Objective To evaluate the impact of customized rehabilitation exercise plans based on the results of cardiopulmonary exercise test(CPET)on cardiac function and prognosis in patients with chronic heart failure(CHF).Methods A total of 52 CHF patients admitted to Chengde Central Hospital from February 2020 to September 2021 were selected as the study subjects,and the patients were divided into observation group and control group according to the principle of randomized controlled study,with 26 cases in each group.The control group received rehabilitation treatment excluding exercise.The observation group was given routine rehabilitation treatment and high-intensity rehabilitation exercise plans based on CPET guidance.Above anaerobic threshold Δ50%power was exercise intensity,exercise time was 30 minutes/day,4 days/week,and intervention period was 12 weeks.Before and 12 weeks after intervention,CPET functional indicators,serum brain natriuretic peptide(BNP),left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),and 6-minute walking distance(6MWD)were measured.The Minnesota CHF quality of life questionnaire(LiHFe)was used to evaluate patient's quality of life,readmission rate and cardiogenic mortality within 1 year of follow-up,and univariate and multivariate Logistic regression analysis was used to analyze factors affecting readmission of CHF patients.Results ① Cardiopulmonary function indicators:there was no statistically significant difference in the anaerobic threshold,peak oxygen uptake,and peak oxygen pulse of CPET functional indicators before and after intervention in the control group,after intervention,the CPET functional indicators in the observation group were significantly higher than those before intervention,and the above indexes in the observation group were significantly higher than those of the control group[anaerobic threshold(mL·min-1·kg-1):10.77±1.40 vs.9.59±1.11,anaerobic threshold(%ped):78.95±11.39 vs.70.09±6.48,peak oxygen uptake(mL·min-1·kg-1):15.63±1.36 vs.14.27±1.72,peak oxygen uptake(%ped):72.42±6.91 vs.63.41±7.31,peak oxygen pulse(mL/order):11.38±1.29 vs.9.05±1.64,peak oxygen pulse(%ped):90.23±10.16 vs.80.53±6.73,all P＜0.05].②Serum indicators,cardiac function indicators,exercise ability indicators,and quality of life evaluation:there was no statistically significant difference in serum indicators BNP,cardiac function indicators LVEDD,LVEF,exercise ability indicators 6MWD,and quality of life LiHFe scores between the two groups before intervention.After intervention,BNP and LiHFe scores were significantly reduced compared with before intervention,while LVEF and 6MWD were both increased compared with before intervention,and the changes of the above indexes in the observation group were more significant than those in the control group[BNP(ng/L):313.25±77.91 vs.445.89±110.67,LVEF:0.41±0.08 vs.0.37±0.06,6MWD(m):495.62±91.35 vs.416.04±65.29,LiHFe score:23.27±6.02 vs.29.50±4.61,all P＜0.05].③ Prognostic follow-up:the readmission rate within 1 year in the observation group was significantly lower than that in the control group(23.08%vs.53.85%),and there was no statistically significant difference in the mortality rate of cardiogenic diseases between the two groups.④Logistic univariate analysis showed that hyperlipidemia,New York Heart Association(NYHA)grading,BNP,and rehabilitation exercise were factors that affect the prognosis of CHF patients[odds ratio(OR)and 95%confidence interval(95%CI)were 0.098(0.019-0.494),0.069(0.016-0.294),1.018(1.007-1.029),and 3.889(1.178-12.841),respectively,all P＜0.05].Multivariate analysis showed that after adjusting for other factors,hyperlipidemia,NYHA grading,and BNP were risk factors affecting the prognosis of CHF patients(OR and 95%CI were 0.068(0.007-0.687),0.048(0.005-0.415),1.016(1.002-1.030),respectively,with P＜0.05],the use of rehabilitation exercise therapy was a protective factor affecting the prognosis of CHF patients[OR and 95%CI were 11.179(1.135-10.124),P＜0.05].Receiver operator characteristic curve(ROC curve)analysis showed that hyperlipidemia,NYHA grading,BNP,rehabilitation exercise therapy,and combined testing all had predictive value for the patient's prognosis(all P＜0.05),and the prediction value of joint detection was the highest,with the area under the ROC curve(AUC)=0.984 and P = 0.000.Conclusion Developing a high-intensity individualized cardiac exercise rehabilitation plan under the guidance of CPET can help improve the cardiopulmonary function,cardiac function,and quality of life of CHF patients,which is of great benefit for improving the long-term prognosis of CHF patients and has high safety.

