Surgery Clinical Trial - Perioperative Point-of-Care Ultrasound

Status Recruiting

Clinical Trial Summary

The goal of this study is to assess the impact of perioperative point-of-care ultrasound (POCUS) assessment on patient-important outcomes (e.g. hospital length of stay, length of stay in recovery, mortality etc.) and perioperative patient management strategies, in patients undergoing non-elective non-cardiac surgeries.

Clinical Trial Description

Preoperative patients undergoing emergency non-cardiac surgery will be approached for study recruitment and participation. Study participants will be randomized to receive, or not, a preoperative POCUS exam as part of their routine preoperative assessment. Patients randomized to receiving a POCUS exam will undergo a protocolized focused cardiac ultrasound, lung and pleural ultrasound and a gastric volume and content ultrasound assessment. Results of this exam will be disclosed to the anesthesiologist and primary care team. Randomization will be stratified by the presence of any sign(s) of cardiorespiratory failure. Signs of cardiorespiratory failure are defined as: systolic blood pressure <90 mmHg, heart rate>100, respiratory rate >24, Oxygen saturation <90%, requirement of supplemental oxygen or mechanical ventilation, new requirement of loop diuretics in current hospital admission, chest pain, newly diagnosed ECG changes, requirement of vasoactive drugs, signs of pre-renal azotemia (BUN:creatinine ratio >20). Outcome data will be collected prospectively. Investigators performing and interpreting the scan will disclose the results to the care team but will not participate in patient care. Primary and secondary outcome data collection will be performed by an investigator blinded to patient assignment. The primary outcome is post anesthetic care unit length-of-stay. The secondary outcomes are post-randomization hospital length of stay, number of operating room (OR) delays for optimization, alterations in anesthetic management (using a brief anesthesiologist-administered survey), intensiveness of OR management (invasive blood pressure monitoring, central venous pressure monitoring, intraoperative TEE), new peri-operative diuretic use, new intensive care admission rates, mortality during this admission, amount/frequency of postoperative investigations, rates of detection of new pathologies identified by preoperative POCUS exam and the rates of adequately diagnostic POCUS studies. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
