6) Key words: 821.52, R442.8 Document code: B Article ID :2001-5428 (2001) 06-0450-011991 ~ 20O0 during a l2 cases of our hospital because of long-distance cross-country training lead severe hyperventilation syndrome, and incidence of l5 times. To this end, we conducted the analysis, the report is as follows. The clinical data of patients l2 1 of Guangxi Liuzhou area in which military officers and men of 8 males and 4 females, age 18-2l years old, are then recruited new fighters. L1 Southern soldiers were nationals, the North nationality 1; town 9 recruits, recruits three people in rural areas. Onset were in the morning or evening, with an average temperature of 32 ℃ below the 5km (women 3km) off-road training 2 / 3 of the above or within lOmin after the onset. Clinical manifestations of dyspnea, mouth breathing l5 times, weakness or flaccid paralysis of the l5 passengers, 13 passengers and limb numbness, convulsions or tonic spasm of limbs, 12 people, 3 people showed a transient disturbance of consciousness; 1 v. Training When sweating more, sweat more than others, no significant distribution of onset of hunger: January 2 people, February 3 passengers, 2 March trips, April 4 passengers, May 2 times, 7, September and 1 times. After the attack the army lO 1 person 2 times in 1 attack, attack 3 times 1. Joined the army before the army after the first 2 years and no disease. 2 Clinical and laboratory examination and treatment of blood pressure, pulse normal, conscious, able to describe in detail after onset; one complaint after hospital chest tightness, limp gas,[link widoczny dla zalogowanych], 11 cases still check tonic spasm or twitching limbs, but the passive to do the slow flexion exercise, massage can reduce symptoms; 1 case of peripheral limbs, decreased pain and temperature sensation. Neck soft,[link widoczny dla zalogowanych], physiological reflex exists, does not lead to the pathological. tk,[link widoczny dla zalogowanych], electroretinogram showed sinus arrhythmia and / or sinus bradycardia in 2 patients + with Q-T interval prolongation 1 case, with serum potassium, sodium, magnesium and lower 1 case, ketone (+4 ) 1 case, and myocardial enzymes, liver and kidney function,, T4, glucose, serum calcium were normal. As conditions, it was not to do blood gas analysis. 3 According to the clinical diagnosis and treatment information, patient incentives that are the same incidence of long-distance cross-country trained to paroxysmal dyspnea, with chest tightness, vomiting, flaccid paralysis, or general weakness, limb numbness, limb tonic seizures or convulsions as main features of the previous episode of non-similar, no heart,[link widoczny dla zalogowanych], brain, lung, kidney and other organic diseases, indications, hyperventilation syndrome were considered for the hospital to give body to explain the occurrence and local physical therapy and the principles and preventive measures that reduce the psychological burden of patients, all patients were discharged after 1-7d. 4 Analysis and discussion of long-distance cross-country training is the regular army physical training courses. Recruits in training, prone to hyperventilation syndrome, consider the following factors: (1) poor health. L2 patients in this group were new recruits and female, of which 75 towns recruits membership. O% (9/l2). This is mainly female and urban membership usually the lack of new recruits with strength, endurance exercise, poor physical fitness-related; and veterans through the forces of intensive training, physical fitness has been strengthened. (2) psychological difference. Long-distance cross-country training, only emphasizes speed, especially in the evaluation, some recruits worried about failing or poor performance drag collective hind legs, eager to win, physical fitness and poor, have over physical training. (3) improper training methods. Some recruits master the essentials of good action in the intensive training, there was no attention to the pace, swing arm and the coordination of breathing, or start too fast, premature fatigue, but can only mouth breathing, super-physical training and to hyperventilation. Rare incidence of veterans because of their physical strength, motor coordination, a pretty good idea of their own achievements, they are able to do hurry, better trained task. Exercise-induced hyperventilation is a major cause of respiratory alkalosis respiratory alkalosis can directly enhance neuromuscular excitability, the effect may be the reason causing convulsions, severe respiratory alkalosis can produce confusion or loss. The group 3 patients had transient confusion. And check the blood sugar is normal, which may be caused by hypocapnia on cerebral vasospasm (see WilsonJD editor. Harrison internal medicine (12th edition, the book). Beijing: People Health Press, 1994.351.) Liuzhou area from January to April average temperature 24qC. This group of patients treated, largely concentrated in the incidence from 1 April, the number of the total incidence of 73.3% (11/15),[link widoczny dla zalogowanych], so you can rule out the possibility of heat stroke.
