Comparison of efficacy of tranexamic acid irrigation versus intravenous injection for preventing blood loss in percutaneous nephrolithotomy

Purpose: Bleeding is the most dreadful and distressing complication of percutaneous nephrolithotomy, which can cause significant morbidity. Intravenous use of tranexamic acid to reduce bleeding complication is widely established. Our aim is to compare the result between the two groups using tranexamic acid intravenous and in irrigation solution. Materials and methods: A total of 160 patients were enrolled in this study. Patients were randomly allocated to two groups. Group 1 received 0.1% tranexamic acid solution (1000 mg in 1 L of irrigation solution (normal saline)). Group 2 received 1 g tranexamic acid intravenously in intraoperative period. Results: The mean estimated fall in haematocrit, mean estimated total blood loss and mean operative time in tranexamic acid irrigation group is significantly less compared to intravenous tranexamic acid group. No significant difference was found with regards to stone clearance. Conclusion: We found that tranexamic acid irrigation was safe and associated with reduced blood loss as compared to intravenous tranexamic acid.

Efficacy of Acetic Acid Irrigation in Management of Chronic Suppurative Otitis Media “A Prospective Study

Background: Prior to surgical management of chronic suppurative otitis media (CSOM) for the dry ear medical management is necessary. CSOM is a biofilm disease and due to this has antibiotic resistance. The pillar of its treatment included aural cleaning according to standard protocols, application of topical germ free antiseptic and use of antimicrobials. Acetic acid due to its ability in reducing the pH may be effective in reducing the growth of microorganisms. Objective: The aim of the study was to compare the efficacy of irrigation with acetic acid versus systemic antibiotics in CSOM patients. Materials & Methods: A total of 134 patients, who came to the ENT department of Sheikh Zayed Hospital, Lahore between 1st April 2020 to 30th September 2020, who had CSOM, of age 15 to 55 years and both genders were included in the study. The patients were divided randomly into two groups. Group A patients received aural toilets and irrigation with acetic acid and Group B received 500 mg of ciprofloxacin twice a day for 2 weeks. Results: The mean age (in years) of the patients in Group A was 37.45±7.32 and in Group B, it was 37.96±7.57. The efficacy of irrigation with acetic acid versus systemic antibiotics was 89.55% and 68.66% respectively and this difference between the two groups was found to be statistically significant (p=0.003). Conclusion: Irrigation with acetic acid was better than systemic antibiotics in managing patients with CSOM. Key words: Acetic acid, CSOM, Middle ear

Role of 1.5% acetic acid irrigation and medical management in chronic persistent suppurative otitis media

<p><strong>Background</strong>: Chronic ear discharge in chronic suppurative otitis media (CSOM) persisting for more than two weeks has become difficult to treat for ENT specialists due to resistance to the available antibiotics and patient's affordability for its cost. Also, biofilms have been responsible for the disease and cause tympanic membrane perforation and deafness. The use of 1.5% acetic acid irrigation acts as an antiseptic, and altering the middle ear's pH to treat otorrhea in CSOM needs to be studied. Aim of the study to assess results of 1.5% acetic acid irrigation and topical and systemic antibiotic in CSOM and to consider the most appropriate medical management</p><p><strong>Methods</strong>: A total of 100 patients of CSOM was divided equally into two groups. Group 1 patients were treated with 1.5% acetic acid irrigation every other day, and group 2 was treated with topical and systemic antibiotics three drops’ times daily. Follow up of both groups every week up to symptomatic relief.</p><p><strong>Results</strong>: Otorrhoea resolution in the group treated with acetic acid was 88%, and healing of perforation was noted in 28 %, while the failure rate of 12%.</p><p><strong>Conclusions</strong>: Medical management of persistent CSOM with tubotympanic type by frequent aural cleaning, 1.5% acetic acid irrigation can be the more desirable choice than the topical and oral antibiotics. It is safe without any side effects and economical. Alteration of ear canal PH is one of the main factors for healing, in addition to mechanical disruption of biofilm and removal of deep-seated debris.</p><p><strong> </strong></p>

