Introduction: Obesity increases the risk of morbidity and mortality during surgical procedures. Goal-directed fluid therapy (GDFT) is a new concept for perioperative fluid management that has been shown to improve patient prognosis. This study aimed to investigate the role of the Pleth Variability Index (PVI), systolic pressure variation (SPV), and pulse pressure variation (PPV) in maintaining tissue perfusion and renal function during GDFT management in patients undergoing laparoscopic sleeve gastrectomy (LSG).

Purpose: Obese patients have a significantly higher risk of adverse effects associated with general anesthesia. The purpose of this study was to evaluate the effects of Patient State Index (PSI) monitoring on recovery from anesthesia and the incidence of any postoperative complications among patients undergoing bariatric surgery with total intravenous anesthesia (TIVA) and inhalational anesthesia.

Design: This prospective, double-blind, and randomized controlled trial was conducted between February 2017 and August 2017 and included 120 morbidly obese patients (body mass index >40 kg/m).

Background: The interest in and demand for post-bariatric surgery have increased along with the increase in obesity surgery. Belt lipectomy, during which a circular correction is made in the center of the trunk, is the most commonly performed among these surgical techniques. Postoperative pain is an important problem due to the size of the surgical site and stretched closure.

Purpose: Unexpected cancellations of planned elective procedures are a global problem for hospitals, causing a waste of hospital resources and manpower, and reduces the efficiency of hospitals. In this study, we tried to identify the causes of cancellations of elective procedures, and to examine the relationship between the causes.

Design: A retrospective, descriptive single-center study.

Background: Postoperative nausea and vomiting (PONV) is one of the most common complications during the postoperative period. In the literature, there are many factors associated with PONV risk, but it is claimed that inflammation increases this risk. The neutrophil-to-lymphocyte ratio (NLR) is a cheap parameter to use in the diagnosis and follow-up of systemic inflammatory diseases.

Objective: This retrospective study aimed to evaluate the effect of a restructured anaesthesia intensive care unit (ICU) on changes in infection rates and infections.

Methods: Organisational restructuring was done in the anaesthesia ICU of Firat University Hospital after it was relocated on 14 March 2012. This study was designed to investigate the effect of restructuring on infection rates through a comparison of periods encompassing one year before relocation and one year after relocation.

Background: There is no well-recognized guideline for intraoperative fluid management in bariatric surgery. Goal-directed fluid therapy (GDFT) is a new concept of perioperative fluid management which was shown to improve patients' prognoses. Dynamic indicators may better predict fluid response compared to static indicators.

Purpose: We evaluated the effects of body mass index (BMI) on thermoregulation in obese patients scheduled to undergo laparoscopic abdominal surgery.

Methods: Sixty patients scheduled to undergo laparoscopic abdominal surgery with no pre-medication were included in the study. The patients were classified into 4 groups according to BMI <24.

Introduction: Hepatic ischemia-reperfusion (I/R) injury is commonly observed in severe sepsis, hemorrhagic shock, liver transplantation, hepatic resection, and major trauma. Ketamine suppresses the production of cytokines, such as IL-6 and TNF-α, via NF-κB inhibition. We investigated the anti-inflammatory effects of ketamine in liver I/R injury.

Aim: To evaluate the effects of three different doses of gabapentin pretreatment on the incidence and severity of myoclonic movements linked to etomidate injection.

Method: One hundered patients, between 18 and 60 years of age and risk category American Society of Anesthesiologists I-II, with planned elective surgery under general anesthetic were included in the study. The patients were randomly divided into four groups and 2h before the operation were given oral capsules of placebo (Group P, n=25), 400mg gabapentin (Group G400, n=25), 800mg gabapentin (Group G800, n=25) or 1200mg gabapentin (Group G1200, n=25).

Aim: Lumbar disc surgery can be performed under general anesthesia or regional anesthesia methods. There are long-standing discussions between neurosurgeons, orthopedic surgeons and anesthesiologists concerning the use of epidural anesthesia in lumbar surgery. The results of this study's 700 lumbar disc surgery cases operated with epidural anesthesia in our clinic between September 2006 and December 2011 will contribute to these discussions.

Objective: The aim of this study was to retrospectively evaluate the intensive care unit treatments applied to obstetrics patients with a diagnosis of posterior reversible encephalopathy syndrome (PRES).

Material And Methods: The cases of 7 pregnant patients who had been diagnosed with PRES between July 2011 and July 2013 were retrospectively reviewed. The patients' clinical data, brain magnetic resonance imaging (MRI) images before and after treatment, and neuropsychological tests were evaluated.

Objective: To determine the serum tenascin-C (TN-C) levels in cases with mild and severe preeclampsia.

Methods: Pregnant women were divided into three groups, namely healthy pregnants (Group 1, n = 20), pregnants with mild preeclampsia (Group 2, n = 20) and pregnants with severe preeclampsia (Group 3, n = 20). The groups were formed so as to match each other in terms of gestational week.

A 19-year-old male patient who wounded himself with a gun in the cranial region had a Glasgow coma scale of 3E. At posttraumatic day 7, locked-in syndrome was considered upon detection of vertical eye movements, meaningful winks, and quadriplegia. Apart from the classical view, computed tomography (CT) and postmortem examination of the brain showed an infarct area in the cerebellum.
