Filter by:This study aims to compare the efficacy of dexmedetomidine versus fentanyl during general anesthesia for patients with morbid obesity undergoing laparoscopic sleeve gastrectomy.
Ketamine is a commonly used drug for sedation and induction of anesthesia in patients with shock and/or cardiac dysfunction. Ketamine is characterized by its cardiovascular stimulatory effect due to increase release of endogenous catecholamines. On the other hand, laboratory data on the isolated human myofibers suggest that ketamine had a direct myocardial depressive effect; accordingly, many experts believe that ketamine might have a negative hemodynamic effect in catecholamine depleted patients such as critically ill patients. In critically ill patients, there are contradicting results for the effect of ketamine on the hemodynamic profile and there is paucity of clinical data about the effect of ketamine on cardiac contractility and cardiac output (CO). Cardiac output is the primary determinant of global oxygen delivery to organs and maintaining stable CO in critically ill patients is at most importance to avoid further organ damage in such patients. Therefore, this study is designed to evaluate the effect a single bolus of ketamine on CO in patients with septic shock in comparison to fentanyl bolus.
The perioperative management of pain following abdominal surgery can pose a challenge to anesthesia providers. Conventional practice has involved the use of opioids as well as neuraxial analgesic techniques. Unfortunately, these therapies are not without potential risks and side effects. These include nausea, vomiting, pruritus, urinary retention, constipation, respiratory depression, and sedation.
Since the 1970s, ketamine has been used in clinical anesthesia treatment. Compared with ketamine, esketamine has a higher clearance rate, so it has a shorter recovery time after anesthesia. This feature also makes ketamine more suitable for pediatric dental patients.The purpose of this study was to investigate and compare the efficacy of esketamine sedation and fentanyl sedation in pediatric dental patients
Central neuraxial analgesia has been extensively used for labor analgesia and is currently the gold standard technique for pain control in obstetrics. The aim of the study will be to compare the role of dexmedetomidine or fentanyl as additives to epidural levobupivacaine in painless vaginal delivery as regard maternal analgesia and safety.
The best opioid for bronchoscopy is still unclear.This randomized double-blind prospective study was conducted on a total of 60 patients who were randomly allocated into 3 groups: Group S received sufentanil 0.1 mcg/kg, Group F received fentanyl 1 mcg/kg and Group R received remifentanil target-controlled infusion with effect-site target concentration of 1ng/ml. Patients in all groups received midazolam to achieve moderate levels of sedation as assessed by the Narcotrend (NT; between B1 and C2). Adverse events, patient tolerance and physician satisfaction were analized.
In sedation applications performed by an endoscopist or anesthetist during colonoscopy, it was investigated whether there were differences in pain levels evaluated by VAS (Visuel analog scale), patient satisfaction, duration of procedure and side effects
CONTEXT: In patients eligible for coronary artery bypass surgery, anesthesia should provide a number of conditions that exceed the limits of cardiovascular stability, myocardial protection and other organs. Moreover, the combination of general anesthesia and spinal anesthesia lessens the homeostatic, metabolic, hormonal and immunosuppressive changes. The goal of this research was to evaluate the consumption of fentanyl citrate in intra-operative in Coronary Artery Bypass Grafting (CABG) surgery with cardiopulmonary bypass under spinal anesthesia associated with general anesthesia. METHODS: Clinical, prospective, randomized and double covered study, approved by the Research Ethics Committee. Fifty-six patients candidates for CABG with CPB, after signing the Terms of consent, were randomized and divided into two groups: GI - General and GII - General + subarachnoid. General anesthesia was induced according to the weight of each patient and maintenance with isoflurane and fentanyl. Spinal anesthesia was induced with 20 mg of 0.5% hyperbaric bupivacaine and 200 mcg of morphine, the patient is placed in cephalo-position slope of 45 degrees for 10 minutes in Group II. In the statistical study was performed using the Mann-Whitney test; the level of statistical significance was set at 5%.
This study will investigate the influence of intra-operative use of remifentanil versus fentanyl on the percentage of patients with chronic thoracic after cardiac surgery via sternotomy. Secondary quantitative sensory testing is performed to determine thermal and electrical detection and pain threshold and the difference in pain variability scoring. Postoperative pain scores, analgesic use, genetic variances and costs are measured.
