Randomized Controlled Trial Comparative Study
Comparison between long- and short-axis techniques for ultrasound-guided cannulation of internal jugular vein.
Real-time ultrasound guidance for internal jugular (IJ) vein cannulation enhances safety and success. ⋯ Both techniques have similar outcomes when used for IJ vein cannulation.

Soluble urokinase plasminogen activation receptor (suPAR) is an emerging new biomarker, which has been shown to not only correlate with traditional biomarkers but also outperform CRP at prognosticating CVD. More clinical trials on suPAR is in the future research agenda.

Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by accumulation of excessive lung surfactant in the alveoli leading to restrictive lung functions and impaired gas exchange. Whole lung lavage (WLL) is the treatment modality of choice, which is usually performed using double lumen endobronchial tube insertion under general anesthesia and alternating unilateral lung ventilation and washing with normal saline. ⋯ Extracorporeal membrane oxygenation support (ECMO) has been used in such patients. We report a patient with autoimmune PAP following renal transplant who presented with marked hypoxemia and was managed by WLL under ECMO support.

As millions of surgical procedures are performed worldwide on an aging population with multiple comorbidities, accurate and simple perioperative risk stratification is critical. The cardiac biomarker, brain natriuretic peptide (BNP), has generated considerable interest as it is easy to obtain and appears to have powerful predictive and prognostic capabilities. ⋯ In addition, we examined the use of BNP in patients with pulmonary embolism and left ventricular assist devices. The available data strongly suggest that the addition of BNP to perioperative risk calculators is beneficial; however, whether this determination of risk will impact outcomes, remains to be seen.

Randomized Controlled Trial
A randomized trial to assess the utility of preintubation adult fiberoptic bronchoscope assessment in patients for thoracic surgery requiring one-lung ventilation.
Confirmation of placement of Double lumen endobronchial tubes (DLETT) and bronchial blockers (BBs) with the pediatric fiberoptic bronchoscope (FOB) is the most preferred practice worldwide. Most centers possess standard adult FOBs, some, particularly in developing countries might not have access to the pediatric-sized devices. We have evaluated the role of preintubation airway assessment using the former, measuring the distance from the incisors to the carina and from carina to the left and right upper lobe bronchus in deciding the depth of insertion of the lung isolation device. ⋯ Preintubation airway measurements with the adult FOB reduces airway manipulations and improves the success rate of optimal placement of DLETT and BB.
