It is more difficult to perform bag-mask ventilation in edentulous patients than in patients with intact dentition. The laryngeal mask airway (LMA) provides a better alternative to the standard face mask if the facial contours of the patient are not suited for the standard face mask. We aimed to compare these two different LMAs in edentulous geriatric patients.
Edentulous patients aged ≥65 years of American Society of Anesthesiologists physical status I-III were included in the study. They were randomly assigned to Supreme group (n=30) and Unique group (n=30). Success of first insertion attempt, ease and time of insertion and oropharyngeal leak pressure were recorded.
The success rate of the first insertion attempt was higher in the Supreme group than in the Unique group (86.6 and 73.3%, respectively; p=0.04). Time of insertion was similar (10.04 s and 11.87 s, respectively) and insertion was easy in 90% and 100% of patients, respectively. Oropharyngeal leak pressures were measured as 20.56-cm H2O and 17.10-cm H2O for LMA Supreme™ and LMA Unique™, respectively.
The efficacy and safety in both groups were comparable in edentulous geriatric patients during short surgical procedures. Even the success rate of insertion with both was lower than that mentioned in the literature; the success of insertion at the first attempt was superior with the LMA Supreme™ in our edentulous study group.
与牙列完整的患者相比，无牙患者进行面罩通气更为困难。如果患者的面部轮廓不适合标准面罩，喉罩气道（LMA）可作为标准面罩的更好替代方案。我们旨在比较这两种不同的LMA在无牙老年患者中的应用情况。
纳入年龄≥65岁、美国麻醉医师协会身体状况分级为I - III级的无牙患者。他们被随机分为至尊组（n = 30）和独特组（n = 30）。记录首次插入尝试的成功率、插入的难易程度和时间以及口咽漏气压。
至尊组首次插入尝试的成功率高于独特组（分别为86.6%和73.3%；p = 0.04）。插入时间相似（分别为10.04秒和11.87秒），且分别有90%和100%的患者插入操作容易。至尊LMA™和独特LMA™的口咽漏气压分别测得为20.56厘米水柱和17.10厘米水柱。
在短小手术过程中，两组在无牙老年患者中的有效性和安全性相当。尽管两者的插入成功率均低于文献中提及的成功率，但在我们的无牙研究组中，至尊LMA™首次插入的成功率更高。
