 28 patients with Respiratory Distress Syndrome treated initially with non-invasive respiratory support.. No incidents were recorded that caused the interruption of the administration. A reduction in the fraction of inspired oxygen was observed in all cases after surfactant administration.
