End-tidal CO (Et) is the standard in operative care along with pulse oximetry for ventilation assessment. It is known to be less accurate in the infant population than in adults. Many neonatal intensive care units (NICU) have converted to utilizing transcutaneous CO (tcP) monitoring.

Aims: This preliminary study aimed to identify the factors affecting postdischarge nausea and vomiting in ambulatory children, specifically whether postoperative nausea and vomiting factors are contributory.
Methods: One hundred and twenty-two pediatric patients aged 5-10 years undergoing elective ambulatory surgery participated in this institution-approved study.
Brain growth across childhood is a dynamic process associated with specific energy requirements. A disproportionately higher rate of glucose utilization (CMR) compared with oxygen consumption (CMR) was documented in children's brain and suggestive of non-oxidative metabolism of glucose. Several candidate metabolic pathways may explain the CMR-CMR mismatch, and lactate production is considered a major contender.

Objective: We hypothesized that a flipped classroom improves knowledge acquisition and retention for residents compared to traditional lecture, and that residents prefer this approach.
Methods: We completed 2 iterations of a study in 2014 and 2015.
Background: A wealth of data shows neuronal demise after general anesthesia in the very young rodent brain. Herein, the authors apply proton magnetic resonance spectroscopy (1HMRS), testing the hypothesis that neurotoxic exposure during peak synaptogenesis can be tracked via changes in neuronal metabolites.
Methods: 1HMRS spectra were acquired in the brain (thalamus) of neonatal rat pups 24 and 48 h after sevoflurane exposure on postnatal day (PND) 7 and 15 and in unexposed, sham controls.
Background: We recently applied proton magnetic resonance spectroscopy (HMRS) to investigate metabolic consequences of general anesthesia in the rodent brain, and discovered that isoflurane anesthesia was characterized by higher concentrations of lactate, glutamate, and glucose in comparison with propofol. We hypothesized that the metabolomic differences between an inhalant and intravenous anesthetic observed in the rodent brain could be reproduced in the human brain.
Methods: HMRS-based metabolomic profiling was applied to characterize the cerebral metabolic status of 59 children undergoing magnetic resonance imaging during anesthesia with either sevoflurane or propofol.
Magnetic resonance (MR) imaging is generally considered a safe procedure. Contraindications include the presence of foreign objects in or on the body, which may be subject to electromagnetic fields associated with the MR system. Most of these objects are well known and are routinely screened for prior to the procedure.

Our working hypothesis was that fracture-repair might be enhanced by stimulating proliferation of chondrocytes and osteoblasts in the early stages of fracture healing followed by sequential acceleration of the remodeling process. In the present study we employed a novel device developed by us implementing a standardized fracture in rat tibiae.

Spontaneous or nontraumatic CM is even more rare and has been described in association with colorectal malignancy. These infections carry a high mortality rate and require urgent surgical intervention and intensive antibiotic therapy.
