Supraglottic airway devices such as the ProSeal Laryngeal Mask Airway (PLMA) and Laryngeal Tube-Suction Airway (LTS) that provoke the least stress responses could be beneficial in many situations, especially in patients with cardiovascular disease. We compared the haemodynamic and catecholamine stress response of the LTS and PLMA in a randomised study of 36 patients. Mean arterial pressure, heart rate, epinephrine and norepinephrine levels were all reduced following induction of anaesthesia with no significant differences between the two groups. Following insertion of LTS, mean arterial pressure, heart rate, epinephrine and norepinephrine levels increased to pre-induction levels. However, following the insertion of the PLMA, mean arterial pressure, heart rate, epinephrine and norepinephrine levels remained significantly lower than pre-induction values. Mean arterial pressure, heart rate and epinephrine were significantly greater in the LTS group than in the PLMA group. We conclude that the LTS produces a greater and more sustained haemodynamic and catecholamine stress response than does the PLMA.
诸如食管引流型喉罩通气道（PLMA）和喉管吸引通气道（LTS）等引起应激反应最小的声门上气道装置在许多情况下可能是有益的，尤其是在患有心血管疾病的患者中。我们在一项对36例患者的随机研究中比较了LTS和PLMA的血流动力学及儿茶酚胺应激反应。麻醉诱导后平均动脉压、心率、肾上腺素和去甲肾上腺素水平均降低，两组之间无显著差异。插入LTS后，平均动脉压、心率、肾上腺素和去甲肾上腺素水平升至诱导前水平。然而，插入PLMA后，平均动脉压、心率、肾上腺素和去甲肾上腺素水平仍显著低于诱导前值。LTS组的平均动脉压、心率和肾上腺素显著高于PLMA组。我们得出结论，与PLMA相比，LTS产生的血流动力学和儿茶酚胺应激反应更大且更持久。
