Study of Atelectasis by Electrical Impedance Tomography

Gynecologic Surgical ProceduresUrologic Surgical Procedures

The goal of this interventional study is to learn about the effects of different positions on the occurrence, regional distribution and reversibility of atelectasis by using a PulmoVista 500 monitor (Dräger. 23542 Lübeck), during general anesthesia with mechanical ventilation. The main questions it aims to answer are: The increase in atelectasis after induction of general anesthesia in supine and Trendelenburg position compared with baseline (spontaneous breathing) The eventual possibility of reversal of atelectasis caused by general anesthesia and Trendelenburg position by reverse Trendelenburg position and recruitment manœuvre. Participants will be adult, autonomous and able to express their will, undergoing elective gynecological or urological surgery in the extended Trendelenburg position.

Lung Recruitment Maneuvers for Postoperative Atelectasis Prevention After Idiopathic Adolescents'...

Postoperative AtelectasisLung Recruitment1 more

The 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.

Effects of Different Oxygen Concentrations on Lung Ultrasound Score During Spontaneous Ventilation...

Pulmonary Atelectasis

The 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.

Pulmonary AtelectasisMorbid Obesity1 more

The 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 Lung

The 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.

End-Expiratory Lung Volume in Children Awakening From Propofol Anesthesia

AtelectasisPostoperative Pulmonary

The 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 Atelectasis

Oxygenation 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.

Atelectasis After Inhalation or Intravenous Induction in Pediatric Anesthesia

AtelectasisPediatric Anesthesia

Children 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.
