bookPart Delirium e Disfunção Cognitiva Pós-operatória(2017) XAVIER, Marcelo Souza; VALENTIN, Lívia Stocco Sanches; CARMONA, Maria José Carvalho- A pragmatic multi-center trial of goal-directed fluid management based on pulse pressure variation monitoring during high-risk surgery(2017) MALBOUISSON, Luiz Marcelo Sa; SILVA JR., Joao Manoel; CARMONA, Maria Jose Carvalho; LOPES, Marcel Rezende; ASSUNCAO, Murilo Santucci; VALIATTI, Jorge Luis dos Santos; SIMOES, Claudia Marques; AULER JR., Jose Otavio CostaBackground: Intraoperative fluid therapy guided by mechanical ventilation-induced pulse-pressure variation (PPV) may improve outcomes after major surgery. We tested this hypothesis in a multi-center study. Methods: The patients were included in two periods: a first control period (control group; n = 147) in which intraoperative fluids were given according to clinical judgment. After a training period, intraoperative fluid management was titrated to maintain PPV < 10% in 109 surgical patients (PPV group). We performed 1:1 propensity score matching to ensure the groups were comparable with regard to age, weight, duration of surgery, and type of operation. The primary endpoint was postoperative hospital length of stay. Results: After matching, 84 patients remained in each group. Baseline characteristics, surgical procedure duration and physiological parameters evaluated at the start of surgery were similar between the groups. The volume of crystalloids (4500 mL [3200-6500 mL] versus 5000 mL [3750-8862 mL]; P = 0.01), the number of blood units infused during the surgery (1.7 U [0.9-2.0 U] versus 2.0 U [1.7-2.6 U]; P = 0.01), the fraction of patients transfused (13.1% versus 32.1%; P = 0.003) and the number of patients receiving mechanical ventilation at 24 h (3.2% versus 9.7%; P = 0.027) were smaller postoperatively in PPV group. Intraoperative PPV-based improved the composite outcome of postoperative complications OR 0.59 [95% CI 0.35-0.99] and reduced the postoperative hospital length of stay (8 days [6-14 days] versus 11 days [7-18 days]; P = 0.01). Conclusions: In high-risk surgeries, PPV-directed volume loading improved postoperative outcomes and decreased the postoperative hospital length of stay.
bookPart Complicações Cardiocirculatórias(2017) AMORIM, Célio Gomes de; MANDIM, Beatriz Lemos da Silva; CARMONA, Maria José Carvalho- The effect of prior tetanic stimulation on train-of-four monitoring in paediatric patients A randomised open-label controlled trial(2017) CARLOS, Ricardo V.; BOER, Hans Donald de; TORRES, Marcelo Luis Abramides; CARMONA, Maria Jose CarvalhoBACKGROUND In clinical research, neuromuscular monitoring must present a stable response for a period of 2 to 5 min before administration of a neuromuscular blocking agent. The time required to reach this stable response may be shortened by applying a 5-s tetanic stimulus. OBJECTIVES The aim of this study was to test whether tetanic stimulation interferes with onset and recovery times after a single dose of rocuronium 0.6 mg kg(-1) followed by spontaneous recovery. DESIGN A randomised, open-label, controlled trial. SETTING A single-centre trial, study period from January 2014 to July 2015. PATIENTS Fifty children aged 2 to 11 years scheduled for elective paediatric surgery. INTERVENTION Patients were randomly allocated to receive either tetanic stimulation (group T) or not (group C) before calibration of the neuromuscular monitor. MAIN OUTCOME MEASURES Onset and recovery times. Initial and final T1 height, time to obtain initial T1 height stability and monitor settings were also analysed. RESULTS There was no significant difference in mean onset time [(C: 57.5 (+/- 16.9) vs. T: 58.3 (+/- 31.2) s; P = 0.917]. Mean times to normalised train-of-four (TOF) ratios of 0.7, 0.8 and 0.9 were significantly shorter in the tetanic stimulation group [C: 40.1 (+/- 7.9) vs. T: 34.8 (+/- 10) min; P = 0.047, C: 43.8 (+/- 9.4) vs. T: 37.4 (+/- 11) min; P = 0.045 and C: 49.9 (+/- 12.2) vs. T: 41.7 (+/- 13.1) min; P = 0.026, respectively]. The mean time required for T1 height stabilisation was similar in the two groups [C: 195.0 (+/- 203.0) vs. T: 116.0 (+/- 81.6) s; P = 0.093], but the initial and final T1 height values were significantly lower in the tetanic stimulation group (C: 98.0 vs. T: 82.7%; P<0.001 and C: 95.3 vs. T: 69.3%; P<0.001, respectively). CONCLUSION Tetanic stimulation shortened the mean times to normalised TOF ratios of 0.7, 0.8 and 0.9, but there was no difference in the mean onset time or the mean time required for T1 height stabilisation after a single dose of rocuronium 0.6 mg kg(-1) followed by spontaneous recovery in children aged 2 to 11 years.
