Background: Although, some clinical trials investigated the maternal and neonatal effect of fentanyl as a premedication before induction of general anesthesia in cesarean section, to the best of our knowledge, there is no systematic review to summarize these results. Objectives: The present systematic review and meta-analysis evaluated the maternal and neonatal effect of intravenous fentanyl as a premedication before induction of general anesthesia in cesarean section. Methods: The databases of Pubmed, Embase, Scopus and Cochrane library were searched till July 2017 to identify randomized clinical trials which evaluated the effects of intravenous fentanyl as a premedication before induction of general anesthesia compared with placebo on neonate first and fifth minute Apgar score and maternal heart rate and mean arterial pressure (MAP) in cesarean section. Standard Mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. Results: The present systematic review and meta-analysis consisted of three clinical trials including 180 women in labor. Considering the results of meta-analysis, there is no significant differences between fentanyl and placebo in the case of Apgar score at 1 minute; however, the Apgar score of 5 minutes was significantly lower in fentanyl group compared with placebo (SMD -0.68, 95%CI: - 0.98, -0.38, p<0.001). In the term of maternal hemodynamics, the heart rate (SMD -0.43, 95%CI: - 0.72, -0.13, p=0.004) and MAP (SMD -0.78, 95% CI: -1.09, -0.48, p<0.001) in fentanyl group were significantly lower compared with placebo group. Conclusion: The present meta-analysis showed that using intravenous fentanyl as a premedication before induction of general anesthesia had adverse effects on neonate Apgar score. However, it had positive effects on preventing adverse consequences of intubation on maternal hemodynamics.

Abstract Background Photobiomodulation is widely being used to improve the wound healing process in dentistry and a vast majority of studies have proven its benefits. But there are plenty of knowledge gaps according to the optimal laser characteristics which should be used to maximize the healing effects of lasers. The goal of this systematic review and meta-analysis was to determine the effect of photobiomodulation (PBM) as an adjunctive treatment to periodontal therapies to evaluate secondary intention gingival wound healing and post-operative pain. Methods Five databases (PubMed, Embase, Scopus, ProQuest, and Web of Sciences) were searched up to November 30, 2020, for clinical trials that reported the result of the application of PBM on secondary gingival healing wounds and post-operative pain and discomfort after periodontal surgeries. Two independent reviewers selected the eligible studies and the outcomes of interest were extracted. The quality of eligible studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. Results Ultimately, twelve studies were included in this review. The application of PBM as an adjunct to periodontal surgeries resulted in a significant improvement in wound healing indices. The Landry wound healing index at the 7th post-operative day was significantly improved (SMD = 1.044 [95% CI 0.62–1.46]; p < 0.01) in PBM + surgery groups compared to the control groups. There was also a statistically significant increase in the complete wound epithelialization (RR = 3.23 [95% CI 1.66–6.31]; p < 0.01) at the 14th post-operative day compared to the control groups. The methods used to assess the post-operative pain were heterogeneous, and therefore the results were limited which made the meta-analysis for post-operative pain assessment not possible. Conclusion Based on the results of this review, PBM can be effectively used as a method to improve secondary intention wound healing. High-quality randomized clinical trials, however, are needed in the future to identify the optimal PBM irradiation parameters and the effect of PBM on post-operative pain.
