Beschreibung
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)

Teilnehmergruppe / Arm |
Intervention / Behandlung |
---|---|
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.
|
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.
Andere Namen:
|
Kein Eingriff: 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.

Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Post-anaesthesia care unit (PACU) length of stay
Zeitfenster: From time of PACU admission until the time of transfer from PACU, assessed up to 48 hours.
|
Total time (minutes) from postoperative PACU admission to PACU discharge.
|
From time of PACU admission until the time of transfer from PACU, assessed up to 48 hours.

Sekundäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
---|---|---|
Post-randomization hospital length-of-stay
Zeitfenster: From date of randomization until the date of hospital discharge or death from any cause, whichever came first, assessed up to 4 weeks.
|
Number of days in hospital from study enrollment to discharge or death.
|
From date of randomization until the date of hospital discharge or death from any cause, whichever came first, assessed up to 4 weeks.
|
New ICU admission rates
Zeitfenster: From time of randomization to the immediate postoperative period, assessed up to 6 hours after the conclusion of surgery.
|
New admissions to ICU in the immediate post operative period in patients previously on the ward or in the emergency department.
|
From time of randomization to the immediate postoperative period, assessed up to 6 hours after the conclusion of surgery.
|
Rates of detection of unexpected or new pathologies
Zeitfenster: From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
New cardiac, pulmonary or gastric pathology detected by preoperative POCUS not known to be present previously.
Examples include valve lesions, resting regional wall motion abnormalities, ventricular dysfunction, ventricular hypertrophy, pulmonary edema, consolidation and/or pleural effusion.
This will be calculated only for participants randomized to the Scan Group.
|
From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
Change in anesthetic plan based on the scan result
Zeitfenster: From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
A survey will be administered to the anesthesiologist caring for the patient asking whether the POCUS exam findings influenced the anesthetic plan for the patient.
If the answer is "yes, it did influence the anesthetic plan", subsequent questions will explore how it influenced anesthetic management.
These will include questions of whether it influenced fluid management, anesthetic technique, choice of invasive lines, choice or dose of induction agents, or delay of surgery for optimization or further work-up.
This will be calculated only in participants randomized to the Scan Group.
|
From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
Intensiveness of operating room (OR) management
Zeitfenster: During OR time post randomization, assessed until the patient is transferred from the OR to PACU, up to 7 days from randomization.
|
Use of invasive lines i.e. arterial, central lines or TEE monitoring
|
During OR time post randomization, assessed until the patient is transferred from the OR to PACU, up to 7 days from randomization.
|
New or change in peri-operative diuretics use
Zeitfenster: From time of enrollment, up to 2 weeks from randomization.
|
New use or change in pattern of diuretic use in the pre, intra or post operative phases.
|
From time of enrollment, up to 2 weeks from randomization.
|
Rates of blood work ordered and imaging investigations
Zeitfenster: From time of enrollment, up to 2 weeks from randomization.
|
Frequency of post-randomization blood draws, frequency of post-randomization imaging studies (X-rays, CT's, MRI's, ultrasounds, echoes, and nuclear scans).
|
From time of enrollment, up to 2 weeks from randomization.
|
Mortality
Zeitfenster: From time of enrollment, up to 4 weeks from randomization.
|
In-hospital post randomization mortality rate.
Patients dying after transfer to another acute care hospital will also be counted as an in-hospital post randomization mortality.
|
From time of enrollment, up to 4 weeks from randomization.
|
Rates of adequately diagnostic focused cardiac ultrasounds, lung and pleural ultrasounds, and gastric volume/content assessments.
Zeitfenster: From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
An adequately diagnostic focused cardiac ultrasound will be defined as a scan having two or more views showing at least 3 cardiac chambers with diagnostic quality.
An adequately diagnostic lung and pleural scan will demonstrate a clear aeration pattern in both hemithoraces with visualization of the diaphragm or a corresponding curtain sign.
An adequately diagnostic gastric ultrasound will be done in right lateral decubitus and demonstrate the liver in the near field, a great vessel (aorta or IVC) in the far field, and the stomach antrum deep to the liver in the near to mid-field with visualization of the hypo-echoic muscularis propria.
These outcomes will be examined only in participants randomized to the Scan Group.
|
From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
|
Rates of OR delays for optimization or further work-up.
Zeitfenster: From time of randomization to the time of interpretation of the last POCUS scan, assessed up to 2 weeks from randomization.
