Appraising and highlighting gaps among prophylactic intervention studies for reducing the incidence of postoperative nausea and vomiting in children: a systematic review.

OBJECTIVES: Postoperative nausea and vomiting (PONV) is a leading perioperative morbidity outcome following general anaesthesia. This systematic review aims to identify, appraise and summarise the evidence synthesis studies of prophylactic interventions that reduce the incidence of paediatric PONV, thereby highlighting knowledge gaps and avenues of future research. DESIGN: Systematic review using the AMSTAR-2 (A MeaSurement Tool to Assess Systematic Reviews 2) tool and the ROBIS (Risk Of Bias In Systematic reviews) tool. DATA SOURCES: Seven major databases, including MEDLINE and EMBASE, from inception to 23 September 2022. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Evidence synthesis studies of only randomised controlled trials that explored prophylactic interventions for PONV in children undergoing general anaesthesia. DATA EXTRACTION AND SYNTHESIS: Following screening process by two reviewers, data were extracted from all eligible studies, including demographic parameters and details of interventions. Eligible studies were categorised into 'pharmacological' and 'non-pharmacological' groups and high-risk surgical groups of 'strabismus' and 'tonsillectomy' for qualitative synthesis. RESULTS: There were 20 evidence synthesis reviews (17 meta-analyses, 2 systematic reviews, 1 network meta-analysis): 14 investigated pharmacological PONV prophylaxis in children, 5 investigated non-pharmacological interventions, 1 studied both pharmacological and non-pharmacological interventions. Monotherapy pharmacological prophylaxis agents, for example, dexamethasone (relative risk (RR) 0.49, 95% CI 0.41 to 0.58), 5-hydroxytryptamine (5-HT3) antagonists (OR 0.12, 95% CI 0.07 to 0.20) and α2-adrenoreceptor agonists (dexmedetomidine: RR 0.33, 95% CI 0.21 to 0.54), are more effective than placebo. A combination of pharmacological agents provided superior efficacy to monotherapy, particularly dexamethasone and 5-HT3 antagonists (RR 0.21, 95% credible interval 0.15 to 0.28). Acustimulation practice was consistently favourable in preventing PONV compared with placebo (RR 0.36, 95% CI 0.25 to 0.52). CONCLUSION: Monotherapy pharmacological prophylaxis is more effective than placebo in reducing the incidence of paediatric PONV, with the efficacy increased further by using combination pharmacotherapy. Further research must compare multiple treatment arms of pharmacological and non-pharmacological prophylaxes for PONV to identify the optimal multimodal prophylaxis regimen.

Serum resistin and lipid profile in primigravida females with and without preeclampsia: An analytical cross-sectional study.

OBJECTIVE: To measure and compare the serum levels of resistin and lipid profile parameters in primigravida females with and without preeclampsia. Methods: The analytical cross-sectional study was conducted at the Department of Physiology and Cell Biology, University of Health Sciences, Lahore, Pakistan, from 2018 to 2020, and comprised primigravida females having gestational age 30-36 weeks. Those with preeclampsia constituted group 1, while normotensive females constituted group 2. All the participants were subjected to detailed history and general physical examination. Serum resistin levels were measured by enzymelinked immunosorbent assay, and lipid profile parameters were measured using the colorimetric method. Data was analysed using SPSS 20. RESULTS: Of the 80 women, 40(50%) were in group 1 with mean age 23.07±2.10 years and mean gestation age 33.45±2.30 weeks. There were 40(50%) women in group 2 with mean age 23.02±2.11 years and mean gestational age 34.45±1.75 weeks. Mean serum resistin was significantly higher in group 1 compared to group 2 (p<0.02). Mean levels of lipid parameters were significantly different between the groups (p˂0.05). Conclusion: Preeclampsia was found to be associated with higher levels of resistin and lipid parameters compared to normal pregnancy.

Perioperative clinical practice recommendations for pediatric tonsillectomy: a systematic review.

