COMBINED USE OF VIDEOLARYNGOSCOPE AND BONFILS INTUBATION ENDOSCOPE AS RESCUE OPTION FOR DIFFICULT AIRWAY MANAGEMENT: A CASE REPORT.

Difficult airway management poses a great challenge for clinicians, especially if it is unanticipated. Numerous guidelines and a wide array of devices constitute the anesthesiologist's armamentarium for managing the airway. When the use of individual devices fails, the use of combination techniques is advised. We present a case of difficult intubation in a 50-year-old male patient scheduled for aortic valve replacement. He had no prior history of difficult airway management, and no abnormalities were detected on preoperative airway assessment. Body mass index was 29 kg/m2. After the separate use of direct laryngoscopy, videolaryngoscopy and a BONFILS intubation endoscope (BIE) had failed, we resorted to a combination technique, combining videolaryngoscopy and BIE. While the videolaryngoscope provided the space needed for BIE and visual guidance through copious secretions, the BIE served as a stylet for endotracheal tube guidance, leading to successful intubation. Since the technique requires costly equipment, experience in handling it and at least two operators, it is more appropriate as a rescue measure than an elective procedure. Given the potentially disastrous outcomes of failed intubation, mastering advanced airway management techniques remains of vital importance, and the combination technique is one of them.

Multidrug-Resistant Bacteria in a COVID-19 Hospital in Zagreb.

During November to December 2020, a high rate of COVID-19-associated pneumonia with bacterial superinfections due to multidrug-resistant (MDR) pathogens was recorded in a COVID-19 hospital in Zagreb. This study analyzed the causative agents of bacterial superinfections among patients with serious forms of COVID-19. In total, 118 patients were hospitalized in the intensive care unit (ICU) of the COVID-19 hospital. Forty-six out of 118 patients (39%) developed serious bacterial infection (VAP or BSI or both) during their stay in ICU. The total mortality rate was 83/118 (70%). The mortality rate due to bacterial infection or a combination of ARDS with bacterial superinfection was 33% (40/118). Six patients had MDR organisms and 34 had XDR (extensively drug-resistant). The dominant species was Acinetobacter baumannii with all isolates (34) being carbapenem-resistant (CRAB) and positive for carbapenem-hydrolyzing oxacillinases (CHDL). One Escherichia coli causing pneumonia harboured the blaCTX-M-15 gene. It appears that the dominant resistance determinants of causative agents depend on the local epidemiology in the particular COVID center. Acinetobacter baumannii seems to easily spread in overcrowded ICUs. Croatia belongs to the 15 countries in the world with the highest mortality rate among COVID-19 patients, which could be in part attributable to the high prevalence of bacterial infections in local ICUs.
