Intravenous Hyoscine Butylbromide “Scopolamine” for the Treatment of Extrapyramidal Symptoms: A Case Report

Aim: Extrapyramidal symptoms (EPS) represent motor disturbances frequently induced by medications that impact the dopamine pathways. Although not traditionally employed for addressing EPS, there is potential in using hyoscine butylbromide, an anticholinergic antispasmodic, owing to its mechanism of action that influences cholinergic receptors.
 Presentation of Case: We present a 34-year-old female patient, post-haemorrhoidectomy under spinal anaesthesia, who developed post-lumbar puncture headache with nausea and vomiting. A single dose of metoclopramide (10 mg) led to rapid onset of EPS—tremor, restlessness, and akathisia. Intravenous hyoscine butylbromide (20 mg) resulted in prompt alleviation of EPS.
 Discussion and Conclusion: This case highlights hyoscine butylbromide's potential in managing medication-induced EPS, even in unconventional cases. Rapid symptom resolution and a 7-day follow-up without side effects underscore its short-term efficacy and safety. While broader application and mechanisms necessitate further research, hyoscine butylbromide could be a valuable option for EPS management.

Complications of unintentional dural puncture during labour epidural analgesia: a 10-year retrospective observational study

IntroductionUnintentional dural puncture (UDP) occurs in 0.5–1.5% of labour epidural analgesia cases. To date, little is known about evidence of UDP-related complications. This work aimed to assess the incidence of intrapartum and postpartum complications in parturients who experienced UDP.MethodsThis is a 10-year retrospective observational study on parturients admitted to our centre who presented UDP. Data collection gathered UDP-related complications during labour and postpartum. All women who displayed UDP received medical therapy and bed rest. An epidural blood patch (EBP) was not used in this population. Once asymptomatic, patients were discharged from the hospital.ResultsOut of 7718 neuraxial analgesia cases, 97 cases of UDP occurred (1.25%). During labour, complications appeared in a small percentage of analgesia procedures performed, including total spinal anaesthesia (1.0%), extended motor block (3%), hypotension (4.1%), abnormal foetal heart rate (2%), inadequate analgesia (14.4%), and general anaesthesia following neuraxial anaesthesia failure (33.3% of emergency caesarean sections). During the postpartum period, 53.6% of parturients exhibited a postdural puncture headache, 13.4% showed neurological symptoms, and 14.4% required neurological consultation and neuroimaging. No patient developed subdural hematoma or cerebral venous sinus thrombosis; one woman presented posterior reversible encephalopathy syndrome associated with eclampsia. Overall, 82.5% of women experienced an extension of hospital stay.ConclusionMajor complications occurred in a small percentage of patients during labour. However, since they represent high-risk maternal and neonatal health events, a dedicated anaesthesiologist and a trained obstetric team are essential.No major neurological complications were registered postpartum, and EBP was not performed. Nevertheless, all patients with UDP were carefully monitored and treated until complete recovery before discharge, leading to an extension of their hospitalization.

Prophylactic effect of chamomile on post-dural puncture headache in women undergoing elective cesarean section: A randomized, double blind, placebo-controlled clinical trial

BackgroundPost-dural puncture headache (PDPH) is a common complication after spinal anesthesia, affecting patient recovery. This study evaluated the prophylactic effect of topical chamomile ointment on PDPH in women undergoing elective cesarean section. MethodsIn a randomized, double-blind, placebo-controlled clinical trial 148 pregnant women were randomized into two parallel groups and received 3cc of the chamomile or the placebo ointment on the forehead of the participants 20 minutes before the start of spinal anesthesia, and then 2 and 4 hours after that. The primary outcomes were the incidence rate of headache, and its severity assessed by a numeric rating scale (NRS), while secondary outcomes included analgesic consumption, frequency of nausea/vomiting, and adverse events. ResultsChamomile ointment exhibited significant preventive effects on PDPH incidence compared to placebo. The chamomile group demonstrated lower rates of PDPH at 6 hours (3.5% vs. 7.18%, p = 0.021) and 12 hours (7.6% vs. 20%, p = 0.028) after spinal anesthesia. Analgesic consumption, frequency of nausea/vomiting, and adverse events were comparable between the groups. ConclusionTopical chamomile ointment demonstrated significant preventive effects on PDPH incidence compared to placebo. Chamomile ointment could be a promising adjunctive approach to prevent PDPH, enhancing patient comfort and potentially reducing the need for analgesics. Further investigation is needed to explore its mechanisms and broader applications.

