Filter by:Gastric ultrasound has become increasingly utilized to examine volume and quality of gastric contents in the preoperative setting to guide anesthetic management and relay risk of aspiration in both adult and pediatric medicine. Gastric fluid volumes in trauma patients are thought to be elevated due to delayed gastric emptying in the setting of an over-attenuated sympathetic response to physical pain and stress, opioid analgesia, and other associated injuries (traumatic brain). However, there is a paucity of literature examining gastric fluid volumes (GFV), measured by gastric ultrasound, in the pediatric trauma population. The purpose of the study is to assess whether preoperative gastric ultrasound is an accurate method to identify pediatric trauma patients who have elevated GFV (>0.8mL/kg) and high-risk gastric contents (solids, complex liquids, in addition to large volumes).
Nearly half of critically ill children are intubated and enterally fed according to recent guidelines. However, no evidence-based recommendation are available regarding fasting times prior to extubation. When an extubation is planned, children do not always present with normal neurological status yet, and are at risk of vomiting and aspiration. Extubation may also fail and require re-intubation with similar risks. Thus, pre-operative fasting guidelines are often transposed to the paediatric critical care setting, aiming for an empty stomach at extubation, with perceived decreased risks of aspiration. However, the gastric and gut motility pathophysiology is significantly different in critically ill children (frequent gastroparesis, liquid continuous feeding, etc.) compared to planned surgery children. The extrapolation of practice validated in the latter population may be inadequate. The stomach may be empty more or less rapidly than expected, leading to unnecessary prolonged fasting times or inappropriately short fasting times respectively. Gastric ultrasounding monitoring may help assessing gastric content prior to extubation. Investigators hypothesise gastric content clearance may be different in critically ill children prior to extubation, compared to pre-operative paediatric guidelines for elective surgery.
The purpose of this study is to learn more about problems with swallowing that could develop in patients who are very sick and need a machine to help them breathe.
A prospective, multicenter, single-arm objective performance criteria trial to investigate the safety and efficacy of SINOMED ADPAT for Recanalization Therapy in acute large-vessel occlusive stroke.
The purpose of this study is to evaluate the use of early antibiotics in ICU patients who appear to have aspirated, to help determine whether this improves outcomes by reducing the later incidence of pneumonia and other negative consequences.
Our objective is to compare gastric volumes (mL) between women who receive metoclopramide versus placebo prior to scheduled cesarean delivery in appropriately fasted patients. If metoclopramide is found not to reduce gastric volumes this would inform future practice guidelines for obstetric anesthesia, which currently recommends metoclopramide administration prior to cesarean deliveries. We hypothesize that metoclopramide given to women with appropriate fasting prior to cesarean delivery does not result in any clinically significant reduction in gastric volume (mL) and therefore does not provide any additional benefit for aspiration prophylaxis but may expose patients to unnecessary side effects. A secondary objective will be to evaluate if gastric volume is a significant predictor of intraoperative nausea and vomiting.
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.
The investigator aimed to evaluate the effect of ultrasound guided esophageal pressure on the incidence of gastric insufflation during anesthetic induction in infants and small children undergoing general anesthesia.
This study will examine the effects of varying liquid viscosity on swallow physiology in infants with oropharyngeal dysphagia and brief resolved unexplained event (BRUE) and other children with dysphagia that would be at risk for symptoms of swallow dysfunction.
Cuff inflation up to the maximum cuff pressure when using LMA flexible can cause sore throat and discomfort after the surgery, and if the surgery is unexpectedly prolonged, there can be a side effect that can cause ischemic damage around the neck. If keeping cuff pressure low will not increase gastric insufflation and there is no change in other outcome variables, keeping it low may have a positive effect on anesthesia management and outcome in children.
