Abstract:
Objective To observe and compare the incidence rate of hemolysis while venous blood specimen collecting with two types of venous indwelling needle. To summarize the attentions during blood samples collecting by venous indwelling needle. Methods From January 2014 to January 2015, a total of 400 patients in resuscitation room of emergency department were divided into control group and experimental group by random digits table method with 200 cases each. Type Y indwelling needle was used in control group, while straight type indwelling needle was used in experimental group. Both two types of indwelling needle were required to be connected with the disposable venous blood taking needle joint for blood sample collection. The incidence rate of hemolysis was observed. Results The incidence rate of hemolysis in experimental group was lower than that in control group: 8.0%(16/200) vs. 39.5%(79/200),and there was significant difference, χ2=34.317, P < 0.01. Conclusions The incidence rate of hemolysis during venous blood specimen collecting with straight type indwelling needle is significantly lower than that with Y type indwelling needle. Straight type indwelling needle is worthy of clinical use.
