RESUMO

To explore the effect of homogenized nursing interventions for bladder irrigation after urological surgery in primary hospitals, and to further analyze the incidence of postoperative complications according to the different nursing methods. The experiment selected 110 patients with urological disorders who underwent bladder irrigation, and the subjects were admitted to the hospital from January 2020 to October 2023. The subjects were chronologically divided into a control group and an experimental group, with the admission time of the control group being between between January 2020 and October 2022. The experimental group was admitted between October 2022 and October 2023. Conventional nursing care and homogenized nursing care were used respectively, and the intervention effect of homogenized nursing care was assessed by comparing the patients' psychological state indexes, vital characteristic indexes, and the incidence of various postoperative complications under the 2 interventions. None of the indicators were statistically significant before the nursing intervention. In the comparison of nursing satisfaction and clinical comfort, the experimental group's nursing satisfaction was 94.5% and clinical comfort was 90.9%, which was significantly higher than that of the control group. In the comparison of the incidence of postoperative complications, the incidence of urinary retention in the experimental group was 1.82%, which was significantly lower than that of the control group. In addition, the total incidence of complications in the experimental group was 1.82%, which proved that the homogenized nursing intervention was effective in reducing the complications after urinary bladder irrigation. In multifactorial logistic regression analysis, after homogenized nursing intervention. The relative risks of the 4 complications were 1.836, 1.445, 1.993, and 2.138, respectively, which were significantly lower than those of conventional nursing intervention. In the ROC analysis, the AUC values of the 4 complications were 0.832, 0.731, 0.746, and 0.723, respectively. proving the superiority of homogenized care in preventing postoperative complications. Homogenized nursing intervention can effectively reduce the incidence of postoperative complications in patients with urological postoperative bladder irrigation, improve patients' symptoms and prognosis, and improve the quality of care and patients' quality of life.

RESUMO

PURPOSE: Diverting Loop Ileostomy (DLI) with intraoperative colonic lavage has emerged as a potential alternative to Total Abdominal Colectomy (TAC) for treating Fulminant Clostridium Difficile Colitis (FCDC). This study aims to provide an updated review comparing DLI with TAC in managing FCDC. METHODS: A systematic literature search was conducted using PubMed, Scopus, and Embase to identify retrospective and prospective studies comparing DLI with TAC for fulminant CDC treatment. A meta-analysis was performed to evaluate postoperative mortality rates and complications using R Studio version 4.4.1, calculating odds ratios (ORs) with 95% confidence intervals via the Mantel-Haenszel method. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. RESULTS: Our search yielded 228 relevant citations, of which 7 studies with a total of 7,048 patients were included. Of these, 1,728 underwent DLI. The mean age was 63.33 years in the DLI group and 65.74 years in the TAC group. Compared to TAC, DLI had significantly lower postoperative mortality (OR 0.75; 95% CI 0.62-0.90; P = 0.002; I2 = 34%). Trial sequential analysis for postoperative mortality rates showed the benefit of DLI with a sufficiently powered sample. The DLI group also had a significantly higher rate of ostomy reversal (OR 5.68; 95% CI 2.35-13.72; P < 0.001; I2 = 36%). Postoperative complications, such as thromboembolic events, surgical site infections, urinary tract infections, renal failure, and pneumonia, were not significantly different. CONCLUSION: DLI shows a lower postoperative mortality rate and higher ostomy reversal rate than TAC, suggesting it as a potential organ-preserving, minimally invasive alternative. Further high-quality studies and trials are needed to confirm these findings.