bookPart Inovação, avaliação e incorporação tecnológica(2017) CANHISARES, Fernando Augusto Tavares; MALIK, Ana Maria; VANE, Matheus Fachini; CARMONA, Maria José Carvalho- Avaliação de hiperglicemia na sala de recuperação pós-anestésica(2017) PEREIRA, Vinicius Rodovalho; AZUMA, Rodrigo Akio; GATTO, Bruno Emanuel Oliva; SILVA JUNIOR, Joao Manoel; CARMONA, Maria Jose Carvalho; MALBOUISSON, Luiz Marcelo SaBackground and objectives: Hyperglycemia in surgical patients may cause serious problems. Analyzing this complication in this scenario contributes to improve the management of these patients. The aim of this study was to evaluate the prevalence of hyperglycemia in the post anesthetic care unit (PACU) in non-diabetic patients undergoing elective surgery and analyze the possible risk factors associated with this complication. Methods: We evaluated non-diabetic patients undergoing elective surgeries and admitted in the PACU. Data were collected from medical records through precoded questionnaire. Hyperglycemia was considered when blood glucose was >120 mg.dL(-1). Patients with hyperglycemia were compared to normoglycemic ones to assess factors associated with the problem. We excluded patients with endocrine-metabolic disorders, diabetes, children under 18 years, body mass index (BMI) below 18 or above 35, pregnancy, postpartum or breastfeeding, history of drug use, and emergency surgeries. Results: We evaluated 837 patients. The mean age was 47.8 +/- 16.1 years. The prevalence of hyperglycemia in the postoperative period was 26.4%. In multivariate analysis, age (OR 1.031, 95% CI 1.017-1.045); BMI (OR = 1.052, 95% CI 1.005-1.101); duration of surgery (OR = 1.011, 95% CI 1.008-1.014), history of hypertension (OR = 1.620, 95% CI 1.053-2.493), and intraoperative use of corticosteroids (OR = 5.465, 95% CI 3.421-8.731) were independent risk factors for postoperative hyperglycemia. Conclusion: The prevalence of hyperglycemia was high in the PACU, and factors such as age, BMI, corticosteroids, blood pressure, and duration of surgery are strongly related to this complication.

