The management of dural puncture in obstetrics and the efficacy of epidural blood patches.

Epidural blood patch is the definitive treatment for post dural puncture headaches (PDH), providing acceptable short-term relief. Disappointingly however debate exists as to their long-term success. To investigate their efficacy in our practice, a retrospective audit of all epidural blood patches performed over a four year period was performed. Patients were subsequently followed up using a postal questionnaire and persistent symptom relief and patient satisfaction was measured. During the study period 87 patients required an epidural blood patch, 11 required repeat patches. 71.26% of patients had complete symptom resolution on discharge. The response rate to follow up survey was 73.26% with the majority, 57.44%, replying that their symptoms returned following their discharge home. Only 25.53% said they would have an epidural or spinal anaesthetic for future deliveries. Epidural blood patches provide excellent short-term relief but long-term results are disappointing. Patients receiving epidural blood patches need improved long-term follow up.

Long-term follow-up of epidural blood patch.

Epidural blood patch (EBP) was performed for the treatment of severe postlumbar puncture cephalalgia in 118 young patients. Following the first EBP, 105 patients had relief of headache. Eleven of the 13 in whom it failed had a second EBP, with adequate relief in 10, giving an overall success of 97.5 percent. Lumbar epidural, caudal, and spinal procedures were successful in 3 patients 105 to 380 days after EBP. Soon after EBP, one patient developed facial paralysis and one complained of episodes of vertigo, dizziness, tinnitus, and ataxia without headaches. Residual complications included backache and/or back stiffness in 22 patients and paresthesia in two. Two-year follow-up revealed 95 percent patient acceptance of the procedure. EBP was found to be a safe, effective method for treating severe postlumbar puncture cephalalgia, provided a proper diagnosis is made and there is no contraindication.

Postspinal headache: use of epidural blood patch.

Epidural blood patch should be considered the treatment of choice for postoperative headache if oral fluids and bed rest provide no relief. There should be no hesitation in performing this procedure, provided there are no contraindications. The two important contraindications are (1) evidence of inflammation or infection on the back when the puncture is to be made and (2) septicemia. A representative case is presented.

Postdural puncture headache: the role of prophylactic epidural blood patch.

Prophylactic epidural blood patch may prevent postdural puncture headache that develops after intentional or inadvertent dural puncture. However, despite earlier reports that this procedure was of value, subsequent studies have failed to show it has significant advantages over delayed blood patch. Reports that were supportive of this technique were based on nonrandomized observational studies with significant selective bias. At the present time, most centers do not routinely offer prophylactic blood patches, and those that do report a variable success rate. A recent case study of permanent neurologic deficit after prophylactic epidural blood patch has also raised some concern about the safety of this prophylactic technique.

Epidural blood patch with allogeneic blood for post-dural puncture headache.

A parturient suffered post dural puncture headache following accidental dural puncture during attempted epidural anesthesia for cesarean section. Post partum fever was regarded as a contraindication to autologous epidural blood patch; compatible and infection-free allogeneic blood was therefore used with good effect and without apparent complications.

Efficacy of a prophylactic epidural blood patch in preventing post dural puncture headache in parturients after inadvertent dural puncture.

BACKGROUND: Postdural puncture headache (PDPH) occurs in up to 80% of parturients who experience inadvertent dural puncture during epidural catheter placement. The authors performed a randomized double blind study to assess the effect of prophylactic epidural blood patch on the incidence of PDPH and the need for therapeutic epidural blood patch. METHODS: Sixty-four parturients who incurred inadvertent dural puncture were randomized to receive a prophylactic epidural blood patch with 20 ml autologous blood (prophylactic epidural blood patch group) or a sham patch (sham group). Subjects were evaluated daily for development of PDPH for a minimum of 5 days after dural puncture. Those who developed a PDPH were followed daily for a minimum of 3 days after resolution of the headache. Subjects with moderate headaches who reported difficulties performing childcare activities and all those with severe headaches were advised to receive a therapeutic epidural blood patch. RESULTS: Eighteen of 32 subjects in each group (56%) developed PDPH. Therapeutic blood patch was recommended in similar numbers of patients in each group. The groups had similar onset time of PDPH, median peak pain scores, and number of days spent unable to perform childcare activities as a result of postural headache. The median duration of PDPH, however, was shorter in the prophylactic epidural blood patch group. CONCLUSIONS: A decrease in the incidence of PDPH or the need for criteria-directed therapeutic epidural patch was not detected when a prophylactic epidural blood patch was administered to parturients after inadvertent dural puncture. However, prophylactic epidural blood patch did shorten the duration of PDPH symptoms.

