This is a noninferiority study designed to examine whether conscious sedation with midazolam alone results in efficacy and safety that is not inferior to the combination of midazolam and fentanyl. English-speaking patients ≥18 years old and ≤75 years old presenting for GI endoscopy planned with conscious sedation using midazolam and fentanyl, will be randomized 1:1 to single agent sedation with midazolam or combination sedation with midazolam and fentanyl. Participants will be blinded to the choice of sedation. Sedation quality and adverse events will be measured with a validated patient-centered measure of procedural sedation quality, the PROcedural Sedation Assessment Survey (PROSAS) [Leffler, et al. Gastrointest Endosc. 2015;81(1):194-203]. Endoscopic quality measures in the 2 study groups will be collected by retrospective chart review, as an additional metric to ensure the quality of the procedure is not compromised by the choice of sedation.
the aim of the study is to assess the effect of intralipid as regard efficiency in decreasing myocardial ischemia , given during preconditioning in off pump coronary artery revascularization
Anorectal manometry requires that the patient be able to respond to command and not receive any medications which could alter muscle tone or motility. In the pediatric population, anorectal manometry can be psychologically challenging to parents and their child, as it is traditionally performed without adjuvant sedation or anesthesia. Sedatives and anesthesia can alter motility and smooth muscle activity, as well as render it difficult or impossible for the child to follow commands required of the study. Patient or parent non-compliance, inability to follow commands or to tolerate the procedure often renders the study invalid or impossible to complete. Dexmedetomidine is a sedative who's effect on anorectal musculature has not been studied nor determined. It would be important to determine whether it spares smooth muscle function, as it would provide a viable option to provide sedation to children while still preserving their ability to respond to command. The primary objective of this study is to examine the effects of dexmedetomidine on gastrointestinal smooth muscle by observing changes in anorectal manometry before and after dexmedetomdine administration.
There is scare literature about the usage of QLB in pediatric population, particularly the trans-incisional approach. Hence, the purpose of this study is to compare the postoperative analgesic efficacy of ultrasound-guided caudal epidural block versus ultrasound-guided QLB (trans-incisional) in combination with general anesthesia in pediatric patients undergoing elective open renal surgeries regarding pain scores, total analgesic consumption, and adverse effects.
A randomized double-blinded clinical trial was carried out on 40 patients undergoing knee arthroscopy. Patients were divided randomly into two equal groups. All drugs used were injected intra-articularly at the end of arthroscopy. In the control group, patients were administered 10mg morphine added to bupivacaine 25mg. In the study group, patients were administered 10mg morphine and 8mg dexamethasone added to bupivacaine 25mg. Visual analog score for pain at rest and movement, time to first analgesic request, total analgesic consumption, duration of analgesia and adverse effects were recorded.
50 million patients undergo surgery each year in the United States. Postoperative mortality is considered the third leading cause of death worldwide. Hypotension during surgery have been linked to increased postoperative morbidity and mortality. Episodes of hypotension during surgery are associated with an increased risk of acute kidney injury, stroke, cardiac events and death. Treating or preventing hypotension during general anesthesia and major surgery was found to improve outcomes. At this time, it is unclear what is the best vasopressor to maintain blood pressure during surgery under general anesthesia. With this pilot pragmatic trial, the investigators will explore the impact of norepinephrine (NE) or phenylephrine (PE) on post-operative events in patients undergoing major surgery with general anesthesia and needing vasopressors infusion to maintain their systemic arterial pressure.
Undergoing anesthesia requires patients to fast pre-operatively to allow the stomach to empty and prevent aspiration pneumonia but patients are allowed to drink "clear" liquids up to 2 hours before surgery. Clear liquids are defined as water, carbonated sodas, black coffee or tea without milk or sugar, and juices without pulp. Many Americans prefer to take their coffee with half and half or coffee creamer rather than black. This study will determine whether the addition of a small amount of cream to coffee makes any difference to the volume in the stomach after 2 hours. This study will use healthy volunteers as study participants. Each participant will participate in the study 3 times with at least 2 days in between. We will use a bedside ultrasound machine to measure their stomach content volume at baseline and then they will consume one of 3 different prepare drinks - black coffee, coffee with half and half, or coffee with non-dairy coffee creamer. After 2 hours, we will scan their stomach again and measure stomach content volume and compare it to the first measurement. The participants will repeat this two more times on different days so that they would have had a chance to consume all three prepared coffee drinks in a random order.
Fentanyl is one of the most common used opioids for analgesia during general anesthesia, however there are few studies that describe the relationship between its pharmacokinetics and pharmacodynamics, especially in the pediatric population. The monitoring of the analgesia component during general anesthesia has been traditionally by changes in patient's vital signs, with new devices that measure nociceptive indexes like the Nociception level (NoL) index currently being validated for adults. There is still lacking evidence with nociceptive indexes in the pediatric population. Insufficient dose of opioids may cause sympathetic response, respiratory complications, development of persistent post-surgical pain and even prolonged hospitalization. In the other hand, and overdose of opioids may cause over sedation, postoperatory nausea and vomiting, respiratory depression, hyperalgesia and tolerance. Given the lack of evidence on the Pharmacokinetic and pharmacodynamic (PK/PD) of fentanyl in this group of patients, has led to raise the development of this observational prospective study; which is to describe a PK/PD model of fentanyl in pediatric population, through evaluation of the NoL index, in patients submitted to elective general non-cardiac surgery.
The purpose of this study is to compare addition of dexamethasone to bupivacaine versus bupivacaine alone for trans-incisional bilateral paravertebral block for postoperative analgesia in elective lumbar spine surgeries.
