Objective To investigate the current situation of healthcare-associated infection(HAI)management in secondary and above medical institutions in Shaanxi Province,analyze development trend,and put forward sugges-tions for improvement.Methods In May-June,2016,170 secondary and above hospitals in 10 cities were selected for surveying through stratified random sampling method.Survey content included basic situation of hospitals,HAI management,HAI monitoring,and so on.Results Available questionnaires were obtained from 165 hospitals (43 tertiary hospitals,and 122 secondary hospitals).Of 165 hospitals,more than 90% have established HAI manage-ment organizations and regulations,but hospital risk management should be paid more attention,only 63.03% of hospitals perfected the risk management system and 66.06% conducted risk assessment.99.09% of hospitals im-plement training on HAI to all staff regularly and 88.41% conducted effective feedback.In the aspect of staff alloca-tion,88.48% of the hospitals assigned enough professionals for HAI management,but only 34.55% have specific training programme for these personnel.Only 33.94% of hospitals have special funds for HAI control;in the aspect of monitoring on HAI,21.21% of hospital installed and used HAI monitoring software;In the aspect of implemen-tation of monitoring programme,about 90% of hospitals developed monitoring on HAI cases and environmental hy-giene,but only 34.55% and 23.64% of hospitals conducted targeted monitoring on intensive care unit and neonatal intensive care unit respectively.Conclusion Organizational structure of HAI management in Shaanxi Province is perfect,relevant rules and regulations are basically established,basic monitoring projects are universal,but the awareness of risk management needs to be strengthened,professional allocation and professional quality develop-ment are both imbalance,informational monitoring is inadequate.

Objective:To evaluate the changes in the systemic circulation and microcirculation in the patients undergoing gastrointestinal surgery under general anesthesia in Xining area.Methods:A total of 27 patients, aged 18-60 yr, underwent gastrointestinal surgery under general anesthesia in Xining area (2 260 m), of long lived (more than two generations) Han nationality, with no alternating life between plateau and plain, with no cardiopulmonary abnormalities, were enrolled.Anesthesia was induced with midazolam, sufentanil, etomidate, and cisatracurium and maintained with propofol, remifentanil and cisatracurium.At 5 min before induction of anesthesia (T 1), 10 min after induction of anesthesia (T 2), 1 h after start of operation (T 3), immediately after the end of operation (T 4), and 30 min after recovery from anesthesia (T 5), systemic circulation indexes including cardiac output (CO), stroke volume (SV), stroke volume variability (SVV), systemic vascular resistance index (SVRI), and mean arterial pressure (MAP) and heart rate (HR) were recorded, and sublingual microcirculation indexes including total vascular density (TVD), perfused vessel density (PVD), portion of perfused vessels (PPV), and microvascular flow index (MFI) were determined by sidestream dark field imaging. Results:Systemic circulation Compared with the baseline at T 1, CO and HR were significantly decreased at T 2-4, SVV was decreased at T 5, SVRI was increased at T 3 and T 4, and MAP was decreased at T 2 ( P<0.05). Compared with those at T 2, CO and SV were significantly increased at T 5, SVV was decreased at T 5, SVRI was increased at T 3 and T 4, and MAP was increased at T 4 and T 5 ( P<0.05). Compared with those at T 3, SV was significantly decreased at T 4, CO was increased at T 5, and SVV and SVRI were decreased at T 5 ( P<0.05); Compared with those at T 4, CO, SV and HR were significantly increased at T 5, and SVV and SVRI were decreased at T 5 ( P<0.05). Microcirculation Compared with those at T 1, TVD, PVD, PPV and MFI were significantly decreased at T 2-4, and PPV and MFI were decreased at T 5 ( P<0.05). Compared with those at T 2, TVD was significantly increased at T 5, PVD was increased at T 4 and T 5, and PPV was increased at T 3 and T 4 ( P<0.05). TVD was significantly higher at T 5 than at T 3( P<0.05). TVD was significantly higher at T 5 than at T 4 ( P<0.05). Conclusions:The density of microcirculation and blood flow rate are decreased after induction of general anesthesia and during anesthesia operation, which are most significant at the initial stage after induction, and decoupling between systemic circulation and microcirculation occurs during operation and anesthesia resuscitation in the patients at high altitude.
