Filter by:Acupuncture is a treatment intervention used globally for a wide variety of disorders. Its efficacy has been established over the course of 3000 years, originating in Asia and diversifying worldwide.The scientific basis for acupuncture remains unclear. Nonetheless, acupuncture releases neurochemical substrates, such as endorphins, serotonin, and norepinephrine.Acupuncture is considered to be a safe treatment when applied by a certified acupuncturist.Acupuncture has already been deployed in the treatment of sepsis or muscle weakness.Studies have revealed that acupuncture significantly improved grip strength and respiratory muscle strength in chronic obstructive pulmonary disease participates.Neuromuscular electrical stimulation (NMES) is an alternative to mobilize and exercise because it does not require active patient participation and can be used on bedridden patients.The investigators designed a study to compare the effects of acupuncture, electroacupuncture, and neuromuscular electrical stimulation on mechanical ventilation patients with weaning difficulties
The objective of the clinical investigation presented is to guarantee the safety and usability of the RESPIRA ADVANCED medical device in patients undergoing mechanical ventilation in the ICU, both stable patients and in the weaning phase. Through the clinical investigation, the reliability and durability of the device, the adequacy of the ventilatory parameters and their consistency over time, and the response of the patients wills be checked. During the entire course of the patient's participation in the study, the patient will be closely monitored following the protocol specifications, to guarantee safety and evaluate the effectiveness of the device.
Most patients in ICU are treated with a combination of analgesics and sedatives in most cases. Due to the different mechanism of different sedative and analgesic drugs, different antagonistic or synergistic effects may occur when combined with drugs, resulting in different clinical effects, especially significant effects on ventilators for patients with assisted breathing. Therefore, this study hopes to compare the effects of different sedative and analgesic drug combinations on the duration of mechanical ventilation for patients with ventilators, so as to guide the clinical adoption of a more reasonable sedative and analgesic scheme.
The study project will aim at the evaluation of the occurrence of exercise desaturation phenomenon during two different modalities of exercise (walking and stepping condition). This study will allow determining the sensibility of the 3-minute step test to detect exercise desaturation, in comparison with the gold standard (6-minute walking test). The 3-minute step test could therefore appear as a complementary tool for the evaluation of oxygen desaturation in chronic respiratory disease.
This study aims to examine the tolerance, feasibility, and physiological effects in airway clearance by using a novel non-invasive oscillating transducer device (NIOD, FrequencerTM) in critically ill children. The project is two years long with two separate stages of investigation. This study specifically examines different frequencies of NIOD to find the best frequency on patients outcomes.
Obesity is omnipresent problem in everyday anesthesiology practice associated with low level of blood oxygen (hypoxemia) during analgo-sedation. Overweight outpatients are often scheduled for colonoscopy usually undergo analgo-sedation. In obese patients, intravenous analgo-sedation often diminish respiratory drive causing hypoxemia. To avoid hypoxemia, low-flow nasal oxygenation (LFNO) of 2-6 L/min is applied via standard nasal catheter to provide maximum 40 % of inspired fraction of oxygen (FiO2). LFNO comprises applying cold and dry oxygen which causes discomfort to nasal mucosa of patient. LFNO is often insufficient to provide satisfying oxygenation. Insufficient oxygenation adds to circulatory instability - heart rate (HR) and blood pressure (BP) disorder. On the other side, high-flow nasal oxygenation (HFNO) brings 20 to 70 L/min of heated and humidified of O2/air mixture up to 100% FiO2 via specially designed nasal cannula. Heated and humidified O2/air mixture is much more agreeable to patient. HFNO brings noninvasive support to patients' spontaneous breathing by producing continuous positive pressure of 3-7 cmH2O in upper airways consequently enhancing oxygenation. Investigators intend to analyze effect of HFNO vs. LFNO on oxygen saturation during procedural analgo-sedation for colonoscopy in obese adult patients. Investigators expect that obese patients with preserved spontaneous breathing, oxygenized by HFNO vs. LFNO, will be less prone to hypoxemia thus more respiratory and circulatory stable during procedural analgo-sedation for colonoscopy. Obese patients with applied HFNO should longer preserve: normal oxygen saturation, normal level of CO2 and O2, reflecting better respiratory stability. Investigators expect obese participnts to have more stable HR and BP, reflecting improved circulatory stability. There will be less interruption of breathing pattern of obese patients and less necessity for attending anesthesiologist to intervene.
Analgo-sedation is standard procedure in anesthesiology practice and is often given for colonoscopy in the setting of daily hospital. Ideally, patients should be sedated with preserved spontaneous breathing and adequate blood O2 saturation. To maintain adequate oxygenation, low-flow O2 (2-6 L/min) is usually delivered through standard nasal catheter which can provide inspired fraction (FiO2) of 40% (low-flow nasal oxygenation - LFNO). Coldness and dryness of LFNO applied may be uncomfortable to patient. Standardly applied intravenous anesthetics can lead to transient ceasing of breathing and O2 desaturation despite LFNO. Respiratory instability can also potentiate circulatory instability - undesirable changes in heart rate (HR) and blood pressure (BP). Unlike LFNO, high-flow heated and humidified nasal oxygenation (HFNO) is characterized by the oxygen-air mixture flow of 20 to 70 L/min up to 100% FiO2. Warm and humidified O2, delivered via soft, specially designed nasal cannula, is pleasant to patient. HFNO develops continuous positive pressure of 3 to 7 cmH2O in upper airway which enables noninvasive support to patient's spontaneous breathing thus prolonging time of adequate O2 saturation. Aim of this study is to compare effect of HFNO and LFNO on oxygenation maintenance before, during and after standardized procedure of intravenous analgo-sedation in normal weight patients of ASA risk I, II and III. Investigators hypothesize that application of HFNO compared to LFNO, in patients with preserved spontaneous breathing during procedural analgo-sedation, will contribute to maintaining of adequate oxygenation, consequentially adding to greater circulatory and respiratory patients' stability. Investigators expect that patients who receive HFNO will better maintain adequate oxygenation regarding improved spontaneous breathing. Also patients will have shorter intervals of blood oxygen desaturation, less pronounced rise in blood CO2 level and lesser fall of blood O2 level, less change in HR and BP. Investigators will have to exactly estimate partial and global respiratory insufficiency (blood CO2 and O2 levels) associated with LFNO and HFNO, which will be done by blood-gas analysis of 3 arterial blood samples collected before, during and after analgo - sedation via previously, in local anesthesia, placed arterial cannula. Possible complications will be explained in written uniformed consent and by anesthesiologist.
Chronic respiratory insufficiency in patients with advanced disease to the late treatment depends mainly on mechanical ventilation and other high intensity respiratory support therapy. Strengthen the stability of chronic respiratory insufficiency intervention can reduce the frequency and extent of acute disease, saving medical resources.High-flow nasal cannula (HFNC), as a new non-invasive oxygen therapy system, has gradually become a weapon of respiratory support therapy. There is little research on the role of HFNC in oxygen therapy for chronic respiratory insufficiency. Our previous studies have found the potential value of HFNC in chronic respiratory insufficiency. The aim of this project is to promote the use of HFNC in the t reatment of chronic respiratory insufficiency in HFRS in Shanghai first, second and third grade hospitals in an effort to confirm that HFNC can improve the prognosis of patients with chronic respiratory insufficiency compared with nasal oxygen therapy.
