VALUE OF Ⅰ-GEL VERSUS LARYNGEAL MASK AIRWAY PROSEAL FOR GASTROINTESTINAL SURGERY IN ELDERLY PATIENTS
Objective To compare the clinical values of I-gel and laryngeal mask airway ProSeal (LMA-P) for gastrointestinal surgery in elderly patients.Methods Sixty elderly patients (ASA Ⅰ-Ⅲ),who underwent selective gastrointestinal surgery under general anesthesia,were randomly assigned to Ⅰ-gel group and LMA-P group,with 30 patients in each group.After induction of anesthesia,the Ⅰ-gel or LMA-P was inserted.The insertion time and insertion success rate on the first attempt,as well as fiberoptic bronchoscope (FOB) score,were recorded.The blood oxygen saturation (SpO2),end tidal partial pressure of carbon dioxide (PetCO2) and partial pressure of carbon dioxide (PaCO2) were periodically recorded during surgery.The incidence of airway leakage and gastric inflation during surgery,regurgitation and aspiration,blood staining on the device,and sore throat after device removal were also assessed.Results The Ⅰ-gel group showed a significantly shorter mean insertion time (t =12.865,P＜ 0.05) and significantly lower incidence rates of airway leakage and gastric inflation (x2 =7.925,P＜0.05) compared with the LMA-P group.There were no significant differences in the insertion success rate on the first attempt,FOB score,and incidence of blood staining on the device and sore throat between the two groups (P＞0.05).The SpO2,PetCO2,and PaCO2 during ventilation were all within the normal range,and did not differ between the two groups (P＞0.05).Conclusion Both Ⅰ-gel and LMA-P can be used for airway management in elderly patients undergoing gastrointestinal surgery under general anesthesia.Moreover,the Ⅰ-gel has advantages over the LMA-P in terms of shorter insertion time,better airway sealing,and lower incidence of airway leakage and gastric inflation,which is more beneficial to airway management and control in anesthesia.
