Statement of the Expert Discussion Panel of the 1st Expert Conference on Point­of­Care ultrasound.

The document summarizes the statement of the expert discussion panel of the 1st Point- of-Care Ultrasonography, which took place on 14 November 2022 in Prague and which led to the foundation of the Czech Multidisciplinary Task Force Group for standards,education and research in Point-of-Care ultrasound (Czech POCUS group).

[Continuing peripheral nerve blocks - benefit for orthopedic patients with diabetes mellitus?]. / Pokracující periferní nervové blokády - prínos pro ortopedické pacienty s diabetes mellitus?

There is increasing incidence of diabetes mellitus in population of developed countries. And there is also, together with this fact, an increasing frequency of surgical not only orthopedic procedures for diabetic complications or for other reasons. However, thanks to modern sophisticated perioperative approaches, diabetes itself is no longer main risk factor for worsening of perioperative morbidity and mortality. The organ complications of diabetes still remain the crucial for patients outcome. The individual approach to each patient is important when we are plann-ing anesthesiological perioperative strategy. Assessment of long term diabetes compensation before elective surgical procedures, assessment and optimization of organ functions with searching for possible secondary complications of diabetes is also crucial. Generally, it is necessary to maintain compensation of diabetes through the whole perioperative period, avoid episodes of hypotension and tissue hypoperfusion and all anesthesiological interventions have to be targeted to rapid recovery (chronic medication, oral feeding and early rehabilitation). Technics of regional anesthesia and peripheral nerve blocks particularly, may be very useful for the objective especially for ortho-pedic patients.Key words: anesthesia - diabetes mellitus - perioperative period - peripheral nerve blocks.

Laparoscopic diagnostics of acute bowel ischemia using ultraviolet light and fluorescein dye: an experimental study.

PURPOSE: The aim of the study was to show the diagnostic potential of laparoscopy using fluorescein dye and ultraviolet light in acute bowel ischemia. MATERIALS AND METHODS: The study involved 12 domestic pigs. Under general anesthesia, the peripheral branch of the superior mesenteric artery was embolized using polyvinyl-alcohol microparticles. Two hours after the embolization, optical filters were placed into the laparoscopic set to produce ultraviolet light. Fluorescein dye was given intravenously, and the bowel was inspected. Clips were placed on the border of the ischemia that was visualized with fluorescein. Resection of the ischemic part of the bowel and anastomosis of the viable parts were carried out using laparoscopic linear cutting staplers. After 24 hours, a laparoscopic second-look procedure was carried out to verify the viability of the anastomosis. RESULTS: The method was in all cases able to recognize intestinal ischemia and reliably differentiate ischemic bowel segments from viable bowel. Microscopic analysis of the ischemic specimens showed beginning ischemic changes of the bowel tissues. CONCLUSIONS: The method should be considered a valuable diagnostic procedure both for diagnostics of early stage of acute bowel ischemia and for second-look procedures.
