Abstract
Spontaneous intracranial hypotension (SIH) is a highly disabling but treatable secondary cause of headache. Recent progress in neuroradiological techniques has catalysed understanding of its pathophysiological basis and clinical diagnosis, and facilitated the development of more effective investigation and treatment methods. A UK-based specialist interest group recently produced the first multidisciplinary consensus guideline for the diagnosis and treatment of SIH. Here, we summarise a practical approach to its clinical and radiological diagnosis, symptomatic and non-targeted interventional treatment, radiological identification of leak site and targeted treatment of the leak once it has been localised.

Abstract
BACKGROUND Pain management after surgery is a challenging medical issue, and clinical research in this area has continued. This study aimed to compare the effect of Aminophylline, ketamine, and paracetamol on the pain intensity after deep vitrectomy and compare it with the control group. METHODS In this clinical trial, 240 patients undergoing deep vitrectomy were included in the study. The protocol of the current study was approved in the Ethics committee of Isfahan University of Medical Sciences (IR.MUI.REC.1396.3.876) and this study was registered in Iranian Registry of Clinical Trials (IRCT20210919052523N1) (https://www.irct.ir/trial/58884). The patients were randomly divided into four equal groups. Twenty minutes before surgery, in the first group, 0.15 mg/kg ketamine, in the second group 1 g acetaminophen, in the third group 3 mg/kg of aminophylline, and in the fourth group, normal saline was infused in the same manner. All drugs were diluted with 100 ccs of normal saline and infused intravenously within 15 minutes. The four groups of hemodynamic variables, pain intensity, and rescue analgesic drugs were compared. RESULTS There was no significant difference between the groups based on hemodynamic variables (P>0.05). The severity of pain up to 2 hours after surgery and the rescue to analgesia in the ketamine and paracetamol groups were significantly lower than that of aminophylline and placebo. CONCLUSION Using ketamine or paracetamol effectively decreases pain intensity after deep vitrectomy surgery without producing significant adverse hemodynamic changes.

Abstract
Objectives Post-dural Puncture Headache (PDPH) is prevalent among individuals undergoing lumbar punctures. The non-invasive effect of some drugs, such as aminophylline on PDPH has been investigated in several clinical studies. As there is no comprehensive systematic review and meta-analysis about the preventive and therapeutic effects of aminophylline on PDPH in the literature, the clinical effectiveness of this drug on the prevention and/or treatment of PDPH will be assessed in this study. Methods PubMed/MEDLINE, Embase, WoS (Clarivate Analytics), the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL Complete, Scopus, and Google Scholar as electronic databases will be precisely searched for clinical studies that assessed the effect of aminophylline on PDPH. Studies between 01-01-1980 and 30-06-2020 will be evaluated in this study, and there will not be any language restrictions. Contradictions between the reviewers within any phase of the study (screening, selecting, quality assessment, and data extraction) will be resolved by consensus; in case of unsolved disagreements, a third reviewer will eventually decide. The combination method will be applied according to the methodological resemblance in the selected articles using the Random Effect Model or the Fixed Effect Model. Also, for the included articles, forest plots will be drawn. For assessing statistical heterogeneity, the I2 statistic and the Q-statistic test will be applied. In addition, funnel plots will be used for assessing non-significant study effects and potential reporting bias. Furthermore, Egger’s and Begg’s tests will be done, and publication bias will be indicated by significant findings (P < 0.05). Conclusions It is expected that the results of this study will be of benefit to researchers and clinicians for managing PDPH, and will be reported in conferences and publications.

