The Z-track intramuscular injection technique was compared with the standard injection technique for incidence and severity of discomfort and lesions at the injection site. Fifty subjects received injections of meperidine hydrochloride alone or in combination with promethazine hydrochloride every 3 to 4 hours for a total of two to eight injections. Subjects served as their own controls by receiving both techniques. They were evaluated for the presence and severity of discomfort on a 4-point Likert scale. Injection site lesions were determined by visualization and palpation. The Z-track technique significantly decreased incidence of selected descriptors of discomfort and lesions at selected time intervals, severity of discomfort at selected time intervals, and severity of lesions at all time intervals postinjection.
将Z形轨迹肌内注射技术与标准注射技术在注射部位不适和损伤的发生率及严重程度方面进行了比较。五十名受试者每3至4小时接受盐酸哌替啶单独注射或与盐酸异丙嗪联合注射，总共注射两至八次。受试者通过接受两种技术成为自身对照。根据4级李克特量表评估他们不适的存在及严重程度。通过观察和触诊确定注射部位损伤。Z形轨迹技术在选定时间间隔显著降低了选定不适描述和损伤的发生率、选定时间间隔的不适严重程度以及注射后所有时间间隔的损伤严重程度。
