BACKGROUND AND OBJECTIVES: Preoperative use of flurbiprofen axetil (FA) is extensively adopted to modulate the effects of analgesia. However, the relationship between FA and sedation agents remains unclear. In this study, we aimed to investigate the effects of different doses of FA on the median Effective Concentration (EC50) of propofol. METHODS: Ninety-six patients (ASA I or II, aged 18-65 years) were randomly assigned into one of four groups in a 1:1:1:1 ratio...

BACKGROUND: The present study investigated the association between Postoperative Cognitive Dysfunction (POCD) and increased serum S100B level after Robotic-Assisted Laparoscopic Radical Prostatectomy (RALRP). METHODS: The study included 82 consecutive patients who underwent RALRP. Serum S100B levels were determined preoperatively, after anesthesia induction, and at 30 minutes and 24 hours postoperatively. Cognitive function was assessed using neuropsychological testing preoperatively and at 7 days and 3 months postoperatively...

Hydatid cyst in the cervical region is an extremely rare condition that can create challenges for anesthesiologists. Timely recognition of difficult airway and preparing the management plan is crucial to avoid life-threatening complications such as hypoxic brain damage. We describe a case of difficult airway management in a patient with massive cervical hydatid cyst. We used a low-dose ketamine-propofol sedation and lidocaine spray for local oropharyngeal anesthesia. Muscular relaxants were not used, and spontaneous breathing was maintained during intubation...

BACKGROUND: Postoperative Nausea and Vomiting (PONV) risk factors have not been defined for obstetric patients. In this study, our objective was to identify potential risk factors for PONV after cesarean sections performed under spinal anesthesia. METHODS: One cohort of patients submitted to cesarean under spinal anesthesia was used to investigate potential risk factors for PONV. The best numerical risk factors were dichotomized using chi-squared method. A conditional independence (incremental association method) casual network was used to select the best predictors for PONV...

Experts from the Brazilian Association of Allergy and Immunology (ASBAI) and the Brazilian Society of Anesthesiology (SBA) interested in the issue of perioperative anaphylaxis, and aiming to strengthen the collaboration between the two societies, combined efforts to study the topic and to prepare a joint document to guide specialists in both areas. The purpose of the present series of two articles was to report the most recent evidence based on the collaborative assessment between both societies. This first article will consider the updated definitions, treatment and guidelines after a perioperative crisis...

Myasthenia Gravis (MG) is an autoimmune disease characterized by weakness and fatigability of skeletal muscles, with improvement following rest. It is a disease of great significance to the anesthesiologist because it affects the neuromuscular junction. Robotic thymectomy has come up in recent times due to the minimally invasive nature and its advantages. This presents a new set of challenges for the anesthesia team, and here we present the various anesthesia considerations and perioperative management in a series of 20 patients who underwent robotic thymectomy...

BACKGROUND AND OBJECTIVE: The aim was to investigate the effects of Turkish classical music on pain and oxidative stress in patients undergoing oocyte pick-up. METHODS: The study was a randomized, controlled trial. The groups included were Group NM (Non-Music), control group; Group PM, which comprised patients who listened to music before the operation; and Group CM, which comprised patients who listened to music both before and during the operation. Blood was drawn prior to the operation to measure the oxidative stress values...

BACKGROUND AND OBJECTIVES: Postoperative nausea and vomiting (PONV) is a common and undesirable complication observed after laparoscopic cholecystectomy (LC). We investigated the effects of auriculoacupuncture (AA) on the prevention of postoperative nausea and vomiting in the immediate postoperative period of uncomplicated laparoscopic cholecystectomy. METHODS: Sixty-eight patients were randomly divided into two groups, auriculoacupuncture (n = 35) and control (n = 33) and then they were evaluated prospectively...

BACKGROUND: Cardiac surgery can produce persistent deficit in the ratio of Oxygen Delivery (DO2 ) to Oxygen Consumption (VO2 ). Central venous oxygen Saturation (ScvO2 ) is an accessible and indirect measure of DO2 /VO2 ratio. OBJECTIVE: To monitor perioperative ScvO2 and assess its correlation with mortality during cardiac surgery. METHODS: This prospective observational study evaluated 273 patients undergoing cardiac surgery. Blood gas samples were collected to measure ScvO2 at three time points: T0 (after anesthetic induction), T1 (end of surgery), and T2 (24hours after surgery)...

PURPOSE: This study aimed to investigate factors associated with postoperative Acute Kidney Injury (AKI) focusing on intraoperative hypotension and blood loss volume. METHODS: This was a retrospective cohort study of patients undergoing pancreas surgery between January 2013 and December 2018. The primary outcome was AKI within 7 days after surgery and the secondary outcome was the length of hospital stay. Multivariate analysis was used to determine explanatory factors associated with AKI; the interaction between the integrated value of hypotension and blood loss volume was evaluated...

BACKGROUND: Tranexamic acid was studied in four different dosage regimens and their efficacy was compared for perioperative blood loss reduction, blood transfusion requirements and deep vein thrombosis (DVT) complication. METHODS: Two hundred patients undergoing major orthopedic procedures were divided into five groups containing 40 each: placebo, low dose (bolus 10mg.kg-1 ), low dose+maintenance (bolus 10mg.kg-1 +maintenance 1mg.kg-1 .hr-1 ), high dose (bolus 30mg...

BACKGROUND: Skin conductance response reflects the activity of the sympathetic nervous system and is used to measure acute pain. This pilot study examines correlations of skin conductance response with emotional stressors postoperatively. METHODS: The correlation of skin conductance response with pain, anxiety, nausea and intellectual task performance was analyzed in postoperative patients. RESULTS: Significant correlations were observed between anxiety and pain during physical activity on both postoperative day 1 and 2...
