Hemodynamic and catecholamine stress responses to insertion of the Combitube, laryngeal mask airway or tracheal intubation

摘要: UNLABELLED In a prospective, randomized, and controlled trial, we compared the stress responses after insertion of Combitube (CT; Kendall-Sheridan Catheter Corp., Argyle, NY), laryngeal mask airway (LMA), or endotracheal intubation (ET). Seventy-five patients scheduled for routine urological gynecological surgery were randomly allocated to one three groups ventilated via either an ET, LMA, CT. All devices could be inserted easily rapidly, providing adequate ventilation oxygenation. Insertion CT was associated with significant increase in mean maximal systolic arterial pressure (160+/-32 mm Hg) diastolic (91+/-17 ET (140+/-24, 78+/-11 Hg; P < 0.05, 0.01, respectively) LMA (115+/-33,63+/-22 Hg, both 0.001). The epinephrine norepinephrine plasma concentrations (37.3+/-31.1 279+/-139 pg/mL, significantly higher than those (35.8+/-89.8 195+/-58 (17.3+/-13.3 158+/-67 respectively). This might attributed pharyngeal cuff on anterior wall. We conclude that causes pronounced response precautions should taken when used at risk hypertensive bleeding. IMPLICATIONS this study, showed hemodynamic catecholamine (Kendall-Sheridan NY) intubation. increased may represent serious hazard cardiovascular disease.
