Filter by:Pulse CO-Oximetry (Masimo Corp, Irvine, CA, USA) is a method that allows non-invasive continuous hemoglobin (Hb) measurement. This technology measures continuous Hb with a multi-wavelength spectrophotometric fingertip sensor. Aim of investigators in this study is to make continuous Hb measurement with Pulse CO-Oximetry method in living liver donors, to compare these measurements with the laboratory results routinely taken during the operation, to determine the level of correlation for this patient group.
The aim of this study is to assess the effectiveness and usefulness of the current practice of various examinations ordered by anesthesiologists during the pre-anesthetic evaluation in patients who are intended for elective surgery in our hospital. We will also evaluate the effect of delay & its value to predict postoperative complications.
Several studies demonstrated the effectiveness of OFA in patients undergoing non-cardiac surgery. Preoperative use of Cox inhibitors, GABA analogues and acetaminophen have been shown to decrease use of opioids postoperatively . Intraoperative use of agents that lead to opioid sparing effects via sodium channel blockade, blockade of G protein-coupled receptors, NMDA blockade, central alpha-2 agonists and anti-inflammatory effects can make opioid-free anesthesia (OFA) possible. On the other hand, there have been no studies demonstrating the effectiveness of an OFA technique in patients undergoing cardiac surgery except for two case reports who successfully implemented the OFA regimen in two patients undergoing valve replacement surgeries. The investigators therefore propose this prospective randomized controlled trial to investigate whether a multimodal opioid-free anesthesia regimen will be suitable as an alternative to conventional opioid-based regimen in patients undergoing valve surgery
Sleeping model can be affected after surgery. Anesthetics may be involved in the change. The changing of sleeping mode may exert adverse effect on postoperative recovery. Acupuncture and related techniques has been used for treating sleeping disorder. In this study, the effect of transcutaneous electrical acupoint stimulation on sleeping model after general anesthesia will be observed.
The investigators propose to evaluate the analgesic effect of medical hypnosis prior to the pharmacological induction of general anesthesia versus a classical pharmacological induction of anesthesia. Monitoring of the NOL index (Nociception index) as well as all the other classical parameters under general anesthesia (heart rate, blood pressure etc) will allow evaluation of the level of nociception related to oro-tracheal intubation as well as the one related to standardized electrical tetanic stimulation during general anesthesia and before surgical incision, between the two groups. The investigators know from the literature that the use of medical hypnosis in combination with anesthetic drugs allows for a significant reduction of hypnotic and opioid drugs. The investigators aim here at evaluating the real and objective impact of pre-anesthesia hypnosis on intraoperative nociception by using the NOL index which has been developed and used recently to better detect nociceptive stimuli under anesthesia. This clinical trial will provide an objective answer on the analgesic properties of intraoperative hypnosis. If this is confirmed, hypnosis could find its place in the management of perioperative nociception around general anesthesia.
This randomized double-blind study aimed to compare the effects of dexmedetomidine and ketamine on hemodynamic parameters, recovery criteria, and opioid consumption and advers effects in septorhinoplasty operations. Totally 63 patients were included. The groups were compared in terms of hemodynamic values, recovery times, postoperative agitation, sedation, activity, modified Aldrete and pain scores, side-effects and additional analgesia requirements at postoperative 24h.
In order to effectively treat surgical pain with the least amount of opioids required, a multi-modal approach must include medications with different mechanisms of actions at alternative receptors. In light of the opioid epidemic, medical providers at Vanderbilt University Medical Center (VUMC) are strategically combining these medications in a bundled pain-regimen after surgery. These regimens have been shown to decrease opioid consumption, improve surgical outcomes, and reduce hospital stays, thus coining the term 'enhanced recovery pathway'. The combination of these medications has an indisputable synergistic effect. However, it is unknown how each medication contributes individually to the overall efficacy of the pathway. This study will examine the effects of ketamine, within the constructs of a multimodal pain regimen, on a) length of stay, b) opioid consumption, and c) surgical outcomes after major abdominal surgery.
To investigate the relationship between BIS™ and inhaled anesthetics across a wide range of anesthetic concentration and hypnotic states, and to provide evidence to support BIS™ performance in use with Isoflurane, Sevoflurane and Desflurane in combination with opioids.
The aim of the trial is to study the efficacy of bilateral Erector Spinae Plane Block (ESPB) in managing perioperative pain in patients who undergo elective laparoscopic cholecystectomy
Postoperative quality of recovery (QoR) could be related to anesthesia and postoperative analgesia. This study is exploring early QoR after radical prostatectomy in the two groups of anesthesia. The first group had a light general anesthesia with lumbal epidural anesthesia and postoperative epidural analgesia with morphine and ropivacaine. The second group had general anesthesia and a continuous postoperative analgesia with tramadol. The postoperative QoR was evaluated 24 hours after surgery.
