摘要:
目的 探讨吸痰时咳嗽强度对气囊压力不达标的预测价值,旨在为个性化校正气囊压力提供参考。方法 2020年6月至2021年2月,便利选取某院50例建立人工气道的患者,采用半定量咳嗽强度评分法(semi-quantitative cough strength score,SCSS)评估吸痰时咳嗽强度,分析咳嗽强度与气囊压力不达标的相关性,绘制受试者工作特征(receiver operating characteristic,ROC)曲线,计算预测气囊压力不达标的咳嗽强度临界值。结果 SCSS 5分组吸痰时(最大值)的气囊压力为(88.67±8.04)cmH2O(1 cmH2O=0.098 kPa)。SCSS 4～5分组吸痰后20 min时气囊压力均低于正常范围,5分组平均损失8.50 cmH2O,不达标率为92.68%。吸痰时咳嗽强度对气囊压力的影响存在组别、时间和交互效应(P<0.001)。吸痰时咳嗽强度与气囊压力不达标呈中度正相关(r=0.563,P<0.001),ROC曲线下面积为0.820(P<0.001),最佳界值3.5,灵敏度0.716,特异度0.847。结论 吸痰时咳嗽强度对气囊压力不达标具有良好的预测价值,当SCSS评分≥4分时,建议吸痰后10 min重新校正气囊压力。
Abstract:
Objective To evaluate the predictive value of cough strength during suction on substandard cuff pressure, and to provide references for targeted adjustment of cuff pressure.Methods From June 2020 to February 2021, 50 patients who had been established an artificial airway in a hospital were selected as study subjects by convenience sampling method.The semi-quantitative cough strength score(SCSS)was used to evaluate the cough strength during sputum suction.The correlation between cough strength during suction and substandard cuff pressure was analyzed, and the receiver operating characteristic(ROC)curve was drawn to calculate the critical value of cough strength for substandard cuff pressure.Results The maximum cuff pressure value during sputum suction in the group with SCSS of 5 was(88.67±8.04)cmH2O.In the group with SCSS of 4-5, the cuff pressure values were lower than the normal range.The cuff pressure loss in the group with SCSS of 5 was 8.50 cmH2O, and the substandard rate was 92.68%.The cough strength during sputum suction influenced the cuff pressure in terms of group, time and interaction differences(all P<0.001).The cough strength during suction was positively correlated with the substandard cuff pressure(r=0.563, P<0.001).The area under ROC curve was 0.820(P<0.001), with a cutoff value of 3.5, sensitivity and specificity values of 0.716 and 0.847, respectively.Conclusions The cough strength during sputum suction has a good predictive value for the substandard cuff pressure.When the SCSS is greater than or equal to 4, it is recommended to recalibrate the cuff pressure at 10 min after suction.
