ABSTRACT
【Objective】 To explore the causes of hypothermia in patients undergoing transurethral thulium laser prostatectomy. 【Methods】 A total of 170 patients who underwent transurethral thulium laser prostatectomy in our hospital during Sep.2020 and May 2021 were prospectively enrolled in the study. The patients were divided into normal body temperature group (n=143) and hypothermia group (n=27), based on whether perioperative hypothermia happened. The clinical data were analyzed to evaluate the risk factors of hypothermia. 【Results】 Univariate analysis showed that there were statistical differences in anesthesia time, operation time, prostate size and total amount of perfusion fluid between the two groups (P<0.05). Logistic analysis showed that the size of prostate was the independent risk factor of perioperative hypothermia (P<0.05). Patients were further divided according to prostate size. For patients with prostate < 80 g, the size of prostate was the independent risk factor of perioperative hypothermia (P<0.05), while for patients with prostate ≥ 80 g, the amount of perfusion fluid was the independent risk factor (P<0.05). 【Conclusion】 Perioperative hypothermia in patients undergoing transurethral thulium laser prostatectomy is related to the anesthesia time, operation time, prostate size and total amount of perfusion fluid. It is necessary to evaluate the risk factors before operation and take effective thermal insulation measures.
ABSTRACT
Objective To investigate and evaluate the effects and safety of the operationabsorption of irrigation fluid occurs during 1470 nm diode laser vaporization of the prostate by ethano. Methods We retrospectively analyzed the clinical data about 32 cases of BPH treated by 1470 nm diode laser vaporization from May 2016 to December 2016 intraoperative use of isotonic saline contains 1.0％ ethanol as perfusion fluid, monitor the patients' breath ethanol concentration, calculation of perfusion fluid absorption. Results All the operations were successfully completed, the average operation time was (57.6 ± 32.9) min, the average perfusion fluid volume was (21.5 ± 9.9) L, only 5 cases detected perfusion fluid absorption, the average absorptive amount was (156.8 ± 111.7) ml. During operation, all the patients with stable breathing, circulation, no alcohol poisoning symptoms, no bleeding, capsular perforation, cardiorespiratory failure occurred. All the 32 cases patients were followed up for 3 months, which revealed a significant improvement in dysuresia, no severe complications such as urethrostenosis, urinary incontinence, secondary hemorrhage were noted. Conclusion Fluid absorption little occurs during 1470 nm diode laser vaporization, it is safe and effective in treatment of benign prostatic hyperplasia.
ABSTRACT
Objective To analyze the distribution of microorganisms in kidney perfusion fluid and perirenal drainage of the renal allografts,and provide evidence to guide clinical practice.Methods The clinical data from the kidney donors and the recipients,the microbiologic culture results of kidney perfusion fluid and perirenal drainage were retrospectively analyzed.Results Ninety-one kidney perfusion fluid samples and 91 perirenal drainage samples were collected from 61 individual renal allografts,and 48 renal allografts were paired.Fourteen (15.4％,14/91) cultured kidney perfusion fluid samples were positive,17 strains were confirmed including 13 strains of bacteria and 4 strains of fungal,and 9 (69.2％,9/13) of bacterial strains were multidrug-resistance with 7 strains resistant to carbapenems,but there was no significant heterogeneity in the outcome of recipients with positive or negative culture results of kidney perfusion fluid samples.Eight (8.8％,8/91) perirenal drainage samples from different recipients were positive,5 of 8 bacterial strains were multidrug-resistance and 3 of them were resistant to carbapenems including meropenem or imipenern.There was no significant correlation between the length of donors' hospital stay and the culture results (P＞0.05),and there was also no significant correlation between the length of recipients' hospital stay after transplantation and the culture results (P＞0.05).Conclusion The kidney with positive perfusion fluid microbiologic culture can be transplanted safely using the prophylaxis or preemptive anti-infection therapy.
ABSTRACT
To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study. ●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo. ●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P ●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.
