What does it mean to fail a lumbar puncture?

Psychological intervention should be carried out in lumbar puncture.

Preoperative psychological intervention can explain the purpose, process, special position and possible discomfort of lumbar puncture to patients, understand patients' worries and problems through conversation, and then implement patient and meticulous psychological counseling, eliminate patients' fear and tension, gain their trust, so that patients have sufficient psychological preparation.

Intraoperative psychological intervention guided patients to maintain the posture of bowing head, bowing waist and holding knee. Avoid moving during the process of puncture. If you want to cough, notify the doctor first, suspend the operation, avoid damaging the tissue and moving the puncture position. If you have any discomfort, report to the doctor at any time. Observe the patient's complexion, consciousness and vital signs closely and be ready for any rescue.

Postoperative psychological intervention was used to comfort and considerate the patient, praising the patient's cooperation, telling the patient to go to the pillow and lie flat for 4-6 hours, and temporarily fasting, so as to avoid cerebrospinal fluid leakage from the needle eye of the subarachnoid space, resulting in reduced cerebrospinal fluid pressure, headache, dizziness, nausea and vomiting.
