Evaluation of the registry DIALYREG for the assessment of continuous renal replacement techniques in the critically ill patient

Continuous renal replacement techniques (CRRT) can induce complications and monitoring is crucial to ensure patient safety. We designed a prospective multicenter observational and descriptive study using the DIALYREG registry, an online database located on a REDCap web-based platform that allows real-time data analysis. Our main objective was to identify CRRT-related complications in our intensive care units (ICUs) and implement security measures accordingly. From January 2019 to December 2020, we included 323 patients with admission diagnoses of medical illness (54%), sepsis (24%), postoperative care (20%), and trauma (2%). CRRT indications were homeostasis (42%), oliguria (26%), fluid overload (15%), and hemodynamic optimization (13%). The median initial therapy dose was 30 ml/kg/h (IQR 25-40), and dynamic adjustment was performed in 61% of the treatments. Sets were anticoagulated with heparin (40%), citrate (38%) or no anticoagulation (22%). Citrate anticoagulation had several advantages: more frequent dynamic CRRT dose adjustment (77% vs. 58% with heparin and 56% without anticoagulation, p < 0.05), longer duration of set (median of 55 h, IQR 24-72 vs. 23 h, IQR 12-48 with heparin and 12 h, IQR 12-31 without anticoagulation, p < 0.05), less clotting of the set (26% vs. 46.7% with heparin, p < 0.05), and lower incidence of hypophosphatemia (1% citrate vs. 6% with heparin and 5% without anticoagulation). It was also safe and effective in subgroup analysis of patients with liver disease or sepsis. The main global complications were hypothermia (16%), hypophosphatemia (13%) and metabolic acidosis (10%). Weaning of the therapy was achieved through early discontinuation (56%), nocturnal therapy transition (26%) and progressive SLED (18%). 52% of the patients were discharged from the hospital, while 43% died in the ICU and 5% died during hospitalization. We can conclude that the DIALYREG registry is a feasible tool for real-time control of CRRT in our ICU.

[Dysautonomic seizures in patients admitted to an intensive care unit following severe traumatic brain injury]

AIM

To describe clinical and radiologic features of dysautonomic crisis after severe traumatic brain injury and its influence in the clinical situation six months later.

PATIENTS AND METHODS

Retrospective, observatory study of seven patients after severe head injury, with dysautonomic crisis, admitted in the Critical Care Unit (CCU) during six months. No interventions. Its clinical features, its association with intracranial pressure and the treatment for Dysautonomic crisis they have received were extracted from the computed clinical report. We have evaluated his neurologic prognosis with the Jennet-Bond scale and his radiologic characteristics with the Gennarelly scale.

RESULTS

Dysautonomic crisis began in the first week if the patients didn't received neuromuscular blocks drugs and they continued when the patients were discharged from the CCU in a young population with an initial Glasgow scale coma of 5 points. We didn't wait a special radiologic pattern. After the next six months, crisis were disappeared in 86% of patients and all patients reached a good neurologic level in the Jennet-Bond scale.

CONCLUSIONS

Dysautonomic crisis appeared early in young men after severe head injury. We didn't find a radiologic pattern that predisposes the dysautonomic crisis. They didn't interfere the recovering six months after head injury.
