Intravenous sedation in dental implant surgeries: A systematic review of hemodynamic effects

Background. The main objective of thissystematic review wasto identify the hemodynamic effects of intravenous sedatives used in dental implant surgeries. Methods. Embase, PubMed, ProQuest, Scopus, Ovid, and Cochrane databases were searched with no limitations. Of 59 studies obtained, 50 studies were excluded due to incompatibility with the subject. The remaining studies were reviewed in full text and assessed for the risk of bias individually. The included studies were reviewed by the research team, and the necessary data were extracted. Results. Four studies were finally included. Two of the studies compared local anesthesia and intravenous sedation, while the other two compared the consequences of different types of intravenous sedation. By comparing the hemodynamic effects, the systolic and diastolic blood pressure and the heart rate data were collated. Midazolam was the most frequently used intravenous sedative, and Dexmedetomidine affected hemodynamics the most. Conclusion. Intravenous sedation leads to decreased heart rate and blood pressure. Better hemodynamic outcomes improve the patients’ cooperation by decreasing stress and anxiety. Dexmedetomidine seems to be the first choice for intravenous sedation.
