The Current Use of Lumbar Puncture in a General Paediatric Unit

Aim This study evaluated the use of Lumbar Puncture (LP) in a general paediatric unit over a 3-year period. Methods Index patients, who had a successful LP, were identified from the microbiology database and failed LP procedures were identified from a chart review of the serum PCR database. Data abstracted included 1) patient age, 2) LP indication, 3) LP procedure outcome; classified as atraumatic, traumatic or failed, 4) grade of doctor undertaking the procedure and 5) the final diagnosis. Results We identified 104 paediatric patients, of whom 29(27.9%) were neonates. LP was indicated for the evaluation of acute undifferentiated illnesses, with 33 (31.7%) patients having fever without source beyond the neonatal period and 16 (15.4%) being neonates with fever. A CSF sample was obtained in 96 (92.4%) patients, with 71 (73.9%) being atraumatic. Successful LP was undertaken by Consultants in 4 (4.1%), Registrars in 83 (86.5%) and SHOs in 9 (9.4%) patients. 14 (14.6%) patients had positive CSF cultures with an additional 23 having positive cultures or serology (9 blood cultures, 11 urine cultures and 3 positive serum PCR). Conclusion Skill in LP performance is still required, to evaluate acute undifferentiated illness, in general paediatric units and ancillary methods to aid SHOs with LP skill development is desirable.