Prophylactic Intravenous Injection of Neostigmine with Atropine versus Ondansetron on Post-dural Puncture Headache Incidence and Severity among Elective Cesarean Section Cases

Incidence and Severity of Post-dural Puncture Headache in Non-obstetric Patients Undergoing Subarachnoid Block.

Background and goal of the study Post-dural puncture headache (PDPH) is a complication of central neuraxial block, either subarachnoid block (SAB) or epidural block. This clinical entity has a wide incidence and is affected by factors such as age, gender, needle gauge, needle shape/type, number of puncture attempts, and previous history of headache. Due to the lack of data in the non-obstetric population, this study assesses the incidence and severity of PDPH after SAB. Materials and methods A prospective observational study was carried out on patients undergoing SAB during the last trimester of 2020. Data were recorded on the day of surgery, 48 hours, and seven days after surgery. Data collected included demographic and medical clinic information, SAB procedure details, and clinical outcomes related to the presence of PDPH. Results and discussion Overall, 143 patients were included (median age: 62 years;53.1% were women (n=76)). Most patients were aged >60 years (55.9%; n=80) and ASA 2 classification (65.0%; n=93). The incidence of PDPH was 21.7% (n=31), and most cases were from inpatient surgery (58.3%, n=21). The incidence of PDPH was 2.5 times higher with the use of 25 gauge compared to the use of the 27 gauge needle and was more prevalent with the use of the Quincke needles. Conclusion Over 20% of patients undergoing SAB experienced PDPH. Previous history of headache, larger gauge, and the Quincke needle use were associated with a higher incidence of PDPH.

COMPARISON OF 25 G WHITACRE AND QUINCKE SPINAL NEEDLES FOR INCIDENCE OF POST-DURAL PUNCTURE HEADACHE

The retrospective study was conducted in tertiary care hospital from June 2022 to December 2022 to compare the severity and incidence of PDPH in patients administered spinal anesthesia for lower limb and lower abdominal surgeries using 25G Whitacre and 25G Quincke needles. A sample size of 140 70 in each of the two groups (group Quincke and group Whitacre) was included in the study. Results showed that 11 (15.7%) patients in group Quincke and 1 (1.4%) patient in group Whitacre had PDPH (P=.009). Females had a higher incidence of PDPH (P=0.018). Of 12 patients, 11 had mild, and 1 had moderate PDPH. 11 patients in group Whitacre and 3 in group Quincke had failed spinal anesthesia. 25G Whitacre spinal needles showed lower incidence and severity of post-dural puncture headache than 25G Quincke spinal needles.

Spinal anesthesia for L5-S1 interlaminar endoscopic lumbar discectomy: a retrospective study

ObjectiveThis study aimed to report our experience with spinal anesthesia (SA) in patients undergoing L5-S1 interlaminar endoscopic lumbar discectomy (IELD) and clarify its advantages and disadvantages.MethodsOne hundred twelve patients who underwent IELD for an L5-S1 disc herniation under SA were retrospectively analyzed. SA with 0.5% ropivacaine was administered using a 27-gauge fine needle. Intraoperatively, the volume and level of SA, surgical time, blood loss, and cardiopulmonary complications were documented. Postoperative data was collected included the number of patients who ambulated on the day of surgery, incidence of complications and were then statistically analyzed.ResultsAnalgesia was complete throughout the entire operation in all patients and no other adjuvant intraoperative analgesic drugs were needed. Mean visual analog scale scores for intraoperative and early postoperative (24 h) pain were 0 and 2.43 ± 1.66. SA was administered at the L3-4 interspace in 34 patients (30.4%) and the L2-3 interspace in 78 (69.6%). Administration was successful with the first attempt in all patients. Mean operation time was 70.12 ± 6.52 min. Mean intraoperative blood loss volume was 20.71 ± 5.26 ml. Ninety-eight patients ambulated on the same day as surgery. Mean length of hospital stay was 24.36 ± 3.64 h. Dural injury without damaging the nerve root occurred in one patient. One patient experienced recurrent disc herniation. Intraoperative hypotension and respiratory distress occurred in five (4.5%) and three (2.7%) patients, respectively. Three patients (2.7%) received postoperative analgesia therapy and two (1.8%) experienced nausea. Two patients (1.8%) developed urinary retention. Spinal headache, cauda equina syndrome, and neurotoxicity did not occur.ConclusionSA can achieve satisfactory pain control for patients undergoing IELD with a low incidence of adverse events. SA may be a useful alternative to local and general anesthesia for IELD surgery. Future randomized controlled trials are warranted to investigate.

