Filter by:Surgery for breast cancer is associated with significant pain. The serratus nerve block targets the interfascial plane either below or above the serratus muscle, blocking thereby the lateral cutaneous branches of the intercostal nerves. The purpose of this randomized controlled double-blinded study is to see whether the addition of a serratus nerve block to a general anesthesia results in a better postoperative pain control in patients undergoing surgery for breast cancer.
Worldwide, the rising incidence of obesity has led to the identification of an obesity related syndrome, called metabolic. This syndrome is characterized by central obesity, hypertension, insulin resistance and altered lipid levels. Taking into consideration the rising incidence of obesity, anesthetists will more frequently encounter patients with metabolic syndrome, in their everyday practice. Moreover, the comorbidities that are related to the metabolic syndrome, increase the risk for perioperative complications. Therefore, strategies that will evaluate and modify the risk will be of great importance in the management of these patients, in order to maximize peri-anaesthetic and surgical safety. The aim of the study is to assess the incidence of metabolic syndrome and the impact of its presence on the outcome of patients undergoing elective laparotomy.
The purpose of this research study is to examine the effects of routine anesthesia on infant brain oxygen levels. The investigators do not know how anesthesia effects blood flow in the brain of infants during surgery. This study will help the investigators detect possible blood flow changes in the brain for infants undergoing anesthesia. A monitor and sensors (NIRS or near-infrared spectroscopy) which use light to measure oxygen levels in the blood will be used. Sensors will rest on the child's skin and record measurements before, during and after the surgery.
This prospective randomized trial evaluated Parker Flex-It stylet as an alternative to manufacturer, s GlideRite® Rigid Stylet to aid intubation with the GlideScope in patients undergoing elective non-cardiac surgery that required general anesthesia with orotracheal intubation.
45 pregnant women undergoing cesarean section were enrolled in the study in november 2006 to march 2007. 2 ml of 0.5% levobupivacaine was added to 1 ml of saline in group I, 1 ml of 15 µcg of fentanyl in group II and 1 ml of 1,5 µcg sufentanil in group III by intratechal administration. Hemodynamic parameters, characteristics of sensory and motor blockade, peri-operative and postoperative visual analogue scale (VAS) pain scores, the time to the first analgesic requirement and adverse effects were recorded.
Until today there is no standard-monitoring to specifically reflect the analgesic component of general anesthesia. Quality and safety of general anesthesia are of major clinical importance and can be improved by limiting the administration of opioid analgesics to the minimum dose needed. This study therefore examines the quality of three different monitoring techniques (PhysioDoloris, MetroDoloris, Lille, France, SPI (Surgical Plethysmographic Index), GE Healthcare, Helsinki, Finland and AlgiScan, IDMed, Marseille, France) in assessing the level of analgesia during general anesthesia. Therefore a standardized painful stimulus is applied under different levels of analgesic drugs. The monitor's indices are compared to clinical signs such as an increase in heart rate and blood pressure.
The arterial blood pressure affects the ratio between filtration and reabsorption of fluids in the circulating blood volume and thereby the hematocrit. During induction of anesthesia blood pressure, hemoglobin level and hematocrit decreases. The aim of the study is to evaluate weather a maintained blood pressure with norepinephrine during anesthesia induction reduces the decrease in hematocrit.
Aspiration of gastric content is a rare but serious complication of anesthesia. In this context, preoperative fasting for elective surgery is well defined. In an emergency situation, international guidelines recommend rapid sequence of anesthesia to reduce the risk of aspiration. In semi emergency situation, there is no consensus about the anesthetic procedure even if a preoperative fasting has been observed due to uncertainty of gastric emptying related to stress or painful condition. The choice of anesthesia induction technique depends mainly on the anesthetist. Ultrasonography is a non invasive bedside tool that can provide reliable quantitative information about the volume of gastric content.
Dexmedetomidine can be used as a co-induction agent to facilitate laryngeal mask airway (LMA) insertion with minimal effect on respiratory function. The purpose of the study was to determine the median effective dose (ED50) of dexmedetomidine to facilitate LMA insertion during anaesthesia induction with propofol 2.0 mg/kg.
The aim of this prospective study is to determine the effect of pressure support ventilation (PSV) on minute alveolar ventilation (MAV) and end-tidal carbon dioxide (ETCO2) in anesthetized spontaneously breathing subjects by observing alterations of respiratory rate (RR), expiratory tidal volume, MAV and ETCO2 at variable levels of pressure support.