The comparison of post-dural puncture headache treatment with acetaminophen-caffeine capsule and intravenous mannitol infusion: A randomized single-blind clinical trial. CURRENT JOURNAL OF NEUROLOGY 2021; 20:95-101. [PMID: 38011456 PMCID: PMC8743175 DOI: 10.18502/cjn.v20i2.6745] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/04/2021] [Indexed: 12/05/2022]
Abstract
Background: Post-dural puncture headache (PDPH) is a common problem after spinal anesthesia. Depending on the severity of PDPH, there are both invasive and non-invasive treatments. Caffeine has been used for the treatment of PDPH since 1949, but the administration of mannitol is a novel management to tackle PDPH. This study was conducted to compare the effectiveness of acetaminophen-caffeine and mannitol in the treatment of PDPH. Methods: We enrolled 80 patients with PDPH in the present clinical trial and observed them during 72 hours after cesarean section. Participants were randomly and equally allocated to two groups for treatment with intravenous (IV) mannitol or oral acetaminophen-caffeine. The effects of treatment were evaluated using the visual analogue scale (VAS) questionnaire at hours of 1, 2, 3, 4, 6, 12, 18, 24, and 48. SPSS software was used. Results: Forty patients in each group completed the study. There was a significant reduction in the pain scores of the both groups after treatment, but the interaction between time and group demonstrated that mannitol administration was superior to acetaminophen-caffeine in pain reduction of the patients undergoing spinal anesthesia (P = 0.028). Patients' satisfaction in the mannitol group was significantly higher than the caffeine group (P = 0.001). Conclusion: This study suggests that IV mannitol infusion affects faster and earlier for the treatment of PDPH than acetaminophen-caffeine capsule. Mannitol could be probably more effective for treatment of PDPH.

Abstract
BACKGROUND Accidental dural puncture (ADP) and subsequent post-dural puncture headache (PDPH) remain common complications of epidural procedures for obstetric anesthesia and analgesia. No clear consensus exists on the best way to prevent PDPH after ADP.
CASE SUMMARY We report our findings in twenty parturients who underwent an incorporated strategy of epidural analgesia followed by epidural hydroxyethyl starch (HES) to prevent PDPH after ADP with a 16-gauge Tuohy needle during epidural procedures. ADP with a 16-gauge Tuohy needle occurred in nine parturients undergoing a cesarean section (CS) and in eleven parturients receiving labor analgesia. An epidural catheter was re-sited at the same or adjacent intervertebral space in all patients. After CS, the epidural catheter was used for postoperative pain relief over a 48-h period. After delivery in eleven cases, epidural infusion was maintained for 24 h. Thereafter, 15 mL of 6% HES 130/0.4 was administered via the epidural catheter immediately prior to catheter removal. None of the parturients developed PDPH or neurologic deficits over a follow-up period of at least two months to up to one year postpartum.
CONCLUSION An incorporated strategy of epidural analgesia followed by epidural hydroxyethyl starch may have great efficacy in preventing PDPH after ADP.

Abstract
BACKGROUND Post-dural puncture headache is a common complication after spinal anesthesia for women who undergo cesarean delivery. Intravenous (IV) dexamethasone has been used to reduce the incidence and severity of PDPH with controversial results. This Systemic review and meta-analysis aimed to assess the effects of IV dexamethasone on PDPH. METHODS This study is reported as per Preferred Reporting Items for Systematic and Meta-analysis. The primary outcome was the incidence and severity of PDPH. The secondary outcome variables were the postoperative total analgesic requirement and incidence of nausea and/or vomiting. Twelve randomized controlled trials with a total of 1548 women were included. RESULTS Intravenous (IV) dexamethasone had no effect on the incidence of PDPH (OR = 0.64; CI, 0.39 to 1.05; I2 = 71%, P = 0.08). Intravenous dexamethasone did not show a significant difference in the incidence of PDPH at 24 h at 48 h, and within one week postoperatively with p-values of less than 0.05. In a random-effect model, a pooled analysis showed that IV dexamethasone had no effect on the severity of PDPH in VAS (MD = 0.78; CI, -2.27 to 0.71; I2 = 98%, P = 0.30). CONCLUSION Intravenous dexamethasone failed to decrease the incidence and severity of PDPH in women who underwent cesarean delivery under spinal anesthesia.

Abstract
Dexamethasone is a synthetic steroid that has been used for many years in the clinical routine due to its anti-inflammatory, anti-allergic and immunosuppressive properties. Furthermore, dexamethasone has been used for a long time for prophylaxis and treatment of chemotherapy-induced nausea and vomiting. In the meantime dexamethasone has been approved as standard for the prophylaxis and treatment of postoperative nausea and vomiting (PONV). This review article outlines the indications and side effects of the perioperative administration of dexamethasone.

