TIVA may be favoured as the anesthetic technique of choice for the following reasons ADVANTAGES OF TIVA: 1. Rapid smooth induction and maintenance of anesthesia Induction of anesthesia with propofol is smooth and associated with a low incidence of excitatory side effects. Doses of 1 to 2.5 mg/kg (depending on patient age, physical status, and use of premedicant drugs) induce anesthesia in approximately 30 seconds. The speed of onset and the dose of propofol needed for induction are dependent on the

Everyone uses inventions every single day. This goes from the lights on your ceiling, to your phone you use to text and call others, to phonographs for you to listen to. An inventor, Thomas Edison, made many inventions that you still use today. Although he died a long time ago, he still affects society in the past and in the present. His inventions led him to popularity, and soon enough, a hero of society. Heroes are people who try to help society by doing or saying something in a beneficial way

of a 4-year-old female that presents with a two-day history of nasal congestion and an early morning cough. The parent states that the child is afebrile with a normal appetite and sleeping pattern. However, she states that Kaitlyn has thick green nasal drainage. Upon physical examination, lungs are clear to auscultation, tympanic membranes are pearly gray without fluid, and no cervical adenopathy. Although the individual?s nasal turbinates are red, and, she has clear rhinorrhea and postnasal

INTRODUCTION Epidemiology Soil-transmitted helminth infections are gotten through contact with soil contaminated with infected feces. STH infections were once common throughout the world, including the United States, and some occurrence are still seen in the U.S. each year. With proper sanitation, these infections are now common only in poorer countries. More than four billion people are at high risk throughout the world, with over one billion individuals already infected. The greatest numbers

slides that discussed the flu vaccine. The comments centered on the audience not being able to follow when vaccination options (injection, nasal spray, intradermal) were explained, but were not presented on any slides. One stated that they did not quite understand what an “inactivated virus” was, referring to the flu shot. Two adults were not aware of the nasal spray option and, other than what was shared on the slides, presenter was unable to answer further questions with regard to contraindications

Great Nursing Shoes Let’s face it, nurses have a tough job. They are constantly on their feet for long hours and need shoes that will support them every step they take. Our page is designed to equip you with the necessary information to buy the shoes best suited for you. No matter what level your career is in, a good pair of shoes is a requirement. A good pair of nursing shoes can be quite expensive and like any other major purchase you make; you should never buy anything without doing some research

Ectopia Cordis is a rare condition in which the heart is located partially or completely outside of the thoracic cavity. Often, it is associated with pentalogy of Carntrell, which is a rare thoraco-abdominal disruption or a defect in the abdominal wall. This condition is categorized into five types: cervical, abdominal, thoracocervical, thoracoabdominal, and thoracic. Ectopia cordis is extremely uncommon as it only occurs in 1:126,000 births. The prognosis for this condition is poor and depends

When you hear the term “Hero”, you often imagine a person with a cape flying across town, a person with superpowers fighting unusual looking monsters to help keep your community safe. As a child or even at an older age, you’re asked about one person that you admire. You may look up to that particular person because of the journey they have decided to take. You follow in their footsteps, because they’ve showed you who they were, who they wanted to become, and who they became. I never considered myself

An ideal member of the National Honor Society must demonstrate the following characteristics: Leadership, Service, and Character. To qualify for such a prestigious organization, one must qualify with a GPA of at least 3.5. Academically, I have been able to do so, maintaining a cumulative GPA of 4.11 and yet to receive an overall grade below A- in these past three semesters of High School. Moreover, I have been taking two languages, Malay and French, as well as juggling advanced classes such as Integrated

of the nose) in a nose, is a procedure done by an Otolaryngologist (ear, nose, and throat doctor) for both medical and physical appearance reasons. For medical reasons, Septoplasty is done on patients with a deviated or crooked septum to open their nasal canals for better olfaction (smell) and ultimately an enhancement in respiration (breathing). This procedure is oftentimes a successful procedure for patients; however, there are potential, negative effects that patients should be aware of before braving

