RATIONALE: Critical care ultrasound identifies the signs of free intraperitoneal air and echogenic free fluid always indicates hollow viscus perforation (HVP) and needs immediate surgical interventions. However, in rare cases, these classic signs may also mislead proper clinical decisions. We report perforated viscus associated large peritoneal effusion with initial critical care ultrasound findings, whereas computed tomography (CT) examination confirmed a giant stomach due to superior mesenteric artery syndrome (SMAS)...

Ultrasound assessment of gastric contents and volume is gaining popularity in adults and children. At present, a preoperative verbal check is used to determine the fasting status. Due to fear of delay or cancellation of surgery, parents may not disclose noncompliance with fasting guidelines. Pulmonary aspiration of gastric contents is a potential cause of morbidity and mortality. Ultrasound assessment of gastric contents is noninvasive and easy to learn. We present a series of three cases to demonstrate how the use of ultrasound to assess gastric contents in children can provide an objective means for decision-making and impact anesthetic management when preoperative fasting status is uncertain...

BACKGROUND: Pulmonary aspiration of gastric contents is associated with significant perioperative morbidity and mortality. Previous studies have investigated the validity, reliability, and possible clinical impact of gastric ultrasound for the assessment of gastric content at the bedside. In the present study, we examined the accuracy (evaluated as sensitivity, specificity, and likelihood ratios) of point-of-care gastric ultrasound to detect a "full stomach" in a simulated scenario of clinical equipoise...

OBJECTIVE: Feeding intolerance, manifesting as increased gastric residual, is a common finding in preterm neonates. Little is known about the regulation of gastric emptying early in life and the extent to which this plays a role in the preterm infants' feeding tolerance. The goal of this study was to evaluate clinically stable 28- to 32-week gestation neonates during the first 4 weeks of life and noninvasively determine their gastric emptying rate. STUDY DESIGN: Ultrasound measurements of gastric milk content volume were obtained from 25 neonates immediately after, 30 and/or 60 minutes following routine gavage feeds...

The effects of high intensity ultrasound (HIU) modification (power: 100-800 W, 15 min) on the conformation stability, in vitro digestibility and allergenicity of tropomyosin (TM) from Exopalaemon modestus were investigated. HIU treatment oxidized the Cys, Met and Lys in TM and degraded TM to generate protein fragments by HIU-induced free radicals. The α-helix content decreased, while β-sheet, β-turn and random coil increased. The immunoblotting and ELISA data suggested HIU treatment reduced the allergenicity and contributed to higher digestibility of TM...

BACKGROUND: Ultrasound examination of the gastric antrum allows reliable pre-operative assessment of gastric contents and volume in adult patients. However, during pregnancy, the change in the anatomical position of the stomach due to the gravid uterus leads to a change in the measured value of the antral area. Therefore, current mathematical models predicting gastric content volume (GCV) in the adult may not apply in term pregnant women. OBJECTIVE: To propose a mathematical model which is predictive of GCV in pregnant women and to assess the performance of an ultrasound qualitative grading scale (0 to 2) for the diagnosis of clear fluid volumes more than 0...

BACKGROUND: Intra-abdominal hypertension is a common complication in critically ill patients. Recently the Abdominal Compartment Society (WSACS) developed a medical management algorithm with a stepwise approach according to the evolution of the intra-abdominal pressure and aiming to keep IAP ≤ 15 mm Hg. With the increased use of ultrasound as a bedside modality in both emergency and critical care patients, we hypothesized that ultrasound could be used as an adjuvant point-of-care tool during IAH management...

BACKGROUND: Perioperative aspiration leads to significant morbidity and mortality. Standard fasting periods are used to ensure an empty stomach in patients. Anesthesiologists are frequently confronted with cases of dubious adherence to these guidelines. Point-of-care gastric ultrasound is a diagnostic tool that offers information on the type and volume of gastric contents. METHODS: We performed a retrospective analysis of a departmental database containing clinical and sonographic information on elective surgical patients who had been non- compliant to the fasting guidelines...

BACKGROUND: Gastric residuals are a common finding in enterally fed preterm neonates and traditionally thought to reflect immaturity-related delayed gastric emptying. Adult human data suggest that the meal volume regulate the gastric emptying rate, but early in life, this has not been adequately evaluated. The goal of this study was to study the rat postnatal changes in gastric emptying rate and the strain-induced effect on muscle contraction. We hypothesized that the stomach content volume and not developmental factors determines the newborn gastric emptying rate, via the Rho-kinase 2 (ROCK-2) pathway...

