Filter by:The purpose of the study is to test a novel endotracheal tube support device that reduces pressure of the tube on the voice box for prevention of post intubation laryngeal symptoms including sore throat, change in voice and trouble swallowing.
We aim to compare the response to ketamine/dexmedetomidine and ketamine/propofol combinations used in hepatic patients with child-Pugh classification (class A), and early (class B) undergoing UGIE.
General anesthesia induces hemodynamic changes, notably a reduction of arterial blood pressure going up to 30%, that may impact cerebral perfusion and oxygenation.The purpose of this study is to assess the impact of anesthesia on the cerebral oxygenation, the perfusion of the brain (assessed with transcranial doppler), and the depth of anesthesia in children between 6 months and 5 years old during the induction of general anesthesia (induced with sevoflurane and/or IV agents). It is expected that the cerebral hemodynamic will be maintained despite systemic variations.
Sedation with dexmedetomidine-propofol or ketamine-propofol was planned in patients with upper gastrointestinal endoscopy.
In this study the goal is to determine the causes of concern among the patients who will undergo surgical operations and receive general anesthesia, to gauge their preoperative anxiety levels and to study the effects of the BATHE method on preoperative anxiety and patient satisfaction.
Objective: The present study was to evaluate the effects of dexmedetomidine alone, lidocaine alone and their combined infusion on postoperative inflammation cytokines after Laparoscopic hysterectomy. Methods: Investigators enrolled 160 women with American Society of Anesthesiologists (ASA) physical status I and II, aged 40-65 years, and scheduled for elective laparoscopic hysterectomy with general anesthesia from October 2017 to August 2018. The participants were randomly assigned into four groups(n=40 each group): group CON received normal saline infusion, group LIDO received lidocaine infusion (1.5 mg/kg loading, 1.5 mg/kg/h infusion), group DEX received dexmedetomidine infusion (0.5 µg/kg loading, 0.4 µg/kg/h infusion) and group LIDO+DEX received lidocaine (1.5 mg/kg loading, 1.5 mg/kg/h infusion) and dexmedetomidine infusions (0.5 µg/kg loading, 0.4 µg/kg/h infusion). The four groups received an IV bolus infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine respectively, over 10 minutes before induction of anesthesia, followed by a continuous IV infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine until abdominal wound closure, respectively. Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), the end of surgery (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4).
Subsequent and non-randomised patients, adult patients qualified for major abdominal surgeries were enrolled
This study evaluates the effects of different anesthetic techniques on QT, QTc, and Pwd in cesarean section. Half of participants received general anesthesia, while the other half received spinal anesthesia Electrocardiography (ECG) recordings were performed at preoperative, 5, 15, 30 min after initiation anesthesia and 30 min post-operatively. Hemodynamic state were also recorded at the same time intervals. QT, corrected QT (QTc), QT dispersion (QTd), QTc dispersion (QTcd), P-wave dispersion (Pwd), corrected JT interval, T wave (Tp-e), transmular dispersion of repolarization durations were measured from ECG records at predetermined time intervals of spinal or general anesthesia.
Anesthesia in the modern age is at least a two-drug process consisting of an opioid and a sedative hypnotic (e.g., fentanyl and propofol in combination, among others). Therefore, it is important to understand the interaction pharmacodynamics of these agents as they are used clinically. A good method for visualizing the pharmacodynamic interaction behavior of drug combinations is through response surface models. Unlike traditional isobolograms that represent the concentrations of two agents that combine to produce a single degree of drug effect, response surface models characterize the complete spectrum of interaction between two or more agents for all possible levels of concentration and effect. The investigators try to use the response surface model to evaluate the effect of anesthetic combination of autonomic system.
