Theophylline, Versus Sumatriptan and Gabapentin in The Treatment of Post-Dural Puncture Headache

The aim of this study is to compare the safety and efficacy of theophylline, sumatriptan, and gabapentin in the treatment of post-dural puncture headache.

Neostigmine and Glycopyrrolate for the Treatment of Headache After Dural Puncture

The purpose of this study is to evaluate Neostigmine and Glycopyrrolate to treat post-dural puncture headache (PDPH) to reduce the proportion of postpartum women with a PDPH requiring epidural blood patch (EBP) who developed a PDPH after accidental dural puncture.

Comparison of Post-Dural Puncture Headache After Spinal Anesthesia Using Median Versus Paramedian Approach

This randomized controlled trial will compare two commonly used techniques for performing spinal anesthesia, the median (midline) approach and the paramedian (lateral) approach, in adult patients undergoing elective orthopedic or urology surgery at Mayo Hospital, Lahore. Spinal anesthesia is widely used because it provides rapid pain control during surgery and avoids airway instrumentation. However, a recognized complication is post-dural puncture headache (PDPH), a headache that typically worsens on sitting or standing and improves on lying down. PDPH can delay mobilization, reduce oral intake, prolong hospital stay, and sometimes require additional treatment. Eligible participants aged 18 to 65 years with American Society of Anesthesiologists (ASA) physical status I or II will be enrolled, and then allocated in a 1:1 ratio to receive spinal anesthesia using either the median or paramedian approach. To standardize the procedure, spinal anesthesia will be performed under aseptic technique at the L3 to L4 or L4 to L5 interspace using a 25-gauge Quincke spinal needle, followed by injection of a fixed dose of hyperbaric bupivacaine. Routine perioperative monitoring will be applied for all participants, and intra-operative blood pressure will be recorded at regular intervals to document hypotension. The primary outcomes are the frequency and severity of PDPH. PDPH will be assessed using a structured checklist based on the International Classification of Headache Disorders, 3rd edition (ICHD-3) at 24 hours, 72 hours, and day 5 after the procedure by a trained assessor. Headache intensity will be recorded using a 0 to 10 Visual Analogue Scale, and categorized as mild, moderate, or severe. The hypothesis is that the frequency and severity of PDPH differ between the median and paramedian approaches in patients receiving spinal anesthesia for orthopedic or urology surgery.

Effect of Altitude on Postdural Puncture Headache After Caesarean Delivery

The aim of this study is to examine the effects of altitude (high altitude versus low altitude) on incidence and severity of postural puncture headache (PDPH) following spinal anaesthesia for caesarean delivery. The investigators hypothesized that the risk of PDPH would be higher in highlander parturients than in lowlander parturients.

Factors Associated With the Onset of Chronic Headaches in Patients Who Received a Blood Patch in Post Partum

The purpose of this study is to identify possible links between conditions for carrying out a blood patch (BP) to treat accidental post dural puncture acute headache (PDPH) in the early post partum period and occurrence of chronic headaches at 1 and 6 months.

Evaluation of Post-dural Puncture Headache in Female Patients Undergoing Obstetric and Non-obstetric Surgery

The goal of this observational study is to compare the incidence, severity, and potential risk factors for Post-dural Puncture headaches (PDPH) in obstetric and non-obstetric female patients undergoing spinal anesthesia. The main questions it aims to answer are: Are there differences between these two groups? Are there contributing factors? Researchers will compare obstetric and non-obstetric patients to see if pregnancy affects female patients in context of PDPH. Participants will be monitored periodically for PDPH development. The frequency and severity of headaches will be assessed using the Numerical Rating Scale (NRS) and Wong-Baker Scale. Additionally, the need for medical consultations and any complications arising from PDPH will be recorded.

Comparison of Nebulized Neostigmine/Atropine Versus Lignocaine in Treating Acute Post-dural Puncture Headache Following Subarachnoid Block in Parturient Undergoing Elective Cesarean Section. A Randomized, Clinical Trial.