THU162 Impact On Visual Function And Optic Nerve Morphology In Early Stages Of Growth Hormone Treatment

Abstract Disclosure: D.G. Braslavsky: None. A.C. Keselman: None. M.G. Ballerini: None. S. Rosenbrock: None. N. Cappa: None. G. Negrete: None. G. Dech: None. M.G. Ropelato: None. S. Gamio: None. I. Bergada: None. Background Current safety of recombinant human growth hormone (rhGH) treatment arises mainly from postmarketing surveillance. Headache is a relatively frequent symptom in children under rhGH. Secondary intracranial hypertension (SIH), is an adverse effect (AE), usually occurring within the first 12 weeks of treatment associated to headaches. Permanent visual defects are the most feared complication. Scarce information exists regarding incidence and natural history of visual impairment under rhGH. Aim To evaluate visual impairment and/or optic nerve affection in children throughout early rhGH treatment. Materials and Methods Prospective interventional study conducted from February 2018 to January 2020. Children ≥4 yr who received rhGH treatment for growth hormone deficiency (GHD), 0.16-0.25 mg/kg/w; Turner syndrome (TS), small for gestational age (SGA), 0.33 mg/kg/w and Prader Willy Syndrome (PWS) 1 mg/m2/d. Patients were assessed at basal, 1, 3, and 6 months of treatment. Each visit included clinical variables (adherence, auxology, AE, presence of headache), serum IGF1, IGFBP3, glucose, insulin, aldosterone, plasma renin activity, electrolytes and ophthalmologic evaluation [fundoscopy, optical coherence tomography (OCT), retinal nerve fiber layer (RNFL), ganglionic eye complex, ocular ultrasound, intraocular pressure (IOP), autorefractometry, biomicroscopy]. Results Sixty patients were enrolled, 12 GHD, 11 ST, 31 SGA, 3 PWS, 3 TBI (23 females), with a median age of 8.08 yrs (ranged 4.24-15). Median height was -2.25 ± 1.05 SDS. Baseline ophthalmologic evaluation was normal. Abnormal ophthalmological findings were observed in 15/60 (25%). Twelve patients showed changes in OCT, spontaneous recovery occurred in 8, whereas persistence or worsening of RNFL thickening lead to an MRI assessment and lumbar puncture (LP) in 4 patients (1 GHD, 2 SGA, 1 ST); only one referred headache. LP revealed opening pressure of 19, 21, 22 and 30 mmHg, respectively, the latter assumed as SIH at the 1st month of treatment. In these four patients, during the findings of ocular abnormalities, they presented a mean IGF1 1.12 ± 1.04 SDS and IGFBP3 -0.02 ± 2.34 SDS. ΔBMI -0.45 ± 0.71 SDS. Prevalence of SIH was 1.6%. All four patients received acetazolamide; median time for RNFL improvement took 4 months (range 4-8). One patient developed post-dural puncture headache. Three had elevated IOP. Along the protocol 19/60 referred headache (26 events). Three of these patients with headaches had abnormal ophthalmological findings (2 mild changes in OCT; 1 elevated IOP). Conclusion We have demonstrated a marked prevalence of abnormal ophthalmological findings upon early rhGH treatment. These observations occurred in the absence of suggestive clinical symptoms, and conversely, headache did not predict SIH. The prevalence of SIH due to rhGH is higher than previously reported.

