Intravenous catheter in the operating room of the Application Experience


Position, size, capsule, internal echo, the rear effects, and to observe whether the enlarged cervical lymph nodes, tumor with or without high-speed peripheral and low resistance arterial flow within the proposed Ultrasound diagnosis of benign and malignant. 2 results of 58 cases 69 cases of benign tumors,[link widoczny dla zalogowanych], malignant in 11 cases, ultrasound diagnosis and pathologic findings consistent with 67 cases, in line with rate 97.1%, 58 cases were benign (58 cases of encapsulated; the shadow side of 9 cases, no side Shadow 49 cases; effects to enhance or change the rear of 56 cases, reducing the 2; lymph nodes in 2 cases, 56 cases without lymph node enlargement; no blood flow 58 cases), malignant in 11 cases (encapsulated in 2 cases, incomplete 9; without side impact in 11 cases; behind the enhanced effect of change in 3 cases, to reduce the 8; lymph nodes in 8 cases, no enlargement in 3 cases; a high-speed low-low resistance arterial flow in 10 cases, no blood flow 1). 3 discussion can be seen with the capsule of benign and malignant tumors is complete, if there is high-speed peripheral and internal resistivity of the arterial blood flow, enlargement of neck lymph node closer relationship with the rear effects,[link widoczny dla zalogowanych], sound film has a certain relationship between the side , and no significant contact with the tumor size. In addition, the team found that internal calcification in 8 cases, 6 cases were benign, are scattered punctate calcifications, asking a long history of disease is caused by calcification of adenoma; malignant in 2 cases, both papillary calcification. It is worth mentioning that one case showed malignant sonographic morphology rules, encapsulated, homogeneous internal echo, back the same effect, only occurs in the surrounding high-speed low resistance arterial flow. Made based on the above analysis of benign and malignant thyroid tumors ultrasound identification of the six ideas. Benign ultrasound criteria: (1) encapsulated; (2) with or without acoustic shadow side; (3) the effect of the same or increase the rear; (4) internal echo uniform or scattered punctate calcifications; (5) None cervical lymph nodes; (6) No internal high-speed peripheral and low resistance arterial flow. Malignant tumors ultrasound criteria: (1) capsule is not complete; (2) No side of the acoustic shadow; (3) the effect of the same or lower back; (4) internal echo was heterogeneous or papillary calcification; (5) cervical Department of lymph nodes; (6) peripheral and internal exploration and high-speed low resistance of the arterial blood flow. Through careful observation, comprehensive judgments is not difficult to suggest benign or malignant tumors, including (1) (6) the maximum value,[link widoczny dla zalogowanych], as long as the capsule is incomplete or found to occur within the high-speed peripheral and low resistance arterial flow in the one,[link widoczny dla zalogowanych], that should be considered malignant. (Editor: Lee Ji Long) 25 ~ / m1) from the end of the slow bolus needle stitch, and then sterile venous cap closed after the same dose every 6h with heparin saline solution Chong-pin once, and finally with sterile gauze and special catheter attached gum to fully fixed in the limbs. Intravenous infusion once again, just outside the sterile intravenous cap, the one-time infusion with intravenous catheter connection. This will reduce the postoperative treatment to patients suffering. 3.2 The use of intravenous catheter Notes 3.2.1 Select the appropriate vein needle,[link widoczny dla zalogowanych], puncture site and blood vessels. Puncture action to light, steady, accurate and to prevent the repeated puncture of the blood vessels and surrounding tissue damage and increase pain. Master the puncture technique is to obtain success and avoid puncture complications. 3.2.2 Prevention of embolism. One-time infusion before puncture to drain the air stand, followed by infusion needle when success must closely connected to joints to prevent leakage of air embolism formation. Each re-infusion of intravenous catheter or administration, the have to check to ensure that no clotting within the venous catheter and then connected the liquid plug to prevent blood clots from occurring. 3.2.3 intravenous catheter should be fixed firmly to prevent the tube during the patient position change and fall off. 3.2.4 During the catheter insertion site should always observe the situation, watch for fluid leakage and local inflammation, such as that should be removed immediately, and act accordingly, re-establishment of intravenous fluid way. Since the operation of intravenous catheter fast, easy, safe and free heparin cap when not in a sealed tube, in order to maintain intravenous access for several days, and vascular damage, for surgical patients, has been greatly superior to the traditional thick needle infusion. The application of intravenous catheter not only reduces the workload of nurses, but also greatly reduce the suffering of patients and their economic burden.
