Effect of double tube laryngeal mask on respiratory and circulatory function in elderly patients undergoing upper abdominal laparoscopic surgery
Objective To evaluate the effects of LAM-Supreme on perioperative respiratory and circulatory function in elderly patients undergoing upper abdominal laparoscopic surgery.Methods Sixty-two elderly patients with upper abdominal laparoscopic surgery under elec-tive general anesthesia,aged 65～75 years old,gender unlimited,ASA grade II to III.Random number table method was used to divide 33 ca-ses into laryngeal mask group(group L)and 29 cases into tracheal intubation group(group E).The hemodynamics,respiratory parameters and postoperative recovery of the two groups were compared and analyzed.Results There were no statistically significant differences in MAP and HR between the 2 groups before anesthesia induction(T0)(P＞0.05),but HR and MAP in group L immediately after catheterization(laryn-geal mask)(T1)and immediately after tracheal catheter removal(laryngeal mask)(T3)were lower than those in group E(P＜0.05).There was no statistical significance in PaO2/FiO2 between the 2 groups at different time points(P＞0.05),PETCO2 at T2 and T3 was higher than T1,and PaO2/FiO2 was lower than T1 in the 2 groups,with statistical significance(P＜0.05).PETCO2 in group E at T2 and T3 was lower than that in group L,and the differences were statistically significant(P＜0.05).There was no significant difference in Ppeak,Pplat and Cdyn between the 2 groups at T1(P＞0.05),and Cdyn in D at T2 and T3 was lower than that at T1,with statistical significance(P＜0.05).At T2,Ppeak and Pplat in group E were higher than those in group L,and Cdyn was lower than that in group L,with statistical significance(P＜0.05).Ppeak and Pplat at T2 and T3 in group L were higher than those at T1,and Ppeak and Pplat at T2 in group E were higher than those at T1,with statistical signif-icance(P＜0.05).The total incidence of postoperative complications in group L was lower than that in group E,and the difference was statisti-cally significant(P＜0.05).Conclusion Compared with tracheal intubation,LAM-Supreme is more conducive to maintaining perioperative respiratory and circulatory function in elderly patients undergoing upper abdominal laparoscopic surgery under general anesthesia,and reducing the risk of postoperative complications.
