  • Clinical Application of Intra-Abdominal Pressure Measure in Patients with Liver Transplantation

    Objective To investigate the clinical significance of intra-abdominal pressure measure in patients with liver transplantation by summarizing the data of 143 cases. Methods Intra-abdominal pressure was indirectly measured by urinary bladder pressure. Intra-abdominal pressure over 10 cm H2O (1 cm H2O=0.098 kPa) was regarded as intra-abdominal hypertension (IAH), and 10<pressure≤15 cm H2O as gradeⅠ, 15<pressure≤25 cm H2O as grade Ⅱ, 25<pressure≤35 cm H2O as grade Ⅲ, over 35 cm H2O as grade Ⅳ. The parameters of circulatory system, respiratory system, renal function and the postoperative intra-abdominal pressure for 7 days were recorded to every patient, and the parameters of each grade IAH group were contrasted with non-IAH group. ResultsAmong 143 cases, 45 cases were IAH (31.5%), in which 18 cases belonged to grade Ⅰ, 13 cases belonged to grade Ⅱ, 11 cases belonged to grade Ⅲ, while 3 cases belonged to grade Ⅳ. Compared with those in non-IAH group, SCr and BUN significantly increased (P<0.05, P<0.01), PaO2 significantly decreased (P<0.05, P<0.01) in each grade IAH group; Respiratory frequency (RF), heart rate (HR) and PaCO2 significantly increased (P<0.05, P<0.01) in some grade IAH group (HR in grade Ⅱ, Ⅲ and Ⅳ, RF and PaCO2 in grade Ⅲ and Ⅳ). Conclusions Intra-abdominal hypertension would affect liver function by impaired circulatory, respiratory and renal function. So, it is necessary to measure intra-abdominal pressure for patients after liver transplantation, which can help to choose appropriate treatment.

  • 危重患者腹内压监测及腹腔高压对预后的影响

    随着医疗技术的提高, 医院的治疗手段越来越复杂, 越来越多的人接受复杂、疑难手术。住院的危重患者比例不断提高, ICU危重病患者中相当一部分发生多器官功能不全综合征( MODS) , 是导致ICU 患者死亡的首要原因[ 1] 。美国17 449例ICU 患者的统计调查结果显示, MODS 患病率为14% [ 2] , 其病死率为53. 5% [ 3] 。胃肠道功能衰竭是MODS中的一个组成部分, 是感染、创伤、休克等最早受损的器官之一。胃肠道功能衰竭合并MODS, 病死率更进一步增高达70% [ 4] 。危重患者一旦发生胃肠功能损害, 可因肠道内毒素细菌移位导致或加重其他器官损害, 引起肠源性脓毒症。及早发现和正确处理胃肠道功能损害, 是防治MODS 的研究方向, 对降低MODS 患者病死率具有重要意义。因此寻找早期胃肠道功能损害的诊断指标及预后指标尤为重要, 早期检出并动态监测胃肠道功能变化并准确的预测预后, 是治疗危重患者的重大挑战。

  • Effects of Different Levels of Intra-Abdominal Pressure on Hemodynamics and Oxygen Metabolism in Pig

    Objective To study the effects of different levels of intra-abdominal pressure (IAP) on hemodynamics and oxygen metabolism in pig and to find the parameters early reflecting hemodynamics and oxygen metabolism of intra-abdominal hypertension (IAH). Methods Fifteen pigs were anaesthetized, and trachea intubation and transfemoral cannula were performed then. Swan-Ganz catheters were inserted to pulmonary artery via internal jugular vein, and aeroperitoneum was set up by airing CO2. These pigs were randomly divided into three groups (5 pigs in each group) according to different levels of IAP (IAP10, IAP20, IAP30). Hemodynamics and oxygen metabolism values were observed and recorded before airing, 6, 12, 18 and 24 hours after airing, respectively. Results There was no remarkable changes of hemodynamics and oxygen metabolism values in IAP10 group (Pgt;0.05); When the IAP level reached 20 cm H2O, there was significant elevation (P<0.01) in artery blood lacticacid (ABL), and mixed venous oxygen saturation (SvO2) decreased significantly (P<0.05) at 24 hours. When the IAP level reached 30 cm H2O, HR began to increase significantly at 18 hours after airing (P<0.05). After 24 hours, all the indices of hemodynamics and oxygen metabolism were either significantly increased or decreased in IAP30 group. Two pigs in the group of IAP30 died during 24 hours after airing, while other pigs survived. Conclusion This study demonstrates that the hemodynamics and oxygen metabolism values begin to change in pigs when the IAP level reaches 20 cm H2O, and high level of IAP that lasted for 24 hours shows deterioration of hemodynamic and oxygenation levels. The indices of SvO2 and ABL can early reflect tissue oxygenation in IAH.

  • Clinical Study of Indwelling Catheters in Patients with Severe Acute Pancreatitis

    【Abstract】ObjectiveTo study the therapeutic effects of indwelling catheters in patients with severe acute pancreatitis (SAP). MethodsThe clinical data of 113 patients with severe acute pancreatitis admitted to our hospital from Aug. 2002 to May 2004 were collected. The patients were divided into the indwelling catheter group (45 cases) and the control group (68 cases).The APACHEⅡscores and therapeutic results were compared. The drainage and intraabdominal pressure (IPA) were monitored. Results The APACHEⅡscores on day 2 and day 5 after therapy in indwelling catheter group were significantly decreased compared with the control group(P=0.000).The average hospital stay and cyst morbidity of the indwelling catheter group were significantly decreased compared with those of the control group(P=0.000). The mortality rate was lower in the indwelling catheter group, but there was no statistical difference between these two groups(Pgt;0.05). The IAP was positively correlative with the drainage volume, hospital day and APACHEⅡscores(r=0.552, r=0.748, r=0.923,P=0.000). ConclusionThe indwelling catheter is an important treatment in patients with SAP.

  • PiCCO联合腹内压实时监测在危重患者中的应用及相关性分析

    目的探讨同步观察脉搏指示连续心排出量(PiCCO)和连续腹内压监测技术在ICU危重患者中的联合应用, 对二者的相关性进行分析。 方法我院普外科ICU病房2014年1月至2015年6月收治并同时进行了PiCCO和腹内压实时监测的危重患者共8例, 通过建立PiCCO监测通道以及腹腔内低顺应性毛细测压管, 记录患者进入ICU病房3 d内每隔8 h同步监测PiCCO所测得的连续心排出量(PCCO)以及腹腔内直接测压法所测得的腹内压。 结果8例患者术后3 d内每8 h同步记录的PCCO及腹内压共72个记录点的数据进行排除患者因素的偏相关性分析, 所得相关系数R=-0.682(P < 0.001)。 结论危重患者的腹内压与PCCO间存在显著的负相关性, 同步监测有利于更全面地掌握患者病情, 值得在临床中进一步应用和探索。
