AI Article Synopsis
- The study aimed to compare the safety and effectiveness of high dose versus low dose oxytocin for labor augmentation.
- Eight randomized clinical trials involving 3,154 patients were analyzed, focusing on outcomes like cesarean delivery rates and uterine hyperstimulation.
- Results showed that high dose oxytocin didn't significantly reduce cesarean deliveries or increase spontaneous vaginal deliveries, while low dose was associated with fewer complications and a shorter labor duration.
Article Abstract
Objectives: To compare the safety and efficacy between high dose and low dose oxytocin administration for labor augmentation.
Methods: We searched for the available studies during March 2020 in PubMed, Cochrane Library, Scopus, and ISI Web of science. All randomized clinical trials (RCTs) that assessed safety and efficacy of high dose vs. low dose oxytocin for labor augmentation were considered. The extracted data were entered into RevMan software. Dichotomous and continuous data were pooled as odds ratio (OR) and mean difference (MD) respectively, with the corresponding 95% confidence intervals (CI). Our main outcomes were cesarean delivery rate, spontaneous vaginal delivery rate, uterine hyperstimulation and tachysystole, and labor duration from oxytocin infusion.
Results: Eight RCTs with 3,154 patients were included. High dose oxytocin did not reduce cesarean delivery rate compared to low dose oxytocin (OR=0.76, 95% CI [0.52, 1.10], p=0.15). After solving the reported heterogeneity, high dose oxytocin did not increase the rate of spontaneous vaginal deliveries vs. low dose oxytocin (OR=1.06, 95% CI [0.84, 1.32], p=0.64). Low dose oxytocin was linked to a significant decline in uterine hyperstimulation and tachysystole (p>0.001). A reduction in labor duration was found in high dose oxytocin group over low oxytocin regimen (MD=-1.02 h, 95% CI [-1.77, -0.27], p=0.008).
Conclusions: We found no advantages for high dose oxytocin over low dose oxytocin in labor augmentation except in reducing labor duration. Low dose oxytocin is safer as it decreases the incidence of uterine hyperstimulation and tachysystole. More trials are needed to confirm our findings.

Objectives: To evaluate the efficacy and safety of Carbetocin compared to oxytocin in prevention of postpartum hemorrhage (PPH) after low-risk cesarean delivery (CD).
Search Strategy: Screening of Medline, Web Of Science, Scopus, Google scholar, and clinical trials registry till January 2024 using the key words related to carbetocin, blood loss, PPH, Cesarean section and their MeSH terms was done.
Selection Criteria: This study included all RCTs conducted on women with low risk for developing PPH after CD and compared the administration of carbetocin to oxytocin without any language limitation.
Impact of chronic intranasal oxytocin administration on face expression processing in autistic children: a randomized controlled trial using fMRI.

Background: Difficulties with (non-verbal) social communication, including facial expression processing, constitute a hallmark of autism. Intranasal administration of oxytocin has been considered a potential therapeutic option for improving social difficulties in autism, either by enhancing the salience of social cues or by reducing the social stress and anxiety experienced in social encounters.
Methods: We recorded fMRI brain activity while presenting neutral, fearful and scrambled faces, to compare the neural face processing signature of autistic children (n = 58) with that of matched non-autistic controls (n = 38).
Comparison of balloon catheter and oral misoprostol for cervical ripening in women with pre-labor rupture of membranes: A Finnish randomized controlled trial.

Introduction: Pre-labor rupture of membranes (PROM) occurs in about 8% of term pregnancies with over 70% delivering spontaneously within 24 h. However, prolonged PROM increases the risk of chorioamnionitis and neonatal sepsis. While misoprostol and oxytocin are considered safe and effective methods of labor induction, most guidelines do not encourage balloon catheter (BC) use following PROM given concerns about increased risk of chorioamnionitis.

The affective dimension in postsurgical pain is still poorly understood. Since neuropeptide oxytocin (OXT) has been implicated in a broad spectrum of pain and negative emotion, we investigated the potential therapeutic effect of intranasal OXT on postsurgical pain and associated anxiety in a mice model of plantar incision. The role of large conductance Ca(2+)-activated K(+) (BK(Ca)) channels was explored by using behavioral pharmacology experiments.
