Post-cesarean Delivery Analgesia Using Spinal Anesthesia: Ropivacaine-Fentanyl vs. Ropivacaine-Sufentanil.

Background: To improve the quality of intraoperative and postoperative analgesia during spinal anesthesia, intrathecal opioids are used as adjuvant drugs in combination with local anesthetics.

Objectives: This study aimed to compare the intrathecal injection of ropivacaine-fentanyl with ropivacaine-sufentanil in terms of the duration of analgesia after cesarean section (CS).

Methods: This randomized, double-blind clinical trial study was conducted on women referred to Imam Khomeini Hospital of Ahvaz City for elective CS in 2021.

Comparison of the effect of propofol and isoflurane on hemodynamic parameters and stress response hormones during Laparoscopic Cholecystectomy surgery.

Background And Aims: General anesthesia induces endocrine, immunologic, and metabolic responses. Anesthetic drugs affect endocrine system by changing the level of stress hormones and hemodynamic of the patient . The purpose of this study was to compare the effects of propofol and isoflurane on hemodynamic parameters and stress-induced hormones in laparoscopic cholecystectomy (LC) surgery.

Effect of Intra-articular Dexmedetomidine on Postoperative Pain after Knee Arthroscopic Surgery.

Background: This study aimed to prevent and control the pain after arthroscopy that leads to patient satisfaction, rehabilitation, and return to normal life as soon as possible. It is hypothesized that there is no difference between intra-articular injection of dexmedetomidine and placebo after knee arthroscopy regarding pain level.

Methods: This double-blind randomized clinical trial was conducted on 70 patients aged 18-60 years who were candidates for elective knee arthroscopic surgery with the American Society of Anesthesiologists Classification I-II.

Comparison of the Effect of Propofol and Dexmedetomidine on Hemodynamic Parameters and Stress Response Hormones During Laparoscopic Cholecystectomy Surgery.

Background: General anesthesia induces endocrine, immunologic, and metabolic responses. Anesthetic drugs affect the endocrine system by changing the level of stress hormones and hemodynamic variables of the patient.

Objectives: The purpose of this study was to compare the effects of propofol and dexmedetomidine on hemodynamic parameters and stress-induced hormones in laparoscopic cholecystectomy (LC) surgery.

Assessing the uptake and accumulation of heavy metals and particulate matter from ambient air by some tree species in Isfahan Metropolis, Iran.

The main scope of this study is to evaluate the uptake and accumulation potential of heavy metals in unwashed and washed leaves and particulate matter (PM) in leaf surfaces plus waxes of different tree species in Isfahan city. The highest mean concentrations of Cd, Cr, and Ni in unwashed and washed leaves were detected in M. nigra, Zn and Cu in P.

The Effect of Intravenous Magnesium Sulfate Versus Intravenous Sufentanil on the Duration of Analgesia and Postoperative Pain in Patients with Tibia Fracture.

Background: In the recent decades controlling postoperative pain has become a popular topic as it leads to the patients' wellbeing and improved life quality, while it reduces the costs for both patients and medical facilities.

Objectives: This study aimed at comparing intravenous magnesium sulfate versus intravenous sufentanil on the duration of analgesia and postoperative pain in patients undergoing tibia fracture surgery.

Methods: This double blind clinical trial study was performed on 70 candidates of tibia fractures between the ages of 18 and 55 years with American society of anesthesiologists (ASA) class I and II.

The effect of EDDS and citrate on the uptake of lead in hydroponically grown Matthiola flavida.

Root and shoot lead concentrations and the impact of chelating agents on these were investigated in two populations of the novel metallophyte Matthiola flavida. Plants were exposed in hydroponics to Pb(NO3)2, supplied alone, or in combination with citric acid, or EDDS. When supplied at concentrations expected to bind about 95% of the Pb in a solution containing 1-μM Pb (1000 μM citrate or 3.
