目的 了解综合重症监护病房（ICU）呼吸机相关性肺炎（VAP）感染率、危险因素、病原菌分布及其耐药情况，探讨有针对性的预防控制措施。 方法 2009年1月－12月综合ICU共收治患者447例，采用主动监测方法，由ICU医务人员和专职人员每日对综合ICU病房住院时间≥48 h且撤停机械通气后48 h内的患者进行VAP监测。 结果 447例患者中住院时间≥48 h的患者168例，96例患者使用呼吸机，使用呼吸机时间182 d，ICU住院总日数1 339 d，发生VAP 17例，呼吸机使用率13.59%，VAP感染率93.4例/1 000机械通气日，根据平均病情严重程度（ASIS法）调整后的VAP感染率为2.38%。呼吸机使用方式与VAP发生有关联。检出病原菌18株，全部为Gˉ杆菌，其中鲍曼不动杆菌4株，对包括硫霉素、氨曲南在内的多种抗菌药物耐药。 结论 综合ICU病房VAP感染率为2.38%，呼吸机使用不当是VAP的危险因素，VAP致病菌为Gˉ杆菌，其中鲍曼不动杆菌耐药率达100%，并呈多重耐药性；抗生素使用时间过长，预防性使用不当是致病菌产生多重耐药的重要原因。
ObjectiveTo investigate the application value of noninvasive ventilation (NIV) performed in patients with unplanned extubation (UE) in intensive care unit (ICU).MethodsThis was a retrospective analysis. The clinical data, application of NIV, reintubation rate and prognosis of UE patients in the ICU of this hospital from January 2014 to December 2018 were reviewed, and the patients were assigned to the control group or the NIV group according to the application of NIV after UE. The data between the two groups were compared and the application effects of NIV in UE patients were evaluated.ResultsA total of 66 UE patients were enrolled in this study, including 44 males and 22 females and with an average age of (64.2±16.1) years. Out of them, 41 patients (62.1%) used nasal catheter or mask for oxygenation as the control group, 25 patients (37.9%) used NIV as the NIV group. The Acute Physiology andChronic Health EvaluationⅡ score of the control group and the NIV group were (18.6±7.7) vs. (14.8±6.3), P=0.043. The causes of respiratory failure in the control group and the NIV group were as follows: pneumonia 16 patients (39.0%) vs. 7 patients (28.0%), postoperative respiratory failure 7 patients (17.1%) vs. 8 patients (32.0%), chronic obstructive pulmonary disease 8 patients (19.5%) vs. 6 patients (24.0%), others 5 patients (12.2%) vs. 4 patients (16.0%), heart failure 3 patients (7.3%) vs. 0 patients (0%), nervous system diseases 2 (4.9%) vs. 0 patients (0%), which showed no significant difference between the two groups. Mechanical ventilation time before UE were (12.5±19.8) vs (12.7±15.2) d (P=0.966), PaO2 of the control group and the NIV group before UE was (114.9±37.4) vs. (114.4±46.3)mm Hg (P=0.964), and oxygenation index was (267.1±82.0) vs. (257.4±80.0)mm Hg (P=0.614). Reintubation rate was 65.9% in the control group and 24.0% in the NIV group (P=0.001). The duration of mechanical ventilation was (23.9±26.0) vs. (21.8±26.0)d (P=0.754), the length of stay in ICU was (34.4±36.6) vs. (28.5±25.8)d (P=0.48). The total mortality rate in this study was 19.7%. The mortality rate in the control group and NIV group were 22.0% and 16.0% (P=0.555).ConclusionPatients with UE in ICU may consider using NIV to avoid reintubation.
Ambulatory surgery ward is a fast and effective way of treating, nursing and patients’ education. We report the practice of ambulatory surgery ward in West China Hospital of Sichuan University about patients’ reception, treatment and nursing, medical safety, health education and post-operative follow-up. Results show that ambulatory surgery ward would guarantee patients’ safety, shorten hospitalization days and decrease medical cost, with more than 98% of patients’ satisfaction.