A case report of a unique aorto-bifemoral graft infection and its treatment

In this study, we report a unique case of aorto-bifemoral graft infection, which developed in a 47-year-old male patient after endovascular aortic aneurysmal repair (EVAR) and extra anatomic axillo-femoral bypass. The patient had previously been treated by EVAR for an infrarenal abdominal aortic aneurysm. Earlier, the EVAR was blocked by a thrombosis and treated with an extra-anatomic axillo femoral bypass, which then became occluded. The patient was then treated with an aorto-bifemoral bypass using a Dacron Y graft. A few months later, he was referred to our cardiovascular center with high body temperature, weight loss, inability to stand and walk, and very serious sepsis. A computed abdominal tomography scan revealed that a part of the graft proximal to the bifurcation had totally eroded into the proximal jejunum. We treated this patient with multiple surgeries, antibiotic administrations and hypochlorous acid irrigation without graft excision, which carries a high morbidity and mortality risks.

Ascorbic acid irrigation during debridement decreased the colony count of Staphylococcus aureus and interleukin-6 blood count in grade ii open fracture of long bones

Background: Infection in open fractures is still a problem that cannot be fully managed. Various types of studies have been conducted to find an effective and efficient solution to wash open fracture wounds. This study compared the effectiveness of ascorbic acid irrigation in reduction of Staphylococcus aureus colony and interleukin-6 (IL-6) serum level as systemic inflammation marker in debridement procedure of grade II Gustilo-Anderson open fracture of long bones.Methods: This study was an experimental study with pre-post-test control group design. This study included 24 subjects aged 15-75 years old with Gustillo-Anderson type II open fractures which were divided into two groups. The treatment group had additional irrigation by using 10 mg/ml ascorbic acid solution during debridement, whereas the control group had debridement only without irrigation with ascorbic acid. The culture and colony count of Staphylococcus aureus and IL-6 serum level was obtained and measured before and after the treatment in both groups. Statistical analysis (Wilcoxon test) was performed to compare the difference of the two parameters (Δ colony count and Δ IL-6) before and after the treatment.Results: There were no significant difference in Δ colony count of Staphylococcus aureus (p=0.308) and ΔIL-6 serum level (p=0.239) between the control group and treatment group.Conclusions: Ascorbic acid irrigation was not proved to decrease the colony count of Staphylococcus aureus and IL-6 serum level in grade II open fracture of long bones.

Therapeutic effect of ethylenediaminetetraacetic acid irrigation solution against wound infection with drug-resistant bacteria in a rat model: an animal study

Objectives Irrigation is the cornerstone of treating skeletal infection by eliminating pathogens in wounds. A previous study shows that irrigation with normal saline (0.9%) and ethylenediaminetetraacetic acid (EDTA) could improve the removal of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) compared with normal saline (NS) alone. However, it is still unclear whether EDTA solution is effective against infection with drug-resistant bacteria. Methods We established three wound infection models (skin defect, bone-exposed, implant-exposed) by inoculating the wounds with a variety of representative drug-resistant bacteria including methicillin-resistant S. aureus (MRSA), extended spectrum beta-lactamase-producing E. coli (ESBL-EC), multidrug-resistant Pseudomonas aeruginosa (MRPA), vancomycin-resistant Enterococcus (VRE), multidrug-resistant Acinetobacter baumannii (MRAB), multidrug-resistant Enterobacter (MRE), and multidrug-resistant Proteus mirabilis (MRPM). Irrigation and debridement were repeated until the wound culture became negative. The operating times required to eliminate pathogens in wounds were compared through survival analysis. Results Compared with other groups (NS, castile soap, benzalkonium chloride, and bacitracin), the EDTA group required fewer debridement and irrigation operations to achieve pathogen eradication in all three models of wound infection. Conclusion Irrigation with EDTA solution was more effective than the other irrigation fluids used in the treatment of wound infections caused by drug-resistant pathogens. Cite this article: Z.
