The predictive value of electrocardiographic polarization parameters on appropriate ICD shock in primary prevention heart failure patients.

Object: The effect of frontal QRS-T angle, Tp-e and Tp-e/QT ratio on cardiac events have been shown in many studies. In this study, we aimed to determine the prognostic value of frontal QRS-T angle, TPe and Tp-e/QT ratio on ICD shock in patients who had ICD (Implantable Cardioverter Defibrillator) implanted due to heart failure with reduced ejection fraction (HFrEF).

Material And Method: 158 patients with HFrEF who had previous ICD implantation were retrospectively analyzed.

Evaluation of left atrial and left ventricular functions in patients with Wolff-Parkinson-White syndrome before and after radiofrequency catheter ablation using three-dimensional speckle tracking echocardiography.

Background: Wolff-Parkinson-White (WPW) syndrome is one of the most common congenital cardiac abnormalities among ventricular pre-excitation syndromes. Radiofrequency catheter ablation (RFCA) treatment of accessory pathways (APs) in WPW patients is an established curative therapy restoring normal atrioventricular conduction. We have not encountered any studies evaluating both the LA and LV functions of these patients before and after RFCA with three dimensional-speckle tracking echocardiography (3D-speckle tracking echocardiography (STE)).

An Effective Novel Index for Predicting the Recurrence of Atrial Fibrillation Ablation: P Wave Duration-to-Amplitude Ratio.

Objective: Atrial fibrillation is the most common arrhythmia observed in the clinical practice. Pulmonary vein isolation is a well established treatment option for atrial fibrillation but is limited by recurrence. Previous studies have demonstrated that abnormal P wave indices were associated with adverse atrial remodeling and its role in predicting atrial fibrillation recurrence.

Efficacy of Intravenous Ibuprofen and Intravenous Paracetamol in Multimodal Pain Management of Postoperative Pain After Percutaneous Nephrolithotomy.

Purpose: Many different techniques, including multimodal analgesia, have been used for the management of postoperative pain after Percutaneous nephrolithotomy (PCNL). Ketorolac, intravenous (IV) paracetamol, rofecoxib, and IV ibuprofen have been used as a part of a multimodal analgesic approach in different surgical procedures. However, the efficacy of IV ibuprofen has not been well elucidated in adult patients undergoing elective PCNL.

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.

The effect of placement of a support under the shoulders on laryngeal visualization with a C-MAC Miller Video Laryngoscope in children younger than 2 years of age.

Background: We aimed to evaluate glottis visualization and time to intubation in children younger than 2 years of age during laryngoscopy performed with a C-MAC Miller Video Laryngoscope in a position determined by placing a folded towel under the shoulders to align the oral-pharyngeal and laryngeal axes in the horizontal plane.

Methods: Ninety-six children younger than 2 years of age, who were classified by the American Society of Anesthesiologists as having a physical status I or II and who were scheduled for elective surgery necessitating endotracheal intubation under general anesthesia, were included in the study. All patients were intubated with a C-MAC Miller Video Laryngoscope.

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.

Comparison of intravenous ibuprofen and acetaminophen for postoperative multimodal pain management in bariatric surgery: A randomized controlled trial.

Study Objective: Multimodal analgesic strategies are recommended to decrease opioid requirements and opioid-induced respiratory complications in patients undergoing laparoscopic bariatric surgery. Recent studies have demonstrated that intravenous ibuprofen decreases opioid consumption compared with placebo. The primary aim of this study was to compare the effect of intravenous ibuprofen and intravenous acetaminophen on opioid consumption.

Changes in Melatonin, Cortisol, and Body Temperature, and the Relationship Between Endogenous Melatonin Levels and Analgesia Consumption in Patients Undergoing Bariatric Surgery.

Background: Melatonin has analgesic, anti-inflammatory, sedative, and anxiolytic properties. However, the relationship between endogenous melatonin levels and postoperative analgesic requirements has not been well elucidated in patients undergoing bariatric surgery. We studied endogenous melatonin levels, cortisol levels, body temperatures, and the relationship between the level of endogenous melatonin and postoperative morphine consumption.

