UNLABELLED Standard transesophageal echocardiography (TEE) does not allow cardiac monitoring during the induction of anesthesia because standard probes would limit the oropharyngeal space and impair mask ventilation and tracheal intubation. We hypothesized that a prototype, miniaturized TEE probe could be safely introduced transnasally in awake patients and that mask ventilation and orotracheal...

background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...

Durian leaves have been used extensively to aid in the anesthetic process various types of fish. The purpose this study was determine immotilization capacity and stress response survival Tilapia under anesthesia. RAL design (4x4) carried out with durian leaf infusion treatment at concentrations 2%, 4%, 6% 8%. fastest induction sedation times were 8% concentrations, which 12.33 minutes 13.35 min...

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension....

Purpose: To evaluate whether oral clonidine premedication affects the induction dose of propofol and awakening time from epidural and propofol anesthesia. Methods: Thirty-nine female patients (ASA I or II) were randomly allocated to receive 5 jL/g-kg" clonidine po or no clonidine 90 min before induction of anesthesia. After epidural anesthesia was achieved with lidocaine, general anesthesia was...

PURPOSE To evaluate whether oral clonidine premedication affects the induction dose of propofol and awakening time from epidural and propofol anesthesia. METHODS Thirty-nine female patients (ASA I or II) were randomly allocated to receive 5 microg x kg(-1) clonidine p.o. or no clonidine 90 min before induction of anesthesia. After epidural anesthesia was achieved with lidocaine, general anest...

in this survey, 55 patients were studied in a period of six years for having the anesthesia in the sitting position. in this position, the surgeon will had a better access to the location, whose damages have been sustained, so less damages would be given to the healthy tissues. for the patients, due to their critical general conditions, one week prior to giving anesthesia to the posterior fossa...

BACKGROUND The purpose of this study was to determine whether parental auricular acupuncture reduces parental preoperative anxiety and thus allows children to benefit from parental presence during induction of anesthesia. METHODS Mothers of children who were scheduled to undergo surgery were randomly assigned to an acupuncture intervention group (auricular press needles at relaxation, tranqui...
