Bronchial Responsiveness in Children Exposed to Atmospheric Pollution in Hong Kong: Histamine Challenge Test
Consent for use of histamine challenge tests was obtained after submission of a proposal to the institution’s ethics committee. The children received a bronchial challenge by histamine according to the method of Yan et al. Those children who had experienced an upper respiratory tract infection in the past 10 days with symptoms on the day […]
Bronchial Responsiveness in Children Exposed to Atmospheric Pollution in Hong Kong: Subjects
During the period January 1989 to December 1990, maximum daily levels of one or more of the following pollutants, sulfur dioxide (S02), nitrogen dioxide (N02), total suspended particulates (TSP), respirable suspended particulates (RSP), and ozone (O3), exceeded World Health Organization recommended standards on four occasions in KDT. No excess levels were reported for SDT. Eleven […]
Bronchial Responsiveness in Children Exposed to Atmospheric Pollution in Hong Kong
There is strong evidence of an association between atmospheric pollution, especially that produced by oxides of sulphur and nitrogen, ozone, and suspended particulates, and respiratory symptoms in exposed populations. There is concern that children exposed to these pollutants might be adversely affected in terms of their growth potential or predisposed to respiratory diseases during childhood […]
Unplanned Extubation: Appendix
Our data suggest that patients receiving an FI02 >0.40 are at high risk for respiratory failure after unplanned extubation, while those receiving an FI02 <0.40 can be safely observed after such an event. Total ventilatory support before to unplanned extubation, estimated by We, was also significantly higher in the RI group other generic allegra. This […]
Unplanned Extubation: Conclusion
Reintubation after unplanned extubation should not be considered mandatory. Our reintubation incidence of only 78 percent (18 of 23 events) supports this position, and other series have reported reintubation rates as low as 31 percent.2 Furthermore, one group noted that 90 percent of the self-extubated patients in their study could have had more timely weaning […]
Unplanned Extubation: Discussion
Unplanned extubation—self-extubation or accidental extubation—occurs with surprising frequency in mechanically ventilated patients. In our study, the incidence of unplanned extubation was 7 percent, similar to the 8.5 percent to 16 percent reported in other studies. Furthermore, unplanned extubation is difficult to prevent, as evidenced by the fact that 65 percent of our patients had been […]
Unplanned Extubation: Results
During the study period, there were 319 mechanically ventilated patients in the MICU; 23 unplanned extubations occurred during the same period (7 percent of all ventilated patients). Of the 23 events, only 2 appeared to have been accidental extubations, while the remainder were most likely intentional (self-extubations). In all cases, important measures had been taken […]
