Abstract:

Objective: To compare the ventilatory effects of the three-way laryngeal mask airway (TLMA) and tracheal tube (TT) on hemodynamics, respiratory function, and stress responses in a canine model during bronchoalveolar lavage (BAL). Study Design: Experimental study. Place and Duration of Study: The 303rd Hospital of the Chinese People's Liberation Army in May 2013. Methodology: Sixteen dogs were divided into two groups. MAP, SpO2 and HR were recorded before anesthesia (T0), immediately before intubation (T1), during intubation (T2), at 3 (T3) and 10 (T4) minutes after mechanical ventilation, at 10 (T5), 20 (T6), and 30 (T7) minutes during the course of BAL, during extubation (T8), and 3 minutes after extubation (T9). Tidal volume, peak inspiratory airway pressure, and expiratory CO2 pressure were recorded at time points T2, T5, T6, T7, and T8. Stress responses variables, including epinephrine and norepinephrine levels, were examined at time points T0, T2, T3, T5, T8, and T9. Results: BAL was successfully completed in all animals. In comparison to the TT, the TLMA was capable of maintaining hemodynamic stability and ventilation (p < 0.05), and producing less stress responses (p < 0.05). Conclusion: In a canine model, ventilation with the TLMA was better than the TT during BAL in terms of maintaining effective ventilation and stable hemodynamics, and producing less stress responses.
