Filter by:General anesthesia is characterized by temporary loss of consciousness and decreased reflex activity without any change in vital functions. It can be performed with intravenous and/or inhalation agents. During general anesthesia, breathing is stopped and respiratory support is provided to patients with various respiratory equipment and ventilation modes on the anesthesia device. The most commonly used ventilation modes during anesthesia are volume controlled (VCV) and pressure controlled (PCV). In pressure-controlled ventilation, ventilation is provided with the airway pressure determined by the anesthesiologist throughout inspiration. While the pressure is constant during inspiration, the tidal volume is variable. In volume controlled ventilation, ventilation executed at the volume is set by the anesthesiologist. In other words, the determined volume is constant, but airway pressures vary. In pediatric anesthesia practice modes have not been shown to have a clear advantage over each other. Both modes have advantages and disadvantages. With the development of modern anesthesia devices in recent years, safe ventilation can be provided even in very young children with volume controlled mode (VCV). Atelectasis is the restriction of gas exchange due to complete or partial collapse of the lung. Atelectasis can be seen in 90 percent of patients receiving general anesthesia. This incidence is reported to be 68-100 percent in children. Lung ultrasonography is an imaging method with many advantages for imaging lung-related diseases, such as not containing ionizing radiation, being inexpensive, and being performed at the bedside. Recently, its use by anesthesiologists has become widespread in many lung pathologies, including atelectasis. Traditional and modified lung ultrasonography scoring systems can be used to evaluate atelectasis in lung parenchyma with ultrasonography. In addition to the traditional system, modified scoring system also enables to evaluate small subpleural consolidations In this study, it was aimed to compare the effects of volume controlled and pressure controlled ventilation modes used in general anesthesia in children on atelectasis with lung ultrasonography.
This study will use lung ultrasounds (LUS) to evaluate the incidence and severity of intraoperative atelectasis in anesthetized children undergoing minor surgery using a laryngeal mask airway. The children will be randomly assigned to be left in spontaneous ventilation with a Positive End Expiratory Pressure (PEEP) of 5cmH2O or to be ventilated with a pressure support mode.
The goal of this clincal trial is to determine the differences in few parameter of lung function (ie Forced Vital Capacity (FCV)) between Sugammadex and conventional reversal in laparoscopic abdominal surgery. The main questions it aims to answer are: 1. Is there differences in the pulmonary function test preoperative and post extubation between Sugammadex and conventional reversal in laparoscopic abdominal surgery? 2. Is there differences in the size of atelectasis area between Sugammadex and conventional reversal in laparoscopic abdominal surgery? 3. Is there differences between sugammadex and conventional reversal in postoperative mean length of stay in laparoscopic abdominal surgery? Participants will be asked 1. to do baseline spirometry before operation 2. to be examined for lung ultrasound before operation 3. to be given either sugammadex or neostigmine as reversal after operation is completed 4. to repeat spirometry after operation for few times 5. to be examined for lung ultrasound after operation Researcher will compare sugammadex group and conventional group to see if any difference in term of lung function, size of atelectasis and length of stay.
Atelectasis after induction of general anesthesia is common even in healthy patients and is clinically problematic, especially in obese patients. We aim to investigate whether preoxygenation with high-flow nasal oxygen during anesthesia induction reduces atelectasis in obese patients.
Atelectasis is a common complication in patients undergoing surgery under general anesthesia, particularly in obese patients. Postoperative atelectasis could last for more than 24h and contribute to a variety of other complications, including hypoxemia and pneumonia. We plan to conduct a single-center, randomized controlled trial in patients undergoing bariatric surgery to test the hypothesis that driving pressure guided PEEP could reduce the postoperative atelectasis.
This study will investigate the distribution of gas during mechanical ventilation in patients undergoing robot assisted laparoscopic prostatectomy. The gas distribution of ventilation are monitored and data extracted using electric impedance tomography in different respiratory rates.
Single Use Flexible bronchoscopes have gained popularity in recent years and are becoming technologically more advanced. They are widely accepted and used in everyday practice for simple procedures. The aim of this study is to evaluate single use flexible bronchoscopes in more advanced settings, such as interventional pulmonary procedures.
Following orthoptopic heart transplantation (OHT), children undergo surveillance cardiac catheterizations to assess for signs of rejection including muscle biopsy as well as pressure measurements to guide post transplant treatment regiments. These procedures are done under general anesthesia which promotes lung tissue collapse (atelectasis). What is not known is the effect of atelectasis on intracardiac pressures which are a critical area of monitoring post-transplant patients for rejection.
The aim of this study is to evaluate the effectiveness of intraoperative individualized positive end-expiratory pressure (PEEPIND) titration, compared to fixed positive end-expiratory pressure of 5 cmH2O, on oxygenation, hemodynamic variables, and early postoperative complications in obese patients undergoing laparoscopic bariatric surgery.
The aim of this study is to evaluate the role of nitric oxide on pulmonary vasculature and right ventricular function in postoperative cardiac surgery patients.
