Objective To summarize the blood supply to the sources and characteristics of advanced breast cancer，and explore the method，efficacy，and clinical applications of preoperative super-selective arterial catheterization chemoembolization under DSA for it. Methods Sixty patients with advanced breast cancer confirmed by the aspiration biopsy from February 2007 to October 2011 in this hospital were selected. Seldinger method was used，distributing of the tumor blood supply artery was identified and intubated the target artery by super-selective arterial catheterization via the femoral artery puncture under the DSA. Then，pirarubicin 60 mg plus paclitaxel 120 mg of two chemotherapy drugs was injected into slowly the target artery and the intervention infusion chemotherapy was performed，finally the tumor blood supply artery was embolizated by gelatin sponge particle. Results A total of 112 conclusive blood supply artery in 60 patients with DSA were found，including eight cases of single blood supply artery，52 cases of multiple blood supply arteries，mainly in the lateral thoracic artery and （or） internal thoracic artery-based. The complete remission rate was 25.0% （15/60），partial remission rate was 73.3% （44/60），stable disease rate was 1.7% （1/60），the total effective rate was 98.3% （59/60）. There was no progression disease. The median remission duration was 19 months，median survival time was 40 months. Conclusions The location of the original foci of breast cancer is closely related to blood supply arteries. The tumor in the lateral of the breast mainly dominates by the lateral thoracic artery blood supply. The tumor in the inner breast mainly dominates by the internal thoracic artery blood supply. The preoperative super-selective arterial catheterization chemoembolization under DSA can obviously improve the therapeutic effect，long-term survival，and the target of interventional chemoembolization.
ObjectiveTo investigate the application value of noninvasive ventilation (NIV) performed in patients with unplanned extubation (UE) in intensive care unit (ICU).MethodsThis was a retrospective analysis. The clinical data, application of NIV, reintubation rate and prognosis of UE patients in the ICU of this hospital from January 2014 to December 2018 were reviewed, and the patients were assigned to the control group or the NIV group according to the application of NIV after UE. The data between the two groups were compared and the application effects of NIV in UE patients were evaluated.ResultsA total of 66 UE patients were enrolled in this study, including 44 males and 22 females and with an average age of (64.2±16.1) years. Out of them, 41 patients (62.1%) used nasal catheter or mask for oxygenation as the control group, 25 patients (37.9%) used NIV as the NIV group. The Acute Physiology andChronic Health EvaluationⅡ score of the control group and the NIV group were (18.6±7.7) vs. (14.8±6.3), P=0.043. The causes of respiratory failure in the control group and the NIV group were as follows: pneumonia 16 patients (39.0%) vs. 7 patients (28.0%), postoperative respiratory failure 7 patients (17.1%) vs. 8 patients (32.0%), chronic obstructive pulmonary disease 8 patients (19.5%) vs. 6 patients (24.0%), others 5 patients (12.2%) vs. 4 patients (16.0%), heart failure 3 patients (7.3%) vs. 0 patients (0%), nervous system diseases 2 (4.9%) vs. 0 patients (0%), which showed no significant difference between the two groups. Mechanical ventilation time before UE were (12.5±19.8) vs (12.7±15.2) d (P=0.966), PaO2 of the control group and the NIV group before UE was (114.9±37.4) vs. (114.4±46.3)mm Hg (P=0.964), and oxygenation index was (267.1±82.0) vs. (257.4±80.0)mm Hg (P=0.614). Reintubation rate was 65.9% in the control group and 24.0% in the NIV group (P=0.001). The duration of mechanical ventilation was (23.9±26.0) vs. (21.8±26.0)d (P=0.754), the length of stay in ICU was (34.4±36.6) vs. (28.5±25.8)d (P=0.48). The total mortality rate in this study was 19.7%. The mortality rate in the control group and NIV group were 22.0% and 16.0% (P=0.555).ConclusionPatients with UE in ICU may consider using NIV to avoid reintubation.
