Background and Objectives: Hemodynamic changes are observed during cesarean section under spinal anesthesia. Non-invasive blood pressure (BP) and heart rate (HR) measurements are performed to diagnose these changes, but they are delayed and inaccurate. Other monitors such as filling pressure and cardiac output (CO) catheters with external calibration are very invasive or inaccurate. The objective of the present study was to report the cardiac output measurements obtained with a minimally invasive uncalibrated monitor (LiDCO rapid) in patients undergoing cesarean section under spinal anesthesia. Case report: After approval by the Ethics Commission, four patients agreed to participate in this study. They underwent cesarean section under spinal anesthesia while at the same time being connected to the LiDCO rapid by a radial artery line. Cardiac output, HR, and BP were recorded at baseline, after spinal anesthesia, after fetal and placental extraction, and after the infusion of oxytocin and metaraminol. We observed a fall in BP with an increase of HR and CO after spinal anesthesia and oxytocin infusion; and an increase in BP with a fall in HR and CO after bolus of the vasopressor. Conclusions: Although this monitor had not been calibrated, it showed a tendency for consistent hemodynamic data in obstetric patients and it may be used as a therapeutic guide or experimental tool.

    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 Costa
    Background: 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.

    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 Carvalho
    BACKGROUND 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.

    (2011) CAVALCANTE, Fernanda Paula; NANI, Ricardo Souza; ROCHA FILHO, Joel Avancini; AULER JUNIOR, Jose Otavio Costa; CARMONA, Maria Jose Carvalho; MACHADO, Marcel Cerqueira Cesar
    Cavalcante FP, Nani RS, Rocha Filho JA, Auler Junior JOC, Carmona MJC, MachadoMCC - Experimental Model of Non-Controlled Hemorrhagic Shock in Pigs. Background and objectives: A better understanding of pathophysiologic changes associated to trauma and hemorrhagic shock can help the development of therapies capable of reducing trauma-related mortality. The objective of this study was to describe a model of non-controlled hemorrhagic shock in pigs. Methods: Animals received ketamine and midazolam as pre-anesthetic medications. Anesthesia was induced with propofol, and tracheal intubation was performed with the animals on spontaneous ventilation. After intubation neuromuscular blockade was performed. Animals were maintained in controlled mechanical ventilation and normocapnia. Anesthesia was maintained with propofol and fentanyl as needed. Saline was infused during the entire preparation period. Monitoring: Cardioscope, pulse oximeter, invasive blood pressure, volumetric catheter in the pulmonary artery, and urine output by cystostomy were used. Experimental model: after the initial recording of hemodynamic, metabolic, and coagulation variables, right subcostal incision and left lobe liver biopsy were performed. Anesthetic infusion was reduced while the infusion of saline was interrupted. An incision 12 cm long 2 cm deep was performed in the right liver lobe followed by digital divulsion of the wound. During the hemorrhagic phase, an aspiration probe was placed close to the wound and the volume of aspirated blood was recorded. When mean arterial pressure reached 40 mmHg and bleeding was above 700 mL the intervention phase was initiated according to the type of study. Conclusion: The development of experimental models to reduce high mortality and costs related to trauma is important.

