RESUMO
BACKGROUND: The urine biomarkers tissue inhibitor of metalloproteinases-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been validated for predicting and stratifying AKI. In this study, we analyzed the utility of these biomarkers for distinguishing between transient and persistent AKI in the early phase of septic shock. METHODS: We performed a prospective, multicenter study in 11 French ICUs. Patients presenting septic shock, with the development of AKI within the first 6 h, were included. Urine [TIMP-2]*[IGFBP7] was determined at inclusion (0 h), 6 h, 12 h, and 24 h. AKI was considered transient if it resolved within 3 days. Discriminative power was evaluated by receiver operating characteristic (ROC) curve analysis. RESULTS: We included 184 patients, within a median [IQR] time of 1.0 [0.0-3.0] h after norepinephrine (NE) initiation; 100 (54%) patients presented transient and 84 (46%) presented persistent AKI. Median [IQR] baseline urine [TIMP-2]*[IGFBP7] was higher in the persistent AKI group (2.21 [0.81-4.90] (ng/ml)2/1000) than in the transient AKI group (0.75 [0.20-2.12] (ng/ml)2/1000; p < 0.001). Baseline urine [TIMP-2]*[IGFBP7] was poorly discriminant, with an AUROC [95% CI] of 0.67 [0.59-0.73]. The clinical prediction model combining baseline serum creatinine concentration, baseline urine output, baseline NE dose, and baseline extrarenal SOFA performed well for the prediction of persistent AKI, with an AUROC [95% CI] of 0.81 [0.74-0.86]. The addition of urine [TIMP-2]*[IGFBP7] to this model did not improve the predictive performance. CONCLUSIONS: Urine [TIMP-2]*[IGFBP7] measurements in the early phase of septic shock discriminate poorly between transient and persistent AKI and do not improve clinical prediction over that achieved with the usual variables.

The "perioperative" period for elderly patients is prone to a significant level of morbidity and mortality. Chronological age and comorbidities are the main causes of mortality. Loco-regional anaesthesia is used in 50% of cases. When general anaesthesia is used, invasive monitoring is the rule, with titration of medication and pain treatment. Cognitive dysfunctions are related to age rather than the anaesthetic technique. The aim is for early rehabilitation perhaps through ambulatory care.

With the development of ambulatory surgery, there may be questions about the legal risk of this procedure. Indeed, the discharge of the patient from the hospital on the same day as the medical treatment raises the problem of monitoring and supervising potential complications, with a substantial delay in medical care, and the anaesthesiologists can be confronted with new areas of liability. This article specifies the French statutory and legal framework of the ambulatory surgery, and shows how the responsibility of the anaesthesiologist can be involved during patient care at all steps. The analysis of judicial precedent shows that the legal risk for the anaesthesiologist also exists in outpatient surgery. Surgery and anaesthesia are medical procedures involving a relatively high risk of damage for the patient. The damage can be attributed to malpractice from one or several health care professionals or to a medical complication (abnormal damage not related to malpractice and independent of past medical history of the patient). In the light of the ongoing and significant development in ambulatory surgery, there may be questions about the legal risk of this procedure. Indeed, the discharge of the patient from the hospital on the same day as the medical treatment raises the problem of monitoring and supervising potential complications, with a substantial delay in medical care. If the patient suffers any damage, the surgeon, the anaesthesiologist and in some cases, the hospital will have to answer in courts: the surgeon for the surgical procedure, the anaesthesiologist for the medical care and the hospital as the liable institution. After having specified the statutory framework of ambulatory surgery, we will see how the responsibility of the anaesthesiologist can be involved during patient care at all steps.
