Active clinical trials for "Vomiting"

Nasogastric decompression was routinely used in most major intra-abdominal operations. Nasogastric tube intubation was thought to decrease postoperative ileus (nausea, vomiting, and gastric distension). Would and respiratory complications, and to reduce the incidence of anastomotic leaks after gastrointestinal surgery. However, the necessity of nasogastric decompression following elective abdominal surgery has been increasingly questioned over the last several years. Many clinical studies have suggested that this practice does not provide any benefit but could increase patient discomfort and respiratory complications. Furthermore, meta-analyses have concluded that routine nasogastric decompression is no longer warranted after elective abdominal surgery. Elective abdominal surgery without nasogastric decompression was initially tested and then widely used on patients with colorectal surgery.However, after upper gastrointestinal operations such as gastrectomy, nasogastric has been considered necessary to prevent the consequences of postoperative ileus (anastomotic leakage or leaking from the duodenal stump. Therefore, studies of gastrectomy without nasogastric tube emerged later than those of colectomy. In spite more and more studies reported of no need of nasogastric tube after abdominal operation, no papers reported after pancreaticoduodenectomy. Postulated causes of lack in studies to assess the need of a nasogastric tube after pancreaticoduodenectomy include anticipated prolonged postoperative paralytic ileus caused by PD-related extensive destruction and potential risk of gastric stasis after PD. However, our pilot study of retrospective analysis of postoperative NG drainage amount in 100 patients recently having PD at our hospital showed more than 90% of patients had less than 200cc/day NG drainage amount within postoperative day three. Theoretically, these patients might not need a nasogastric tube after pancreaticoduodenectomy. Therefore, investigators propose a prospective multicenter randomized trial to assess the need of a nasogastric tube after PD.

This study aims to evaluate the effect of intrapyloric botulinum toxin in children with feeding disorders.

Serotonin excretion was investigated in the nausea and vomiting associated with hiperemezis gravid arum.

We aimed to evaluate the different ETCO2 levels (with the help of ultrasonographic optic nerve sheath diameter) in preventing gynecological laparoscopic surgeons' postoperative nausea induced by intracranial pressure change due to pneumoperitoneum and trandelenburg position.

Proposed is a demonstration project to characterize the immediate, short-term and long-term pain and other post-operative outcomes of 60, self-selected breast (n=20), caesarian-section (n=20) and abdominal (n=20) surgical patients who receive opioid-sparing, multimodal anesthesia and pain management care as guided by the ComfortSafe Pyramid.

In this study we would like to identify demographic and individual risk factors that place parturients at a higher risk for postoperative nausea and vomiting (PONV) and itching following administered neuraxial morphine for cesarean section. Our primary objective is to develop a reliable predictive neuraxial morphine induced nausea and vomiting (NMINV) and itching model.

1. Background / Scientific Rationale The VEW (Vomiting, Eating, and Weight Loss) Questionnaire has been developed as a method for the assessment of post bariatric surgery patients, as well as a research tool into the eating behaviour of these patients. Objective VEW Questionnaire Premise If used optimally the VEW score is a valuable tool for patients who have had Laparoscopic Gastric Band Surgery (LAGB). The VEW score will be able to assist clinicians treating patients with a LAGB, specifically the Swedish Adjustable Gastric Band (SAGB), by providing them a tool to enhance patient outcomes. By using the information gained from the VEW questionnaire we can assess many areas of the eating behavior, and adjustment outcomes in patients with Gastric Bands. Hypotheses: The VEW questionnaire aids in the assessment of the need for gastric band adjustment (up or down in volume) Comparison of patient factors in those who have had a good outcome (increased weight loss) bad outcomes (vomiting, low weight loss, maladaption), from a gastric band fluid addition In patients who have had a bad outcome, which factors are more predictive? Fewer Complications associated with Gastric Band Adjustments Obstruction Need for urgent deflation Pain on eating Lowering incidence of inappropriate fills Lower incidence of maladaption Eating behavior can predict long term outcomes o By comparison of factors in the different quartiles of weight loss (particularly top 25% cf. bottom 25%) Maintenance of weight loss after 12 months is best achieved by use of behavior modification via improved food tolerances and better eating behavior than by increasing restriction of the band by further adjustments. 12 months is chosen as an arbitrary time where the majority of expected weight loss (45% of expected 50-55% 0f EWL) has been achieved. It is also a time frame by which patients have learnt to use the band appropriately, and the gastric band has had time to be adjusted into its optimal range. The VEW questionnaire can help predict poor outcomes from a SAGB adjustment. By analyzing the factors in patients who have returned both acutely (days) or at subsequent visits (weeks) and had fluid removed from their bands. These factors would include pain, vomiting, length of meals, maladaption score, fluid added, etc.

The purpose of this study is to provide oral domperidone to patients with gastroparesis, between the ages of 18 and 60 years of age, who have failed standard treatment. Standard therapy at the University of Iowa is eating blended foods, liquid diet, Eryped syrup (125 mg TID) 30 minutes before meals, or reglan (20 mg BID).

The primary objective is to test the hypothesis that the use of the Pressure Right device in combination with ondansetron and dexamethasone would result in a lower incidence of postoperative vomiting (emesis) than the combination of antiemetic therapy alone.
