血压:收缩压小于90毫米汞柱和(或)脉压差小于30毫米汞柱卧床休息,头低位。开放气道并保持通畅,必要时气管捕管建立大静脉通道、紧急配血备血大流量吸氧,保持血氧饱和度95%以上监护心电、血压、脉搏和呼吸留置导尿/中心静脉置管测中心静脉压(CVP),记每小时出入量(特别是尿量)镇静:地西泮5~10毫克或劳拉西泮1~2毫克肌肉注射或静脉注射如果有明显的体表出血应尽早外科止血,以直接压迫为主 Blood pressure: systolic blood pressure less than 90 mmHg and / or pulse pressure difference less than 30 mm Hg bed rest, head low. Open the airway and keep it open. Tracheal trachea should be established to establish a large venous access if necessary. Blood is supplied urgently with a large amount of blood to maintain oxygen saturation. Over 95% of the oxygen saturation is monitored. Blood pressure, pulse, and indwelling catheterization / central venous catheterization Set the measured central venous pressure (CVP), remember the amount of each hour (especially urine output) sedation: diazepam 5 ~ 10 mg or lorazepam 1 ~ 2 mg intramuscular or intravenous injection if there is a clear body surface Bleeding should be as soon as surgical bleeding to direct oppression-based
