Comparison of videolaryngoscope-guided versus standard digital insertion techniques of the ProSeal™ laryngeal mask airway: a prospective randomized study.

Background: This study were designed to investigate the usefulness of the videolaryngoscope-guided insertion technique compared with the standard digital technique for the insertion success rate and insertion conditions of the Proseal™ laryngeal mask airway (PLMA).

Methods: Prospective, one hundred and nineteen patients (ASA I-II, aged 18-65 yr) were randomly divided for PLMA insertion using the videolaryngoscope-guided technique or the standard digital technique. The PLMA was inserted according to the manufacturer's instructions in the standard digital technique group.

Comparison of hemodynamic responses and QTc intervals to tracheal intubation with the McGRATH MAC videolaryngoscope and the Macintosh direct laryngoscope in elderly patients.

Our hypothesis was that intubations with the McGRATH MAC videolaryngoscope in elderly patients would produce less hemodynamic responses and ECG changes than the Macintosh direct laryngoscope. The patients were divided into two groups: patients who were intubated using the McGRATH MAC (Group V, n = 45) and patients who were intubated using the Macintosh direct laryngoscope (Group L, n = 45). Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), heart rate (HR) were recorded before induction with anesthesia (baseline), immediately after induction and at 1 min, 3 min, and 5 min after intubation, with simultaneous ECG.

The Effects of Remifentanil on Hemodynamic Response Attenuation After Electroconvulsive Therapy Under Sevoflurane Anesthesia.

Purpose: We evaluated the effects of a single loading dose of remifentanil (1 μg/kg) administered as an adjunct to sevoflurane, on the duration of seizure activity, recovery times, and hemodynamic profiles, during electroconvulsive therapy.

Methods: The patients were randomly allocated to receive sevoflurane-saline (Group SS) or sevoflurane-remifentanil (Group SR). Sevoflurane (8%) was initiated for anesthesia induction in both groups until loss of consciousness was achieved.

Purpose: We aimed to evaluate the effects of preoperative pulmonary hypertension (PH) on early and long term results in patients undergoing coronary bypass surgery and the effects of coronary bypass surgery on PH.

Methods: Among 2325 patients who underwent elective isolated coronary artery bypass surgery between March 2003 and March 2012, 287 patients with high preoperative pulmonary arterial pressure (PAP) ≥30 mmHg were examined. Patients' data were obtained by retrospective examination of our clinic's database.

Effect of the Addition of Ketamine to Sevoflurane Anesthesia on Seizure Duration in Electroconvulsive Therapy.

Objectives: We evaluated the effects of a subanesthetic dose of ketamine, which was administered as an adjunct to sevoflurane, on duration of seizure activity, hemodynamic profile, and recovery times during electroconvulsive therapy in patients with major depression.

Methods: Patients were randomly allocated to a group receiving either sevoflurane-ketamine (group SK) or sevoflurane-saline (group SS). Sevoflurane was initiated in both groups at 8% for anesthesia induction until loss of consciousness was achieved, at which point it was discontinued.

Anesthesia Management in Aortic Dissection in Patients Undergoing Kidney Transplant.

Kidney transplant is a last resort to increase the life expectancy and quality of life in patients with renal failure. Aortic dissection is a disease that requires emergency intervention; it is characterized by sudden life-threatening back or abdominal pain. In the case described, constant chest pain that increased with respiration was present on examination of a 28-year-old man (85 kg, 173 cm) who presented at our emergency department complaining of severe back pain.

Purpose: To evaluate the effect of sevoflurane or ketamine on the corrected QT (QTc) interval and the interval from the peak to the end of the T wave (Tp-e) during electroconvulsive therapy (ECT) in patients with major depression.

Methods: This prospective, randomized, double-blinded study included 24 patients that were randomly allocated to receive sevoflurane (group S) or ketamine (group K) for ECT session. Group S patients received 8 % sevoflurane for anesthesia induction, which was maintained at 2-4 % until delivery of the electrical stimulus.

Context: Patients with dementia have a lower bispectral index score (BIS) when awake than age-matched healthy controls.

Objectives: The primary aim was to compare the BIS and the dose of propofol required for induction in patients suffering from cognitive impairment with that in those who had normal cognitive function. This study also evaluated the effects of cognitive impairment in the elderly on anaesthetic agent consumption during surgery and on emergence from anaesthesia.

This randomised controlled study evaluated the effects of fentanyl and dexmedetomidine on emergence characteristics of children having adenoidectomy and anaesthetised with sevoflurane. Ninety children, two to seven years of age and ASA physical status I, were studied. Children were randomly assigned to one of three groups of 30 children, with the study intervention injection given intravenously after intubation.

Ethical problems observed by student nurses.

This descriptive study was conducted to determine nursing students' observation of ethical problems encountered in their clinical practice. Data were collected through a questionnaire from 153 volunteer nursing students at a university-based nursing school in Ankara, Turkey. The students reported that some patients are either physically or psychologically mistreated by doctors and nurses; they were not given appropriate information; they were subjected to discrimination according to their socio-economic situation; and their privacy was ignored.

The aim of this study was to evaluate whether esmolol has an effect on QT interval during induction of anaesthesia using etomidate and fentanyl in patients with known coronary artery disease. Sixty patients were prospectively randomised to either a control group or the esmolol group. Esmolol was administered as a bolus 1 mg.

Remifentanil and propofol for tracheal intubation without muscle relaxant in children: the effects of ketamine.

Background And Objective: Remifentanil and propofol have been proposed for intubation without muscle relaxant to avoid the adverse effects of muscle relaxants in children. We hypothesized that the addition of ketamine to remifentanil and propofol would improve intubating conditions and provide haemodynamic stability.

Methods: We studied 88 children (3-12 years) undergoing elective surgery.

Effects of propofol or etomidate on QT interval during electroconvulsive therapy.

Background: Because patients with major depression have an altered autonomic nervous system activity, the risk of arrhythmias and sudden cardiac death may be increased. In addition, electroconvulsive therapy (ECT) may cause an acute rise in QT dispersion, which may predispose to arrhythmias. In this study, we investigated the effects of propofol or etomidate on the corrected QT (QTc) interval during ECT in patients with major depression.
