ABSTRACT

The role of extracorporeal membrane oxygenation (ECMO) as a therapeutic strategy has been very well documented for over a decade now with consistently positive remarks. The aim of the present study was analyzing the outcome of ECMO application in our lung transplant program, especially the feasibility and safety of our ECMO approach. Therefore, we retrospectively analyzed the data of 15 patients recipients requiring ECMO support. We analyzed clinical data, complications, and survival of the lung-transplanted population that needed ECMO support at our institution from 2006-2009. During that period, 19 applications of ECMO were done on 15 adult patients with the following indications: primary graft dysfunction (10 patients), "bridge to transplantation" (five), pulmonary hypertension (three), and severe acute respiratory distress syndrome (one). At 28 days, the overall survival was 93% (14 of 15 patients) and 12 of these patients (80%) survived at least 6 months. Complications included acute renal insufficiency with temporary need of renal replacement therapy (53%), bleeding (33%), critical illness polyneuropathy (66%), and reversible thrombocytopenia (73%). Based on the evaluation of the patients in this analysis, ECMO seems to be a safe therapeutic approach in lung transplant recipients with severe respiratory failure directly after transplantation.

ABSTRACT

PURPOSE: The purpose of the study was to assess long-term mortality after an intensive care unit (ICU) stay and to test the hypotheses that (1) quality of life improves over time and (2) predictions of outcome made by caregivers during an ICU stay are reliable. MATERIALS AND METHODS: Data from a 6-bed university medical ICU were reviewed. Telephone assessment of mortality and interviews/questionnaires 9 years after an ICU stay were performed. Comparison of caregivers' predictions of survival/quality of life with reported outcome was done. RESULTS: Of 409 patients surviving 6 months after ICU, 334 were included and 146 of these had died. Age, diagnostic group, and severity of illness were significant factors for mortality (P < .0001 for all 3). Of all survivors, 59% described their overall quality of life as good and 35% as fair. Physical dependency was significantly related to length of hospital stay (P < .01), whereas quality of life was related to admission age (P < .05). Caregivers' predictions concerning both survival and quality of life seemed reliable, with physicians' predictions being more reliable than nurses' (P < .05). CONCLUSIONS: Mortality is high 9 years after ICU stay. Quality of life may deteriorate for some individuals; however, overall quality of life for most survivors remains acceptable and may even improve. Long-term outcome predictions made by caregivers during the ICU stay seem accurate.

ABSTRACT

OBJECTIVE: Assess optimal equation to noninvasively estimate intracranial pressure (eICP) and cerebral perfusion pressure (eCPP) following severe traumatic brain injury (TBI) using transcranial color-coded duplex sonography (TCCDS). DESIGN AND SETTING: This is an observational clinical study in a university hospital. PATIENTS: A total of 45 continuously sedated (BIS < 50), normoventilated (paCO(2) > 35 mmHg), and non-febrile TBI patients. METHODS: eICP and eCPP based on TCCDS-derived flow velocities and arterial blood pressure values using three different equations were compared to actually measured ICP and CPP in severe TBI patients subjected to standard treatment. Optimal equation was assessed by Bland-Altman analysis. RESULTS: The equations: ICP = 10:927 x PI(pulsatility index) - 1:284 and CPP = 89:646 - 8:258 PI resulted in eICP and eCPP similar to actually measured ICP and CPP with eICP 10.6 +/- 4.8 vs. ICP 10.3 +/- 2.8 and eCPP 81.1 +/- 7.9 vs. CPP 80.9 +/- 2.1 mmHg, respectively. The other two equations, eCPP = (MABP x EDV)/mFV + 14 and eCPP = mFV / (mFV - EDV)] x (MABP - RRdiast), resulted in significantly decreased eCPP values: 72.9 +/- 10.1 and 67 +/- 19.5 mmHg, respectively. Superiority of the first equation was confirmed by Bland-Altman revealing a smallest standard deviations for eCPP and eICP. CONCLUSIONS: TCCDS-based equation (ICP = 10.927 x PI - 1.284) allows to screen patients at risk of increased ICP and decreased CPP. However, adequate therapeutic interventions need to be based on continuously determined ICP and CPP values.
