Advantages Of Video Laryngoscope
1. Advantages of video laryngoscope There is no doubt that videolaryngoscopy has been one of the major advances in anesthesia practice in recent years. The main challenge is to determine to what extent videolaryngoscopy should be used in routine clinical practice and which videolaryngoscope will perform best. Going from a standard Macintosh laryngoscope to a video laryngoscope is like going from a standard mobile phone to a smartphone. There have been calls for videolaryngoscopy as a first-line tool for airway management. Most importantly, in the 2015 guidelines of the British Difficult Airway Association, the role of videolaryngoscopy in the management of difficult tracheal intubation has been recognized. The guideline recommends that all anesthesiologists should be trained in the use of videolaryngoscopes and have immediate access to videolaryngoscopes at any time. Furthermore, videolaryngoscopy has been recommended for endotracheal intubation in obese patients, who are known to be at higher risk of airway management-related complications. Beyond the field of anesthesia, it has been predicted that videolaryngoscopy will dominate the field of emergency airway management in the future. Price appears to be the main factor holding back the tide for now. The main reasons that make people enthusiastic about video laryngoscopy are as...

What Is The Important Role Of Oximetry in COVID-19?
With the increasing emphasis on health, the demand for oximeters is gradually increasing, especially after the COVID-19, the demand for oximeters is exponentially more widespread! So what is so unique about this little oximeter and what important role does it play in the fight against the new epidemic in this smokeless battlefield? What is an oximeter? An oximeter, also known as a pulse oximeter, is a device that monitors the oxygen content of blood in the body in real time without the need for blood sampling, through a detector or sensor. It is a small medical device that measures the body’s oxygen saturation, pulse rate and perfusion index. The oxygen saturation of a normal person is between 94% and 100%, below 90% needs to be taken seriously. COVID-19 can lead to lung infections which can lower blood oxygen levels. When blood oxygen levels are at a low level, one may feel fatigue and shortness of breath, even without any discomfort, but such a situation can be dangerous. Oximetry is one of the clinical diagnostic methods for neocoronary pneumonia. Changes in blood oxygen levels can be used to determine if you have neocoronary pneumonia, and for some mild cases of neocoronary...

Summary of basic knowledge of ultrasound(part two)
Section 3 Ultrasound examination of the pancreas and its normal values At present, there is no uniform standard for the ultrasound measurement of normal pancreas, and most authors use the thickness (anterior-posterior diameter) of the pancreas as the standard. specific method: one. Pancreatic head measurement 1. Select a facet. Long-axis section of the pancreas, showing the head of the pancreas clearly; 2. Measurement site: measured in front of the inferior vena cava, measurement generally does not include the uncinate process 3. Normal reference value (adult): ≤2.5cm two. Pancreatic body measurement ! ． Select the slice: long-axis slice of the pancreas to show the body of the pancreas clearly: 2. Measurement site: Measure in the vertical line in front of the abdominal aorta. 3. Normal reference value (adult): ≤2.0cm three. Measurement of pancreatic tail 1. Select the section: long-axis section of the pancreas to clearly show the tail of the pancreas: 2 Measurement site: measure at the left edge of the abdominal aorta or the left edge of the spine; 3. Normal reference value (adult): ≤2.0cm Section IV Renal ultrasonography measurement methods and normal values one. Kidney length (upper and lower diameter) measurement 1. Measurement plane: Coronal or sagittal longest plane...

What Is Doppler Ultrasound?
Doppler ultrasound is a non-invasive test that uses high-frequency sound waves (ultrasound) reflected from circulating red blood cells to assess blood flow in blood vessels. Conventional ultrasound uses sound waves to create images but cannot show blood flow. Doppler ultrasound can help diagnose many diseases, including: Thrombus Poorly functioning valves in the veins of the legs, which may cause blood or other fluids to build up in the legs (venous insufficiency) Heart valve defects and congenital heart disease Arterial blockage (arterial occlusion) Reduced blood circulation in the legs (peripheral arterial disease) Arterial bulge (aneurysm) Narrowing of arteries, such as in the neck (carotid stenosis) Doppler ultrasound can assess the speed of blood flow by measuring the rate of change in pitch (frequency). During a Doppler ultrasound examination, a technician (sonographer) trained in ultrasound imaging presses a small, soap-sized hand-held device (transducer) against the skin of the area being examined and removes it from an area as needed Move to another area. This test is an alternative to more invasive tests such as angiography, which involves injecting a contrast agent into the blood vessels so that they can be seen clearly on X-ray images. Doppler ultrasonography can also help doctors check...

Clinical Significance of Platelet Count
Plateletcount is one of the important indicators for the screening of human hemostasis and coagulation dysfunction. The increase or decrease ofplatelet count is closely related to various bleeding and thromboticdiseases in addition to the individual’s own physiologica fluctuations. 1. Physiological changes The platelet count of normal people fluctuates with time and physiological state. Usually higher in the afternoon than in the morning, higher in winter than in spring, higher in plateau residents than in plains, higher after menstruation than before menstruation increases in the middle and late stages of pregnancy decreases afterdelivery, increases after exercise and a full meal, and recovers after rest. Plateletcount is slightly low in newborns, but increases significantly after two weeks, and can reach adult levels within half a year 2.Pathologicalincrease Thrombocytosis is defined as a platelet count exceeding 350×109/L which is common in: ① Primary hyperplasia: Myeloproliferative syndrome, essential thrombocythemia, chronic myelogenous leukemia, polycythemia vera, idiopathic myelofibrosis, etc. 2 Reactive hyperplasia: Acute and chronic inflammation, acute massive blood loss, acute hemolysis tumor, recent surgen (especially after splenectomy), iron-deficiency anemia, early stage of malignanttumor, etc., platelets may have reactive hyperplasia, milo increase or transient increase. Other diseases: Heart disease, liver cirrhosis, chronic pancreatitis, burns,renal failure,...