ObjectiveTo compare the effectiveness and safety of one-lung ventilation and small tidal volume two-lung ventilation anesthesia methods in the training of minimally invasive thoracic surgery on experimental pigs.MethodsForty experimental pigs undergoing robotic thoracic surgery were randomly divided into two groups: two-lung ventilation group (n=20) and one-lung ventilation group (n=20). The two-lung ventilation group underwent single-lumen tracheal intubation, utilizing a small tidal volume with a fast respiratory rate combined with carbon dioxide pneumothorax for anesthesia ventilation during the operation. The one-lung ventilation group received one-lung ventilation using a double-lumen bronchial catheter placed under fiberoptic bronchoscopic guidance. The anesthesia implementation indexes from the two groups were compared, including the values of vital signs such as operative heart rate (HR), noninvasive mean blood pressure (MAP), end-tidal carbon dioxide (ETCO₂), and oxygen saturation (SpO₂), as well as the assessment of surgical training performance.Results The intubation success rate for animals in both groups was 100%, with no intraoperative deaths. The intubation completion time was significantly shorter in the two-lung ventilation group compared to the one-lung ventilation group (P < 0.001). Within each group, SpO₂ levels were significantly higher in the two-lung ventilation group at 30 minutes after the start of thoracic surgery (T₁) and at surgery completion (T₃) compared to 60 minutes after the start of surgery (T₂) (P<0.05). ETCO₂, HR, and MAP were significantly higher at T₂ and T₃ compared to T₁ (P<0.05). In the one-lung ventilation group, SpO₂ levels were significantly higher at T₁ and T₃ compared to T₂ (P<0.05), while ETCO₂ levels gradually increasing over time (P<0.05). In the between-group comparisons at the same time points, SpO₂ levels of the two-lung ventilation group were significantly higher than those of the one-lung ventilation group at all time points (T₁, T₂, T₃) (P<0.05).Conclusion Both one-lung ventilation and two-lung ventilation anesthesia methods are effective and safe for use in surgical training, with controllable effects on intraoperative animal vital signs and minimal impact on surgical operation training, meeting the needs of robotic thoracic surgery training. One-lung ventilation provides a better experience during pneumonectomy procedures, while small tidal volume two-lung ventilation is easier to implement and does not require additional equipment purchase, making it a feasible supplemental anesthesia option for thoracoscopic surgery on experimental pigs.

OBJECTIVETo study the key points of treatment and amputation in patients with frostbite, so as to increase the successful rate of the treatment.

METHODSFive hundred and sixty-eight patients with frostbite admitted to our department from January 2005 to December 2014. (1) For the patients admitted to our department within one week after injury, the frostbite wounds were soaked in 42 °C herbal fluid (twice per day, 30 min for each time) and irradiated with infrared or red light (three times per day, 40 min for each time) from the day of admission to the 7th day after injury. Meanwhile, treatment for improvement of microcirculation, vasodilation, and anti-infection were also given. Then they received infrared or red light irradiation to the wound sites. For the patients admitted to our department longer than one week after frostbite, the frostbite wounds were irradiated with infrared or red light, and treated with antibiotics if inflammation was found around the wound. Among all the patients, 5 cases suffered from frozen stiff, and they were given fluid resuscitation as well as above-mentioned treatments after admission. (2) All patients were given wound treatment immediately after admission. The superficial partial-thickness wounds and deep partial-thickness wounds of 264 patients were given routine dressing change. The full-thickness wounds in 79 patients were treated with exposure therapy after routine dressing change first, and then granulation tissue of these wounds were grafted with autologous thigh split-thickness skin grafts. After debridement and exposure therapy, amputation was done in 225 patients 3 to 4 weeks after injury when the underlying bone was exposed. In 4 patients with exposure of calcaneus, the wounds were covered with reverse sural nerve nutrient vessels island flap. Mean healing time of superficial partial-thickness wound and deep partial-thickness wound, survival rate of skin graft in full-thickness wound, and survival rate of flap covering wound deep to bone at the heel were all recorded. The amputation rate of patients injured in December, January, February, and other months, that of patients admitted shorter than 1 day after frostbite, 1 to 3 days after frostbite, longer than 3 days and shorter than or equal to 5 days after frostbite, and longer than 5 days after frostbite, that of patients caused by drunkenness, mental disorders, improper protection, going astray, and trauma including traffic accident etc., and that of patients treated with rewarming under room temperature, rubbing with snow, wrapping with quilt, and soaking in warm water before admission were all recorded and analyzed. Parts of the data were processed with χ(2) test.

RESULTSAll patients were survived after treatment. Average wound healing time of superficial partial -thickness wound and deep partial-thickness wound was respectively 10 and 23 days. The survival rate of skin graft on full-thickness wound was about 95%. Survival rate of flap on wound deep to bone at the heel was 100%. Amputation rates of patients injured in December and January were respectively 47.46% (84/177), 42.56% (103/242), and both were significantly higher than those of patients injured in February and the other months [respectively 29.55% (26/88), 13.11% (8/61), with χ(2) values from 42.595 to 220.900, P values below 0.01]. Amputation rate of patients with admission time shorter than 1 day after frostbite was 32.06% (84/262), which was obviously lower than that of patients with admission time from 1 to 3 days after frostbite, longer than 3 days and less than or equal to 5 days after frostbite, or longer than 5 days after frostbite [respectively 40.48% (68/168), 49.02% (50/102), 52.78% (19/36), with χ(2) values from 107.284 to 165.350, P values below 0.01]. Amputation rates of patients with frostbite occurring after getting drunkenness, mental disorders, and trauma including traffic accident etc. were respectively 42.06% (106/252), 43.48% (60/138), and 53.12% (17/32), and they were all significantly higher than those of patients with frostbite caused by improper protection and going astray [respectively 27.45% (28/102), 22.73% (10/44), with χ(2) values from 187.260 to 209.738, P values below 0.01]. Amputation rates of patients undergoing treatment of rewarming under room temperature, rubbing with snow, wrapping with quilt before admission were respectively 44.29% (62/140), 48.28% (84/174), and 35.38% (46/130), and they were significantly higher than the amputation rate of patients who received the treatment of soaking in warm water [23.39% (29/124), with χ(2) values from 97.364 to 136.189, P values below 0.01].

CONCLUSIONSEarly diagnosis and treatment, properly rewarming at early stage, and correct wound treatment are the key points for reducing amputation rate of patients after frostbite. Attention should be paid to the occurrence of frostbite in December and January, and also to protection of high-risk groups (patients with mental disorders and drunker).
