Abstract

• The purpose of this study was to compare the effect of the Z-track intramuscular injection technique with the effect of the stand and intramuscular injection technique on the severity of discomfort and leasions at the injetion site. The subjects of the study were 20 patients with only early tuber culosis excluding another abnormalities (a skin rash, allergy to topical use of alcohol, jaundice, edema, neurosensory abnormality, coagulation defects, obesity and thin). Data collection was done from Feb. 1 to March 15, 1988 by means of Korean Pain Measurement Tool, Visual Analogue Scale, and Objective measures of injection site lesions. The results of this study were as follows;1) Hypothesis 1 ; "The severity of subject discomfort is less following administration of the Z-track intramuscular injection technique than following administration injection technique." was not sopported 2) Hypothesis 2 ; "The degress of severity subject discomfort is less following administration of the Z-track intramuscular injection technique than following administration of the standard intiamusc ular injection technique." was not supported. 3) Hypothesis 3 ; "The severity of injection site lesions is less following administra tion of the Z-track in-tramusc ular injection tech nique than following administra tion of the standard intramuscular injection techniques." was not supported. 4) The terms that were selected included factor II (mild-moderate pain) of Ratio Scale Measuring Pain using Korean Pain Terms. In conclusion; it was found that there was not a difference from the severity of subject discomfort between two groups, but the degress of severity of subject discomfort about following admini stration of the Z-track intramuscular injection was tended to be declined. Therefore further studies suggest that the Z-track in-tramu scular injection technique can decrease the severity of discomfort in persons receiving freauently intramuscular injections. First of all, it is necessery to be developed an effective tool of dis comfort measurement for the intramuscular injection in Korean.
