NCT ID: NCT05959135 Completed - Fasting Clinical Trials

Gastric Ultrasound in Diabetic and Non-Diabetic Pregnant Women

Start date: July 26, 2023
Phase:
Study type: Observational

Perioperative aspiration is particularly concerning in pregnant women due to anatomical changes. To mitigate this risk, pre-anesthetic fasting is recommended, with varying guidelines. Gastric ultrasound can non-invasively assess stomach contents, and mathematical models help estimate stomach volumes using the gastric antral cross-sectional area (CSA). This study aims to compare CSA and estimated gastric volumes through ultrasound in fasting diabetic and non-diabetic pregnant women scheduled for cesarean section, as diabetes may affect stomach fullness. Additionally, it will investigate the relation between demographic and clinical variables and CSA values. This research can shed light on diabetes' influence on aspiration risk in pregnancy and evaluate fasting guidelines, underscoring the significance of gastric ultrasound.

NCT ID: NCT05734937 Completed - Bleeding Clinical Trials

Ultrasound Evaluation of Gastric Volume in Pediatric Patients Undergoing Adenotonsillectomy Surgery

Start date: May 10, 2023
Phase: N/A
Study type: Interventional

Adenoidectomy and/or tonsillectomy are performed for many reasons such as recurrent tonsil and adenoid infections, sleep apnea, symptomatic adenotonsillar hypertrophy, halitosis, peritonsillar abscess, and it is one of the most performed surgeries in the world. Passive blood loss from the surgical field into the gastric area may occur during the surgery. Investigators wonder whether the amount of blood and fluid accumulated in the stomach after tonsillectomy and/or adenoidectomy in children will increase the risk of aspiration. For this purpose, the aim is to compare the results with values considered risky for aspiration by evaluating the pre- and postoperative gastric volume with ultrasound in children who underwent elective adenoidectomy and /or tonsillectomy.

NCT ID: NCT04875845 Completed - Ultrasonography Clinical Trials

Comparison of Gastric Volume After 6-hour and 8-hour Fasting in Patient Scheduled for Elective Surgery

Start date: January 1, 2019
Phase:
Study type: Observational

Preoperative fasting was a common practice to decrease perioperative aspiration risk. Duration of fasting was proportional to gastric volume. Short fasting duration may increase aspiration risk. However, prolonged perioperative fasting duration may lead to dehydration and hypoglycemia. The objective of this study was to analyze gastric volume after 6-hour and 8-hour duration of fasting after consumption of solid meal on patients scheduled for elective surgery. This was a cohort study recruiting 37 subjects from January to February 2019. Subjects were patients scheduled for elective non-digestive surgery in Cipto Mangunkusumo Hospital, Jakarta, Indonesia. Before fasting, all subjects consumed standard Cipto Mangunkusumo meal and was later assessed for gastric volume using ultrasound at 6 and 8 hour after meal was consumed.

NCT ID: NCT04819659 Completed - Anesthesia Clinical Trials

The Effect of Pharyngeal Packing on Postoperative Gastric Volume in Patients Undergoing Nasal Surgery

Start date: January 1, 2021
Phase: N/A
Study type: Interventional

Pharyngeal packing is a frequently used application to reduce the incidence and severity of postoperative nausea and vomiting (PONV) in patients who undergo nasal surgery. This study aims to research the effects of PP on gastric antral cross-sectional area (ACSA) and hence gastric volume as assessed by ultrasound, therewithal PONV and sore throat were evaluated as secondary outcomes in rhino logic surgeries (Septorhinoplasty, Septoplasty, Functional endoscopic sinus surgery).

NCT ID: NCT04181814 Completed - Clinical trials for Aspiration Pneumonia

Gastric Ultrasound for Preoperative Assessment of Gastric Content in Diabetic Patients

Start date: November 15, 2019
Phase:
Study type: Observational

ASA fasting guidelines are only applicable to healthy elective surgery patients. Measuring gastric volume now is not easy, and scintigraphy has remained the gold standard technique for many years. This prospective observational study aim to explore the gastric emptying of type 2 diabetic patients.

NCT ID: NCT04093726 Completed - Gastric Volume Clinical Trials

Lollipop on Gastric Volume

Start date: October 21, 2019
Phase: N/A
Study type: Interventional

To observe the effect of chewing lollipop on residual gastric volume in healthy volunteers with fasting.

NCT ID: NCT02852863 Completed - Gastric Volume Clinical Trials

Identification of Changes in Gastric Volume and Content by Ultrasound Before and After Chewing Gum

Start date: July 2016
Phase: N/A
Study type: Interventional

To identify by ultrasound the possible changes in gastric volume and content after chewing gum for an hour in volunteers with complete fasting (more than 8 hours).
