Skin temperature over the carotid artery provides an accurate noninvasive estimation of core temperature in infants and young children during general anesthesia.
The accurate measurement of core temperature is an essential aspect of intraoperative management in children. Invasive measurement sites are accurate but carry some health risks and cannot be used in certain patients. An accurate form of noninvasive thermometry is therefore needed. Our aim was to develop, and subsequently validate, separate models for estimating core temperature using different skin temperatures with an individualized correction factor. ⋯ Skin temperature over the carotid artery, with a simple correction factor of +0.52°C, provides a viable noninvasive estimate of Tnaso in young children during elective surgery with a general anesthetic.

Comparative StudyWashout times of desflurane, sevoflurane and isoflurane from the GE healthcare Aisys(®) and Avance(®) Carestation(®) and Aestiva(®) Anesthesia System.
Malignant hyperthermia susceptible patients may experience a fatal reaction to volatile anesthetic gases. This study sought to determine the washout characteristics of desflurane, sevoflurane, and isoflurane from the Aisys® , Avance® , and Aestiva® anesthesia machines. (GE Healthcare, Madison, WI, USA). ⋯ This study demonstrates that saturated vapor pressure and priming concentration exert a greater effect on washout times than gas solubility. The Aisys utilizes an electronic vaporizer system that may expose the breathing system to retained saturated vapor. The breathing systems for all machines may hinder washout of gases.

Laryngeal view and temperature measurements while using the perilaryngeal airway (Cobra-PLUS™) in children.
The Cobra-PLUS™ perilaryngeal airway (CP) is a modification of the Cobra perilaryngeal airway. It has a distal curve for easier placement and a thermistor on the pharyngeal cuff. We assessed the orientation of the larynx to the CP and compared temperatures measured using CP to temporal arterial (TA) and infrared tympanic (T) thermometers. ⋯ The CP has a better orientation to the larynx compared with its previous version. It may be used to reliably trend intraoperative temperatures.

Ultrasound-guided rectus sheath block for pyloromyotomy in infants: a retrospective analysis of a case series.
To analyze the applicability of US-guided rectus sheath block and to find out the efficacy of analgesia provided using this method without the need for opioids in conventional Hypertrophic pyloric stenosis (HPS) surgery in infants. ⋯ US-guided rectus sheath block seems to be a simple and quick method for the provision of intra- and postoperative analgesia in infants undergoing conventional HPS surgery.
