The mechanism by which inhaled anesthetics work is not fully understood, although they have been extensively used. Much research has been done showing the likelihood that there is more than one pathway or mechanism of action. A long-term goal of our laboratory is to decipher these mechanisms using Drosophila melanogaster, an excellent model organism for this purpose. In order to do this, we have modified and constructed an apparatus called the inebriometer to quantitatively analyze the response of flies to inhaled anesthetics. While the inebriometer is not new to the fly community, our updated design provides a relatively low-labor, high-throughput means for performing screens in search of genes involved in the anesthetic mechanism. Here we describe our construction of an airtight inebriometer that we have designed for this purpose. We also provide data that validates this apparatus and establishes a procedure for its use.

Background: Anesthetic exposure in young children raises concerns about neurodevelopmental safety, with preclinical evidence suggesting potential neurotoxicity of volatile anesthetics. This study aimed to assess whether the combination of dexmedetomidine and remifentanil, by reducing sevoflurane exposure, has any differential effect on neurodevelopmental outcomes in young children compared with sevoflurane alone.
Methods: This study was a prospective, double-blind, randomized clinical trial including children younger than 2 yr undergoing nonstaged, nonrepetitive surgeries.

Congenital diaphragmatic hernia (CDH) is a serious congenital anomaly often associated with pulmonary hypoplasia and persistent pulmonary hypertension of the newborn (PPHN). Central vascular access such as umbilical arterial catheters (UACs) is routinely used in neonatal intensive care but is associated with the risk of vascular complications, including thromboembolic events. We present a case of preterm dichorionic diamniotic (DCDA) twins born at 34 weeks of gestation with antenatally diagnosed CDH.

Using high-flow nasal cannula (HFNC) in patients with hypoxemic respiratory failure to avoid intubation raises concerns about its potential to increase mortality due to delayed intubation. Identifying at-risk patients is essential. While the literature predicts risk with oxygen-based indices (ROX, SpO2/FiO2, PaO2/FiO2), we aimed to detect ventilation insufficiency.

A retrospective analysis of dogs undergoing balloon valvuloplasty of the pulmonic valve between April 2014 and March 2023 was performed. Anaesthetic records from 44 dogs were included in the analysis. Dogs were grouped according to anaesthetic maintenance agent used, inhalational agent with partial intravenous anaesthesia (PIVA, = 31) or propofol total intravenous anaesthesia (TIVA, = 13).

Introduction: Nitrous oxide is an inhaled anaesthetic used recreationally that is neurotoxic. Corneal nerve parameters were assessed in patients with nitrous oxide toxicity.
Methods: Four individuals underwent clinical, electrophysiological and corneal confocal microscopy assessment.
