Diagnostic lumbar puncture. Comparative study between 22-gauge pencil point and sharp bevel needle.

Post-lumbar puncture headache is a frequent clinical problem. Needle design is expected to reduce post-puncture headache. In this study, we compared two different lumbar puncture needle designs in diagnostic lumbar puncture and analysed post-dural puncture headache (PDPH) and social and economical harm associated with the diagnostic lumbar puncture procedure. This prospective, controlled study consisted of 80 consecutive adult patients requiring elective diagnostic lumbar puncture due to various neurological symptoms. Lumbar puncture was completed either with Spinocan 22 G sharp bevel needle or Whitacre 22G pencil point needle. Patients were asked about previous headache symptoms and pain provoked by puncture. One week after the lumbar puncture all patients were interviewed by telephone and occurrence and type of headache, headache intensity, medication and frequency of impairment in activities of daily living were asked. Need for epidural blood patch was also recorded. Thirty-three of 78 (42%) patients experienced headache after diagnostic lumbar puncture and in 26 (33%) the headache could be classified as PDPH. There were no statistically significant differences between needle types in the frequency of common headache, PDPH, puncture pain intensity, need for epidural blood patch or sick leave. Also, there were no other complications except local back pain or headache. In this study, the needle design did not affect the frequency of PDPH. Also, PDPH was common, occurring in 33% cases and caused a considerable amount of disturbance in daily activities. Seeking help for this condition was insufficient and only part of these PDPH patients were treated with epidural blood patch.

Microcatheterization of the cervical epidural space via lumbar puncture: technical note.

OBJECTIVE: Deposition of opiates, corticosteroids, or local anesthetics into the epidural space is useful for the management of painful maladies of the cervical and thoracic spine. We describe a novel technique for epidural medication delivery via an angiographic microcatheter inserted at or below the conus and advanced cephalad under fluoroscopic guidance. Unlike commercial kits used by anesthesiologists, this method uses a radiopaque catheter that can be precisely targeted to the levels of interest. The hazards of direct puncture, such as "wet tap" or injury to the cervical cord, are minimized. METHODS: An 18-gauge Tuohy needle is inserted into the lumbar epidural space. A 2.3-French microcatheter and a 0.018-inch steerable guidewire are then introduced through the lumen of the needle. The catheter is fluoroscopically advanced to the cervical epidural space, where Depo-Medrol (Pharmacia & Upjohn, Kalamazoo, MI) is administered. As the catheter is withdrawn, additional corticosteroid can be delivered to the thoracic epidural space, together with long-acting morphine compounds or local anesthetics. Regional pressures within the epidural space and other physiological parameters can be measured, and the local microenvironment can be sampled. RESULTS: To date, we have performed 16 procedures for 13 patients. All patients reported improvement, of varying extent and duration. There have been no complications. CONCLUSION: Our system of accessing the epidural space has many advantages, compared with direct puncture and commercially available kits. It provides a safe means of delivering epidural medication to multiple spinal levels and permits measurement of physiological variables that may be useful in the diagnosis and treatment of cervical and thoracic spine disease.

Postdural puncture headache in pediatric oncology patients.

This prospective cohort study determined the incidence and risk factors for development of postdural puncture headache (PDPH) in children after lumbar puncture (LP). Eighty-six children were enrolled. LPs were performed with use of 22-gauge spinal needles with the bevel oriented parallel to the long axis of the spine. Follow-up telephone interviews and patients' diary of symptoms were collected. Headache brought on by sitting up and relieved by lying down was defined as PDPH. Of the 80 who completed the study, six (8%) developed PDPH. Two (3%) were less than 6 years old and four (5%) were 6 to 12 years of age. Children with a history of headache following a previous LP were nine times as likely to experience PDPH. PDPH occurs not infrequently in children. A prior history of headache is a predisposing factor.

Anatomical basis of intervertebral disc puncture with chemonucleolysis.

Transparietal puncture of the lumbar intervertebral discs is done to achieve enzymatic nucleolysis. This technique requires firm understanding of the morphology and topography of the anatomical structures traversed by the needle as well as those to be avoided. Vertebral disc puncture with chemonucleolysis has been done by the author for four years. The aim of this study was to identify the parameters allowing facilitation of this procedure, thereby leading to a decreased X-ray exposure. To achieve this goal an analytical study of the target structure and its neurovascular, osseous and visceral relations was carried out. The results of this study led to practical conclusions regarding especially the parameters of disc puncture, their preoperative identification and the risks encountered in case of erroneous puncture.
