Objective To investigate change of bispectral index(BIS) and hemodynamic index during induction and orotracheal intubation of sevoflurane anesthesia. Methods This study was a prospective before-after study in the same patients. A total of 30 ASA physical status I and II adult patients without airway abnormalities were enrolled to receive inhalation induction of anesthesia with 8% sevoflurane. Mean arterial pressure(MAP),heart rate(HR) and BIS were recorded before anesthesia(T1),when patients loss of consciousness(T2), before intubation (T3),at 1 min(T4) and 3 min(T5) after intubation. Results BIS at T1-T5 were 96.8±1.7,70.4±8.8,39.2±8.4,43.6±12.9 and 41.6±9.3 respectively, the measurements at T2-T5 were all markedly lower than at T1(Plt;0.05). HR at T3-T5 were all markedly higher than at T1(Plt;0.05). MAP at T2 and T3 were markedly lower than at T1, but at T4 was higher than at T1(Plt;0.05), and recovered to the level at T1 at T5(Pgt;0.05).BIS,HR and MAP at T4 were all significantly higher than T3(Plt;0.05). Conclusion Anesthesia induction with sevoflurane and small dose of succinylchoiline we used can provide adequate depth of general anesthesia,but can not prevent cardiovascular adverse reactions to intubation.
【摘要】 目的 观察右星状神经节阻滞（R-SGB）对全身麻醉气管内插管期心血管反应的影响。 方法 2009年10-12月选取60例美国麻醉医师协会（ASA）Ⅰ、Ⅱ级择期全麻手术患者，随机分为3组。研究组于全麻诱导前15 min用1%利多卡因10 mL经颈6入路行R-SGB，对照组1诱导前同法注射10 mL生理盐水，对照组2诱导前肌注2%利多卡因5 mL。观察气管插管前后收缩压（SBP）、舒张压（DBP）、平均动脉压（MBP）、心率（HR）、心电图（ECG）、氧饱和度（SpO2）和心率收缩压乘积（RPP）的变化。 结果 研究组各时点与进入手术室时的基础值比较，仅诱导后SBP、DBP、MBP显著降低，窥喉时HR和RPP显著升高（Plt;0.01）；在插管3 min后已恢复至基础值。对照组1和对照组2诱导后SBP、DBP、MBP显著降低（Plt;0.01）；窥喉时SBP、DBP、MBP、HR、RPP均显著升高（Plt;0.01），并持续至插管后5 min。两对照组升高的程度均显著高于研究组（Plt;0.05或Plt;0.01）。 结论 R-SGB对全麻气管插管期的心血管反应有一定抑制作用，可用于调控全麻插管期心血管不良反应。【Abstract】 Objective To explore the effect of right stellate ganglion block (R-SGB) on cardiovascular response during endotracheal intubation under the general anesthesia. Methods Sixty ASAⅠ-Ⅱpatients who underwent general anaesthesia between October to December 2009 were randomly divided into three groups. The patients in the trial group accepted R-SGB by C6 route with 1% lidocaine (10 mL) 15 minutes before induction of general anesthesia; the patients in control group 1 were injected with 10 mL physiological saline in the same way before the induction; the patients in control group 2 underwent the intramuscular injection of 2% lidocaine (5 mL) before the induction. The changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hear rate (HR), electrocardiogram (ECG), oxygen saturation (SpO2) and heart rate-systolic blood pressure product (RPP) before and after endotracheal intubation were observed and recorded. Results In the trial group, SBP, MAP, and DBP decreased significantly after the induction; HR and RPP increased evidently at the laryngeal exposure compared with the baseline values (Plt;0.01) and recovered three minutes after the intubation. In the control group 1 and 2, SBP, MAP, and DBP decreased significantly after induction (Plt;0.01); SBP, MAP, DBP, HR and RPP increased apparently at the laryngeal exposure compared with the baseline values (Plt;0.01), and the raise continued until five minutes after endotracheal intubation. The difference in the raise between the control groups and the trial group was significant (Plt;0.05 or Plt;0.01). Conclusion R-SGB may effectively inhibit the cardiovascular response during endotracheal intubation under the general anesthesia and can be used to control the negative reaction during the induction.