Abstract
Background Post-dural puncture headache (PDPH) is one of the most common complications of neuraxial anaesthesia. It limits patients’ general activity and increases the length of hospital stays and the use of care. It is particularly disabling during the postpartum period, when mothers have to take care of their child. Epidural blood patch is the standard treatment for PDPH. However, it is an invasive procedure that may result in rare but serious complications. Recent evidence has suggested that adrenocorticotropic hormone (ACTH) is effective in the management of PDPH. The aim of this study is to assess the efficacy and safety of tetracosactide (Synacthen®), a synthetic analogue of ACTH, for PDPH treatment in patients who receive neuraxial anaesthesia during labour. Methods This randomised, double-blind, placebo-controlled, parallel-arm trial, is performed in two French university hospitals. Eligible patients are those suffering from postpartum PDPH, who are randomised to receive either 1 mg of tetracosactide intravenously over 20 min or to 0.9% saline (placebo). The primary endpoint is the rate of epidural blood patch within a 15-day follow-up period. Headache duration, pain intensity, reduction of general activity, increase in length of hospital stay, adverse events, analgesic use (type and duration) and number of blood patches per patient in each group are recorded. Discussion We expect a decrease in the use of epidural blood patch in those receiving tetracosactide, thus indicating a decrease in PDPH symptoms in these patients. This will define the therapeutic success of tetracosactide and the possibility to use this treatment as a non-invasive alternative to blood patch for PDPH treatment.

Abstract
Background: The actions of caffeine as an antagonist of adenosine receptors have been extensively studied, and there is no doubt that both daily and sporadic dietary consumption of caffeine has substantial biological effects on the nervous system. Caffeine influences headaches, the migraine syndrome in particular, but how is unclear. Materials and Methods: This is a narrative review based on selected articles from an extensive literature search. The aim of this study is to elucidate and discuss how caffeine may affect the migraine syndrome and discuss the potential pathophysiological pathways involved. Results: Whether caffeine has any significant analgesic and/or prophylactic effect in migraine remains elusive. Neither is it clear whether caffeine withdrawal is an important trigger for migraine. However, withdrawal after chronic exposure of caffeine may cause migraine-like headache and a syndrome similar to that experienced in the prodromal phase of migraine. Sensory hypersensitivity however, does not seem to be a part of the caffeine withdrawal syndrome. Whether it is among migraineurs is unknown. From a modern viewpoint, the traditional vascular explanation of the withdrawal headache is too simplistic and partly not conceivable. Peripheral mechanisms can hardly explain prodromal symptoms and non-headache withdrawal symptoms. Several lines of evidence point at the hypothalamus as a locus where pivotal actions take place. Conclusion: In general, chronic consumption of caffeine seems to increase the burden of migraine, but a protective effect as an acute treatment or in severely affected patients cannot be excluded. Future clinical trials should explore the relationship between caffeine withdrawal and migraine, and investigate the effects of long-term elimination.

Abstract
Objective To investigate the effect of the pre-administration with aminophylline on the occurrence of post-dural puncture headache (PDPH) in women undergoing caesarean section by combined spinal-epidural anaesthesia (CSEA). Methods The study enrolled women undergoing elective caesarean sections with CSEA and randomly allocated them into two groups; for 30 min immediately after the infant was delivered, group A received 250 mg aminophylline intravenously and group B received an equal volume of normal saline. Demographic data, operation time, intraoperative blood loss, intraoperative transfusion volume and the occurrence of PDPH during the first 7 days after the operation were recorded. Side-effects such as hypersensitivity, convulsion and arrhythmia were also recorded in the patients and infants in group A within 24 h after aminophylline administration. Results A total of 120 patients aged 24–38 years (pregnancy range, 38–42 weeks) were randomly allocated into two groups (n = 60). The incidence of PDPH in group A was significantly lower than group C (two of 59 [3.4%] versus 10 of 58 [17.2%], respectively). There were no related side-effects within 24 h after aminophylline administration in group A. Conclusions Intraoperative intravenous infusion of 250 mg aminophylline reduced the incidence of PDPH after caesarean section under CSEA with no side-effects.