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.

Ultrasound-guided transversus abdominis plane block for postoperative analgesia in living liver donors: A prospective, randomized, double-blinded clinical trial.

Background: Transversus abdominis plane (TAP) block is a peripheral nerve block that reduces postoperative pain, nausea, vomiting and the need for postoperative opioids following various types of abdominal surgery. The primary aim of the present study was to evaluate the effects of TAP block on postoperative analgesia and opioid consumption in living liver donors in whom a right "J" abdominal incision was used.

Methods: This prospective, double-blinded, randomized controlled study was conducted with 50 living liver donors, aged 18-65years, who were scheduled to undergo right hepatectomy.

Effect of transversus abdominis plane block in combination with general anesthesia on perioperative opioid consumption, hemodynamics, and recovery in living liver donors: The prospective, double-blinded, randomized study.

Background: Transversus abdominis plane (TAP) block provides effective postoperative analgesia after abdominal surgeries. It can be also a useful strategy to reduce perioperative opioid consumption, support intraoperative hemodynamic stability, and promote early recovery from anesthesia. The aim of this prospective randomized double-blind study was to assess the effect of subcostal TAP blocks on perioperative opioid consumption, hemodynamic, and recovery time in living liver donors.

Patient-controlled Intermittent Epidural Bolus Versus Epidural Infusion for Posterior Spinal Fusion After Adolescent Idiopathic Scoliosis: Prospective, Randomized, Double-blinded Study.

Study Design: A prospective, randomized, double-blinded study.

Summary Of Background Data: Epidural analgesia is an accepted efficacious and safe procedure for postoperative pain management in scoliosis surgery.

Perioperative Management of Severe Hypertension during Laparoscopic Surgery for Pheochromocytoma.

Phaeochromocytoma is a catecholamine-secreting vascular tumour that is derived from chromaffin cell. Lethal cardiovascular complications, such as serious hypertension, myocardial infarction and aortic dissection, may occur because of uncontrolled catecholamine release. Each stage of anaesthesia management has vital importance because of this destructive catecholamine secretion that may occur during induction, perioperative stage and surgical manipulation.

Blood glucose regulation during living-donor liver transplant surgery.

Objectives: The goal of this study was to compare the effects of 2 different regimens on blood glucose levels of living-donor liver transplant.

Materials And Methods: The study participants were randomly allocated to the dextrose in water plus insulin infusion group (group 1, n = 60) or the dextrose in water infusion group (group 2, n = 60) using a sealed envelope technique. Blood glucose levels were measured 3 times during each phase.

Comparison of antioxidant effects of isoflurane and propofol in patients undergoing donor hepatectomy.

Background: The safety of healthy volunteer donors is one of the most important issues in living-donor liver transplantation. Use of the Pringle maneuver during donor hepatectomy can result in liver ischemia-reperfusion (IR) injury. The objective of this study was to examine the effects of isoflurane and propofol on IR injury caused by the Pringle maneuver during donor hepatectomy.

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.

Cancer antigen 125 levels and increased risk of new-onset atrial fibrillation.

Objective: Elevated cancer antigen 125 (CA-125) levels are associated with cardiopulmonary disorders such as acute and chronic heart failure (HF), coronary artery disease, chronic obstructive pulmonary disease, and atrial fibrillation (AF). The development of atrial fibrillation (AF) is related to morbidity and mortality in patients with HF: therefore, it is important to identify patients with increased risk for development of AF. We investigated whether plasma CA-125 levels in patients with hospitalized systolic HF could predict the development of AF.

Anaesthetic Management in Obstructive Sleep Apnoea Syndrome for Adenotonsillectomy.

The anaesthetic management of adenotonsillectomy in children with obstructive sleep apnoea syndrome is characteristic due to respiratory and cardiac side effects. A detailed physical examination in the preoperative period should be performed, including children's respiratory and cardiac systems. If they have an active infection, surgery should be postponed until the end of medical treatment.