RESUMO

BACKGROUND: Recently, radio-frequency ablation has been used to modulate slow-wave activity in the porcine stomach. Gastric ablation is, however, still in its infancy compared to its history in the cardiac field, and electrophysiological studies have been restricted to temperature-controlled, non-irrigated ablation. Power-controlled, irrigated ablation may improve lesion formation at lower catheter-tip temperatures that produce the desired localized conduction block. METHODS AND RESULTS: Power-controlled, irrigated radio-frequency ablation was performed on the gastric serosal surface of female weaner pigs (n = 5) in vivo. Three combinations of power (10-15 W) and irrigation settings (2-5 mL min-1) were investigated. A total of 12 linear lesions were created (n = 4 for each combination). Slow waves were recorded before and after ablation using high-resolution electrical mapping. KEY RESULTS: Irrigation maintained catheter-tip temperature below 50°C. Ablation induced a complete conduction block in 8/12 cases (4/4 for 10 W at 2 mL min-1, 1/4 for 10 W at 5 mL min-1, 3/4 for 15 W at 5 mL min-1). Blocks were characterized by a decrease in signal amplitude at the lesion site, along with changes in slow-wave propagation patterns, where slow waves terminated at and/or rotated around the edge of the lesion. CONCLUSIONS AND INFERENCES: Power-controlled, irrigated ablation can successfully modulate gastric slow-wave activity at a reduced catheter-tip temperature compared to temperature-controlled, non-irrigated ablation. Reducing the irrigation rate is more effective than increasing power for blocking slow-wave activity. These benefits suggest that irrigated ablation is a suitable option for further translation into a clinical intervention for gastric electrophysiology disorders.

RESUMO

BACKGROUND: Chlorhexidine gluconate (CHG) (0.05%) has recently been suggested as both a dip for the hydrophilic surface and an irrigation solution in the setting of penile prosthesis (PP) surgery. AIM: The study sought to compare the antimicrobial efficacy of 0.05% CHG with vancomycin and gentamicin (VG) antibiotics as dip and/or irrigation solutions in the setting of a hydrophilic PP surface in vitro. METHODS: Sterile PPs with a hydrophilic coating were obtained. A series of experiments were performed to evaluate the efficacy of normal saline (NS), 0.05% CHG, or VG as dip and/or irrigation solutions to reduce methicillin-sensitive Staphylococcus aureus adhesion to PP surfaces. The 8-mm discs from PPs were incubated in 105 colony-forming units/mL of methicillin-sensitive S aureus for 48 hours, plated, and counted. Disc-diffusion tests were conducted by suspending 6-mm discs for 2 minutes in NS, 0.05% CHG, or VG, then placing them coated side down onto plates streaked with the following organisms: methicillin-sensitive S aureus, S epidermidis, Enterococcus, and Escherichia coli. After 24 hours of growth, zones of inhibition were measured. OUTCOMES: We found average bacterial counts (colony-forming units/mL) and zones of inhibition (mm) following a series of treatment protocols of PP discs. RESULTS: PP discs dipped in VG reduced bacterial adhesion to the implant surface >0.05% CHG (~5.5 log vs ~1.5 log; P < .01). Discs irrigated with either 0.05% CHG or NS removed all dip solution adsorbed to the hydrophilic surface, allowing bacterial growth. VG irrigation adsorbed to the hydrophilic surface even after 0.05% CHG or NS dips, reducing bacterial adherence (~3 log). Dipping and irrigating discs with VG was most effective in reducing adherent bacteria (~5.5 log) and was the only irrigation that showed antimicrobial activity. CLINICAL TRANSLATION: VG, when used both as a prophylactic dip and as an intraoperative irrigation solution for hydrophilic penile implant surfaces, has improved efficacy to 0.05% CHG and NS. STRENGTHS AND LIMITATIONS: This is the first study to compare the use of VG, 0.05% CHG, and NS as prophylactic dips and intraoperative irrigations for hydrophilic penile implant surfaces. Limitations include the use of in vitro studies, which serve as a proxy for in vivo practices and may not be entirely accurate nor translatable clinically. CONCLUSION: We demonstrated the superior efficacy of VG as a combined dip and irrigation solution for hydrophilic penile implant surfaces compared with 0.05% CHG.