Abstract
BACKGROUND Intraoperative nausea and vomiting (IONV) or postoperative nausea and vomiting (PONV) affecting women undergoing regional anesthesia for cesarean section is an important clinical problem since these techniques are used widely. There are burdens of literature about IONV/PONV and several in parturient and cesarean. However, it needs more attention. The underlying mechanisms of IONV and PONV in the obstetrical setting mainly include hypotension due to sympathicolysis during neuraxial anesthesia, bradycardia owing to an increased vagal tone, the visceral stimulation via the surgical procedure and intravenously administered opioids. METHODS Given the high and even increasing rate of cesarean sections and the sparse information on the etiology, incidence and severity of nausea and vomiting and the impact of prophylactic measures on the incidence of PONV/IONV, this article aims to review the available information and provide pragmatic suggestions on how to prevent nausea and vomiting in this patient cohort. Current literature and guidelines were identified by electronic database searching (MEDLINE via PubMed and Cochrane database of systematic reviews) up to present, searching through reference lists of included literature and personal contact with experts. DISCUSSION AND CONCLUSION Taking into account the current guidelines and literature as well as everyday clinical experience, the first step for decreasing the incidence of IONV and PONV is a comprehensive management of circulatory parameters. This management includes liberal perioperative fluid administration and the application of vasopressors as the circumstances require. By using low-dose local anesthetics, an additional application of intrathecal or spinal opioids or hyperbaric solutions for a sufficient controllability of neuraxial distribution, maternal hypotension might be reduced. Performing a combined spinal-epidural anesthesia or epidural anesthesia may be considered as an alternative to spinal anesthesia. Antiemetic drugs may be administered restrainedly due to off-label use in pregnant women for IONV or PONV prophylaxis and may be reserved for treatment.

Abstract
BACKGROUND Post-dural puncture headache (PDPH) is one of the most common complications of diagnostic and therapeutic lumbar punctures. PDPH is defined as any headache occurring after a lumbar puncture that worsens within 15 minutes of sitting or standing and is relieved within 15 minutes of the patient lying down. Researchers have suggested many types of interventions to help prevent PDPH. It has been suggested that aspects such as needle tip and gauge can be modified to decrease the incidence of PDPH. OBJECTIVES To assess the effects of needle tip design (traumatic versus atraumatic) and diameter (gauge) on the prevention of PDPH in participants who have undergone dural puncture for diagnostic or therapeutic causes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL and LILACS, as well as trial registries via the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal in September 2016. We adopted the MEDLINE strategy for searching the other databases. The search terms we used were a combination of thesaurus-based and free-text terms for both interventions (lumbar puncture in neurological, anaesthesia or myelography settings) and headache. SELECTION CRITERIA We included randomized controlled trials (RCTs) conducted in any clinical/research setting where dural puncture had been used in participants of all ages and both genders, which compared different tip designs or diameters for prevention of PDPH DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. MAIN RESULTS We included 70 studies in the review; 66 studies with 17,067 participants were included in the quantitative analysis. An additional 18 studies are awaiting classification and 12 are ongoing. Fifteen of the 18 studies awaiting classification mainly correspond to congress summaries published before 2010, in which the available information does not allow the complete evaluation of all their risks of bias and characteristics. Our main outcome was prevention of PDPH, but we also assessed the onset of severe PDPH, headache in general and adverse events. The quality of evidence was moderate for most of the outcomes mainly due to risk of bias issues. For the analysis, we undertook three main comparisons: 1) traumatic needles versus atraumatic needles; 2) larger gauge traumatic needles versus smaller gauge traumatic needles; and 3) larger gauge atraumatic needles versus smaller gauge atraumatic needles. For each main comparison, if data were available, we performed a subgroup analysis evaluating lumbar puncture indication, age and posture.For the first comparison, the use of traumatic needles showed a higher risk of onset of PDPH compared to atraumatic needles (36 studies, 9378 participants, risk ratio (RR) 2.14, 95% confidence interval (CI) 1.72 to 2.67, I2 = 9%).In the second comparison of traumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH, with the exception of one study comparing 26 and 27 gauge needles (one study, 658 participants, RR 6.47, 95% CI 2.55 to 16.43).In the third comparison of atraumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH.We observed no significant difference in the risk of paraesthesia, backache, severe PDPH and any headache between traumatic and atraumatic needles. Sensitivity analyses of PDPH results between traumatic and atraumatic needles omitting high risk of bias studies showed similar results regarding the benefit of atraumatic needles in the prevention of PDPH (three studies, RR 2.78, 95% CI 1.26 to 6.15; I2 = 51%). AUTHORS' CONCLUSIONS There is moderate-quality evidence that atraumatic needles reduce the risk of post-dural puncture headache (PDPH) without increasing adverse events such as paraesthesia or backache. The studies did not report very clearly on aspects related to randomization, such as random sequence generation and allocation concealment, making it difficult to interpret the risk of bias in the included studies. The moderate quality of the evidence for traumatic versus atraumatic needles suggests that further research is likely to have an important impact on our confidence in the estimate of effect.

