An accurate understanding of the position of the target lesion is essential to improve the diagnostic rate of TBNA, because failure to place the needle within the lesion is the leading cause of a low biopsy yield. The advent of new technologies such as EBUS and CT fluoroscopy has led to the concept of integration […]

The difference in percent SC suggests that the inside mucus was better hydrated than the outside RM samples. This higher water content could be due to increased humidity of the inspired air or salivary contamination of the samples during surgery. The inside samples did not appear to be contaminated on visual inspection, although this observation […]

Tracheal mucus velocity is dependent on the degree of systemic hydration. Studies in animals have shown a fall in MTR with dehydration that then returned to normal with rehydration. However, excessive systemic hydration in association with antigen-induced bronchoconstriction has also been demonstrated to reduce MTR, suggesting that there is a critical range of mucus hydration […]

Mucociliary clearance is the first line of pulmonary defense and mucus retention can lead to atelectasis and pulmonary infection. Studies in both man and animals have shown significant reductions in pulmonary mucus clearance with the administration of general anesthesia either by barbiturates or by volatile gases, although there appears to be no reduction in nasal […]

Correlations With Anesthetic Technique The age of the patients was directly correlated with the wet weight or volume collection (r = 0.52, p = 0.005) and inversely correlated with mucus spinnability (r = 0.40, p = 0.05). As an “oral pediatric premed mixture,” which included atropine and diazepam, was given to all children younger than […]

We collected 33 samples of ETT mucus from 25 people (16 male and nine female) aged 1 to 79 years (mean, 27.8 ±22.7 years). buy asthma inhaler Patients were excluded from the study if they had any history of pulmonary disease. None of the patients suffered from either respiratory allergies or from a respiratory tract […]

The magnetic microrheometer technique was used to measure the rheologic properties of microliter quantities of mucus. For these measurements, a 70- to 150-p.m steel ball is positioned in the sample of mucus and oscillated by means of an electromagnet at different driving frequencies. The magnitude of displacement of the sphere and its phase lag with […]
