Sodium Abnormalities in Cardiac Surgery With Cardiopulmonary Bypass in Adults: A Narrative Review.

Perioperative sodium abnormalities or dysnatremia is not uncommon in patients presenting for cardiac surgery and is associated with increased morbidity and mortality. Both the disease process of heart failure and its treatment may contribute to abnormalities in serum sodium concentration. Serum sodium is the main determinant of serum osmolality, which in turn affects cell volume.

Opioid-Free Anesthesia for Lung Cancer Resection: A Case-Control Study.

Objective: To assess the feasibility and effectiveness of an opioid-free anesthesia (OFA) technique in lung cancer resection surgery versus standard opioid-based techniques.

Design: Retrospective, propensity-matched, case-control study.

Setting: A single, specialty cardiothoracic center between January 2018 and July 2019.

Auricular anthropometry of newborns at the Singapore General Hospital.

Introduction: External ear abnormalities accompany many syndromes and genetic conditions. Yet, there are currently limited Asian references and no local norms for ear measurements and definitions for "low-set ears". The authors therefore describe ear measurements in a Singapore newborn population and seek to establish the applicability of the general accepted definition of "low-set ears" being that of "less than a third of the entire ear height being above the inter-medial canthal line".
