The efficacy of nasal tip hold-press on venous cannulation pain in children: a prospective randomized controlled study.

Background: Venipuncture is a common and quiet unpleasant experience for pediatric patients. The pain associated with venous cannulation disturbs the children. Different methods have been used to minimize the pain.

Factors associated with extubation time in coronary artery bypass grafting patients.

Background and Objectives. Cardiovascular diseases are the leading cause of death worldwide, with coronary artery disease being the most common. With increasing numbers of patients, Coronary Artery Bypass Grafting (CABG) has become the most common operation in the world.

Post-operative quadriplegia as the initial manifestation of tumefactive multiple sclerosis.

Post-operative quadriplegia is a rarely encountered complication and not previously reported as the initial presentation of tumefactive multiple sclerosis. We present an unusual case of a patient with such manifestation and atypical lesions on brain magnetic resonance imaging. The patient was treated with methyl prednisolone pulse therapy and showed a dramatic response.

Comparison of lidocaine, lidocaine-morphine, lidocaine-tramadol or bupivacaine for neural blockade of the brachial plexus in fat-tailed lambs.

Objective: To evaluate the onset time and duration of action of lidocaine, lidocaine-morphine, lidocaine-tramadol or bupivacaine for a neural blockade of the brachial plexus in fat-tailed lambs.

Study Design: Prospective, randomized, crossover, experimental study.

Animals: Seven healthy female fat-tailed Ghezel lambs weighing 27.

A model for decision making for intensive care unit admission in source limited hospitals.

Background: Demand for ICU beds is exceeding its supply. Since the sources are limited in some centers, it is necessary to design a model to identify the patients who benefit more from ICU beds.

Objectives: The present study aimed to develop a model to prioritize adult patients according to their clinical indications by a three rounded Delphi method study.

Molecular diagnosis of nasopharyngeal carcinoma using detection of Epstein-Barr virus latent membrane protein-1 gene in cervical metastatic lymph nodes.

Background: Cervical lymphadenopathy could be a manifestation of occult nasopharyngeal carcinoma (NPC). Epstein-Barr virus (EBV) is frequently detected in NPC, and its malignant transformation is associated through the action of the oncoprotein latent membrane protein-1 (LMP-1).

Purpose: The aim of this study was to investigate whether a primary nasopharyngeal origin could be localized by detection of EBV LMP-1 gene in cervical metastatic lymph nodes.

Analgesia for retrobulbar block--comparison of remifentanil, alfentanil and fentanyl.

Background: The injection of retrobulbar block is associated with significant pain and discomfort. Therefore a short-acting IV analgesic before retrobulbar injection has been advocated.

Objective: To compare remifentanil, alfentanil and fentanyl in providing analgesia for retrobulbar block injection.

Succinylcholine-induced masseter muscle rigidity during bronchoscopic removal of a tracheal foreign body.

Masseter muscle rigidity during general anesthesia is considered an early warning sign of a possible episode of malignant hyperthermia. The decision whether to continue or discontinue the procedure depends on the urgency of the surgery and severity of masseter muscle rigidity. Here, we describe a case of severe masseter muscle rigidity (jaw of steel) after succinylcholine (Sch) administration during general anesthetic management for rigid bronchoscopic removal of a tracheal foreign body.