ObjectiveTo observe the effect of bundle interventions on ventilator-associated pneumonia (VAP) in Intensive Care Unit (ICU). MethodsBaseline survey among the patients undergoing mechanical ventilation was conducted during June 2011 to August 2011. During September 2011 to May 2012, the rate of VAP was monitored every three months after taking bundle measures, which included oral care, elevation of the head of the bed, daily assessment of readiness to extubation, optimizing process of devices disinfection and hand hygiene. ResultsThrough carrying out the bundle interventions, the VAP rate decreased from 61.2‰ to 34.9‰ after six months and 22.7‰ after nine months, and the ventilator utilization ratio decreased from 26.5% to 24.6% after six months and 22.6% after nine months. The alcohol-based hand disinfectant dosage was increased from 32.6 mL to 58.8 mL and 54.4 mL for each patient bed in ICU. ConclusionThe bundle intervention has been proved to be effective. Measures such as staff education, bedside supervision and monitoring data feedback can help implement bundle interventions.
The concept of "enhanced recovery after surgery (ERAS)" has been well known by care providers. Implementation of the ERAS principles requires minimally invasive surgical technology in conjunction with multidisciplinary teamwork. Only if these two aspects of peri-operative care regime optimization and "all-in-one model in medical" care were linked up associatelly, ERAS could be realized. Thoracoscopic surgery was a milestone in thoracic surgery. The successful application of such a recovery program requires the foundation of pain and risk free ward in perioperative period and improving quality of life post discharge. This review summarizes the peri-operative regimen care optimization regarding the utility of ERAS in the VATS lobectomy of patients with lung cancer. The first one is preoperative evaluation issues. It involves conditioning the patient and implementing a pre-operative exercise and a physical therapy regimen. The second one is operative and individual anesthetic maneuvers and the selective use of tube in the post-operative period. The third one is the foundation of pain and risk free ward:what are methods optimum of post operative management? The fourth one is medical management of patient's outcomes and the ERAS regimen continuing optimum. The fifth one is the importance of function of multi-departmental coordination in ERAS.
Objective To investigate the effect of quality control circle in reducing ventilator-associated pneumonia in Pediatric Intensive Care Unit (PICU). Methods A total of 1 249 child patients who underwent mechanical ventilation between January and December 2013 were chosen as the control group, and they accepted routine management. Another 1 208 child patients treated between January and December 2014 were selected as the observation group, and quality control circle was adopted. The compliance of ventilator care bundles, the duration of mechanical ventilation, the length of PICU stay and the incidence of ventilator-associated pneumonia were compared between the two groups. Results Compared with the control group, compliance of ventilator care bundles was higher in the observation group (P<0.01), the duration of mechanical ventilation was shorter [(6.9±2.4) daysvs. (4.6±2.2) days], the length of PICU stay was shorter [(9.2±3.1) daysvs. (7.7±2.4) days], and the incidence of ventilator-associated pneumonia was lower (22.4‰vs. 9.1‰) (P<0.05). Conclusion Application of quality control circle can significantly promote the compliance of ventilator care bundles, and decrease the duration of mechanical ventilation, the length of PICU stay and the incidence of ventilator-associated pneumonia.
Objective To investigate the drug resistance and homogeneous analysis of Acinetobacter baumanii in emergency intensive care unit ( EICU) . Methods Four multidrug-resistant Acinetobacter baumannii ( MDR-Ab) strains isolated fromnosocomial inpatients fromJuly 25 to September 7 in 2009 were collected and tested for drug sensitivity and MIC determination as well. The A. baumannii isolates were typed with pulsed-field gel electrophoresis ( PFGE) to determine whether they derived fromthe same clone.Results Four isolates from nosocomial inpatients were resistant to multiple antibiotics including carbapenem. The PFGE types identified from four isolates were A and B. The A. baumannii isolates did not derived from the same clone. Conclusion The prevalence of nosocomial infection is not due to transmission of the same strains among different individuals in EICU.