RESUMO

BACKGROUND: 0.05% Chlorhexidine gluconate (CHG; Irrisept [IrriMax]) is a commercial wound irrigation solution approved by the Food and Drug Administration that has seen recent adoption in the field of prosthetic urology; however, no study has evaluated whether 0.05% CHG is compatible with the minocycline-rifampin-impregnated surface (InhibiZone) of the AMS 700 penile prosthesis (Boston Scientific). AIM: To evaluate whether 0.05% CHG alters the antibiotic efficacy of the minocycline-rifampin-impregnated penile prosthesis surface. METHODS: Discs (8 mm) were taken by a punch biopsy (Sklar) from sterile penile prosthesis reservoirs whose surfaces had been impregnated with rifampin and minocycline. Discs (n = 10) were suspended in 0.05% CHG, vancomycin and gentamicin, or normal saline for 2 minutes to simulate intraoperative irrigation. Discs were then rinsed in normal saline to remove any unbound solution and incubated with methicillin-sensitive Staphylococcus aureus for 48 hours. Adherent surface bacteria were suspended by shaking in a 0.3% Tween 20 solution, serially diluted, plated onto 3M PetriFilms, and counted. Kirby-Bauer disc diffusion assays were conducted to generalize findings across various organisms. OUTCOMES: Outcomes included (1) bacterial adherence to the implant surface measured as bacterial counts (in colony-forming units per milliliter) and (2) bacterial growth reduction measured as zones of inhibitions (in millimeters). RESULTS: Incubation of implant surfaces in 0.05% CHG did not alter recovered bacterial counts as compared with normal saline and vancomycin/gentamycin. Similarly, within a single bacterial species, 0.05% CHG and vancomycin/gentamycin did not alter zone-of-inhibition measurements in Kirby-Bauer disc diffusion studies. CLINICAL TRANSLATION: This study demonstrates in vitro that 0.05% CHG may be used directly on the minocycline-rifampin-impregnated surface without altering the antibiotic efficacy of the coating. STRENGTHS AND LIMITATIONS: Strengths include that this is the first study to evaluate if 0.05% CHG affected the minocycline-rifampin-impregnated surface. Limitations include the use of in vitro studies, which serve as a proxy for in vivo practices and may not be entirely accurate or translatable in a clinical setting. CONCLUSION: 0.05% CHG does not alter the antimicrobial activity of the minocycline-rifampin-impregnated surface as compared with vancomycin/gentamycin and normal saline in vitro; however, its efficacy in clinical practice remains to be evaluated.

RESUMO

BACKGROUND: This study evaluated the safety and efficiency of intraperitoneal irrigation chemotherapy with lobaplatin for the treatment of advanced gastric cancer (GC). METHODS: A total of 56 locally advanced GC patients (experimental group) who received intraoperative intraperitoneal irrigation chemotherapy in addition to undergoing radical D2 surgery were matched 1:1 based on 8 covariates to 56 patients without drug treatment (control group). Clinical data were collected and analyzed. RESULT: The two groups were well balanced in basic characteristics and had comparable clinical indices. All patients had similar time to first flatus (2.8 ± 0.3 vs. 2.9 ± 0.3 d, P = 0.076), time to first oral intake (3.5 ± 3.4 vs. 4.1 ± 4.6 d, P = 0.439), and duration of postoperative hospitalization (9.1 ± 3.2 vs. 9.6 ± 4.0 d, P = 0.446). There were no significant differences in postoperative complications including anastomotic and duodenal stump leakage, abdominal and anastomotic bleeding, seroperitoneum, and incision infection between the experimental and control groups (P > 0.05). The rates of chemotherapy-related side effects including allergic reaction, neurotoxicity, diarrhea, and nausea/vomiting were also similar between the two groups, and there were no abnormalities in leukocyte and platelet levels and liver and renal function during the first 5 days after surgery. CONCLUSION: Intraperitoneal irrigation chemotherapy with lobaplatin is safe for patients with advanced gastric cancer.

RESUMO

BACKGROUND: With the increasing number of joint replacement surgeries, periprosthetic joint infection (PJI) has become a significant concern in orthopedic practice, making research on PJI prevention paramount. Therefore, the study will aim to compare the effect of combined usage of povidone-iodine and topical vancomycin powder to the use of povidone-iodine alone on the PJI incidence rate in patients undergoing primary total hip (THA) and total knee arthroplasty (TKA). METHODS: The prospective randomized clinical trial will be conducted in two independent voivodeship hospitals with extensive experience in lower limb arthroplasties. The studied material will comprise 840 patients referred to hospitals for primary THA or TKA. The patients will be randomly allocated to two equal groups, receiving two different interventions during joint replacement. In group I, povidone-iodine irrigation and consecutively topical vancomycin powder will be used before wound closure. In group II, only povidone-iodine lavage irrigation will be used before wound closure. The primary outcome will be the incidence rate of PJI based on the number of patients with PJI occurrence within 90 days after arthroplasty. The occurrence will be determined using a combined approach, including reviewing hospital records for readmissions and follow-up phone interviews with patients. The infection will be diagnosed based on Musculoskeletal Infection Society criteria. The chi-square test will be used to compare the infection rates between the two studied groups. Risk and odds ratios for the between-groups comparison purposes will also be estimated. Medical cost analysis will also be performed. DISCUSSION: A randomized clinical trial comparing the effect of combined usage of povidone-iodine irrigation and vancomycin powder to the use of povidone-iodine irrigation alone in preventing PJIs after primary arthroplasty is crucial to advancing knowledge in orthopedic surgery, improving patient outcomes, and guiding evidence-based clinical practices.

