不同型号传统银质针温针灸在人体内的温度特性比较

目的在艾球加热条件下,观察长180 mm、160 mm两种型号传统银质针在人体内的温度特性差异。方法将72例受试者随机分为A组(1.1 mm×180 mm单针组)、B组(1.1 mm×160 mm单针组)、C组(1.1 mm×180 mm多针组)和D组(1.1 mm×160 mm多针组),每组18例。4组受试者均在臀部测温点(左臀部内上方,髂嵴上缘最高点下7 cm,后正中线旁开7 cm)分别刺入测温银质针,C组和D组在臀部进针点上、下、左、右4个配针点(距测温点2 cm)再刺入4根与测温银质针等长的银质针,针尾均装有1.3 g艾球,点燃艾球后用数字测温仪自动动态记录测温银质针针尖上方3 mm、33 mm、63 mm、66 mm处银质针的温度。结果 A组测温银质针针尖上方3 mm、33 mm、63 mm、66 mm的最高温度与B组和C组比较,差异均具有统计学意义(P0.01,P0.05)。C组测温银质针针尖上方3 mm、33 mm、63 mm、66 mm的最高温度与D组比较,差异均具有统计学意义(P0.05)。B组测温银质针针尖上方3 mm、33 mm、63 mm、66 mm的最高温度与D组比较,差异均无统计学意义(P0.05)。结论两种规格银质针温针灸的针尖针身最高温度在单针针刺时均达41℃以上,多针针刺时均达43℃以上;在加热源及进针深度相同的条件下,人体内银质针的最高温度受银质针长短及针刺方式的影响,银质针越短,其最高温度越高,多针针刺的最高温度高于单针针刺方式。

Comparison of the Temperature Properties of Warm Needling Moxibustion with Traditional Silver Needles of Different Sizes in Human Body

Objective To compare the temperature properties ofmoxa ball-heeated traditional silver needles 18 cm and 16 cm long in human body. Methods Seventy-two subjects were randomly allocated to group A （single needle of 1.1 x180 mm）, group B （single needle of 1.1x160 mm）, group C （several needles of 1.1x180 mm） and group D （several needles of 1.1x180 mm）, 18 cases each. In all four groups of subjects, a temperature measuring silver needle was inserted into a temperature measuring point in the medial superior part of the left buttock （7 cm below the highest point of the iliac crest and 7 cm lateral to posterior median line）. In groups C and D, four silver needles as long as the temperature measuring silver needle, on each of whose tails a 1.3 g moxa ball was put, were inserted into four matching points 2 cm superior, inferior, left and right to the temperature measuring point in the buttock. After the moxa ball was ignited, the needle temperature at 3, 33, 63 and 66 mm above the tip of the temperature measuring silver needle was measured automatically and dynamically using a digit thermoscope. Results There were statistically significant differences in the highest temperatures at 3, 33, 63 and 66 mm above the tip of the temperature measuring silver needle between group A and group B or C （P〈0.01,P〈0.05） and between groups C and D （P〈0.05）. There were no statistically significant differences in the highest temperatures at 3, 33, 63 and 66 mm above the tip of the temperature measuring silver needle between groups B and D （P〉0.05）. Conclusions The highest temperatures of the needle tips and bodies in warm needling moxibustion with two sizes of silver needles reach over 41℃ in single needle placement and over 43 ℃ in several needles placement. Under the same heating source and needle insertion depth, the highest temperature of a silver needle in human body is influenced by silver needle length and the needling mode. The shorter the silver needle, the higher the maximum temperature. The maximum temperature is higher in several needles placement than in single needle placement.