Post-dural puncture headache (PDPH) is a common and debilitating complication of spinal anesthesia in pregnant patients undergoing cesarean sections, with an incidence ranging from 0.5% to 2% (1). The International Headache Society (IHS) defines PDPH as a headache occurring within 4 days of a lumbar puncture, caused by cerebrospinal fluid (CSF) leakage through the dural puncture (2). Although the exact cause of PDPH is not fully understood, it is thought to occur due to cerebrospinal fluid loss through dural tears, which leads to tension on pain-sensitive intracranial structures and reflex, uncontrolled cerebral vasodilation leading to severe agonizing tension headache (3). Treatment options include proper hydration, maintaining a supine position, caffeine, paracetamol, nonsteroidal anti-inflammatory drugs (NSAIDs). Many adjuvants have been questioned for their therapeutic effectiveness in enhancing conservative medical treatments, with conflicting results (4). For example, sumatriptan, theophylline and dexmedetomidine have been extensively studied. Neostigmine has emerged as a promising pharmacological adjuvant for conservative management. Neostigmine increases the serum level of acetylcholine via inhibition of cholinesterase (5). This action mediates cerebral vasoconstriction via nicotinic receptors, thus antagonizing the unopposed vasodilatation occurred due to dural tear. Lidocaine, on the other hand, can mediate sphenopalatine ganglion block which is responsible for pain signals transmission from the face (6).

Prophylactic Intravenous Injection of Neostigmine Plus Atropine Versus Ketorolac on Post-dural Puncture Headache in Patients Undergoing Infraumbilical Surgeries

Post-dural puncture headache (PDPH) or spinal (or post-spinal) headache is one of the most common side effects of spinal anesthesia, with an incidence of 6-36%. The incidence of this complication was reported to be 76-85% after accidental dural puncture in epidural anesthesia. It usually starts within several hours after spinal anesthesia, but sometimes it can be delayed for up to 2 weeks, which usually resolves within a few days

Contribution of Ondansetron to Preventing Post-Dural Puncture Headaches Following Spinal Anesthesia

A prospective, bicentric, randomized, double-blind controlled study including parturients scheduled for elective caesarean delivery under spinal anaesthesia and randomized and assigned to one of the two groups: Group O ondansetron : receiving Intravenous (IV) ondansetron 0.10 mg/ kg diluted in 5 ml normal saline, 5 min before spinal anesthesia Group C control : receiving IV normal saline 5 ml (control group) 5 min before spinal anesthesia OBJECTIVE : To evaluate the efficacy of ondansetron in preventing post-dural puncture headache after spinal anaesthesia for caesarean section.

Intrathecal Catheter Placement Versus Resiting Epidural Catheter After Dural Puncture in Obstetric Patients

Epidural anesthesia represents the most popular method for pain relief during labour. Unintentional dural puncture (UDP) occurs in 0.4-1.5% of labour epidural analgesia, representing therefore the most common complication. Up to 80% of patients with a UDP may develop a post-dural puncture headache (PDPH). When a UDP occurs, two possible strategies have been proposed in order to ensure analgesia during labour: either resiting the epidural catheter in a different intervertebral space, or inserting an intrathecal catheter. Both strategies proved to equally provide analgesia during labour, but their relative contribution in preventing PDPH is still not known. The primary aim of this multicenter randomized controlled trial is therefore to compare these two strategies in the occurrence of PDPH at 24 hours from the UDP.

Pathophysiological Mechanisms and Implication of Treatment in Postural Puncture Headache

To improve treatment for post dural puncture headache, its pathophysiology needs to be explored. Dural puncture alters CNS dynamics; using advanced MRI, we aim to investigate PDPHs pathophysiology explained by brain movement, cerebral blood flow, CSF dynamics and the effect of epidural blood patch.