Epidural anesthesia and analgesia are not impaired after dural puncture with or without epidural blood patch.

UNLABELLED: Previous reports have noted a decrease in the success of subsequent epidural anesthesia and analgesia in patients who have undergone prior dural puncture with or without an epidural blood patch. Our retrospective study evaluated the success of epidural anesthesia and analgesia in all patients at the Mayo Clinic who had received a prior epidural blood patch over a 12-yr period. Each epidural blood patch patient was matched to two patients undergoing epidural anesthesia after previous dural puncture (without epidural blood patch) and to two patients undergoing epidural anesthesia after previous epidural anesthetic (without dural puncture/blood patch). These patients were matched for the duration of time between the initial procedure and subsequent epidural anesthetic and the indication (surgery, labor analgesia, postoperative analgesia) for which the subsequent epidural was performed. Subsequent epidural anesthesia was successful in 28 of 29 (96.6%, exact 95% CI 82.2%-99.9%) patients who had undergone prior blood patch, 55 of 58 (94.8%, 85.6%-98.9%) patients with a history of dural puncture, and 55 of 58 (94.8%, 85.6%-98.9%) patients who had had previous epidural anesthesia. There was no significant difference in the success rate of subsequent epidural anesthesia among groups. We conclude that prior dural puncture, with or without epidural blood patch, does not affect the success rate of subsequent epidural anesthesia. IMPLICATIONS: Patients with postdural puncture headache should not be denied the benefits of an epidural blood patch because of concerns about the impairment of subsequent epidural anesthetics. The success rate of subsequent epidural anesthesia and analgesia in patients who have undergone dural puncture with or without epidural blood patch is similar to that of patients who have undergone two prior epidural anesthetics.

Epidural blood patch for atypical headache following obstetric epidural analgesia.

A case of atypical headache presenting following otherwise unremarkable epidural analgesia in labour is presented. Although there was no suggestion of accidental dural puncture during insertion of the epidural catheter, and despite the unusual features of the headache and complicated case history, an epidural blood patch was performed 13 weeks post-partum, with improvement of the patient's symptoms. A repeat epidural blood patch 2 weeks later completely resolved her headache.

The epidural blood patch. Resolving the controversies.

PURPOSE: To review the literature regarding epidural blood patch (EBP) to generate conclusions relating to the controversial issues surrounding its application. SOURCE: A Medline search was made for relevant publications using keywords epidural blood patch, prophylactic epidural blood patch, dural puncture, and postdural puncture headache. Bibliographies of retrieved articles were hand-searched for relevant articles. Case series and comparative trials were emphasized in the analyses. These were culled and those deemed relevant were reviewed. PRINCIPAL FINDINGS: The majority of the literature consists of observational reports: there are few comparative studies. Headache most likely results from cerebrospinal fluid (CSF) loss leading to intracranial content shift and traction on pain sensitive structures; cerebrovascular alterations may be implicated. An EBP with 10-15 ml blood is indicated and effective therapy for severe headache after dural puncture. There is conflicting evidence regarding larger volume blood injections or delaying EBP for 24 hr or more after the diagnosis of postdural puncture headache (PDPH). Efficacy of EBP is related to a "patch effect" as well as transmission of increased epidural space pressure to the CSF space. Previous estimates of EBP efficacy were overgenerous; persistent symptomatic relief can be expected in 61-75% of patients with initial EBP. Patching with non-blood solutions, although initially effective, is associated with a high incidence of headache recurrence. Prophylactic injection of saline or blood decreases the incidence of severe headache after dural puncture. CONCLUSION: Blood-patching is an effective treatment of PDPH but further research is required regarding its mechanisms and prophylaxis.

