Dogliotti's Principle
Dogliotti's principle is a principle in epidural anaesthesia first described by Professor Achille Mario Dogliotti in 1933. It is a method for the identification of the epidural space, a potential space. As a needle is advanced through the ligamentum flavum, to the epidural space, with constant pressure applied to the piston of a syringe, loss of resistance occurs once the needle enters the epidural space due to the change in pressure. The identification of this space, allows subsequent administration of epidural anaesthesia, a technique used primarily for analgesia during childbirth. This technique remains in use at , and is commonly referred to the loss of resistance to saline technique (LORS) or its variation, the loss of resistance to air technique (LORA). These use, respectively, saline or air to identify the epidural space. The LORS technique is generally favoured due to the increased complication risk with the LORA technique such as pneumocephalus or air embolism. See a ...

Epidural Space
In anatomy, the epidural space is the potential space between the dura mater and vertebrae ( spine). The anatomy term "epidural space" has its origin in the Ancient Greek language; , "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space". In humans the epidural space contains lymphatics, spinal nerve roots, loose connective tissue, adipose tissue, small arteries, dural venous sinuses and a network of internal vertebral venous plexuses. Cranial epidural space In the skull, the periosteal layer of the dura mater adheres to the inner surface of the skull bones while the meningeal layer lays over the arachnoid mater. Between them is the epidural space. The two layers of the dura mater separate at several places, with the meningeal layer projecting deeper into the brain parenchyma forming fibrous septa that compartmentalize the brain tissue. At these sites, the epidural space is wide enough to house the epidural venous sinuses. There ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potential Space
In anatomy, a potential space is a space between two adjacent structures that are normally pressed together (directly apposed). Many anatomic spaces are potential spaces, which means that they are potential rather than realized (with their realization being dynamic according to physiologic or pathophysiologic events). In other words, they are like an empty plastic bag that has not been opened (two walls collapsed against each other; no interior volume until opened) or a balloon that has not been inflated. The pleural cavity, pleural space, between the visceral and parietal pleura of the lung, is a potential space. Though it only contains a small amount of fluid normally, it can sometimes accumulate fluid or air that widens the space. The pericardial space is another potential space that may fill with fluid (effusion) in certain disease states (e.g. pericarditis; a large pericardial effusion may result in cardiac tamponade.

Ligamentum Flavum
The ligamenta flava (singular, ''ligamentum flavum'', Latin for ''yellow ligament'') are a series of ligaments that connect the ventral parts of the laminae of adjacent vertebrae. They help to preserve upright posture, preventing hyperflexion, and ensuring that the vertebral column straightens after flexion. Hypertrophy can cause spinal stenosis. Structure Each ligamentum flavum connects the laminae two adjacent vertebrae. They begin with the junction of the axis and third cervical vertebra, continuing down to the junction of the fifth lumbar vertebra and the sacrum. They are best seen from the interior of the vertebral canal. when looked at from the outer surface they appear short, being overlapped by the lamina of the vertebral arch. Each ligament consists of two lateral portions which commence one on either side of the roots of the articular processes, and extend backward to the point where the laminae meet to form the spinous process; the posterior margins of ...

British Journal Of Anaesthesia
The ''British Journal of Anaesthesia'' is a monthly peer-reviewed medical journal published by Elsevier on behalf of the Royal College of Anaesthetists (and its Faculty of Pain Medicine), the College of Anaesthesiologists of Ireland, and the Hong Kong College of Anaesthesiologists, for all of which it serves as their official journal. The journal covers all aspects of anaesthesia, perioperative medicine, intensive care medicine, and pain management. The editor-in-chief is Hugh C. Hemmings (Weill Cornell Medical College). The journal was established in 1923, one year after the first anaesthetic journal ('' Anesthesia & Analgesia'') was published by the International Anaesthesia Research Society. The first editor-in-chief was H.M. Cohen, who edited the journal from 1923 to 1928. Recent editors-in-chief include Ravi Mahajan (University of Nottingham), Charles Reilly (University of Sheffield), and Jennifer Hunter (University of Liverpool).