RESUMO

PURPOSE: To explore the clinical effect of ultrasonic irrigation combined with chlorhexidine in root canal treatment of pulpitis. METHODS: A total of 120 patients with pulpitis treated with root canal therapy were randomly divided into a study group (n=60, 72 affected teeth) and a control group (n=60, 70 affected teeth). During root canal preparation, the study group was treated with chlorhexidine combined with ultrasonic irrigation, while the control group was treated with chlorhexidine conventional irrigation. The bacterial count and endotoxin content in the root canal before and after root canal preparation were compared between the two groups, as well as the endodontic inter-appointment pain (EIAP), lateral branch root canal filling rate, and degree of tooth pain after root canal treatment. The success rate of treatment was statistically analyzed after one-year follow-up. Statistical analysis was performed with SPSS 19.0 software package. RESULTS: After root canal preparation, the number of colonies in experimental group and control group was significantly decreased compared with that before root canal preparation(P<0.05), and the number of colonies in experimental group was significantly lower than that in control group(P<0.05). After root canal preparation, endotoxin levels in experimental group and control group were significantly lower than those before root canal preparation(P<0.05), and the level in experimental group was significantly lower than that in control group(P<0.05). The lateral branch root canal filling rate in the study group and the control group was 29.17% and 11.43%, respectively, with significant difference between the groups(P<0.05). The incidence of EIAP was 4.17% and 14.29%, respectively, with significant difference between the two groups(P<0.05). At 48 hours after surgery, the visual analogue score (VAS) of the study group and the control group was (2.74±0.61) and (3.29±0.68), respectively, which were significantly lower than at before surgery(P<0.05). There was a significant difference in VAS score between the two groups 48 hours after surgery(P<0.05). One week after surgery, the VAS score in the study group and the control group was (1.52±0.34) and (1.81±0.42), respectively, significantly lower than that before and 48 hours after surgery(P<0.05). There was a significant difference in VAS score between the two groups at one week after surgery (P<0.05). The successful rate of treatment in the control group was 84.62%, and 95.71% in the study group, with a significant difference between the two groups(P<0.05). CONCLUSIONS: The application of ultrasonic irrigation combined with chlorhexidine in the treatment of pulpitis root canals can help reduce the level of bacteria and endotoxin after root canal preparation, alleviate the degree of postoperative tooth pain, and improve the filling rate of lateral branch root canals, with superior curative effects.

RESUMO

PURPOSE: Intraocular irrigating solution is extensively applied in cataract surgery. This paper explored the difference and relationship between optical coherence tomography (OCT) and optical quality analysis system (OQAS) parameters induced by compound electrolyte intraocular irrigating solution (CEIIS) or Ringer lactate (RL) solution during uncomplicated cataract surgery. METHODS: Totally 200 senior cataract patients were randomly divided into the CEIIS and RL groups (N = 100 patients/group). The anterior chamber was irrigated by CEIIS or RL during phacoemulsification. Patients were subdivided into diabetes mellitus (DM)+ and DM- groups. The central macular thickness (CMT), hyper reflective foci (HF), modulation transfer function cutoff frequency (MTF cutoff), Strehl ratio (SR), objective scatter index (OSI), and OQAS values (OVs) at 100%, 20%, and 9% contrast levels were measured preoperatively and 1 day and 1 week after operation using spectral-domain optical coherence tomography and OQAS II, respectively. Best-corrected visual acuity (BCVA) was assessed using the Snellen scale, followed by statistical analysis of its logarithm of the minimal angle of resolution. RESULTS: There were no significant differences in clinical characteristics between the CEIIS and RL groups. Both groups exhibited notably increased postoperative CMT, MTF cutoff, SR, OV at 100%, 20%, and 9% contrast levels, and reduced OSI, indicating CEIIS and RL improved postoperative visual quality. CEIIS surpassed RL solution in improving postoperative visual quality, decelerating the increase of macular HF numbers and CMT in DM+ patients and postoperative BCVA. There was no difference between CEIIS and RL in long-term vision improvement. CONCLUSION: CEIIS surpasses RL in postoperative visual recovery and retards increases of macular HF numbers and CMT in senior DM+ cataract patients.

