Abstract
Introduction: One of the major goals of nursing in trauma patients is clearing the airway. Therefore, this study aimed to compare the side effects of suction and nelaton catheter in patients with brain trauma.
Methods: This study is a randomized clinical trial consisting of 80 patients admitted to intensive care unit of Shahid Rahnemun hospital in Yazd. Underlying variables and suction side effects were evaluated in both suction and nelaton groups. Finally, descriptive and inferential statistical analyses were performed using SPSS Ver 16 such as Chi-square and T-test.
Results: The nelaton reduced the patients’ need to suction (P-Value for third and fourth days was respectively 0. 003 and 0. 004). After total suction with nelaton catheter, O2SAT decreased for the patients (P-Value of first day=0. 06, second day=0. 004, third day=0.002, fourth day =0. 001). Comparing O2SAT between these two types of catheter, a significant difference was observed on the fourth day(P-Value = 0. 002). The mean heart rate increased in both groups after suctioning(P-Value = 0. 0001), though no difference was found in heart rate between the two groups (P-Value of first day=0. 37, the second day=0. 13,the third day=0. 57, fourth day=0. 09). The difference between the two groups in regard with frequency of bleeding chips after suctioning proved to be significant from the third day of the study. In other words, patients in suction catheter were reported to have more bleeding chips. (P-Value of first day =0. 9, second day=0. 14, third day=0. 001, fourth day=0. 001). No significant difference was found with respect to infection (P-Value = 0. 8).
Conclusion: The study findings revealed that applying catheter nelaton can reduce the injury and bleeding to the patient's trachea to a significant percentage and can lead to less O2SAT fall.

Abstract
Introdution: Acute renal failure is a common complication in the brain injury patients. Released adenosine in injury can reduce renal glomerular filtration. Aminophylline is an inhibitor of releasing adenosine. So, this study aimed to evaluate the effect of intravenous aminophylline in renal function of brain-injured patients with acute renal failure admitted to the intensive care unit.
Methods: In this double-blind randomized controlled trial, 50 brain-injured patients with acute renal failure in the intensive care unit were divided randomly into two intervention and placebo groups. They were randomly received 0.2 mg/kg/h intravenous aminophylline or 0.2 mg/kg/h placebo (normal saline). Urine output and serum BUN and Cr were measured at 24 hours before and after the administration of aminophylline or placebo. Data were analyzed through SPSS version 22 software and using Chi-square test, independent t-test, Mann-Whitney as well as Wilcoxon tests.
Results: There was a significant difference between urine output and serum BUN and Cr at 24 hours after the study in both groups (P< 0.001). In the intervention group, there was a significant difference between urine output and serum BUN and Cr before and after the intervention (P< 0.001) and in the control group, there was no significant difference between the mean of urine output and Cr (p=0/06) and serum BUN (p=0/08) before and after the study.
Conclusion: Aminophylline can increase urine output and decrease serum BUN and Cr and improve renal function in the brain-injured patients with acute renal failure.
