目的：探讨超声监测下定位定量洗胃方法的应用价值。方法选取205例急性口服药物中毒患者，随机分为对照组（101例）和实验组（104例）。对照组采用传统方法（盲插胃管和电动洗胃机）确定灌洗量后进行洗胃；实验组在对照组的基础上应用超声监测胃管插入深度后进行定位，观察洗胃进出液量进行定量洗胃，比较两组洗胃并发症的发生率及洗胃效果。结果实验组并发症发生率显著低于对照组（P<0.05），洗胃效果显著优于对照组（P<0.05）。结论超声监测下定位定量洗胃能有效降低洗胃并发症的发生率，提高洗胃效果。%Objective To investigate the application value of locating and quantitative gastrolavage under ultrasound monitoring.Methods 205 cases of patients with acute oral drug poisoning were selected and randomly divided into control group (n=101) and experimental group (n=104). Traditional method of gastric intubation, including blind gastric tube insertion and electric gastric lavage, was applied to the patients in the control group; gastric lavage would be conducted after the amount of lavage was determined. For patients in the experimental group, gastric tube insertion was inserted under ultrasound monitoring to determine insertion depth and then to locate the position of the tube; quantitative gastric lavage was carried out based on the monitoring of the intake and output of lfuid volume during gastric lavage. Then the complication rate and effectiveness of gastric lavage in the two groups were compared. Result The complication rate of the experimental group was lower than the control group (P<0.05). The effectiveness of gastric lavage in the experimental group was signiifcantly better than the effect of the traditional gastric lavage in the control group (P<0.05).Conclusion Locating and quantitative gastric lavage under ultrasound monitoring could effectively reduce the complication rate of gastric lavage and improve the effectiveness of gastrolavage.
