Aortic dissection is an infrequent but serious condition that often requires immediate operative intervention. We explore recent developments in the classification of aortic dissection and perioperative transesophageal echocardiography that assist with quantifying the severity of disease and facilitate its management. ⋯ Developments in the classification of aortic dissection have improved our perspective and understanding of the key presenting features that affect mortality. Improvements in patient outcome may be achieved in part by appropriately timed echocardiography-guided surgery.

Opioids have a narrow therapeutic index and have the potential to cause significant harm. Developmental and pharmacogenetic factors put children, and especially infants, at increased risk of complications. We performed a retrospective root cause analysis to identify the factors associated with critical incidents in children receiving opioid infusions in a tertiary care children's hospital. ⋯ The root causes of a range of critical incidents have been identified, and these have been used to generate recommendations for improving both patient safety and quality of analgesia for children receiving opioid infusions for acute pain management.

Observational Study
The utility of transthoracic echocardiography to confirm central line placement: An observational study.
Ultrasound visualization of neck vessels is the standard method used to assist with internal jugular vein (IJV) central line placement. Nevertheless, this practice has not eliminated the risk of carotid puncture and/or inadvertent arterial cannulation. Transesophageal echocardiography (TEE) effectively verifies wire placement within the heart but is invasive and not always available. We examined the feasibility and potential utility of using transthoracic echocardiography (TTE) to verify the distal wire in the right atrium (RA) before dilation and cannulation of the IJV. ⋯ Transthoracic echocardiography [corrected] is a feasible, noninvasive, and potentially useful method to confirm appropriate placement of the guidewire before dilation and cannulation of the IJV.

Douglas B. Craig, W.M. Wahba, Hillary Don ⋯ The work of Drs. D. Craig et al. published in the Journal more than 40 years ago was seminal to our understanding of how patient positioning has an important influence on lung volumes and on the age-related relationship between FRC and CV.
