BACKGROUND We investigated the effects of a magnesium sulfate pretreatment on intubating conditions and cardiovascular responses during rapid sequence tracheal intubation (RSI) in this double-blind randomized study. METHODS Adult patients (n = 154) were randomly allocated to a rocuronium-0.6, rocuronium-0.9, or magnesium group. The magnesium group was pretreated with 50 mg/kg MgSO4, and the o...

Dolichodorus aestuarius n. sp. from an estuarine habitat near Cedar Key, Florida is described. This nematode has a stylet range of 62-76 microm in females and 60-72 mum in males. The stylet is shorter than those of all described species except D. brevistilus. The probable host plant is Juncus roemerianus.

BACKGROUND AND OBJECTIVES Anesthesiologists are responsible for airway management whenever they assume the anesthesia of a patient. In this study, we compare the hemodynamic parameters of rigid laryngoscopy and lighted stylet in patients with coronariopathies. PATIENTS AND METHODS This randomized clinical trial included 40 patients undergoing myocardial revascularization assigned into two gro...

A root-knot nematode parasitizing coffee in Paran State, Brazil, is described as Meloidogyne paranaensis n. sp. The suggested common name is Paraná coffee root-knot nematode. The perineal pattern is similar to that of M. incognita; the labial disc and medial lips of the female are fused and asymmetric and rectangular; the lateral lips are small, triangular, and fused laterally with the head reg...

OBJECTIVE: Endotracheal intubation of newborn infants is a common and potentially lifesaving procedure but a skill that trainees find difficult. Despite widespread use, no data are available on whether the use of a stylet (introducer) improves success rates. We aimed to determine whether pediatric trainees were more successful at neonatal orotracheal intubation when a stylet was used. METHODS: ...

treacher collin’s syndrome (tcs) is a rare inherited condition characterized by bilateral and symmetric abnormalities of structures within the first and second bronchial arches. patients with tcs present a serious problem to anesthetists maintaining their airway as upper airway obstruction and difficult tracheal intubation due to severe facial deformity. because of retrognathia, airway manageme...

BACKGROUND AND OBJECTIVES Epidural catheter bacteria filters are barriers in the patient-controlled analgesia/anaesthesia for preventing contamination at the epidural insertion site. The efficiency of these filters varies according to pore sizes and materials. METHOD The bacterial adhesion capability of the two filters was measured in vitro experiment. Adhesion capacities for standard Staphyl...
