ObjectiveTo investigate the situation of off-label drug use in dose (OLDUD) of ambroxol hydrochloride injection (AHI) in perioperative period among patients for stanford type A aortic dissection in Guangdong General Hospital, so as to provide references for the rational application of AHI in clinical practice. MethodsAll medical orders of AHI for patients had aortic arch replacement for Stanford type A aortic dissection in Guangdong General Hospital between January 2005 and December 2014 were included. The patients were divided into a mild OLDUD ( < 450 mg) group, a moderate OLDUD (450 mg≤OLDUD < 900 mg) group, and a high OLDUD (≥900 mg)group. The preoperative and postoperative features, incidence of PPCs, mortality, incidence of reintubation, time of mechanical ventilation, time stay in ICU, time stay in hospital and the overall costs among three groups were compared by SPSS 22.0 software. Resultsa) A total of 549 patients were included. The incidence of OLDUD was 99.82%. The most common PMDDs were 450 mg (n=358) and 900 mg (n=88). b) The three groups were well matched for perioperative and operative variables. c) The incidence of preoperative drug use was 8.6%. The incidences (5.5% vs. 7.7% vs. 15.7%, P=0.022) and maximum doses (180 mg vs. 300 mg vs. 450 mg, P=0.014) of preoperative drug use were statistically different in mild OLDUD, moderate OLDUD and high OLDUD groups. The days of preoperative drug use were not different (3 d vs. 2.5 d vs. 2 d, P=0.307). The days of postoperative drug use (9.5 d vs. 13 d vs. 19 d, P < 0.001) and postoperative drug use in maximum doses (7 d vs. 8 d vs. 7 d, P=0.005) were different. d) The incidence of PPCs was 100%, and the mortality (8.2% vs. 6.6% vs. 9.0%, P=0.696) was not statistically different among mild OLDUD, moderate OLDUD and high OLDUD groups. However the incidence of reintubation (14.3% vs. 13.8% vs. 27%, P=0.009), time of mechanical ventilation (37 h vs. 50 h vs. 114 h, P < 0.001), time stay in ICU (138 h vs. 178.5 h vs. 316 h, P < 0.001), time stay in hospital (25 d vs. 27 d vs. 34 d, P=0.001) and the overall costs (￥ 0.17 million vs. ￥ 0.19 million vs. ￥ 0.25 million, P < 0.001) were different among three groups. Moreover, they were all increasing along with the dose of AHI. ConclusionAHI cannot improve the prognosis of patients having aortic arch replacement for Stanford Type A Aortic Dissection in a dose-dependent manner. Further well-designed prospective studies should be conducted to verification or falsification.
Objective To establish a cooperative decision-making model of county-level public hospitals, so as to freely select the best partner in different decision-making units and promote the optimal allocation of medical resources. Methods The input and output data of 10 adjacent county-level public hospitals in Henan province from 2017 to 2019 was selected. Based on the traditional data envelopment analysis (DEA) model, a generalized fuzzy DEA cooperative decision-making model with better applicability to fuzzy indicators and optional decision-making units was constructed. By inputting index information such as total number of employees, number of beds, annual outpatient and emergency volume, number of discharged patients, total income and hospital grade evaluation, the cooperation efficiency intervals of different hospitals were calculated to scientifically select the best partner in different decision-making units.Results After substituting the data of 10 county-level public hospitals in H1-H10 into the model, taking H2 hospital as an example to make cooperative decision, among the four hospitals in H1, H2, H7 and H10 of the same scale, under optimistic circumstances, the best partner of H2 hospital was H7 hospital, and the cooperation efficiency value was 1.97; in a pessimistic situation, the best partner of H2 hospital was H10 hospital, and the cooperation efficiency value was 0.98. The model had good applicability in the cooperative decision-making of county-level public hospitals. Conclusion The generalized fuzzy DEA model can better evaluate the cooperative decision-making analysis between county-level public hospitals.
