This article reports the management of thirty elderly patients of septic shock during anesthesia. Twenty-four of them received continious epidural anesthesia, five of them were under intravenous general anesthesia with endotracheal intubation, and onr patients recerived intravenous ketamine anesthesia. The effects of these patients on enesthesia wer satisfactory. Twenty-four patients recouverd after roperation. Six patients died. The authors atresses the high risk of anesthetic management in these patients. Experiences are introduced in per-anesthetic preparation and medication selection and maintenance of anesthesia, monitoring and treatment during anesthesia and postoperative care of septic shock of the elderly.
Objective To investigate the value of pulse indicator continuous cardiac output ( PiCCO) monitoring in the treatment of septic shock.Methods Patients with septic shock were selected in intensive care unit ( ICU) . After initial empirical resuscitating and using vasoactive drugs, the patients with circulation instability were connected with the PiCCO temperature probe to monitor hemodynamics and to resuscitate in the target of intrathoracic blood volume index ( ITBVI) , cardiac index ( CI) , extravascular lung water index ( EVLWI) . Hemodynamic parameters, oxygen metabolic variability and 24h-fluid management after 0h ( before) , 8h, 24h, the rate of implementing resuscitation goals, oxygen metabolic variability and fluid resuscitation at different times in the guidance of PiCCO parameters were compared. The data of age, APACHEⅡ score, central venous pressure ( CVP) , CI, ITBVI, mean arterial pressure ( MAP) , systemic vascular resistance index ( SVRI) and EVLWI after 0h and 24h were substituted into the regression equation by the multiple linear regression, to determine the indexes which would affect the 28-day prognosis. Results A total of 80 patients with septic shock were recruited in the study. Comparing fluid resuscitation at different times in the guidance of PiCCO,MAP( 73.6 ±13.4 and 75.1 ±10.2 mm Hg) , ITBVI ( 843.5 ±168.9 and 891.5 ±232.9 mL/m2 ) and CI ( 3.2 ±1.1 and 3.9 ±0. 4 L· min-1 · m-2 ) on 8h and 24h were significantly higher than that at 0h ( 69.1 ±21.4 mm Hg, 781.2±146.7 mL/m2 and 2.7 ±1.5 L·min-1·m-2 ) , and Lac( 2.0 ±1.4 and 1.1 ±1.0 mmol /L) and SVRI ( 1 624. 2 ±301. 7 and 1 543.6 ±435.4 d·s·m2·cm-5 ) were declined than that at 0h( 3.1 ±2.4 mmol /L and 1 796.2 ±399.1 d·s·m2 ·cm-5 ) ( Plt;0.05) . The rate of implementing resuscitation goals at 8h ( 64.7% ) and 24h ( 66.9% ) were significantly higher than that at 0h ( 55.7% ) ( Plt;0.05) , but there was no significant difference between 8h and 24h ( Pgt;0.05) . All of the patients were divided into a survival group ( n=54) and a death group ( n=26) . The rate of implementing resuscitation goals at 0h and 24h in the survival group ( 57.1% and 71.3% ) were significantly higher than that of the death group( 28.6% and 39.3% ) . By the prognosis on 28-day as the dependent variability in the multiple linear regression, multiple linear regression equation were established, and there was significantly difference ( F=55.03, Plt;0.05) . By the layer-wise screening, equation was fitted, both the CI ( R=0.431) and ITBVI ( R=0.627) at beginning and EVLWI ( R= 0.305) at 24h were determined to influence the 28-day prognosis. Conclusions The fluid resuscitation under the guidance of PiCCO can achieve the goal better and improve the prognosis. CI, ITBVI and EVLWI were useful goaldirectors for the prognosis evaluation in critical ill patients.
