12 Clinical Trials for Various Conditions
Protective airway reflexes may be impaired in the postoperative period, creating the potential for aspiration of gastric contents, even after a patient exhibits appropriate response to command. Because assessment of airway reflex recovery is not possible in an intubated patient, the clinician must make an empiric decision as to when a patient is safe to extubate, and choose a combination of techniques least likely to result in pharyngeal impairment. Adequacy of reversal of neuromuscular block by cholinesterase inhibitors (e.g., neostigmine) is unpredictable, especially in the presence of profound paralysis, and tactile assessment of train-of four and sustained tetanus has shown poor correlation with objective assessments. Protective airway reflexes may also be impaired during early recovery by the anesthetics themselves, even when muscle relaxant has been avoided. In the absence of muscle relaxant the investigators previously demonstrated that patients receiving an anesthetic with higher tissue solubility, sevoflurane showed significantly greater impairment of swallowing up to 14 minutes after response to command compared to patients receiving an anesthetic with lower tissue solubility, desflurane. Therefore, we ask whether the combination of the more soluble anesthetic and the presence of neuromuscular block antagonized by neostigmine may create a multiplicative effect that might further prolong pharyngeal recovery. We plan to randomly assign 100 patients scheduled to undergo surgery with general anesthesia to a standardized anesthetic that includes 1) sevoflurane, rocuronium with 70 µg/kg neostigmine + 14 µg/kg glycopyrrolate antagonism (group S); or 2) desflurane, rocuronium with 70 µg/kg neostigmine + 14 µg/kg glycopyrrolate antagonism (group D). Airway reflex recovery will be judged as adequate by the patient's ability to swallow 20 mL of water without coughing or drooling 5, 10, 15, 20, 30 and 60 minutes after response to command. Anesthetic (sevoflurane or desflurane) will be discontinued after administration of reversal agent and recovery to TOF (train-of-four) ratio of 0.7.
General anaesthesia is a reversible drug-induced coma. Too little can result in patients being partially conscious during surgery; too much can slow recovery after surgery. There is a range of drug doses that can be used and some anesthesiologists use more than others. There is no convincing evidence that any particular dose within the usual range is better. Consequently, there are no guidelines on the best depth of anaesthesia. This study will determine whether general anesthetic concentrations at the low end of the usual range are better than those at the high end. Participants will randomly be assigned to lighter or deeper general anesthesia. The first day after surgery, two short questionnaires about recovery and memories of the surgery will be completed. During the rest of the participant's hospital stay, a survey about how one feels will be completed. There will be two telephone contacts after discharge from the hospital. One month after surgery three questionnaires will be completed about performing daily tasks, how you feel and memories of the surgery. Then one year after surgery pain will be assessed.
The goal of this clinical trial is to compare lidocaine without epinephrine to papaverine a known vasodilatory agent, in creating improved motor strength in patients with drop foot involving an entrapment of the Common Peroneal Nerve. This phenomenon has been named the Phoenix Sign and is a very specific peripheral nerve block. Researchers will compare the effects of the above agent for pre and post infiltration changes in motor strength. Participants will: * Will be randomized to one of either agents already listed * After receiving the ultrasound guided injection, motor testing will be evaluated in 4-6 minutes with manual motor strength testing of the anterior compartment muscles. * No additional follow will be required
In this study, the investigators will explore Atipamezole \& caffeine's ability to facilitate the emergence from anesthesia. Each subject will visit UChicago 4 times. The first time for informed consent. The second time for a complete physical exam to ensure that the subjects are healthy. Then there are 2 sedation sessions. Subjects get an honorarium for each sedation session.
The goal of this clinical research study is to compare the effects of 4 quadrant TAP block (4Q-TAP block) with the standard-of-care thoracic epidural analgesia (TEA) in patients recovering from cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). A 4Q-TAP block is also known as an abdominal wall block and TEA is also known as a thoracic epidural. Both are types of anesthetics but are given in different ways. A 4Q-TAP block is when anesthetic injections are given in 4 different parts of the abdomen. A TEA is when an anesthetic injection is given in the space surrounding the spinal cord through your back. This is an investigational study. The surgery and the levels of anesthetic participant is receiving are standard-of-care. It is investigational to compare 4Q-TAP block with TEA. Up to 140 participants will be enrolled in this study. All will take part at MD Anderson.
