[Application of two different comfort techniques in extraction of impacted teeth among 60 patients with hypertension].

To compare the effect of two comfort techniques of nitrous oxide/oxygen inhalation and dexmedetomidine combined with flurbiprofen axetil sedation and analgesia in impacted teeth extraction among patients with hypertension.According to the inclusion and exclusion criteria, sixty patients undergoing impacted teeth extraction with hypertension were randomly divided into 2 groups: X group( nitrous oxide/oxygen inhalation, n=30) and Y group(dexmedetomidine combined with flurbiprofen axetil assisted sedation and analgesia, n=30). The following parameters at T0(preoperative), T1(local anesthesia), T2 (surgical operation), and T3 (5 minutes after surgery) were recorded: mean arterial pressure(MAP), heart rate (HR), Ramsay sedation score, VAS pain score. SPSS 20.0 software package was used for statistical analysis.The parameters at each time point between the two groups were not significantly different (P＞0.05). Mood and hemodynamics at T1, T2 and T3 in each group were more stable compared with those at T0(P＜0.05).The two comfort techniques can stabilize the patients' mood, keep the patients' hemodynamics stable, and are safe and effective in extraction of impacted teeth among patients with hypertension.
