Budding musicians learning to play wind instruments need to be careful, doctors have said, after a Greater Taichung man learning to play the saxophone suffered a stroke as a result of blowing too forcefully into the mouthpiece.
Lin Mao-yuan (林茂淵), 63, said he and a few friends had signed up for saxophone lessons.
“Our teacher told us that as beginners, we should take a break after 15 minutes of practice. I have always followed this rule,” Lin said, adding that he exercises regularly to alleviate his high blood pressure.
He was practicing at home in November last year and, as his practice session was going well, he continued playing for 20 minutes.
“Suddenly, I felt dizzy, and my was head spinning. My lips, left hand and left leg became numb. I stopped blowing, but the condition persisted. Then I realized I was suffering a stroke, so I yelled for my wife to call an ambulance, which took me to the hospital within 15 minutes,” he said.
At the hospital, his systolic blood pressure was measured at 210mmHg, and he had a blood clot measuring about 1cm in his brain stem.
“The brain stem is difficult to operate on without damaging the cerebral tissues. So it was better to use supportive therapy to treat this case, with medications to control blood pressure and brain hypertension,” China Medical University neurologist Chen Chun-chung (陳春忠) said.
“Lin was very lucky. Most people who suffer a stroke near the brain stem are unconscious or paralyzed when they arrive at the hospital. If he kept on playing the saxophone and hadn’t sought treatment right away, 5 milliliters more blood could have left him partially paralyzed,” Chen said.
“Bleeding in the brain stem commonly occurs during brain strokes. In about 90 percent of these cases, the patient dies or lapses into a coma,” he added. “When people exert themselves to blow on a musical instrument, their blood pressure is heightened, and this can cause blood vessels in the brain to burst.”
Lin was discharged from hospital the following day, after tests indicated he did not have further internal bleeding.
He was back to work within one month.
However, Lin said that the experience had killed his desire to learn to play the saxophone and that he had since sold the instrument.
“In the past, I measured my blood pressure when I felt some discomfort. Now I measure it every day,” he said. “I used to hold my alcohol quite well, and could drink up to 700ml of whiskey at one sitting. Now I am trying to give up both alcohol and smoking.”
Chen said that 20 percent of strokes are caused by hypertension, of which 85 percent of cases are due to not keeping blood pressure under control.
“We recommend that people with high blood pressure not take up wind instruments, such as the saxophone or trumpet, which require strong lung capacity. They should take medication to control blood pressure. Going on and off medication, which causes blood pressure to go up or down, is also dangerous,” Chen said.
He added that people with high blood pressure should not attempt strenuous exercise.
“Fast walking is a good activity. It can improve blood vessel elasticity. With regular exercise, 20 percent of the patients are able to keep their condition under control without medication,” he said.
Former Czech Republic-based Taiwanese researcher Cheng Yu-chin (鄭宇欽) has been sentenced to seven years in prison on espionage-related charges, China’s Ministry of State Security announced yesterday. China said Cheng was a spy for Taiwan who “masqueraded as a professor” and that he was previously an assistant to former Cabinet secretary-general Cho Jung-tai (卓榮泰). President-elect William Lai (賴清德) on Wednesday last week announced Cho would be his premier when Lai is inaugurated next month. Today is China’s “National Security Education Day.” The Chinese ministry yesterday released a video online showing arrests over the past 10 years of people alleged to be
THE HAWAII FACTOR: While a 1965 opinion said an attack on Hawaii would not trigger Article 5, the text of the treaty suggests the state is covered, the report says NATO could be drawn into a conflict in the Taiwan Strait if Chinese forces attacked the US mainland or Hawaii, a NATO Defense College report published on Monday says. The report, written by James Lee, an assistant research fellow at Academia Sinica’s Institute of European and American Studies, states that under certain conditions a Taiwan contingency could trigger Article 5 of NATO, under which an attack against any member of the alliance is considered an attack against all members, necessitating a response. Article 6 of the North Atlantic Treaty specifies that an armed attack in the territory of any member in Europe,
LIKE FAMILY: People now treat dogs and cats as family members. They receive the same medical treatments and tests as humans do, a veterinary association official said The number of pet dogs and cats in Taiwan has officially outnumbered the number of human newborns last year, data from the Ministry of Agriculture’s pet registration information system showed. As of last year, Taiwan had 94,544 registered pet dogs and 137,652 pet cats, the data showed. By contrast, 135,571 babies were born last year. Demand for medical care for pet animals has also risen. As of Feb. 29, there were 5,773 veterinarians in Taiwan, 3,993 of whom were for pet animals, statistics from the Animal and Plant Health Inspection Agency showed. In 2022, the nation had 3,077 pediatricians. As of last
XINJIANG: Officials are conducting a report into amending an existing law or to enact a special law to prohibit goods using forced labor Taiwan is mulling an amendment prohibiting the importation of goods using forced labor, similar to the Uyghur Forced Labor Prevention Act (UFLPA) passed by the US Congress in 2021 that imposed limits on goods produced using forced labor in China’s Xinjiang region. A government official who wished to remain anonymous said yesterday that as the US customs law explicitly prohibits the importation of goods made using forced labor, in 2021 it passed the specialized UFLPA to limit the importation of cotton and other goods from China’s Xinjiang Uyghur region. Taiwan does not have the legal basis to prohibit the importation of goods
