Individual Cerebral Hemodynamic Oxygenation Relationships

This is a randomized controlled trial in patients who require clinical anesthesia. The main purpose of this study is to understand whether there are differences in the cerebral blood flow, and oxygen metabolism affected by two types of anesthesia: propofol or sevoflurane. Subjects who require clinical anesthesia for a clinical MRI and for whom the use of propofol and sevoflurane are in clinical equipoise will be offered to have the anesthesia they will receive during their MRI randomized. All eligible subjects will be asked to provide informed consent before participating in the study.

Impact of NOL Intraoperative Guided Fentanyl Analgesia vs SCC for Elective Major Abdominal Surgery

Recently, a newly developed index, the Nociceptive Level (NOL) index, was validated and showed superiority over heart rate and blood pressure for recognition and grading of intense and mild nociceptive stimuli during surgery under general anesthesia. We hypothesize that compared with standard management, NOL-guided anesthesia will lead to reduced postoperative pain scores, and during anesthesia, to increased hemodynamic stability.

Comparison of Articaine Mandibular Infiltration to Lidocaine Inferior Alveolar Nerve Block in Pediatric Patients

This is a prospective, single-blind, parallel-design randomized controlled clinical trial that aims compare the effectiveness of articaine local infiltration to lidocaine inferior alveolar nerve block (IANB) for restorative treatment of primary mandibular molars (PMM). Four to 10-year-old children who needed PMM restorations are enrolled according to inclusion criteria and randomly allocated into the articaine or lidocaine group. One operator administers all local anesthesia (LA). Using the Modified Behavioral Pain Scale, 15 trained and calibrated examiners, blinded to LA type, evaluate the subjects' reactions during LA administration and treatment. Children rate their experience using the Wong-Baker FACES Pain Rating Scale. Subjects' blood pressure and pulse throughout the visit are recorded. Results are statistically analyzed using independent t-tests, Mann Whitney-U, and Repeated Measures ANOVA (P<0.05).

Evaluation of Intravenous Lidocaine and Time to Regression of the Sensory Block After Spinal Anesthesia (ELSA Trial)

The use of intravenous lidocaine in continuous infusion in the perioperative period is associated with a reduction in postoperative pain scores, opioid use, incidence of nausea and vomiting, among other favorable outcomes. However, this therapeutic intervention has not yet been adequately evaluated by clinical trials when associated with regional anesthesia. The aim of this study is to evaluate whether the use of intravenous lidocaine in continuous infusion during spinal anesthesia with isobaric bupivacaine alters the time to regression of sensory block in patients undergoing surgical procedures for the treatment of bone and connective tissue tumor surgeries. This will be a triple-blind randomized trial. The sample size estimated was 66 patients. The study will include all patients who meet the pre-established inclusion and exclusion criteria, choose to participate, and agree with the Informed Consent Form. The main anesthetic technique will be spinal anesthesia with 13 mg of isobaric bupivacaine. Patients will be allocated in two groups in a blindly after randomization: Group S (lidocaine 0.75mg.kg-1 in bolus followed by infusion of saline solution) and Group L (lidocaine 1.5 mg.kg-1 followed by continuous infusion of lidocaine solution at 2 mg.kg-1.h-1). The primary outcome will be the time to T12 regression of the sensory block. Will also be evaluated: time to regression of the motor block, most rostral dermatome achieved by the sensory block, time to two-segment regression oh the sensory block, propofol dose in the operating room, postoperative pain score at rest, pain at movement score, quality of recovery, use of opioids in the postoperative period, nausea or vomiting, dizziness, shivering, arrhythmias, hypotension, urinary retention, and length of stay. The records will be assigned to the RedCap database. The data will be extracted without identification of the allocation groups for the R software and the groups will be revealed to the researcher after the end of the statistical analysis to write the summary of the results. The results will be submitted to scientific journals afterward.

Validation of the QoR-15 Score for Emergency Surgery

Recovery from surgery is a complex process, depending on the characteristics of the patient, the anesthesia used, and the time required for surgical management. In the context of emergency surgery, the perioperative period is associated with an increase in morbidity and mortality, which may lead us to suspect an alteration in the quality of recovery. Different scales to measure the quality of post-operative recovery have been developed. The QoR-40 and QoR-15 questionnaires assess recovery after elective surgery.These scoring tools accurately measure postoperative recovery by addressing key domains: pain, physical comfort, physical independence, psychological support and emotional state. Their use is recommended as an endpoint for assessing patient comfort in clinical trials, according to the Standardized Endpoints in Perioperative Medicine (StEP) initiative. In addition, monitoring of the QoR-15 is recommended by the American Society for Enhanced Recovery. A recent French translation of the QoR-15 score has been validated for use in scheduled surgery. All of these scores, regardless of the language in which they are translated, have been developed and validated in patients who have undergone scheduled surgery. Until now, no validated scoring tool has been available to assess recovery after emergency surgery, whether traumatological or not.

General Versus Regional Anesthesia and Postoperative Sleep Quality

Major surgery can lead to postoperative disturbances in sleep patterns with subjective deterioration of sleep quality according to patients' reports as well as objective alterations of sleep architecture, as recorded by polysomnography Factors implicated in postoperative sleep disturbances include but are not limited to the severity of the surgical procedure, the neuroendocrine response to surgery, inadequate treatment of postoperative pain and external factors interfering with sleep, such as light, noise and therapeutic procedures There are no adequate data from current literature as to whether regional anesthesia is superior to general anesthesia regarding postoperative sleep quality in patients subjected to either mode of anesthesia. So, the aim of this study will be to assess the effect of two different anesthetic techniques (general versus regional) in patients subjected to similar operations Patients will be assessed with the Pittsburgh Sleep Quality Questionnaire (PSQI), regarding preoperative and long term postoperative sleep quality and sleep diaries regarding early postoperative sleep quality

The Impact of Perioperative Ketamine Infusion on Surgical Recovery

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, c) pain scores, and d) surgical outcomes after major abdominal surgery.