    Metabolic Acidosis Assessment in High-Fisk Surgeries: Prognostic Importance
    (2016) SILVA JR., Joao Manoel; OLIVEIRA, Amanda Maria Ribas Rosa de; NOGUEIRA, Fernando Augusto Mendes; VIANNA, Pedro M. M.; AMENDOLA, Cristina Prata; CARMONA, Maria Jose Carvalho; MALBOUISSON, Luiz M. Sa
    BACKGROUND: Metabolic acidosis frequently is present in surgical patients; however, different types of metabolic acidosis (hyperlactatemia, hyperchloremia, and others) may have different relationships to perioperative outcomes. We hypothesized that in postoperative surgical patients, distinctive types of metabolic acidosis would correlate differently with the outcomes of high-risk surgeries. METHODS: A prospective, multicenter observational study was performed in 3 different tertiary care hospitals. Patients who required postoperative admission to the intensive care unit (ICU) were included in this study. Patients with a short life expectancy (those with untreated cancer and limited treatment), hepatic failure, renal failure, or a diagnosis of diabetes were excluded. Patients were classified at ICU admission according to the presence and type of metabolic acidosis into 4 groups: those without acidosis, those with a base excess <-4 mmol/L and albumin-corrected anion gap <= 12 mmol/L (hyperchloremic), those with a base excess <-4 mmol/L and increased albumin-corrected anion gap >12 mmol/L, and those with a base excess <-4 mmol/L and hyperlactatemia >2 mmol/L. Furthermore, patients were reclassified 12 hours after admission to the ICU to verify the metabolic acidosis behavior and outcome differences among the groups. RESULTS: The study included 618 patients. The incidence of acidosis at ICU admission was 59.1%; 23.9% presented with hyperchloremia, 21.3% with hyperlactatemia, 13.9% with increased anion gap, and 40.9% of the patients presented without metabolic acidosis. Patients whose metabolic acidosis persisted for 12 hours had an incidence of ICU complications rates in hyperlactatemia group of 68.8%, increased anion gap of 68.6%, hyperchloremic of 65.8%, and those without acidosis over 12 hours of 59.3%. A Cox regression Model for postoperative 30-day mortality showed: in hyperlactatemic acidosis, hazard ratio (HR) = 1.74, 95% confidence interval (Cl) = 1.02-2.96; increased anion gap acidosis, HR = 1.68, 95% CI = 0.85-3.81; hyperchloremic acidosis, HR = 1.47, 95% CI = 0.75-2.89, and 10.3% of 30-day mortality rate in patients without acidosis. An adjusted survival curve by Cox regression found a worse 30-day survival in the hyperlactatemic group compared with the other groups (P =.03). Furthermore, in multiple comparisons among groups, patients with hyperlactatemic acidosis were more likely to develop renal dysfunction (P <.001) up to the seventh day postoperatively. CONCLUSIONS: We found that among patients with different types of acidosis, patients who developed hyperlactatemic metabolic acidosis postoperatively showed greater rates of renal dysfunction within 7 days and hyperlactatemic acidosis represented an independent factor on 30-day mortality in high-risk surgical patients.

    Evaluation of Cytokine Levels and Pulmonary Function in Patients Undergoing Coronary Artery Bypass Graft
    (2011) MACHADO, Luciano Brandao; NEGRI, Elnara Marcia; BONAFE, Wanderley Wesley; SANTOS, Luciana Moraes; MALBOUISSON, Luis Marcelo Sa; CARMONA, Maria Jose Carvalho
    The Summary: Machado LB, Negri EM, Bonafe WW, Santos LM, Malbouisson LMS, Carmona MJC - Evaluation of Cytokine Levels and Pulmonary Function in Patients Undergoing Coronary Artery Bypass Grafts. Background and objectives: Systemic inflammatory response syndrome is commonly observed in coronary artery bypass grafts (CABG) with cardiopulmonary bypass (CB). The objective of this study was to evaluate the systemic and pulmonary levels of cytokines and their correlation with lung function in patients undergoing myocardial revascularization (MR) with CB. Methods: This study was approved by the Institutional Ethics Committee, and 13 patients undergoing MR with CB were evaluated. After anesthetic induction and at the end of CB, plasma and bronchoalveolar lavage levels of IL-1 beta, IL-6, IL-8, IL-10, and TNF-alpha were determined. The duration of CB and surgery, PaO(2)/FiO(2) ratio, alveolar-arterial oxygen gradient (A-a gradient), shunt, and lung compliance were evaluated. Results were submitted to analysis of variance for repeated measurements ((star)p < 0.05) and Spearman's correlation coefficient. Results: We observed increased levels of cytokines in plasma and bronchoalveolar lavage after CB and a direct relationship between the increase in IL-beta and decrease in lung compliance (p = 0.0439), as well as the inverse relationship between the increase in IL-10 and a decrease in compliance (p = 0.0325). The increase in IL-6 was directly related to the duration of CB (p = 0.012), while the increase in IL-8 was directly related to the duration of surgery (p < 0.0001). Levels of interleukin-1 beta, IL-8, and TNF-alpha in bronchoalveolar lavage were higher than in plasma. Conclusions: There is an increase in cytokine levels in plasma and bronchoalveolar lavage after CB, as well as a correlation between increased cytokine levels and CB duration and surgery and changes in lung compliance.
