Filter by:The prevalence of transfusion reactions is between 1 and 11% of transfusions. Most reactions are mild and do not pose a life-threatening risk to the patient. More serious problems may be the only manifestations that lead to suspicion of a transfusion reaction. Most noninfectious transfusion reactions are immune-mediated. Two main types of reactions can be distinguished: TACO (transfusion associated cardiac overload, which is a cardiogenic pulmonary edema) and TRALI (transfusion related acute lung injury, non-cardiogenic pulmonary edema). Although TRALI are diagnoses of exclusion, the presence of noncardiogenic pulmonary edema and respiratory problems in the vicinity of blood product transfusions should raise suspicion. Other signs of TRALI are hypotension and tachycardia, while in TACO arterial hypertension with positive water balance can be observed. According to previous reports, the prevalence of transfusion reactions in the neonatal population is approximately 8%. Factors associated with these reactions are low birth weight and low gestational age. However, diagnostic criteria of respiratory transfusion reactions are not uniform across studies, and often the generic terms "acute lung injury" have been used. Therefore, the primary objective of this study is to evaluate the respiratory trend during blood transfusions; secondary objectives are the study of risk factors for the development of respiratory worsening and the possible association with complications.
Background: Pain after breast plastic surgery affects quality of life. Physical therapy offers effective interventions for this condition, such as transcutaneous electrical nerve stimulation (TENS). Although this resource has been used for more than 20 years, no studies have been published that support its use following this type of surgery. Therefore, the aim of the proposed study is to evaluate the effect of TENS on pain intensity in patients undergoing mastopexy with implants, given the existing evidence on the success of TENS for other conditions. Methods: A two-arm, randomized, sham-controlled trial will be conducted with blinded assessors. The study will be carried out at the Exercise Physiology and Metabolism Lab of Finis Terrae University. Eligible participants will be women undergoing mastopexy with implants invited by a board-certified plastic surgeon. The participants will be randomly assigned to one of two study groups: Group 1 (surgery + TENS) and Group 2 (surgery + sham TENS). TENS will be administered only one hour after surgery and will remain for one hour. Four assessments will be performed: before treatment (T0), immediately after treatment (T1), one hour (T2) and four hours after TENS (T3). The primary outcome will be pain intensity at rest, pain intensity during movement (standardized movements of both arms: anterior flexion, abduction, and external rotation), and during respiratory function tests. Secondary outcome measures will be maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and vital capacity (VC). Discussion In this study, the effects of TENS on patients with pain following mastopexy with implants will be compared to the effects of a sham TENS intervention. This RCT will offer novel evidence on the potential benefits of TENS in terms of pain intensity at rest as well as during movements and respiratory function tests.

Mechanical ventilation (MV) is a life-saving supportive therapy and one of the most common interventions implemented in intensive care. To date, only the inspiratory phase of breathing has been extensively investigated, and new MV methods have been implemented to reduce its harmful effects. Despite this, lung injury still occurs and propagates, causing multiorgan failure and patient deaths. The expiratory phase is considered unharmful and is not monitored or assisted during MV. In animal experiments, we recently showed that the loss of diaphragmatic contraction during expiration can harm the lungs during MV. During mechanical ventilation, the expiratory phase of breathing is completely disregarded. However, in all conditions that promote lung collapse, peripheral airways gradually compress and close throughout the expiration, potentially worsening lung injury. This cyclical lung collapse and consequent air-trapping may have an impact on the Starling resistor mechanisms that regulate venous return from the brain, potentially affecting cerebral perfusion and intracranial pressure. This study will investigate the incidence and the consequences of an uncontrolled expiration and expiratory lung collapse in spontaneously breathing critically ill neurosurgical patients during mechanical ventilation. Electrical impedance tomography measurements , oesophagus and gastric pressure, electrical activity of the diaphragm and intracranial pressure will be acquired in a synchronised manner during controlled mechanical ventilation, on a daily bases during assisted mechanical ventilation.
The aim of this study is to compare the preoperative and postoperative ultrasonographic measurements of patients undergoing in the prone position and the change in upper airway edema. The secondary aim of the study is to investigate the relationship between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study, and airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
Background: Multiple neonatal disorders are associated with risks of neurological injury. Thus, management of these infants should involve a coordinated approach to permit early diagnosis with improved clinical care. Such initiative involves the use of standardized protocols, continuous and specialized brain monitoring with electroencephalography (EEG), amplitude integrated EEG (aEEG) and Near Infrared Spectroscopy (NIRS), neuroimaging and training. Brazil is a very large country with disparities in health care assessment; some neonatal intensive care units (NICUs) are not well structured and trained to provide adequate neurocritical care. However, the development and implementation of these neurocritical care units requires high expertise and significant investment of time, manpower and equipment. In order to reduce the existing gap, a unique advanced telemedicine model of neurocritical care called Protecting Brains and Saving Futures (PBSF) protocol was developed and implemented in some Brazilian NICUs. Methods: A prospective observational cohort study will be conducted in 20 Brazilian NICUs that have adopted the PBSF protocol. All infants receiving the protocol during January 2021 to December 2023 will be eligible. Ethical approval will be obtained from the participating institutions. The primary objective is to describe the use of the PBSF protocol and clinical outcomes, by center and over a 3 years period. The use of the PBSF protocol will be measured by quantification of neuromonitoring, neuroimaging exams and sub-specialties consultation. Clinical outcomes of interest after the protocol implementation are length of hospital stay, detection of EEG seizures during hospitalization, use of anticonvulsants, inotropes, and fluid resuscitation, death before hospital discharge, and referral of patients to high-risk infant follow-up. These data will be also compared between infants with primarily neurologic and primarily clinical diagnosis. Discussion: The implementation of the PBSF protocol may provide adequate remote neurocritical care in high-risk infants with optimization of clinical management and improved outcomes. Data from this large, prospective, multicenter study are essential to determine whether neonatal neurocritical units can improve outcomes. Finally, it may offer the necessary framework for larger scale implementation and help in the development of studies of remote neuromonitoring.
The purpose of this study is to evaluate prospectively ventilatory practices in the perioperative cardiac surgery period.
