Frovatriptan for The Prevention of Postdural Puncture Headache

Preventing Post-Lumbar Puncture Headache

Post-lumbar puncture headache is the main adverse event from lumbar puncture and occurs in 3.5% to 33% of patients, causing functional and socio-professional disability. We searched the post-lumbar puncture headache literature and, based on this review and personal expertise, identified and addressed 19 frequently asked questions regarding post-lumbar puncture headache risk factors and prevention. Among the nonmodifiable factors, older age is associated with a lower incidence of post-lumbar puncture headache, while female sex, lower body mass index, and history of headache might be associated with increased risk. The use of atraumatic, noncutting needles is the most effective intervention for post-lumbar puncture headache prevention. These needles are not more difficult to use than cutting needles. Other commonly recommended measures (eg, fluid supplementation, caffeine) appear unhelpful, and some (eg, bed rest) may worsen post-lumbar puncture headache.

Comparison between the Effects of Sumatriptan Versus Naratriptan in the Treatment of Postdural Puncture Headache in Obstetric Patients: A Randomized Controlled Trial

Background

Postdural puncture headache (PDPH) in the obstetric anesthesia practice is one of the most annoying, common, and important problems.

Aim

This comparative study was designed to assess the efficacy of naratriptan in relieving PDPH in parturients who gave birth by cesarean section under intrathecal anesthesia and to compare its efficacy with sumatriptan.

Settings and Design

One hundred and eighty-nine adult parturients who complained of PDPH in the first 3 days postpartum period were enrolled in this study. They were divided into three equal parallel groups of 63 each.

Materials and Methods

Group-1 controlled (C-group) received multivitamin tablets, Group-2 sumatriptan (S-group) received sumatriptan tablets and Group-3 naratriptan (N-group) received naratriptan tablets. The efficacy of naratriptan in relieving PDPH was studied and compared with that of sumatriptan. Incidences of complications of both drugs were also noted.

Statistical Analysis

The collected data were organized, tabulated, and statistically analyzed using SPSS software statistical computer package version 18 (SPSS Inc., USA).

Results

After the first 6 h, there were statistically significant differences between Groups S and N from one side and control group from the other side (P < 0.0001 and 0.001), respectively, and the difference between Group S and Group N was statistically significant (P = 0.004). After 12 h, there were statistically significant differences between Groups S and N from one side and the control group from the other side (P < 0.0001) and the difference between Group S and Group N was statistically significant (P = 0.002). After 72 h, there were statistically significant differences between Groups S and N from one side and control group from the other side (P < 0.001 and 0.009), respectively. The difference was nonsignificant between S and N group (P = 0.717).

Conclusion

The study revealed that anti-migraine drug naratriptan in combination with supportive treatment was effective in relieving PDPH in parturients.

Continuous Spinal Anesthesia for Obstetric Anesthesia and Analgesia

The widespread use of continuous spinal anesthesia (CSA) in obstetrics has been slow because of the high risk for post-dural puncture headache (PDPH) associated with epidural needles and catheters. New advances in equipment and technique have not significantly overcome this disadvantage. However, CSA offers an alternative to epidural anesthesia in morbidly obese women, women with severe cardiac disease, and patients with prior spinal surgery. It should be strongly considered in parturients who receive an accidental dural puncture with a large bore needle, on the basis of recent work suggesting significant reduction in PDPH when intrathecal catheters are used. Small doses of drug can be administered and extension of labor analgesia for emergency cesarean delivery may occur more rapidly compared to continuous epidural techniques.

The status of diagnosis and treatment to intracranial hypotension, including SIH

Intracranial hypotension, especially spontaneous intracranial hypotension (SIH), is a well-recognized entity associated with cerebrospinal fluid (CSF) leaks, and has being recognized better in resent years, while still woefully inadequate. An increasing number of factors including iatrogenic factors are realized to involve in development and progression of intracranial hypotension. The diagnosis remains difficult due to the various clinical manifestations, some of which are nonspecific and easily to be neglected. Multiple imaging tests are optional in CSF leakage identification while clinicians are still confronted with difficulties when making selection resulting from superiorities and disadvantages of different imaging tests. Treatments for intracranial hypotension are multifarious but evidence is anecdotal. Values of autologous epidural blood patching (EBP), the mainstay of first-line interventional treatment currently, is getting more and more regards while there are no systematic review of its efficacy and risks. Hereby, the purpose of this review was to reveal the present strategy of intracranial hypotension diagnosis and treatment by reviewing literatures, coupled with our experience in clinical work.

