AbstractBackground: Multi-organ failure characterized by acute kidney injury, liver dysfunction, and respiratory failure is a complex condition associated with high mortality, for which multiple individual support devices may be simultaneously required. This review aims to appraise the current evidence for the ADVanced Organ Support (ADVOS) system, a novel device integrating liver, lung, and kidney support with blood detoxification. Methods: We performed a literature review of the PubMed database to identify human and animal studies evaluating the ADVOS system. Results: In porcine models of acute liver injury and small clinical studies in humans, ADVOS significantly enhanced the elimination of water-soluble and protein-bound toxins and metabolites, including creatinine, ammonia, blood urea nitrogen, and lactate. Cardiovascular parameters (mean arterial pressure, cerebral perfusion pressure, and cardiac index) and renal function were improved. ADVOS clears carbon dioxide (CO2 ) effectively with rapid correction of pH abnormalities, achieving normalization of CO2 , and bicarbonate levels. In patients with COVID-19 infection, ADVOS enables rapid correction of acid-base disturbance and respiratory acidosis. ADVOS therapy reduces mortality in multi-organ failure and has been shown to be safe with minimal adverse events. Conclusions: From the small observational studies analyzed, ADVOS demonstrates excellent detoxification of water-soluble and protein-bound substances. In particular, ADVOS permits the correction of metabolic and respiratory acidosis through the fluid-based direct removal of acid and CO2 . ADVOS is associated with significant improvements in hemodynamic and biochemical parameters, a trend toward improved survival in multi-organ failure, and is well-tolerated. Larger randomized trials are now necessary to further validate these encouraging results.

Antibiotic Prescription, Organisms and its Resistance Pattern in Patients Admitted to Respiratory ICU with Respiratory Infection in Mysuru.Ambalkar, Shrikant (2018-04)Aim of Study: Respiratory infections account for significant morbidity, mortality and expenses to patients getting admitted to ICU. Antibiotic resistance is a major worldwide concern in ICU, including India. It is important to know the antibiotic prescribing pattern in ICU, organisms and its resistance pattern as there is sparse data on Indian ICUs. Materials and Methods: We conducted a prospective study from August 2015 to February 2016. All patients getting admitted to RICU with respiratory infection who were treated with antibiotics were included into study. Demographic details, comorbidities, Clinco-pathological score (CPI) on day1 and 2 of admission, duration of ICU admission, number of antibiotics used, antibiotic prescription, antimicrobial resistance pattern of patients were collected using APRISE questionnaire. Results: During study period 352 patients were screened and 303 patients were included into study. Mean age was 56.05±16.37 and 190 (62.70%) were men. Most common diagnosis was Pneumonia (66%). Piperacillin-tazobactam was most common empirical antibiotic used. We found 60% resistance to piperacillin-tazobactam. Acinetobacter baumanii was the most common organism isolated (29.2%) and was highly resistant to Carbapenem (60%). Klebsiella pneumoniae was resistant to Amikacin (45%), piperacillin (55%) and Ceftazidime (50%). Conclusion: Piperacillin-tazobactam was the most common antibiotic prescribed to patients with respiratory infection admitted to ICU. More than half of patients (60%) had resistance to the empirical antibiotic used in our ICU, highlighting the need for antibiogram for each ICU. Thirty six percent of patient had prior antibiotic use and had mainly gram negative organisms with high resistance to commonly used antibiotics.
The incidence and causative organisms of infection in elective shoulder surgery.Bidwai, Amit S. (2018-07)Background Deep infection remains a serious complication of orthopaedic surgery. Knowledge of infection rates and causative organisms is important to guide infection control measures. The aim of the present study was to determine infection rates and causative organisms in elective shoulder surgery. Methods Cases complicated by infection were identified and prospectively recorded over a 2-year period. All patients undergoing elective shoulder surgery in the concurrent period at a single Specialist Upper Limb Unit in the UK were identified from the hospital electronic database. Results In total, 1574 elective shoulder cases were performed: 1359 arthroscopic (540 with implant insertion) and 215 open (197 with implant insertion). The overall infection rate in open surgery of 2.5% was significantly higher than arthroscopic implant cases at 0.7% (p < 0.005). The overall infection rate in implant arthroscopic surgery was significantly higher at 0.7% compared to 0% in non-implant related surgery. (p < 0.05) Conclusions Patients undergoing open shoulder surgery have a significantly higher risk of infection compared to arthroscopic shoulder surgery. Arthroscopic surgery with implant insertion has a statistically significantly higher risk of developing deep infection compared to procedures with no implant insertion. We recommend prophylactic antibiotics in open shoulder surgery and arthroscopic shoulder surgery with implant insertion.
