| Objective:Adopt electrical bioimpedance gastric motility measurement to study the complicated conditions of functional delayed gastric emptying (FDGE) on neurological critically ill patients, to discuss the nosogenesis and the high risk factors and also to provide objective evidences for the establishment of nutritional support plan and the precaution measures of functional delayed gastric emptying.Methods:First, select60patients with severe gastric motility according to Inclusive Criteria to form an experimental group and another10healthy people to form a control group. Then extract electrogastrogram and impedance gastric motility through gastric motility testing synchronously. And recorded the concentration of blood calcium, kalemia, natremia, serum creatinine; temperature; numeration of leukocyte, HCT(hematokrit); postprandial blood glucose; Glasgow Coma Score and Acute physiology and chronic health evaluationll respectively. Finally, exam the gastric motility data of both teams and undertake Multivariate linear regression analysis on variables with statistical significance.Results:The0-2cpm percentage of impedance gastric motility of experimental group is27.67±2.61%, while the control group is13.2±1.17%; The2-4cpm percentage of impedance gastric motility of experimental group is44.44±5.24%, the control group is56.26±1.91%; The4-6cpm percentage of impedance gastric motility of experimental group is27.88±2.66%, while the control group is30.53±2.31%; The2-4cpm and the4-6cpm percentage of impedance gastric motility of the experimental group are less than those of the control group (P value less than0.001and0.007separately); The impedance gastric motility0-2cpm percentages of the experimental group is obviously increased compared with those of the control group (P value less than0.001). The above differences have statistical significance. The P value of power variable coeffcient of both groups is0.006, which means there are significant differences between them. However,P of the frequency variable coeffcient value0.097which is bigger than0.05, which means there is no obvious statistical difference. After bringing the variables with statistical significance into Multiple linear regression analysis, it is found that the temperature, plasma calcium concentration, postprandial blood glucose and the gastric motility conditions of patients are negative correlations (the regression coefficient is-4.542,-8.44,-1.9separately, and P value0.001,0.011and0.002respectively).Conclusion:It is evident that patients with severe gastric motility have FDGE, and the occur of FDGE is related to the negative correlations of temperature, the concentration of blood calcium and postprandial blood glucose. The higher the patient’s temperature, blood calcium concentration and postprandial blood glucose are, the lower the2-4cpm gastric impedance percentage is. The worse the gastric motility is,the more severe the FDGE is. |
