Composition of the extracellular matrix in human cricoarytenoid joint articular cartilage. (1/82)

The extracellular matrix of the human cricoarytenoid joint articular cartilage is involved in different pathological changes. Interestingly, in contrast to the limb joints, the extracellular matrix composition of the healthy cricoarytenoid joint articular cartilage has not yet been elucidated except by some light microscopical investigations. The present study investigates the extracellular matrix components of the cricoarytenoid joint articular cartilage by means of light microscopy, immunohistochemistry, transmission electron microscopy and scanning electron microscopy and compares them with the limb joints for a better understanding of their involvement in joint disease. Chondrocytes near the joint surface of the cricoid and arytenoid cartilage differ from chondrocytes of deeper cartilage layers. The extracellular matrix of the articular cartilage contains chondroitin-4-sulfate, chondroitin-6-sulfate and keratansulfate as well as collagen types II, III, VI, IX and XI. Type-III-collagen shows a special distribution throughout the joint cartilage. In deeper cartilage layers, type-III-collagen occurs only pericellularly; in higher cartilage layers type-III-collagen is also located territorially and interterritorialy in small amounts. Scanning and transmission electron microscopy have revealed the articular surface of the cricoid and arytenoid cartilage to consist of a network of irregularly organized collagen fibrils, which are lined by a layer of electron dense material. The network coats subjacent collagen bundles which descend obliquely downward and intermingle at right angles in the middle part of the articular cartilage with collagen bundles of the deeper cartilage zones. The articular cartilage surface shows structural characteristics which differ from the underlying cartilage. The superficial electron dense layer possibly plays a role in the lubrication of the articular cartilage surface. The alignment of the fibrillar structures in the articular cartilage of the cricoarytenoid joint varies from those of the limb joints based on the different strain occurring during arytenoid movement. Nevertheless, the human cricoarytenoid joint articular cartilage can be compared with the joints of the limbs despite its extracellular matrix composition and its involvement in joint pathology. Evidence of type III collagen in the outermost layer of the articular cartilage of the cricoarytenoid joint presents a peculiarity, which has yet not be demonstrated in the articular cartilage of limb joints.  (+info)

New insights into the pathomechanism of postintubation arytenoid subluxation. (2/82)

BACKGROUND: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament can occur as a consequence of endotracheal intubation. The biomechanics and pathomechanism of cricoarytenoid subluxation have not been demonstrated to date. METHODS: The present study attempts to simulate the trauma that has been associated with arytenoid cartilage subluxation in intubation trials on 37 unfixed larynges in cadavers from persons aged 25 to 89 years. Larynges were intubated or extubated according to former conceptions of arytenoid subluxation, which assume that the arytenoid tip enters the lumen of the tracheal tube, or that a deflection of the arytenoid occurs during withdrawal of the endotracheal tube with the cuff of the tube only partially deflated. Also, manual attempts were carried out to subluxate the arytenoid cartilage. Subsequently after dissecting the left and right cricoarytenoid joint from each larynx, the morphologic changes induced experimentally were analyzed using gross microscopic and histologic methods. RESULTS: Within the scope of the experiment, it proved impossible to produce any subluxation of a cricoarytenoid joint. Histologic analysis revealed injuries of synovial folds, joint-surface impressions of the articular cartilage, and fractures in the area of the subchondral bone in some joints. CONCLUSIONS: Based on the morphologic results, it was concluded that intubation trauma of the cricoarytenoid joint does not cause subluxation per se, but rather that formation of a hemarthros or fractures of the joint bodies lead to fixation of the joint surfaces in an abnormal position. Subsequent ankylosis may occur.  (+info)

Gastric pressure during emergency caesarean section under general anaesthesia. (3/82)

Gastric pressure and volume were measured in 20 pregnant women during emergency Caesarean section under general anaesthesia with neuromuscular block. Mean gastric pressure was 11 (range 4-19) mm Hg and we can predict that 99% of women undergoing emergency Caesarean section with neuromuscular block are likely to have gastric pressures of less than 25 mm Hg (mean + 3 SD). This has implications for the amount of cricoid pressure required during induction of anaesthesia. Gastric pressure increased during delivery to 19 mm Hg and fundal pressure caused a gastric pressure of 65 mm Hg in one woman. Gastric pressure decreased significantly after delivery (P < 0.001) to 8 mm Hg. Although we measured large gastric volumes (mean 112 (range 20-350) ml), there was no correlation between gastric volume and gastric pressure.  (+info)

Osteoarthritis in cricoarytenoid joint. (4/82)