RESUMO

OBJECTIVE: To compare the osteoblastic activity and osteogenic potential of autogenous particle harvesting during implant surgery using low-speed drilling without irrigation and high-speed drilling with irrigation. MATERIALS AND METHODS: Thirty patients with bilateral missing teeth of 3.6 and 4.6 were randomized into two groups (Group 1: low-speed drilling without irrigation and Group 2: high-speed drilling with irrigation) and 60 single dental implants were placed. The temperature at the tip of each drill was recorded and the harvested bone was weighed; particle size and Ca and P levels were also analyzed. After osteoblast culture, cell viability, cell cycle assay, cell migration, vascular endothelial growth factor (VEGF) concentration, and mineralized nodule formation were assessed. RESULTS: Although the temperature of the drills was slightly higher in Group 1, no statistically significant differences were observed (p ≤ 0.05); however, the amount of harvested bone was higher (p < 0.001) and the size of the particles was higher (p = 0.019). In relation to osteoblastic activity and osteogenic potential, higher cell proliferation, higher number of cells in G2/M and S phases, higher cell migration capacity, higher VEGF concentration, and higher amount of mineralized nodule formation were observed in Group 1. CONCLUSIONS: Low-speed drilling without irrigation does not result in a significant increase in bone temperature compared to conventional drilling. However, a greater amount of bone is obtained; in addition, osteoblastic activity and osteogenic potential are higher with this technique, but further clinical studies are necessary.

RESUMO

BACKGROUND: The irrigation efficacy of a povidone-iodine solution to prevent surgical site infection is still controversial. We assessed the irrigation effect with a povidone-iodine solution on the incidence of surgical site infection after gastroenterological surgery. METHODS: This study is a single-center, prospective, randomized, blinded-end point superiority trial for surgical wound irrigation. Patients undergoing gastroenterological surgery were randomly assigned in a 1:1 replacement ratio using computer-generated randomization. Patients were grouped according to their surgical wound treatment into the control group using the normal sterile saline and the povidone-iodine group using 10% povidone-iodine solution after the NS solution. The main finding was 30-day surgical site infections assessed in the full analysis set. RESULTS: From November 2020 to December 2022, 697 of 894 patients were eligible for the study, among which 347 were in the povidone-iodine group and 350 in the control group. Thirty-day surgical site infections occurred in 100 (14%) patients-54 (16%) in the povidone-iodine group and 46 (13%) in the control group (odds ratio, 1.229; 95% CI, 0.800-1.889; P = .406). Superficial incisional surgical site infections occurred in 30 (9%) and 15 (4%) patients, respectively (odds ratio, 2.154; 95% CI, 1.134-4.090; P = .026). Only 3 patients (1%) in the control group developed adverse skin reactions. CONCLUSION: This study examined the irrigation efficacy of povidone-iodine for surgical site infection prevention compared to control in gastroenterological surgery. Povidone-iodine wound irrigation has shown no additional beneficial effect on the occurrence of surgical site infections.