Incidence and associated factors of post-dural puncture headache among orthopaedic patients after spinal anesthesia: a prospective cohort study.

Post-dural puncture headache (PDPH) is one of a complication of spinal anaesthesia, influenced mostly by various factors including the patient's age, spinal needle size and design and sex. This headache can be severe and debilitating, preventing ambulation and limiting daily living activities. This study assessed the incidence and associated factors of PDPH among patients who received spinal anaesthesia for orthopaedic procedures at the Debre Tabor Comprehensive Specialized Hospital from June to August 2022. Prospective cohort study design was employed using Consecutive sampling method among patients who received spinal anaesthesia for orthopaedics procedure at Debre Tabor Comprehensive Specialized Hospital from June to August 2022. Data were collected by face to face interview and direct observation based on questionnaire. The data were entered to epidata 4.6 and analyzed by SPSS version 20 software. A total 95 patients aged 16-75 was participated in study. Those independent variable that were significant on binary logistic regression at P less than 0.2, were analyzed on multivariate regression, and considered significant association with PDPH at P value less than 0.05. Ninety-five study participants were included in our study of which 19 (20%) had developed PDPH. Among patients who develop PDPH; 9.5% of the patients reported moderate pain while 10.5% experience mild PDPH and 80% of patient has no pain. The BMI and age were found to have significant association with PDPH [(P value 0.018, adjusted odds ratio 8.738, 95% CI, 1.461-52.269) and (P value 0.011, adjusted odds ratio 12.146, 95% CI, 1.753-84.170)], respectively) to PDPH. The incidence of PDPH was found to be higher in Debre Tabor Comprehensive Specialized Hospital. The hospital management and the anaesthetists should minimize the magnitude of by strictly following different preventive strategies.

Decompressive Craniectomy in Postpartum Cortical venous Thrombosis Masquerading as Postspinal Headache: What the Obstetrician should know - A Case Report

Introduction: Cerebral venous sinus thrombosis is commonly seen during pregnancy or in the postpartum period due to multiple physiological changes resulting in an altered state of homeostasis and a hypercoagulable state. Cortical vein thrombosis is a subgroup of cerebral venous thrombosis where there is an involvement of the superficial cerebral veins and may occur with or without coexisting sinus venous thrombosis. Early identification of the diagnosis is of utmost importance to reduce morbidity and mortality. Differentiation from postspinal headache may be difficult until the occurrence of neurological features and a high level of suspicion for this condition is required. Contrast magnetic resonance imaging venography or computed tomography venography can confirm the diagnosis. Methods: We report a case of postpartum cortical venous thrombosis with malignant cerebral sinus venous thrombosis (CSVT). Results: The patient was managed with a lifesaving decompressive craniectomy (DC) procedure and anticoagulants with a favorable response. Conclusion: Obstetricians should be aware of this medical complication of pregnancy and of its management. Medical treatment with anticoagulants is the mainstay of therapy. Patients with malignant CSVT presenting with rapid and severe neurological decline carry a high mortality, and early DC in this subgroup can be lifesaving. Contraceptive agents containing estrogens should not be administered in patients with a previous history of CSVT, and prophylactic low-molecular-weight heparin should be administered throughout a subsequent pregnancy and continued into the puerperium.

Bilateral Greater Occipital Nerve Block; Distal Versus Proximal Approach for Postdural Puncture Headache: A Randomized Clinical Trial