OBJECTIVE: Occurrence of osteoarthritis is a frequent event of limb joints in people over 40 years of age. The human cricoarytenoid joint is comparable with the joints of the limbs despite its structure and extracellular matrix composition. To date, little is known about the occurrence of osteoarthritis in the human cricoarytenoid joint. METHODS: Sixty-eight cricoarytenoid joints (42 male and 26 female, age 25-98 years) were analysed by means of histology, lectin histochemistry, immunohistochemistry as well as scanning and transmission electron microscopy. RESULTS: About 50% of the investigated cricoarytenoid joints aged over 40 years show degenerative changes in their joint surface structure at varying levels of intensity. The articular cartilage surface is fibrillated in some places and sometimes shows fissures. A demascing of collagen fibrils next to the joint surface and a loss of proteoglycans in the upper cartilage layers can be observed. Chondrocytes near the joint surface appear as voluminous chondrocyte clusters. The clusters and the superficial cartilage layer show a positive reaction to type VI collagen antibodies. The distribution patterns of lectins are completely changed in fibrillated cartilage areas. CONCLUSION: Degenerative alterations in diarthrodial joints resembling osteoarthritis can occur in the joints of the larynx. These structural changes of the articular cartilage are comparable to osteoarthritis of the limb joints. Osteoarthritis in the cricoarytenoid joint may lead to impaired movements of the arytenoid cartilages. Functionally the structural changes may lead to negative consequences during vocal production, such as impaired vocal quality and reduced vocal intensity.  (+info)

Effect of cricoid pressure on insertion of and ventilation through the cuffed oropharyngeal airway. (5/82)

We have assessed the effect of cricoid pressure on insertion of and ventilation through the cuffed oropharyngeal airway (COPA) in 53 patients, in a double-blind, randomized study. Two anaesthetists assessed adequacy of ventilation in anaesthetized and paralysed patients at the same time but using different methods. The first assessed ventilation clinically, by observing synchronized chest expansion with gentle manual ventilation and the second noted measurements of tidal volume (VT) and peak inspiratory pressure (PIP). Five mask ventilated breaths ('baseline') were assessed as above. Patients were then allocated randomly to receive cricoid pressure (group A, n = 28) or no cricoid pressure (group B, n = 25). Five further mask ventilated breaths ('after manoeuvre') were again assessed. A COPA was then inserted and five further breaths ('after COPA') were assessed. A COPA was inserted at the first attempt in all patients except for one in group A who required two attempts. COPA placement was difficult in one patient in group B who had a small distance between the incisor teeth. Ventilation was clinically 'adequate' in all patients except for one in the cricoid pressure group. There were no significant differences in measured VT or PIP between 'baseline' and 'after manoeuvre' breaths. Significant differences in VT and PIP were found after COPA insertion in the group that received cricoid pressure, with a mean decrease in VT of 108 ml (P = 0.0049) and a mean increase in PIP of 5.2 cm H2O (P = 0.0111).  (+info)

Competence of the internal jugular vein valve is damaged by cannulation and catheterization of the internal jugular vein. (6/82)

BACKGROUND: Experimental results suggest that the competence of the internal jugular vein (IJV) valve may be damaged when the IJV is cannulated for insertion of a central venous catheter. It has further been hypothesized that the risk of causing incompetence of the proximally located valve might be reduced by using a more distal site for venous cannulation. The present study evaluated these hypotheses in surgical patients. METHODS: Ninety-one patients without preexisting incompetence of the IJV valve were randomly assigned to undergo distal or proximal IJV cannulation (> or = 1 cm above or below the cricoid level, respectively). Color Doppler ultrasound was used to study whether new valvular incompetence was present during Valsalva maneuvers after insertion of a central venous catheter, immediately after removal of the catheter, and, in a subset of patients, several months after catheter removal, when compared with baseline findings before cannulation of the IJV. RESULTS: Incompetence of the IJV valve was frequently induced both by proximal and distal cannulation and catheterization of the IJV. Its incidence was higher after proximal than after distal cannulation (76% vs. 41%; P < 0.01) and tended to be so after removal of the catheter (47% vs. 28%; P = 0.07). Valvular incompetence persisting immediately after removal of the catheter did not recover within 8-27 months in most cases. CONCLUSIONS: Cannulation and catheterization of the IJV may cause persistent incompetence of the IJV valve. Choosing a more distal site for venous cannulation may slightly lower the risk of causing valvular incompetence but does not reliably avoid it.  (+info)

Cricoid pressure applied after placement of laryngeal mask impedes subsequent fibreoptic tracheal intubation through mask. (8/82)