Objective To conduct a systematic review of the construction methods, predictive factors, and model quality of risk prediction models for postoperative chronic pain in knee replacement surgery patients, providing evidence for the development of nursing-sensitive dynamic prediction models. Methods A systematic review of risk prediction models for postoperative chronic pain in knee replacement surgery patients was conducted by searching PubMed, Web of Science, Cochrane Library, CINAHL, SinoMed, CNKI, Wanfang Database, and VIP Database. The search period was from the establishment of the databases to February 28, 2025. Two researchers independently screened the literature, extracted data, and assessed the risk of bias and applicability of the included studies. Results A total of 10 studies involving 10 predictive models were included in this review. Among these, three models underwent internal validation, and one model underwent external validation. Commonly reported predictive factors included postoperative 24-hour Numerical Rating Scale scores, postoperative knee function scores, sleep disorders, preoperative depression, postoperative functional exercises, postoperative complications, preoperative pain, and postoperative C-reactive protein levels. All 10 studies had a high risk of bias and were generally applicable. Conclusions Existing risk prediction models generally rely on static indicators and lack dynamic monitoring of postoperative rehabilitation behaviors and psychosocial factors, with severe deficiencies in model validation. Future research should focus on developing nursing-led multidimensional dynamic models that incorporate functional exercise adherence data collected via wearable devices, standardize external model validation, and enhance clinical translation value.
Objective To explore the operative safety of HIV-infected patients with colorectal cancer in different degrees of immunodeficiency. Methods A total of 56 patients, including 26 cases of HIV positive (HIV-positive group) and 28 cases of HIV negative (HIV-negative group), who underwent radical operation for colorectal cancer between January 2012 and December 2015, were enrolled in our study. We divided HIV-positive patients into three groups according to CD4+ T cells count in peripheral venous blood before 1 day (D0) of the surgery (HIV-positive Ⅰgroup with CD4+ T cells count >500/μL, HIV-positive Ⅱgroup with CD 4+ T cells count among 200–500/μL, and HIV-positive Ⅲ group with CD4+ T cells count <200/μL). Non-infective patients were enrolled in HIV-negative group. Leukocyte count, neutrophil percentage, lymphocyte percentage, CD 4+ T cells subsets count, and CD8+ T cells subsets count of the 4 groups in different time points were tested. In addition, we compared postoperative complications, carcinoembryonic antigen (CEA), and postoperative survival rate between the HIV-positive group and the HIV-negative group. Results In 56 cases, there were 26 cases of HIV-positive patients (including 10 cases of HIV-positive Ⅰ group, 8 cases of HIV-positive Ⅱ group and 10 cases of HIV-positive Ⅲ group). Variance results about repeated measurement data showed that, variation of leukocyte count, neutrophil percentage, lymphocyte percentage, and CD8+ T cells count among 4 groups after surgery had no statistical significance (P>0.05), in addition there was no significant on time effect and interactive effect of time and group (P>0.05). CD4+ T cells count in the 4 groups showed a trend from decline to rising with time going, and the time effect had statistical significance (P<0.05). The speed and amplitude of decline and recovery of CD4+ T cells count were different among groups, and the group effect had statistical significance (P<0.05). CEA showed a trend of decline after surgery in both HIV-positive group and HIV-negative group, and the time effect had statistical significance (P<0.05), but the group effect and interactive effect of time and group had no statistical significance (P>0.05). No statistically significant differences in amount of blood loss, duration of surgery, postoperative stay, nor complication rate (including incision infection, pulmonary infection, and opportunistic infections after surgery) were found between the HIV-positive group and the HIV-negative group (P>0.05). The overall survival situation of the HIV-positive group and the HIV-negative group had no statistical significance (P>0.05). Conclusions Radical operation for HIV-infected patients with colorectal cancer has an impact of " first inhibition and recovery” on cellular immunity over a period of time. Incidence of postoperative complications and survival rates are similar in HIV-positive patients and HIV-negative patients. In a word, it’s safe to have radical operation for colorectal cancer in HIV-positive patients under the proper perioperative treatment.
ObjectiveTo summarize the perioperative blood management strategies for joint arthroplasty. MethodsThe literature concerning preoperative, intraoperative, and postoperative blood management was reviewed and summarized. ResultsAt present, a variety of blood management and conservation strategies are available. Preoperative strategies include iron supplementation, erythropoietin (EPO), and preoperative autologous donation (PAD). Intraoperative options include acute normovolemic hemodilution (ANH), antifibrinolytics, and the use of a tourniquet. Postoperative strategies include the use of reinfusion systems and guided transfusion protocols. Preoperatively, administration of either simple EPO or a combination of EPO and PAD can be efficacious in anemic patients. Intraoperatively, tourniquet use and tranexamic acid can effectively control bleeding. Postoperatively, appropriate transfusion indications can avoid unnecessary blood transfusions. ConclusionPerioperative blood management strategies for joint arthroplasty should be integrated for the individual patient using a variety of ways to reduce perioperative blood loss and blood transfusion, and promote the rehabilitation of patients.
