目的了解正常成人下腹壁厚度,并探讨其相关因素及其对根据指南针原理设计的排尿报警装置的意义。方法应用B超连续测量l00例成人的下腹壁及其浅层和深层的厚度,膀胱的前后径、上下径及左右径,并测量身高、体质量、测量点到脐部的距离,计算体质量指数(BMI)和膀胱容量,分析影响下腹壁厚度的相关因素。结果本组成人的下腹壁厚度(23.4±6.6)mm,95%可信区间为22.1～24.7mm,与下腹壁深层厚度、浅层厚度和BMI、体质量、测量点到脐部的距离呈正相关(P<0.05),与膀胱容量、膀胱的上下径和左右径呈负相关(P<0.05),而与性别、身高、年龄、膀胱的前后径无相关性(P>0.05)。结论应用超声测量的成人下腹壁厚度为(23.4±6.6)mm,营养状态是最重要的影响因素,这为根据指南针原理设计的排尿报警装置的可行性提供了新的证据,对该装置的进一步研究具有重要的参考意义。
Objective To understand the thickness of the lower abdominal wall in normal adults and to explore the related factors and the significance of the urination warning device designed according to the principle of compass. Methods B-ultrasonography was used to measure the thickness of the lower abdomen and its superficial and deep layers, the anteroposterior diameter, vertical diameter and lateral diameter of the bladder, and measure the height, body mass, distance from the measurement point to the umbilicus, and calculate the body mass of 100 adults. Index (BMI) and bladder capacity to analyze factors that affect the thickness of the lower abdominal wall. Results The thickness of the lower abdominal wall was (23.4±6.6) mm, and the 95% confidence interval was 22.1 to 24.7 mm. The thickness of the lower abdominal wall was positively correlated with the thickness of the lower abdominal wall, the thickness of the superficial layer, BMI, body weight, and the distance from the measurement point to the umbilicus. (P<0.05), negatively correlated with bladder volume, bladder vertical diameter and right and left diameter (P<0.05), but not with sex, height, age, bladder anteroposterior diameter (P>0.05). Conclusions The thickness of the lower abdominal wall in adults measured by ultrasound is (23.4±6.6) mm. Nutritional status is the most important influencing factor. This provides new evidence for the feasibility of a urinary extinguishing device designed according to the principle of compass and further to the device. Research has important reference significance.