Patient will have usual appendectomy surgery with an injection of local or saline at incision site either before or after the incision at random. The clinical hypothesis of this trial is that pediatric patients who undergo a local anesthetic pre-incisional and/or post-incisional will reduce the amount of postoperative pain and therefore reduce the amount of analgesics required to keep the patient satisfied. Primary: To determine if local anesthetic reduces postoperative pain. Secondary: To assess the timing of local anesthetic injection affects postoperative pain.
The purpose of this prospective, randomized, double-blinded, active-controlled study is: To assess the effectiveness of systemic administration of lidocaine and esmolol in combination (vs. either drug alone) will result in improved postoperative outcomes for patients undergoing abdominal surgery (e.g., less pain and postoperative constipation, nausea and vomiting, faster return of bowel function, resumption of normal activities of daily living), leading to a shorten length of hospital stay, maintaining hemodynamic stability during general anesthesia, when administered as intravenous adjuvants
This is a pharmacokinetic study to determine risk of local anesthetic systemic toxicity of ropivacaine when used in erector spinae plane blocks for thoracic surgery. Through serial blood sampling and the use of NONMEM population pharmacokinetic analysis this risk will be determined for the study population and other populations as well. Pain and quality of recovery will also be assessed.The erector spinae plane (ESP) block was first described in 2016 as a novel fascial plane block that provided analgesia for thoracic neuropathic pain. Since then hundreds of articles have been published that have reported use of the ESP block for indications such as rib fractures, breast surgery, abdominal surgery, and even shoulder surgery. It has also been studied in thoracic surgery and clinical experience confirms that patients undergoing video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracic surgery experience satisfactory analgesia with ESP blocks. Because the block location is further from the neuraxis than both epidural and paravertebral blocks, ESP blocks have been suggested as a safer alternative to these older blocks but safety data have not yet been generated. In particular, the risk of local anesthetic systemic toxicity (LAST) has not been studied in ESP blocks. While the pharmacokinetics of ropivacaine used for thoracic paravertebral blocks have been established, similar studies have yet to be performed for the newer ESP block. Of particular concern for ESP blocks are two factors not present in some other blocks with established safety: 1). significant intercostal spread has been noted in anatomical studies, which could put patients at risk for LAST and 2). some of the proposed dosing regimens involve the intermittent injection of large bolus doses of local anesthetic. While measurement of arterial plasma levels is useful and necessary to study the safety of ropivacaine given in ESP blocks, the measurements alone do not allow for prediction of plasma levels that would occur in populations as a whole. Nonmem is a population pharmacokinetic application that provides estimates of mean parameters and residual variability in pharmacokinetic values across populations and has been shown to generate better estimates than the two-stage approach. Nonmem will be used in this study to predict pharmacokinetics in populations with different characteristics than the one being studied here, which would create generalizable results.
This is a single-center, randomized, prospective study evaluating the effect of serratus anterior plane block performed after induction of anesthesia, but before the start of surgery on postoperative opioid requirements. The hypothesis of the study is that serratus anterior plane blocks are relatively simple to perform, provide good postoperative analgesia, facilitate early tracheal extubation, and reduce the length of hospital stay after pediatric cardiac surgery through a thoracotomy.
Morphine, when given as part of spinal anesthesia, is associated high incidence of nausea and pruritus, which may affect quality of recovery. The investigators hypothesize that long-acting local anesthetic infusions via TAP catheter can provide better quality of recovery after cesarean section than spinal morphine.
The purpose of this study is to determine if ultrasound-guided bilateral pectointercostal fascial plane blocks with bilateral rectus sheath blocks block decrease pain scores, decrease opioid consumption, improve respiratory function, and improve quality of recovery in patients recovering from elective cardiac surgery involving primary median sternotomy and mediastinal chest tubes in comparison to pectointercostal fascial plane blocks alone.
This study will recruit surgical patients more than 65 years old. Patients who participate will wear a sticker on their forehead during surgery which monitors their brain waves (electroencephalogram, EEG) and participate in memory testing before and after surgery. Brain wave patterns will be compared between patients who have problems with memory and thinking after surgery and those who do not. The hypothesis is that there will be characteristic brain wave patients for who will go on to have problems with memory and thinking after surgery.
