Despite being infrequent, complications of airway management remain an important contributor to morbidity and mortality during anaesthesia and care of the critically ill. Developments in the last three decades have made anaesthesia safer, and this has been mirrored in the equipment and techniques available for airway management. Modern technology including novel oxygenation modalities, widespread availability of capnography, second-generation supraglottic airway devices and videolaryngoscopy provide the tools to make airway management safer still...

OBJECTIVES: Volumetric capnography provides the standard CO2 elimination by the volume expired per respiratory cycle and is a measure to assess pulmonary involvement. Thus, the objective of this study was to evaluate the respiratory dynamics of healthy control subjects and those with cystic fibrosis in a submaximal exercise protocol for six minutes on the treadmill, using volumetric capnography parameters (slope 3 [Slp3], Slp3/tidal volume [Slp3/TV], and slope 2 [Slp2]). METHODS: This was a cross-sectional study with 128 subjects (cystic fibrosis, 64 subjects; controls, 64 subjects]...

Cerebrovascular dysfunction occurs early in dementia and can be identified by Transcranial Doppler ultrasonography (TCD). Few studies have examined cerebral blood flow velocity (CBFv) responses to a detailed cognitive battery. This study aimed to characterise all CBFv responses, and the effect of hemispheric dominance, to the Addenbrooke's Cognitive Examination (ACE-III) in healthy volunteers. Forty volunteers underwent continuous bilateral TCD, beat-to-beat blood pressure (MAP) (Finapres), heart rate (HR) (electrocardiogram), and end-tidal CO2 (ETCO2) (capnography) monitoring...

BACKGROUND: Evidence to date suggests that capnography monitoring during gastrointestinal endoscopic procedures (GEP) reduces the incidence of hypoxemia, but the association of capnography monitoring with the incidence of other adverse outcomes surrounding these procedures has not been well studied. Our aims were to estimate the incidence of pharmacological rescue events and death at discharge from an inpatient or outpatient hospitalization where GEP was performed with sedation, and to determine if capnography monitoring was associated with reduced incidence of these adverse outcomes...

Introduction: Dysfunctional breathing (DB) has been linked to health conditions including low back pain and neck pain and adversely effects the musculoskeletal system. Individuals with DB often have decreased pain thresholds and impaired motor control, balance, and movement. No single test or screen identifies DB, which is multi-dimensional, and includes biochemical, biomechanical, and psychophysiological components. Several tools assess and test for DB, but no screen exists to determine whether additional testing and assessment are indicated...

BACKGROUND: The Montpellier protocol for intubating patients in the intensive care unit (ICU) is associated with a decrease in intubation-related complications. We sought to determine if implementation of a simplified version of the Montpellier protocol that removed selected components and allowed for a variety of pre-oxygenation modalities increased first-pass intubation success and reduced intubation-related complications. METHODS: A prospective pre/post-comparison of a modified Montpellier protocol in two medical and one medical/surgical/cardiac ICU within a hospital system...

PURPOSE OF REVIEW: The primary objective of this review is to identify the risk factors for opioid-induced respiratory depression (OIRD) in the postoperative period. RECENT FINDINGS: In the postoperative period, OIRD has often been reported resulting in morbidity and mortality. The risk factors which predispose surgical patients to increased risk of OIRD are not clearly defined. A literature search was performed for adult surgical patients who were prescribed opioids during their hospital stay and any available reports on postoperative respiratory depression/respiratory events...

Tracheal intubation is a commonly done procedure in neonatal intensive care unit and delivery room during resuscitation. The confirmation of endotracheal tube (ETT) position should be done quickly as tube malposition is associated with various serious adverse outcomes like hypoxemia, right upper lobe collapse, atelectasis, air leak syndromes and esophageal intubation. ETT position can be confirmed by various methods like clinical sign, chest radiography, capnography, external digital tracheal palpation, ultrasonography (USG), respiratory function monitor, video-laryngoscope and fiberoptic devices...

INTRODUCTION: Capnography is routinely used for monitoring of patients subjected to sedation for different surgical procedures. There is still paucity of data highlighting the capnographic assessment of patients on midazolam sedation undergoing oral surgical procedures. Hence, we planned the present study to assess the alterations occurring in the end-tidal carbon dioxide (ETCO2) values monitored during intravenous (IV) sedation with midazolam during various oral surgical procedures. MATERIALS AND METHODS: The present study included assessment of alteration in ETCO2 values occurring during oral surgical procedure...

This review focuses on oxidative stress and more specifically lipid peroxidation in cardiac surgery, one of the fundamental theories of perioperative complications. We present the molecular pathways leading to lipid peroxidation and integrate analytical methods that allow detection of lipid peroxidation markers in the fluid phase with those focusing on volatile compounds in exhaled breath. In order to explore the accumulated data in the literature, we present a systematic review of quantitative analysis of malondialdehyde (MDA), a widely used lipid peroxidation product at various stages of cardiac surgery...

REVIEW
Stylianos Voulgarelis, John P Scott
Procedures requiring nonoperating room anesthesia (NORA) continue to increase in quantity and complexity. The roles of anesthesiologists as members of care teams in nonoperating room locations continue to evolve. The safe provision of NORA requires strict adherence to standardized monitoring guidelines including pulse oximetry, capnography, electrocardiogram, and noninvasive blood pressure ampliflier. Body temperature should also be measured in appropriate scenarios. High-risk anesthetics require advanced preparation and monitoring...

REVIEW
Tanya Duke-Novakovski
Monitoring equipment has become reliable and affordable for use in general veterinary practice. This article provides a guide to technology, troubleshooting, and obtaining quality data using 4 non-invasive techniques that are commonly used in practice. Pulse oximetry estimates oxygen saturation of hemoglobin in arterial blood, capnography measures the carbon dioxide content of inspired and expired gas, and either Doppler shift detection or oscillometry can be used to measure blood pressure. These useful non-invasive techniques all rely on adequate perfusion of the tissues for optimum function...

Heather J Becker, Melissa L Langhan
OBJECTIVE: Bag-valve mask (BVM) ventilation requires both manual skill and clinical assessment of minute ventilation. Subjective factors can make supplying appropriate ventilation difficult. Capnography is not routinely used when ventilating nonintubated patients. Our objective was to determine if providers were able to maintain normal capnography values with BVM ventilation in pediatric patients based on clinical skills alone. METHODS: Providers (nurses, residents, and fellows) delivered 2 minutes of BVM respiratory support to healthy children during induction of anesthesia for elective surgery...
