An index with high diagnostic accuracy can properly identify the Patients ready for weaning from mechanical ventilation and prevents premature weaning and its complications. Two of the introduced weaning indicators are RSBI and CROP but their predictive value in predicting the outcome of weaning from mechanical ventilation is different or contradictory. <br /><strong>Objectives:</strong> This study was to Compare RSBI and CROP in predicting the outcome of weaning from mechanical ventilation in patients admitted to ICU. <br /><strong>Materials and methods: </strong>This prospective, single-blind study was performed on 80 adult patients who were on mechanical ventilation for more than 24 hours in 3 ICUs (Internal-General-stroke) of Mashhad Ghaem hospital from October 2015 to May 2016. All the patients ready for weaning were identified and studied in one group. All of them were ventilated with PSV mode with minimum support for 30 mins. If the patient’s vital signs were stable during those 30 mins, we measured the required respiratory variables and arterial blood gas values to calculate CROP and RSBI. Then the SBT was performed, with a T-piece for 120 mins. finally the diagnostic accuracy of each index was evaluated according to the weaning outcome and prediction of indexes. <br /><strong>Results: </strong>There were 57 successful and 23 unsuccessful weaning cases. The specificities were CROP 0.85 and RSBI 98.2. The sensitivities were CROP 0.75 and RSBI 0.26. The diagnostic accuracy were CROP 85.2 and RSBI 77.5. The new threshold value obtained in this study was very different for RSBI. <br /><strong>CONCLUSIONS</strong>: According to the analysis performed by the cut-off points obtained in previous studies, CROP index has the highest diagnostic accuracy, sensitivity and specificity were both high. The cut-off point of RSBI previously reported for non-homogeneous patients population is not extensible to all with different etiologies.<strong>Background: </strong>Usage of indicators to predict the outcome of weaning from the ventilator is a controversial issue.

Different compounds including crystalloid and colloidal solutions are proposed for this purpose. There is a lot of evidence that there is a clinically difference in the use of various crystalloids. In this study, the effect of two methods of fluid therapy with Ringer’s Lactate and Ringer’s solution on acid-base balance and postoperative complications in patients candidate for elective operation was studied. <br /><strong>Subjects & Methods:</strong> This clinical trial study was performed on 86 patients undergoing major anesthetic surgery in ASA class I and II and had no heart and kidney problems. The fluid therapy was performed with a ringer's lactate solution in one group (n = 43) and in the other group with ringer solution (n = 43). Before starting surgery, blood samples were taken for hemoglobin, hematocrit, albumin and electrolytes, and arterial blood samples for analysis of arterial blood gas.

However, the amount of potassium and calcium significantly increased after the liquid therapy in the ringer's lactate group and the amount of chlorine in the ringer group significantly increased. Bicarbonate and PH were increased after fluid therapy in ringer's lactate group and decreased significantly in ringer group. Also, the amount of bleeding during operation and duration of postoperative hospitalization was higher in ringer group, but this difference was not statistically significant. Nausea and vomiting were reported more in the ringer group than in the ringer's lactate group, but this difference was not statistically significant. Also, the delay in waking in the ringer group was significantly higher than ringer's lactate group. <br /><strong>Conclusion:</strong> According to the findings of this study, it seems that in elective surgery, the replacement of crystalloids ringer and ringer's lactate, there is a significant difference in PH and postoperative complications following the use of these serums.
