Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and ‎methicillin-resistant Staphylococcus aureus and Candida species). 

Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.

Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members. 

Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.

Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible.

Background: Optimal oxygen supply is the cornerstone of the management of critically ill patients after extubation, especially in patients at high risk for extubation failure. In recent years, high flow oxygen system devices have offered an appropriate alternative to standard oxygen therapy devices such as conventional face masks and nasal prongs.

Objectives: To assess the clinical effects of high flow nasal cannula (HFNC) compared with standard oxygen face masks in Intensive Care Unit (ICU) patients after extubation.

Methods: We retrospectively analyzed 67 consecutive ventilated critical care patients in the ICU over a period of 1 year. The patients were allocated to two treatment groups: HFNC (34 patients, group 1) and non-rebreathing oxygen face mask (NRB) (33 patients, group 2). Vital respiratory and hemodynamic parameters were assessed prior to extubation and 6 hours after extubation. The primary clinical outcomes measured were improvement in oxygenation, ventilation-free days, re-intubation, ICU length of stay, and mortality.

Results: The two groups demonstrated similar hemodynamic patterns before and after extubation. The respiratory rate was slightly elevated in both groups after extubation with no differences observed between groups. There were no statistically significant clinical differences in PaCO2. However, the use of HFNC resulted in improved PaO2/FiO2 post-extubation (P < 0.05). There were more ventilator-free days in the HFNC group (P < 0.05) and fewer patients required re-intubation (1 vs. 6). There were no differences in ICU length of stay or mortality.

Conclusion: This study demonstrated better oxygenation for patients treated with HFNC compared with NRB after extubation. HFNC may be more effective than standard oxygen supply devices for oxygenation in the post-extubation period.
