面罩预吸氧联合深呼吸对无痛胃镜检查中低氧血症的预防作用(1)
摘要:目的 探讨麻醉给药前面罩预吸氧+深呼吸对无痛胃镜检查中低氧血症的预防作用。方法 200例无痛胃镜检查者,按随机数字分为实验组(S)和对照组(D),每组100例。实验组麻醉给药前面罩深呼吸纯氧2 min,氧流量8 L/min。对照组自然呼吸。两组在给药后检查中均面罩盖住鼻部吸纯氧。均采用丙泊酚与芬太尼复合麻醉,记录受检者术前、预吸氧后、胃镜检查2 min、结束时、苏醒后血氧饱和度(SpO2)和呼吸(RR)。结果 两组患者麻醉后SpO2均有所下降,但预吸氧组SpO2 绝大多数在正常水平,低于93%很少。对照组SpO2<90%明显高于实验组,差异有统计学意义(P<0.05)。结论 面罩深呼吸给氧能有效的预防无痛胃镜检查术中低氧血症的发生,提高患者的安全性。

Abstract:Objective To investigate the preventive effect of the pre - oxygen inhalation and deep breathing on the front cover of anesthesia for painless gastroscopy in patients with painless gastroscopy.Methods 200 cases of painless gastroscopy, were randomly divided into experimental group (s) and control group (d), 100 cases in each group. Experiment group, the anesthesia to front of the medicine cover deep breathing pure oxygen for 2 minutes, oxygen flow 8L/min. control group with spontaneous breathing. Two groups to check after the drug was the cover surface live nasal inhalation of oxygen in the propofol and fentanyl anesthesia recorded examination before operation, following preoxygenation, gastroscopy for 2 minutes, at the end of after waking oxygen saturation (SpO2), respiratory rate (RR).Results The two groups of patients after anesthesia SPO2 all decreased, but the majority of the pre oxygen group SPO2 in the normal level, less than 93%. The control group SPO2 < 90% was significantly higher than the experimental group, the difference was statistically significant (P<0.05).Conclusion Oxygen inhalation can effectively prevent the occurrence of low oxygen and improve the safety of patients during painless gastroscopy.

胃鏡检查是当前诊断和治疗上消化道疾病的一个重要手段,然而许多患者对此项检查都有一种恐惧感而难以接受,特别是咽喉反射敏感的患者,更难以忍受而不能完成检查。因此无痛胃镜因提高了患者的舒适度受到了患者的广泛欢迎。但因胃镜检查与麻醉共用呼吸道,而抑制咽喉反射引起的呛咳所需的麻醉深度要深,因而所用麻醉药量要大,而麻醉药物有剂量依耐性呼吸抑制作用[1],导致检查过程中易发生下颌松驰,呼吸暂停,呼吸抑制,增大了麻醉风险。基层医院往往由麻醉医生一个人注药、给氧,观察生命体征,操作上有一定的困难,也存在安全隐患。怎样提高无痛胃镜检查的安全性,有效的预防低氧血症的发生,是麻醉医师共同关心的问题。作者采用面罩深呼吸预先给氧的方法对100例患者实施无痛胃镜检查术。报道如下:

1.1一般资料 200例行无痛胃镜检查者,ASA1-Ⅱ级,无药物过敏史,无急性上消化道出血,严重心肺疾病,上呼吸道感染者,丙泊酚使用禁忌者等。
1.2 麻醉方法 麻醉前按胃镜检查要求准备,入室后建立静脉通道,监生命体征(SpO2,心率,血压,心电图,呼吸等)。取左侧卧位,实验组置入咬口器后,麻醉机面罩给氧,由患者按住面罩,嘱其深呼吸2 min,氧流量8 L/min,对照组自然呼吸,由同一位胃镜医师行胃镜检查,同一位麻醉师给药。静注芬太尼0.05mg 1 min后,静注丙泊酚1.5~2.5 mg/mg 30~60 s注完。待睫毛反射和吞咽动作消失,肌肉松驰,行胃镜检查,根据胃镜检查时间和患者的体动反应,追加丙泊酚20~30 mg,根据血压及心率静注麻黄碱及阿托品。两组患者麻醉后均面罩盖住鼻部给氧,SpO2<90%给予加压给氧辅助呼吸。两组患者在性别、年龄、体重等方面差异无统计学意义(P>0.05)。, http://www.100md.com(黄芳)
