ABSTRACT
Abstract Introduction Ideal timing of Renal Replacement Therapy (RRT) discontinuation in Acute Kidney Injury (AKI) is still unknown. We aimed to study the role of creatinine-related variables in predicting RRT successful discontinuation and to propose a clinical predictive score. Methods In this single-centre retrospective study, we evaluated all AKI patients in whom RRT was interrupted for at least 48 hours. Patients who were still RRT-independent 7 days after initial RRT cessation were included in the "Success" group and opposed to the "Failure" group. We evaluated baseline characteristics and variables collected at the time of RRT interruption, as well as the Kinetic estimated Glomerular Filtration Rate (KeGFR), the simple variation in serum Creatinine (ΔsCr), and the incremental creatinine ratio on the first three days after RRT interruption. Multivariable analysis was performed to evaluate prediction of success. Internal validation using a simple binomial generalized regression model with Lasso estimation and 5-fold cross validation method was performed. Results We included 124 patients, 49 in the "Failure" group and 75 in the "Success" group. All creatinine-related variables predicted success in simple and multiple logistic regression models. The best model generated a clinical score based on the odds ratio obtained for each variable and included urine output, non-renal SOFA score, fluid balance, serum urea, serum potassium, blood pH, and the variation in sCr values after RRT discontinuation. The score presented an area under the ROC of 0.86 (95% CI 0.76‒1.00). Conclusion Creatinine variation between the first 2 consecutive days after RRT discontinuation might predict success in RRT discontinuation. The developed clinical score based on these variables might be a useful clinical decision tool to guide hemodialysis catheter safe removal.
ABSTRACT
Objective:To explore the effectiveness and complications of non-incision removal of tunneled cuffed catheter (TCC).Methods:The clinical characteristics, surgical plans and complications of patients with TCC removal in the Renal Division of Peking University First Hospital from January 1, 2015 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into non-incision removal group and traditional incision removal group. The clinical characteristics, procedure success rate, procedural duration and complications were compared between the two groups.Results:A total of 349 patients were included in this study, for whom 368 catheter removal procedures were performed, including 286 procedures in the non-incision removal group, 75 procedures in the traditional incision removal group, and 7 procedures without records of surgical plans. There was no significant difference in age, sex, basic kidney diseases and catheter remaining time and location between the two groups (all P>0.05). Two procedures in the non-incision removal group and 1 procedure in the traditional incision removal group failed respectively, and there was no significant difference in the procedure success rate between the two groups (99.3% vs 98.7%, χ2=0.290, P=0.590). The procedural duration in the non-incision removal group was lower than that in the traditional incision removal group [(5.36±1.70) min vs (17.55±3.28) min, t=44.198, P<0.001]. Among the patients who needed TCC exchange, there was no significant difference in the selection of new catheter position between the two groups ( P=0.330). In terms of complications, there were 2 procedures of local hematoma in the non-incision removal group and 1 procedure of infection in the traditional incision removal group, and there was no severe complication in both groups. Conclusions:There was no significant difference in the procedural success rate and complications between non-incision removal group and traditional incision removal group, and non-incision procedure may be superior in reducing the procedure duration and harm less to the patients. Non-incision procedure is a safe and effective method to remove TCC.
ABSTRACT
Objective:To investigate the effect of optimized catheter clipping training and automatic balloon retraction ureteral catheter removal on first urination of patients after neurosurgery, and provide guidance for postoperative micturition of these patients.Methods:From August 2020 to August 2021, 208 patients admitted to Department of Neurosurgery, the Affiliated Hospital of Xuzhou Medical University, undergoing craniocerebral surgery under general anesthesia and indurating catheter were selected as the study subjects by convenient sampling. They were divided into control group ( n=69), observation group A ( n=69) and observation group B( n=70) by random number table method. The control group received routine catheter clipping training and routine ureteral catheter removal, the observation group A received optimized catheter clipping training and routine ureteral catheter removal, and the observation group B received optimized catheter clipping training and automatic balloon retraction ureteral catheter removal. The first micturition time, first micturition volume, micturition circumstance, pain score and urethral irritation sign of the three groups were observed and compared. Results:The first urination time in observation group A and B were (11.58 ± 6.59) min and (10.06 ± 5.91) min, respectively, lower than (37.14 ± 13.74) min in control group, and the difference was statistically significant ( t=13.94, 15.07, both P<0.05); there was no significant difference between observation group B and observation group A ( P>0.05). The first urine volume were (303.66 ± 43.74) ml in control group, (299.06 ± 41.26) ml in observation group A and (299.28 ± 43.17) ml in observation group B, and the difference was not statistically significant ( P>0.05). The incidence of urination (spontaneous urination, induced urination and urinary retention) in observation group A was better than control group ( χ2=16.47), while observation group B was better than observation group A and control group ( χ2=8.59, 37.83), the differences were statistically significant (all P<0.05). There was no significant difference in pain score of ureteral catheter removal between observation group A (2.71 ± 0.67) and control group (2.87 ± 0.78) ( P>0.05). The score of observation group B (1.41 ± 0.65) was lower than that of control group and observation group A, the differences were statistically significant ( t=11.93, 11.62, both P<0.05). There was no significant difference of the incidence of urethral irritation (grade 0, 1, 2, and 3) between observation group A and control group ( P>0.05). Observation group B was lower than control group and observation group A, the differences were statistically significant ( t=38.81, 25.27, both P<0.05). Conclusions:Optimized catheter clipping training and automatic balloon retraction ureteral catheter removal can effectively shorten the first urination time of patients after neurosurgery, reduce the pain of ureteral catheter removal and urethral irritation during the first urination, improve the success rate of the first urination, and effectively prevent the occurrence of urinary retention.
