吸引型喉导管与食管引流型喉罩在腹腔镜手术麻醉中的应用

目的：探讨吸引型喉导管与食管引流型喉罩用于腹腔镜手术麻醉通气的效果。方法：择期腹腔镜胆囊切除术患者32例,随机分为吸引型喉导管组（LTS组）与食管引流型喉罩组（PLMA组）,进行麻醉中通气。结果：LTS组与PLMA组气腹前后,放气腹前后pH、PaCO2各组内与本组间比较无明显差异（P〉0.05）。PETCO2、SpO2于气腹前后无明显差异（P〉0.05）。Ppeak、VT于气腹前后差异明显（P〈0.05）,Ppeak于放气腹前后也有明显差异（P〈0.05）。结论：LTS与PLMA用于全麻腹腔镜手术通气,气腹建立时VT由8mL/kg调整为10mL/kg,可避免CO2气腹引起的PaCO2升高,通气效果可维持稳定。

Application of Laryngeal Tube Suction and Proseal Laryngeal Mask Airway for Ventilation Undergoing Laparoscopic Surgery

Objective To evaluate the effect of the laryngeal tube suction （LTS） and the proseal laryngeal mask airway （PLMA） for ventilation undergoing laparoscopic surgery. Methods Thirty-two patients undergoing laparoscopic cholecystectomy were randomly allocated to LTS group and PLMA group for ventilation under LTS or PLMA during the operation.Results No significant differences in pH,PaCO2,PETCO2,SpO2 were found in the periods of before and after pneumoperitoneum setting and after pneumoperitoneum deflation between or within groups of LTS and PLMA （P〉0.05）.Before and after pneumoperitoneum setting Ppeak and VT showed significant differences in both groups of LTS and PLMA （P〈0.05）.After pneumoperitoneum and after pneumoperitoneum deflation setting,there were significant differences from Ppeak in both groups of LTS and PLMA （P〈0.05）. Conclusion It is preferable to add 20% of volume to the regular vital volume,from 8 mL/kg before pneumoperitoneum setting to 10 mL/kg after pneumoperitoneum setting,to counter the increase of PaCO2 arroused by artificial pneumoperitoneum and thus ensuring the stability of ventilation.