ObjectiveTo investigate the feasibility and safety of non-intubation anesthesia in thoracic surgery.MethodsFrom September 2017 to December 2019, 296 patients were operated at department of thoracic surgery in our hospital. There were 167 males and 129 females with an average age of 50.69±12.95 years, ranging from 16 to 76 years. The patients were divided into two groups according to whether they were intubated: 150 patients were in a non-intubation group, including 83 males and 67 females with an average age of 49.91±13.59 years, ranging from 16 to 76 years, and 146 patients were in an intubation group including 84 males and 62 females with an average age of 51.49±12.26 years, ranging from 16 to 74 years. Intraoperative data, postoperative recovery, inflammatory response of the two groups were compared.ResultsThere was no statistical difference between the two groups in operation time, blood loss, the lowest oxygen saturation or other indicators (P>0.05). But the highest partial pressure of carbon dioxide of the non-intubation group was higher than that of the intubation group (P=0.012). The non-intubation group was superior to the intubation group in postoperative recovery and inflammatory response (P<0.05).ConclusionThe non-intubation anesthesia is safe and maneuverable in thoracic surgery, and it has some advantages in accelerating postoperative rehabilitation.
ObjectiveTo investigate the application of ascending aorta cannulation and brachiocephalic trunk cannulation in acute type A aortic dissection.MethodsWe screened 183 patients with acute type A aortic dissection from January 2017 to January 2020 in our hospital. They were divided into 2 groups according to the cannulation strategy: ascending aorta cannulation and brachiocephalic trunk cannulation (a DAC group, n=42, 33 males and 9 females with a median age of 50 years) and the single axillary artery cannulation (an AAC group, n=141, 116 males and 25 females with a median age of 51 years). The general clinical data, intraoperative data and early postoperative results of the two groups before and after matching with propensity scores were compared.ResultsBefore propensity-score matching, the operation time, cardiopulmonary bypass time, aortic occlusion time and ICU stay in the DAC group were all shorter than those in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications, renal failure and pulmonary complications in the DAC group were significantly lower than those in the AAC group. After propensity-score matching, the operation time in the DAC group was significantly shorter than that in the AAC group (P<0.05). The early postoperative mortality, and rates of brain complications and pulmonary complications in the DAC group were significantly lower than those in the AAC group.ConclusionAscending aorta cannulation and brachiocephalic trunk cannulation can provide a safe, fast and effective method of establishing cardiopulmonary bypass for some acute type A aortic dissection patients, and significantly shorten the operation time without increasing surgical complications.
Objective To study the application, safety and efficiency of tetracaine sprayed through thyrocricoid puncture before intubation in intensive care unit ( ICU) . Methods Forty-one patients ready to undergo intubation, admitted in ICU from November 2009 to February 2010, were recruited in the study. They were randomly divided into a tetracaine group and a control group. 2% tetracaine was sprayed through thyrocricoid puncture before intubation in the tetracaine group but not in the control group. The hemodynamic variables and SpO2 at baseline ( T0 ) , beginning of intubation ( T1 ) , 1 min after intubation ( T2 ) , and 5 min after intubation ( T3 ) were recorded. The dosage of propofol and vasoactive agents, the incidence of hypotension, the times of intubation, and complications were also recorded. Results The variance rate about heart rate ( HR) , mean arterial pressure ( MAP) and rate pressure production on time of T1 and T2 were significantly lower in the tetracaine group than those in the control group ( P lt; 0. 05) . There was no difference about the incidence of successful intubation and hypoxia ( P gt; 0. 05) . The dosage of propofol during induction and vasoactive agents after intubation in the tetracaine group were less than those in the control group ( P lt;0. 05) . The incidence of hypotension after intubation in the tetracaine group was 35% , which was lower than 61. 9% in the control group ( P lt;0. 05) . There was no any complications and adverse accidents in the tetracaine group. Conclusions It is safe and simple to spray tetracaine through thyrocricoid puncture before intubation in ICU, which can effectively stabilize the hemodynamics, and decrease the dosages of propofol and vasoactive agents.
