Another key feature of RSI is the application of manual cricoid pressure to the cricoid cartilage, often referred to as the "Sellick maneuver", prior to instrumentation of the airway and intubation of the trachea.Named for British anesthetist Brian Arthur Sellick (1918–1996) who first described the procedure in 1961, the goal of cricoid pressure is to minimize the possibility of regurgitation and pulmonary aspiration of gastric contents. Cricoid pressure has been widely used during RSI for nearly fifty years, despite a lack of compelling evidence to support this practice. The initial article by Sellick was based on a small sample size at a time when high tidal volumes, head-down positioning and barbiturate anesthesia were the rule. Beginning around 2000, a significant body of evidence has accumulated which questions the effectiveness of cricoid pressure. The application of cricoid pressure may in fact displace the esophagus laterally instead of compressing it as described by Sellick. Cricoid pressure may also compress the glottis, which can obstruct the view of the laryngoscopist and actually cause a delay in securing the airway.Cricoid pressure is often confused with the "BURP" (Backwards Upwards Rightwards Pressure) maneuver. While both of these involve digital pressure to the anterior aspect (front) of the laryngeal apparatus, the purpose of the latter is to improve the view of the glottis during laryngoscopy and tracheal intubation, rather than to prevent regurgitation.
Proctocolitis is a general term for inflammation of the rectum and colon. Signs and symptoms
Cause
Proctocolitis has many possible causes. Common infectious causes of proctocolitis include Chlamydia trachomatis, LGV (Lymphogranuloma venereum), Neisseria gonorrhoeae, HSV, and Helicobacter species. It can also be idiopathic (see colitis), vascular (as in ischemic colitis), or autoimmune (as in inflammatory bowel disease). Diagnosis
Anoscopy can be used to diagnose the majority of cases of proctocolitis. Treatment
Antibiotics, such as ceftriaxone and doxycycline, if there is  infection
