Study Details

Brief 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.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Patients aged >17 years
  • Undergoing urgent or emergent non-cardiac surgery classified as intermediate or high risk according to American Heart Association(AHA)/American College of Cardiology(ACC) guidelines.

These include vascular surgeries (supra or infra-inguinal), intraperitoneal surgeries, intra-thoracic surgeries, head and neck surgeries, spine surgeries, urologic surgeries, and proximal extremity orthopedic surgeries. Peripheral extremity surgeries (wrist or below, and ankle or below), in addition to appendectomies and cholecystectomy surgeries will be excluded from this study.

Exclusion Criteria:

  • Patients scheduled for elective or pre-booked surgeries
  • Patients undergoing cardiac surgeries
  • Patients undergoing low risk procedures e.g. endoscopic procedures, superficial skin, subcutaneous tissue, breast, ophthalmic, and ambulatory surgeries
  • Patients undergoing orthopedic peripheral extremity surgeries (e.g. ankle, wrist, hand, foot)
  • Patients who have had an echo during the current hospital admission prior to recruitment.
  • Patients where the investigator performing or over-reading the POCUS scan is required to participate directly in perioperative patient care (e.g. anesthesiologist co-investigator performing or over-reading scan is on-call for this emergency case)

Interventions and Outcome Measures

Arms

experimental: Scan group

Patients randomized to the scan group (intervention arm) will receive a preoperative point-of-care ultrasound (POCUS) exam as an adjunct to their preoperative assessment, the results of which will be disclosed to the anesthesiologist and the patient care team. This POCUS exam will include a focused cardiac ultrasound, a lung and pleural ultrasound, and a gastric volume and content ultrasound assessment. Patients randomized to this arm may also receive repeat POCUS exams as needed and as clinical conditions change. These repeat exams may be requested by the anesthesiologist or patient care team.

no intervention: No scan group

Patients randomized to no scan (control arm) will not receive a preoperative point-of-care ultrasound exam. Patients in this arm will receive the standard-of-care; a routine preoperative assessment and physical examination by their attending anesthesiologist.

Interventions

Scan

The preoperative point of care ultrasound includes a protocolized focused cardiac ultrasound, lung and pleural ultrasound and a gastric volume and content ultrasound assessment, all of which will be performed as an adjunct to the anesthesiologist's assessment. The result of this ultrasound examination will be disclosed to the anesthesiologist and patient care teams. Repeat ultrasounds may be done as the patient's clinical condition changes, or as requested by the anesthesiologist or patient care team.

Primary outcome measure

  • Post-anaesthesia care unit (PACU) length of stay [ Time Frame: From time of PACU admission until the time of transfer from PACU, assessed up to 48 hours. ]
