Activities of daily living status and psychiatric symptoms after discharge from an intensive care unit: a single-center 12-month longitudinal prospective study.

AIM: In post-intensive care syndrome (PICS), long-term survivors of critical illness present various physical and mental symptoms that can persist for years after discharge. Post-intensive care syndrome in Japan has not been well described, so this study aims to elucidate its epidemiology. METHODS: We undertook a single-center prospective longitudinal cohort study in a mixed intensive care unit (ICU) in a Japanese tertiary hospital. Adult patients emergently admitted to the ICU were eligible for inclusion in the study. To assess activity of daily living (ADL) status and psychiatric symptoms, we posted a questionnaire at 3 and 12 months after discharge from the ICU. We evaluated ADL status, anxiety, depression, and post-traumatic stress disorder symptoms using the Barthel index, Hospital Anxiety and Depression Scale, and Impact of Event Scale - Revised, respectively. RESULTS: Enrolled in this study were 204 patients. We received responses from 117/147 (80%) and 74/98 (76%) patients at 3 and 12 months, respectively. At 3 months, the prevalence of ADL disability, anxiety, depression, and post-traumatic stress disorder symptoms was 32%, 42%, 48%, and 20%, respectively. At 12 months, the prevalence was 22%, 33%, 39%, and 21%, respectively. The prevalence of any symptoms was 66% at 3 months and 55% at 12 months. Barthel index score at 12 months was improved significantly from that at 3 months. Hospital Anxiety and Depression Scale and Impact of Event Scale - Revised scores at 12 months showed no improvement. CONCLUSIONS: At 3 and 12 months after ICU discharge, over half of our Japanese patients suffered ADL disability and/or psychiatric symptoms. The ADL disability improved at 1 year, but psychiatric symptoms did not.

Evaluation of transcatheter arterial embolization with gelatin sponge particles, microcoils, and n-butyl cyanoacrylate for acute arterial bleeding in a coagulopathic condition.

PURPOSE: To evaluate the outcome of transcatheter arterial embolization with gelatin sponge particles, microcoils, and N-butyl cyanoacrylate (NBCA) for acute arterial hemorrhage in the setting of coagulopathy. MATERIALS AND METHODS: Coagulopathy is defined by a platelet count less than 5 x 10(4)/microL and/or International Normalized Ratio (INR) greater than 1.5. Forty-six patients (31 male patients; mean age, 62 years) with acute arterial hemorrhage in a coagulopathic condition were treated by transcatheter arterial embolization with gelatin sponge particle, microcoils, and NBCA. RESULTS: Because of failure of hemostasis or recurrent hemorrhage, 10 patients who underwent gelatin sponge particle embolization also received transcatheter arterial embolization with microcoils or NBCA embolization and two patients who underwent microcoil embolization also received transcatheter arterial embolization with NBCA. The gelatin sponge particle group consisted of 27 hemorrhagic arteries in 25 patients, the microcoil group had 20 in 20 patients, and the NBCA group had 16 in 13 patients. The mean platelet count and mean INR value were 5.8 x 10(4)/microL +/- 3.5 and 1.81 +/- 0.50, respectively. The primary hemostatic rate, recurrent hemorrhage rate, and mean treatment time for the gelatin sponge particle, microcoil, and NBCA groups were 67%, 23%, and 25 minutes +/- 10; 80%, 0%, and 37 min +/- 19; and 100%, 0%, and 9 min +/- 4, respectively. Primary and secondary hemostasis were achieved in 50 (80%) and 60 (95%) of the 63 hemorrhagic arteries, respectively. Three hemorrhagic arteries in which transcatheter arterial embolization failed were treated with surgical repair. CONCLUSIONS: Although transcatheter arterial embolization with microcoils took a greater amount of time, transcatheter arterial embolization with NBCA or microcoils was more effective and feasible than that with gelatin sponge particle in terms of hemostasis and prevention of recurrent hemorrhage in a coagulopathic condition.

The effect of continuous veno-venous hemofiltration or direct hemoperfusion with polymyxin B-immobilized fiber on neutrophil respiratory oxidative burst in patients with sepsis and septic shock.

Neutrophil activates and injures tissues and organs during sepsis or septic shock. Blood purification therapies such as continuous veno-venous hemofiltration (CVVH) and direct hemoperfusion with polymyxin-immobilized fiber (PMX-DHP) have been used for the treatment of sepsis and septic shock, however, the effects of such therapies on neutrophil activation have previously been poorly understood. We sought to evaluate neutrophil reactive oxygen species (ROS), especially H2O2 production, in the pathophysiology of sepsis or septic shock and the effect of CVVH or PMX-DHP on neutrophil ROS. Seven critically ill septic patients requiring CVVH (and 12 matched septic patients who did not require CVVH as control) and seven septic shock patients treated with PMX-DHP were studied. We found that patients with sepsis or septic shock had significantly higher levels of neutrophil ROS compared with normal volunteers (183 +/- 42, 292 +/- 90, and 103 +/- 30) (P < 0.05, and < 0.005). Neutrophil ROS did not change over time in patients treated either with CVVH or without CVVH. In contrast, neutrophil ROS significantly inhibited PMX-DHP treatment in patients with septic shock (pretreatment; 292 +/- 88 vs. post-treatment; 205 +/- 93, P < 0.05). In conclusion, neutrophil ROS was significantly enhanced in the sepsis or septic shock affected patients. CVVH did not affect neutrophil ROS while PMX-DHP significant inhibited neutrophil ROS.
