Obesity, abdominal surgery, and intrathecal opioids are all Background: factors associated with a risk for respiratory compromise. The aim of this observational study was to explore the use of portable respiratory polygraphy for monitoring of obese mothers for respiratory depression the first night after caesarean section (CS) with bupivacaine/morphine/fentanyl spinal anaesthesia. Consecutive o...

BACKGROUND Hypotensive neonates who have been treated with dopamine have poorer neurodevelopmental outcome than those who have not been treated with dopamine. We speculate that dopamine stimulates adrenoceptors on cerebral arteries causing cerebral vasoconstriction. This vasoconstriction might lead to a rightward shift of the cerebral autoregulatory curve; consequently, infants treated with dop...

OBJECTIVE The aim of this study was to compare the clinical, anthropometric, and polysomnographic characteristics of a broad group of patients with sleep apnea-hypopnea syndrome according to sex. PATIENTS AND METHODS The study, conducted in 6 Spanish university hospitals, included consecutive patients attended from 2003 through 2005 with an apnea-hypopnea index greater than 5. Groups were for...

INTRODUCTION In series of cases and animal models suffering hemorrhagic shock, the use of vasopressors has shown potential benefits regarding hemodynamics and tissue perfusion. Terlipressin is an analogue of vasopressin with a longer half-life that can be administered by bolus injection. We have previously observed that hypertonic albumin improves resuscitation following controlled hemorrhage i...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

OBJECTIVE To determine if pediatric obstructive sleep apnea (OSA) improves after adenotonsillectomy (AT) regardless of tonsil size. STUDY DESIGN Case series with chart review. SETTING Pediatric Otolaryngology Department, Johns Hopkins Hospital. SUBJECTS Seventy children 1 to 18 years of age who underwent polysomnography (PSG) before and after AT. METHODS Tonsil size was evaluated using ...

BACKGROUND Obstructive sleep apnea (OSA) is an established cause of hypertension. However, it is not clear whether the frequency of masked hypertension in patients with OSA and whether OSA have an independent role on arterial stiffness taking into account ambulatory blood pressure (BP) monitoring (ABPM). METHODS We evaluated 61 male normotensive participants as determined by casual clinic BP ...

STUDY OBJECTIVE Changes in sleep-disordered breathing associated with late pregnancy have not previously been systematically investigated; however, a number of case reports indicate exacerbation of obstructive sleep apnea in late pregnancy, often in association with maternal hypertension. We aimed to compare the severity of sleep-disordered breathing and associated maternal blood-pressure respo...

Data analysis is an essential part of scientific research and engineering applications. A proper data analysis method will provide a better understanding of the process under consideration, for example, extracting useful parameters to validate an existing theory or to inspire a new theory. However, data from the real world, such as field-observation data, well-controlled laboratory experiments,...

OBJECTIVES/HYPOTHESIS To determine if sleepiness and sleep study variables (e.g., Apnea-Hypopnea Index [AHI] and lowest oxygen saturation) improve following isolated tonsillectomy for adult obstructive sleep apnea (OSA). STUDY DESIGN Systematic review and meta-analysis. METHODS Nine databases (PubMed/MEDLINE included) were searched through November 24, 2015. RESULTS Seventeen studies (n =...