INTRODUCTION Nasal lobular haemangioma is a rare benign tumour of the Sino nasal tract 1. The exact aetiology of this condition is unknown. Though Head and Neck is the most common location of these tumours, involvement of Sino nasal tract is very rare. The most common sites of these tumours are gingiva, lips and tongue. These are rapidly growing hyper vascular lesions. The clinical features, radiological features and pathological findings are described in Manuscript Click here to download Manuscript:

3- Pharynx (throat): Pharynx is a muscular tube which function is to connect posterior end of the nasal cavity and to the superior end of the esophagus and larynx. Anatomically pharynx is divided into: Nasopharynx: posterior of the nasal cavity, and it receives air that is inhaled by the nasal cavity. Oropharynx: posterior of the oral cavity, and it receives air that is inhaled by oral cavity. Laryngopharynx: the end of pharynx, when the air reaches laryngopharynx the air will be diverted to the

skills. The lacrimal drainage system anatomy can be discussed under following components: 1. Embryology 2. Osteology 3. Nasal and paranasal sinuses 4. Secretory system 5. Excretory system Embryology Familiarity with lacrimal system embryology is necessary to understand congenital abnormalities of the nasolacrimal drainage system. Secrtory

The oral cavity is one of the three major resonators also including the nasal cavity and the pharyngeal cavity. The velopharyngeal port decides what resonating cavity, the nasal or the oral, the airflow will travel through. For example, there are three nasal sounds, the /m/, /n/, and the /ng/ sound. When these sounds are being produced, the velopharyngeal port closes forcing the air to go to the nasal cavity. Some sounds require both the nasal and the oral cavity. Sounds that vibrate

Nasal intubation is a commonly practiced airway management technique in oral and maxillofacial surgeries. Complications can occur at different levels during intubation through the nasal passage such as haemorrhage, turbinectomy and many cases reported even during extubation. This article describes a case of difficult extubation of naso-tracheal tube caused by the cuff inflation channel (pilot tube) encircling the inferior turbinate and logding between the turbinates. To our literary knowledge; no

DEFINITION OF NASAL POLYP. The word Polyp is originally Greek and has undergone Latinization and means Polypous that is many footed.35 The term Polyp mentions to the macroscopic appearance of a pedicled tissue arising from a mucosal surface and projecting into lumen or cavity.26 Hence Nasal polyps are defined as pearly white painless prolapsed pedunculated parts of nasal mucosa.35 PATHOLOGY OF NASAL POLYPS. Macroscopically Polyps have an edematous smooth and shiny appearance with a soft consistency

the nasal depression and the mouth to the larynx and throat. The pharynx dividers are skeletal muscles. The pharynx is at the base of the skull down to the sixth cervical vertebra. The structure of the pharynx helps when playing O2 touch, as we take full breaths amid activity, air experiences in mouth increasingly and afterward goes to the lungs to be transported to the muscles. Nasal depression The nose is the main outer part of the respiratory framework and the inner part is the nasal depression

Deviated Septum Your septum is the wall of cartilage inside your nose that separates the hollow space (nasal cavity) between your nostrils. Normally the septum is straight. It divides the nasal cavity into two parts. A deviated septum means this wall is not in the center of the nasal cavity. A deviated septum can lead to stuffiness and other problems with the flow of air through your nose. It can also block your sinuses and keep them from draining properly. This can lead to repeated (chronic) sinus

1.The Palatine Bone 1.1Definition: The palatine bone is a paired, L-shaped bone of facial skeleton that is situated at the back part of the nasal cavity between the maxilla and the pterygoid process of the sphenoid, It contributes to the walls of three cavities: the floor and lateral wall of the nasal cavity, the roof of the mouth, and the floor of the orbit; it enters into the formation of two fosse, the pterygopalatine and pterygoid fosse; and one fissure, the inferior orbital fissure (Gray

where air passes and mucus drains. We have eight sinus cavities in total. They are paired on equal sides of our face, resulting in four pairs of sinus cavities. Each cavity has an opening called an ostium, leading to the nasal passages to exchange for air and mucus. The mucus linings have cells with fine hairs called ciliated epithelium that moves dirty mucus from the sinus cavities down the nasal passages. Our four pairs of sinus cavities are: • Ethmoid sinuses. These sinuses are located between