Objective To systemically review the efficacy and safety of dopamine versus norepinephrine in patients with septic shock. Methods Database searches of MEDLINE, EMbase, Cochrane Controlled Trials Register, VIP, CNKI, and CBM (from the date of database establishment to June 2011) were conducted. Additional studies for collecting relevant data were retrieved via both references of articles and direct contact with authors. Prospectively, randomized controlled trials (RCTs) of dopamine compared with norepinephrine therapy in septic shock patients were selected. The quality of included trials was assessed and relevant data were extracted. Then statistical analysis was performed using RevMan 5.1. Results Nine trials with 3 179 participants were included. The results of meta-analysis showed: compared with norepinephrine, dopamine was associated with a significant 12% elevation in the risk ratio of in-hospital death events of septic shock patients (RR=1.12, 95%CI 1.04 to 1.21, P=0.002). The risk of arrhythmias in dopamine group was 2.63-fold than that in norepinephrine group (RR=2.63, 95%CI 1.51 to 4.55, P=0.000 6). The cardiac index of septic patients in dopamine group was higher than that in norepinephrine group (MD=0.42, 95%CI 0.21 to 0.63, Plt;0.000 1). No significant difference could be found in the heart rate (MD=17.05, 95%CI –0.71 to 34.81, P=0.06) and mean arterial pressure (MD= –0.87, 95%CI –24.97 to 7.62, P=0.30). Conclusion Findings from this meta-analysis suggest that compared with dopamine, norepinephrine significantly reduces both 28-day mortality of septic shock patients and incidence rate of arrhythmias. Norepinephrine is better than dopamine in aspects of efficacy and safety.
目的 探讨孤立肾肾结石经皮肾镜取石（PCNL）术并发感染性休克的护理。 方法 回顾性分析2010年3月－2012年10月5例孤立肾肾结石患者行PCNL术后并发感染性休克的临床资料，对患者术后出现的休克及时补足血容量，使用有效的抗生素，早期足量应用激素、血管活性药物，同时加强心理疏导、健康教育等护理措施。 结果 5例患者体温均在3 d内降至正常；血管活性药物平均使用时间为1.8 d （2～4 d）；1例因血氧饱和度＜80%，血压＜85/50 mm Hg（1 mm Hg=0.133 kPa）转往重症监护病房行呼吸机辅助呼吸2 d后呼吸循环功能改善；另1例同时出现少尿无尿，及时行血液透析，第4天尿量逐渐恢复；5例患者均痊愈出院。 结论 感染性休克是PCNL术后最危险的并发症之一，对其采取积极预防、及早发现、及时有效的治疗和护理等措施，可有效促进患者康复。
目的 探讨早期碱剩余对感染性休克患者病情严重程度的预测价值。 方法 对2009年2月－2011年2月资料完整入院的感染性休克患者60例进行回顾性分析，按死亡及存活进行分组，对最初24 h的碱剩余值差异及血乳酸清除率情况进行对照研究。 结果 死亡组碱剩余值变化及乳酸清除率低于存活组（P＜0.05）。治疗后碱剩余≤−6 mmol/L较碱剩余＞−6 mmol/L的患者病死率明显增加，尤其是治疗后24 h 碱剩余仍≤−6 mmol/L病死率高达92.23%。 结论 早期碱剩余有助于感染性休克预后评估和指导临床治疗。

Methods From Janurary 2005 to December 2010, the clinical data of five patients with septic shock after percutaneous nephrolithotomy in our hospital were retrospectively analyzed. The patients, including one male and four females, had chillness and high temperature after the nephrolithotomy. The blood pressure decreased to under 80/50 mm Hg （1 mm Hg=0.133 kPa）, and the heart rate was more than 120 per minute. All patients underwent anti-shock and anti-infection therapies rapidly. Results Five patients were cured in the end, their temperature and blood routine tests returned to normal within one week. Conclusions Septic shock is one of the serious complications after percutaneous nephrolithotomy. Effective preoperative preparation, low pressure irrigation during operation, early diagnosis and treatment postoperatively are the effective ways to prevent the septic shock.
