Immediate cardiopulmonary resuscitation (CPR) could double the chance of survival for children who experience out-of-hospital cardiac arrest, a study released on Thursday last week showed.
The study by Linkou Chang Gung Memorial Hospital also showed that CPR for children having cardiac arrests could prevent brain damage caused by a lack of oxygen.
A team at the hospital studied 152 patients younger than 18 from 2005 to 2016 who experienced out-of-hospital cardiac arrests and were later admitted to the hospital, pediatric general medicine director Lee Jung (李嶸) told a news conference.
The study showed that 15 patients received CPR prior to being admitted to the hospital, and of that group, there was a 60 percent chance to restart the heart at the hospital, he said.
For the other cases in which patients received no CPR prior to being admitted, there was a 32 percent chance of restarting the heart, he added.
Many parents rush their child to the hospital without first trying CPR, because they do not understand its importance or they lack the confidence to perform it, but the immediate use of CPR doubles the chance of survival, Lee said.
The study included an equal number of male and female patients, and 47 percent were younger than one.
Out-of-hospital cardiac arrests in children occur on average 1.5 times every month, among which 54 percent are due to choking and up to 76 percent occur at home, it showed.
The study found that only one-third of the patients regain heartbeats after reaching the hospital, 14 percent survive and 5 percent function normally afterward.
Complications resulting from a lack of oxygen to the brain could increase the risks of hindered brain development and even cerebral palsy, hospital attending physician Wu Chang-teng (吳昌騰) said.
Permanent damage could occur if the brain is deprived of oxygen for more than six minutes, and CPR using external force to supply the brain with more blood and oxygen could prevent the situation from happening, he said.
Key points to focus on when performing CPR include quick and hard compressions, the rebound of the chest and continuity of the compressions, Wu said.
Compressions should be administered at a rate of at least 100 per minute, and at a depth of about one-third of the chest capacity each time, he said, adding that the rising of the chest signals the timing for the next compression, and the break period between compressions should not exceed 10 seconds.
Deliver two breaths to the patient’s mouth after each set of 30 compressions, and if the heart does not restart, repeat the cycle until it is beating or an ambulance arrives, he said.
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country. All of Taiwan except for Hualien and Taitung counties is to be under an “orange” air quality alert tomorrow, indicating air quality that is unhealthy for sensitive groups. In China, areas from Shandong to Shanghai have been enveloped in haze since Saturday, the ministry said in a news release. Yesterday, hourly concentrations of PM2.5 in these areas ranged from 65 to 160 micrograms per cubic meter (mg/m³), and pollutants were
Taiwan’s armed forces have established response protocols for a wide range of sudden contingencies, including the “Wan Chun Plan” to protect the head of state, the Ministry of Defense (MND) said today. After US President Donald Trump on Saturday launched a series of airstrikes in Venezuela and kidnapped Venezuelan President Nicolas Maduro, concerns have been raised as to whether China would launch a similar “decapitation strike” on Taiwan. The armed forces regularly coordinate with relevant agencies and practice drills to ensure preparedness for a wide range of scenarios, Vice Minister of National Defense Hsu Szu-chien (徐斯儉) told reporters before a
