Effectiveness of Peripheral Nerve Block in Terms of Search for a Standardized Treatment Protocol in Diabetic Foot Patients Using Anticoagulants: A Double-Center Study.

BACKGROUND: Lower-extremity amputation for a diabetic foot is mainly performed under general or central neuraxial anesthesia. Ultrasound-guided peripheral nerve block (PNB) can be a good alternative, especially for patients who require continuous anticoagulation treatment and patients with additional comorbidities. We evaluated bleeding due to PNB application in patients with diabetic foot receiving antiplatelet or anticoagulant therapy. Perioperative morbidity and mortality and the need for intensive care hospitalization were analyzed. METHODS: This study included 105 patients with diabetic foot or debridement who underwent distal foot amputation or debridement between February and October 2020. Popliteal nerve block (17 mL of 5% bupivacaine and 3 mL of saline) and saphenous nerve block (5 mL of 2% lidocaine) were applied to the patients. Postoperative pain scores (at 4, 8, 12, and 24 hours) and complications due to PNB were evaluated. Intensive care admission and 1-month mortality were recorded. RESULTS: The most common diseases accompanying diabetes were hypertension and peripheral artery disease. No complications due to PNB were observed. Mean ± SD postoperative first analgesic need was determined to be 14.1 ± 4.1 hours. Except for one patient, this group was followed up without the need for postoperative intensive care. In 16 patients, bleeding occurred as leakage from the surgical area, and it was stopped with repeated pressure dressing. Mean ± SD patient satisfaction score was 8.36 ± 1.59. Perioperative mortality was not observed. CONCLUSIONS: Ultrasound-guided PNB can be an effective and safe anesthetic technique for diabetic patients undergoing distal foot amputation, especially those receiving antiplatelet or anticoagulant therapy and considered high risk.

[Artificial intelligence-powered ultrasound guided regional nerve block in three patients: Case report]. / Yapay zeka destekli ultrasonografi rehberliginde 3 hastada rejyonel sinir bloku: Olgu sunumu.

The use of ultrasound in regional anesthesia plays an important role in determining the variable anatomical structures and their localization. In these days, developments in ultrasonography devices and probes, hardware, and software technologies such as real-time needle tip tracking are increasing rapidly. Artificial intelligence-powered ultrasonography is one of them. In this case report, we aimed to present three cases where regional block was applied using artificial intelligence-powered (Nerveblox) ultrasound. Infraclavicular nerve block to two of our patients and pectoral nerve block to the third one were applied successfully once at a time. None of the patients developed vascular puncture or local anesthetic toxicity. The use of artificial intelligence support in peripheral nerve blocks may reduce the number of attempts and duration of interventions.

Comparison of demographic and clinical characteristics between pandemic and pre-pandemic period in non-COVID intensive care units: a retrospective study.

BACKGROUND: A major problem of the coronavirus pandemic is the increase of patients requiring intensive care unit (ICU) sup-port in an extremely limited period of time. As a result, most countries have prioritized coronavirus disease 2019 (COVID-19) care in ICUs and take new arrangements to increase hospital capacity in emergency department and ICUs. This study aimed to evaluate the changes in the number, clinical and demographic characteristics of patients hospitalized in non-COVID ICUs during the COVID-19 pandemic period compared to the previous year (pre-pandemic period), and to reveal the effects of the pandemic. METHODS: Hospitalized patients in non-COVID ICUs of our hospital between 11 March 2019 and 11 March 2021 were included in the study. The patients were divided into two groups according to date of the start of the COVID period. Patient data were scanned and recorded retrospectively from hospital information system and ICU assessment forms. Information regarding demographics (age and gender), comorbidities, COVID 19 polymerase chain reaction result, place of ICU admission, the diagnoses of patients admitted to ICU, length of ICU stay, Glasgow coma scale and mortality rates, and the Acute Physiology and Chronic Health Evaluation II score were collected. RESULTS: A total of 2292 patients were analyzed, including 1011 patients (413 women and 598 men) in the pre-pandemic period (Group 1) and 1281 patients (572 women and 709 men) in the pandemic period (Group 2). When the diagnoses of patients admitted to ICU were compared between the groups, there was a statistically significant difference between post-operation, return of spon-taneous circulation, intoxication, multitrauma, and other reasons. In the pandemic period, the patients had a statistically significant longer length of ICU stay. CONCLUSION: Changes were observed in the clinical and demographic characteristics of patients hospitalized in non-COVID-19 ICUs. We observed that the length of ICU stay of the patients increased during the pandemic period. Due to this situation, we think that intensive care and other inpatient services should be managed more effectively during the pandemic.
