Evaluating Factors Affecting the Time Interval Between Propofol Injection and Induction of Electro-convulsion and Relationship Between These Factors and Duration of Convulsion.

Background: Current evidence on the effect of anesthetic-ECT time interval (AETI) is controversial. This study aimed to investigate the factors affecting the time interval between propofol injection and electro-convulsion induction and the relationship between these factors and the duration of convulsion.

Methods: In this study, 102 patients (616 sessions of ECT) were studied.

Effect of Intervenous Magnesium Sulfate on Decreasing Opioid Requirement after Surgery of the Lower Limb Fracture by Spinal Anesthesia.

Background: Magnesium is the calcium natural physiological antagonist; it also antagonizes N-Methyl-D-aspartate receptors, therefore, providing antinociceptive properties. The reason for effective role of treatment with magnesium on decreasing opioid usage, less dissatisfaction, and good sleep quality is proposed theoretically yet. This study aimed to evaluate the effect of magnesium sulfate on decreasing opioids requirement after surgery of the lower limbs fracture by spinal anesthesia.

Delayed diagnosis of bronchial transection following blunt chest trauma.

Diagnosis of blunt tracheobronchial injuries can be challenging. These injuries may appear within months or years following the initial trauma. In general, diagnosis and treatment of delayed presentation of tracheobronchial injuries are uncommon.

THE EFFECTS OF INTRATHECAL NEOSTIGMINE ADDED TO BUPIVACAINE ON POSTOPERATIVE ANALGESIC REQUIREMENT IN PATIENTS UNDERGOING LOWER LIMB ORTHOPEDIC SURGERY.

Background: Several additives have been suggested to enhance analgesic effect of local anesthetic agents to decrease the adverse effects of them and increase the degree of satisfaction. We designed this randomized double-blind controlled study to evaluate the analgesic efficacy of the neostigmine added to bupivacaine using spinal anesthesia in patients undergoing lower limb orthopedic surgery.

Methods: Sixty patients 18-80 yr old American Society of Anesthesiologists (ASA) physical status I or II, scheduled for femur surgery under spinal anesthesia, were recruited in a prospective, double-blinded, randomized way.

Efficacy of the New Perilaryngeal Airway (CobraPLA™) Versus the Laryngeal Mask Airway (LMA™) to Improve Oropharyngeal Leak Pressure in Obese and Overweight Patients.

Background: This study aimed to evaluate the applicability of Cobra perilaryngeal airway (Cobra PLA™) for obese patients under general anesthesia and also to compare the results with those of classic laryngeal mask airway (LMA™).

Materials And Methods: Seventy-three overweight and obese patients were included in this study. The patients were randomly assigned to LMA™ or Cobra PLA™ groups.

Comparison of complications in percutaneous dilatational tracheostomy versus surgical tracheostomy.

Background: Tracheostomy facilitates respiratory care and the process of weaning from mechanical ventilatory support.

Aims: To compare the complications found in percutaneous dilatational tracheostomy (PDT) and surgical tracheostomy (ST) techniques.

Methods: This was a prospective randomized study to evaluate the complications of PDT and ST procedures in patients admitted to ICU unit of a teaching hospital during 2008 to 2011.

The postoperative analgesic effect of morphine and paracetamol in the patients undergoing laparotomy, using PCA method.

Objective: postoperative pain increases the activity of the sympathetic system, causes hypermetabolic conditions, retains salt and water, increases glucose, fatty acid lactate and oxygen consumption, weakens the immunity system which delays wound healing. Our object was comparison of the analgesic effect of morphine and paracetamol in the patients undergoing laparotomy, using PCA method.

Method: Seventy patients who had undergone laparotomy were studied using double blind randomized clinical trial (35 patients received morphine and 35 paracetamol) in the Shahid Rajaee Center and Velayat Hospital (Qazvin, Iran).

Obvious and hidden anxiety and the related factors in operating room nurses employed in general hospital, Qazvin, Iran: a cross-sectional study.

Background: Health promotion and security of manpower in a society is one of the pillars to progress a society. Anxiety, is the most common psychological disorder in societies and occupations like nursing' anesthesia technicians and operation room technicians. The aim of this study was to investigate prevalence of anxiety, and its severity in Iranian nurses working in operation room.

The effect of combined ephedrine and lidocaine pretreatment on pain and hemodynamic changes due to propofol injection.

Objectives: Injection pain and hypotension are two main adverse effects of propofol that discourage uniform acceptation. The aim of this study was to compare the effect of ephedrine-lidocaine combination with lidocaine and ephedrine alone on injection pain and hemodynamic changes caused by propofol injection.

Methods: One hundred and sixty five patients were randomly allocated to five groups to receive either lidocaine 0.