RESUMO

BACKGROUND: The aim was to ascertain the impact of irrigation technique on human intrarenal pressure during retrograde intrarenal surgery. METHODS: A parallel randomized trial recruited patients across three hospital sites. Patients undergoing retrograde intrarenal surgery for renal stone treatment with an 11/13-Fr ureteral access sheath were allocated randomly to 100 mmHg pressurized-bag (PB) or manual hand-pump (HP) irrigation. The primary outcome was mean procedural intrarenal pressure. Secondary outcomes included maximum intrarenal pressure, variance, visualization, HP force of usage, procedure duration, stone clearance, and clinical outcomes. Live intrarenal pressure monitoring was performed using a COMETTMII pressure guidewire, deployed cystoscopically to the renal pelvis. The operating team was blinded to the intrarenal pressure. RESULTS: Thirty-eight patients were randomized between July and November 2023 (trial closure). The final analysis included 34 patients (PB 16; HP 18). Compared with PB irrigation, HP irrigation resulted in significantly higher mean intrarenal pressure (mean(s.d.) 62.29(27.45) versus 38.16(16.84) mmHg; 95% c.i. for difference in means (MD) 7.97 to 40.29 mmHg; P = 0.005) and maximum intrarenal pressure (192.71(106.23) versus 68.04(24.16) mmHg; 95% c.i. for MD 70.76 to 178.59 mmHg; P < 0.001), along with greater variance in intrarenal pressure (log transformed) (6.23(1.59) versus 4.60(1.30); 95% c.i. for MD 0.62 to 2.66; P = 0.001). Surgeon satisfaction with procedural vision reported on a scale of 10 was higher with PB compared with HP irrigation (mean(s.d.) 8.75(0.58) versus 6.28(1.27); 95% c.i. for MD 1.79 to 3.16; P < 0.001). Subjective HP usage force did not correlate significantly with transmitted intrarenal pressure (Pearson R = -0.15, P = 0.57). One patient (HP arm) developed urosepsis. CONCLUSION: Manual HP irrigation resulted in higher and more fluctuant intrarenal pressure trace (with inferior visual clarity) than 100-mmHg PB irrigation.

RESUMO

OBJECTIVE: This study aimed to evaluate the application of choledochoscopy combined with double-cannula lavage in the treatment of acute pancreatitis (AP) with encapsulated necrosis and analyzed related inflammatory indexes. METHODS: Thirty patients with AP with encapsulated necrosis were enrolled and treated with choledochoscopy and double-cannula lavage. Serum white blood cell (WBC), procalcitonin (PCT), C-reactive protein (CRP), interleukin 6 (IL-6), IL-8, tumor necrosis factor alpha (TNF-α), and related inflammatory indexes were detected before and after surgery. RESULTS: All of the participants who underwent the surgery recovered well and were discharged without serious complications; no deaths occurred. The serum WBC, PCT, and CRP of patients after surgery decreased compared with before the procedure, and the differences in WBC and CRP were statistically significant (P < 0.05); the difference in PCT was not statistically significant (P > 0.05). Postoperatively, IL-6, IL-8, and TNF-α levels were higher than before surgery, and the differences were statistically significant (P < 0.05). CONCLUSION: The surgical method presented herein effectively controlled and alleviated the infection of patients; it also did not increase the risk of infection and can thus be considered a safe and effective surgical method.

RESUMO

PURPOSE: To characterise the investigations, management and ultimate diagnosis of neonates with distal intestinal obstruction. METHODS: Retrospective review of term (> 37 weeks) neonates with admission diagnosis of distal intestinal obstruction over 10 years (2012-2022). Patient pathways were identified and associations between presentations, response to treatments and outcome investigated. RESULTS: A total of 124 neonates were identified and all included. Initial management was colonic irrigation in 108, contrast enema in 4, and laparotomy in 12. Of those responding to irrigations none underwent contrast enema. Ultimately, 22 neonates proceeded to laparotomy. Overall, 106 had a suction rectal biopsy and 41 had genetic testing for cystic fibrosis. Final diagnosis was Hirschsprung disease (HD) in 67, meconium ileus with cystic fibrosis (CF) in 9, meconium plug syndrome in 19 (including 3 with CF), intestinal atresia in 10 and no formal diagnosis in 17. Median length of neonatal unit stay was 11 days (7-19). CONCLUSIONS: Initial management of neonates with distal bowel obstruction should be colonic irrigation since this is therapeutic in the majority and significantly reduces the need for contrast enema. These infants should all have suction rectal biopsy to investigate for HD unless another diagnosis is evident. If a meconium plug is passed, testing for CF is recommended. Evaluation and therapy are multimodal and time consuming, placing burden on resources and families.

