  Background & Objective s: Poisoning is one of the most common causes that referred to the Emergence and one of the most important Medicine immediacy. Correct and immediate diagnosis and accommodative treatment can be life saving. Knowing the overall pattern of poisoning in any geographical area would help to better manage and treat the victims.

  Methods : In a cross sectional descriptive study, the required information was collected from the records of patients showing drugs and chemical poisoning who referred to Imam Khomeini hospital Collected data was statistically analyzed using SPSS software.

  Results : Out of 2852 case of poisoning, 106 people passed away due to severe complication. Of these 56.8% were men and 43.2% were women. The majority of cases (76.8%) were from urban areas. Suicide was the main cause of poisoning (66.53%). Accidental poisoning was recorded for 5.01% of cases. In 28.45% of cases, the cause of poisoning was not identified. The age group 21-30 years made the highest number of cases (52.3%). Tramadol, Benzodiazepines and Aceteminophen were the most poisons used respectively. Benzodiazeine was the most taken drug is in suicide (19.97%).

  Conclusion : Results showed that poisoning with Tramadol and Benzodiazepines is high in Ardabil Province. Opioids, Aluminum Phosphide and Organophosphores are the main causative of death in poisoned victims in the province of Ardabil.

Background & objectives: Endoscopy is an invasive and painful procedure. The use of sedatives, especially in children, is expanding. The aim of this study was to compare the sedative effects of ketofol and the combination of midazolam-ketamine in upper endoscopy in children aged 1 to 14 years who referred to Taleghani Hospital in Gorgan.
Methods: In this study, 55 children entered the study 1 to 14 years after obtaining parental consent. They were then divided into two groups, ketamine-propofol (KP) and ketamine-midazolam (KM), by simple randomization. At all stages of the work, patients underwent cardiac and respiratory monitoring. All hemodynamic parameters and ramsy sedation score (RSS) were recorded for all participants in the 5 time periods before, during and after endoscopy. ANOVA test and bonferroni tracking test were used in spss software to analyze and compare data.
Results: 54.5% were male patients. The ANOVA test showed that the scores of the two groups at the time of the study had a statistically significant difference (p=0.02). In the KM group, the mean blood pressure and heart rate of patients increased at all times compared to before the intervention (p=0.005). Blood pressure in the KP group had a steady trend over time (p<0.001).
Conclusion: There was a statistically significant difference between the scores of the two groups and the group (KM) had higher scores, but the use of two drug regimens Propofol-Ketamine and Ketamine-Midazolam caused a good sedation in pediatric endoscopy. The propofol-ketamine compound resulted in greater hemodynamic stability in cardiovascular parameters during and after endoscopy
