目的:探讨经喉罩吸入麻醉在小儿短小手术中的应用。方法:Ⅰ组25例吸入七氟醚和笑气,置入喉罩后手控呼吸。Ⅱ组25例采用异丙酚[2~8 mg/(kg.h)]和氯胺酮[1~2 mg/(kg.h)]持续泵注,吸氧2~3 L/min、自主呼吸,比较两组疗效。结果:两组患儿在诱导前、切皮、术中和术毕MAP、HR和PONV发生率无统计学差异。Ⅰ组肢体活动0例,SpO2(95%2例(8%)。Ⅱ组肢体活9例(36%),SpO2(95%7例(28%),明显高于Ⅰ组(P<0.05)。结论:喉罩吸入麻醉安全、可靠,可在小儿短小手术中推广应用。
Objective: To investigate the application of inhalation anesthesia via laryngeal mask in pediatric short operation. Methods: Twenty-five patients in group Ⅰ inhaled sevoflurane and nitrous oxide gas and placed them into the laryngeal mask for manual respiration. In group Ⅱ, 25 patients were continuously infused with propofol [2-8 mg / (kg · h)] and ketamine [1-2 mg / (kg · h)] for 2 ~ 3 L / min, Compare the two groups curative effect. Results: There was no significant difference in the incidence of MAP, HR and PONV between the two groups before incision, incision, intraoperative and postoperative. SpO2 was 95% in 2 cases (8%) in group Ⅰ, 9 cases (36%) in group Ⅱ and 95% in 7 cases (28%), which was significantly higher than that in group Ⅰ (P <0.05) Conclusion: Laryngeal mask inhalation anesthesia is safe and reliable, which can be widely applied in short pediatric surgery.
