Condition: Gastric Insufflation · Sponsor: Cairo University
Gastric air insufflation during insertion of a laryngeal mask airway (LMA) is a known phenomenon and can have important clinical implications, especially in relation to: During positive pressure ventilation or improper insertion technique, air can be forced into the esophagus and stomach or LMAs do not fully seal the esophagus, so high ventilation pressures or incorrect placement may lead to gastric insufflation. Which may lead to Increased risk of regurgitation and aspiration, especially if the gastric contents reach the upper esophagus, Abdominal distension, which can reduce ventilation efficiency, nausea, vomiting, or delayed gastric emptying postoperatively which detected by Epigastric auscultation may reveal gurgling sounds during ventilation, Gastric ultrasound can visualize the extent of gastric insufflation and Capnography sometimes shows altered patterns if regurgitation begins . This complication prevented by: * Use low-pressure, controlled ventilation (\<20 cmH₂O). * Ensure proper size and positioning of the LMA. * Use second-generation LMAs (like LarySealPro or Ambu AuraGain LMA) that have gastric drainage ports to relieve air. Consider gastric ultrasound preoperatively to assess risk . (1) Several studies have assessed the performance of Ambu AuraGain and LarySeal Pro individually or in comparison with other supraglottic airway devices. Ambu AuraGain, a second-generation device with a gastric drainage channel, has demonstrated high oropharyngeal leak pressures…