Adenocarcinoma stands the most common malignancies in the gastric carcinomas and holds a significant mortality and morbidity rates annually, due to the early vague symptoms among the population and hence the delayed presentation at advanced stages of cancer. In India the screening programs for gastric cancer has been a setback due to various logistics reasons and the data available from reporting is also not content. Our study is a review article featuring the management of gastric cancer in the Indian population...

Ultrasound examination of the gastric antrum allows reliable assessment of gastric contents and volume. Postoperative assessment of gastric contents before recovery from anaesthesia could help the physician to choose the most appropriate extubation technique after surgery in children. In this prospective observational study, we assessed whether significant changes occurred in gastric contents during the intra-operative period in children undergoing elective ear, nose and throat (ENT) surgery. Children aged between six months and 16 years were recruited consecutively...

INTRODUCTION: Pulmonary aspiration of gastric contents in pregnant women undergoing general anesthesia or sedation/analgesia in the peripartum period is a feared complication in obstetric anesthesia. We assessed the changes in antral cross-sectional area (CSA) with ultrasonography in laboring women and in the immediate postpartum period. PATIENTS AND METHODS: In an observational study in a university-affiliated maternity, gastric ultrasonography examinations were performed in non-consecutive laboring women, after epidural analgesia insertion and after childbirth...

BACKGROUND: Cricoid pressure during intubation has been used for decades as a way to potentially occlude the esophagus to avoid aspiration of gastric contents. However, recent evidence has questioned the effectiveness of this maneuver. OBJECTIVE: This study uses a noninvasive modality, ultrasonography, to determine the anatomic position of the cricoid cartilage and the esophagus and examines the effectiveness of cricoid pressure on esophageal compression. METHODS: Ultrasound imaging was used to describe the anatomic relationship of the esophagus to the trachea as either being directly behind the trachea, partially behind the trachea, or completely lateral to the trachea...

Objective: Pulmonary aspiration of the gastric contents is one of the most feared complications in anesthesia. Its prevention depends on preoperative fasting as well as identification of risky patients. A reliable diagnostic tool to assess gastric volume is currently lacking. The aim of this study performed on volunteers was to evaluate the feasibility of ultrasonography to identify qualitative and quantitative gastric content. Method: A standardized gastric scanning protocol was applied on 67 healthy volunteers to assess the gastric antrum in four different situations: fasting, after ingesting clear fluid, milk and a solid meal...

This prospective study was designed to evaluate gastric volume and content in patients with renal failure and healthy controls after an overnight fast, immediately after a light meal and at 6 h after the meal. Thirty subjects in each group were recruited. At each scanning session, gastric antral cross-sectional area was measured in the supine recumbent and right lateral decubitus positions, and a qualitative assessment of gastric contents was made using the Perlas three-point grading system. Six hours after the meal, the mean (SD) antral cross-sectional area in the supine position was 471 (195) mm(2) in patients with renal failure and 319 (106) mm(2) in healthy controls (p = 0...

BACKGROUND: Point-of-care gastric ultrasound is an emerging tool to assess gastric content and volume at the bedside. The examination includes both a qualitative and a quantitative component. The aim of this study was to evaluate the performance of an existing model for predicting gastric volume in severely obese subjects (BMI >35 kg m-2 ). METHODS: This observer-blinded experimental study compared the gastric volume predicted based on a sonographically measured cross-sectional area of the gastric antrum with the gastric volume measured by suctioning under gastroscopic guidance in a cohort of severely obese subjects...

We report two cases of patients presenting for elective surgery, in whom significant gastric contents were identified by performing fortuitous ultrasound examination of their antral area. The first patient presented for a day-case surgery scheduled under regional anesthesia. With his consent, ultrasound examination of the antral area was by chance performed within the context of training for this technique, showing significant solid contents in the stomach. The patient admitted that he had not respected preoperative fasting...

BACKGROUND AND OBJECTIVES: The current preoperative fasting guidelines allow fluid intake up to 2hours before surgery. The aim of this study was to evaluate the gastric volume of volunteers after an overnight fast and compare it with the gastric volume 2hours after ingestion of 200 and 500mL of isotonic solution, by means of ultrasound assessment. METHOD: Eighty volunteers underwent gastric ultrasound at three times: after 8hours of fasting; 2hours after ingestion of 200mL isotonic saline, followed by the first scan; and on another day, 2hours after ingestion of 500mL of the same solution after an overnight fast...

BACKGROUND & AIMS: We previously demonstrated that the gastric emptying rate of liquids chiefly depended on the total amount of calories (energy content) in a uniform volume. The aim of the present study was to examine the effects of different volumes of liquids with a uniform energy content on gastric emptying. METHODS: Three types of test solutions were prepared with a uniform amount of calories (200 kcal provided by glucose) and step-wise increments in volume (200 ml, 400 ml, and 600 ml)...
