BACKGROUND: Surgical site infection (SSI) is a risk in every operation. Infections negatively impact patient morbidity and mortality and increase financial demands. The aim of this study was to analyse SSI and its risk factors in patients after thoracic or lumbar spine surgery. METHODS: A six-year single-centre prospective observational cohort study monitored the incidence of SSI in 274 patients who received planned thoracic or lumbar spinal surgery for degenerative disease, trauma, or tumour. They were monitored for up to 30 days postoperatively and again after 1 year. All patients received short antibiotic prophylaxis and stayed in the eight-bed neurointensive care unit (NICU) during the immediate postoperative period. Risk factors for SSI were sought using multivariate logistic regression analysis. RESULTS: We recorded 22 incidences of SSI (8.03%; superficial 5.84%, deep 1.82%, and organ 0.36%). Comparing patients with and without SSI, there were no differences in age (p=0.374), gender (p=0.545), body mass index (p=0.878), spine diagnosis (p=0.745), number of vertebrae (p=0.786), spine localization (p=0.808), implant use (p=0.428), American Society of Anesthesiologists (ASA) Score (p=0.752), urine catheterization (p=0.423), drainage (p=0.498), corticosteroid use (p=0.409), transfusion (p=0.262), ulcer prophylaxis (p=0.409) and diabetes mellitus (p=0.811). The SSI group had longer NICU stays (p=0.043) and more non-infectious hospital wound complications (p<0.001). SSI risk factors according to our multivariate logistic regression analysis were hospital wound complications (OR 20.40, 95% CI 7.32-56.85, p<0.001) and warm season (OR 2.92, 95% CI 1.03-8.27, p=0.044). CONCLUSIONS: Contrary to the prevailing literature, our study did not identify corticosteroids, diabetes mellitus, or transfusions as risk factors for the development of SSI. Only wound complications and warm seasons were significantly associated with SSI development according to our multivariate regression analysis.

BACKGROUND: Nosocomial infection (NI) control is an important issue in neurocritical care due to secondary brain damage and the increased morbidity and mortality of primary acute neurocritical care patients. The primary aim of this study was to determine incidence of nosocomial infections and multidrug-resistant bacteria and seek predictors of nosocomial infections in a preventive multimodal nosocomial infection protocol in the neurointensive care unit (NICU). The secondary aim focused on their impact on stay, mortality and cost in the NICU. METHODS: A10-year, single-centre prospective observational cohort study was conducted on 3464 acute brain disease patients. There were 198 (5.7%) patients with nosocomial infection (wound 2.1%, respiratory 1.8%, urinary 1.0%, bloodstream 0.7% and other 0.1%); 67 (1.9%) with Extended spectrum beta-lactamase (ESBL); 52 (1.5%) with Methicillin-resistant Staphylococcus aureus (MRSA), nobody with Vancomycin-resistant enterococcus (VRE). The protocol included hygienic, epidemiological status and antibiotic policy. Univariate and multivarite logistic regression analysis was used for identifying predictors of nosocomial infection. RESULTS: From 198 NI patients, 153 had onset of NI during their NICU stay (4.4%; wound 1.0%, respiratory 1.7%, urinary 0.9%, bloodstream 0.6%, other 0.1%); ESBL in 31 (0.9%) patients, MRSA in 30 (0.9%) patients. Antibiotics in prophylaxis was given to 63.0% patients (59.2 % for operations), in therapy to 9.7% patients. Predictors of NI in multivariate logistic regression analysis were airways (OR 2.69, 95% CI 1.81-3.99, p<0.001), urine catheters (OR 2.77, 95% CI 1.00-7.70, p=0.050), NICU stay (OR 1.14, 95% CI 1.12-1.16, p<0.001), transfusions (OR 1.79, 95% CI 1.07-2.97, p=0.025) antibiotic prophylaxis (OR 0.50, 95% CI 0.34-0.74, p<0.001), wound complications (OR 2.30, 95% CI 1.33-3.97, p=0.003). NI patients had longer stay (p<0.001), higher mortality (p<0.001) and higher TISS sums (p<0.001) in the NICU. CONCLUSIONS: The presented preventive multimodal nosocomial infection control management was efficient; it gave low rates of nosocomial infections (4.2%) and multidrug-resistant bacteria (ESBL 0.9%, MRSA 0.9% and no VRE). Strong predictors for onset of nosocomial infection were accesses such as airways and urine catheters, NICU stay, antibiotic prophylaxis, wound complications and transfusion. This study confirmed nosocomial infection is associated with worse outcome, higher cost and longer NICU stay.

BACKGROUND: Dysnatremias are common and prognostically serious in neurocritical care. We studied whether a standardized sodium protocol would improve our neurocritical care of dysnatremias. METHODS: A 5-year prospective study of a standardized sodium protocol for 1,560 patients admitted with various brain diseases in an adult neurologic-neurosurgical intensive care unit (NNICU) was compared with a 5-year retrospective analysis of 1,440 patients without the sodium protocol. Hyponatremia was defined as serum sodium (SNa(+)) < 135 mmol/L and hypernatremia SNa(+ )> 150 mmol/L. The sodium protocol involved measuring SNa(+), serum, and urine osmolality, measured and calculated renal function parameters, fluid intake 40 mL/kg weight/day without hypotonic saline, thiazide, and desmopressin acetate in all normonatremic NNICU patients. RESULTS: In the protocol study, hyponatremia occurred slightly less often (15.7 versus 16.3% of patients; p = 0.684), hypernatremia was significantly higher (respectively 8.5% versus 5.2% of patients; p < 0.001), and no differences were noted in hypo/hypernatremia (p = 0.483). There were no differences in the incidence of hypo-osmolal hyponatremia (respectively 3.5% versus 3.5% of patients; p = 0.987), cerebral salt wasting (CSW; respectively 1.7% versus 1.7% of patients; p = 0.883), syndrome of inappropriate secretion of antidiuretic hormone (SIADH; respectively 0.1% versus 0.3% of patients; p = 0.152), central diabetes insipidus (CDI; respectively 1.0% versus 0.6% of patients; p = 0.149). In hyponatremia there were no differences in the Glasgow Coma Scale (GCS) score upon onset of hyponatremia (p = 0.294), NNICU mortality (respectively 1.0% versus 0.4% patients; p = 0.074), and bad outcome upon discharge from NNICU (respectively 5.1% versus 6.5% of patients; p = 0.101), but in hypernatremia GCS score upon onset (p < 0.001), mortality (respectively 2.8% versus 1.0%; p < 0.001), and bad outcome from NNICU (respectively 6.7% versus 2.7% patients; p < 0.001) were significantly higher. Multivariate logistic regression analysis showed that hypernatremia, compared with hyponatremia, was a significant predictor of mortality during NNICU stay (respectively odds ratio [OR]: 1.14; p = 0.003 versus OR; 5.3; p = 0.002). CONCLUSIONS: The standard sodium protocol lowered the frequency of SIADH, which was encountered in only one patient over 5 years. However, it did not significantly reduce the incidence and improve the outcome of hyponatremia. Hypernatremia occurred more often and had a higher mortality and worse outcome than hyponatremia, but these patients were neurologically worse upon its onset. The prospective study confirmed that CSW, SIADH, and CDI were not common in our neurocritical care.
