conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

J N MOST texts on pulmonary complications, aspiration of stomach contents 1 into the lungs during general anesthesia is considered under the heading of postanesthetic pneumonia. Aspiration of infected material is said to produce atelectasis, pne-umonia, and lung abscess .. A survey of New York Lying-In Hospital records of patients that aspirated gastric contents during obstetric anesthesia reve...

BACKGROUND Atelectasis results in impaired compliance and gas exchange and, in extreme cases, increased microvascular permeability, pulmonary hypertension, and right ventricular dysfunction. It is not known whether such atelectasis-induced lung injury is due to the direct mechanical effects of lung volume reduction and alveolar collapse or due to the associated regional lung hypoxia. The author...

background: pleurotomy during coronary artery bypass grafting (cabg) may cause post-operative events, mostly pulmonary complications. in this study, we evaluated the influence of pleurotomy during cabg on the clinical outcome following left internal mammary artery (lima) harvesting. methods: between march and august 2009, 102 patients who underwent cardiac surgery were enrolled in this study an...

12 day male patient followed with supracardiac total anomalous pulmonary venous connection (TAPVC) was admitted to our service after one of surgical repair .The extubation attempts failed three times because the atelectasis occurred in lungs. As conventional therapy improve Atelectasis, dornase alpha tested via intubation cannula . It avoided recurrence and discharged no oxygen

BACKGROUND Atelectasis can provoke pulmonary and non-pulmonary complications after general anaesthesia. Unfortunately, there is no instrument to estimate atelectasis and prompt changes of mechanical ventilation during general anaesthesia. Although arterial partial pressure of oxygen (PaO2) and intrapulmonary shunt have both been suggested to correlate with atelectasis, studies yielded inconsist...

OBJECTIVE To test the hypothesis that extended postoperative antibiotic cover would reduce the incidence of pulmonary complications in patients undergoing major head and neck surgery with tracheostomy. DESIGN A prospective, randomized, controlled trial was carried out to determine the efficacy of an extended course (5 days) of intravenous amoxicillin-clavulanic acid in reducing the rate of at...
