Multicenter StudyPerioperative management and considerations in pediatric patients with connective tissue disorders undergoing cardiac surgery.
Marfan syndrome and Loeys-Dietz syndrome are connective tissue disorders associated with cardiac and vascular disease. Patients often require surgical repair, but limited data exist to describe their perioperative management. ⋯ Despite undergoing similar surgical procedures, patients with Marfan and Loeys-Dietz syndrome have different intrinsic patient characteristics and comorbidities that may affect their perioperative care. This retrospective cohort study identified some factors, but additional collection and reporting of patient data based on multicenter experience are essential for the ongoing optimization of perioperative care in these patient populations.

Safety of an improved pediatric epidural tunneling technique for catheter shear.
Epidural tunneling could help with prolonged catheterization and be effective in preventing infection and dislodgement. However, epidural tunneling techniques carry a risk of catheter shear or needlestick injuries. ⋯ Our improved epidural tunneling technique, which was designed for pediatric cases, could reduce the risk of catheter shear.

Nasopharyngeal tubes in paediatric anaesthesia: is the flow-dependent pressure drop across the tube suitable for calculating oropharyngeal pressure?
Nasopharyngeal tubes are useful in pediatric anesthesia for insufflating oxygen and anesthetics. During nasopharyngeal tube-anesthesia, gas insufflation provides some positive oropharyngeal pressure that differs from the proximal airway pressure owing to the flow-dependent pressure drop across the nasopharyngeal tube (ΔPNPT ). ⋯ During nasopharyngeal tube-assisted anesthesia, proximal airway pressure readings on the anesthetic monitoring machine overestimate oropharyngeal pressure especially for smaller-diameter nasopharyngeal tubes and higher flow, and to a lesser extent for large leaks. Given the importance of calculating oropharyngeal pressure in guiding nasopharyngeal tube ventilation in clinical practice, we propose an accurate calculation using Rohrer's equation method, or approximating oropharyngeal pressure from flow and pressure readings on the anesthetic machine using the ΔPNPT charts.
