With the continuous development of medical technology,the clinical demand for medical consumables is steadily increasing.The management of medical consumables directly impacts both patient safety and institutional operational effi-ciency.By conducting in-depth analysis of the current status and existing problems in medical consumables warehouse manage-ment,this research proposes measures to improve the management system.These measures include optimizing the layout of ware-houses,improving the informatization of warehouse management,strengthening the inventory management of medical consuma-bles,enhancing the management of secondary warehouses,and offering professional skills training for warehouse staff.Manage-ment methods such as PDCA(Plan-Do-Check-Act)are used to continuously optimize warehouse management,enhance the man-agement efficiency of medical consumables management,and ultimately achieve refined management of medical consumables warehouses.

Objective To evaluate the accuracy of air column width difference (ACWD) between inflation and deflation of the cuff of the endotracheal tube (ETT) in predicting post-extubation stridor (PES).Methods A total of 102 intubated patients of both sexes and all ages,who were mechanically ventilated for ≥24 h in the intensive care unit,of American Society of Anesthesiologists physical status Ⅲ or Ⅳ,were enrolled in the study.After the patients were in a stable condition and recovered consciousness and myodynamia,they were weaned from the ventilator,and ultrasound examination of the larynx was performed to determine ACWD between ETT cuff inflation and deflation.PES was assessed using blinding nethod after extubation,and the patients were divided into 2 groups depending on whether or not the patients developed PES:PES group (group P) and non-PES group (group N).Results There were 94 patients in group N and 8 patients in group P.Compared with group N,ACWD was significantly decreased in group P (P＜ 0.05).The cut-off value of ACWD determined by the receiver operating characteristic curve was 1.65 mm,the sensitivity and specificity of ACWD were 0.830 and 0.750,respectively,and the area under the receiver operating characteristic curve was 0.801.Conclusion For the intubated patients who are mechanically ventilated for ≥24 h in an intensive care unit,ACWD between ETT cuff inflation and deflation＜ 1.65 mm can effectively predict PES.

[Objective] To research the sedative effect of intranasal dexmedetomidine and sufentanil for pediatric sedation for stomatological operation of outpatient department.[Methods] 60 children undergoing stomatological operation of outpatient department,age 3 ～ 7 years,weighing 10 ～ 32 kg,of ASA physical status Ⅰ ～ Ⅱ,were divided into the three groups (n =20) randomly using a random number table:group dexmedetomidine and sufentanil (group DS),group dexmetomidine (group D),group sufentanil (group S).Recorded the children's behavior using the Ohio State University behavior rating score (OSUBRS),the University of Michigan Sedation Score (UMSS),SBP,HR and side-effects when entry,during and leave operation and in post-anesthesia care unit,side-effects,the satisfaction of stomatological doctors and parents.[Results] The OSUBRS of group DS when entry,during operation were lower than group D (P ＜ 0.01).The UMSS of group DS were higher than group D and group S when entry and during operation (P ＜ 0.05).The success rate of group DS was higher than group D and group S (P ＜ 0.01).There was no different of mean percentage change in systolic blood pressure and heart rate from baseline between group DS and group D (P ＞ 0.05).There were no instances of respiratory depression,hypotension and bradycadia.[Conclusion] Intranasal dexmedetomidine and sufentanil provides satisfactory pediatric sedation for stomatological operation of outpatient department without side effects such as respiratory depression,bradycadia and hypotension.
