Objective To study the application effect and adverse
reactions of dexmedetomidine in daytime hysteroscopic anesthesia. Methods A total of 360
hysteroscopic anesthesia patients in Xiamen First Hospital Affiliated to Xiamen
University from October 2019 to October 2020 were divided into two groups with
the random number table method with 180 cases in each group. In the control
group, the age was (34.74±5.12) years old, and the body weight was (57.52±6.58)
kg; in the study group, the age was (35.32±4.51) years old, and the body weight
was (56.02±7.01) kg. The control group was given propofol combined with
sevoflurane, and the study group was given dexmedetomidine combined with
sevoflurane. The vital signs before induction of anesthesia (T0), during
induction (T1), during operation (T2), and while awake (T3), awakening,
recovery score after anesthesia, adverse reactions, Ramsay sedation score,
Observer's Assessment of Alertness/Sedation Scale (OAA/S) score, and Numerical
Rating Scale (NRS) score were observed. Independent sample t test, paired t test,
and χ2 test were used for
statistical analysis. Results There were no statistically significant differences in the operation
time, incidences of hypertension, tachycardia, and bradycardia, and heart rate
(HR), mean arterial pressure (MAP), and oxygen saturation (SpO2) at
T0 between the two groups (all P>0.05).
There were statistically significant differences in the HR, MAP, and SpO2 between T1, T2, and T3 and T0 in the two groups (all P<0.05), and the HR and MAP decreased to a certain extent in the
two groups. The awakening time and leaving time of the study group were shorter
than those of the control group, and the incidence of respiratory depression
was lower than that of the control group [0 vs. 3.89% (7/180)], with
statistically significant differences (all P<0.05).
The Alderete scores of the study group 10, 20, and 30 min after operation were
higher than those of the control group, with statistically significant differences
(all P<0.05). The incidences of
postoperative pain [6.67 (3/180) vs. 38.33% (18/180)] and nightmare recall [0
vs. 16.67% (8/180)] in the study group were lower than those in the control
group, with statistically significant differences (both P<0.05). After operation, the Ramsay score and OAA/S wakefulness
score of the study group were higher than those of the control group, with
statistically significant differences (both P<0.05).
After operation, the NRS score of the study group was lower than that of the
control group [(1.03±0.27) vs. (2.46±0.34)], with a statistically significant
difference (t=44.189, P<0.001). Conclusion Dexmedetomidine can be used for daytime
hysteroscopy, which has good anesthetic effect, high safety, and less impact on
patients' vital signs, so it is worthy of application.