Abstract
OBJECTIVE This study evaluated the efficacy of IV cosyntropin as an alternative to epidural blood patch (EBP) for refractory or severe post-dural puncture headache (PDPH). METHODS Twenty-eight patients were randomized to receive EBP or intravenous cosyntropin after diagnosis with post-dural puncture headache. Efficacy was evaluated immediately after treatment and at 1 day, 3 days, and 7 days following treatment using self-reported verbal reported scores for pain and function related to their headache on a 10-point scale using two-way repeated measures analysis of variance (ANOVA) with multiple comparisons. RESULTS Baseline information for the control and study cohorts showed no difference based on intent to treat analysis. EBP showed significant improvement over cosyntropin at day 1 (P < 0.001) for VRS pain and function scores; however, cosyntropin demonstrated similar efficacy to EBP immediately after treatment and days 3 and 7 post treatment (respectively, P = 0.459, P = 0.391 and 0.925 for pain and P = 0.189 and 0.478 for function). Treatment effects remained at day 1 after multivariate analysis (P < 0.001 and P = 0.002 for pain and function, respectively). CONCLUSIONS It is reasonable to consider IV cosyntropin as the treatment of choice for patients in whom EBP is contraindicated or in austere environments where there is limited or no access to anesthesia trained providers. Future research should compare efficacy and cost of prophylaxis to treatment of PDPH with intravenous cosyntropin and evaluate the most effective dosing regimen, including duration, number, and strength of doses.

