lymph node status remains an important prognostic indicator for survival in breast cancer. sentinel lymph node biopsy has become the standard method of assessment of clinically node negative breast cancers. economic implications as well as patient related factors have lead to the development a number of intra-operative techniques. review of the emerging trends in the last 4 years show that alth...

In complicated pregnancy, fetal hypoxemia rarely occurs in isolation but is often accompanied by fetal acidemia. There is growing clinical concern about the combined effects of fetal hypoxemia and fetal acidemia on neonatal outcome. However, the effects on the fetal defense responses to acute hypoxemia during fetal acidemia are not well understood. This study tested the hypothesis that fetal ac...

The work is devoted to the study of influence individualized protective ventilation support on pulmonary mecha-nics. included 47 patients who underwent open abdominal surgery under general anesthesia. All had a moderate high risk developing postoperative complications by ARISCAT scale. Intraoperatively, impact respiratory mechanics, namely Ppeak, Pplat, Pdrive, dynamic compliance was assessed. ...

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a pandemic and huge burden to healthcare systems worldwide. One of the characteristic symptoms COVID-19 is asymptomatic hypoxemia, also called happy hypoxia, silent or hypoxemia. Patients with hypoxemia often have no subjective symptoms, such as dyspnea, even though judged objectiv...

INTRODUCTION Hypoxemia is a frequent pulmonary complication in the postoperative coronary artery bypass graft. Detection of factors associated with their occurrence may indicate patients at risk for this complication, which allows tracing specific therapeutic and consequently reduce morbidity and mortality. OBJECTIVE To identify related factors to hypoxemia occurrence in immediate coronary ar...

A patient with pulmonary alveolar proteinosis underwent whole lung lavage of the right lung. Lavage of the left lung was not immediately possible because of severe hypoxemia. Three days later, after correction of hypoxemia, we re-attempted the left lung lavage. However, the patient had severe hypoxemia (SpO2 < 80%) within a few minutes of performing right one lung ventilation (OLV). On bronchos...

OBJECTIVE Hypoxemia, often assessed via pulse oximetry, is associated with neurocognitive deficits in children. The best way to qualify hypoxemia, or which level of hypoxemia already affects cognition, is unknown. METHODS We assessed the association of pulse oximetry-derived variables that qualify hypoxemia with impaired academic performance in mathematics in a population-based cross-section ...

esophagogastric varices are a frequent complication of portal hypertension. bleeding from ectopic varices of the ileum is not only life-threatening, but its accurate diagnosis is also difficult. we have presented the case of a 31-year-old man with massive hematochezia. he was a known case of non-cirrhotic portal hypertension since 15 years prior. conventional examination that included angiograp...

Pulmonary gas exchange abnormalities and refractory hypoxemia cause myriad difficulties in patients with chronic liver disease. In addition to intrinsic cardiopulmonary diseases and hepatopulmonary syndrome, some unusual pathophysiological mechanisms in patients with portosystemic collaterals might contribute to hypoxemia. We report the clinical presentation of an unusual portosystemic anatomic...
