The technique of the stellate ganglion block is widely used as it is relatively simple and safe. But it can cause severe complications because there are major blood vessels and nerves around the stellate ganglion. We practiced CPR because of the respiratory failure caused by severe hematoma in the neck following the stellate ganglion block. A 46-year-old male patient admitted to ENT department because of the both sudden sensorineural hearing loss that happened after URI. He was referred to Pain Clinic for further evaluation and treatment. We decided to block the stellate ganglion. We injected 6ml of 0.5% mepivacaine on both sides of the stellate ganglion. There were no blood aspiration and abnormal vital signs during the 30 minute observation, either. Three hours after he went to the private room, he had pain and edema in his neck, but no respiratory defficulty. But later, respiratory failure was suddenly followed. So we practiced CPR. We confirmed severe hematomas in the neck through CT scanning. Hematomas is removed and the ruptured blood vessels which is supposed to be muscular branch of vertebral artery is ligated under general anesthesia. The patient was discharged from hospital after the treatment of pneumonia and duodenal ulcer as complications. We recommand you to compress the block site more than five minutes and not to prick with the needle several times at one point to prevent the formation of hematomas.

A pulse is generated when the heart pumps blood into the arterial system. The heart pumps blood only when it contracts, not when it relaxes; therefore, blood enters the arterial system in a cyclical form. Artery beating is visible in some parts of the body surface, such as the radial artery of the wrist. This paper mainly uses the feature in which near-infrared spectroscopy penetrates skin to construct a non-invasive measurement system that can measure small vibration in the subcutaneous tissue of the human body, and then uses it for the pulse measurement. This measurement system uses the optical moir$\acute{e}$ principle, together with the fringe displacement made by small vibration in the subcutaneous tissue, and an image analysis program to calculate the height variation from small vibrations in the subcutaneous tissue. It completes a measurement system that records height variation with time, and that together with a fast Fourier transform (FFT) program, they can convert the pulse waveform generated by vibration (time-amplitude) to heartbeat frequency (frequency-amplitude). This is a new and non-invasive medical assistance system for measuring the pulse of the human body, with the advantages of being simple, fast, safe and objective.

Pulse waves continuously change with respect to the characteristics and status of the cardiovascular system and in relation to the blood pressure (BP) and the pulse wave velocity (PWV). Monitoring the vascular condition by analyzing the variations in pulse waveforms has been used to diagnose vascular disorders and in drug treatment of arteriosclerosis and peripheral circulatory obstruction. In this paper, we investigated the vascular characteristic index with regard to the BP and classified by pulse wave signals. The pressure pulse wave and photoplethysmography (PPG) were measured simultaneously while subjects exercised, producing changes in the BP, to analyze the variation in the vascular characteristic index. We investigated the correlation between the BP and vascular characteristic index with regard to the classification methods of the pulse wave. The reflection index (RI) and vascular stiffness index were correlated with the diastolic BP, but no correlation was found between these parameters and the systolic BP. These results suggest the possibility of estimating BP through simple measurements of pulse waves.

The From COVID-19 until recently, the demand for hiking has been rapidly increasing due to the popularization of mountain seekers.,On weekends and holidays, people who do not hike frequently while hiking in large and small mountains to see wildflowers and foliage in the mountains are more likely to be exposed to safety accidents due to an increase in sudden muscle use.,If you fall or get muscle damage during a hike, you can prevent a major accident with a simple treatment. In some cases, the error of first aid may permanently damage the important function of the body.,In particular, during a safety accident on a mountain, while climbing in light clothes, the body temperature rises due to the sweat that was shed at the beginning, and the blood pressure rises due to the contraction of the blood vessels due to the drop in body temperature from the top, resulting in an emergency such as cardiac arrest.,According to statistics from the National Park Service, nearly half (48%) of deaths in national parks are known to be sudden cardiac deaths.,There are many safety accidents that occur frequently in the mountains, but among them, we will study how to cope with acute diseases such as cardiac arrest due to increased blood pressure due to insufficient body temperature control, chest pain or dyspnea, and heart burden due to excessive hiking.

Oxidative stress caused by elevated reactive oxygen species (ROS) in the heart causes various heart diseases. Oxidative stress is known as a factor that causes diseases in various organs as well as the heart. Diseases such as heart failure, myocardial infarction, and cardiomyopathy caused by oxidative stress in the heart can be treated with medication or surgery. Recently, blood cells concentrate (BCC) is used in various treatment areas such as orthopedics, gynecology, and urology. BCC therapy is applied to treatment by concentrating platelets and white blood cells necessary for regeneration through simple centrifugation using autologous blood. As the platelets are activated, many growth factors are released from alpha granules of the platelets. Growth factors such as TGF-β1, PDGF, VEGF, and EGF derived from platelets are involved in various cell signaling pathway. Due to these growth factors, BCC can contribute to tissue regeneration and can treat various diseases. CD34+ cells contained in BCC may also play an important role in tissue regeneration. In this study, we investigated whether BCC has a regenerative effect on heart disease, and if so, what mechanism causes the effect. To observe this, cardiomyocyte cells were treated with H₂O₂ to induce oxidative stress. And the effect was confirmed in the presence or absence of BCC. As a result, in the presence of BCC, the oxidative stress of cardiomyocyte cells was reduced and cell damage was also reduced. These results suggest that BCC therapy can be a new treatment alternative for heart disease.