Abstract
BACKGROUND Post-dural puncture headache (PDPH) is a common complication of lumbar punctures. Several theories have identified the leakage of cerebrospinal fluid (CSF) through the hole in the dura as a cause of this side effect. It is therefore necessary to take preventive measures to avoid this complication. Prolonged bed rest has been used to treat PDPH once it has started, but it is unknown whether prolonged bed rest can also be used to prevent it. Similarly, the value of administering fluids additional to those of normal dietary intake to restore the loss of CSF produced by the puncture is unknown. This review is an update of a previously published review in the Cochrane Database of Systematic Reviews (Issue 7, 2013) on "Posture and fluids for preventing post-dural puncture headache". OBJECTIVES To assess whether prolonged bed rest combined with different body and head positions, as well as administration of supplementary fluids after lumbar puncture, prevent the onset of PDPH in people undergoing lumbar puncture for diagnostic or therapeutic purposes. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and LILACS, as well as trial registries up to February 2015. SELECTION CRITERIA We identified randomized controlled trials that compared the effects of bed rest versus immediate mobilization, head-down tilt versus horizontal position, prone versus supine positions during bed rest, and administration of supplementary fluids versus no/less supplementation, as prevention measures for PDPH in people who have undergone lumbar puncture. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the studies for eligibility through the web-based software EROS (Early Review Organizing Software). Two different review authors independently assessed risk of bias using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. We resolved any disagreements by consensus. We extracted data on cases of PDPH, severe PDPH, and any headache after lumbar puncture and performed intention-to-treat analyses and sensitivity analyses by risk of bias. We assessed the evidence using GRADE (Grading of Recommendations Assessment, Development and Evaluation) and created a 'Summary of findings' table. MAIN RESULTS We included 24 trials with 2996 participants in this updated review. The number of participants in each trial varied from 39 to 382. Most of the included studies compared bed rest versus immediate mobilization, and only two assessed the effects of supplementary fluids versus no supplementation. We judged the overall risk of bias of the included studies as low to unclear. The overall quality of evidence was low to moderate, downgraded because of the risk of bias assessment in most cases. The primary outcome in our review was the presence of PDPH.There was low quality evidence for an absence of benefits associated with bed rest compared with immediate mobilization on the incidence of severe PDPH (risk ratio (RR) 0.98; 95% confidence interval (CI) 0.68 to 1.41; participants = 1568; studies = 9) and moderate quality evidence on the incidence of any headache after lumbar puncture (RR 1.16; 95% CI 1.02 to 1.32; participants = 2477; studies = 18). Furthermore, bed rest probably increased PDPH (RR 1.24; 95% CI 1.04 to 1.48; participants = 1519; studies = 12) compared with immediate mobilization. An analysis restricted to the most methodologically rigorous trials (i.e. those with low risk of bias in allocation method, missing data and blinding of outcome assessment) gave similar results. There was low quality evidence for an absence of benefits associated with fluid supplementation on the incidence of severe PDPH (RR 0.67; 95% CI 0.26 to 1.73; participants = 100; studies = 1) and PDPH (RR 1; 95% CI 0.59 to 1.69; participants = 100; studies = 1), and moderate quality evidence on the incidence of any headache after lumbar puncture (RR 0.94; 95% CI 0.66 to 1.34; participants = 200; studies = 2). We did not expect other adverse events and did not assess them in this review. AUTHORS' CONCLUSIONS Since the previous version of this review, we found one new study for inclusion, but the conclusion remains unchanged. We considered the quality of the evidence for most of the outcomes assessed in this review to be low to moderate. As identified studies had shortcomings on aspects related to randomization and blinding of outcome assessment, we therefore downgraded the quality of the evidence. In general, there was no evidence suggesting that routine bed rest after dural puncture is beneficial for the prevention of PDPH onset. The role of fluid supplementation in the prevention of PDPH remains unclear.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in Issue 8, 2011, on 'Drug therapy for treating post-dural puncture headache'.Post-dural puncture headache (PDPH) is the most common complication of lumbar puncture, an invasive procedure frequently performed in the emergency room. Numerous pharmaceutical drugs have been proposed to treat PDPH but there are still some uncertainties about their clinical effectiveness. OBJECTIVES To assess the effectiveness and safety of drugs for treating PDPH in adults and children. SEARCH METHODS The searches included the Cochrane Central Register of Controlled Trials (CENTRAL 2014, Issue 6), MEDLINE and MEDLINE in Process (from 1950 to 29 July 2014), EMBASE (from 1980 to 29 July 2014) and CINAHL (from 1982 to July 2014). There were no language restrictions. SELECTION CRITERIA We considered randomised controlled trials (RCTs) assessing the effectiveness of any pharmacological drug used for treating PDPH. Outcome measures considered for this review were: PDPH persistence of any severity at follow-up (primary outcome), daily activity limited by headache, conservative supplementary therapeutic option offered, epidural blood patch performed, change in pain severity scores, improvements in pain severity scores, number of days participants stay in hospital, any possible adverse events and missing data. DATA COLLECTION AND ANALYSIS Review authors independently selected studies, assessed risk of bias and extracted data. We estimated risk ratios (RR) for dichotomous data and mean differences (MD) for continuous outcomes. We calculated a 95% confidence interval (CI) for each RR and MD. We did not undertake meta-analysis because the included studies assessed different sorts of drugs or different outcomes. We performed an intention-to-treat (ITT) analysis. MAIN RESULTS We included 13 small RCTs (479 participants) in this review (at least 274 participants were women, with 118 parturients after a lumbar puncture for regional anaesthesia). In the original version of this Cochrane review, only seven small RCTs (200 participants) were included. Pharmacological drugs assessed were oral and intravenous caffeine, subcutaneous sumatriptan, oral gabapentin, oral pregabalin, oral theophylline, intravenous hydrocortisone, intravenous cosyntropin and intramuscular