For a patient under any treatment it is very important to maintain a stable cardiovascular system (CVS) under anesthesia. The CVS can be disturbed due to many factors, and one of the factor which can later the hemodynamic system of the patient is laryngoscopy and intubation. Hence the assessment of the variations in the blood pressure (BP) and heart rate (HR) of the patient during laryngoscopy and intubation is very important. Hypertension and Tachycardia as a great disorders causing great problems. Such as cerebral hemorrhagia and myocardial infection, which are occurred during general anesthesia. Laryngoscopy and endotracheal intubation is necessary for airway management prevention of the aspiration of gastric contents. The amount of blood pressure and heart rate is measured in 1, 3, 5 after laryngoscopy and intubation. 70 patients ASA1 with the age of 16-55, undergone elective surgery and a general anesthesia were selected. Some drug pre-medication and induction were the same in rate about all patients. 35 patients are intubated orally and the rest of them nasally. The subjects were chosen among patients who did not have difficult intubation and cardiovascular disorders. Before laryngoscopy and 1, 3, 5 minutes blood pressure and HR measured. According to outcoming results, blood pressure and HR increasing after laryngoscopy in both group (Oral intubation and nasal intubation). The increase of nasotracheal intubation was more than oral one remarkably. The difference would be meaningful according to statistic point (P<0.05). According to research finding the most amount of increase in the blood pressure and HR was related to the laryngoscopy and intubation. These changes can make problems for some cardiovascular patients. So it is suggested that all anesthetists should lessen the probable complication of patients under laryngoscopy a tracheal intubation by monitoring BP and HR.

Background & Objective: Post-general anesthesia urinary retention is a common and bothering complication. In this study prediction value of IPSS for post-general anesthesia urinary retention was evaluated. Materials & Methods: This prospective study include 100 male patients over 50 years old who were candidated for nenurologic and non-nenurological elective surgery without any urology and neurologic past medial history. IPSS was calculated for each patient. The patients were followed in post operative period for urinary retention. Results: 1.8% of patients who had mild symptoms (IPSS=0-7) had urinary retention in 2nd 24 hours of post-operative period, 20% of patients who had IPSS=8-19 and 53.3% of patients with IPSS=20-53 had urinary retention at same period (P<0.05). Conclusion: IPSS can predict postoperative urinary retention in elderly male patients. If severe symptoms by IPSS was encountered the patients and health care personals must be cautioned about possibility of postoperative urinary retention and if required urologic consulation.

Background & Objective: The cuff of the endotracheal tube is securing for mechanical ventilation during anesthesia. Diffusion of N2O in the cuff results in an increase in cuff pressure. The different method was used for the control of cuff pressure, but may have difficulty and side effect. This study was to determine whether inflating the ETT cuff with air, Lidocaine 1% or N2O with O2, prevent the increase in cuff pressure during N2O anesthesia. Materials & Methods: In this randomized control trial study after obtating ethics committee 224 patients went understudy, these patients divided in 2 blocks (Sufe, Roach) and the one of the each block were randomized into 3 groups. Group, air Lidocaine 1% N2O with O2 difficult intubation and the film anesthesia with less than 30-min were excluded. All patients were similarly anesthetized and performed tracheal intubation. The pilot balloon of the endotracheal tube cuff was connected to a Japanes pressure manometer. The first pressure was measured immediately and further reading at 10-minute intervals for 70 minutes. The results were readings analyzed using T-test, paired T-test, ANOVA and the Chi-square test. A P-value of <0.05 was considered significant. Results: Cuff pressure increased gradually during anesthesia in-group air but remained stable in group’s Lidocaine and N2O with O2. The cuff pressure had significant differences between the Supa and Roach groups in all of the times during anesthesia (P<0.05). Conclusion: Inflating the ETT cuff with Lidocaine 1% or N2O/Oxygen mixtures are methods of keeping intracuff pressure stable during N2O anesthesia due to N2O diffusion the cuff tube causes increase the cuff pressure. We suggest that continuous monitoring of the UCP during anesthesia to be carried out.

Background&Objective: Sellick’s maneuver is a routinely used technique for the prevention of pulmonary aspiration of gastric contents during anesthesia. The rationale for the application of cricoid pressure necessitates that it is applied at the loss of consciousness during rapid sequence induction. Cricoid pressure therefore, may be fully applied at a level of anesthesia where awareness, and possibly recall, of the maneuver occurs. Materials&Methods: This study was setup to determine the frequency of awareness and recall Sellick's maneuver following 100 patients (ASA I, II) who candidates for lower extremity surgery were randomly enrolled in this prospective study. After induction of anesthesia and application of cricoid pressure, symptoms of awareness and recall were recorded. Data were analyzed by SPSS software and Spearman correlation. Results: The frequency of awareness and recall were 45% and 16% respectively. The frequency distribution of awareness severity based on grade 1, 2 and 3 were 16%, 6% and 1% respectively. The frequency distribution of recall severity based on mild, moderate and sever were 15%, zero and 1% respectively. The correlation between awareness severity and recall severity was statistically significant (P<0.05). Conclusion: Due to high frequency of awareness and recall following Sellick's maneuver and its complications, it is advaiable to revise the procedure of this maneuver and inparticular the accurte time in its application.

Background and Objective: A common complication after general anesthesia is nausea and vomiting followed by different problems such as spasm, hypoxia and pulmonary aspiration. This complication is more common in patients with full stomach, Eye injury, head trauma, cesarean and laparoscopy. Propofol and metoclopramide are two common drugs to prevent nausea and vomiting after operation. On the other hand adding dexamethasone to the above drug, has an important effect on decreasing nausea and vomiting. In this study, the effect propofol and metoclopramide associated with dexamethasone on nausea and vomiting after operation was investigated.

Materials and Methods: In this clinical trial study, 100 patients with ASA I, II classes, aged 16-60 years with selective orthopedic surgery randomly have divided into two groups. In group one, 48 patients received metoclopramide (10mg) with dexamethasone (8mg) and in group two, 52 patients received propofol (20mg) with dexamethasone (8mg), five minutes before the end of operation. Prevalence of nausea and vomiting in both groups was considered after 4 hours and results were analyzed by Chi-Square, t-student and Fisher exact tests.

Results: The rate of nausea in group 1 and 2 was 35.4% and 11.5% respectivly (P<0.05). The rate of vomiting was 27.7% and 7.7% in group 1 and 2 respectivly (P<0.05).

Conclusion: This study showed that the antiemetic effect of propofol with dexamethasone is more effective to prevent nausea and vomiting than metoclopromide with dexamethasone.

Background and Objective: Propofol is one of the most commonly used drugs in anesthesia with the pain during an injection is a side effect of this drug. This study was conducted to compare the effect of Lidocaine, Magnesium Sulfate, and Ketamine on reducing pain caused by intravenous injection of Propofol in patients Undergoing surgery.
Methods: In this double-blind randomized clinical trial study, 80 patients aged 18 to 65 years were randomly blocked and assigned into four groups including Lidocaine, Ketamine, Magnesium Sulfate and Normal Saline. The pain was measured with the Ambesh Score. Hemodynamic changes of patients were evaluated in 1, 3, and 5 minutes.
Results: The patients in Lidocaine, Ketamine, and Magnesium Sulfate groups with 75%, 70%, and 55%, respectively, did not feel pain after Propofol injection compared to Normal Saline group (25%) (P<0.05). The mean time trend of Systolic and diastolic blood pressure and mean arterial blood pressure between the studied groups were significant (P<0.05).
Conclusion: The use of Lidocaine or Ketamine during Propofol injection can be effective in reducing pain during injection in patients undergo surgery.