Analgesia
Pain management is an aspect of medicine and health care involving relief of pain (pain relief, analgesia, pain control) in various dimensions, from acute and simple to chronic and challenging. Most physicians and other health professionals provide some pain control in the normal course of their practice, and for the more complex instances of pain, they also call on additional help from a specific medical specialty devoted to pain, which is called pain medicine. Pain management often uses a multidisciplinary approach for easing the suffering and improving the quality of life of anyone experiencing pain, whether acute pain or chronic pain. Relief of pain in general (analgesia) is often an acute affair, whereas managing chronic pain requires additional dimensions. The typical pain management team includes medical practitioners, pharmacists, clinical psychologists, physiotherapists, occupational therapists, recreational therapists, physician assistants, nurses, and de ...

Childbirth
Childbirth, also known as labour and delivery, is the ending of pregnancy where one or more babies exits the internal environment of the mother via vaginal delivery or caesarean section. In 2019, there were about 140.11 million births globally. In the developed countries, most deliveries occur in hospitals, while in the developing countries most are home births. The most common childbirth method worldwide is vaginal delivery. It involves four stages of labour: the shortening and opening of the cervix during the first stage, descent and birth of the baby during the second, the delivery of the placenta during the third, and the recovery of the mother and infant during the fourth stage, which is referred to as the postpartum. The first stage is characterized by abdominal cramping or back pain that typically lasts half a minute and occurs every 10 to 30 minutes. Contractions gradually becomes stronger and closer together. Since the pain of childbirth correlates with c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumocephalus
Pneumocephalus is the presence of air or gas within the cranial cavity. It is usually associated with disruption of the skull: after head and facial trauma, tumors of the skull base, after neurosurgery or otorhinolaryngology, and rarely, spontaneously. Pneumocephalus can occur in scuba diving, but is very rare in this context. If there is a valve mechanism which allows air to enter the skull but prevents it from escaping, a tension pneumocephalus can occur (similar to what can happen in a tension pneumothorax). CT scans of patients with a tension pneumocephalus typically show air that compresses the frontal lobes of the brain, which results in a tented appearance of the brain in the skull known as the Mount Fuji sign. The name is derived from the resemblance of the brain to Mount Fuji in Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Embolism
An air embolism, also known as a gas embolism, is a blood vessel blockage caused by one or more bubbles of air or other gas in the circulatory system. Air can be introduced into the circulation during surgical procedures, lung over-expansion injury, decompression, and a few other causes. Air embolisms may also occur in the xylem of vascular plants, especially when suffering from water stress. Divers can develop ''arterial'' gas embolisms as a consequence of lung over-expansion injuries. Breathing gas introduced into the venous system of the lungs due to pulmonary barotrauma will not be trapped in the alveolar capillaries, and will consequently be circulated to the rest of the body through the systemic arteries, with a high risk of embolism. Inert gas bubbles arising from decompression are generally formed in the ''venous'' side of the systemic circulation, where inert gas concentrations are highest, these bubbles are generally trapped in the capillaries of the lungs where ...

Epidural
Epidural administration (from Ancient Greek ἐπί, , upon" + ''dura mater'') is a method of medication administration in which a medicine is injected into the epidural space around the spinal cord. The epidural route is used by physicians and nurse anesthetists to administer local anesthetic agents, analgesics, diagnostic medicines such as radiocontrast agents, and other medicines such as glucocorticoids. Epidural administration involves the placement of a catheter into the epidural space, which may remain in place for the duration of the treatment. The technique of intentional epidural administration of medication was first described in 1921 by Spanish military surgeon Fidel Pagés. In the United States, over 50% of childbirths involve the use of epidural anesthesia. Epidural anaesthesia causes a loss of sensation, including pain, by blocking the transmission of signals through nerve fibres in or near the spinal cord. For this reason, epidurals are commonly used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Neuraxial Anesthesia
The history of neuraxial anesthesia goes back to 1885. 19th century In 1855, Friedrich Gaedcke (18281890) became the first to chemically isolate cocaine, the most potent alkaloid of the coca plant. Gaedcke named the compound "erythroxyline". In 1884, Austrian ophthalmologist Karl Koller (18571944) instilled a 2% solution of cocaine into his own eye and tested its effectiveness as a local anesthetic by pricking the eye with needles. His findings were presented a few weeks later at annual conference of the Heidelberg Ophthalmological Society. The following year, William Halsted (18521922) performed the first brachial plexus block. Also in 1885, James Leonard Corning (18551923) injected cocaine between the spinous processes of the lower lumbar vertebrae, first in a dog and then in a healthy man. His experiments are the first published descriptions of the principle of neuraxial blockade. On August 16, 1898, German surgeon August Bier (18611949) performed surgery under s ...