PURPOSE: Tonsillectomy is one of the most common surgical procedures performed in children. Since most clinical practice guidelines (CPGs) are designed to support surgical decisions, none are specifically designed for the perioperative management of children undergoing tonsillectomy. We aimed to identify and analyze the existing CPGs with recommendations for the perioperative management of children undergoing tonsillectomy by conducting a systematic review. SOURCE: We searched Embase, MEDLINE, MEDLINE ePub Ahead of Print, and CINAHL for relevant articles published from inception to 3 August 2022. The inclusion criteria were: 1) CPG of perioperative recommendations for tonsillectomy under general anesthesia in children, 2) CPG that include at least one evidence-based recommendation, 3) peer-reviewed CPG published in English after 2000. We extracted data on baseline characteristics of each CPG and general recommendations for perioperative interventions or complications. PRINCIPAL FINDINGS: Out of five eligible CPGs, AGREE II and REX confirmed that two CPGs were high quality while only one of the two was recommended for implementation without modifications. Most of the recommendations were for pain management. Acetaminophen was the only medication recommended in all five CPG. Except for the oldest CPG, the CPG all supported of the use of nonsteroidal anti-inflammatory drugs and steroids as a pain adjunct. CONCLUSIONS: Acetaminophen, nonsteroidal anti-inflammatory drugs, and steroids are recommended in the perioperative management of pediatric tonsillectomy. Future CPG should further clarify the safe use of opioids based on severity of obstructive sleep apnea and in the context of opioid-sparing techniques, such as dexmedetomidine, high-dose dexamethasone, and gabapentinoids.

RéSUMé: OBJECTIF: L'amygdalectomie est l'une des interventions chirurgicales les plus courantes pratiquées chez les enfants. Étant donné que la plupart des lignes directrices de pratique clinique sont conçues pour soutenir les décisions chirurgicales, aucune n'est spécifiquement conçue pour la prise en charge périopératoire des enfants bénéficiant d'une amygdalectomie. Notre objectif était d'identifier et d'analyser les lignes directrices de pratique clinique existantes comportant des recommandations pour la prise en charge périopératoire des enfants bénéficiant d'une amygdalectomie en réalisant une revue systématique. SOURCES: Nous avons recherché des articles pertinents dans Embase, MEDLINE, MEDLINE ePub Ahead of Print et CINAHL, publiés depuis la création de ces bases de données jusqu'au 3 août 2022. Les critères d'inclusion étaient les suivants : 1) lignes directrices de pratique clinique comportant des recommandations périopératoires pour l'amygdalectomie sous anesthésie générale chez les enfants, 2) lignes directrices de pratique clinique incluant au moins une recommandation fondée sur des données probantes, et 3) lignes directrices de pratique clinique évaluées par des pairs et publiées en anglais après 2000. Nous avons extrait des données sur les caractéristiques de base de chacune des lignes directrices de pratique clinique et des recommandations générales pour les interventions périopératoires ou les complications. CONSTATATIONS PRINCIPALES: Sur les cinq lignes directrices de pratique clinique admissibles, AGREE II et REX ont confirmé que deux lignes directrices de pratique clinique étaient de haute qualité, tandis qu'une seule des deux a été recommandée pour une mise en œuvre sans modifications. La plupart des recommandations portaient sur la prise en charge de la douleur. L'acétaminophène était le seul médicament recommandé dans les cinq lignes directrices de pratique clinique. À l'exception des lignes directrices de pratique clinique les plus anciennes, les autres ont toutes soutenu l'utilisation d'agents anti-inflammatoires non stéroïdiens et de stéroïdes comme adjuvants pour la douleur. CONCLUSION: L'acétaminophène, les agents anti-inflammatoires non stéroïdiens et les stéroïdes sont recommandés pour la prise en charge périopératoire de l'amygdalectomie pédiatrique. À l'avenir, les lignes directrices de pratique clinique devraient clarifier davantage l'utilisation sécuritaire des opioïdes en fonction de la gravité de l'apnée obstructive du sommeil et dans le contexte des techniques d'épargne des opioïdes, telles que la dexmédétomidine, la dexaméthasone à forte dose et les gabapentinoïdes. ENREGISTREMENT DE L'éTUDE: PROSPERO (CRD42021253374); soumise pour la première fois le 18 juin 2021.

Prophylaxis for pediatric postoperative nausea and vomiting: a scoping review of clinical trials.

