Bladder pressure, central venous pressure, systolic blood pressure and arterial blood oxygen partial pressure ( PaO2 ) were measured and compared before and after operation. 予以腹壁减张或开腹减压术者,监测其术后24h尿量、膀胱内压、中心静脉压、动脉收缩压、动脉血氧分压(PaO2),并与术前比较。
Most of patients were oliguric, with abnormal bladder pressure, central venous pressure, and systolic blood pressure 24 hours before operation. But these parameters were significantly improved after operation ( P0.01 ). 多数患者术前24h尿量偏少,膀胱内压、中心静脉压、动脉收缩压和PaO2表现异常,手术患者术后各项指标较术前明显好转(P0.01)。
Venous injection of 1mg / kg Doxazosin make the blood pressure of anesthetic SHR decrease rapidly and permanently, but no change significant in the EKG, heart rate and respiratory rate. lmg/kg多次唑嗪静脉注射使麻醉SHR血压迅速而持久下降,对心电图、心率和呼吸率无明显影响。
Endothoracic pressure and central venous pressure is so high to damage blood capillary, caused by higher intraabdominal pressure after pneumoperitoneum, is the mechanisms. 气腹致胸内压、中心静脉压过高,毛细血管过度充盈受损可能是眼结膜充血的发生机制。
After patients entering the operating room, venous puncture of upper limbs was done and then the lactated Ringer injection was dripped. Blood pressure, electrocardiogram, pulse oxygen saturation, and so on, were monitered, and their basic value was recorded. 患者入手术室后开放上肢静脉,静脉滴注乳酸钠林格氏液,连接监护仪,监测血压、心电图、脉搏氧饱和度等,并记录基础值。
