The utility of gradient of end-tidal carbon dioxide between two lungs in lateral decubitus position in predicting a drop in oxygenation during one-lung ventilation in elective thoracic surgery- A prospective observational study.

Background And Aims: Baseline difference in the perfusion of two lungs is the cause of intra-operative shunt during one-lung ventilation (OLV). This study aimed to test the hypothesis that the gradient of end-tidal carbon dioxide (EtCO) between two lungs in lateral position (D-EtCO) would predict the quantity of shunt and hence the drop in the oxygenation during OLV.

Methods: An observational study was conducted to include consecutive 70 patients undergoing thoracic surgery using a double-lumen tube in a lateral position.

Fourth Ventricular Epidermoid Cyst - Case Series, Systematic Review and Analysis.

Background: Epidermoid cysts are extra-axial, pearly white avascular lesions mostly found in the cerebellopontine region. They are slow-growing and mostly become symptomatic when they attain significant size. They do occur at other anatomical locations, but fourth ventricle is a rare location.

Optimizing effectivity of tranexamic acid in bilateral knee arthroplasty - A prospective randomized controlled study.

Introduction: Tranexamic acid (TEA) is used in reducing surgical blood loss. Literature shows no optimal regimen recommended for Bilateral Total Knee Arthroplasty (TKA). We evaluated three TEA regimens differing in dosage, timing and mode of administration in bilateral TKA to identify the most effective regimen to reduce blood loss.