BACKGROUND: One of the common neuraxial anesthesia complications is postdural puncture headache (PDPH). Greater occipital nerve block (GONB) is a simple and safe maneuver with a faster onset than other treatment modalities. OBJECTIVES: Our work aims to compare the pain-relieving effect between distal and proximal ultrasound (US)-guided bilateral GONBs for PDPH. STUDY DESIGN: A randomized, double-blinded study. SETTING: Aswan University Hospital, Egypt. METHODS: The study included 50 patients of both genders, aged 20 to 60 years, who had PDPH with a sitting Numeric Rating Scale (NRS-11) >= 4. Patients were randomized into 2 equal groups. Group D received a US-guided distal bilateral GONB (at the superior nuchal line level). Group P received a US-guided proximal bilateral GONB (at the second cervical vertebra level). Three milliliters of isobaric bupivacaine 0.5% and 4 mg dexamethasone were injected in both blocks. RESULTS: There was a significant decrease in lying down and sitting NRS-11 at 10 minutes, 6, 12, 24, 36, and 48 hours after the intervention compared to before the intervention in both groups. Only sitting NRS-11 was significantly lower in group P than group D in all measurements after the intervention. Success rate (sitting NRS-11 < 4) at 24 hours was 60% in group D and 84% in group P, with an insignificant difference. The total 48-hour paracetamol and tramadol consumption was significantly lower in group P than in group D (P = 0.038 and 0.036, respectively). Transient cervicalgia occurred in 8% of each group. LIMITATIONS: The small number of cases to prove the secondary outcomes and the absence of a control group. CONCLUSIONS: US-guided proximal and distal GONBs were minimally invasive, simple, and effective ways to treat PDPH, with the superiority of proximal GONB in alleviating PDPH.

Postdural Puncture Headache, Subdural Hematoma, and Sixth Cranial Nerve Palsy Lumbar Following Spinal Drain, Resolved with Epidural Blood Patch: Case Report

BACKGROUND: Postdural puncture headache (PDPH) is a known potential complication of lumbar drain placement. Data regarding incidence of PDPH after lumbar drain placement varies, with a range of 0% to 47%. Furthermore, spinal drain placement has been associated with a significantly increased risk of debilitating neurologic complications. CASE REPORT: In this article, we describe the case of a patient who developed PDPH, subdural hematoma, and abducens nerve palsy after lumbar drain. The patient was treated successfully with epidural blood patch. To our knowledge, this is the first case report of a patient who developed all 3 of these complications following spinal drain placement. CONCLUSION: Dural puncture, whether accidental or purposeful, carries a risk of multiple serious neurological sequelae. After spinal drain placement, close monitoring for symptoms of intracranial hypotension should ensue with a plan for treatment in the event the patient develops a PDPH or other neurologic sequelae. KEY WORDS: Epidural blood patch, headache, postdural puncture headache

Prophylactic Epidural Blood Patch or Prophylactic Epidural Infusion of Hydroxyethyl Starch in Preventing Post–Dural Puncture Headache - A Retrospective Study

BACKGROUND: Post–dural puncture headache (PDPH) is particularly likely to happen in patients under obstetric care due to an unintentional dural puncture (UDP). There is as yet no ideal strategy for preventing UDP-induced PDPH. OBJECTIVES: The primary objective of this study was to assess whether a prophylactic epidural blood patch (EBP) or prophylactic epidural infusion of hydroxyethyl starch (HES) is effective in preventing PDPH for parturients with UDP compared with conservative treatments. STUDY DESIGN: Retrospective analysis from a single center’s inpatient data. SETTING: Department of Anesthesiology at a single center. METHODS: A retrospective study was conducted of a single center’s inpatient data from January 2017 through March 2020. The study included parturients with UDP during neuraxial anesthesia. The interventions of UDP included conservative treatment, prophylactic EBP, and prophylactic epidural infusion of HES. The incidence of PDPH, the use of intravenous aminophylline, therapeutic EBP, symptom onset, duration of headache, and duration of hospital stay were compared. RESULTS: A total of 85 patients were analyzed. The incidences of PDPH were 84%, 52.6% and 54.5% with conservative, prophylactic EBP, and prophylactic epidural HES treatments, respectively. Compared with the conservative treatment, prophylactic EBP and prophylactic epidural HES treatment significantly reduced the incidence of PDPH (P < 0.05). No significant difference was found between the prophylactic EBP and prophylactic epidural HES groups. Compared with the conservative treatment group, therapeutic EBP was significantly less used in the prophylactic EBP and prophylactic epidural HES groups (P < 0.05). Prophylactic EBP shortened the length of hospital stay of parturients with UDP (P < 0.05) while prophylactic epidural HES showed no statistical difference compared with conservative treatment. No severe complications, such as central nervous system and puncture site infection or nerve injury, were found in those patients. LIMITATIONS: Retrospective nature and single center data with a relatively small sample size. CONCLUSIONS: Prophylactic management with EBP and epidural infusion of HES has an effect in preventing the occurrence of PDPH; prophylactic EBP significantly shortened hospital stay length in parturients with UDP. KEY WORDS: Unintentional dural puncture, epidural blood patch, hydroxyethyl starch, post–dural puncture headache, parturient

Secondary headaches in pregnancy and the puerperium.

