The word autism first took its modern sense in German, when Asperger adopted Bleulers terminology autistic psychopaths in a 1938 lecture in German about child psychology. Asperger was investigating an ASD which was later known as Asperger syndrome, although it did not become widely recognized as a separate diagnosis until 1981. In English, Kanner first used autism in its modern sense when he introduced the label early infantile autism in a 1943 report of 11 children with striking behavioral similarities. Almost all the characteristics described in Kanners first paper on the subject, notably "autistic aloneness" and "insistence on sameness", are still regarded as typical of the autistic spectrum of disorders. It is not known whether Kanner derived the term independently of Asperger.Kanners reuse of autism led to decades of confused terminology like infantile schizophrenia, and child psychiatrys focus on maternal deprivation led to misconceptions of autism as an infants response to "refrigerator mothers". Starting in the late 1960s, autism was established as a separate syndrome. However, Kanner was the first person to describe ASD as a neurodevelopmental disorder in 1943 by calling it infantile autism and therefore rejected the refrigerator mother theory.The discussion of autism prior to the twentieth century is one that brings about much controversy. Without researchers being able to meet a consensus on the varying forms around the condition, there was a lack of research being conducted on the disorder. Discussing the syndrome and its complexity frustrated researchers. Controversies have surrounded various claims regarding the etiology of ASDs.
Newborns
Syndromes such as respiratory distress syndrome, congenital heart disease, pneumothorax, and shock may lead to breathing problems in newborn infants that require endotracheal intubation and mechanically assisted breathing (mechanical ventilation). Newborn infants may also require endotracheal intubation during surgery while under general anaesthesia. Equipment
Laryngoscopes
The vast majority of tracheal intubations involve the use of a viewing instrument of one type or another. The modern conventional laryngoscope consists of a handle containing batteries that power a light and a set of interchangeable blades, which are either straight or curved. This device is designed to allow the laryngoscopist to directly view the larynx. Due to the widespread availability of such devices, the technique of blind intubation of the trachea is rarely practiced today, although it may still be useful in certain emergency situations, such as natural or man-made disasters. In the prehospital emergency setting, digital intubation may be necessitated if the patient is in a position that makes direct laryngoscopy impossible. For example, digital intubation may be used by a paramedic if the patient is entrapped in an inverted position in a vehicle after a motor vehicle collision with a prolonged extrication time. The decision to use a straight or curved laryngoscope blade depends partly on the specific anatomical features of the airway, and partly on the personal experience and preference of the laryngoscopist. The Macintosh blade is the most widely used curved laryngoscope blade, while the Miller blade is the most popular style of straight blade.
