Objective To explore the clinical characteristics and treatment of paroxysmal supraventricular tachycardia (PSVT) in children. Methods The clinical data of 67 children with PSVT were analyzed retrospectively, and the therapeutic effects of different treatments were compared. Results The clinical manifestations of infants were paleness, shortness of breath, irritability and sweating, and children showed chest tightness, palpitations, abdominal discomfort and fatigue. The curative effect of electric cardioversion, transesophageal atrial pacing, physical therapy, and drug therapy was statistically different (P<0.05), The different cardioversion rates of them were observed for the treatment of paroxysmal supraventricular tachycardia. The cardioversion rate of transesophageal atrial pacing, was the highest, and the rate of physical therapy was the lowest. There was no significant difference in the cardioversion rate between propafenone, digoxin and amiodarone. Conclusion The clinical manifestations of PSVT in infants are atypical and easily to be ignored. There are many methods for treatment of PSVT. The vagus nerve can be stimulated first, and, if no response, either drugs or electric cardioversion and transesophageal atrial pacing can be used. The cardioversion rate of transesophageal atrial pacing is higher. The drug effectiveness for the treatment of PSVT depends on many factors, and our choice of medication varies from person to person.

OBJECTIVE:To systematically evaluate therapeutic efficacy of local application of gentamicin collagen sponge in the prevention of surgical incision infection,and to provide evidenced-reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,Cochrane Library,CBM,CJFD,VIP and Wanfang databases,randomized controlled trials (RCTs) about lo-cal application of gentamicin collagen sponge(trial group)vs. routine surgery disposal(control group)in the prevention of surgical incision infection were collected. After data extraction and quality evaluation with modified Jadad scale,Meta-analysis was per-formed by using Rev Man 5.3 statistical software. RESULTS:A total of 16 literatures were included,involving 7752 patients. The results of Meta-analysis showed that the incidence of surgical incision infection in trial group was significantly lower than control group,with statistical significance [OR=0.71,95%CI(0.61,0.84),P<0.001]. The packet statistics showed that the incidence of surgical incision infection in cardiovascular surgery group [OR=0.59,95%CI(0.37,0.96),P=0.03] and skin soft tissue operation group [OR=0.34,95%CI(0.15,0.75),P=0.008] were significantly lower than control group. There was no statistical significance in the incidence of incision infection between digestive system operation group and control group [OR=0.62,95%CI(0.25,1.54), P=0.30]. The incidence of surgical incision infection in≤30 d group was significantly lower than control group[OR=0.58,95%CI (0.41,0.82),P=0.002];there was no statistical significance between more than 30 d group and control group [OR=0.86,95%CI (0.71,1.04),P=0.13]. The incidence of surgical incision infection [OR=0.65,95%CI(0.52,0.82),P<0.001] in gentamicin high-dose group (>100 mg) was significantly lower than control group;there was no statistical significance between gentamicin low-dose group (≤100 mg) and control group [OR=0.96,95%CI(0.72,1.28),P=0.77]. CONCLUSIONS:Local application of gentamicin collagen sponge may have certain effect on the prevention of surgical infection. Different types of surgery,observation time and dose have different prevention effects. It should be used carefully according to clinical practice.
