  • Clinical research on perioperative restrictive fluid therapy combined with preoperative urination training in total hip arthroplasty

    Objective To evaluate the effectiveness and safety of restrictive fluid therapy combined with preoperative urination training during perioperative period in an enhanced recovery after surgery (ERAS) program for primary total hip arthroplasty (THA). Methods A retrospective study were conducted in 73 patients who underwent unilateral THA with liberal intravenous fluid therapy on the day of surgery between April 2015 and March 2016 (control group) and in 70 patients with restrictive fluid therapy and preoperative urination training between November 2016 and April 2017 (trial group). There was no significant difference in gender, age, weight, height, body mass index, primary disease, and complications between 2 groups (P>0.05). Perioperative related indexes were recorded and compared between 2 groups, including operation time; pre-, intra-, post-operative intravenous fluid volumes, overall intravenous fluid volume on the surgery day; postoperative urine volume per hour after surgery; blood volume; total blood loss during perioperative period; usage rates of diuretics and urine tube; the incidences of hypotension, nausea and vomiting, hyponatremia, and hypokalemia after surgery; postoperative length of stay; and the expressions of inflammatory factors [C reaction protein (CRP), interleukin-6 (IL-6)] before sugery and at 1st and 2nd days after surgery. Results The pre-, intra-, post-operative intravenous fluid volumes and the overall intravenous fluid volume on the surgery day in trial group were significantly lower than those in control group (P<0.05). There was no significant difference in operation time, blood volume, total blood loss during perioperative period, and postoperative urine volume per hour after surgery between 2 groups (P>0.05). The usage rates of diuretics and urine tube in trial group were significantly lower than those in control group (P<0.05), while the differences in incidences of hypotension, nausea and vomiting, hyponatremia, and hypokalemia after surgery of 2 groups were insignificant (P>0.05). The level of inflammation factors (CRP, IL-6) at 1st and 2nd days was significant lower in trial group than in control group (P<0.05), with shorter postoperative length of stay (t=–5.529, P=0.000). Conclusion It is safe and effective to adopt restrictive fluid therapy and preoperative urination training during perioperative period (intravenous fluid volume controls in about 1 200 mL on the day of surgery) following ERAS in primary THA. However, prospective studies with large-scale are still in demand for further confirming the conclusion.

  • Comparison of refracture risk between sandwich vertebrae and ordinary adjacent vertebrae

    ObjectiveTo compare the refracture risk between sandwich vertebrae and ordinary adjacent vertebrae, and to explore the risk factors related to refracture.MethodsRetrospective analysis was performed on the data of patients who received percutaneous vertebral augmentation (PVA) and formed sandwich vertebrae between April 2015 and October 2019. Of them, 115 patients were enrolled in the study. There were 27 males and 88 females with an average age of 73.9 years (range, 53-89 years). Univariate analysis was performed to analyzed the patients’ general data, vertebral augmentation related indexes, and sandwich vertebrae related indexes. Survival analysis was performed for all untreated vertebrae at T4-L5 of the included patients at the vertebra-specific level, and risk curves of refracture probability of untreated vertebrae between sandwich vertebrae and ordinary adjacent vertebrae were compared. Cox’s proportional hazards regression model was used to analyze risk factors for refracture.ResultsThe 115 patients were followed up 12.6-65.9 months (mean, 36.2 months). Thirty-seven refractures involving 51 vertebral bodies occurred in 31 patients. The refracture rate of 27.0% (31/115) in patients with sandwich vertebrae was significantly higher than that of 15.2% (187/1228) in all patients who received PVA during the same period (χ2=10.638, P=0.001). Univariate analysis results showed that there was a significant difference in the number of augmented vertebrae between patients with and without refractures (Z=0.870, P=0.004). However, there was no significant difference in gender, age, body mass index, whether had clear causes of fracture, whether had dual energy X-ray absorptiometry testing, whether the sandwich vertebra generated through the same PVA, puncture method, method of PVA, number of PVA procedures, number of vertebrae with old fracture, whether complicated with spinal deformity, bone cement distribution, and kyphosis angle of sandwich vertebral area (P>0.05). Among the 1 293 untreated vertebrae, there were 136 sandwich vertebrae and 286 ordinary adjacent vertebrae. The refracture rate of sandwich vertebrae was 11.3% which was higher than that of ordinary adjacent vertebrae (6.3%)(χ2=4.668, P=0.031). The 1- and 5-year fracture-free probabilities were 0.90 and 0.87 for the sandwich vertebrae, and 0.95 and 0.93 for the ordinary adjacent vertebrae, respectively. There was a significant difference between the two risk curves of refracture (χ2=4.823, P=0.028). Cox’s proportional hazards regression model analysis results showed that the sandwich vertebrae, thoracolumbar location, the number of the augmented vertebrae, and the unilateral puncture were significant risk factors for refracture (P<0.05).ConclusionThe sandwich vertebrae has a higher risk of refracture when compared with the ordinary adjacent vertebrae, and its 1- and 5-year fracture-free probabilities are lower than those of the ordinary adjacent vertebrae. However, the 5-year fracture-free probability of sandwich vertebrae is still 0.87, so prophylactic enhancement is not recommended for all sandwich vertebrae. In addition, the sandwich vertebrae, thoracolumbar location, the number of the augmented vertebrae, and the unilateral puncture were important risk factors for refracture.

  • Construction of influence evaluation index system for key medical disciplines/specialties in Sichuan Province

    ObjectiveTo establish an evaluation index system suitable for key medical disciplines/specialties in Sichuan Province, with the coverage of tertiary-level comprehensive and tertiary specialty hospitals, and the provincial medical key disciplines/specialties as the starting point, so as to promote the development of key medical disciplines in Sichuan Province.MethodsThe literature method, expert meeting method, Delphi method, and analytic hierarchy process were used to establish the index system and the corresponding weights of each index.ResultsAn evaluation index system for the influence ranking of key medical disciplines/specialties in Sichuan Province was established, covering scientific and technological inputs and outputs, clinical services, and industry influence. The entire evaluation index system included 3 first-level indicators, 8 second-level indicators, 19 third-level indicators and corresponding weights.ConclusionThis evaluation index system has applied to rank the influence of key medical disciplines/specialties in Sichuan Province, laying a solid foundation for the influence evaluation of the key medical disciplines/specialties and the future platform construction in Sichuan Province.

  • Valve in Valve transcatheter mitral valve replacement by a transvenous, transseptal access: A case report

    Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.
