Filter by:This study investigates the influence of type of anesthesia on survival and recurrence rate in patients receiving colon cancer surgery. The participants will be allocated to either the TIVA group and the inhalation group.
The investigators designed a multi-center prospective randomized controlled trial to study the influence of the type of anesthesia on postoperative pain after laparoscopic colorectal cancer surgery. Half of the participants will be anesthetized with propofol and remifentanil, while the other half will be anesthetized with sevoflurane and remifentanil during the surgery. The investigators will measure opioid consumption and pain score in the acute postoperative phase.
Propofol is an extensively utilized intravenous sedative and general anesthetic. However, propofol has a narrow therapeutic index, and this means that there is only a small difference in the dose required to produce loss of consciousness and the dose required to produce potentially life-threatening effects such as loss of protective airway reflexes and cessation of spontaneous breathing. Moreover, there is substantial variation between individuals in the doses required to achieve these pharmacodynamic endpoints. Given the inexorable rise in demand for pediatric sedation and the increasing use of propofol in sedation protocols by non-anaesthesiologists, the purpose of this study is to refine the propofol dosing recommendations to account for pharmacogenomic variability to make procedural sedation safer for children. Experienced users already adjust for age and body weight. This study may enable further refinements according to sex and - novelly - ancestry.
The aim of the project is to investigate whether the use of the HPI can reduce the number and duration of intra- and postoperative hypotension in ventilated patients during and two hours after extensive surgery in the head and neck area compared to the established monitoring.
Brain oxygenation of adult patients undergoing prehospital emergency anesthesia is monitored using noninvasive near-infrared spectroscopy. Patients are afterwards interviewed to define neurological outcome to measure quality of life. The purpose of this study is to reveal the risk factors of prehospital anesthesia related cerebral desaturation events (CDE) and to define the association between CDE and survival, neurological outcome or quality of life.
A comparison of post-operative opioid use in laparoscopic bariatric surgery patients receiving opioid or opioid-free anesthesia.
To determine the success rate of the AVATAR audio-visual system. All patients enrolled in the study will be counted, and each patient who is able to undergo at least one fraction without anesthesia will count as a success while each patient who does not have at least one fraction without anesthesia will count as a failure. The success rate will be the proportion of patients who are successes.
Research regarding the effects of anesthesia on the central nervous system remain controversial with some studies suggesting a neurotoxic effect and others indicating a neuroprotective effect. In recent years numerous neuronal proteins have been found to be useful tools for diagnosis and prognosis of cerebral tissue damage. Among these neuronal proteins are the following markers: Neuron Specific Enolase (NSE), Tau protein, Glial Fibrillary Acidic Protein (GFAP), Ubiquitin Carboxy-Hydrolase L1 (UCH-L1). BIS is a non-invasive brain monitoring technology which monitors the depth of anesthesia. In this randomized clinical trial, we aim to examine the effect of anesthetic method (General anesthesia and neuroaxial anesthesia) on neuronal damage as measured by NSE serum levels. One hundred and forty patients aged 18 and above undergoing Transurethral resection of the prostate, Trans Urethral Resection of the Bladder Tumor, Tension Free Vaginal Tap , Trans Obturator Tension Free Vaginal Tap and pelvic floor repair surgeries will be enrolled in the study. Patients will randomly be assigned to undergo the study either under general anesthesia or with neuroaxial anesthesia. Participants will be monitored using the BIS monitor, to measure the depth of anesthesia. Additionally, 9 cc of venous blood be collected from each participant in the surgery room prior to anesthesia induction, throughout anesthesia and one hour following surgery in the PACU in order to assess NSE levels.
Improve understanding of the correlation between surface EEG and implanted EEG recordings
Maternal hypotension during spinal anaesthesia for Caesarean delivery may bring various adverse effects. It is therefore important to closely monitor hypotension during spinal anaesthesia, however current technology does not allow the blood pressure monitoring to respond in timely manner should there be any occurrence of hypotension. The investigators developed an advanced double-intravenous vasopressor automated system (ADIVA) so as to tackle this issue via novel algorithm to control blood pressure more rigorously with more stable haemodynamic profiles.
