Active clinical trials for "Respiratory Aspiration"

In the aetiology of postpartum uterine atony, hypoxia is considered an important factor although some suggest that peripheral oxygen saturation is not influenced by oxygen inhalation in women during the first and second stages of labor. Enhancing oxygen delivery to myometrium through additional inhaled oxygen may improve uterine contractions. Therefore, it is reasonable to consider that oxygen inhalation may promote myometrial contraction and prevent postpartum haemorrhage (PPH) due to uterine atony. The tendency for the uterus to relax in women encountering respiratory problems immediately after cesarean section under general anaesthesia further strengthened this theory. The aim of this study was to evaluate the effectiveness of oxygen inhalation immediately after vaginal delivery on blood loss. The investigators hypothesized that inhaled oxygen helps to maintain uterine retraction during immediate postpartum period and hence reduces vaginal blood loss.

This research aims to evaluate the effects of inspiratory muscle training (IMT) on apnea hypopnea index, sleepiness, sleep quality, cognitive function, motor task, executive function, quality of life, chemoreflex sensitivity and vagal modulation of heart rate in patients with heart failure and obstructive sleep apnea syndrome.

This is a pilot prospective cohort study of the incidence of supraglottic pH readings.

Chronic kidney disease is a renal injury and progressive and irreversible loss of kidney function and in its most advanced stage is called chronic renal failure. Although hemodialysis replace some kidney function, patients suffer some alterations characterized by "uremic syndrome" typically expressed by: motor neuropathy and/ or autonomic neuropathy, cardiac or musculoskeletal myopathies, peripheral vascular changes, among others. Thereby, the the adoption of physical exercise should be encouraged. However, it is known that the ability to exercise the subject in hemodialysis is low and they present weakness of the peripheral muscular system, including inspiratory muscles. The aim of this study is to assess the effects of inspiratory muscle training (IMT) on ventilatory muscle strength and functional capacity of patients with chronic kidney disease in hemodialysis. For this the following assessments will be performed before and after intervention: six-minute walk test to functional capacity; Kidney Disease and Quality of Life - Short Form questionnaire for quality of life; flow-mediated dilatation to endothelial function; sit-to-stand test for proximal strength of lower limbs. The subjects will be randomized into two groups, IMTG (inspiratory muscle training group) and CG (control group). The first will receive the IMT, for five weeks, three times a week, during hemodialysis session and the patients will be oriented to realize more three days at home. The control group only will be evaluated and re-evaluated. Expected results at the end of the protocol with IMT are: increased inspiratory muscle strength; longest distance covered on the six-minute walk test; improved quality of life; increased muscle strength of the lower limbs; improved endothelial function.

The purpose of the study is to verify the efficacy of using end-expiratory and end-inspiratory occlusion tests as an index of fluid responsiveness in mechanically ventilated patients with cardiac surgery.

The hospitalization for hematopoietic stem cell transplantation (HSCT) impairs the physical functioning and functional capacity, but aerobic physical training and, more recently, inspiratory muscle training, have shown benefits to patients' health submitted to this intervention. However, is not known the effect of aerobic physical training combined with inspiratory muscle training in hospitalized patients for HSCT. The purpose of the study will be verify the safety, feasibility and effects of the training association.

This study aims to compare effects of inspiratory muscle training added by aerobic training to aerobic training alone in heart failure patients with inspiratory muscle weakness. To do so, strength and endurance of inspiratory muscles, functional capacity, quality of life, heart rate variability and sleep apnea evaluations will be conducted in patients with heart failure.

Assess the effect of inspiratory muscle training on lung function, muscle strength and trunk balance in survivors of stroke in the subacute phase of the disease

The aim of the present study is to investigate the effects of additional functional inspiratory muscle training in individuals with non-specific chronic neck pain.

The goal of this research study is to compare the effects of pelvic alignment versus diaphragmatic breathing on range of motion in the shoulder joint in both athletic and nonathletic population. The investigators plan to have approximately 45 participants to take part in this study. Subjects will be assigned into three groups. Group 1 will perform both pelvic alignment and diaphragmatic breathing exercises. This group will be used as the standard or control group. Group 2 will perform pelvic alignment exercise only; and Group 3 will perform diaphragmatic exercises only. The shoulder internal rotation range will be assessed in all three groups. Maximal expiratory rate will be measured in group 3 to assure improved diaphragmatic breathing in subjects. The shoulder internal rotation range in group 2 & 3 will be compared to the shoulder range of motion in the standard group.