To investigate the causes and the cl inical treatment methods of postoperative wound compl ications following total knee arthroplasty (TKA). Methods From June 2005 to August 2008, 486 cases (576 knees, including 314 left knees and 262 right knees) underwent primary TKA using standard midl ine incision and medial parapatellar arthrotomy. There were 146 males (172 knees) and 340 females (404 knees) aged 51-86 years old (average 61.3 years old). The duration of disease was 3-35 years. Primary diseases included: 138 cases (156 knees) of rheumatoid arthritis, 282 cases (348 knees) of osteoarthritis, 46 cases (49 knees) of traumatic arthritis, 20 cases (23 knees) of pigmented villonodular synovitis. The factors of etiology, deformity correction, duration of tourniquet use and wound drainage were analyzed to determine the cause of postoperative wound compl ication. Results Postoperatively, 37 cases (43 knees) had wound compl ications and the rate of incidence was 7.5%, including 13 cases (15 knees) of aseptic exudation, 3 cases (4 knees) of fat l iquefaction, 4 cases (4 knees) of subcutaneous hematoma, 8 cases (9 knees) of flap margin necrosis, 6 cases (7 knees) of superficial infection, 3 cases (4 knees) of red swollen joint with increased skin temperature and deepinfection. All 37 patients recoveried after symptomatic treatment. Among those 37 cases, patients with rheumatoidarthritis had a higher incidence rate of wound compl ication than the patients with other primary diseases (P lt; 0.05). Theincidence rate of patients with deformity correction more than or equal to 20 degree was significantly higher than that ofother patients (P lt; 0.05). The duration of using tourniquet was (86 ± 15) minutes for patients with wound compl ication,and (78 ± 8) minutes for patients without wound compl ication, indicating there was a significant difference (P lt; 0.01).Wound compl ication occurred in 22 knees (5.1%) with autologous blood transfusion absorber, 11 knees (11.5%) withnegative pressure attraction, and 10 knees (19.2%) receiving no drainage. The incidence rate of postoperative woundcompl ication in patients without drainage was obviously higher than that in patients with drainage (P lt; 0.05). ConclusionPatients with rheumatoid arthritis are more l ikely to have wound compl ication after TKA. Postoperative wound drainage and short duration of tourniquet appl ication help decrease the incidence of compl ications. It is necessary to make early definitive diagnosis of postoperative wound compl ication, and provide proactive treatment.
In this paper, systematic reviews, randomized controlled trials and other relevant studies on surgical and adjuvant therapy following operative therapy in renal cancer were identified by searching the Guidelines International Network, ACP Journal Club, the Cochrane Library （Issue 3, 2005 ） , MEDLINE, EMBASE and CBMdisc （ from 1996 to Sept. 2005）. In operative therapy, we found no study comparing operative therapy with no treatment or adjuvant therapy alone; A meta-analysis of cytoreductive nephrectomy in patients with metastatic renal cancer showed adjuvant therapy following nephrectomy was more effective than adjuvant therapy alone; a review comparing radical nephrectomy with nephron-sparing surgery in small-volume renal tumors found similar effectiveness between the two procedures. In the adjuvant therapy following nephrectomy, ten RCTs found adjuvant cytokine therapy （Interferon and Interleukin-2 ） and 5-FU not effective in the adjuvant setting, and could increase adverse reaction; Four RCTs found adjuvant vaccine therapy effective in the adjuvant setting with only a few side effects.
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 understand the current progress of diagnosis and treatment of accidental gallbladder cancer.MethodThe relevant literatures about diagnosis and treatment of accidental gallbladder cancer and gallbladder cancer were analyzed and summarized.ResultsDue to the lack of specific symptoms and signs in most patients with accidental gallbladder cancer at the early stage, appropriate imaging examinations and tumor marker examinations could improve the preoperative diagnosis rate. The radical resection was the most effective method for accidental gallbladder cancer, but there were still some controversies about the scope of resection according to different tumor stages, the choice of laparoscopic cholecystectomy or open cholecystectomy, and the timing of reoperation. The postoperative adjuvant therapy could improve the prognosis of patients, but most patients didn’t receive adjuvant therapy after surgery.ConclusionsMost patients with accidental gallbladder cancer are in the early stage, and most of them could obtain radical resection. If the first operation fails to achieve radical resection or postoperative pathological examination to confirm the diagnosis, comprehensive evaluation of the tumor stage and the patient’s general condition should be performed, and remedial treatment should be taken as soon as possible.