ABSTRACT
Background and Objective@#Radical hysterectomy remains to be the first surgery for early‑stage cervical and selected stage 2 endometrial carcinoma. Functional disorders of the lower urinary tract are the foremost common complications following radical surgery necessitating catheterization. This study was undertaken to determine the number of postoperative days (POD) of the removal of urinary catheters after hysterectomy and assess the practicability of earlier removal of the catheter without compromising the bladder function@*Methodology@#A descriptive observational study of patients who underwent Type 2 or 3 hysterectomy for cervical or endometrial carcinoma. Clinical, intraoperative, and anesthesia records and results of the histopathologic reports of every patient were reviewed. Demographic, clinical, and histopathologic data needed during this review were recorded. Descriptive statistics were used.@*Results@#Between January 2016 and December 2019, a complete 45 patients underwent radical hysterectomy (43 patients for cervical cancer and a pair for endometrial carcinoma), with a median age of 50 years. The mean operative time is 2.5 h and also the average blood loss is 500 ml. The mean size of the cervical tumor was 2.2 cm, the mean length of the vagina was 2.5 cm, and the mean lateral width of parametria was 3.6 cm. Catheters were removed between the 3rd and 20th (mean = 6 days) POD. All patients had adequate spontaneous void within 6 h after removal. Five patients had their catheters removed beyond 7 days, 3 patients between POD 8 and POD 14, and 2 patients between days POD 15 and POD 20. All patients were able to return to bladder function within 3 weeks of catheterization.@*Conclusion@#The outcome showed that earlier removal of catheter seems to be a practical and safe option compared to long‑term catheterization for patients who underwent radical hysterectomy without causing morbidities

Fungal peritonitis is a rare but serious complication of peritoneal dialysis. This infection has been reported to be mostly caused by Candida species, and less frequently by a variety of other yeasts and moulds, such as Aspergillus, Penicillium, and Fusarium spp. are commonly isolated from soil, plants and environmental surfaces, and rarely from non-immunosuppressed subjects. In this report, author describe a case of infection caused by Fusarium solani in a 59-year-old man undergoing continuous ambulatory peritoneal dialysis. The fungus was recovered from cultures of peritoneal dialysate and the pathogen identification was carried out by mass spectrometry. The patient's outcome was favorable without complications after liposomal amphotericin B treatment along with peritoneal dialysis catheter removal.
ABSTRACT
Objective To evaluate evidence-based practice of catheter removal strategy in patients with short-term indwelling catheter after partial nephrectomy. Try to apply the best evidence into practice, and further to improvethe quality of clinical nursing through quality review. Methods Two rounds of quality review were carried out in the 2 wards from July to December in 2016. Using the 5 review criteria of best evidence, we reviewed baseline of catheter removal strategies for patients with short-term indwelling catheter after partial nephrectomy and developed appropriate evidence-based practice. Further, the best evidence was integrated into clinical nursing practice, and the prognosis was reviewed after then. Results In the baseline review, the compliance of the 5 review criteria was 0. However, after introducing the best evidence into nursing practice,the compliance was up to 100%. The mastering of evaluation knowledge of catheter removal of nurses increased from 73.00 ± 9.35 to 94.81 ± 3.38 with significant difference (t=12.72, P<0.01). The indwelling time of catheter shorted from (5.69±0.79) d to(4.24±0.82) d. The difference was significant (t=5.47, P<0.01). Conclusions Evidence-based nursing practice improvesthe strategies of short-term catheter removal after partialnephrectomy, while closer cooperation between nurses and doctors are still needed to promote the continuous improvement of nursing quality.
