Abstract:
Objective To assess the application value of disposable syringe of low resistance (SLR) in epidural puncture.Methods One hundred and thirty-two patients scheduled to undergoing selective operation under epidural or combined epidural-spinal anesthesia were divided into glass syringe (GS) group and SLR group with 66 cases each by random digits table method.GS was applied in local anesthesia and epidural puncture with loss of resistance in GS group.While SLR was used in SLR group.The defect of the syringes' appearance was evaluated.The fastness between each sub-unit during the procedure was observed.The rupture,dropping,leakage,air leakage and blockage were also estimated.The heart rate,blood pressure,oxygen saturation and other adverse events were also observed.Results In SLR group,syringe excepted 1 case of slight resistance but did not affect the use,the rest of the components connected firmly,surface without defects,clear scale uniform color,not observed rupture,air leakage,leakage and blockage phenomenon,pump liquid and air resistance was small.In GS group,syringe surface without defects,clear scale uniform color,3 cases had loose connection,1 case with rupture when using,5 cases with air leakage and leakage,3 cases of pumping liquid or dry air resistance to 0.9％ sodium chloride and moist after use.There was significant difference in appearance and usage between two groups (x2 =10.324 5,P =0.001 3).There was no significant difference in a puncture success,first three puncture success and inject air negative pressure sensitivity between two groups (P ＞ 0.05).Conclusion SLR is worth to be applied in epidural puncture.