Headache during pregnancy can be due to primary causes such as migraine but can also be a presenting symptom of secondary causes including life threatening conditions. This is a minireview of secondary causes of headache during pregnancy and the puerperium. Unique alterations in physiological and vascular functions as well as in the coagulation pathway which occur during pregnancy increase the risk of most of these secondary conditions which include preeclampsia, eclampsia, hemorrhagic stroke, cerebral venous, sinus thrombosis, reversible cerebral vascular syndrome, and posterior reversible encephalopathy. Marked increase in progesterone level in pregnancy is also associated with the growth of tumors such as meningiomas, as 70% of these tumors are positive for progesterone receptors and increase in size can lead to headache along with other neurological symptoms. Hemodynamic changes can lead to the growth of meningiomas as well. Although hormone producing pituitary tumors are usually not conducing to pregnancy, women with known pituitary tumors who do get pregnant may become symptomatic during pregnancy and develop secondary headache. Another rare cause of secondary headache during pregnancy is pituitary apoplexy. Although its occurrence is uncommon, it needs to be properly recognized and treated to avoid endocrine and visual complications. Other rare entities with increased incidence during the puerperium such postdural puncture headache will be also discussed. In summary, new onset headache during pregnancy deserves special attention because in the absence of proper recognition and treatment, secondary headache disorders can endanger the life of the mother and the fetus.

Sphenopalatine ganglion block with or without greater occipital nerve block for treatment of obstetric post-dural puncture headache after spinal anesthesia: randomized controlled trial

BackgroundConservative treatments of post-dural puncture headache (PDPH) may be unsuccessful, and the relief that is provided is frequently insufficient. This study aimed to meticulously explore the analgesic efficacy of the sphenopalatine ganglion (SPG) block when administered alone or in conjunction with the greater occipital nerve block (GONB) for the purpose of treating PDPH and with the aid of transcranial Doppler (TCD) to evaluate the cerebral hemodynamics before and after the block.This study was conducted on 63 women with post-partum PDPH randomized into the following: control group (Group C = 21 participants), received conservative management; SPG block group (Group S = 21 participants), received conservative management with SPG block; and combined nerve and ganglion block group (Group NAG = 21 participants), received conservative management with SPG block and ultrasound guided GONB. Visual analog score (VAS), modified Lybecker score, and transcranial Doppler (TCD) measures were used to determine PDPH severity at 0 (baseline), 1, 6, and 24 h. Additionally, the three groups’ needs for EBP were noted.ResultsVAS and modified Lybecker scores at 1, 6, and 24 h were statistically significantly lower in S and NAG groups compared to the control group with no statistically significant difference between S and NAG groups. With TCD, the mean velocity (MV) was significantly lower at 1, 6, and 24 h compared to baseline reading in both S and NAG groups. Also, the pulsatility index (PI) was statistically higher at 1, 6, and 24 h compared to baseline readings in S and NAG groups. There was no statistically significant difference regarding the need for EBP.ConclusionsIn terms of headache relief or the need for EBP, there is no difference between individual SPG block or combined SPG block and GONB in the treatment of PDPH.

