Post Discharge After Surgery Virtual Care With Remote Automated Monitoring Technology (PVC-RAM) Trial

The Post discharge after surgery Virtual Care with Remote Automated Monitoring technology (PVC-RAM) Trial is a multicentre, parallel group, superiority, randomized controlled trial to determine the effect of virtual care with remote automated monitoring (RAM) technology compared to standard care on days alive at home during the 30-day follow-up after randomization, in adults who have undergone semi-urgent (e.g., oncology), urgent (e.g., hip fracture), or emergency (e.g., ruptured abdominal aortic aneurysm) surgery. It will also determine, during the first 30 days, the effect of virtual care with RAM technology on several secondary outcomes, including: 1. hospital re-admission; 2. emergency department visit; 3. urgent-care centre visit; 4. acute-hospital care (i.e., a composite of hospital re-admission and emergency department or urgent-care centre visit) 5. brief acute-hospital care (i.e., acute-hospital care that lasts <24 hours); 6. all-cause hospital days; 7. medication error detection; 8. medication error correction; and 9. death. An additional secondary objective is to determine the effect of virtual care with RAM technology on pain at 7, 15, and 30 days and 6 months after randomization.

Intraoperative Phlebotomies and Bleeding in Liver Transplantation

Liver transplantation are surgeries associated with important bleeding and often require perioperative red blood cell (RBC) transfusions. Overall, between 20 and 85 % of liver transplant recipients receive at least one RBC transfusion during their surgery. Such transfusions are consistently associated with higher morbidity and mortality, although this causal association is still under debate in many surgical populations. Despite the lack of clear causative association between perioperative transfusions and worse outcomes, minimizing bleeding and transfusions is believed to improve postoperative outcomes. Many perioperative variables are associated with higher blood loss and need for perioperative transfusions: liver disease severity, preoperative anemia and coagulopathy, higher cardiac filling pressures and higher fluid administration, among others. However, few perioperative interventions have been shown to reduce bleeding and transfusion requirements in this population. Among them, the use of intraoperative phlebotomies to reduce portal and hepatic venous pressure during the dissection phase is a promising one, also described in liver resection surgery. To further investigate the effects of intraoperative phlebotomies on intraoperative bleeding, perioperative transfusions and mortality, the Principal Investigator will conduct a retrospective cohort study with a propensity score based causal analysis.

Ketamine Infusion vs Dexmedetomidine Infusion in Obese Patients Undergoing Bariatric Surgery

The surgeries that involve treatment of morbid obesity, i.e. bypass procedure and sleeve gastrectomy, are collectively covered under the term 'bariatric surgery'. The frequency of bariatric surgery has been increasing worldwide for patients with medically complicated obesity who have difficulty losing weight by other methods The growth of bariatric surgery is accompanied with development of anesthetic techniques to maintain patient safety and improve outcome. Treatment with narcotics in obese patients has dual effect. Increased use of narcotics are associated with multiple complications including Postoperative Nausea and Vomiting (PONV) , respiratory depression and elevated risk of Obstructive Sleep Apnea (OSA) complications . On the other hand, the reduction in opioid use may result in acute post-operative pain that may limit post-surgery rehabilitation. Therefore, we need to minimize opioid use and employ some other drugs which, besides having analgesia, has an opioid-sparing effect also. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has analgesic properties in sub-anesthetic doses. When used in low dose (0.3 to 0.5 mg/kg) by ideal body weight, it is an analgesic, anti-hyperalgesic, and prevents development of opioid tolerance. Dexmedetomidine is selective ?2-Adrenoceptor agonist that has been used as an adjuvant to anesthetic agents in perioperative period for several adventitious profile as well as tolerated side effects . While dexmedetomidine is emerging as a beneficial adjunct to the analgesic regimen in the perioperative period, its utilization is not routinely widespread .

Risk of Air Contamination During Visceral Surgery in COVID19 Patients

Sars-Cov2 has been found in the digestive tract, as well as the respiratory tract. Protection of health care workers during surgery has been increased and some guidelines advocate for abandoning laparoscopy in COVID19 patients for fear of contamination, evenghtough this does not benefit the patient. However, Sars-Cov2 contamination risk during visceral surgery remains unknown. Inadequate protection is unnecessary costful and can be inefficient if too binding. Our hypotheses are that 1) Sars-Cov 2 can travel through droplet and air during visceral surgery. 2) Laparoscopy, because of the pneumoperitoneum and its leaks, warrant more air contamination whereas laparotomy warrant more droplet contamination, which would justified increased protection.

Management of Antiplatelet Regimen During Surgical Procedures

There are key differences today in clinical practice regarding perioperative management of post-PCI patients on DAPT undergoing NCS. Moreover, there are significant differences between bridging agents, and improved safety of current-generation DES. Given the significant limitations of current studies a well-designed registry to study current U.S. practice patterns and the bleeding or ischemic risks associated with the various perioperative DAPT management strategies including bridging and no bridging will significantly add to the understanding of the current problem and associated risks of patients. These data could form the basis for conducting future randomized clinical trials (RCTs) in this area. NCS in post-PCI patients on chronic DAPT presents a complex interaction of both ischemic and bleeding risks. The MARS registry will study the area of perioperative antiplatelet therapy management through a multicenter observational national registry designed to collect pre-operative, intra-operative and post-operative clinical strategies, therapeutic interventions and outcomes data. This proposal outlines the role of a highly experienced clinical trial team to conduct a multicenter prospective registry. This question is highly relevant to a diverse group of medical providers and millions of patients in the US and around the world; this will be the first such U.S. registry to address this critically important public health issue. Study objectives: i. To collect data on contemporary clinical practice in the U.S. on managing post percutaneous coronary intervention (PCI) DAPT in patients scheduled to undergo NCS and CS. ii. To assess ischemic and bleeding endpoints in this group of patients during the study period. iii. To generate initial data to plan for future large-scale randomized clinical trials on perioperative management of DAPT.

Role of Cerebral Oximetry in Reducing Postoperative End Organ Dysfunction/Failure After Complex Non-Cardiac Surgery

The number of elderly patients requiring general anesthesia for major surgical procedures is increasing dramatically. It is estimated that 20% of these patients will develop major complications after surgery. Monitoring brain oxygen saturation may be helpful in reducing the postoperative complication rates. A decrease in brain oxygen is a sign that all other vital organs such as kidneys, heart, liver, and intestines have reduced blood supply and are starved from oxygen. This happens in 1 out of 5 patients undergoing major complex surgeries. Brain oxygen saturation monitor at this time is not used routinely during surgery, primarily due to the added cost, as well as, insufficient evidence that restoring the brain oxygen saturation to baseline would result in better outcomes. Patients will be randomly assigned to either study or control groups. In the study group, a special algorithm will be used to restore brain oxygen saturation. In the control group, the brain oxygen saturation will be monitored continuously, but the monitor screen will be electronically blinded, and standard clinical care applied. The objective of this study is to see if restoring the brain oxygen saturation to baseline results in less complication rates after surgery. The objective of this study is to reduce the incidence of postoperative morbidity due to end organ dysfunction after major non-cardiac surgery in elderly patients. The primary aim is to determine if restoration of rSO2 to baseline levels results in reduced incidence of major organ morbidity and mortality (MOMM). A secondary aim is to determine a cost-effectiveness of this monitoring modality.
