We report about detailed hemodynamic changes and one major cardiac complication occurring after submucosal injection of epinephrine (1 : 10 000) for management of upper gastrointestinal bleeding in a series of four consecutive patients. Cardiac contractility and afterload, determined by the cardiac index and the systemic vascular resistence index (SVRI), were assessed by transpulmonary thermodilution using the Pulse Contour Cardiac Output monitoring system (PiCCO; Pulsion Medical Systems, Munich, Germany), and the mean arterial pressure and heart rate were recorded. We observed a distinct rise in both mean arterial pressure and heart rate, and this effect was pronounced in the three patients with esophageal lesions. ⋯ In conclusion, submucosal injection of epinephrine may cause significant hemodynamic changes that can potentially lead to adverse cardiac events. Close cardiac monitoring during and after submucosal application of epinephrine therefore seems a prudent precaution. In the treatment of esophageal lesions, the total amount of epinephrine injected should be carefully titrated, so that the lowest possible volume that achieves adequate hemostasis is used.

Abdominal pain related to pancreatic cancer or chronic pancreatitis can be a disabling and difficult symptom to treat for patients, their families, and physicians. Pharmacologic therapy with nonsteroidal anti-inflammatory drugs is usually ineffective. Opiate analgesics may not be well tolerated and can lead to dependence. Endoscopic ultrasound-guided celiac plexus block offers a potential adjunct treatment for pain control.

Recent studies have documented the safety of propofol sedation for endoscopic procedures, but many endoscopists are reluctant to use propofol for high-risk patients because of adverse effects. The aim of this study was to demonstrate the safety and efficacy of nurse-administered propofol sedation during emergency upper endoscopy for patients with gastrointestinal bleeding. ⋯ Using a strict protocol designed to protect the patient's airway and cardiovascular function, nurse-administered propofol sedation during emergency upper gastrointestinal endoscopy is safe and appropriate in cases of acute gastrointestinal bleeding.

Randomized Controlled Trial
Quality of psychomotor recovery after propofol sedation for routine endoscopy: a randomized and controlled study.
Propofol sedation is increasingly being used for endoscopy in the outpatient setting. In view of the agent's short period of action, current recommendations that patients should avoid driving or using public transport unescorted for 24 h may be too strict. Psychomotor recovery and driving skills before and after sedation were therefore assessed. ⋯ Current recommendations that patients should refrain from driving and unescorted use of public transport for 24 h after sedation may need to be reconsidered in patients who receive propofol sedation.
