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...

Michael W Jopling, Jiejing Qiu
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...

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...

BACKGROUND: Endtidal (ET) measurement of carbon dioxide is well established for intraoperative respiratory monitoring of adults and children, but the method's accuracy for intraoperative use in small newborn infants has been less extensively investigated. AIMS: The aim of this study was to compare carbon dioxide from ET measurements with arterialized capillary blood samples in newborn infants during general anesthesia and surgery. METHODS: Endtidal carbon dioxide was continuously measured during anesthesia and surgery and compared with simultaneous blood gas analyses obtained from capillary blood samples...

BACKGROUND: Death and anoxic brain injury from unrecognized postoperative respiratory depression (PORD) is a serious concern for patient safety. The American Patient Safety Foundation has called for continuous electronic monitoring for all patients receiving opioids in the postoperative period. These recommendations are based largely on consensus opinion with currently limited evidence. The objective of this study is to review the current state of knowledge on the effectiveness of continuous pulse oximetry (CPOX) versus routine nursing care and the effectiveness of continuous capnography monitoring with or without pulse oximetry for detecting PORD and preventing postoperative adverse events in the surgical ward...

The importance of capnometry and end-tidal carbon dioxide (ETCO2) has been underscored in recent years by guidelines as a method to continuously monitor adequacy of ventilation during sedation and anesthesia. Guidelines for cardiopulmonary resuscitation (CPR) recommend attempts to improve CPR quality if ETCO2 is lower than 10 mmHg. ETCO2 is thus a time-critical parameter that may benefit from being delivered in real time to health care providers. We performed a pilot study to investigate whether the addition of audible capnometric cues after each breath enhanced providers' ability to maintain appropriate ventilation over conventional capnography...

OBJECTIVE: There are conflicting data regarding the use of end-tidal carbon dioxide (PetCO2) measurement in preterm infants. The aim of this study was to evaluate the effects of different dead space to tidal volume ratios (VD/VT) on the correlation between PetCO2 and arterial carbon dioxide pressure (PaCO2) in ventilated preterm infants with respiratory distress syndrome (RDS). METHODS: We enrolled ventilated preterm infants (with assist control mode or synchronous intermittent mandatory mode) with RDS who were treated with surfactant in this prospective study...

Jihad Mallat, Benoit Vallet
In critically ill patients, tissue hypoperfusion is an important cause leading to multi- organ dysfunction and death, and it cannot always be detected by measuring standard global hemodynamic and oxygen-derived parameters. Gastric intramucosal PCO2 as measured by gastric tonometry has been recognized to be of clinical value as a prognostic factor, in assessing the effects of particular therapeutic interventions, and as an end-point of resuscitation. However, this technique has several limitations that have hampered its implementation in clinical practice...

PURPOSE OF REVIEW: The purpose of this review is to take a look on some practical aspects of anesthetic care in the endoscopy suite, concerning the general approach, safety, and monitoring issues. RECENT FINDINGS: Concerning propofol popularity for sedation during endoscopic procedures new studies create doubt in the safety of higher doses of propofol used for sedation. Careful titration of propofol, addition of synergistic supplements like ketamine and dexmedetomidine, and monitoring of anesthetic depth may limit the dose of propofol given to the patients...

BACKGROUND: The optimal approach to sedation for pleuroscopy remains undefined. Propofol is the favored sedative-hypnotic for many proceduralists but has a narrow therapeutic window and the risk for oversedation is high. Propofol-based sedation administered by anesthesiologists and the routine use of end-tidal capnography and bispectral index (BIS) monitoring may attenuate risks of complications. OBJECTIVES: The purpose of our study was to evaluate the safety and efficacy of monitored anesthesia care for pleuroscopy...

We hypothesize that capnography could detect hypoventilation during induction of bronchoscopic sedation and starting bronchoscopy following hypoventilation, may decrease hypoxemia. Patients were randomized to: starting bronchoscopy when hypoventilation (hypopnea, two successive breaths of at least 50% reduction of the peak wave compared to baseline or apnea, no wave for 10 seconds) (Study group, n = 55), or when the Observer Assessment of Alertness and Sedation scale (OAAS) was less than 4 (Control group, n = 59)...
