摘要

摘要在某些医疗病例中,在全麻期间提供安全的气道管理可能会有问题,尤其是当由于胃内压增加而存在胃内容物反流和误吸的风险时。目前的研究旨在测试两种类型的LMA在几种动物中的适用性,并将其与气管插管方法在确保密封气道呼吸方面的有效性进行比较,作为使用气管插管的替代方法。这项研究在狗(n=33)、猫(n=9)、猪(n=9。每种动物都使用一种或两种类型的喉罩:LMA Classic™-cLMA和LMA ProSeal™-PLMA。通过确定插入技术、首次尝试插入和错位的可能性、对各种动物物种的依从性、通气时间、袖带压力和密封能力来评估每个喉罩。狗的LMA尺寸兼容性最高(23,87±14,30 kg),6只受试者的尺寸为3,特强受试者为4;猪(43,22±12.32kg),4号;在兔子(3.84±0.36kg)中,尺寸为-1;3号和4号绵羊(48.29±4.65kg)。通气时间猪和马鹿最高(分别为121,11±42,85分钟和300,00分钟),猫最低(28,33±16,96分钟)。首次尝试LMA插入的成功率在兔子中最低(60%),在绵羊和鹿中最高(100%)。错位率最高的是兔子(40%),最低的是猫、羊和鹿(0%)。胃反流最常见于绵羊(71.4%)和鱼子(100%)。LMA在兽医麻醉实践中的使用显著改善了全身麻醉期间动物的气道管理。膨胀的LMA袖带并不妨碍其处置。因此,排水管和呼吸管都必须固定。在兔子中使用LMA与更高的错位和其他并发症发生率相关。我们的研究结果表明,为人类设计的LMA可以用于兽医的气道管理。

Usage of Laryngeal Mask Airway Devices in Veterinary Medicine
Abstract Providing a secure airway management during general anesthesia could be problematic in some medical cases, especially when there is a risk of regurgitation and aspiration of the gastric content due to increased intragastric pressure. The current study aimed to test the applicability of two types of LMA in several animal species and to compare its effectiveness to the endotracheal intubation method in securing sealed airway respiration as an alternative to using endotracheal tubes. The study was conducted in dogs (n=33), cats (n=9), swine (n=9), rabbits (n=5), sheep (n=7) and roe deer (n=1). One or both types of laryngeal masks were used for each animal species: LMA Classic™-cLMA and LMA ProSeal™-PLMA. The assessment of each laryngeal mask was performed by determining the insertion technique, the possibilities of first-attempt insertion and malposition, the compliance with various animal species, ventilation time, cuff pressure, and sealing capacity. The highest LMA size compatility in dogs (23,87±14,30 kg) was size-3 in six and size-4 in forteen subjects; In swine (43,22±12,32 kg), size-4; In rabbits (3,84±0,36 kg) size-1; and in sheep (48,29±4,65 kg) size-3 and size-4. Ventilation time was highest in swine and roe deer (121,11±42,85 min and 300,00 min, respectively) and lowest in cat (28,33±16,96 min). First-attempt LMA insertion success was lowest in rabbits (60%), and highest in sheep and roe deer (100%). Malposition was with highest rate in rabbits (40%) and lowest in cat, sheep and roe deer (0%). Gastric reflux was most frequently observed in sheep (71,4%) and roe deer (100%). The usage of LMA in the veterinary anesthetic practice significantly improves airway management in animals during general anesthesia. The inflated LMA cuff does not prevent its disposition. Therefore, both the drain and respiratory tubes must be fixed. The usage of LMA in rabbits was associated with higher incidence of malposition and other complications. Our findings suggest that LMA designed for humans can be used for airway management in veterinary medicine.
