OBJECTIVE: Can a comprehensive, explicitly directive evidence-based guideline for all therapies that might affect the major morbidities of very low-birth-weight (VLBW) infants help a neonatal intensive care unit (NICU) further improve generally favorable morbidity rates? Can Antifragility principles of provider adaptive growth from stressors, enhanced infant risk assessment and adherence to effective therapies minimize unproven treatments and reduce all morbidities? STUDY DESIGN: Prospectively planned observational trial in VLBW infants: control group born October 2011 to September 2013 and study group October 2013 to September 2015...

BACKGROUND: Information from pulse oximeter waves confirms the presence of a pulse and helps obtain waves from tissue when the supplying artery is not readily accessible. OBJECTIVES: This study determined the predictive value of pulse oximeters for detecting improved arterial pulses after angiography. PATIENTS AND METHODS: This cross-sectional, multi-center study included 467 4-day-old to 12-year-old patients and was conducted from January 2012 to January 2016...

: Heart rate is a vital sign for assessing the need for resuscitation. We performed a systematic review of studies assessing novel methods of measuring heart rate in newborns and infants in the neonatal unit. Two investigators completed independent literature searches. Identified papers were independently evaluated and relevant data were extracted and analysed. CONCLUSION: This systematic review identified seven new technologies, including camera-based photoplethysmography, reflectance pulse oximetry, laser Doppler methods, capacitive sensors, piezoelectric sensors, electromyography, and a digital stethoscope...

BACKGROUND: Pulse oximetry does not reliably recognize respiratory depression, particularly in the presence of supplemental oxygen. Capnography frequently detects hypoventilation and apnea among children recovering from anesthesia. Although children are routinely monitored with capnography during anesthesia, reducing the rate of adverse events, it is not routinely used in the postanesthesia care unit (PACU), where patients remain at risk for respiratory depression. AIM: We hypothesized that children monitored with capnography would have more frequent staff interventions and fewer adverse events than children monitored with pulse oximetry alone...

BACKGROUND: The use of laryngeal mask airway (LMA) for fiberoptic bronchoscopy was first described in 1982. The LMA was found to be beneficial in operator view, flexibility, and also in maintaining stable oxygen saturation. Despite its advantages, the use of LMA has not become widespread. OBJECTIVE: The aim of this paper was to evaluate the safety of LMA-assisted bronchoscopy compared to standard nasal bronchoscopy. METHODS: We conducted a prospective randomized trial...

: Nocturnal pulse oximetry has a high positive predictive value for polysomnographically diagnosed obstructive sleep apnoea (OSA) in children. When significant adenotonsillar hypertrophy is diagnosed, adenotonsillectomy (T&A) represents a common treatment for OSA in children. We investigated the role of pulse oximetry in predicting those patients, referred for suspected OSA, who subsequently needed T&A. At-home nocturnal pulse oximetry was performed on 380 children (65.7% males), median age 4...

OBJECTIVES: Sleep studies for diagnosing obstructive sleep apnea (OSA) in children are laborious, expensive, inconvenient, and often not readily available. Out-of-center sleep test (OCST) devices have been studied for diagnosing OSA in adults, but few OCST studies have been done in children. The purpose of this study was to clarify the diagnostic reliability of OCST devices for children. METHODS: OCSTs using pulse oximetry and in-laboratory polysomnography (PSG) were performed separately in 686 adults and 119 children...

It can be argued that pulse oximetry is the most important technological advancement ever made in monitoring the well-being and safety of patients undergoing anesthesia. Before its development, the physical appearance of the patient and blood gas analysis were the only methods of assessing hypoxemia in patients. The disadvantages of blood gas analysis are that it is not without pain, complications, and most importantly does not provide continuous, real-time data. Although it has become de rigueur to use pulse oximetry for every anesthetic, the road leading to pulse oximetry began long ago...

Laughing-gas showman G.Q. Colton franchised dental extraction under 100% nitrous oxide in many large American cities before popularizing the practice with French Imperial Court dentist T.W. Evans in France and then England. Chicago dentist Z. Rogers helped surgeon E. Andrews oxygenate nitrous oxide, with neither man changing significantly the clinical practices of others. London's F.W. Hewitt and Pittsburgh's S.J. Hayes oxygenated anesthetics with greater clinical impact. By 1920, E.I. McKesson had publicized his practice of secondary saturation with bursts of 100% nitrous oxide to relax musculature in anesthetized patients...