Postpartum headache after epidural blood patch: investigation and diagnosis.

Use of an epidural blood patch to treat spinal headache after accidental dural puncture is well recognized. The high success rate associated with this practice has been questioned and it is not uncommon for patients to suffer recurring headaches after a supposedly successful blood patch. We describe a patient in labour who suffered accidental dural puncture, and whose headache was treated twice with an epidural blood patch. Despite this, the headache persisted. The case highlights the difficulty in the diagnosis of headache in the postnatal period in patients who have had regional analgesia and the importance of considering an alternative pathology, even if epidural blood patching has been successful. In this case, a diagnosis of cortical vein thrombosis was made. The incidence, presentation, aetiology and treatment of this rare condition is described.

Epidural blood patch placed in the presence of an unknown cervical epidural hematoma.

We discuss a case detailing a favorable outcome of an epidural blood patch performed in the presence of an unknown cervical epidural hematoma. The case highlights the use of a spinal needle for epidural space confirmation, the importance of waiting for final consultation and radiologic testing results before therapeutic intervention when possible, and the use of an epidural blood patch, even in the setting of a known epidural hematoma.

Exacerbation of post-dural puncture headache after epidural blood patch.

The purpose of this report is to describe a new complication of epidural blood patch for inadvertent dural puncture. A dural tap in an obstetric patient was managed initially with a prophylactic blood patch via the epidural catheter. Despite this, 48 hr later, she developed post-dural puncture headache, neck, and shoulder pain, and was given a second epidural blood patch. This was followed by an immediate and severe exacerbation of her symptoms, which later resolved after the administration of diclofenac. There were no further sequelae. Although severe complications of epidural blood patch are rare, they are alarming. Exacerbation of the original symptoms of post-dural puncture headache caused by, or following, epidural blood patching has not previously been reported.

Correlation of adverse neurological outcomes with increasing volumes and delayed administration of autologous epidural blood patches for postdural puncture headaches.

INTRODUCTION: Epidural blood patches (EBPs) usually afford rapid and successful treatment outcomes for postdural puncture headaches (PDPH) with few adverse sequelae. PATIENTS AND METHODS: In order to identify potential risk factors for any adverse outcomes of EBP, a Medline search, 1966 to the present, of case reports and series of any adverse outcomes following EBP for PDPH was conducted. The literature search identified 26 patient cases with 21 cases defined as adverse neurological outcomes, and further stratified as compression or noncompression syndromes, and five cases defined as persistent cranial nerve (CN) palsies. Cases were also stratified by age, sex, and blood volumes of EBP or delays in administration, and compared for statistically significant differences in continuous variables by unpaired, two-tailed t-tests and for significant correlations between predictor variables, including EBP volumes and delays in administration, and adverse neurological outcomes, by simple linear regression analysis. RESULTS: There were no statistically significant sex differences in the mean ages or weights of the study population, or in the total volumes of autologous blood injected in EBPs. When the study population was compared for adverse neurological outcomes by compression or noncompression syndromes, patients experiencing compression syndromes received significantly more EBP volumes (35.36 mL) than patients experiencing noncompression (17.46 mL) syndromes (P = 0.025). Regression analysis confirmed a significant direct linear relationship between increasing EBP volumes and worsening adverse neurological outcomes (P = 0.008). In patients with CN palsies associated with PDPH and unrelieved by EBP, regression analysis again confirmed significant direct linear relationships between increasing days waited to perform EBP and increasing duration of CN palsies in months (P = 0.001). CONCLUSIONS: Epidural blood patches for the management of PDPH, especially PDPH associated with CN palsies, should be administered as soon as the diagnosis of PDPH is made with lower volumes of autologous blood (< or =20 mL) to assure the best treatment outcomes.

Pneumocephalus following an epidural blood patch.

