Nursing care and precautions after one-time lumbar puncture

Adjust the dripping rate according to different needs, preferably no more than 20 drips per minute. Too fast and excessive drainage may cause the risk of intracranial hematoma or brain herniation. The amount of cerebrospinal fluid drainage should be controlled according to the needs. The total amount of intraoperative drainage is 40 mL to 60 mL, and the daily drainage amount for preventive and therapeutic treatment is about 150 mL and 350 mL, respectively. For those who need blood cerebrospinal fluid replacement, normal saline can be injected through the three-way tube. The volume of normal saline should be less than the amount of cerebrospinal fluid released each time. Intrathecal antibiotics can also be injected through the three-way tube to treat intraventricular infection. Avoid twisting and breaking the catheter to prevent the drainage tube from being blocked. Because the catheter is thin and easy to be blocked by the broken tissue in the cerebrospinal fluid, it can be flushed with a small amount of normal saline. Pay attention to aseptic operation. Redness at the puncture needle eye can be disinfected with iodophor or ethanol cotton balls, and then replaced with sterile dry cotton balls. And daily monitoring of cerebrospinal fluid routine. Pay attention to the patient's position, and you can change the position between 15° and 30° of head height to avoid pressure ulcers.