- Independent early predictors of mortality in polytrauma patients: a prospective, observational, longitudinal study(2017) COSTA, Luiz Guilherme V. da; CARMONA, Maria Jose C.; MALBOUISSON, Luiz M.; RIZOLI, Sandro; ROCHA-FILHO, Joel Avancini; CARDOSO, Ricardo Galesso; AULER-JUNIOR, Jose Otavio C.OBJECTIVES: Trauma is an important public health issue and associated with substantial socioeconomic impacts and major adverse clinical outcomes. No single study has previously investigated the predictors of mortality across all stages of care (pre-hospital, emergency room, surgical center and intensive care unit) in a general trauma population. This study was designed to identify early predictors of mortality in severely injured polytrauma patients across all stages of care to provide a better understanding of the physiologic changes and mechanisms by which to improve care in this population. METHODS: A longitudinal, prospective, observational study was conducted between 2010 and 2013 in Sao Paulo, Brazil. Patients submitted to high-energy trauma were included. Exclusion criteria were as follows: injury severity score <16, <18 years old or insufficient data. Clinical and laboratory data were collected at four time points: pre-hospital, emergency room, and 3 and 24 hours after hospital admission. The primary outcome assessed was mortality within 30 days. Data were analyzed using tests of association as appropriate, nonparametric analysis of variance and generalized estimating equation analysis (p<0.05). ClinicalTrials.gov: NCT01669577. RESULTS: Two hundred patients were included. Independent early predictors of mortality were as follows: arterial hemoglobin oxygen saturation (p<0.001), diastolic blood pressure (p<0.001), lactate level (p<0.001), Glasgow Coma Scale score (p<0.001), infused crystalloid volume (p<0.015) and presence of traumatic brain injury (p<0.001). CONCLUSION: Our results suggest that arterial hemoglobin oxygen saturation, diastolic blood pressure, lactate level, Glasgow Coma Scale, infused crystalloid volume and presence of traumatic brain injury are independent early mortality predictors.

- Atorvastatin for high-risk statin-naive patients undergoing noncardiac surgery: The Lowering the Risk of Operative Complications Using Atorvastatin Loading Dose (LOAD) randomized trial(2017) BERWANGER, Otavio; SILVA, Pedro G. M. de Barros e; BARBOSA, Roberto Ramos; PRECOMA, Dalton Bertolim; FIGUEIREDO, Estevao Lanna; HAJJAR, Ludhmila Abrahao; KRUEL, Cleber Dario Pinto; ALBOIM, Carolina; ALMEIDA, Adail Paixao; DRACOULAKIS, Marianna Deway Andrade; VARGAS FILHO, Hugo; CARMONA, Maria Jose Carvalho; MAIA, Lilia Nigro; OLIVEIRA FILHO, Joao Bosco de; SARAIVA, Jose Francisco Kerr; SOARES, Rafael M.; DAMIANI, Lucas; PAISANI, Denise; KODAMA, Alessandra A.; GONZALES, Beatriz; IKEOKA, Dimas T.; DEVEREAUX, Philip J.; LOPES, Renato D.Background Preliminary evidence suggests that statins may prevent major perioperative vascular complications. Methods We randomized 648 statin-naive patients who were scheduled for noncardiac surgery and were at risk for a major vascular complication. Patients were randomized to a loading dose of atorvastatin or placebo (80 mg anytime within 18 hours before surgery), followed by a maintenance dose of 40 mg (or placebo), started at least 12 hours after the surgery, and then 40 mg/d (or placebo) for 7 days. The primary outcome was a composite of all-cause mortality, nonfatal myocardial injury after noncardiac surgery, and stroke at 30 days. Results The primary outcome was observed in 54 (16.6%) of 326 patients in the atorvastatin group and 59 (18.7%) of 316 patients in the placebo group (hazard ratio [HR] 0.87, 95% CI 0.60-1.26, P = .46). No significant effect was observed on the 30-day secondary outcomes of all-cause mortality (4.3% vs 4.1%, respectively; HR 1.14, 95% CI 0.53-2.47, P = .74), nonfatal myocardial infarction (3.4% vs 4.4%, respectively; HR 0.76, 95% CI 0.35-1.68, P = .50), myocardial injury after noncardiac surgery (13.2% vs 16.5%; HR 0.79, 95% CI 0.53-1.19, P = .26), and stroke (0.9% vs 0%, P = .25). Conclusion In contrast to the prior observational and trial data, the LOAD trial has neutral results and did not demonstrate a reduction in major cardiovascular complications after a short-term perioperative course of statin in statin-naive patients undergoing noncardiac surgery. We demonstrated, however, that a large multicenter blinded perioperative statin trial for high-risk statin-naive patients is feasible and should be done to definitely establish the efficacy and safety of statin in this patient population.