Risk factors for recurrence of post-dural puncture headache following an epidural blood patch: a retrospective cohort study

IntroductionPost-dural puncture headache (PDPH) occurs in 0.38–6.3% of neuraxial procedures in obstetrics. Epidural blood patch (EBP) is the standard treatment but fails to provide full symptom relief in 4–29% of cases. Knowledge of the risk factors for EBP failure is limited and controversial. This study aimed to identify these risk factors. MethodsWe performed a retrospective cohort study using electronic records of 47920 patients who underwent a neuraxial procedure between 2001 and 2018 in a large maternity hospital in Switzerland. The absence of full symptom relief and the need for further treatment was defined as an EBP failure. We performed univariate and multivariate analyses to compare patients with a successful or failed EBP. ResultsWe identified 212 patients requiring an EBP. Of these, 55 (25.9%) had a failed EBP. Signs and symptoms of PDPH did not differ between groups. While needle size and multiple pregnancies were risk factors in the univariate analysis, mostly those related to the performance of the EBP remained significant following adjustment. The risk of failure increased when the epidural space was deeper than 5.5 cm (OR 3.08, 95% CI 1.26 to 7.49) and decreased when the time interval between the initial dural puncture and the EBP was >48 h (OR 0.20, 95% CI 0.05 to 0.83). ConclusionPersistence of PDPH following a first EBP is not unusual. Close attention should be given to patients having their EBP performed <48 h following injury and having an epidural space located >5.5 cm depth, as these factors are associated with a failed EBP.

Impact of Primary Cesarean Section on Grand Multiparous Women

Background: Grand multiparty is common obstetrical problem, in Sudan large families is desirable for cultural and religious backgrounds and higher incidence of grandmultipra is expected, the risk factors associated with adverse maternal outcomes have yet to be adequately investigated among grand multiparity need to delivered by primary cesarean section. Objective: The main objective was to determine impact of primary cesarean section on grand multiparous, it is indications and complications. Methodology: It was a descriptive prospective cross-sectional hospital-based study conducted at Omdurman Maternity Hospital during period October 2016 to March 2017. An interview questionnaire was used for data collection. Demographic and clinical data concerning personal history, parity, indications of primary cesarean section, type of Cs, maternal complication and neonatal complications were recorded. Also, multiparous less than five delivery, previous lower segment caesarean section, known medical disorders except anemia and twin pregnancy were excluded. Results: During the study period total of 113 grand multipara included, incidence of primary cesarean section in grand multipara was 10%. Indication in our study 22.1% due to malpresentation, fetl distress 15% and prolonged first stage 13.4%, prolonged second stage 12.4% and antepartum haemorrhage 11.5%. Postpartum haemorrhage developed in 9.7%, hysterectomy 1.8%, uterine tear 5.4% bladder injury fetal laceration 3.6%, spinal anesthesia headache 7%, post-partum pyrexia 5.3%, sepsis 4.4%, urinary tract infections were 2.7%. Conclusion: The finding in this study showed 10% incidence of primary cesarean section in grandmultipra. The most indications of primary cesarean section in grandmultipra malpresentation, fetal distress, prolonged first and second stage of labour. Most CS were emergency.

Prophylactic cerebrospinal fluid drainage and spinal cord ischemia in thoracic and thoracoabdominal endovascular procedures: a systematic review and meta-analysis.

Spinal cord ischemia (SCI) is one of the most devastating complications of thoracic endovascular aortic repair (TEVAR). Prophylactic cerebrospinal fluid drainage (CSFD) has been shown to decrease the risk of SCI in open thoracic aortic procedures; however, its utility in TEVAR remains uncertain. This systematic review and meta-analysis aim to determine the role of prophylactic CSFD in preventing SCI in TEVAR. A literature search of five databases was performed and all studies published before September 2022 that reported SCI rates in TEVAR patients undergoing prophylactic CSFD were included. A random effects meta-analysis of means or proportions was performed for single-arm data. Odds ratios (ORs) with 95% confidence intervals (CIs) were reported for comparisons between groups. A total of 4,793 patients undergoing TEVAR from 40 studies were included. The mean age was 68.8 years and 70.9% of patients were male. The overall SCI rate was 3.5%, with a 1.3% rate of immediate SCI and a 1.9% rate of delayed SCI. There were no significant differences in SCI rates between prophylactic CSFD patients and non-drained patients. Routine CSFD did not have a significant impact on SCI rates compared to non-drained patients. There was an increased rate of transient SCI with selective CSFD compared to non-drained patients (OR 2.08; 95% CI: 1.06-4.08; P=0.03). The most common drain-related complication was spinal headache (4.3%). The major complication rate was 1.6%, of which epidural or spinal hematoma (0.9%) was the most common, followed by intracranial or subdural hemorrhage (0.8%) and paraparesis or paraplegia (0.8%). This study found no significant difference in SCI rates between prophylactic CSFD patients and their non-drained counterparts. CSFD is associated with a small but non-negligible risk of serious complications. Multi-center randomized controlled trials (RCTs) are warranted to help stratify the risk of both SCI and CSFD-related complications in patients undergoing endovascular aortic procedures.