Post-dural puncture headache: the worst common complication in obstetric anesthesia

Ever since the first spinal anesthetic in the late 19th century, the problem of "spinal headache" or post-dural puncture headache (PDPH) has plagued clinicians, and more importantly, patients. It has long been realized that the headache and other symptoms that often occur after the entry of a needle into the subarachnoid space is somehow related to fluid loss, although the exact pathophysiology of the headache has really never been defined. With the introduction of pencil-point spinal needles for spinal anesthesia in pregnant women over the past 2 decades, the problem of PDPH in obstetrics has been more associated with accidental dural puncture during attempted epidural procedures. Accidental puncture probably occurs in about 1% of procedures, so with over 60% of pregnant women receiving epidural analgesia for labor, there are probably 20,000-50,000 obstetric patients with PDPH in the United States each year. In this article, we will discuss the current state of knowledge in this area, suggesting that the PDPH syndrome is more severe and often more long-lasting, with some potentially life-threatening complications (cerebral hemorrhage) than usually appreciated or admitted. While prevention and treatment options are still limited, with the only clearly effective treatment being the epidural blood patch, recognition of the PDPH syndrome in postpartum women by anesthesiologists and obstetricians, with aggressive follow-up and treatment, may help limit the associated morbidity and mortality.

Evidence-Based Practice Recommendations to Prevent/Manage Post-Lumbar Puncture Headaches in Pediatric Patients Receiving Intrathecal Chemotherapy

Post-lumbar puncture headaches (PLPHs) are a known complication of lumbar puncture procedures. Children undergoing treatment for cancer often undergo multiple lumbar punctures, placing them at increased risk for PLPHs. There are currently no guidelines for the prevention or management of PLPHs in children. A team was therefore assembled to conduct a systematic review of the evidence in relationship to PLPHs in the pediatric population. Clinical questions were developed and used to guide the literature review. Twenty-four articles were deemed appropriate for use and were evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Based on the review of evidence, strong recommendations are made for the use of smaller needle sizes and for the use of pencil point needles during lumbar puncture procedures. Weak recommendations are made for needle orientation and positioning following the procedure as well as for interventions used to treat PLPHs once they occur. There is a need for additional, pediatric-specific studies to further examine the issue of PLPH prevention and treatment.

Meningeal (postdural) puncture headache, unintentional dural puncture, and the epidural blood patch: a national survey of United States practice

BACKGROUND

Meningeal (postdural) puncture headache (MPH) is a familiar iatrogenic complication. The optimal means of prevention, management, and treatment of this disorder are uncertain. The purpose of this study was to determine current practice among United States (USA) anesthesiologists regarding MPH as well as the related issues of unintentional dural puncture (UDP), the epidural blood patch (EBP), and proposed alternatives to the EBP.

METHODS

A survey form was sent as a single mailing to each practicing USA member of the American Society of Regional Anesthesia and Pain Medicine in June 2006.

RESULTS

Data were analyzed from 1024 returned survey forms (29.4% response rate). Major findings were as follows: Written institutional protocols for managing UDP and MPH are uncommon. The preferred method of immediately dealing with an UDP when providing analgesia for labor is to reattempt the epidural at another level (73.4%). When intrathecal catheters are used for labor analgesia, they are most often removed immediately after delivery (56.5%). After UDP in the obstetric setting, aggressive hydration and encouraging bed rest are the most frequently used prophylactic measures against the development of MPH. Frequently used treatment options for MPH include aggressive hydration, the EBP, oral caffeine, oral nonopioid analgesics, and bed rest. With the exception of a uniform blood volume (16-20 mL), procedural details of the EBP vary considerably among practitioners. The use of materials other than blood for epidural patch is uncommon.

CONCLUSIONS

Various measures, many poorly supported by the literature, are used prophylactically after UDP and in the treatment of MPH. Despite being nearly universally used as treatment of MPH, the EBP procedure itself remains largely nonstandardized.

Management of postdural puncture headache in the obstetric patient

PURPOSE OF REVIEW

The treatment of postdural puncture headache remains controversial, largely because it is insufficiently evidence based. With high rates of neuraxial block in the obstetric population likely to continue, postdural puncture headache will remain a primary cause of morbidity and increased duration of hospital stay. This review describes new reports of relevance published in 2006 and until October 2007.

RECENT FINDINGS

New evidence justifies epidural blood patch as the treatment of choice for severe postdural puncture headache, but technical aspects such as optimal timing and volume are less clear. Symptomatic medical management remains diverse, with a multitude of therapies often advocated, despite a lack of scientific support. Reports of misdiagnosis and of complications associated with postdural puncture headache and its treatment emphasize the importance of multidisciplinary management and additional investigation, including radiological imaging, when the clinical picture warrants.

SUMMARY

The key reports in this epoch have shed light on the benefits of careful assessment of postpartum headache and treatment with an epidural blood patch. New management paradigms have been suggested and serious complications continue to be reported.
