Aminophylline 360mg suppositories

Post-dural puncture headache (PDPH) is occasionally an inevitable side effect of neuraxial anesthesia, which can happen after spinal anesthesia or if an accidental dural puncture (ADP) happens during epidural anesthesia. The treatment and prevention options for PDPH differ widely from one institution to another. The management of PDPH is heterogeneous in many institutions because of the absence of clear guidelines and protocols for the management of PDPH. This study aimed to summarize all articles published during the past decade that discussed the treatment or prevention of PDPH. From 2013 to 2023, 345 publications were filtered for all treatment and prevention approaches used for PDPH patients. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines were followed for conducting this systematic review, and 38 articles were included for analysis and review. Existing data come from small randomized clinical trials and retrospective or prospective cohort studies. This review supports the effect of oral pregabalin and intravenous aminophylline in both treatment and prevention. Intravenous mannitol, intravenous hydrocortisone, triple prophylactic regimen, and neostigmine plus atropine combination showed effective and beneficial outcomes. On the other hand, neither neuraxial morphine nor epidural dexamethasone showed promising results. Consequently, the use of neuraxial morphine or epidural dexamethasone for the prevention of PDPH remains questionable. Regarding the posture of the patient and its consequences on the incidence of the headache, lateral decubitus is better than a sitting position, and a prone position is better than a supine position. Smaller non-cutting needles play a role in avoiding PDPH. Minimally invasive nerve blocks, including sphenopalatine ganglion or greater occipital nerves, are satisfyingly effective. Epidural blood patches remain the more invasive but the gold standard and ultimate solution in patients resisting medical therapy. This study highlights the need for larger research to define the best approach to prevent and treat PDPH.

Background: Apnea of prematurity affects at least 85% of infants born before 34 weeks' gestation and represents a significant clinical challenge in neonatal intensive care. Methylxanthines, including caffeine, theophylline, and aminophylline, have emerged as the primary pharmacological intervention for this condition. Objective: To conduct a comprehensive systematic review of the use of methylxanthine in the treatment and prevention of apnea episodes in preterm infants, evaluating efficacy, safety, and long-term outcomes. Methods: We searched multiple databases including PubMed, Embase, Web of Science for randomized controlled trials, retrospective studies, or case-control studies of methylxanthine effects in preterm apnea. Risk of bias was assessed using the Cochrane Risk of Bias tool. Results were summarized narratively and grouped by methylxanthine type, study design, and primary outcomes (reduction in frequency and severity of apnea episodes, success of extubation, risk of bronchopulmonary dysplasia). Results: Twenty-five studies (n = 4599 preterm infants) were included. The landmark Caffeine for Apnea of Prematurity (CAP) trial (n = 2006) demonstrated that caffeine therapy significantly reduced bronchopulmonary dysplasia (36.3% vs. 46.9%, adjusted OR 0.63) and facilitated the earlier discontinuation of positive airway pressure (median 1 week earlier). Studies with a smaller number of cases have consistently demonstrated the efficacy of methylxanthines in reducing the incidence of bronchopulmonary dysplasia and apneic episodes and in supporting successful extubation. Long-term follow-up at 11 years showed improved pulmonary function (FEV1 z-score -1.00 vs. -1.53). Discussion: Limitations of this review include heterogeneity in outcome definitions, small sample sizes in early studies, and the dominance of evidence from the CAP trial. Methylxanthines, particularly caffeine, are an evidence-based intervention used for apnea of prematurity, with demonstrated benefits that extend beyond reducing the frequency and severity of apnea episodes, including decreasing the risk of bronchopulmonary dysplasia as well as reducing the need for mechanical ventilation. No external funding was received for this review. No registration record exists for this systematic review.

IntroductionPediatric critical asthma is one of the most common pediatric illnesses in children admitted to the pediatric ward and pediatric intensive care unit (PICU). Adjunct intravenous (IV) bronchodilators are often used when initial management with systemic corticosteroids and inhaled short-acting beta agonists (SABA) fail to provide improvement in a patient's clinical condition. While the recent guidelines gave recommendations for the use of different IV bronchodilators compared to placebo, it did not include ranking on which one should be used as first-line or second-line agent. The aim of this network meta-analysis is to determine the effect of IV bronchodilators on patient-centered outcomes and rank medications based on their effectiveness in these outcomes.MethodsA systematic review was conducted using three databases MEDLINE, Embase, and CINAHL to identify randomized control trials examining the use of IV magnesium sulfate (MgSO4), IV methylxanthines (aminophylline or theophylline), IV SABA (salbutamol, terbutaline) in pediatric critical asthma patients. Bayesian network metanalytic framework was used to compare the interventions. Results are reported as odds ratio (OR) or mean difference (MD) and 95% Credible Interval (CrI).ResultsTwelve trials (n = 852) were included in the network meta-analysis. Largest reduction in hospital length of stay (LOS), PICU admission, and PICU LOS were noted with IV MgSO4; (MD: -3.1 days, 95% CrI: -6.9 days to 0.13 days), (OR 0.21; 95% CrI 0.02, 1.3), and (MD: -4.0 days, 95% CrI: -7.1 days to -1.2 days) respectively. IV MgSO4 was ranked first in three outcomes of interest with Surface Under the Cumulative Ranking curve (SUCRA) of 0.884 for hospital LOS, 0.919 for PICU admission, and 0.957 for PICU LOS. For preventing intubation, IV SABA was ranked the highest (SUCRA 0.995), but the only study with IV SABA had zero intubation events. In a sensitivity analysis that excluded studies with zero events, the intubation rate was lowest with IV MgSO4 (OR 0.10; 95% CrI 0.003, 0.88) and it was ranked the best treatment (SUCRA 0.921).ConclusionsIn this network meta-analysis comparing different IV adjunct bronchodilators, IV MgSO4 was ranked first followed by IV SABA, and then IV methylxanthines. Given these findings and the favorable safety profile, ease of use, and low cost, IV MgSO4 appears most promising the first adjunct IV bronchodilator, however, further large high-quality trials are still needed before it can be endorsed as routine first-line agent.
