Purpose Prolonged postoperative ileus (PPOI) after abdominal surgery may effect unfavourably the patient recovery. The aim of this study was to estimate the incidence of PPOI in patients elective for colorectal resection and investigate perioperative variables associated with PPOI. Methods A consecutive series of 428 patients undergoing colorectal resection (median age 72, range 24-92, years; men/women ratio 1.14) were analyzed. Data were extracted retrospectively throughout a five-year period from an electronic prospectively maintained database...

BACKGROUND: Palliative sedation (PS) serves as a therapeutic option in cases of otherwise intractable suffering. As the use of sedative and hypnotic medication in many diverse situations is a core competency of anesthesiology, anesthesiologists are confronted with questions of sedative therapy at the end of life in institutions for specialized palliative care, in intensive care units and intermediate care wards. In recent years a number of guidelines have been published internationally but so far no official guidelines exist in Germany...

OBJECTIVE: To evaluate whether completion of vital signs assessments in pediatric transports by emergency medical services (EMS) differs by patient age. STUDY DESIGN: We reviewed records by 20 agencies in a regional EMS system in Southwestern Pennsylvania between April 1, 2013 and December 31, 2016. We abstracted demographics, vital signs (systolic blood pressure, heart rate, respiratory rate), clinical, and transport characteristics. We categorized age as neonates (≤30 days), infants (1 month to <1 year), toddler (1 to <2 years), early childhood (2 to <6 years), middle childhood (6 to <12 years), adolescent (12 to <18 years), and adult (≥18 years)...

The cardiovascular system is described by parameters including blood flow, blood distribution, blood pressure, heart rate and pulse wave velocity. Dynamic changes and mutual interactions of these parameters are important for understanding the physiological mechanisms in the cardiovascular system. The main objective of this study is to introduce a new technique based on parallel continuous bioimpedance measurements on different parts of the body along with continuous blood pressure, ECG and heart sound measurement during deep and spontaneous breathing to describe interactions of cardiovascular parameters...

Routine use of continuous positive airway pressure (CPAP) to support preterm infants with respiratory distress is an evidenced-based strategy to decrease incidence of bronchopulmonary dysplasia. However, rates of CPAP failure remain unacceptably high in very premature neonates, who are at high risk for developing bronchopulmonary dysplasia. Using the GRADE framework to assess the quality of available evidence, this article reviews strategies aimed at decreasing CPAP failure, starting with delivery room interventions and followed through to system-based efforts in the neonatal intensive care unit...

Several studies have investigated the accuracy of cervical auscultation (CA). However, both the sensitivities and the specificities of CA in detecting dysphagic conditions varied widely among these studies. These wide variations of the accuracy of CA might be caused by differences of the targeted sounds, such as the expiratory sound (ES) and/or swallowing sound (SS). Forty-six dysphagic patients were served as subjects. Patients who had unoccluded tracheostoma and patients who could not follow the instructions were excluded...

As regards the significant role of stethoscopes in the diagnosis of congenital and adventitious heart diseases and prevention of irreparable complications of these diseases, the quality of hearing sound of these stethoscopes by a physician has a significant impact on the disease diagnosis. This device plays an important role in the early diagnosis of congenital heart and respiratory diseases and provides this feasibility since birth. Also, the importance of this device performance in the diagnosis of heart, cardiovascular and respiratory diseases at different age periods is not a secret...

BACKGROUND: Timely diagnosis of acute exacerbations of COPD (AECOPD) is challenging as it depends on patients' reports. AECOPD are characterised by increased airway obstruction, mucus and air trapping, which results in changes in lung acoustics. Thus, adventitious respiratory sounds (ARS) may be useful to detect/monitor AECOPD. OBJECTIVE: To evaluate computerised ARS changes during AECOPD. METHODS: 25 non-hospitalised patients with AECOPD (16♂, 70 [62...

Lung sounds, which include all sounds that are produced during the mechanism of respiration, may be classified into normal breath sounds and adventitious sounds. Normal breath sounds occur when no respiratory problems exist, whereas adventitious lung sounds (wheeze, rhonchi, crackle, etc.) are usually associated with certain pulmonary pathologies. Heart and lung sounds that are heard using a stethoscope are the result of mechanical interactions that indicate operation of cardiac and respiratory systems, respectively...

INTRODUCTION: Duchenne muscular dystrophy (DMD) is an x linked recessive disorder. Long term prognosis is ominous, with development of respiratory distress and cardiomyopathy in advanced stage of the disease and expected death in the teens-to-mid 20s due to respiratory or cardiac failure. Peri-operative management of this patients is challenging due to difficult airway anatomy (macroglossia, limited neck and mandibular mobility). Additionally, they are at risk of developing malignant hyperthermia, rhabdomyolysis and hyperkalemic cardiac arrest when exposed to halogenated inhalational anaesthetics and depolarizing muscle relaxants...

Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung...

BACKGROUND AND OBJECTIVE: Lung sound signals convey valuable information of the lung status. Auscultation is an effective technique to appreciate the condition of the respiratory system using lung sound signals. The prior works on asthma detection from lung sound signals rely on the presence of wheeze. In this paper, we have classified normal and asthmatic subjects using advanced signal processing of posterior lung sound signals, even in the absence of wheeze. METHODS: We collected lung sounds of 60 subjects (30 normal and 30 asthma) using a novel 4-channel data acquisition system from four different positions over the posterior chest, as suggested by the pulmonologist...

In a recent publication by Henry and Royston [J. Acoust. Soc. Am. 142, 1774-1783 (2017)], an algorithm was introduced to calculate the acoustic response to externally introduced and endogenous respiratory sounds within a realistic, patient-specific subglottal airway tree. This work is extended using an efficient numerical boundary element (BE) approach to calculate the resulting radiated sound field from the airway tree into the lung parenchyma taking into account the surrounding chest wall. Within the BE model of the left lung parenchyma, comprised of more than 6000 triangular surface elements, more than 30 000 monopoles are used to approximate complex airway-originated acoustic sources...

Lung cancers may extend along or grow through the pulmonary veins to invade or lie within the left atrium (LA). A 62-year-old man, previously healthy, presented with 1-month ventilatory-independent right hemithorax back pain, dry cough and large effort dyspnea. He also referred weight loss of 12 kg in 10 months and denied hemoptysis. As antecedents, he smoked for 40 years and moderate daily alcoholism. On physical examination, the patient was in good general condition, hydrated and regular respiration at rest [blood pressure (BP) =120/80 mmHg; heart rate (HR) =90 bpm; respiratory rate (RR) =16 rpm]...

Obstructive sleep apnea (OSA) affecting human's health is a kind of major breathing-related sleep disorders and sometimes leads to nocturnal death. Respiratory rate (RR) of a sleep breathing sound signal is an important human vital sign for OSA monitoring during whole-night sleeping. A novel sleep respiratory rate detection with high computational speed based on characteristic moment waveform (CMW) method is proposed in this paper. A portable and wearable sound device is used to acquire the breathing sound signal...

The objective assessment of cough frequency is essential for evaluation of cough and antitussive therapies. Nonetheless, available algorithms for automatic detection of cough sound have limited sensitivity and the analysis of cough sound often requires input from human observers. Therefore, an algorithm for the cough sound detection with high sensitivity would be very useful for development of automatic cough monitors. Here we present a novel algorithm for cough sounds classification based on 8-dimensional numbers octonions and compare it with the algorithm based on standard neural network...

Although more than 200 years have passed since the stethoscope was invented, auscultation of the lungs is still a cornerstone in the diagnostics of asthma and other lung disorders. It is gratifying that the importance of good skills in auscultation of respiratory sounds is highlighted in a Different View article by Korppi and Lauhkonen in this issue of Acta Paediatrica (1).The stethoscope was invented in 1816 by René Théophile Hyacinthe Laennec (1781-1826), while he was a physician at l'Hôpital Necker in Paris (Figure 1) (2)...

A French physician René Laënnec invented the stethoscope for auscultation of heart and lung sounds in 1816 (1) and, more than 200 years later, the auscultation of respiratory sounds still provides experienced clinicians with useful, immediate and low-cost information on respiratory diseases. Lung auscultation is part of the physical examination and the findings should be interpreted jointly with the other clinical information that is available.Lung auscultation is a subjective method, which means that it poses a challenge with regard to transferring information on the observations between physicians...

Sleep disturbance is a significant issue for patients in intensive care units (ICUs), which can affect their health and recovery from illness. Therefore, it is important to consider ways to address sleep disturbance in these settings. One strategy that has been suggested is the use of 'quiet time' interventions, which involve a defined period where there is a reduction in controllable light and sound, and where interruptions at the patient's bedside are minimised. AIM: To determine the effectiveness of quiet time interventions in improving patients' sleep quality in ICUs; to investigate other potential clinical benefits of quiet time interventions; and to consider the effect of incorporating open visitation when implementing quiet time interventions...

Many consumer products used in our daily lives result in inhalation exposure to a variety of chemicals, although the toxicities of the active ingredients are not well known; furthermore, simultaneous exposure to chemical mixtures occurs. Sodium metabisulfite (SM) and propylene glycol (PG) are used in a variety of products. Both the cytotoxicity and the sub-acute inhalation toxicity of each chemical and their mixtures were evaluated. Assays for cell viability, membrane damage, and lysosome damage demonstrated that SM over 100 μg/ml induced significant cytotoxicity; moreover, when PG, which was not cytotoxic, was mixed with SM, the cytotoxicity of the mixture was enhanced...
