Maintenance of balance between airway pressure and intracranial pressure in a patient with tracheal stenosis undergoing craniotomy: a case report.

Background And Objectives: Tracheal stenosis is a rare but a life-threatening condition and anesthesia of a patient with tracheal stenosis is challenging for anesthesiologists. Maintaining stable hemodynamics and ventilation parameters are important issues in neuroanesthesia. Any increase in airway peak pressure and ETCO will result in increase in intracranial pressure which must be avoided during craniotomies.

The airway device preference may affect the overlapping of the common carotid artery by the internal jugular vein.

Background: Anatomical variation in the internal jugular vein (IJV), as well as its small size, tendency to collapse, and proximity to the common carotid artery (CCA) makes central venous cannulation via the IJV a technically challenging procedure, especially in pediatric patients.

Aim: We evaluated the effects of laryngeal mask airway insertion and endotracheal intubation (ETT) on the anatomical relationship between the IJV and the CCA in neutral and 40° head away positions.

Method: After parental consent 92 patients with ASA physical status I-II, aged 0-17, undergoing elective urological surgery were enrolled and divided into two groups according to the airway management device used for anesthesia: Group laryngeal mask airway (n = 63) and Group ETT (n = 29).

Postperfusion Syndrome in Cadaveric Liver Transplantations: A Retrospective Study.

Objective: To evaluate the factors that affects the postperfusion syndrome in cadaveric liver transplantations and the effect of the postperfusion syndrome on discharge from the hospital.

Methods: Patients who underwent cadaveric liver transplantations between 2007 and 2013 were scanned retrospectively. Intraoperative anaesthesia records, intensive care unit follow-up forms and discharge reports were examined from patient files.

Hematological predictors and clinical outcomes in cardiac surgery.

Purpose: The present study was to investigate if five values that are part of the hemogram analysis routinely checked before heart surgeries can be used as a high-quality, quick, low-cost, and easy-to-use outcome predictor.

Methods: This investigation was a retrospective, observational, cross-sectional study. Univariate and multivariate logistic regression was used to identify independent predictors for combined adverse events.

CHALLENGES OF OBSTETRIC ANESTHESIA: DIFFICULT LARYNGEAL VISUALIZATION.

Obstetric anesthesia is one of the high risk subspecialties of anesthesia practice. Anesthesia related complications are the sixth leading cause of maternal mortality. Difficult or failed intubation following induction of general anesthesia for CS remains the major contributory factor to anesthesia-related maternal complications.

10 cm H2O PEEP application in laparoscopic surgery and cerebral oxygenation: a comparative study with INVOS and FORESIGHT.

Introduction: In the present study, changes in hemodynamic parameters and cerebral oxygen saturation (rSO2) associated with 10 cm H2O PEEP application were investigated, which is assumed beneficial for the respiratory functions and oxygenation during laparoscopic cholecystectomy (LC) applied at 30° head-up left side position. Data gathered via two devices, namely INVOS and FORESIGHT, were compared.

Methods: After both the ethics committee approval from the hospital and patients' written consents were obtained, patients undergoing elective laparoscopic surgery (only ASA I-II) were randomly divided into two groups (Clinical trials protocol NCT02071550).

Any increase in airway peak pressure and ETCO2 will result in increase in intracranial pressure which must be avoided during craniotomies.

A comparison of the effects of ketamine and remifentanil on renal functions in coronary artery bypass graft surgery.

We have investigated the effects of ketamine-based and remifentanil-based anesthetic protocol on perioperative serum cystatin-C levels, and creatinine and/or cystatin-C-based eGFR equations in terms of acute kidney injury in coronary artery bypass graft (CABG) surgery. Using a simple randomization method (coin tossing), patients were divided into the two groups and not-blinded to the anesthetist. Remifentanil-midazolam-propofol or ketamine-midazolam-propofol-based anesthetic regimen was chosen.

The effect of sevoflurane vs. TIVA on cerebral oxygen saturation during cardiopulmonary bypass--randomized trial.

Background: Neuropsychological and neurological deficits are still major causes of mortality and morbidity after cardiac surgery. These complications are thought to be caused by embolisms and cerebral hypoxia. Thus, continuous neuromonitoring is essential during cardiac surgery due to cerebral oxygen desaturation during different periods.

Can we gain an advantage by combining distal median, radial and ulnar nerve blocks with supraclavicular block? A randomized controlled study.

Purpose: The aim of this study was to compare the combined ultrasound-guided supraclavicular brachial plexus block (SCB) and distal median, radial, and ulnar nerve blocks, with the supraclavicular block alone.

Method: Sixty-two patients undergoing upper extremity surgery were randomized to supraclavicular only (Group S, n = 31) or supraclavicular + distal (Group SD, n = 31) group. Patients in Group S received 32 mL of 1.

Thrombi migration to atrium diagnosed by transesophageal echocardiography.

Two days before surgery in a 70-year-old man with renal cell carcinoma, transthoracic echocardiography showed a dense mass in the inferior vena cava, lying proximally, but no mass was observed in the right atrium. Intraoperative transesophageal echocardiography revealed unexpected tumor thrombi in the right atrium, and the surgical plan was changed. This case highlights the importance of intraoperative transesophageal echocardiography in patients with renal cell carcinoma.

Obesity and postoperative early complications in open heart surgery.

Purpose: We investigated the distribution of early clinical outcomes among normal, obese, and morbidly obese patients undergoing open heart surgery.

Methods: Medical records of 1,000 patients undergoing open heart surgery since February 2011 at our hospital were investigated retrospectively after permission was obtained from the Council of Education Planning of the hospital. The comorbidities and perioperative and discharge data were analyzed for 279 patients with a body mass index (BMI) score between 18 and <30 [non-obese reference group (NRG, n = 279)]; 166 patients with BMI between 30 and <35 [obese group (OG, n = 166); and 192 seriously obese patients with BMI ≥35 [extreme obese group (EOG, n = 192)].