When immobilising wildlife, adverse side effects can include hypoxaemia, acidosis and hypertension. Pulmonary gas exchange and acid-base status were evaluated during immobilisation of 25 free-ranging and one boma-held black rhinoceros (Diceros bicornis) in Zimbabwe. The effect of different body positions on arterial oxygenation was evaluated. A combination of the following drugs was used: an opioid (etorphine or thiafentanil), azaperone and an a2 -adrenoceptor agonist (detomidine or xylazine). Respiratory and heart rates, rectal temperature and pulse oximetry-derived haemoglobin oxygen saturation were recorded...

BACKGROUND: Speech-language therapists are specifically trained in clinically evaluating swallowing in adults with acute stroke. Incidence of dysphagia following acute stroke is high in South Africa, and health implications can be fatal, making optimal management of this patient population crucial. However, despite training and guidelines for best practice in clinically evaluating swallowing in adults with acute stroke, there are low levels of consistency in these practice patterns. OBJECTIVE: The aim was to explore the clinical practice activities of speech-language therapists in the clinical evaluation of swallowing in adults with acute stroke...

BACKGROUND: Sleep disordered breathing (SDB) is associated with decreased psychomotor vigilance (hereafter "vigilance") in clinical settings, but this association has yet to be confirmed in the general population. The aim of this study is to determine the associations between SDB and vigilance in a large sample of community-based participants. METHODS: The study sample consisted of 1508 community-dwelling Japanese persons (age: 30-79 years, women: 62.7%, mean body mass index [BMI]: 23...

BACKGROUND: Sleep-disordered breathing (SDB) or short sleep duration and coronary artery disease (CAD) are related, yet, the prevalence of SDB and short sleep duration as well as their mechanism remain unknown. Enhanced vascular inflammation is also implicated as one of the pathophysiologic mechanisms in CAD. The aims of this study were to evaluate the prevalence of patients with SDB and short sleep duration, and to examine their relationship with serum C-reactive protein (CRP) level in CAD patients...

Heart rate variability (HRV) has become an increasingly popular index of cardiac autonomic control in the biobehavioral sciences due to its relationship with mental illness and cognitive traits. However, the intraindividual stability of HRV in response to sleep and diurnal disturbances, which are commonly reported in mental illness, and its relationship with executive function are not well understood. Here, in 40 healthy adult males we calculated high frequency HRV-an index of parasympathetic nervous system (PNS) activity-using pulse oximetry during brain imaging, and assessed attentional and executive function performance in a subsequent behavioral test session at three time points: morning, evening, and the following morning...

Coarctation of aorta (CoA) is a critical congenital heart defect (CCHD) that requires accurate and immediate diagnosis and treatment. Current newborn screening methods to detect CoA lack both in sensitivity and specificity, and when suspected in a newborn, it must be confirmed using specialized imaging and expert diagnosis, both of which are usually unavailable at tertiary birthing centers. We explore the feasibility of applying machine learning methods to reliably determine the presence of this difficult-to-diagnose cardiac abnormality from ultrasound image data...

Blood gas analysis plays an important role in the initial assessment of a patient in the emergency ward. We present three different patient cases to illustrate when to opt for a venous or an arterial blood gas analysis. Arterial punctures are more painful and carry a higher risk of complications compared to venous punctures. It is possible to use a venous blood gas to screen for acute acid/base disturbances. Ventilatory compensation or anion gap cannot be calculated reliably with a venous blood gas. On the other hand, the diagnosis diabetic keto-acidosis can be made with a venous blood gas; this mode of sampling can also be used for lactate measurement at the emergency department as an independent prognostic marker for mortality...

Sedation is an essential component for gastrointestinal endoscopy. It allows patients to tolerate unpleasant endoscopic procedures by relieving anxiety, discomfort, or pain. It also reduces patient's risk of physical injury during endoscopic procedures, while providing the endoscopist with an adequate setting for a detailed examination. For the safety during endoscopic sedation, patient monitoring is crucial. Minimal monitoring requirements during endoscopic sedation are periodic assessment of blood pressure and application of continuous pulse oximetry...
