RESUMEN
Objective To study the application value of 5S management for the instrument management in ENT department.Methods Totally 20 instrument nurses in ENT department implementing 5S management were enrolled into an observation group,and another 20 nurses using conventional management method were involved in a control group.The two groups were compared on instrument management quality and instrument nursing management satisfaction.Results The observation group had the qualification rate of sampled sterile items,qualification rate of instrument packaging,qualification rate of instrument cleaning,efficiency of instrument application,instrument preparedness,standardized instrument allocation,intact rate of prepared instrument as well as the familiarity with instrument management and operation significantly better than those in the control group (P＜0.05).The time consumed for adding instrument,finding instrument,environment arrangement and finding expired goods in the observation group was statistically shorter than that in the control group (P＜0.05).The times of instrument set repeated disinfection in the observation group was obviously less than those in the control group (P＜0.05),and the satisfaction over nursing management in the observation group was also significantly better than that in the control group (P＜0.05).Conclusion 5S management gains high application values for instrument management in ENT department,and thus is worthy promoting clinically.
RESUMEN
OBJECTIVE@#To observe waveform difference among cervical vestibular evoked myogenic potentials (cVEMP) elicited with different types of air conducted sound in normal young Chinese subjects.@*METHOD@#Twenty adult volunteers (40 ears) were recruited as research subjects including 10 males and 10 females aged between 19 and 30.500 Hz Tone Burst, 1000 Hz Tone Burst and Click were employed as stimulus for conventional air conducted sound-cVEMP (ACS-cVEMP) examinations in bilateral ears of each subject. The response rate, threshold, P1 latency, N1 latency, P1-N1 latency interval, amplitude and inter-aural asymmetry were recorded and compared among groups.@*RESULT@#The response rate was 97.5% in 500Hz Tone Burst (39/40), 87.5% in 1 000Hz Tone Burst (35/40)and 67.5% in Click (27/40), There were no statistically significant difference between 500Hz Tone Burst and 1000Hz Tone Burst (P > 0.05) but there were statistically significant difference between click and the other groups (P < 0.05). We collected the waveform parameters (the threshold, P1 latency, N1 latency, P1-N1 latency interval, amplitude) which had statistically significant difference between 500 Hz Tone Burst and the other groups (P < 0.05). The inter-aural asymmetrys had no statistically significant differents among groups.@*CONCLUSION@#The response rate and parameter could be affected by different types of air conducted sound in normal young Chinese subjects. 500 Hz Tone Burst was the best stimulus of type what we have known.
