Jahangiry B,Movafegh A
Tehran University Medical Journal , 1998,
Abstract: Effects of preanaesthetic medication are as follows: 1) Promotion of mental and emotional relaxation. 2) Inhibition of nausea and vomiting after surgery. 3) Stability of haemodynamic response. We performed 105 patients, randomized, single blind clinical trial, preanaesthetic drugs, promethazine and droperidol: A comparison of haemodynamic response for patients in elective surgery at imam hospital. 105 patients were divided in three groups. Promethazine group 35 patients, dropetidol group 35 patients and normal saline group 35 patients. Systolic and diastolic blood pressure and pulse rate were recorded before and after intramuscular injection. Patients of promethazine and droperidol groups responded with decreasing in blood pressure and pulse rat lower than normal saline. But haemodynamic response did not show any difference between two groups (promethazine and droperidol).

Tehran University Medical Journal , 2005,
Abstract: Background: The combined MMCOA deficiency and Hemocystinuria results from defect in cb1c & cb1d & cb1F genome. Until now only 100 cases of this disease has been reported. Most of them with cb1c deficiency. Due to this enzymatic defect, mild to moderate retention of Hemocystin (MMA) and their precursors in the body fluids (blood and urine) ensues. Although, acidemia, Hypoglycemia & megaloblastic anemia are common but hyperamonemia and hyperglycemia were not reported in these patients. Our case is a 3 years old girl with known MMCOA deficiency and Hemocystinuria who needed G.A for partial resection of the mandible because of osteomilitis. Materials and Methods: In this report we explain the preoperative preparation of the patient, induction and maintenance of Anesthesia, and discuss the biochemical, lab results during & after surgery. Results & Conclusion: Due to our result, the urine and blood hemocystin & MMCOA were not increased. This case is interesting because no theoretical or practical report on the G.A of these patients exists.

Tehran University Medical Journal , 2005,
Abstract: Background: One of the disturbing complications of propofol is pain on venous injection. Some investigators had reported that corticosteroids effectively induce and prolong the duration of local anesthetics. The aim of this study was to assess and comparing the efficacy of propofol pretreatment with dexamethasone in prevalence and severity of its pain on injection. Materials and Methods: In a randomized, double-blinded, placebo-controlled prospective study, 90ASA I and II, 20 to 60 years-old patients scheduled for elective surgery under general anesthesia were enrolled. In all patients, one of the veins of both hands was catheterized with a 20 G catheter. Then randomly, and simultaneously 2 ml dexamethasone (8 mg) was injected to one of them and 2 ml of normal saline was injected to other. After 30 seconds, 2 ml propofol (20 mg) was injected to both hands, at the same time in 30 seconds. Pain intensity was measured using VAS system. Results: The age mean was 32.87±5.61. Twenty nine patients were male (32.2%). The mean of pain during propofol injection was significantly lower in dexamethasone group than normal saline group (1.61 vs.4.21 respectively, p 0.05). Conclusion: Intravenous administration of 8 mg dexamethasone before propofol IV injection significantly decreases the pain on injection of propofol.

Abstract: Subcutaneous emphysema is a rare complication of postoperative nausea and vomiting and can lead to airway compromise. We describe a case of delayed, severe subcutaneous emphysema after postoperative vomiting which fortunately did not lead to airway compromise and eliminated with conservative management. Rough and difficult laryngoscopy and intubation, presence of clots and bloody discharge after extubation, beginning of subcutaneous emphysema in the neck spreading caudally to the chest and fibroptic bronchoscopic findings all confirmed tracheal trauma as the cause. In this case the late onset of the subcutaneous emphysema, good response to conservative treatment and spontaneous resolution is considerable.

Tehran University Medical Journal , 2007,
Abstract: Background: Both hypoxia and hypocapnia can cause broncho-constriction in humans, and this could have a bearing on performance at high altitude. The objective of this study was to examine how pulmonary ventilatory function during high-altitude trekking. Methods: This study was a before and after study on spirometric parameters at Base line (1150 m above sea level), and after ascending at 4150 m above sea level. This study was performed in summer 2004 at Cialan Mountain in Iran. Fifty six healthy male University student volunteers were enrolled in the study. Respiratory function was assessed in participants before ascending at baseline (1150 meter) and after ascending at 4150 meter in Cialan Mount with a Spirolab II. Spirometric parameters changes were compared using paired t-test statistical analysis computations were performed by spss 11.5 and p≤0.05 was considered significant. Results: The mean age and body mass lindex of our subjects were 22.9±5.3 years and 21.5±2.5, respectively. Forced vital capacity (FVC) was significantly decreased with increasing altitude from baseline level (P0.05). FVC fell by the average of 7.1% at 4150m (2.4% per 1000m increased altitude) in comparison to 1150m. Conclusion: The changes in some pulmonary ventilatory parameters were proportional to the magnitude of change in altitude during a high-altitude trek.

