ABSTRACT
Objective:The characteristics of bacteriology and the change of drug resistance in PICU of our hospital during recent 5 years were analyzed to guide clinical rational drug use.Methods:All positive results of bacterial culture in PICU from January 2016 to December 2020 were retrospectively analyzed, and were classified according to the sample source, strain type and drug sensitivity results.The bacterial etiology spectrum and drug resistance in PICU were summarized.Results:A total of 800 pathogenic bacteria were isolated from the specimens collected from the PICU from January 2016 to December 2020, including 476 Gram-negative bacteria, 292 Gram-positive bacteria, and 32 fungi, accounting for 59.50%, 36.50%, and 4.00%, respectively.The top 9 bacteria were: Staphylococcus aureus 134(16.75%), Haemophilusinfluenzae 79(9.88%), Klebsiellapneumoniae 78(9.75%), Streptococcus pneumoniae 74(9.25%), Escherichia coli 56(7.00%), Acinetobacterbaumannii 51(6.38%), Moraxella catarrhalis 48(6.00%), Enterobacter cloacae 26(3.25%), Pseudomonas aeruginosa 25(3.13%). Drug sensitivity results showed that 27(48.21%, 27/56)strains of EScherichia coli and 42(53.85%, 42/78) strains of Klebsiella pneumoniae were positive for ultrawide spectrum β-lactamase, and a total of 24(17.91%, 24/134)strains of methicillin-resistant Staphylococcus aureus were detected.Staphylococcus aureus was almost 100% resistant to penicillin G and ampicillin, and had high resistance rates to clindamycin and erythromycin(72.70% and 72.30%, respectively). It was 100% sensitive to minocycline, teicoranin, vancomycin, linezolid, and dattomycin.The drug resistance rates of Streptococcus pneumoniae to erythromycin and clindamycin were 98.60% and 98.50%, respectively.The drug resistance rates to azithromycin were 96.80%, the drug resistance rates to penicillin G, cefotaxime and ceftriaxone were 12.30%, 5.40% and 1.50%, respectively, and the drug resistance rates to moxifloxacin, linezolid and vancomycin were 100% sensitive.Conclusion:During the past five years, the etiology of the PICU in our hospital is mainly Gram-negative bacteria, and the most common pathogenic bacteria is Staphylococcus aureus.Klebsiella pneumoniae and Escherichia coli infections remain a great challenge.Bacterial resistance moitoring should be strengthened to provide evidence for the rational use of antibiotics.
ABSTRACT
【Objective】 To share the technical key points and experience of transvesical robot-assisted radical prostatectomy (TvRARP). 【Methods】 The clinical data of 13 patients with prostate cancer (PCa) receiving TvRARP during Nov.2021 and May 2022 were collected. The operation time, estimated blood loss, blood transfusion rate, catheter removal time, postoperative length of hospital stay, immediate urinary continence rate, postoperative IIEF-5 score and perioperative complications were evaluated. 【Results】 The operation time was (142±39) min, estimated intraoperative blood loss was (76±40) mL, and no transfusion was needed. The median postoperative IIEF-5 score was 16 (12-22), hospital stay 3 (2-5)days, and catheter removal time 7(5-14)days. Of all 13 patients, 12(92.3%) achieved immediate urinary continence at the removal of catheter. There were no postoperative complications of Clavien Ⅲ and above. Clavien Ⅰ-Ⅱ complications were observed in 4 patients (30.8%). 【Conclusion】 TvRARP is feasible and safe for selected patients with clinically localized PCa, which can ensure promising postoperative urinary continence and preserve erectile functional.
ABSTRACT
Objective To evaluate the safety,efficiency of retroperitoneal laparoscopic partial nephrectomy combined with four points location in 3D model or 3Dimensional CT for completely endophytic tumors,and summarize the surgical experience.Methods From Jan 2015 to Jan 2016,5 patients with completely endophytic tumors,who underwent retroperitoneal laparoscopic partial nephrectomy were recruited.one patient underwent 3D printing kidney model,and another 4 patients underwent 3Dimensional CT and locating four projection positions of the tumor on the surface,in order to guide the tumor resection in laparoscopic partial nephrectomy.Perioperative,operative,and postoperative,as well as oncological outcomes were analyzed.Results In all 5patients,preoperative four points location in 3D model or 3Dimensional CT for completely endophytic tumors is feasible and accurate in term of locating the tumor.The mean operative time was(129.0 ± 19.5) min,mean warm ischaemia time was (19.6 ± 5.4) min and mean estimated blood loss was(100 ± 83) ml.Pathological examination showed cell renal cell carcinoma.All the patients had a negative surgical margin,and no tumor recurrence or metastasis during 6-18months of follow up.Conclusions In experienced institutes,retroperitoneal laparoscopic partial nephrectomy combined with four points location in 3D model or 3Dimensional CT for completely endophytic tumors is a feasible and safe procedure in terms of accurate locations,low complication rates,reasonable functional and oncologic outcomes after an intermediate-term follow-up
