Introduction
Before using the indwelling catheter on the second day, first examine the condition of the catheter, disinfect the connection site, then attach the infusion tubing to the end of the indwelling catheter. Observe whether the fluid flows properly. If not, consider the possibility of catheter occlusion. For mild blockage, flush with normal saline; for severe blockage, consider replacing the indwelling catheter.
Generally speaking, when using an indwelling needle on the second day, simply disinfect it and then connect it to the infusion tubing. Specific procedures are as follows:
Before using the indwelling needle on the second day, first check its condition—ensure the position hasn't shifted and the catheter isn't bent. If no abnormalities are found, disinfect the connection site, then attach the infusion tubing to the end of the indwelling needle. Observe whether the fluid flows smoothly. If not, consider the possibility of needle blockage. For mild blockages, flush with normal saline; however, if the blockage is severe, replacement of the indwelling needle should be considered.
Compared to conventional intravenous needles, indwelling needles are simpler to use and reduce the pain associated with repeated venipunctures. However, their use must always be performed under the guidance of a qualified healthcare professional to avoid increased pain or severe bleeding.
