ReviewDesign considerations for development of cuffed endotracheal tube for small airways.
Endotracheal tubes (ETTs) are life-supporting devices that are designed to maintain a patent airway in patients who are unable to sustain an airway due to illness or injury. Patients with small airways, such as neonates and pediatrics, have unique structural and functional features, making it essential that ETT design considers and executes on these particular needs. Though uncuffed ETTs have historically been preferred for patients younger than eight years of age, advances in cuffed ETT design and construction can be utilized to manufacture ETTs that are optimized for the smallest, most fragile airways. The purpose of this article is to discuss certain design features of cuffed ETTs in respect to small airways.

Multicenter StudyCaudal block, high flow oxygen insufflation and dexmedetomidine sedation for inguinal hernia surgery in infants-A prospective evaluation of an alternative anesthesia technique.
Inguinal hernia repair is the most common operation in infants, with well recognized anesthetic and perioperative risks. The aim was to investigate if the combination of caudal block, high-flow nasal oxygen insufflation and intravenous dexmedetomidine sedation is suitable for infants undergoing inguinal hernia surgery. ⋯ Caudal block, high-flow nasal oxygen insufflation and intravenous dexmedetomidine sedation is a potential alternative to general anesthesia for infant inguinal hernia surgery with a low rate of complications in this small cohort of infants.

Effect of infusion line connection and infusion line characteristics on start-up fluid delivery from syringe infusion pumps used for microinfusion.
Connecting an infusion line to a closed stopcock results in pressurization of fluid within the syringe infusion pump assembly leading to flow irregularities when opening the stopcock and activating the pump. ⋯ Both, timing of infusion line connection after purging and infusion line characteristics considerably affect intraluminal pressures and start-up fluid delivery when connecting a new syringe infusion pump assembly to a closed stopcock. Consecutive alterations in drug administration can have considerable hemodynamic consequences when dealing with catecholamine infusions in critically ill patients.
