Objective:
To define the epidemiological profile and the main determinants of morbidity and mortality in noncardiac high surgical risk patients in Brazil.
Methods:
This was a prospective, observational and multicenter study. All noncardiac surgical patients admitted to intensive care units, i.e., those considered high risk, within a 1-month period were evaluated and monitored daily for a maximum of 7 days in the intensive care unit to determine complications. The 28-day postoperative, intensive care unit and hospital mortality rates were evaluated.
Results:
Twenty-nine intensive care units participated in the study. Surgeries were performed in 25,500 patients, of whom 904 (3.5%) were high-risk (95% confidence interval – 95%CI 3.3% – 3.8%) and were included in the study. Of the participating patients, 48.3% were from private intensive care units, and 51.7% were from public intensive care units. The length of stay in the intensive care unit was 2.0 (1.0 – 4.0) days, and the length of hospital stay was 9.5 (5.4 – 18.6) days. The complication rate was 29.9% (95%CI 26.4 – 33.7), and the 28-day postoperative mortality rate was 9.6% (95%CI 7.4 – 12.1). The independent risk factors for complications were the Simplified Acute Physiology Score 3 (SAPS 3; odds ratio – OR = 1.02; 95%CI 1.01 – 1.03) and Sequential Organ Failure Assessment Score (SOFA) on admission to the intensive care unit (OR = 1.17; 95%CI 1.09 – 1.25), surgical time (OR = 1.001, 95%CI 1.000 – 1.002) and emergency surgeries (OR = 1.93, 95%CI, 1.10 – 3.38). In addition, there were associations with 28-day mortality (OR = 1.032; 95%CI 1.011 – 1.052), SAPS 3 (OR = 1.041; 95%CI 1.107 – 1.279), SOFA (OR = 1.175, 95%CI 1.069 – 1.292) and emergency surgeries (OR = 2.509; 95%CI 1.040 – 6.051).
Conclusion:
Higher prognostic scores, elderly patients, longer surgical times and emergency surgeries were strongly associated with higher 28-day mortality and more complications during the intensive care unit stay.

However, a significant portion of these patients experience intestinal motility problems. Administration of enteral nutrition by means of tubes placed in the post-pyloric position has been suggested to improve the nutrition tolerance. The aim of this study was to compare the rate of successful post-pyloric placement using a real-time electromagnetic positioning device to the success rate using the conventional placement method. METHODS: This was a prospective, randomized and controlled study, conducted in a tertiary hospital over a period of three months. The patients were randomized to one of two groups: electromagnetically guided system group, whose patients underwent real-time monitoring of post-pyloric tube placement; or the control group, whose patients underwent tube placment using to the conventional blinded technique. The rates of successful post-pyloric placement and the procedure times were assessed and compared between the groups. RESULTS: Thirty-seven patients were enrolled, 18 in the electromagnetic group and 19 in the control group. The final tube position was evaluated using radiography. The electromagnetic guided group showed better success rates and shorter procedure times when compared to the control group. Additionally, in the electromagnetic guided group, higher pH values were found in the fluids aspirated from the probe, suggesting successful postpyloric placement. CONCLUSION: The electromagnetically guided method provided better placement accuracy than did the conventional technique.

Views0See moreOBJECTIVES: An increased lactate level is classically considered a marker for poorer prognosis, however little information is available on intraoperative lactate’s kinetics and its connection with prognosis. This study aimed to evaluate the time when perioperative lactate is most relevant for prognosis. METHODS: This was an observational prospective study conducted in a tertiary hospital. Patients with requested intensive care unit postoperative stay, aged > 18 years, undergoing major surgery were included. Palliative surgery patients and those with heart and/or severe liver failure were excluded. Arterial lactate levels were measured immediately before the surgery start (T0), after anesthesia induction (T1), 3 hours after the surgery start (T2), intensive care unit admission (T3) and 6 hours after the intensive care unit admission (T4). RESULTS: Sixty seven patients were included. The mean lactate values for the patients’ T0, T1, T2 and T4 were 1.5 ± 0.8 mmol/L, 1.5 ± 0.7 mmol/L, 1.8 ± 1.2 mmol/L, 2.7 ± 1.7 mmol/L and 3.1 ± 2.0 mmol/L, respectively. The hospital mortality rate was 25.8%, and surviving and non-surviving patients lactate values in the intensive care unit were 2.5 ± 1. and 4.8 ± 2.8 mmol/L (P < 0.0001), respectively. The other times measurements showed no statistically significant differences between the groups. CONCLUSIONS: In surgical patients, intraoperative arterial lactate levels failed to show a predictive value; however during the postoperative period, this assessment was shown to be useful for hospital mortality prediction.

METHODS: This was a prospective observational trial in patients over 18 years of age, admitted in an intensive care unit and under mechanical ventilation, during one year. Patients were divided into two groups according to age: Group 1 – patients over 65 years old; and Group 2, 65 years old or younger. RESULTS: eighty one mechanic ventilation patients were included, 62 aged and 18 younger, mean ages from aged was 76 years, while in the younger it was 56 years. As compared to the control, aged patients had longer mechanic ventilation time , higher intensive care unit and hospital mortality: 63.1% versus 26.3% and 74.2% versus 47.4% (P<0.05), respectively. In addition, the aged under mechanic ventilation had increased desintubation failures, difficult ventilatory weaning and deaths directly related to respiratory dysfunction. The mechanic ventilation time was an independent risk factor for death in the intensive care unit in aged patients (OR= 2.7, p=0.02). The area under the ROC curve of mechanic ventilation about intensive care unit death was 0.92 (95% CI 0.85-0.97, p (area 0.5)=0.0001), cutoff point of 4 days, sensitivity 89.4% and specificity 77.1%. CONCLUSIONS: Mechanic ventilation patients over 65years of age have a worse prognosis than the younger, and the longer the mechanic ventilation time, the higher will be intensive care mortality.