Addition of Neostigmine and Atropine to Conventional Management of Postdural Puncture Headache in Patients Undergoing Lower Abdominal Surgeries

Abstract Background Postdural puncture headache (PDPH) is a complication of spinal anesthesia or lumbar puncture and is an unpleasant experience for the patient as well as the anesthetist. It is thought to result from meningeal traction related to low cerebrospinal fluid (CSF) pressure or cerebral vasodilation as an indirect effect of decreased CSF pressure. Neostigmine is a reversible inhibitor of the enzyme cholinesterase, which results in an increased concentration of the neurotransmitter acetylcholine. It produces cholinergic-mediated analgesia and has been used as an adjunct analgesic postoperatively. Neostigmine can pass through the choroid plexus but not the blood–brain barrier, the central effect of both neostigmine and atropine influence both CSF secretion and cerebral vascular tone which are the primary pathophysiological changes in PDPH. Objective Assess the effectiveness of postdural anesthesia with addition of Neostigmine and Atropine versus conventional postdural anesthesia. Patients and Methods A 90 patients were included in our prospective randomized controlled double-blind study that was conducted at Ain Shams University Hospitals for 4 months on patients who fulfilled the inclusion criteria: patients with ASA Grade I &amp; II, aged from (18 to 40) years old and scheduled for cesarean section. All patients aged &amp;gt;18 or &amp;lt;40, body weight &amp;gt;50, ASA III, IV, patients with uncontrolled chronic diseases such as hypertension, cardiac, renal, hepatic, cerebral diseases and peripheral vascular diseases, patients with history of PDPH, chronic headache, cluster headache, migraine, convulsions, cerebrovascular accident, signs of meningismus, preeclampsia, eclampsia coagulopathy, and previous neurological diseases and patients with history of bronchial asthma were excluded. Patients were divided into 2 groups: Group I (experimental group): neostigmine and atropine and Group II (placebo group): Saline placebo. Results The results of this study showed that incidence of postoperative headache was significantly lower among the intervention group, furthermore, VAS was significantly lower in the experimental arm versus placebo one. However, there was no significant difference regarding demographic, vital signs, and need for post-operative analgesia. The presented study showed that there is statistically non-significant difference between the studied groups regarding age, weight, and height and body mass index. There is statistically non-significant difference between the studied groups regarding duration of surgery. Conclusion After demonstrating many management options for post dural puncture headache (PDPH), in this study, we tried to prove the value of the use of neostigmine as a new management option that looks promising to alleviate the symptoms of such distressing condition. The current study results proved that the drug reduced the number of cases that experienced (PDPH) after spinal anesthesia for lower segment caesarean section, and how it prevent &amp;control headache. A combination of neostigmine and atropine are effective in managing PDPH by reducing the associated VAS score and preventing persistence of headache.

Flouroscopic Versus Conventional Epidural Blood Patch in Obstetrics: A Retrospective Cohort Study

(Acta Anaesthesiol Scand. 2022;66:563–568) Within obstetric anesthesia, accidental dural puncture is the most prevalent complication, contributing to a postdural puncture headache (PDPH) in 60% to 70% of patients. Currently, epidural blood patch (EBP) is a standard treatment for PDPH, yet questions regarding optimal blood volume, effectivity, and others remain. EBP can be done through conventional EBP (C-EBP) or through fluoroscopy-guided EBP (F-EBP) methods. The aim of this study is to determine headache intensity at hospital discharge, compare blood volumes used in C-EBPs versus F-EBPs, and analyze the outcomes of both treatment methods.
