Observational StudyPrediction of the renal replacement therapy requirement in mechanically ventilated critically ill patients by combining biomarkers for glomerular filtration and tubular damage.
Mechanically ventilated critically ill patients with high severity score indices need a very cautious therapeutic approach. Considering that inappropriate decisions on renal replacement therapy (RRT) initiation may promote unwanted adverse effects, we evaluated whether a panel of novel and traditional renal markers is superior to conventional renal marker in predicting RRT requirements in this group of patients. ⋯ Specific markers of kidney dysfunction and of kidney damage can be successfully combined to increase the prognostic capability for RRT initiation. The presence of AKI affects diagnostic performance. Without an established AKI on ICU admission, future RRT requirement was better predicted by the combination of illness severity with a marker of glomerular filtration rate. With AKI on ICU admission a combination of the marker of glomerular filtration rate with one of tubular injury proved best.

Procalcitonin, as an early biomarker of colorectal anastomotic leak, facilitates enhanced recovery after surgery.
Procalcitonin (PCT) is a biomarker used to help sepsis diagnosing and monitoring and guide antibiotic therapy. Anastomotic leak (AL) after colorectal surgery is a severe complication associated with relevant short- and long-term sequelae. The aim of our study is to assess the predictive value of PCT levels to early diagnose AL after colorectal surgery. ⋯ Compared with more established biochemical values such as CRP and WBC, PCT is an earlier, more sensitive, and reliable marker of AL. Increased PCT levels in early PODs after colorectal surgery may provide a more effective way to detect AL, before clinical symptoms appear. Moreover, normal PCT values might be also a useful marker to facilitate a safe and early discharge of selected patients after colorectal surgery.

Duration of prehospital intubation is not a risk factor for development of early ventilator-associated pneumonia.
Ventilator-associated pneumonia (VAP) is a significant cause of morbidity and mortality among critically ill patients with trauma. Few VAP prevention strategies have been studied in the prehospital environment. The objectives of this study are to measure the association between duration of prehospital intubation and intubation location with subsequent incidence of early (within 5 days) VAP. ⋯ Duration of prehospital intubation and intubation location were not different in patients with trauma who developed early VAP. Further prospective analyses should be conducted to better elucidate the effect of prehospital management on the development of traditionally in-hospital complications.

Renal outcome after vancomycin treatment and renal replacement therapy in patients with severe sepsis and septic shock: A retrospective study.
Acute kidney injury during systemic infections is common; however, renal outcome is poorly investigated. The increase of multiresistant pathogens leads to the use of potential nephrotoxic antibiotics as vancomycin. We investigated the impact of vancomycin and renal replacement therapy (RRT) for renal recovery during sepsis. ⋯ Estimated GFR at ICU admission predicts renal outcome, whereas the use of vancomycin increases the probability of a prolonged need for RRT at discharge from ICU. The use of alternative antibiotics for certain patients, indicated by eGFR at admission, might be considered.

Observational StudyCorrelation of corrected flow time in the carotid artery with changes in intravascular volume status.
Assessment of volume status remains a challenge in critical care. Our purpose was to determine if Doppler waveform analysis of carotid artery blood flow correlates with changes in volume status. ⋯ Intravenous fluid administration in dehydrated patients resulted in significant changes in FTc in the carotid artery despite no change in vital signs. Corrected flow time measured from carotid arterial blood flow may be a useful means of assessing volume status in volume-depleted patients.
