目的探讨内窥镜面罩在老年煤工尘肺患者无痛苦胃镜中的可行性。方法选择老年煤工尘肺患者60例,分为内窥镜面罩吸氧组30例(A组),双腔鼻导管吸氧组30例(B组),两组均行丙泊酚静脉麻醉,测定检查前、检查中、苏醒后的MAP、HR、SpO2的变化情况,计算检查时间及总用药量。结果检查中MAP、HR的变化两组相比差异无统计学意义(t=1.38,P>0.05);A组和B组检查中SpO2变化差异有统计学意义(t=2.81,P<0.01),与检查前比较SpO2变化差异有统计学意义(t=2.033,P<0.05);苏醒后MAP、HR、SpO2组间及组内相比差异均无统计学意义(t=1.52,P>0.05)。由于B组患者检查过程中出现呼吸抑制,需暂停检查,经处理后方可继续,导致B组患者检查时间长于A组(t=2.26,P<0.05)。结论老年煤工尘肺患者行无痛胃镜时使用内窥镜面罩安全可靠。
Objective To explore the feasibility of endoscopic masks in painless endoscopy of elderly coal workers with pneumoconiosis. Methods Sixty elderly patients with coal pneumoconiosis were selected and divided into 30 cases (group A) with oxygen inhalation of endoscope and 30 patients with oxygen inhalation (group B) with double-lumen nasal cannula. Both groups received propofol anesthesia, Before and after the test, check the changes of MAP, HR and SpO2 after waking up, and calculate the examination time and the total dosage. Results There was no significant difference between the two groups in the changes of MAP and HR (t = 1.38, P> 0.05). The difference of SpO2 in group A and group B was statistically significant (t = 2.81, P <0.01) (T = 2.033, P <0.05). There was no significant difference in the changes of SpO2 between the groups of MAP, HR and SpO2 after waking up (t = 1.52, P> 0.05) ). Patients in group B had longer duration of examination than those in group A (t = 2.26, P <0.05) due to respiratory depression during examination. Conclusion Elderly coal workers pneumoconiosis patients with painless gastroscopy endoscope mask safe and reliable.
