Can 10 Seconds Inspiratory Hold Open Atelectasis in Mechanically Ventilated Patients?

Atelectasis

This study evaluates whether sustaining inspiratory pressure for 10 seconds at a time can open collapsed lung areas in non-dependant regions of the lung in mechanically ventilated patients.

Comparison of Three Scores for Ultrasound Assessment and Monitoring of Pulmonary Aeration

AtelectasisPneumonia4 more

This study is designed to compare three ultrasound-based aeration scores that were previously validated in specific populations, and to assess their correlation with computed tomographic measurement of pulmonary aeration in a population with different pathologies. Hypothesis: The "Loss of Aeration Score" will be more accurate than a simplified version and another widely used score, the "Lung Ultrasound Score".

Determination of Best PEEP (Positive End-expiratory Pressure) in Anesthetized Infants in Terms of...

Pediatric Surgery

Purpose of research; to determine the appropriate positive end-expiratory pressure to minimize atelectasis during general anesthesia in infants. Study design : Application of one pressure of PEEP among 3, 6, or 9 cmH2O during mechanical positive ventilation for general anesthesia to randomly assigned infants over 6 months to 13 months of age . Immediately after the start of anesthesia (PEEP=0) and before the end of anesthesia, the score of atelectasis is measured by lung ultrasonography with the standardized method. The scores at PEEP3, PEEP6, and PEEP9 will be compared to identify the appropriate PEEP at which atelectasis is the least likely to occur during anesthesia. Medical Equipment : Ultrasonography with 6 - 13 MHz linear probe, Cardio-Q esophageal Doppler The number of target subjects: According to the results of previous studies, the lung ultrasound score by ultrasonography at the end of anesthesia was 28.5 (IQR 21.8-37) without any recruitment (PEEP 0 cmH2O) (IQR 6-21.3). When PEEP of 5 cmH2O was maintained, the lung ultrasound score is 12.5 (IQR 6-21.3), which is lower than PEEP 0. It is assumed that the score at PEEP3 is 20, the score at optimal PEEP is 10, and the standard deviation is 11. Bonferroni correction is required for statistical analysis. In comparison between the two groups, alpha is used as the Bonferroni corrected alpha level of 0.05 / 3 = 0.017. The significance level alpha is fixed at 0.017 and the number of samples considering the 10% dropout rate when the power (1-β) is 80% is required to be 30 for each group. Data analysis and statistical methods: Atelectasis score, cardiac index, peak inspiratory pressure, and dynamic compliance will be compared by t-test between groups(PEEP3 vs PEEP 6, PEEP 3 vs PEEP 9, PEEP 6 vs PEEP 9). P < 0.017 is going to be considered statistically significant.

Peroperative Use of Positive End-expiratory Pressure Prevents Formation of Atelectasis as Studied...

Atelectasis

Atelectasis is common during and after general anaesthesia and a number of interventions have been suggested in order to prevent their formation. The use of Positive End Expiratory Pressure (PEEP) during general anaesthesia has in recent years been questioned. The investigators hypothesize that the use of PEEP as a single intervention improves oxygenation and prevents atelectasis as investigated by computed tomography compared to a control group with zero PEEP.

AtelectasisAcquired Brain Injury1 more

Investigators conduced in the Neurological Rehabilitation Unit of the IRCCS "S.Maria Nascente - Fondazione Don Gnocchi", (Milan) a retrospective study on 19 patients hospitalized between September 2018 and February 2021, with the aim of comparing the efficacy of the two devices, MetaNeb® and Intrapulmonary Percussion Ventilation (IPV®). The efficacy was evaluated considering the change of various measures after two weeks of treatment. The main outcome considered is the atelectasis score, assigned by two radiologists who blindly and retrospectively evaluated it on high-resolution computed tomography (HRTC) images

Predictive Value of Ariscat Index In The Development of Pulmonary Complication After Major Abdominal...

Postoperative ComplicationsCancer4 more

The term postoperative pulmonary complication is the development of any complications affecting the respiratory system after anesthetic and surgery procedures. The ARISCAT risk assessment score is a seven-variable regression model that divides patients into low, moderate, and high-risk groups. In this study, the investigators aimed to investigate the effectiveness of the ARISCAT risk scoring index in predicting postoperative pulmonary complication development in patients scheduled for major abdominal cancer surgery.

Anesthesia

This study investigates under controlled conditions the variation of poorly ventilated lung units (silent spaces) in children between 1 and 6 years of age measured by electrical impedance tomography during intravenous anaesthesia in a day-hospital setting and before discharge to help further raise safety standards in paediatric anaesthesia

Which Ventilatory Strategy is Better for Lung in Upper Abdominal Surgeries?

Anesthesia Induced Atelectasis

Ventilated Patients especially those undergoing upper abdominal surgeries are prone to lung atelectasis. They are at risk of adverse effects secondary to inadequate lung ventilation. Applied PEEP and Recruitment maneuver are thought to enhance lung aeration under general anesthesia which could be assessed by ultrasound.
