Dornase Alpha Versus Hypertonic Saline for Lung Atelectasis in Non-Cystic Fibrosis Patients

Atelectasis

Despite the lack of trials proving the efficacy of DNase in non cystic fibrosis patients, it is currently heavily used in this population. In fact, per evidence of barcode scanning via Meditech computer system at OU Medical Center 93% of the DNase prescribed in 2005 was for non Cystic fibrosis patients with an estimated yearly cost of $341,968.15.In vitro studies showed that the effect of Dnase was minimal on sputum viscosity when compared to Hypertonic saline . Furthermore recent studies on hypertonic saline in cystic fibrosis patients showed that it is an inexpensive and safe therapy when preceded by a bronchodilator in patients with cystic fibrosis. We hereby propose a prospective randomized trial to compare the efficacy of hypertonic saline, DNase, vs. normal saline in the treatment of atelectasis in non cystic fibrosis, mechanically ventilated patient.

Pulmonary AtelectasisPostoperative Complications3 more

The primary aim of this study is to assess the efficacy of post-operatory HFNC in reducing the incidence of hypoxemia after gynecological oncology surgery, compared to the standard application of O2 through a Venturi mask; The secondary objectives are to investigate the occurrence and entity of lung atelectasis, to evaluate diaphragmatic function and respiratory discomfort, and to evaluate the incidence of respiratory complications after seven days in the two groups. Patients will be randomized into two groups: HFNC and Control. The patients will be studied with preoperative lung and diaphragmatic ultrasound. Standard general anesthesia will be administered in the two groups. Ultrasound will be performed at arrival in the recovery room (RR) and before discharge from the RR. In the HFNC group, high-flow O2 will be administered; in the control group standard O2 therapy with Venturi mask will be administered. Arterial blood gas analysis upon arrival in the RR and after two hours of O2 therapy in both groups will be checked. The incidence of post-operative respiratory complications will be monitored in the seven days following surgery.

Prevention of Atelectasis, Via High Flow Nasal Cannula to Obtain a PEP, During General Anesthesia...

Atelectasis

Anesthesia causes respiratory changes and complications, which are the main causes of complications and anesthesia-related deaths. Among the complications, the rapid appearance of lung atelectasis is well known, deteriorating the hematosis during anesthesia, and inducing secondary pulmonary complications. Prevention or limitation of the atelectasis would be a way to improve the safety of patients who have a limited respiratory function. The application of a positive expiratory pressure (PEP) is an effective prevention method for atelectasis, that have been only demonstrate in patients under mechanical ventilation. The high flow nasal cannula is a non-invasive technique easy to perform and allowing a PEP. High flow nasal cannula is safe to use, and the interface is free from local skin complications. Chest X-ray (bad sensibility) or CT are usually used for the diagnosis of atelectasis, but these two exams involve irradiation for patient. MRI and pulmonary ultrasonography has now been validated in adults. MRI are relatively long, and allow to investigate the atelectasis with only a short additional acquisition time. Thus, it would be the first study on the effect of the PEP on the impact and the volume of the atelectasis during general anesthesia in spontaneous ventilation in children. By the way this is the first study on lung's anatomical effects of high flow nasal cannula. It is a monocentric, intervention, randomized, superiority study whose main purpose is to show the reduction of the atelectasis through the use of high flow nasal cannula versus a high concentration mask for pediatric anesthesia during MRI. The studied population is all the children between 6 months and 5 years with a pediatric indication of general anesthesia for MRI. The primary goal is to show a reduction of volume (cm3) of the atelectasis via the application of a PEP by high flow nasal cannula. The main assessment criteria is the ratio of atelectasis volume/total lung volume. The prevalence of the atelectasis will be evaluated by MRI lung and measured using 3D reconstruction software. The duration of the examination and the anesthesia is slighty lengthened, 3 to 5 minutes for a 40 minutes' exam. The secondary objective is to show a match between the atelectasis on MRI and ultrasound.

Preterm BirthPremature11 more

Infants in the neonatal intensive care unit (NICU) may be lost due to risks such as being sensitive, frequent exposure to birth complications and being prone to infection. The most common causes of mortality in newborn babies in the world; Complications due to preterm delivery (28%), infections (26%) and perinatal asphyxia (23%) were reported. Respiratory problems are observed in 4-6% of newborns. These problems are also important causes of mortality in the neonatal period. Newborn infants are more likely to have respiratory distress due to difficulties in airway calibration, few collateral airways, flexible chest wall, poor airway stability, and low functional residual capacity.Invasive mechanical ventilation (IMV) is frequently used in the treatment of newborns with respiratory failure. Various ventilation modes and strategies are used to optimize mechanical ventilation and prevent ventilator-induced lung injury. Among the important issues to be considered in newborns connected to mechanical ventilator (MV); Choosing an appropriately sized endotracheal tube to reduce airway resistance and minimize respiratory workload, correct positioning, regular nursing care, chest physiotherapy, sedation-analgesia, and infection prevention are also included.

Diaphragm Dysfunction and Ultrasound Perioperatively

Respiratory InsufficiencyPneumonia4 more

This study aims at determining whether diaphragm ultrasound examining diaphragm thickening fraction, excursion and density before and after surgery can predict respiratory complications in the postoperative period. Patients scheduled for major elective abdominal, pelvic or vascular surgery will be included in the study and diaphragm ultrasound is performed before surgery and after surgery in the postoperative ward. Physiological parameters, laboratory parameters, data on surgery and anesthesia and comorbidities will be registered. Complications such as pneumonia, desaturation, need for intubation and other respiratory events up to 30 days will be registered and later correlated with the diaphragm measurements.

Lung Recruitment Assessment With Lung Ultrasound In Pediatric Patient Scheduled For Laparoscopic...

Atelectasis

Anesthesia-induced atelectasis is a well-known entity observed in approximately 68-100% of pediatric patients undergoing general anesthesia. The collapse of dependent lung zones starts with anesthesia induction but can persist for hours or even days after surgery. Such anesthesia-related atelectasis has a number of negative clinical consequences such as the impairment of arterial blood oxygenation and lung mechanics as well as the predisposition for ventilator-associated lung injury. The adjustment of ventilator settings for preventing the occurrence of atelectasis and for reducing pulmonary complications remains controversial. Lung sonography (LUS) plays an important role in diagnosing pulmonary diseases in children, including atelectasis of different origins. LUS has demonstrated its high sensitivity and specificity for diagnosing anesthesia-induced atelectasis in children.

HFNC During Awake Craniotomy - Impact on Patient Comfort

Pulmonary AtelectasisPatient Comfort

Background: Patients undergoing awake brain surgery are exposed to non-humidified, non-warmed oxygen/air mix flow through a face mask for a prolonged duration. This causes increased discomfort, inadequate breathing with the risk for hypoxia perioperatively. Humidified high flow nasal cannula (HFNC) oxygen therapy potentially improves patient comfort, oxygen/air exchange, improves surgical conditions and prevents atelectasis of the lung, compared to traditional oxygen administration using a face mask in patients undergoing awake brain surgery. Results of this trial will be used to initiate a more extensive, multicenter trial to further characterize the potential impact of HFNC.
