Effect of different puncture sites of vein indwelling trocar for infants with congenital heart disease

Abstract

Objective To compare successful rates among 3 different puncture sites of vein indwelling trocar for infants with congenital heart disease,and analyze failure reasons.Methods A total of 327 infants with congenital heart disease were randomly divided into 3 groups:the superficial temporal vein group with 106 cases,the dorsal hand vein group with 120 cases and the great saphenous vein group with 101 cases.The successful rates and influencing factors of these three groups were observed and analyzed.Results The successful puncture rate of superficial temporal vein group (92.45％) was higher than the dorsal hand vein group (80.83％) and the great saphenous vein group (80.20％),and the differences were statistically significant (x2 =6.151 8,6.371 5,respectively; P ＜ 0.05).The difference of successful rate between the dorsal hand vein group and great saphenous vein group was not statistically significant (P ＞ 0.05).The differences of failure rates among three groups due to infants' struggle,over-quick withdrawal,quality of indwelling needles and etc were all not statistically significant (P ＞ 0.05).The failure rate in the superficial temporal vein group due to non turgor vitalis was 0.00％,obviously lower than that in the dorsal hand vein group (7.50％) and the great saphenous vein group(5.94％),and the differences were statistically significant (x2 =8.7048,6.985 2,respectively; P ＜ 0.01).There was no significant difference of failure rates due to non turgor vitalis between the dorsal hand vein group and the great saphenous vein group (P ＞ 0.05).Conclusions Superficial temporal vein should be considered as the first choice for infants with congenital heart disease who need vein indwelling trocar puncture,so as to improve the successful puncture rate.
