Influence of central apnea in the preterm newborn with gastroesophageal reflux disease.

Background: Gastroesophageal reflux occurs frequently in newborns. A relationship has been suspected between reflux and apnea of prematurity. The objective of this study is to determine this relationship, owing to the fact that premature newborns have immaturity of structures, especially esophageal smooth muscle.

Suture-line reinforcement with glutaraldehyde-preserved bovine pericardium for nonanatomic resection of lung tissue.

In this study we assessed the usefulness of glutaraldehyde-preserved bovine pericardium (GPBP), preparated in our laboratory, in nonanatomic resection of lung tissue in dogs. A 30% resection of the right cranial lobe of the lung was performed in 18 mongrel dogs. The suture line was reinforced with GPBP strips.

Effect of prostaglandin E2 on the tracheobronchial distribution of lung preservation perfusate.

Complete lung preservation requires the perfusate to reach the cell it intends to protect; this is directly related to the distribution of the preserving solution throughout the lung vasculature. Several prostanoids are clinically used to enhance lung preservation. We evaluated the effect of prostaglandin E2 (PGE2) on the distribution of lung perfusate throughout tracheobronchial tissue.

Plasma thromboxane B2 concentrations and pulmonary vascular resistance during lung reperfusion.

The purpose of this study was to measure the behavior of plasmatic thromboxane B2 (pITxB2) after reperfusion of a glucose-insulin-potassium preserved lung. Seven adult mongrel dogs underwent a left lung allotransplantation. Hemodynamic changes including pulmonary artery pressure and cardiac output were measured.
