Abstract

Objective:Application of Laryngeal Mask Airway (LMA) as a ventilation method has been rarely explored in short and medium period orthopedic operations. In this study, we evaluated ventilatory efficacy of LMA in patients admitted to Ho Chi Minh City Orthopedic and Rehabilitation Hospital, Vietnam via a number of patient indicators including changes of pulse, blood pressure, airway pressure, SpO2 and pressure of CO2 at the end of an exhaled breath (EtCO2). Method: A total of 154 emergency and elective surgery cases with anesthesia were selected for the study. Result: One minute after LMA insertion to discontinuation of anesthetic, we recorded slower pulse of patients but only twenty-six cases (16.9%) required intravenous administration of atropine. Blood pressure of patients dropped after 1 minute following LMA insertion but then recovered afterward and only nine cases (5.8%) needed administration of ephedrine. Conclusion: After surgery, only eleven (7.15%) patients experienced oral mucosal bleeding but no further special treatment was used.

喉罩通气道 (LMA) 在中短期创伤性骨科手术中的应用

目的：喉罩通气道（LMA）作为一种通气方法在中短期骨科手术中的应用还很少被探讨。在本研究中，我们通过一系列患者指标，包括脉搏、血压、气道压力、SpO2 和呼气末二氧化碳压力（EtCO2）的变化，评估了越南胡志明市骨科和康复医院住院患者使用 LMA 的通气效果。方法：研究共选取了 154 例进行麻醉的急诊和择期手术病例。结果插入 LMA 1 分钟后至停止麻醉前，我们记录到患者脉搏减慢，但只有 26 例（16.9%）患者需要静脉注射阿托品。患者的血压在插入 LMA 1 分钟后下降，但随后恢复，只有 9 例患者（5.8%）需要使用麻黄碱。结论：手术后，仅有 11 例（7.15%）患者出现口腔黏膜出血，但未采取进一步的特殊治疗。孟加拉国医学科学杂志》第 23 卷第 01 期 January'24 Page : 207-213
