Intravenous catheters are a type of device that is very common in medicine. Taking into account the rigor of medicine itself, the use of various equipment that is compatible with it also requires rigor, and the same is true for puncture behavior. Based on the strict requirements of professional venous catheter puncture activities, this article introduces the issues that need to be paid attention to during the puncture process:
Before performing venous catheter puncture activities, in addition to cleaning themselves and wearing corresponding protective measures, doctors also need to fill various pipes with heparin saline to achieve disinfection of the pipes. During disinfection, the safety IV catheters must be filled with heparin saline and then clamped, especially for double-lumen catheters, to prevent the occurrence of air embolism caused by gas entering the blood vessel through the catheter.
The patient's chosen position will have an impact on the success rate of venipuncture. In general, the patient should be asked to lie on the back without the pillow, with small pillows on the shoulders and back, and the puncture side is slightly higher, so that the thorax is in a stretched state (similar to chest expansion). By adopting this position, it will help the patient's clavicle to expand and move upward, thereby allowing the blood vessels to recede. Because the human subclavian vein has a layer of fascia when it meets the clavicle, the clavicle is forward and the blood vessels are backward. When the fascia is pulled down, the subclavian vein moves forward with the clavicle, which provides a good opportunity for puncturing the subclavian vein to improve the success level of puncture.
When the venous catheter is punctured, attention should also be paid to the depth of the catheter. Under normal circumstances, it is suitable for one end of the catheter tip to be located in the upper half of the superior vena cava, which is located above the pericardial reflex line.
Safety IV catheter puncture process is actually a very common and important intervention in medicine, and its requirements for operating medical staff are reflected in many aspects such as technical proficiency, work conscientiousness and rigor. In fact, the elaboration of the common venous catheter puncture attention problems in this article is essentially the requirement for the rigor of medical staff. Only by maintaining a rigorous attitude can the progress of medicine be better promoted.
