A Comparison of the Effects of Lung Protective Ventilation and Conventional Ventilation on Thermoregulation During Anaesthesia.

Objective: During prolonged surgery, hypothermia is an unwanted condition that frequently develops and increases complication rates. It has been shown that positive end-expiratory pressure (PEEP) during mechanical ventilation reduces hypothermia development by providing earlier peripheral vasoconstriction. In the present study, an investigation was made of the effect of two different ventilation models on perioperative hypothermia development.

We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents.

Impact of a lung-protective ventilatory strategy on systemic and pulmonary inflammatory responses during laparoscopic surgery: is it really helpful?

Laparoscopic surgery is performed by carbon dioxide (CO2) insufflation, but this may induce stress responses. The aim of this study is to compare the level of inflammatory mediators in patients receiving low tidal volume (VT) versus traditional VT during gynecological laparoscopic surgery. Forty American Society of Anesthesiologists (ASA) physical status 1 and 2 subjects older than 18 years old undergoing laparoscopic gynecological surgery were included.

Evaluation of low tidal volume with positive end-expiratory pressure application effects on arterial blood gases during laparoscopic surgery.

Background: Pneumoperitoneum (PNP) and patient positions required for laparoscopy can induce pathophysiological changes that complicate anesthetic management during laparoscopic procedures. This study investigated whether low tidal volume and positive end-expiratory pressure (PEEP) application can improve ventilatory and oxygenation parameters during laparoscopic surgery.

Methods: A total of 60 patients undergoing laparoscopic surgery were randomized to either the conventional group (n = 30, tidal volume = 10 mL/kg, rate = 12/minute, PEEP = 0 cm H(2)O) or the low tidal group with PEEP group (n = 30, tidal volume = 6 mL/kg, rate = 18/minute, PEEP = 5 cm H(2)O) at maintenance of anesthesia.

Exploring for the safer ventilation method in laparoscopic urologic patients? Conventional or low tidal?

Background: To study the effects of low tidal volume with positive end-expiratory pressure (PEEP) on arterial blood gases of patients undergoing laparoscopic urologic surgeries.

Subjects And Methods: Eighty-six laparoscopic urologic patients were enrolled in this study. Patients were randomized into two groups according to the ventilatory settings.

Comparison of the effects of desflurane and propofol anesthesia on the inflammatory response and s100β protein during coronary artery bypass grafting.

Cardiopulmonary bypass (CPB) contributes to the secretion of anti-inflammatory cytokines that mediate the inflammatory response observed during open heart surgery. In addition to many factors, type of anesthesia management affects immune response and central nervous system in cardiac surgery. The aim of this study was to assess the effect of propofol versus desflurane anesthesia on systemic immune modulation and central nervous system on patients undergoing coronary artery bypass grafting.

Pleomorphic adenoma of the trachea.

Pleomorphic adenoma in the trachea is very rare. We report the case of a 46-year-old woman who had been treated for asthma for 12 months before the diagnosis of pleomorphic adenoma of the trachea was made. The tumour was defined by fiberoptic bronchoscopy in the mid 1/3 of the trachea obstructing nearly 90 % of the lumen.

Determining entropy values equivalent to the bispectral index values during sevoflurane anaesthesia.

Introduction: We aimed to identify the entropy levels that would be equivalent to the bispectral index (BIS) levels in sevoflurane anaesthesia in patients who are to undergo elective lumbar disc surgery.

Material And Methods: Thirty cases in ASA groups I-II who underwent lumbar disc surgery under general anaesthesia were included in our study after obtaining the consent of the patients and Ethics Committee of our medical school between January 1, 2005 and October 30, 2006. BIS and entropy electrodes were applied at the same time in 30 cases in the study group.

Advantages of autologous blood transfusion in off-pump coronary artery bypass.

Background: In this randomized controlled study, we investigated the effects of autologous Hemobag blood transfusion (AHBT) and allogenic blood transfusion (ABT) in off-pump coronary artery bypass (OPCAB) surgery.

Methods: Sixty patients who underwent surgery between February 2008 and August 2008 were randomized into 2 groups. The AHBT group (n = 30) consisted of patients who received autologous Hemobag blood transfusion, and the ABT group (n = 30) consisted of patients who received allogenic blood transfusion.

Gastrointestinal ischemia related mortality in patients undergoing off- or on-pump coronary artery bypass grafting.

Objective: Gastrointestinal ischemia (GII) after heart surgery is a rare but devastating condition. The aim of this study was to compare the occurrence of GII after coronary artery bypass grafting (CABG) performed off-pump (OPCAB) vs on-pump (ONCAB).

Methods: We retrospectively evaluated 2625 adult patients who underwent isolated coronary artery surgery during a 6-year period.

Recurrent hepatic hydatid cyst in a pregnant woman.

Background: Hydatid cyst in pregnancy is a very rare pathology and its diagnosis and treatment is still a complex problem. This report describes the clinical features and evolution of a pregnant woman operated for a recurrent hepatic hydatid cyst.

Case Report: A 26-year-old multigravida was admitted to our hospital in her 16th week of pregnancy because of dyspeptic complaints.

Preemptive analgesia in laparoscopic cholecystectomy: a randomized controlled study.

In pain control after laparoscopic cholecystectomy, subhepatic administration of bupivacaine immediately after the creation of pneumoperitoneum has been shown to be more effective than administration before the withdrawal of the trocars. We aimed to investigate the effect of intraperitoneal bupivacaine administration to the subhepatic area before the creation of the pneumoperitoneum. Eighty patients undergoing elective laparoscopic cholecystectomy under general anesthesia were included in a prospective, randomized study.

Cytotoxic effects of volatile anesthetics with free radicals undergoing laparoscopic surgery.

Background: Free radicals induced by several diseases can trigger oxidative stress, leading to the production of malondialdehyde (MDA) and protein carbonyl content (CB). Volatile agents are able to increase the extent of oxidative status. However, the effects of these agents together with pneumoperitonium (Pp) have not been reported.
