RESUMO
BACKGROUND AND AIM: Breech presentation is a condition that occurs in rare cases in pregnancy. Although guidelines recommend a cesarian section or an external cephalic version in case of breech, alternative procedures like acupuncture, are also available. Information on this approach is mostly found by patients through social media; we aimed to study content quality and the reliability of information present on YouTube™ (Google LLC, Mountain View, California, United States), one of the most popular. METHODS: Two gynecologists and an anesthesiologist, who was qualified as an acupuncturist, rated the reliability and the content quality of 23 of the first 100 results from YouTube. Normal data distribution was tested with the Shapiro-Wilk test. General features of videos, reliability, and content quality were compared with the Wilcoxon-Mann-Whitney test (continuous variables) and the Chi-square test (categorical variables). All tests were two-sided, and the statistical significance level was determined at p<0.05. RESULTS: Concerning reliability, all videos were rated poorly while only one was judged as sufficiently high in quality content. Lower scores in terms of reliability and content quality resulted from the reviewers' evaluation with no videos reported as suggestable to patients. Two videos were considered fit to be suggested to patients by the gynecologist reviewers. CONCLUSIONS: Information about the role and the success rate of acupuncture for converting breech presentation found on YouTube are poorly reliable, low-quality, and not valid for patients. It should be a physician's duty to provide correct information to patients.
RESUMO
Background: Different techniques have been analyzed to reduce the risk of perineal trauma during labor.Objective: To evaluate whether perineal massage techniques during vaginal delivery decreases the risk of perineal trauma.Search strategy: Electronic databases (Medline, Prospero, Scopus, ClinicalTrials.gov, Embase, ScienceDirect, the Cochrane Library, SciELO) were searched from their inception until February 2018. No restrictions for language or geographic location were applied.Selection criteria: We included all randomized controlled trials (RCTs) comparing the use of perineal massage during labor (i.e. intervention group) with a control group (i.e. no perineal massage) in women with singleton gestation and cephalic presentation at ≥36 weeks. Perineal massage was defined as massage of the posterior perineum by the clinician's fingers (with or without lubricant). Trials on perineal massage during antenatal care, before the onset of labor, or only in the early part of the first stage, were not included.Data collection and analysis: All analyses were done using an intention-to-treat approach. The primary outcome was severe perineal trauma, defined as third and fourth degree perineal lacerations. Meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce summary treatment effects in terms of either a relative risk (RR) with 95% confidence interval (CI).Main results: Nine trials including 3374 women were analyzed. All studies included women with singleton pregnancy in cephalic presentation at ≥36 weeks undergoing spontaneous vaginal delivery. Perineal massage was usually done by a midwife in the second stage, during or between and during pushing time, with the index and middle fingers, using a water-soluble lubricant. Women randomized to receive perineal massage during labor had a significantly lower incidence of severe perineal trauma, compared to those who did not (RR 0.49, 95% CI 0.25-0.94). All the secondary outcomes were not significant, except for the incidence of intact perineum, which was significantly higher in the perineal massage group (RR 1.40, 95% 1.01-1.93), and for the incidence of episiotomy, which was significantly lower in the perineal massage group (RR 0.56, 95% CI 0.38-0.82).Conclusions: Perineal massage during labor is associated with significant lower risk of severe perineal trauma, such as third and fourth degree lacerations. Perineal massage was usually done by a midwife in the second stage, during or between and during pushing time, with the index and middle fingers, using a water-soluble lubricant.
