UNASSIGNED: The study included 63 subjects with mild/moderate PBC neck of either sex with American Society of Anesthesiologists Physical Status I and II under GA. Patients with intraoral pathology, mouth opening <2.5 cm, and severe contracture were excluded. Patients were randomly assigned to i-gel® (I) and BlockBuster™ (B) groups. The primary objective of the study was the time for successful insertion. First attempt success rate, oropharyngeal leak pressures (OLP), and complications were also assessed.
UNASSIGNED: Mean insertion time was significantly less in Group I as compared to Group B (17.35 ± 1.43 vs. 21.32 ± 1.10 s; P < 0.001), OLP in Group B was significantly higher as compared to Group I (34.03 ± 1.33 vs. 25.23 ± 3.04 cm of H2O; P < 0.001). Group I was found to be statistically easier to insert as compared to Group B (P = 0.011) with reduced requirement of airway maneuvering to insert the device (P = 0.017). Groups were similar in terms of complications.
UNASSIGNED: SGDs are attractive option for airway management in mild/moderate degree of PBC neck. i-gel® having shorter insertion time with easier insertion can be favorable at times of emergency while use of LMA BlockBuster™ can be preferred to reduce the risk of aspiration owing to higher OLP.
■该研究包括63名受试者,其性别为轻度/中度PBC颈部,美国麻醉医师协会在GA下的体质状态I和II。患者口内病理,张口<2.5厘米,排除重度挛缩。患者被随机分配到i-gel®(I)和BlockBuster™(B)组。研究的主要目的是成功插入的时间。第一次尝试成功率,口咽渗漏压(OLP),并对并发症进行了评估.
■与B组相比,I组的平均插入时间明显少于B组(17.35±1.43vs.21.32±1.10s;P<0.001),B组的OLP明显高于I组(34.03±1.33vs.25.23±3.04cm的H2O;P<0.001)。发现与B组(P=0.011)相比,I组在统计学上更容易插入,并且降低了对插入装置的气道操纵的需求(P=0.017)。各组在并发症方面相似。
■SGD是轻度/中度PBC颈部气道管理的有吸引力的选择。具有较短的插入时间和较容易插入的i-gel®在紧急情况下可以是有利的,而使用LMABlockBuster™可以是优选的,以降低由于较高的OLP引起的抽吸风险。
