Lung Recruitment Maneuvers for Postoperative Atelectasis Prevention After Idiopathic Adolescents'...
Postoperative AtelectasisLung Recruitment1 moreThe investigators hypothesized that an ultrasound-guided lung recruitment maneuvers would be more effective in preventing postoperative atelectasis than conventional alveolar recruitment after surgical correction of idiopathic adolescent scoliosis.
Ultrasound-guided Lung Recruitment Maneuvers for Postoperative Pediatric Atelectasis
AtelectasisPostoperative Complications3 moreIn anesthetized children, the incidence of lung collapse with episodes of hypoxemia is high. Diaphragmatic dysfunction induced by general anesthesia is one of the most important factors in the genesis of regional losses of lung aeration. The mass of the abdominal organs pushes the diaphragm cranially compressing the lungs in the most dependent areas. Such regional lung collapse may range from a slight loss of aeration to complete atelectasis.
Use of Airway Pressure Release Ventilation in Morbidly Obese Patients Undergoing Open Heart Surgery...
Pulmonary AtelectasisMorbid Obesity1 moreThe goal of this Randomized Clinical trial is to to investigate if the use of Air Pressure Release Ventilation in morbidly obese patients undergoing open heart surgery will improve post operative pulmonary outcomes 60 Patients will be randomized into two groups according to the mode of ventilation used into: Group A: airway pressure release ventilation (APRV) group (30 Patients) Group B: Standard (control) group (30 Patients) Post-operatively, Patients will be ventilated with conventional Synchronized Intermittent Mandatory Ventilation (SIMV) volume control mode
Effect of Sustained Inflations on Lung Atelectasis During Pediatric Laparoscopic Surgery
Ventilator LungThe aim of our study is to assess the beneficial effect of sustained inflations as a recruitment manoeuvre, using LUS examinations, on the degree of lung atelectasis that occurs in pediatric patients undergoing laparoscopic surgery. Objectives To assess the effect of general anaesthesia and capnoperitoneum on lung atelectasis in the paediatric patients by using LUS examination To assess the effect of sustained inflations as a recruitment manoeuvre in decreasing lung atelectasis caused by general anaesthesia and capnoperitoneum by using LUS examination Hypothesis Our main hypothesis is that the use of repeated Sustained Inflation as a recruitment manoeuvre in pediatric patients undergoing laparoscopic surgery will result in decreased atelectasis compared to conventional ventilation.
Effects of Different Oxygen Concentrations on Lung Ultrasound Score During Spontaneous Ventilation...
Pulmonary AtelectasisThe goal of this study is to observe the effects of different oxygen concentrations during preoxygenation in spontaneous breathing patients with modified lung ultrasound scores before induction of general anesthesia. Preoxygenation is a routine and recommended procedure for patients undergoing general anesthesia. Atelectasis is a common side effect of general anesthesia and usage of high concentration oxygen is a probable cause of it. Using lower oxygen concentrations in preoxygenation may help reducing the atelectasis and it can be assessed by lung ultrasound.
End-Expiratory Lung Volume in Children Awakening From Propofol Anesthesia
AtelectasisPostoperative PulmonaryThe goal of this pilot randomized clinical trial is to test the effects of high flow nasal oxygen and head elevation during awakening from propofol anesthesia in pediatric patients undergoing airway surgery. The main question[s] it aims to answer are: High flow oxygen can decrease the occurence of atelectasis during awakening from propofol anesthesia in pediatric patients? Head elevation can decrease the occurence of atelectasis during awakening from propofol anesthesia in pediatric patients? Researchers will compare high flow oxygen vs low flow oxygen group to see if the use of high flow oxygen decrease the occurence of atelectasis during awakening from propofol anesthesia. And in each group, the patients will be assigned to supine position vs head elevation position to compare the effects of head elevation during awakening from propofol anesthesia.
Evaluation of the Effect of Novel Recruitment Maneuver Therapy for Postoperative Pulmonary Atelectasis...
Postoperative Pulmonary AtelectasisOxygenation index and bedside ultrasound would be used to evaluate the therapeutic effect of novel recruitment maneuver therapy in the patients with pulmonary atelectasis after cardiac surgery. To establish a new therapy strategy for pulmonary atelectasis after cardiac surgery and to evaluate its effectiveness and safety for the cardiac patients complicated with postoperative pulmonary atelectasis.
Role of Lung Ultrasound and Pulsed-wave Doppler in Lung Consolidations in Mechanically Ventilated...
AtelectasisPneumoniaIn infectious lung consolidations, the inhibition of hypoxic pulmonary vasoconstriction (HPV) results in a higher regional acceleration time (RAcT) compared to the RAcT measured in atelectatic consolidations.
Can the Effects of High Flow Nasal Cannula Oxygenation on Postoperative Atelectasis be Evaluated...
Postoperative AtelectasisBariatric Surgery Candidate1 moreEvaluate the effects of high-flow nasal oxygen therapy on atelectasis in the perioperative period by lung ultrasound (LUS) in bariatric surgery patients.
Atelectasis After Inhalation or Intravenous Induction in Pediatric Anesthesia
AtelectasisPediatric AnesthesiaChildren have a highly compliant chest wall and atelectasis formation occurs often during pediatric anesthesia. Inhalation induction is commonly performed in pediatric anesthesia but it is still unclear if this can have an effect on the development of atelectasis. Aim of this study is to investigate the impact of inhalation versus intravenous induction on atelectasis formation during anesthesia induction in children. Atelectasis will be evaluated with lung ultrasound before induction and right after induction.
