It can also be administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI). Propofol is also used to sedate individuals who are receiving mechanical ventilation but not undergoing surgery, such as patients in the intensive care unit. In critically ill patients, propofol is superior to lorazepam both in effectiveness and overall cost. Propofol is relatively inexpensive compared to medications of similar use due to shorter ICU stay length. One of the reasons propofol is thought to be more effective (although it has a longer half-life than lorazepam) is because studies have found that benzodiazepines like midazolam and lorazepam tend to accumulate in critically ill patients, prolonging sedation. Propofol has also been suggested as a sleep aid in critically ill adults in the ICU; however, the effectiveness of this medicine at replicating the mental and physical aspects of sleep for people in the ICU is not clear.Propofol can be run through a peripheral IV or central line. Propofol is frequently paired with fentanyl (for pain relief) in intubated and sedated people. The two drugs are compatible in IV form. Procedural sedation
Propofol is safe and effective for gastrointestinal endoscopy procedures. Its use in these settings results in a faster recovery compared to midazolam. It can also be combined with opioids or benzodiazepines. Because of its rapid induction and recovery time, propofol is also widely used for sedation of infants and children undergoing MRI.
Late congenital syphilitic oculopathy is a disease of the eye, a manifestation of late congenital syphilis. It can appear as:

Interstitial keratitis – this commonly appears between ages 6 and 12. Symptoms include lacrimation and photophobia. Pathological vascularization of the cornea cause it to turn pink or salmon colored. 90% of cases affect both eyes. Episcleritis or scleritis – nodules appear in or overlying the sclera (white of eye)
Iritis or iris papules – vascular infiltration of the iris causes rosy color change and yellow/red nodules. Chorioretinitis, papillitis, retinal vasculitis – retinal changes can resemble retinitis pigmentosa. Exudative retinal detachmentCongenital syphilis is categorized by the age of the child. Early congenital syphilis occurs in children under 2 years old, and late congenital syphilis in children at or greater than 2 years old. Manifestations of late congenital syphilis are similar to those of secondary syphilis and tertiary syphilis in adults. References