PURPOSE: Postoperative nausea and vomiting (PONV) is common in pediatric patients undergoing general anesthesia, and clinicians seek prophylactic interventions to prevent its ill effects on patients as well as its ramifications on perioperative care. We sought to assess the body of evidence around prophylactic strategies, both pharmacologic and nonpharmacologic, targeting pediatric PONV. SOURCE: We searched MEDLINE, MEDLINE ePubs Ahead of Print and In-Process Citations, Embase Classic+Embase, the Cochrane Database of Systematic Reviews, Cochrane CENTRAL (via the Ovid platform), Scopus (Elsevier), Web of Science (Clarivate Analytics), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform, and the International Standard Randomized Controlled Trial Number Registry, from their inception to 23 September 2022. PRINCIPAL FINDINGS: Of 188 clinical trials, 157 (83%) investigated pharmacologic interventions, 25 (13%) investigated nonpharmacologic interventions, and six (3%) investigated mixed pharmacologic and nonpharmacologic interventions. The most common surgeries investigated for pediatric PONV were strabismus surgery (68 trials, 36%) and tonsillectomy or tympanoplasty (45 trials, 23%). Of four measurement tools used to assess PONV in the included trials, the most common was clinical judgement (170 trials, 90%). CONCLUSION: The majority of data in pediatric PONV prophylaxis is based on pharmacologic interventions, with a paucity of research in nonpharmacologic or mixed interventions. Assessing and documenting PONV using tools such as the Baxter Animated Retching Faces Scale or PONV numeric scoring system may help standardize pediatric PONV prophylaxis research moving forward. Furthermore, concurrently assessing pain and adverse effects associated with PONV might further inform our understanding of this complex clinical entity.

RéSUMé: OBJECTIF: Les nausées et vomissements postopératoires (NVPO) sont fréquents chez la patientèle pédiatrique bénéficiant d'une anesthésie générale, et les équipes cliniques recherchent des interventions prophylactiques pour prévenir leurs effets néfastes sur les patient·es ainsi que leurs ramifications sur les soins périopératoires. Nous avons cherché à évaluer l'ensemble des données probantes entourant les stratégies prophylactiques pharmacologiques et non pharmacologiques ciblant les NVPO pédiatriques. SOURCES: Nous avons effectué des recherches dans les bases de données MEDLINE, MEDLINE ePubs Ahead of Print and In-Process Citations, Embase Classic+Embase, la base de données des revues systématiques Cochrane, Cochrane CENTRAL (via la plateforme Ovid), Scopus (Elsevier), Web of Science (Clarivate Analytics), ClinicalTrials.gov, le système d'enregistrement international des essais cliniques de l'OMS et le registre international normalisé des numéros d'essais contrôlés randomisés, depuis leur création jusqu'au 23 septembre 2022. CONSTATATIONS PRINCIPALES: Sur 188 études cliniques, 157 (83 %) portaient sur des interventions pharmacologiques, 25 (13 %) sur des interventions non pharmacologiques et six (3 %) sur des interventions pharmacologiques et non pharmacologiques mixtes. Les chirurgies les plus fréquemment étudiées pour les NVPO pédiatriques étaient les chirurgies de strabisme (68 études, 36 %) et les amygdalectomies ou tympanoplasties (45 études, 23 %). Parmi les quatre outils de mesure utilisés pour évaluer les NVPO dans les études incluses, le plus fréquemment utilisé était le jugement clinique (170 études, 90 %). CONCLUSION: La majorité des données sur les prophylaxies pédiatriques pour prévenir les NVPO sont basées sur des interventions pharmacologiques, avec peu de recherche sur les interventions non pharmacologiques ou mixtes. L'évaluation et la documentation des NVPO à l'aide d'outils tels que l'échelle Baxter Animated Retching Faces Scale ou un système de notation numérique des NVPO peuvent aider à normaliser la recherche sur la prophylaxie pédiatrique des NVPO à l'avenir. De plus, l'évaluation simultanée de la douleur et des effets indésirables associés aux NVPO pourrait éclairer davantage notre compréhension de cette entité clinique complexe.

Leptin and Hyperlipidemia in Primigrivida Preeclamptic Women and Normotensive Women.

OBJECTIVE: To measure and compare serum levels of leptin and lipid profile parameters in primigravida women with PE and normotensive primigravida. STUDY DESIGN: Analytical cross-sectional study. PLACE AND DURATION OF STUDY: Department of Physiology and Cell Biology, University of Health Sciences, Lahore, from 2018 to 2020. METHODOLOGY: Preeclamptic (PE, group A) and normal primigravida (PG, group B) with gestational age 30-36 weeks were recruited from tertiary care hospitals. After written and informed consent, blood samples were taken. Serum was separated and stored at -80oC until processed. CBC and lipid profile of each patient was also done using automated lab machines. Serum levels of leptin were calculated by ELISA. The data was entered and analysed in SPSS version 20. RESULTS: The mean serum levels of leptin (ng/ml) in PE (group A) were significantly raised compared to normotensive PG (group B) at 33.44±12.91 and 4±6.20 respectively (p.