We studied 70 patients to see if cricoid pressure applied after insertion of the laryngeal mask altered the success rate of tracheal intubation through the mask. After induction of anaesthesia and neuromuscular blockade, patients were randomly allocated to have either cricoid pressure (Group C) or sham pressure (Group S). The view of the glottis through the laryngeal mask was assessed before and after the test pressure, and tracheal intubation through the mask was attempted using a fibreoptic bronchoscope. The test pressure did not alter the view of the glottis in any patient in group S, whereas it narrowed the glottic aperture in 16 out of 35 patients in group C. The fibrescope was inserted into the trachea in all patients in group S and in 25 patients in group C. The success rate of tracheal intubation in group S (31 patients) was significantly higher than in group C (21 patients, P << 0.001; 95% CI for difference: 9-48%). The time for insertion of the fibrescope in group S (median (95% CI): 12 (11-12) s) was significantly faster than in group C (16 (14-17) s, P << 0.001; 95% CI for difference: 3-6 s), and the time for tracheal intubation in group S (16 (15-18) s) was significantly faster than in group C (22 (19-24) s, P < 0.0005; 95% CI for difference: 3-7 s). Cricoid pressure after insertion of the laryngeal mask makes tracheal intubation through the mask significantly more difficult.  (+info)

The cricoid cartilage is a ring-like piece of cartilage that forms the lower part of the larynx, or voice box. It is located in the front portion of the neck, and lies just below the thyroid cartilage, which is the largest cartilage in the larynx and forms the Adam's apple.

The cricoid cartilage serves as a attachment site for several important structures in the neck, including the vocal cords and the trachea (windpipe). It plays an important role in protecting the airway during swallowing by providing a stable platform against which the food pipe (esophagus) can open and close.

In medical procedures such as rapid sequence intubation, the cricoid cartilage may be pressed downward to compress the esophagus and help prevent stomach contents from entering the airway during intubation. This maneuver is known as the "cricoid pressure" or "Sellick's maneuver."

Thyroid cartilage is the largest and most superior of the laryngeal cartilages, forming the front and greater part of the larynx, also known as the "Adam's apple" in humans. It serves to protect the vocal cords and provides attachment for various muscles involved in voice production. The thyroid cartilage consists of two laminae that join in front at an angle, creating a noticeable prominence in the anterior neck. This structure is crucial in speech formation and swallowing functions.

Laryngeal cartilages refer to the various pieces of cartilage that make up the structure of the larynx, also known as the voice box. The larynx is a crucial part of the respiratory system, located in the neck between the pharynx and the trachea. It plays a vital role in protecting the lower airways from food or drink entering the windpipe, as well as producing sound during speech.

There are several laryngeal cartilages, including:

1. Thyroid cartilage: This is the largest and most superior of the laryngeal cartilages. It forms the Adam's apple in men and has a prominent notch in the front called the thyroid notch. The thyroid cartilage protects the larynx and provides attachment for various muscles and ligaments.
2. Cricoid cartilage: This is the only complete ring of cartilage in the airway and lies inferior to the thyroid cartilage. It has a broad, flat superior portion called the cricoid lamina and a narrower, more curved inferior portion called the cricoid arch. The cricoid cartilage serves as an attachment site for several muscles and ligaments involved in breathing and swallowing.
3. Arytenoid cartilages: These are paired, pyramid-shaped structures that sit on top of the cricoid cartilage. They help form the posterior portion of the laryngeal inlet and provide attachment for the vocal cords (vocal folds). The arytenoid cartilages play a crucial role in voice production and respiration.
4. Corniculate cartilages: These are small, conical-shaped structures that project from the superior aspect of each arytenoid cartilage. They help form the most posterior portion of the laryngeal inlet.
5. Cuneiform cartilages: These are tiny, flat, crescent-shaped structures located near the corniculate cartilages. They also contribute to forming the posterior aspect of the laryngeal inlet.

These laryngeal cartilages work together to protect the airway, facilitate breathing, and enable voice production.

The larynx, also known as the voice box, is a complex structure in the neck that plays a crucial role in protection of the lower respiratory tract and in phonation. It is composed of cartilaginous, muscular, and soft tissue structures. The primary functions of the larynx include:

1. Airway protection: During swallowing, the larynx moves upward and forward to close the opening of the trachea (the glottis) and prevent food or liquids from entering the lungs. This action is known as the swallowing reflex.
2. Phonation: The vocal cords within the larynx vibrate when air passes through them, producing sound that forms the basis of human speech and voice production.
3. Respiration: The larynx serves as a conduit for airflow between the upper and lower respiratory tracts during breathing.