Movafegh A,Mir Eskandari M,Eghtesadi Araghi P
Tehran University Medical Journal , 2003,
Abstract: One of the disturbing complications of propofol is pain on injection and the incidence ranges from 28% to 90%. Metoclopromide is commonly used as an anti emetic drug. Some investigators reported that this drug could reduce the pain on injection of propofol. The aim of this study was to assess and comparison of the efficacy of propofol pretreatment with metoclopromide in incidence and severity of its pain on injection."nMaterials and Methods: In a randomized, prospective, double-blinded, placebo-controlled trail, 150 patients 18 to 40 yr old were randomly allocated in one three groups. C group (2ml of normal saline), L group (40mg lidocaine in 2ml), M group (l0mg metoclopromide in 2ml). Immediately after injection of study or placebo drugs, 10 mg of propofol with injection rate of 0.5 ml/s (In 4 Seconds) were injected in to the same vein that was inserted to the most prominent dorsal hand vein. Pain severity was measured using Visual Analogue Pain Scale that were educated to the patients before the trail (0 for no pain and 100 for the most aggressive pain in life) and values other than zero was encountered pain appearance. Patients with signs of sedation were excluded."nResults: There was no statistically significant difference between patients in three groups in number of men and women (P = 0.66), age (P = 0.29) and weight (P = 0.49). Furthermore severity (P = differences (C = 41.18, L - 25.4 and M = 13.1, P < 0.001) and patients in metoclopromide group experiences lower pain than other two groups (P < 0.001). Pain incidence in Control group was 77.1% and it was significantly reduced in lidocaine and metoclopromide group (P = 0.002), but there were no significant difference between them (P = 0.051). The 0.69) and incidence (P ~ 0.29) of pain has no significant difference between men and women. Pain severity between three groups has significant results showed that metoclopromide could significantly reduce the seventy of pain on injection of propofol more than lidocaine (opposite to diazepam), but they had no difference in pain incidence. It might lie on the different mechanisms that they produce pain. Pain on injection of diazepam is primarily attributed to propylene glycol, as a vehicle, but the pain mechanism in propofol is remaining unknown."nConclusion: Finally as regards to other useful effects of metoclopromide including postoperative nausea and vomiting and propofol induction dose reduction, especially when there is a medical condition where lidocaine is contraindicated, it may be a reasonable alternative before injection of propofol.

Abstract: Intravenous administration of dexamethasone before diazepam injection seems "0 reduce the incidence or pain on injection. We conducted a randomized. prospective, double-blind. placebocontrolled clinical trial to compare effect or dexamethasone, mctoclopramidc ami placebo in reducing the injection pain.:" total of 120 ASA class I and ll mcn aged 20-45 years that needed more than one intravenous access were enrolled in the study and were randomly allocated to one of the three groups: group 1, :2 ml intravenous normal saline and 2 1111 dexamethasone (X mgj: group 2. 2 1111 intravenous normal saline and 2 1111 mctoclopramidc l10 mg), and group 3.:2 ml intravenous dexamethasone (X mg) and 2 ml ructoclopramidc (10 mg). After 30 seconds. I ml diazepam (5 mg) was injected simultaneously into each of patients' hand veins and a maximal visual analog scale (VAS) for pain of each venous discomfort was assessed separately. In group I. the mean of VAS for pain was significantly less in dexamethasone pretreatment than saline pretreatment. In group 2. the mean of VAS for pain was significantly less in mctoclopramidc pretreatment than saline pretreatment. In group 3, the mean of VAS for pain was significantly less in dexamethasone pretreatment than mctocloprauudc pretreatment. There were no significant differences in incidence of pain between pretreatment and placebo in three groups. Dexamethasone or mctoclopramidc pretreatments arc effective in reducing the severity of pain on injection of diazepam and dexamethasone pretreatment has greater efficacy in reducing the intensity of pain.

Abstract: In the present study we conducted a randomized, prospective, double-blind, placebo-controlled clinical trial to evaluate the prolongation of lidocaine spinal anesthesia by intrathecal administration of dexamethasone. Ninety male patients scheduled for orthopedic surgery under spinal anesthesia were enrolled in the study and were randomly allocated to one of three groups and received their treatments intrathecaly; Group 1: 75 mg 5% lidocaine + 2 mL 0.9% NaCl; Group 2: 75 mg 5% lidocaine + 0.2 mg epinephrine (0.2 mL-BP) +1.8 mL 0.9% NaCl and Group 3: 75 mg 5% lidocaine + 8 mg dexamethasone (2 mL-BP). After performance of the block patients were kept in supine position and the pinprick level were kept between T6 to T8 in all patients. Block regression was estimated by pinprick every 5 min until a 4 sensory level regression from highest level. The duration of motor block was the time needed until the block returned to level 0 from level 3 on the Bromage scale. There were no significant differences in demographic data, duration of surgery, ASA classes (I/II), the maximal cephaled level and onset time of sensory and motor block among the groups. The duration of sensory block was significantly longer in the lidocaine-epinephrine and lidocaine-dexamthasone groups than the lidocaine group (respectively 85.7 and 82.1 min vs. 55.9 min for sensory block and 112.8 and 118.9 min vs. 79.2 min for motor block, p<0.001). The incidence of complications and the need for treatments were not different among groups. After one month follow up, no neurological or infectioneuos disorder was found in patients. We have shown that the addition of dexamethasone (8 mg-BP) intrathecaly to lidocaine spinal anesthesia prolongs the duration of intrathecal lidocaine sensory and motor blocks.
