“…Regarding age, in a study by Matsumura et al (16), patients in middle and advanced age had a greater increase in SP and DP during molar extractions than younger patients. In agreement with these authors, Nagao et al (17), in dental implant surgery under local anesthesia, showed that SP increased with age.…”

Purpose: This study was conducted to determine the hemodynamic and ventilatory changes during implant surgery with intravenous conscious sedation, and whether preoperative anxiety, gender or age influence these parameters. Patients and Methods: A prospective study carried out between May 2004 and February 2007, on 102 patients treated with dental implants under local anesthesia and conscious intravenous sedation. Patients completed a questionnaire prior to surgery to evaluate preoperative dental anxiety using Corah's scale. The hemodynamic and ventilatory changes were evaluated by monitoring systolic pressure (SP), diastolic pressure (DP), heart rate (HR) and oxygen saturation (SaO2). These values were collected at 5 points during surgery; before commencing the operation (baseline value), during local anesthetic injection, at the moment of incision and raising of a mucoperiosteal flap, during implant placement, and finally at suturing. Intravenous conscious sedation was administered between baseline value and injection of the local anesthetic. Results: The highest SP and DP were recorded at baseline and at suturing. The highest HR was recorded at the moment of incision and raising of the mucoperiosteal flap; the lowest SaO2 was recorded at local anesthetic injection. There was no relationship between hemodynamic and ventilatory values and preoperative anxiety or gender. A greater age was associated with higher SP and lower SaO2, these differences being statistically significant. Conclusions: Most of the cardiovascular and ventilatory changes induced by the implant surgery with intravenous conscious sedation were within normal ranges. The results indicate that midazolam with fentanyl do not produce important hemodynamic and ventilatory changes, being a good association for intravenous conscious sedation in dental implant surgery.

“…Therefore since our study group consisted of a young group of patients with a mean age of 24, this may be the reason why there is a lack of significance in blood pressure and heart rate changes [24].…”

Objective: To investigate perioperative changes in the cardiac parameters of anxiety, which are blood pressure and heart rate, in patients undergoing surgical extraction of third molars. Material and Methods: Patients who reported anxiety before scheduled procedures were monitored for cardiac parameters before, during and after the surgery. The obtained data were analyzed to determine if there is a certain pattern of change within these values in systemically healthy patients. Alterations in selected parameters with regard to duration and difficulty of operation were also studied. IBM SPSS Statistics was used for data analysis. Repeated-measures of analysis of variance (ANOVA), paired samples t-test and Kruskal-Wallis tests were applied and a significance level of 5% was assessed. Results: Difficulty was categorized as minimally, moderately or very difficult in 9, 28 and 3 patients respectively. Mean operation time was 36.18 minutes with a range of 8 to 91 minutes. Operation time showed no variations with different levels of difficulty (p = 0.268). No statistical differences in any of the parameters listed above could be identified. Conclusion: Despite the common belief that dental procedures initiate anxiety, this study reveals that physiological parameters of anxiety show no significant changes over the course of third molar surgery, likewise difficulty and duration of surgery do not cause noteworthy changes in these parameters.

Cuff-Less and Continuous Blood Pressure Monitoring: A Methodological Review

et al. 2017

View full text Add to dashboard Cite

Blood pressure (BP) is one of the most important monitoring parameters in clinical medicine. For years, the cuff-based sphygmomanometer and the arterial invasive line have been the gold standards for care professionals to assess BP. During the past few decades, the wide spread of the oscillometry-based BP arm or wrist cuffs have made home-based BP assessment more convenient and accessible. However, the discontinuous nature, the inability to interface with mobile applications, the relative inaccuracy with movement, and the need for calibration have rendered those BP oscillometry devices inadequate for next-generation healthcare infrastructure where integration and continuous data acquisition and communication are required. Recently, the indirect approach to obtain BP values has been intensively investigated, where BP is mathematically derived through the "Time Delay" in propagation of pressure waves in the vascular system. This holds promise for the realization of cuffless and continuous BP monitoring systems, for both patients and healthy populations in both inpatient and outpatient settings. This review highlights recent efforts in developing these next-generation blood pressure monitoring devices and compares various mathematical models. The unmet challenges and further developments that are crucial to develop "Time Delay"-based BP devices are also discussed.
