Randomized Controlled Trial
Effects of high thoracic epidural anesthesia on mixed venous oxygen saturation in coronary artery bypass grafting surgery.
To investigate possible effects of high thoracic epidural anesthesia (HTEA) on mixed venous oxygen saturation (SvO2) in coronary artery bypass grafting surgery (CABGS) MATERIAL AND METHODS: Sixty-four patients scheduled for CABGS were randomly assigned to either test (HTEA) or control group. Standard balanced general anesthesia was applied in both groups. Mean arterial blood pressure (MAP), heart rate (HR), oxygen saturation (SpO2), central venous pressure (CVP), cardiac output (CO), cardiac index (CI), systemic vascular resistance (SVR), pulmonary vascular resistance (PVR), mean pulmonary arterial pressure (PAP), pulmonary capillary wedge pressure (PCWP), pulmonary compliance (C), bispectral index (BIS), body temperature, SvO2, hematocrit values were recorded before induction. Postoperative hemodynamic changes, inotropic agent, need for vasodilatation, transfusion and additional analgesics, recovery score, extubation time, visual analogue scale (VAS) values, duration of stay in intensive care unit (ICU) and hospital were recorded. ⋯ HTEA may improve balance between oxygen presentation and usage by suppressing neuroendocrin stress response; provide efficient postoperative analgesia, more stabile hemodynamic, respiratory conditions, lower duration of stay in ICU, hospital.

Hypotension is a common adverse effect of IV anaesthetics, especially during the induction of anaesthesia. The aim of our study was to determine the incidence and risk factors for intraoperative hypotension (IOH) in thyroid surgery, as well as to determine whether and to what extent IOH affects the occurrence of postoperative hypotension. ⋯ IOH is common, even during operations of short duration and with minimal bleeding. It is necessary to pay special attention to these patients, given that many of these patients remained hypotensive during the postoperative period.

Randomized Controlled Trial
Effects of preoperative oral carbohydrate solution intake on thermoregulation.
We aimed to investigate the oral carbohydrate solution administered preoperatively on thermoregulation. ⋯ Oral carbohydrate solution administered was established to have effects thought to be negative on tympanic temperature, vasoconstriction, and vasoconstriction threshold.

Comparative Study
Spinal anesthesia with hyperbaric bupivacaine: a comparison of hypertensive and normotensive patients.
Hypotension is the most common problem with spinal anesthesia. This prospective study aimed to compare normotensive and hypertensive patients with respect to the hemodynamic effects of spinal anesthesia performed with hyperbaric bupivacaine. ⋯ There was no significant difference between normotensive and hypertensive patients in the incidences of hypotension caused by spinal anesthesia with 0.5% hyperbaric bupivacaine.

Comparative Study
Arterial distensibility in patients with ruptured and unruptured intracranial aneurysms: is it a predisposing factor for rupture risk?
A risk factor assessment that reliably predicts whether patients are predisposed to intracranial aneurysm (IA) rupture has yet to be formulated. As such, the clinical management of unruptured IA remains unclear. Our aim was to determine whether impaired arterial distensibility and hypertrophic remodeling might be indicators of risk for IA rupture. ⋯ Patients with ruptured IAs demonstrated decreased arterial distensibility and increased intima-media thickness at the level of the carotid arteries. By measuring these parameters via ultrasound, it may be possible to predict whether patients with existing IAs might rupture and hemorrhage into the subarachnoid space.
