Ventilator Lung Clinical Trial
Official title:
Pressure Support Ventilation Versus Continuous Positive Air Way Pressure (CPAP) Using I Gel Laryngeal Mask for Minor Surgery in Adult Patients, a Prospective cross_over Study
Introduction of Supra glottic airway devices (SAD) has revolutionized the airway management. The first successful supraglottic airway device, the Laryngeal Mask Airway(LMA).The various other SADs include ProSeal LMA, Intubating LMA and i-gel to overcome the limitations of classic Laryngeal Mask Airway( c-LMA) The risk of aspiration with c-LMA is reported tobe around 9% , pleaseboth the c-LMA and PLMA have cuff related complications. High cuff pressure in laryngeal mask airways can cause damage to the mucosae on periglottic and supraglottic structures . Therefore, to overcome the limitations of Pro Seal Laryngeal Mask Airway (PLMA )a new and cheaper SAD called i-gel was developed. i-gel is a novel and innovative, latex free supraglottic device, made up of medical grade thermoplastic elastomer, which is soft, gel like, transparent The number of manipulations required are more in PLMA than i gel resulting in hemodynamic changes .The i-gel is comparable to PLMA insuring the airway during controlled ventilation. It is better than PLMA in terms of ease of insertion. Spontaneous breathing is the most popular mode of ventilation with the laryngeal mask airway (LMA), but it provides less effective gas exchange than does positive pressure ventilation (PPV) . The patients receiving sevoflurane anesthesia with unassisted ventilation have a reduced rib cage contribution to ventilation, decreased tidal volume, and respiratory rate . Pressure support ventilation (PSV) is a ventilator mode that is initiated by the patient and synchronized with the patient's respiratory effort. And may improve gaseous exchange in patients. In the intensive care unit, it is often considered the preferred mode for weaning mechanical ventilation .PSV provides more effective gas exchange than does unassisted ventilation with CPAP during anesthesia with the LMA while preserving hemodynamic homeostasis. The use of PSV versus CPAP with the Pro Seal laryngeal mask airway in anesthetized pediatric patients revealed that PSV improved gaseous exchange and reduced work of breathing during general anesthesia PSV via Pro- Seal laryngeal mask airway improves gaseous exchange and ventilation in pediatric patients under general anesthesia more than spontaneous ventilation .
