The SCV catheter being misplaced into the internal jugular （IJV） vein is a common occurrence. The present study explores the influence of a misplaced SCV catheter on TPTD variables. Methods： Thirteen severe acute pancreatitis （SAP） patients with malposition of the SCV catheter were enrolled in this study. TPTD variables including cardiac index （CI）, global end-diastolic volume index （GEDVI）, intrathoracic blood volume index （ITBVI）, and extravascular lung water index （EVLWl） were obtained after injection of cold saline via the misplaced SCV catheter. Then, the misplaced SCV catheter was removed and IJV access was constructed for a further set of TPTD variables. Comparisons were made between the TPTD results measured through the IJV and mis- placed SCV accesses. Results： A total of 104 measurements were made from TPTD curves after injection of cold saline via the IJV and misplaced SCV accesses. Bland-Altman analysis demonstrated an overestimation of ＋111.40 ml/m2 （limits of agreement： 6.13 and 216.70 ml/m2） for GEDVI and ITBVI after a misplaced SCV injection. There were no significant influences on CI and EVLWI. The biases of ＋0.17 L/（min.m2） for CI and ＋0.17 ml/kg for EVLWI were re- vealed by Bland-Altman analysis. Conclusions： The malposition of an SCV catheter does influence the accuracy of TPTD variables, especially GEDVI and ITBVI. The position of the SCV catheter should be confirmed by chest X-ray in order to make good use of the TPTD measurements.展开更多

In this study a needle with 6 degrees of freedom force/torque sensor is used to find the relationship between the pathway＇s length and the force. Our experiments show that the method with repeated extraction-insertion cy- cles can make the needle approach the target as much as possible. Meanwhile a method to obtain the appropriaterepeated extraction-insertion cycles is given to drive the needle to execute the repeat- ed cycles efficiently. Experiments and discussions were conducted to preliminarily validate the meth- od.展开更多

Although considered safe and it being a common procedure nasogastric tube misplacement can lead to serious and life-threatening complications. We present three cases of nasogastric tube misplacement in tracheostomized patients. One of the cases presented suffered from pneumothorax. Different time intervals between procedures in these different cases resulted in similar results. We would like to emphasize the importance of due conformation of correct placement of the nasogastric tube in the tracheostomy patient as well as to suggest that over inflation of the balloon securing the tracheostomy apparatus in place during nasogastric tube placement, might prevent misplacement. Nasogastric tube placement in tracheostomized patients has potential for serious complications. As such maintaining safe practice procedure is essential. Considering over inflation of the tracheostomy apparatus balloon might be beneficial as well, by preventing entry of NGT into the trachea.展开更多

Clarifying the supportive function of the family subject, analyzing the causes of the absence, dislocation and dislocation of the family subject, forming the countermeasures of strengthening the propaganda of psychological knowledge, improving the family's understanding of psychological crisis, strengthening the communication between family and school, enhancing the family's trust in school work and the transparency of psychological crisis information, strengthening the construction of parent-child relationship, and improving the tense relationship between some families, especially single-parent families' parents and their children, are the important guarantees and strong supports to assist the prevention and intervention of college students' psychological crisis.展开更多
