Filter by:This study is comparing total intravenous anesthesia with propofol with a regional nerve block against general anesthesia with a regional nerve block on the primary endpoint of time to meet discharge criteria.
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.
Airway management in severely obese patients remains a challenging issue for anesthetists and may lead to life-threatening situations. Awake Fiber-Optic Bronchoscopy Intubation (FOBI) technique is considered as the gold standard when a difficult airway is anticipated to secure the airway and to facilitate the surgery. FOBI is usually done in supine position, while (in conscious patients) lateral position is the most recommended position to keep the upper airway patent. This prospective clinical trial study will test whether awake FOBI in Lateral position will provide a safe profile or a significant advantage over FOBI in supine position, in morbidly obese patients undergoing elective bariatric surgery.
Edmon (BBraun, Germany) is a portable, commercially available device for measurement of propofol in exhaled air. The study will aim at evaluating the sensitivity and specificity of such exhaled propofol values compared with plasma propofol and measures of anaesthetic and antinociceptive effect.
Elderly people (EP) have increased, as well as life expectancy at birth. In Chile there are more than 2 million 800 thousand EP, which corresponds to 1/6 of the Chilean population. The EP have a higher disease burden and mortality when facing surgery and in the postoperative period. Thus, this population frequently has longer hospital stays due to its degree of fragility, surgical complications or decompensation of its underlying pathologies, directly affecting health care systems. An inadequate preparation of the EP prior to surgery determined that the requirements of in-hospital as well as out-of-hospital care are extended, with the consequent which entails a higher cost in health. Current research underestimates the conditions of frailty and dependence in the EP. In addition, it is not routinely evaluated prior to surgery, as well as nutritional, metabolic, cognitive status and / or delirium screening is performed. There are accelerated recovery programs, which relate their interventions to specific pathologies; however, the age of the person is not taken into account. Surgical pre-habilitation interventions in the EP usually focus their efforts on physical and cardiovascular aspects, not including an integrative pre-surgical evaluation. Based on the foregoing, a prospective, interventional, longitudinal and randomized study has been proposed in a population of the EP who will undergo elective urology and coloproctology surgeries in two university hospitals (private and public). The objective of this study is to evaluate how the implementation of a timely pre-surgical conditioning (APO) protocol for frail elderly people reduces the days of hospital stay. The APO considers the most relevant aspects of physical and cardiovascular pre-habilitation, in addition to contemplating evaluations of frailty, dependence, cognitive status, screening for delirium, nutritional and metabolic.
