Abstract PDF: Critical care has focused on recovery from acute organ failure and resuscitation. Neuromuscular abnormalities related to critical illness is not uncommon in critically ill patients, but they were relatively underestimated and unnoticed. Intensive care unit acquired weakness (ICUAW) leading to severe functional impairments in ICU survivors can be divided into two disease entities: critical illness polyneuropathy (CIP) and critical illness myopathy (CIM). Electrophysiologic study, muscle biopsy and physical examination are helpful to diagnose ICUAW. Several researches and reviews identified many risk factors including systemic inflammation, corticosteroids, hyperglycemia, and immobility. Additional research is needed to identify the pathogenesis of this disorder and to testify its preventive or therapeutic modalities.

BACKGROUND
Although head of bed (HOB) elevation is an important strategy to prevent ventilator associated pneumonia (VAP), some observational studies have reported that the application of the semi-recumbent position was lower in patients receiving mechanical ventilator support. We performed this study to assess the effect of implementation of the HOB elevation protocol in the intensive care unit (ICU) on clinical and nutritional outcomes.
METHODS
We developed a HOB elevation protocol including a flow chart to determine whether the HOB of newly admitted patients to ICU could be elevated. We measured the level of HOB elevation in patients with mechanical ventilator twice a day and 2 days a week for 5 weeks before and after the implementation of the protocol, respectively. Hemodynamic, respiratory and nutritional data were also collected, resulting in 251 observations from 35 patients and 467 observations from 66 patients before and after implementation.
RESULTS
After implementing the protocol, the level of HOB elevation (16.7 +/- 9.9 vs. 23.6 +/-1 2.9, p < 0.0001) and observations of HOB elevation > 30degrees increased significantly (34 vs. 151, p < 0.0001). There was no significant difference in the incidence of VAP. Arterial oxygen tension/fraction of inspired oxygen ratio improved (229 +/- 115 vs. 262 +/- 129, p = 0.02). Mean arterial blood pressure decreased after the implementation of the protocol, but remained within the normal limits. Calorie intake from tube feeding increased significantly (672 +/- 649 vs. 798 +/- 670, p = 0.021) and the events of high gastric residual volume (> 100 ml) occurred less frequently after implementing the protocol (50% vs. 17%, p = 0.001) CONCLUSIONS: Implementation of the protocol for HOB elevation could improve the level of HOB elevation, oxygenation parameter and enteral nutrition delivery.

Abstract PDF: Introduction: Lung Injury Score (LIS) provides a quantitative method for scoring acute lung injury that usually occurs after sepsis. The aim of this study is to evaluate the LIS in prediction the patients outcome and determine the relationship between the LIS and mortality rate, acute physiology and chronic health evaluation II (APACHE II) score and multiple organ failure (MOF) score.
METHODS
Patients admitted to Intensive Care Unit (ICU), Severance Hospital Yonsei University College of Medicine from November 1995 to March 1996 were included. LIS at admission and discharge, APACHE II score with MOF score and duration of ICU stay between survivors and nonsurvivors were compared. Relationship of LIS between mortality rate and APACHE II score and MOF score were evaluated.
RESULTS
LIS is higher in nonsurvivors than survivors at admission and discharge with statistical significance. LIS of survivors and nonsurvivors at discharge was lower and higher than those at admission (p<0.05) respectively. Correlation coeffcient of LIS with mortality rate, MOF score and APACHE II score were 0.60 (p<0.05), 0.23 and 0.17.
CONCLUSIONS
LIS score was highly correlated with mortality rate. Therefore LIS is a good predictor of outcome in the intensive care unit.