RESUMO

Ho: YAG laser lithotripsy is widely used for urinary stone treatment, but concerns persist regarding its thermal effects on renal tissues. This study aimed to monitor intrarenal temperature changes during kidney stone treatment using retrograde intrarenal surgery with Ho: YAG laser. Fifteen patients were enrolled. Various laser power settings (0.8 J/10 Hz, 1.2 J/12 Hz) and irrigation modes (10 cc/min, 15 cc/min, 20 cc/min, gravity irrigation, and manual pump irrigation) were used. A sterile thermal probe was attached to a flexible ureterorenoscope and delivered into the calyceal system via the ureteral access sheath. Temperature changes were recorded with a T-type thermal probe with ± 0.1 °C accuracy. Laser power significantly influenced mean temperature, with a 4.981 °C difference between 14 W and 8 W laser power (p < 0.001). The mean temperature was 2.075 °C higher with gravity irrigation and 2.828 °C lower with manual pump irrigation (p = 0.038 and p = 0.005, respectively). Body mass index, laser power, irrigation model, and operator duty cycle explained 49.5% of mean temperature variability (Adj. R2 = 0.495). Laser power and operator duty cycle positively impacted mean temperature, while body mass index and specific irrigation models affected it negatively. Laser power and irrigation rate are critical for intrarenal temperature during Ho: YAG laser lithotripsy. Optimal settings and irrigation strategies are vital for minimizing thermal injury risk. This study underscores the need for ongoing research to understand and mitigate thermal effects during laser lithotripsy.

RESUMO

BACKGROUND: Chronic subdural haematoma is a common surgically treated intracranial emergency. Burr-hole drainage surgery, to evacuate chronic subdural haematoma, involves three elements: creation of a burr hole for access, irrigation of the subdural space, and insertion of a subdural drain. Although the subdural drain has been established as beneficial, the therapeutic effect of subdural irrigation has not been addressed. METHODS: The FINISH trial was an investigator-initiated, pragmatic, multicentre, nationwide, randomised, controlled, parallel-group, non-inferiority trial in five neurosurgical units in Finland that enrolled adults aged 18 years or older with a chronic subdural haematoma requiring burr-hole drainage. Patients were randomly assigned (1:1) by computer-generated block randomisation with block sizes of four, six, or eight, stratified by site, to burr-hole drainage either with or without subdural irrigation. All patients and staff were masked to treatment assignment apart from the neurosurgeon and operating room staff. A burr hole was drilled at the site of maximum haematoma thickness in both groups, and the subdural space was either irrigated or not irrigated before inserting a subdural drain, which remained in place for 48 h. Reoperations, functional outcome, mortality, and adverse events were recorded for 6 months after surgery. The primary outcome was the reoperation rate within 6 months. The non-inferiority margin was set at 7·5%. Key secondary outcomes that were also required to conclude non-inferiority were the proportion of participants with unfavourable functional outcomes (ie, modified Rankin Scale score of 4-6, where 0 indicates no symptoms and 6 indicates death) and mortality rate at 6 months. The primary and key secondary analyses were done in both the intention-to-treat and per-protocol populations. The trial was registered with ClinicalTrials.gov (NCT04203550) and is completed. FINDINGS: From Jan 1, 2020, to Aug 17, 2022, we assessed 1644 patients for eligibility and 589 (36%) patients were randomly assigned to a treatment group and treated (294 assigned to drainage with irrigation and 295 assigned to drainage without irrigation; 165 [28%] women and 424 [72%] men). The 6-month follow-up period extended until Feb 14, 2023. In the intention-to-treat analysis, 54 (18·3%) of 295 participants required reoperation in the group assigned to receive no irrigation versus 37 (12·6%) of 294 in the group assigned to receive irrigation (difference of 6·0 percentage points, 95% CI 0·2-11·7; p=0·30; adjusted for study site). There were no significant between-group differences in the proportion of people with modified Rankin Scale score of 4-6 (37 [13·1%] of 283 in the no-irrigation group vs 36 [12·6%] of 285 in the irrigation group; p=0·89) or mortality rate (18 [6·1%] of 295 in the no-irrigation group vs 21 [7·1%] of 294 in the irrigation group; p=0·58). The findings of the primary intention-to-treat analysis were not materially altered in the per-protocol analysis. There were no significant between-group differences in the number of adverse events, and the most frequent severe adverse events were systemic infections (26 [8·8%] of 295 participants who did not receive irrigation vs 22 [7·5%] of 294 participants who received irrigation), intracranial haemorrhage (13 [4·4%] vs seven [2·4%]), and epileptic seizures (five [1·7%] vs nine [3·1%]). INTERPRETATION: We could not conclude non-inferiority of burr-hole drainage without irrigation. The reoperation rate was 6·0 percentage points higher after burr-hole drainage without subdural irrigation than with subdural irrigation. Considering that there were no differences in functional outcome or mortality between the groups, the trial favours the use of subdural irrigation.
