Filter by:The study was planned to determine the effects of closed aspiration on arterial blood pressure, heart rate, respiratory rate, oxygen saturation level and pain in intensive care patients connected to mechanical ventilators. IThe effects of the closed aspiration system on hemodynamic parameters and pain will be determined and the results will be important in terms of the usability of the closed system in the clinical environment and raising awareness in nursing practices in order to create minimum complications for the patient.
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.
The aim of this study is to determine the effects of animation-based mobile application and simulation-based training methods on tracheal aspiration knowledge and skills of patient relatives who care for patients with tracheostomy/tracheotomy. Experimental pre-test-post-test control group study design was planned.
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.
Upper esophageal sphincter is a high pressure zone of the pharynx and protects airway from aspiration of esophageal or gastric contents. Existing literature concludes that many of the drugs employed to induce general anesthesia descend that pressure. However, most participants of those studies were under 64 years old and were given sedatives or local anesthetics to ease the esophageal measurements which can interfere with the results obtained. The hypothesis was to confirm the hypnotics effects on upper esophageal sphincter with the aim to find out which of them could be a better choice in order to reduce airway aspiration risk during induction of anesthesia, specially during emergency surgery, when a empty stomach is not guaranteed. Twenty patients who were planned for general surgery were studied: 12 men and 8 women, aged 39 to 84 years old. The effect of three commonly used hypnotics was tested: propofol, etomidate, and thiopental. Written informed consent was explained to all participants who freely signed it after having understood and accepted it. After 6-8 hours fast, patients were monitored with entropy (which gives information about patients´ level of consciousness), electrocardiogram, pulse oximetry (measures blood oxygen), and sphingomanometry (measures blood pressure). Registry of upper esophageal sphincter pressure was obtained through solid state high resolution manometry. A lubricated manometric probe was introduced through the nostril to locate it from the pharynx to the stomach using no sedation. After 1 minute to make the patient feel more comfortable, the induction of anesthesia took place employing one of the three drugs for this purpose mentioned above. Comparison of upper esophageal sphincter pressures before and after the hypnotic administration, should give information about which of the three hypnotics, if any, would not led to an unprotected airway and so at increased risk of aspiration.

This study seeks to determine if a relationship exists between gastric antrum cross-sectional area measured using ultrasound and BMI in term pregnant women (>37 weeks gestation).
Rationale: Seroma formation and its sequelae form the mainstay of complications in breast cancer surgery. Seroma has an incidence of 3% to 85%. Complications vary from delayed wound healing, infection, skin flap necrosis, patient discomfort and repeated visits to the out patient clinic. The key to reducing seroma formations seems to partly lie in the obliteration of dead space. The use of electrocautery has been demonstrated to increase seroma formation following mastectomy, however no other surgical devices (laser scalpel, argon diathermy and ultrasonic scalpel) or substances have proven to be superior in seroma reduction. No prospective randomized controlled trials have been able to demonstrate which techniques are superior in reducing seroma and as a consequence patient discomfort in patients undergoing mastectomy. In a previous retrospective observational study these investigators demonstrated that mastectomy flap fixation significantly reduced seroma formation and the number of seroma aspirations. In a pilot study that was recently performed in one of the investigators hospitals, ARTISS tissue glue was used for skin flap fixation and showed promising results. The investigators hypothesize that obliteration of the dead space following mastectomy will significantly reduce seroma formation, its complications and the discomfort it causes patients undergoing mastectomy.
