Proper Technique for Performing a Lumbar Puncture

Patient Preparation and Positioning

A lumbar puncture (LP), commonly referred to as a spinal tap, is a critical procedure used in microbiology and neurology for diagnostic purposes, including cerebrospinal fluid (CSF) analysis.

Patient Preparation

• Obtain informed consent and explain the procedure.
• Assess for contraindications such as increased intracranial pressure or coagulopathy.
• Ensure sterile technique and gather necessary equipment.

Patient Positioning

Proper positioning is essential for successful LP:

• Lateral decubitus position: The patient should be lying on their side with knees drawn to the chest to widen the intervertebral spaces.
• Sitting position: Alternative for obese patients or those with respiratory complications.
• Ensure relaxation to minimize movement and facilitate needle insertion.

Conclusion

Proper patient preparation and positioning improve procedural success and minimize complications.
