Twilight sedation is, however, inherently safer than general anesthesia; it also allows the patients to follow simple commands and even to watch the procedure on a closed-circuit monitor. Tens of millions of adults annually need to have colonoscopies, and yet many dont because of concerns about the procedure.Colonoscopy can be carried out without any sedation and without problems with pain, which is practised in several institutions in many countries with the patients agreement. This allows the patient to shift the body position to help the doctor carry out the procedure and significantly reduces recovery time and side-effects. There is some discomfort when the colon is distended with air, but this is not usually particularly painful, and it passes relatively quickly. Unsedated patients can be released from the hospital on their own without any feelings of nausea, able to continue with normal activities, and without the need for an escort as recommended after sedation. Ultrasound
Duodenography and colonography are performed like a standard abdominal examination using B-mode and color flow Doppler ultrasonography using a low frequency transducer — for example a 2.5 MHz — and a high frequency transducer, for example a 7.5 MHz probe. Detailed examination of duodenal walls and folds, colonic walls and haustra was performed using a 7.5 MHz probe. Deeply located abdominal structures were examined using 2.5 MHz probe. All ultrasound examinations are performed after overnight fasting (for at least 16 hours) using standard scanning procedure. Subjects are examined with and without water contrast.
Anthrax immune globulin, tradename Anthrasil, is a human immune globulin that is used in combination with antibiotics to treat anthrax. It was developed by Cangene and purchased in 2011 by the Biomedical Advanced Research and Development Authority (BARDA) under Project Bioshield. On 24 March 2015 it was granted approval by the United States Food and Drug Administration for use in treating inhalation anthrax in conjunction with antibiotics. Preparation
Anthrax immune globulin is prepared from the plasma of donors who have been vaccinated against anthrax. Safety and efficacy testing
Due to the ethical and feasibility concerns with testing the efficacy of anthrax immune globulin in humans, it was tested in rabbits and monkeys under the FDAs animal efficacy rule. Following efficacy testing, anthrax immune globulin was tested for safety in human volunteers, where the most common side effects were headache, back pain, nausea and infusion site pain and swelling. == References ==
