无创动态血压监测(ABPM)技术的推广应用,为临床研究开拓了新的领域.我们对歼击机飞行学员和教员各20例在同一飞行过程中的血压变化情况进行动态监测,并从航空医学角度加以讨论.1.对象与方法:以20例歼击机飞行学员为观察组,年龄22～25岁(23±1.5岁),飞行总时数110～130小时(120±8.5小时),另设20例歼击机飞行教员为对照组,年龄28～35岁(29±4.8岁),飞行总时数700～1200小时(950±180小时),两组均无高血压史,平时查体偶测血压值均低于18.7/12.0kPa(140/90mmHg),监测前48小时无饮酒和服药史,两组于同一机场同一飞行科目时进行ABPM,飞行高度0～8000米,ABPM采用无创携带式血压监测仪,每间隔2分钟测压一次,监测时间60分钟,包括(1)飞行前(10分钟);(2)飞行准备阶段(6分钟);(3)起飞阶段(6分钟);(4)空域飞行(22分钟);(5)着陆阶段(6分钟);(6)飞行后(10分钟),其间共测30次,如有效测量读数<23次则退出本实验,40例均进入统计,血压变化用自身配对t检验.
The popularization and application of noninvasive ambulatory blood pressure monitoring (ABPM) has opened up a new field for clinical research.We dynamically monitored the changes of blood pressure during the same flight in each of the 20 fighter pilots and trainers, and from the perspective of aeromedicine Discussed.1.Objects and Methods: A total of 20 fighter pilots were selected as the observation group, aged 22-25 years (23 ± 1.5 years) and 110-130 hours (120 ± 8.5 hours) The flight instructor was a control group aged 28-35 years (29 ± 4.8 years) with a total flight time of 700-1200 hours (950 ± 180 hours). There was no history of hypertension in both groups. At 18.7 / 12.0kPa (140 / 90mmHg), there was no alcohol consumption and medication history within 48 hours before the monitoring. The two groups conducted ABPM at the same flight plane at the same airport between 0 and 8,000 meters. ABPM used a noninvasive portable blood pressure monitor. (2) flight preparation phase (6 minutes); (3) takeoff phase (6 minutes); (4) airspace flight (6 minutes); 22 minutes); (5) landing phase (6 minutes); (6) after the flight (10 minutes), during which a total of 30 times, if the effective measurement of reading <23 times In this experiment, 40 were involved in the statistics, change in blood pressure with their paired t test.
