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.

The effects of N-acetylcysteine on pulmonary functions in patients undergoing on-pump coronary artery surgery: a double blind placebo controlled study.

Objective: To investigate the effects of N-acetylcysteine (NAC) on pulmonary function tests and arterial blood gases in patients undergoing on-pump coronary artery surgery.

Patients And Methods: The effect of NAC was assessed within the scope of a prospective, single center, double-blind, placebo-controlled, parallel group study. Eighty-two patients undergoing coronary artery bypass grafting were randomized into two groups to receive either placebo (group 1, n = 40) or NAC (group 2, n=42).

Coronary Bypass Surgery in Patients with Pulmonary Hypertension: Assessment of Early and Long Term Results.

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.