ABSTRACT
Air embolism can occur during central venous catheter removal. We encountered a patient diagnosed with cerebral air embolism associated with the removal of an internal jugular venous catheter. The patient was 65 years old and was admitted to the intensive care unit due to pneumonia. He had a catheter placed in the right internal jugular vein. Five days thereafter, the catheter was removed in semi-Fowler's position using the Valsalva maneuver. Immediately after the catheter removal, the patient became pale, felt dyspneic, lost consciousness and exhibited seizure activity. A neurological examination, revealed left upper arm (grade I) and lower leg paralysis (grade II) as well as left facial palsy. A brain computed tomogram showed that, air was trapped in the cavernous sinus. In diffusion weighted magnetic resonance imaging, signal changes were reported in the right frontal cortex, indicating acute cerebral infarction. Hyperbaric oxygen therapy and ventilatory support with synchronized intermittent mandatory ventilation mode was applied. Twenty days thereafter, consciousness and motor functions were recovered completely except for mild weakness of the upper arm (grade IV).

Objective To analyze the causes of non-elective removal of pereutaneously inserted central venous catheters (PICC) in premature infants. Methods We retrospectively collected the clinical data of 104 premature infants and analyzed the causes of non-elective removal of PICC. Results PICC was removed when the treatment was finished (n = 93, elective removal group) or due to complications ( n = 7, non-elective removal group). In non-elective removal group, the percentage of catheter tip located in the subclavian jugular was signifi-cantly higher in non-elective removal group than in the elective removal group (X2 = 24.931, P = 0. 000 ). The length of inserted catheter was ( 8.4 + 2.2 ) cm in the non-elective removal group and ( ( 10.2:1:1.6) cm in the elective removal group ( t = 3. 391, P = 0. 001 ). Conclusion The main cause of non-elective removal of cathe-ters in premature infants may be that catheter tip fails to reach the vena cava.
ABSTRACT
BACKGOUND: Recurrent peritonitis and catheter-related infection, in which removal of the PD catheter and temporary hemodialysis are required, are the main cause of limited technical survival in peritoneal dialysis (PD). The aim of this study was to verify whether the simultaneous catheter removal and replacement (SRR) is feasible and safe in patients with recurrent peritonitis and catheter-related infection. METHODS: From January 2001 to December 2004, We performed 47 SRR in 42 PD patients for the treatment of recurrent peritonitis and catheter-related infection to avoid the interruption of PD. RESULTS: Indications for SRR were recurrent peritonitis in 16 (34.0%), catheter infection without peritonitis in 16 (34.0%), catheter infection with peritonitis in 11 (23.5%) and peritonitis with dialysate leakage in 4 (8.5%). SRR was successful in 89.4%. However, SRR was failed in 10.6% due to persistent tunnel infection in three, drainage failure and hernia in each one. PD was continued after SRR during 14.5+/-11.8 months and subsequent catheter longevity ranged from 3 to 47 months. The most common causative organism of recurrent peritonitis and catheter-related infection was MRSA (25.5%). Subsequent peritonitis occurred in 52.4% of patients with the mean of 10.5+/-9.6 months after SRR. However, 81.8% of subsequent peritonitis were due to new organisms. Postoperative complications occurred in 16 cases (34.0%) including five cases with dialysate leakage, four with persistent tunnel infection, four with early peritonitis, two with drainage failure and one with bleeding. CONCLUSION: We conclude that SRR is a safe and effective procedure in patients with recurrent peritonitis and catheter-related infection without the interruption of PD.

Polymicrobial peritonitis is a relatively uncommon complication and it's clinical characteristics, risk factor and optimal managernent remain controversial. To identify indications for catheter removal in polymicrobial peritonitis, we reviewed the 340 episodes that occured in 168 patients of CAPD peritonitis during past 7 years to identify those. Polymicribial peritonitis was the 18 epoisodes in 18 patients of all peritonitis. First, 18 patients with polymicrobial peritonitis (P-P) did not show significant differences in the demographic features compared to 130 patients with single organism peritonitis (S-P). In contrast to Staphylococcus in S-P, the most common causative organisrn in P-P was pseudomonas (23%). Also sgnificantly more catheters were removed in P-P than S-P (P=0.001). Second, we cornpared group I, the patients responded to antibiotics only, and group II, those who needed catheter removal. The group I was 7 (39%) and the group II was 11 (61%). No patient of group I died and two patients of group II died. Between group I and group II, there were no significant differences in the demographic features. However, patients whose dialysate-WBC counts were below 100 at 3rd day after start of antibiotics were more significantly frequent in group I than group II. Among combination of causative organisms in P-P, most of Pseudornonas (6/9) and fungus (4/4) were treated by catheter removal. In conclusion, more catheters were removed in P-P than S-P. When dialysate WBC at 3rd day after start of antibiotics were over 100 and causative organism included pseudomonas or fungus in P-P, catheter removal was needed. We suggest that the kinds of organisms isolated and early response to antibiotics influence on the outcome of polymicrobial peritonitis.
