Filter by:This study aims to evaluate esmolol's perfusion impact during induction and maintenance of general anesthesia, using Nociception-Level-guided control of nociception, in adult patients undergoing laparoscopic and lower abdominal surgery, on intraoperative remifentanil consumption and postoperative pain in the Post-Anesthesia Care Unit.
This study aims to figure out how small-bore pigtail catheter or large-bore chest tube for postoperative drainage impact on analgesic efficacy and actually enhance recovery postoperatively.
Investigators will test, for safety and efficacy, a novel treatment for opiate addiction that applies a 4-minute treatment of intense near infra-red light to stimulate a side of the brain that the investigators determine to be healthier, more mature, and less traumatized. Investigators will compare among actively using participants an active and a sham treatment given either once or twice weekly for 25-weeks at 2 sites. Investigators hope this will lead to a significant weapon in the battle against the opioid epidemic as well as lead to psychological and physiological insights into possible relations among trauma, cerebral laterality, and addiction.
This is a study on how patients use and store opioid pain medications at home after surgery and what happens to left over pills when patients are done taking them. Participants will be taught the proper storage and destruction of opioid pain medications, then contacted in 6-8 weeks about pain medication used, stored disposed of.
The goal of this clinical trial is to compare Opioid Free and Opioid Based Anaesthesia in patients undergoing sleeve gastrectomy. The main questions it aims to answer are: - Will the total dose of intraoperative opioid be reduced? - Will there be difference in pain scores between groups? Participants will be managed with the Nociceptive Level Index algorithm to guide intraoperative analgesia. The Opioid Free Anaesthesia Group will be administered the Multimix infusion (Magnesium sulfate, dexmedetomidine, ketamine). The Opioid Based Anaesthesia Group will receive fentanyl as a bolus dose and remifentanil infusion. Rescue fentanyl bolused will be injected as appropriate according to nociceptive level (NOL) values.
The goal of this fundamental research study is to learn how opioids are incorporated into hair after application of opioids to newborns, infants and children in a controlled medical setting. The main questions aimed to answer are: Are opioids (specifically fentalogs) incorporated into hair? Are opioids detectable in sweat and does sweat influence the incorporation into hair? Can normative opioid value ranges be established in hair? Can these values help to for interpretation of opioid positive hair results and ultimately help distinguish between medical opioid intake and intake of illegal designer opioids? Hair samples from 150 patients will be taken as well as 75 sweat sample and analyzed for their opioid concentrations. Investigators hypothesize that opioids will be detectable in hair and sweat and that the cohort size will allow to establish normative value ranges that will help for interpretation of hair results in forensic toxicology.
Being relatively new, the NOL monitor may offer interesting observations in perioperative nociception levels and appropriate analgesic consumption in diverse surgeries, including robot-assisted surgery. These observations may supplement the current efforts towards further advantages in rapid restitution. Therefore, the investigators planned a trial where intra-operative analgesics were guided using an NOL monitor to study if intra-operative NOL guidance influences peri-operative analgesic consumption, postoperative length of stay and quality of recovery of patients subjected for robot-assisted surgery.
PCA morphine have been a common method in providing excellent analgesia for post-operative period. However, the usage of morphine is not without any side effects such as nausea, vomiting, respiratory depression, and over sedation. Many adjunct have been used in combination with morphine to observe the opioid sparing effects at the same time providing good analgesia. Dexmedetomidine is a potent and selective alpha-2 receptor agonist with sedative, anxiolytic, sympatholytic, and analgesic effects. As dexmedetomidine and morphine act via different mechanism, this combination produces synergistic analgesic effects. The objective of our study was to observe the effectiveness in pain relief between two low concentration of dexmedetomidine (2 mcg/ml versus 1 mcg/ml) as an adjunct to PCA morphine 1 mg/ml.
The purpose of this study is to determine whether administration of a pectoral nerve blocks (Pecs I and II) with 0.25% bupivacaine are more effective as compared to placebo to provide analgesia for cardiac implantable electronic device (CIED) placement in cardiac electrophysiology lab
The purpose of this study was to observe the effects of opioid-free anesthesia with S-ketamine on postoperative analgesia and perioperative hemodynamics in short surgical operations, and to explore the effects of S-ketamine on postoperative awakening time and extubation time, nausea and vomiting, hypoxemia, and delirium.
