Comparison of the effect of different doses of phenylephrine infusion on the prevention of hypotension in the elderly under spinal anaesthesia in orthopaedic surgery.

Background: Considering the vasopressor drug categories and doses that can be used for elderly patients following hypotension are few, the present trial aimed to compare the effect of different doses of phenylephrine infusion on the prevention of hypotension in elderly patients undergoing orthopaedic lower extremities surgery.

Methods: This randomised, double-blind prospective clinical trial was conducted by including 60 elderly patients older than 60 years and classified as American Society of Anesthesiology class I and II who were candidates for femur fracture fixation surgery. White and black cards randomly allocated patients to: group A (25µg/kg/h phenylephrine) or group B (35µg/kg/h phenylephrine).

Investigating the Effect of Dexmedetomidine in Controlling Postoperative Emergence Agitation in Children under Sevoflurane Anesthesia.

Introduction: Emergence agitation (EA) is one of the common problems during recovery from general anesthesia, especially in children. In this study, we investigated the effect of dexmedetomidine on the control of agitation after anesthesia with sevoflurane in children.

Method: This randomized control-placebo, double-blind prospective clinical trial was conducted on seventy-six children between 2 and 7 years with ASA (American Society of Anesthesiologists) class I who were candidates for elective adenoidectomy surgery and tonsillectomy.

Short-term outcomes after surgical versus trans catheter closure of atrial septal defects; a study from Iran.

Objectives: Atrial Septal Defect (ASD) accounts for 10% of congenital cardiac defects. The purpose of this retrospective study was to compare the short-term outcomes of surgical versus trans catheter closure of secundum atrial septal defect.

Methods: This is a single-center retrospective cohort study in patients who had surgical or trans catheter ASD closure.

Anesthetic Management of an Infant Presenting with an Intrapericardial Tumor: A Case Report.

Intrapericardial teratomas are rare primary cardiac tumors. These tumors, albeit benign in essence, can be fatal if they exert pressure on the cardiovascular and/or respiratory system. We describe a 34-day-old infant, who needed emergent surgery due to cardiovascular structure compromise.

Comparison of the effects of pretreatment intravenous fentanyl or intravenous lidocaine on suppression of fentanyl-induced cough in children: a randomized, double-blind, controlled clinical trial.

Background And Aim: The injection of fentanyl usually causes coughing during induction of anesthesia. Based on a few studies about effects of lidocaine and the fact there is no study concerning the effect of fentanyl on fentanyl-induced cough in pediatric patients, the aim of this study was to compare the effectiveness of low dose of fentanyl with lidocaine in prevention of fentanyl-induced cough in children.

Methods: This randomized double-blind controlled clinical trial study was conducted at Motahari Hospital between February and August 2017 in Urmia (Iran).

Comparing prophylactic effect of phenylephrine and ephedrine on hypotension during spinal anesthesia for hip fracture surgery.

Background: Spinal anesthesia is an accepted technique in hip fracture surgery and prevention of this complication by sympathomimetic agents is of potential clinical significance. The aim of this study is to compare the effect of prophylactic phenylephrine versus ephedrine in the prevention of hypotension during spinal anesthesia in hip fracture surgery.

Materials And Methods: Ninety-two patients undergoing hip fracture surgery with the American Society of Anesthesiologists I and II were randomized to receive prophylaxis with ephedrine or phenylephrine immediately before the spinal anesthesia.
