Chinese Journal of Digestive Endoscopy 2017;34(2):112-117
Objective To explore the clinical effect of intranasal dexmedetomidine as premedication on sedation and analgesia during painless electronic colonoscopy in children, and to investigate its optimal dose. Methods Ninety children scheduled for painless electronic colonoscopy were divided into three groups by using a computer?generated randomization schedule, 30 per group. Children were pretreated with 0. 2 mg/kg midazolam ( group A) , 1. 0μg/kg dexmedetomidine ( group B) or 2. 0μg/kg dexmedetomidine ( group C) by nasal drip 30 min before operation. The anesthesia protocol was programmed by propofol in the three groups. After eyelash reflex disappeared, the examination was performed. Mean artery blood pressure ( MAP ) , heart rate (HR), respiratory rate (RR) and oxygen saturation (SPO2) of children were recorded at 10 min before intranasal administration ( T0 ) , 30 min after intranasal administration ( T1 ) , at the onset of eyelash reflex disappearance ( T2 ) and the onset of examination initiating( T3 ) , at lens passing through splenic flexure ( T4 ) , or through hepatic flexure ( T5 ) , at the end of examination ( T6 ) and when patients were fully awake ( T7 ) , respectively. Bispectral index ( BIS) and the observer's assessment of alertness/sedation scale ( OAA/S) were performed at 10 min before intranasal administration ( T0 ) , 10 min, 20 min and 30 min after intranasal administration in the three groups. Mood score at parent?children separation and venipuncture acceptance score were also recorded. The adverse reactions during examination were analyzed. The above observed indices were compared among the three groups. If there was statistical difference ( P<0. 05 ) , pairwise comparison was performed ( P<0. 017) . Results The children's haemodynamics were all stable in the three groups. Compared with group A and group B at the same time point, BIS and OAA/S were all lower ( P<0. 017) in 10 to 30 min after intranasal administration in group C. Compared with group A and group B, mood score at parent?children separation and venipuncture acceptance score were both higher ( P<0. 017) in group C. Compared with group A and B, anesthetic revival time and consumption of propofol were shorter or lower in group C (P<0. 017). Compared with group A and group B, the incidences of intraoperative adverse reactions including hypertension, sinus tachycardia, restless moving and postoperative restlessness were all lower in group C(P<0. 017). The rate of intranasal stimulus in group B and group C were both lower than that of group A( P<0. 017) . The rate of injection pain of group C was lower ( P<0. 017 ) than that of group A and B. Conclusion Intranasal administration of dexmedetomidine can be safely applied to children receiving painless electronic colonoscopy, and it can improve children's compliance effectively and yield to satisfactory anesthetic effect. Moreover, the administering efficacy of dexmedetomidine with the dose of 2. 0μg/kg was superior to 1. 0μg/kg.

Objective To evaluate the curative effect of Keli-Paoxi power for the treatment of acute paronychia. Methods A total of 144 patients with acute paronychia were randomly divided into a Keli-Paoxi power group, a mupirocin ointment group and an ethanol soaking group, 48 in each group. All patients were treated for 3 weeks and followed-up for 2 months. The time to regression of redness and swelling in the nail groove was recorded. The Visual Analogue Scale (VAS) was used to assess tenderness. The curative effects were evaluated, and recurrence of paronychia was recorded. Results The time to regression of redness and swelling in the nail groove in the Keli-Paoxi power group (2.2 ± 0.6 d) was significantly shorter than that in the mupirocin ointment group (8.1 ± 1.7 d) or ethanol soaking group (7.9 ± 1.2 d; F=344.597, P<0.01). The VAS Scores in the Keli-Paoxi power group (1.2 ± 0.2) was significantly lower than that in the mupirocin ointment group (3.2 ± 0.3) or ethanol soaking group (3.1 ± 0.3; F=831.273, P<0.01). The total effective rate in the Keli-Paoxi power group (100.0%, 48/48) was significantly higher than that in the mupirocin ointment group (83.3%, 40/48) or ethanol soaking group (81.3%, 39/48; χ2=9.700, P=0.008). The recurrence rate of paronychia in the Keli-Paoxi power group (2.1%, 1/48) was significantly lower than that in the mupirocin ointment group (16.7%, 8/48) or ethanol soaking group (14.6%, 7/48; χ2=6.000, P=0.049) at 2 months follow-up. Conclusions Keli-Paoxi power can alleviate tenderness, shorten the time to regression of redness and swelling in the nail groove, decraese recurrence in patients with acute paronychia. The curative effect of Keli-Paoxi power is superior to mupirocin ointment and ethanol soaking in the treatment of acute paronychia.