adrenocorticotropic hormone (ACTH).Two RCTs reported data for PDPH persistence of any severity at follow-up (primary outcome). Caffeine reduced the number of participants with PDPH at one to two hours when compared to placebo. Treatment with caffeine also decreased the need for a conservative supplementary therapeutic option.Treatment with gabapentin resulted in better visual analogue scale (VAS) scores after one, two, three and four days when compared with placebo and also when compared with ergotamine plus caffeine at two, three and four days. Treatment with hydrocortisone plus conventional treatment showed better VAS scores at six, 24 and 48 hours when compared with conventional treatment alone and also when compared with placebo. Treatment with theophylline showed better VAS scores compared with acetaminophen at two, six and 12 hours and also compared with conservative treatment at eight, 16 and 24 hours. Theophylline also showed a lower mean "sum of pain" when compared with placebo. Sumatriptan and ACTH did not show any relevant effect for this outcome.Theophylline resulted in a higher proportion of participants reporting an improvement in pain scores when compared with conservative treatment.There were no clinically significant drug adverse events.The rest of the outcomes were not reported by the included RCTs or did not show any relevant effect. AUTHORS' CONCLUSIONS None of the new included studies have provided additional information to change the conclusions of the last published version of the original Cochrane review. Caffeine has shown effectiveness for treating PDPH, decreasing the proportion of participants with PDPH persistence and those requiring supplementary interventions, when compared with placebo. Gabapentin, hydrocortisone and theophylline have been shown to decrease pain severity scores. Theophylline has also been shown to increase the proportion of participants that report an improvement in pain scores when compared with conventional treatment.There is a lack of conclusive evidence for the other drugs assessed (sumatriptan, adrenocorticotropic hormone, pregabalin and cosyntropin).These conclusions should be interpreted with caution, due to the lack of information to allow correct appraisal of risk of bias, the small sample sizes of the studies and also their limited generalisability, as nearly half of the participants were postpartum women in their 30s.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in Issue 3, 2012. Caffeine has been added to common analgesics such as paracetamol, ibuprofen, and aspirin, in the belief that it enhances analgesic efficacy. Evidence to support this belief is limited and often based on invalid comparisons. OBJECTIVES To assess the relative efficacy of a single dose of an analgesic plus caffeine against the same dose of the analgesic alone, without restriction on the analgesic used or the pain condition studied. We also assessed serious adverse events. SEARCH METHODS We searched CENTRAL, MEDLINE, and EMBASE from inception to 28 August 2014, the Oxford Pain Relief Database, and also carried out Internet searches and contacted pharmaceutical companies known to have carried out trials that have not been published. SELECTION CRITERIA We included randomised, double-blind studies that compared a single dose of analgesic plus caffeine with the same dose of the analgesic alone in the treatment of acute pain. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the eligibility and quality of studies, and extracted data. Any disagreements or uncertainties were settled by discussion with a third review author. We sought any validated measure of analgesic efficacy, but particularly the number of participants experiencing at least 50% of the maximum possible pain relief over four to six hours, participants reporting a global evaluation of treatment of very good or excellent, or headache relief after two hours. We pooled comparable data to look for a statistically significant difference, and calculated numbers needed to treat to benefit (NNT) with caffeine. We also looked for any numerical superiority associated with the addition of caffeine, and information about any serious adverse events. MAIN RESULTS We identified no new studies with available results for this update. The earlier review included 20 studies (7238 participants) in valid comparisons, but because we used different outcomes for some headache studies, the number of participants in the analyses of the effects of caffeine is now 4262 when previously it was 5243. The studies were generally of good methodological quality, using standard designs and mostly standard scales of pain measurement, although many of those treating postoperative pain were small.Most studies used paracetamol or ibuprofen, with 100 mg to 130 mg caffeine, and the most common pain conditions studied were postoperative dental pain, postpartum pain, and headache. There was a small but statistically significant benefit with caffeine used at doses of 100 mg or more, which was not dependent on the pain condition or type of analgesic. About 5% to 10% more participants achieve a good level of pain relief (at least 50% of the maximum over four to six hours) with the addition of caffeine, giving a NNT of about 14 (high quality evidence).Most comparisons individually demonstrated numerical superiority with caffeine, but not statistical superiority. One serious adverse event was reported with caffeine, but was considered unrelated to any study medication.We know of the existence of around 25 additional studies with almost 12,500 participants for which data for analysis were not obtainable. The additional analgesic effect of caffeine remained statistically significant but clinically less important even if all the known missing data had no effect; the bulk of the unobtainable data are reported to have similar results as this review. AUTHORS' CONCLUSIONS The addition of caffeine (≥ 100 mg) to a standard dose of commonly used analgesics provides a small but important increase in the proportion of participants who experience a good level of pain relief.

Abstract
Background Post dural puncture headache (PDPH) is an iatrogenic cause of patient morbidity in pain management after spinal or epidural anaesthesia, as well as after diagnostic lumbar puncture. Most patients respond to conservative treatment or to epidural blood patch, yet limited options for effective treatment are available for patients who fail these treatments or present with theoretical contraindication. Case report We present a case of a patient with previously diagnosed human immunodeficiency virus and hepatitis C, who presented with signs of PDPH, which placed him at a theoretical risk of meningeal seeding of the virus during the blood patching procedure. Conclusion We successfully treated the post dural puncture headache and avoided the risk of viral seeding of the meninges by using a fibrin sealant.
