Plethysmographic variability index and perfusion index in patients with axillary brachial plexus nerve catheters: An observational study.

Axillary nerve blocks are commonly using for forearm and hand surgery. Especially for finger replacement it has been shown continuous plexus blockade improves microcirculation. Addition to that benefit continuous blockade provides adequate analgesia.

Coexistence of familial Mediterranean fever and Behçet's disease: a case report.

Behçet's disease (BD) is a chronic, multi-systemic vasculitis, characterized by a triad of recurrent aphthous stomatitis, genital aphthae, and uveitis. It is common in the Eastern Mediterranean, Middle East, and Eastern Asian countries. Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder, which is common seen in the Turkish, Armenian, Arabic, and Sephardic Jewish populations.

Long-Term Changes in Subfoveal Choroidal Thickness After Cataract Surgery.

BACKGROUND Cataract surgery is associated with the development of late-onset age-related macular degeneration (AMD). The pathogenic mechanism is still not fully established. The purpose of this study was to evaluate the possible changes in central macula thickness (CMT) and subfoveal choroid thickness (SCT) after uneventful cataract surgery.

Coexistence of Familial Mediterranean Fever With Ankylosing Spondylitis and Sjogren's Syndrome: A Rare Occurrence.

Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent episodes of fever, peritonitis, synovitis, pleuritis, and erysipelas-like skin lesions. Sjogren's syndrome is a chronic autoimmune disorder characterized by dry eyes, dry mouth, and musculoskeletal involvement. Ankylosing spondylitis is an autoinflammatory rheumatic disease which affects mainly the axial skeleton.

Dry eye in vitamin D deficiency: more than an incidental association.

Aim: The aim of this article is two-fold: (i) to demonstrate the relation between vitamin D deficiency and dry eye and impaired tear function; and (ii) to investigate the possible associations among clinical parameters of hypovitaminosis D with dry eye parameters.

Method: Fifty premenopausal women with vitamin D deficiency (serum vitamin D levels < 20 ng/mL) and 48 controls were included. Participants were assessed by Schirmer's test, tear break-up time test (TBUT), ocular surface disease index (OSDI), Stanford Health Assessment Questionnaire (HAQ), fatigue severity scale (FSS), and visual analogue scale-pain (VAS-pain).

Comparison of the effect of sevoflurane and propofol on oxygenation during gradual transition to one-lung ventilation.

Background: It is known that hypoxic pulmonary vasoconstriction increases as a result of intermittent regional hypoxic challenges. The aim of this study was to compare the effects of sevoflurane and propofol on oxygenation and shunt fraction during one-lung ventilation in a novel model of hypoxic preconditioning before one-lung ventilation.

Methods: Sixteen Wistar-albino rats were anesthetized intra-peritoneally before venous and arterial cannulations and tracheotomized.

A new technique for long time catheterization of sacral epidural canal in rabbits.

Introduction: In this study we aimed to develop a simple and practical technique for chronic sacral epidural catheterization of rabbits.

Methods: We included ten rabbits weighing 2-2.5 kg in the study.

Use of airway exchange catheter for bronchoscopy of a patient with Down's syndrome.

Tracheobronchial injuries (TBI) are highly fatal, and early diagnosis and repair are crucial for survival. The anesthesiologist and the surgeon must secure the integrity and patency of the airway for these cases. These injuries remain infrequent, and are becoming less fatal due to the availability of the resources necessary to achieve a secure airway, and thus some of them can be managed conservatively.

Ischaemic preconditioning attenuates haemodynamic response and lipid peroxidation in lower-extremity surgery with unilateral pneumatic tourniquet application: a clinical pilot study.

Introduction: The harmful effects of ischaemia-reperfusion on skeletal muscle during extremity surgery can be diminished by using medications or ischaemic preconditioning

Methods: Twenty patients undergoing lower-limb surgery with use of a tourniquet for at least 1 hour were included in the study and randomised into two groups: a control group with only tourniquet application (T group; n=10); and an ischaemic preconditioning plus tourniquet group (IP-T group; n=10). Blood samples were obtained from the femoral vein of the relevant extremity before tourniquet application (baseline), immediately after tourniquet deflation (TD), at 10 minutes after the tourniquet deflation (TD(10min)) in the T group and additionally after ischaemic preconditioning in the IP-T group. Venous blood pH, partial oxygen pressure (P(vO2)), partial carbon dioxide pressure (P(vCO2)), lactate, potassium, sodium and glucose levels were analysed using a blood gas analyser.

The safe limits of mechanical factors in the apnea testing for the diagnosis of brain death.

Apneic oxygenation is an apnea testing method in the diagnosis of brain death. In this method, oxygen (O2) is delivered into the trachea via an O2 catheter (O2C). However, barotrauma may develop during O2 insufflation into the trachea.

A new method for estimating arterial occlusion pressure in optimizing pneumatic tourniquet inflation pressure.

To reduce pressure-related injuries resulting from pneumatic tourniquet use, the lowest possible inflation pressure is recommended. Arterial occlusion pressure (AOP) is a measure of the cuff pressure required to maintain a bloodless surgical field. However, its determination method is time consuming, requires operator skill, and is therefore seldom used in current practice.

Dilution of rocuronium to 0.5 mg/mL with 0.9% NaCl eliminates the pain during intravenous injection in awake patients.

In a randomized, double-blinded, controlled study, we evaluated the effect of diluting rocuronium 10 mg/mL to 1 or 0.5 mg/mL with 0.9% NaCl on the pain associated with IV administration of rocuronium with small doses given before succinylcholine or nondepolarizing agent administration.

Controlled hypotension and minimal inflation pressure: a new approach for pneumatic tourniquet application in upper limb surgery.

Unlabelled: Minimal inflation pressures are recommended for limb surgery to eliminate complications attributable to high inflation pressures with the pneumatic tourniquets. We applied controlled hypotension and a minimal inflation pressure (CHAMIP) technique to provide a bloodless surgical field. Thirty-six patients scheduled for upper extremity surgery were randomized equally to receive either normotensive anesthesia and conventional inflation pressures or controlled hypotension (systolic arterial blood pressure of 80-100 mm Hg and mean arterial blood pressure >60 mm Hg) and minimum inflation pressures.