Methods:Two hundreds and thirtyseven cases of severe respiratory failure were divided into two groups at random (fiberoptic bronchoscope group and laryngoscope group), 125 cases were intubated through mouth under fiberoptic bronchoscope, the others were intubated through mouth by laryngoscope. Results: The successful rates of endotracheal intubation were 98.4% and 92.0% in two groups respectively (P ＜005), the mean intubation timewere (613±391) min and (926±415) min respectively ( P ＜ 005), 4 cases in fiberoptic bronchoscope group appeared a little blood in throat, the complication rate was 32% 12 cases in the laryngoscope group had complications, the complication rate was 107%( P＜ 005). Among it, 6 cases had the injury of tooth, tongue, gullet and larynx.The cases of reflexvomiting were 2,pulmonary ventilation by single lung were 1, intubation in esophagus were 2, cardiopulmonary arrest were 1.Conclusions:Endotracheal intubation under fiberoptic bronchoscope through mouth was accurate, the fewer complications and effective for patients, and could be used widely in clinical applications.
目的：比较常规鼻胃管置入法与鼻咽部局部喷雾麻醉后置胃管法对喉癌患者的影响。方法：将需要安置胃管的100例患者随机分成两组，每组50例。实验组行鼻咽部喷雾麻醉，对照组按常规操作，比较两组患者流泪、恶心、呕吐、咳嗽反应，一次成功率及插管所需要时间、插入中暂停次数。结果：实验组一次成功率高，患者反应轻，插管所需时间有显著差异。结论：常规置胃管常因病员难受而中途暂停置管，实验组置胃管前先作鼻咽部局部喷雾麻醉，可明显减轻患者的痛苦，提高插胃管的一次成功率，插管过程中因病员难受暂停次数也明显减少，使临床护理工作时间缩短，对临床护理工作有积极意义。
The effects of preoperative selective arterial perfusion chemotherapy (PSAPC) in the treatment of 20 cases of histologically confirmed gastric cancers is reported in which 12 patients were operated on, and a comparison with that of general chemotherapy in 10 cases of gastric cancers (as controls) was made. In the PSAPC group, besides the improvement of clinical symptoms and singns, the cancer cells of lesions in situ and metastatic lymph nodes have different degrees of degeneration and necrosis. This result show significant differences in two group comparison (Plt;O.01). We conclude that the PSAPC has good short-term effect and little side-effect. It can improve the resection rate and radical resection rate, and prevent the iatrogenic metastasis and implantation during operation, and decrease the postoperative recurrence of the patients with gastric cancer.
Objective To evaluate the clinical features and complications of bedside tracheal intubation in intensive care unit ( ICU) , and explore the suitable strategy of intubation. Methods In this retrospective study,42 patients who underwent bedside tracheal intubation in ICU during September 2008 and March 2009 were divided into a schedule group ( n =24) and an emergency group ( n =18) . The time to successful intubation, number of intubation attempts, and complications were recorded. The schedule group was defined as those with indications for intubation and fully prepared, while the emergency group was defined as those undergoing emergency intubations without full preparation due to rapid progression of disease and accidental extubation. Results The success rate for all patients was only 57. 1% on the first attempt ofintubation. The main complications during and after induction were hypotension ( 45. 2% ) and hypoxemia ( 50. 0% ) . Compared with the emergency group, the schedule group had fewer attempts to successful intubation ( 1. 71 ±1. 12 vs. 2. 67 ±1. 75) , higher success rate on the second attempt ( 87. 5% vs.61. 1%) , and lower ypoxemia incidence ( 29. 1% vs. 77. 8%, P lt; 0. 05) . Conclusions The tracheal intubation in ICU is a difficult and high risk procedure with obvious complications. Early recognition ofpatients with indications and well preparation are critical to successful bedside intubation.