Pneumocephalus is a rare complication of epidural block. We report a case of pneumocephalus complicating an epidural blood patch performed 3 days after unintentional dural puncture. Pneumocephalus may occur during an epidural blood patch procedure, even if the epidural needle tip is within the epidural space.

Intracranial hypotension caused by cervical cerebrospinal fluid leak: treatment with epidural blood patch.

UNLABELLED: This report describes treatment with cervical epidural blood patch of low cerebrospinal fluid (CSF) pressure headache resulting from spontaneous CSF leak via a tear in a cervical dural cuff. The leak was diagnosed by a dynamic computed tomography (CT)-myelography study followed by gadolinium enhanced magnetic resonance imaging(MRI)-scan. The epidural needle was inserted with the aid of image intensifier and CT-scan to guide the needle to the precise site of the CSF leak. Blood mixed with gadolinium was injected, and subsequent MRI scanning provided the first description of spread of blood after cervical epidural blood patch. IMPLICATIONS: Low cerebrospinal fluid (CSF) pressure may cause severe posturally-related headache. In the patient, a vertebral disc protrusion in the neck seems to have contributed to a CSF leak. An injection of blood into the epidural space at the precise site of the CSF leak was followed by complete and lasting resolution of the headache.

Lidocaine inhibits blood coagulation: implications for epidural blood patch.

Lidocaine in the epidural space, through inhibitory effects upon coagulation, may contribute to inefficacy of epidural autologous blood patch (EBP). This study was undertaken to evaluate the effect of achievable epidural concentrations of lidocaine on blood coagulation as a step in testing this hypothesis. Ex vivo blood coagulation using whole blood (n = 20) was studied with computerized thrombelastography (TEG). Each blood specimen was exposed to serial dilutions of lidocaine hydrochloride or saline to form end-concentrations of 0.0 mM, 2.3 mM, 4.6 mM, 9.2 mM, 18.5 mM, and 36.9 mM lidocaine. Statistical analysis using analysis of variance for repeated measures revealed that the three highest lidocaine concentrations tested caused hypocoagulable and/or fibrinolytic changes as compared with controls. Achievable epidural admixtures of lidocaine and whole blood will impair coagulation. Therefore, residual lidocaine in the epidural space may contribute to failures of immediate or early EBP.

Epidural blood patch for post dural puncture headache: a handy ally [corrected].

BACKGROUND: Epidural blood patch is a well-known item in the management protocol of post dural puncture headache though never been practised or reported in our environment. The aim of this report is to document its efficacy and establish a rationale for its use. METHOD: A review of the case record of patients with post dural puncture headache and the relevant literature. RESULT: A case of post dural puncture headache was encountered at a free medical missionary outreach program following spinal anaesthesia for myomectomy. Having exhausted all the available conservative management options, she was offered epidural blood patch. The recovery profile was collected by assessment of her abilities and disabilities before and after the epidural blood patch, with visual analog scale for pain. The clinical condition improved a lot, with remarkable improvement in neck movement and the visual analog scale. CONCLUSION: We conclude that epidural blood patch is a superior therapy for post dural puncture headache and recommend that post-anaesthetic rounds be conducted routinely to identify complications and enable early institution of therapy.

Regional analgesia following epidural blood patch.

During the period November 1972 through October 1974, 118 epidural blood patch procedures were performed for severe postlumbar-puncture cephalgia. Subsequently, in a period varying from 105 to 380 days, three patients, two of whom had twice undergone epidural blood patch, were readmitted for either surgical operation or delivery. Either epidural, caudal, or spinal block was successfully accomplished. During the epidural block, the epidural block the epidural space was easily identified and no resistance was felt either to injection of the local anesthetic or to advancement of the epidural catheter. During the spinal block, ligmentum flavum was distinctly felt from the dura. The extent of the blocks, the onset and duration of action ofpivacaine, mepivacaine, and lidocaine were within normal limits. It is, therefore, concluded that epidural blood patch does not obliterate the epidural space and should not preclude the use of regional block for later surgical or obstetric procedures.