The larynx is located at the level of the C3-C6 vertebrae in the neck, just above the trachea. It consists of several important structures:

1. Cartilages: The laryngeal cartilages include the thyroid, cricoid, and arytenoid cartilages, as well as the corniculate and cuneiform cartilages. These form a framework for the larynx and provide attachment points for various muscles.
2. Vocal cords: The vocal cords are thin bands of mucous membrane that stretch across the glottis (the opening between the arytenoid cartilages). They vibrate when air passes through them, producing sound.
3. Muscles: There are several intrinsic and extrinsic muscles associated with the larynx. The intrinsic muscles control the tension and position of the vocal cords, while the extrinsic muscles adjust the position and movement of the larynx within the neck.
4. Nerves: The larynx is innervated by both sensory and motor nerves. The recurrent laryngeal nerve provides motor innervation to all intrinsic laryngeal muscles, except for one muscle called the cricothyroid, which is innervated by the external branch of the superior laryngeal nerve. Sensory innervation is provided by the internal branch of the superior laryngeal nerve and the recurrent laryngeal nerve.

The larynx plays a crucial role in several essential functions, including breathing, speaking, and protecting the airway during swallowing. Dysfunction or damage to the larynx can result in various symptoms, such as hoarseness, difficulty swallowing, shortness of breath, or stridor (a high-pitched sound heard during inspiration).

Cartilage is a type of connective tissue that is found throughout the body in various forms. It is made up of specialized cells called chondrocytes, which are embedded in a firm, flexible matrix composed of collagen fibers and proteoglycans. This unique structure gives cartilage its characteristic properties of being both strong and flexible.

There are three main types of cartilage in the human body: hyaline cartilage, elastic cartilage, and fibrocartilage.

1. Hyaline cartilage is the most common type and is found in areas such as the articular surfaces of bones (where they meet to form joints), the nose, trachea, and larynx. It has a smooth, glassy appearance and provides a smooth, lubricated surface for joint movement.
2. Elastic cartilage contains more elastin fibers than hyaline cartilage, which gives it greater flexibility and resilience. It is found in structures such as the external ear and parts of the larynx and epiglottis.
3. Fibrocartilage has a higher proportion of collagen fibers and fewer chondrocytes than hyaline or elastic cartilage. It is found in areas that require high tensile strength, such as the intervertebral discs, menisci (found in joints like the knee), and the pubic symphysis.

Cartilage plays a crucial role in supporting and protecting various structures within the body, allowing for smooth movement and providing a cushion between bones to absorb shock and prevent wear and tear. However, cartilage has limited capacity for self-repair and regeneration, making damage or degeneration of cartilage tissue a significant concern in conditions such as osteoarthritis.

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. It provides a cushion between bones and allows for smooth movement by reducing friction. Articular cartilage also absorbs shock and distributes loads evenly across the joint, protecting the bones from damage. It is avascular, meaning it does not have its own blood supply, and relies on the surrounding synovial fluid for nutrients. Over time, articular cartilage can wear down or become damaged due to injury or disease, leading to conditions such as osteoarthritis.

Aspiration pneumonia is a type of pneumonia that occurs when foreign materials such as food, liquid, or vomit enter the lungs, resulting in inflammation or infection. It typically happens when a person inhales these materials involuntarily due to impaired swallowing mechanisms, which can be caused by various conditions such as stroke, dementia, Parkinson's disease, or general anesthesia. The inhalation of foreign materials can cause bacterial growth in the lungs, leading to symptoms like cough, chest pain, fever, and difficulty breathing. Aspiration pneumonia can be a serious medical condition, particularly in older adults or individuals with weakened immune systems, and may require hospitalization and antibiotic treatment.

Intubation, intratracheal is a medical procedure in which a flexible plastic or rubber tube called an endotracheal tube (ETT) is inserted through the mouth or nose, passing through the vocal cords and into the trachea (windpipe). This procedure is performed to establish and maintain a patent airway, allowing for the delivery of oxygen and the removal of carbon dioxide during mechanical ventilation in various clinical scenarios, such as:

1. Respiratory failure or arrest
2. Procedural sedation
3. Surgery under general anesthesia
4. Neuromuscular disorders
5. Ingestion of toxic substances
6. Head and neck trauma
7. Critical illness or injury affecting the airway

The process of intubation is typically performed by trained medical professionals, such as anesthesiologists, emergency medicine physicians, or critical care specialists, using direct laryngoscopy or video laryngoscopy to visualize the vocal cords and guide the ETT into the correct position. Once placed, the ETT is secured to prevent dislodgement, and the patient's respiratory status is continuously monitored to ensure proper ventilation and oxygenation.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
