Comparison of the Combined Femoral and Lateral Femoral Cutaneous Nerve Block Plus Popliteal Block with Spinal Anesthesia for Thigh Tourniquet Pain During Foot or Ankle Surgery: A Randomized Clinical Trial.

Background: A pneumatic thigh tourniquet is routinely used during lower-extremity orthopedic surgeries to provide a bloodless field. When using peripheral nerve blocks, tourniquet-related thigh pain and discomfort limit their routine use as an anesthetic method.

Objectives: The aim of the present prospective, randomized study was to compare the efficacy of combined femoral nerve/lateral femoral cutaneous nerve block technique and spinal anesthesia on intraoperative thigh tourniquet pain.

Saline vs. dextrose for local anesthetic dilution in brachial plexus block: A randomized study.

Higher sodium ions in saline diluted local anesthetic may reduce the anesthetic action of the drug as injected around the nerves. However, the impact of local anesthetic dilution agents on the quality of peripheral nerve blockades has not yet been widely investigated. This study was aimed at evaluating the impact of lidocaine dilution with normal saline vs dextrose 5% on onset time of supraclavicular approach to brachial plexus block.

Comparison of rectal indomethacin, diclofenac, and naproxen for the prevention of post endoscopic retrograde cholangiopancreatography pancreatitis.

Background And Aim: NSAIDs are commonly utilized for the prevention of post endoscopic retrograde cholangiopancreatography pancreatitis (PEP). However, not much is known about the most effective drug in preventing this complication. This study aims to clarify which drug (indomethacin, diclofenac, or naproxen) is most effective for the prevention of post endoscopic retrograde cholangiopancreatography (ERCP).

Preemptive Oral Clonidine Provides Better Sedation Than Intravenous Midazolam in Brachial Plexus Nerve Blocks.

Background: Preemptive analgesia is the blocking of pain perception afferent pathways before noxious painful stimuli. Clonidine is an alpha agonist drug that is partially selective for α-2 adrenoreceptors. Clonidine is used as anti-anxiety medication and an, analgesic, and it prolongs the duration of the block in the brachial plexus block.

Memantine in the prevention or alleviation of electroconvulsive therapy induces cognitive disorders: A placebo controlled trial.

The purpose of this study was to evaluate the effect of memantine administration on the adverse cognitive effects of electroconvulsive therapy (ECT). Forty patients diagnosed with a major depressive disorder for which ECT was indicated as a treatment for their current episode were randomly allocated to either the memantine (5mg/day) group or the placebo group. All patients underwent the same protocol for anaesthesia and ECT procedures.

Effects of propofol versus isoflurane on liver function after open thoracotomy.

Background: Anesthetic agents and type of surgery may contribute to postoperative hepatic injury. Inhalational anesthetics have been associated with hepatic dysfunction after surgery, however, propofol is expected to have a lower potential for postoperative liver injury. This prospective double-blind randomized clinical study was planned to determine whether postoperative liver function differs after anesthesia with isoflurane and total intravenous anesthesia with propofol in patients undergoing a posterolateral thoracotomy.

Co-presentation of Tapia's syndrome and pressure alopecia--A rare event after septorhinoplasty: A case report and literature review.

Tapia's syndrome and pressure alopecia (PA) are two rare but distressing complications associated with orotracheal intubation and positioning of the head during surgery. To our knowledge, simultaneous occurrence of both complications after surgery has not been previously reported. To avoid these disturbing complications, the mechanisms of the injury and the preventive measures should be recognized by anesthesiologists and surgeons.

Role of laryngeal mask airway in interventional bronchoscopy procedures for upper tracheal stenosis: case series.

Background: Bronchoscopic interventional procedures are novel means of treating airway lesions which are less invasive and well tolerated for patients with endo-luminal lesions, but managing the airway and oxygenating the patient in a field that is shared by both anesthesiologist and bronchoscopist is a major concern. Also in cases with subglottic and upper tracheal stenotic lesions an airway device placed inside the lumen interferes with the procedure and occasionally bears the hazard of ignition. Therefore, an airway device placing above the glottis with effective oxygenation is required.

Heart-lung transplantation in Iran: a case report.

We report our initial experience with a heart-lung transplant operation performed on a 12- year- old girl with Eisenmenger syndrome at Masih Daneshvari Teaching Hospital in Tehran, in 2009. We also outline the operative indications, anesthetic management, and postoperative complications of heart-lung transplantation. We hope that this issue on transplantation may provide an encouraging prospect for patients with end-stage cardiopulmonary disorders in Iran.

Acute respiratory failure as a rare complication of celiac plexus block in a patient with adenocarcinoma of the ampulla of vater.

Celiac and splanchnic plexus blocks are considered as terminal approaches for pain control in end stage pancreatic cancer. It may be done temporarily (using local anesthetics) or as a permanent act (using alcohol and/or phenol). Like every other interventional procedure, celiac plexus block has its own potential complications and hazards among them pneumothorax and ARDS are very rare.

The efficacy of a single dose of pethidine, fentanyl and morphine in treating postanesthesia shivering.
