A Study of Changes in Heart Function and Blood Flow in People Receiving Anesthesia
Changes in Loading Conditions on Induction of General Anesthesia: Mechanisms of Post-Induction Hypotension (PIH)
Memorial Sloan Kettering Cancer Center
250 participants
Jul 13, 2023
OBSERVATIONAL
Conditions
Summary
The purpose of this study is to understand changes in heart function (how the heart pumps blood) and blood flow in people who receive general anesthesia during surgery. The researchers are particularly interested in the heart function and blood flow changes in people who experience low blood pressure (hypotension) after receiving anesthesia.
Eligibility
Inclusion Criteria4
- Adult patients ≥ 18 years of age requiring general anesthesia for surgery
- Intubation required for anesthetic management / surgery
- Anticipated prep time before incision of 20 minutes
- Baseline MAP >70mmHg
Exclusion Criteria8
- History of coronary artery disease
- History of cardiac disease (e.g., HTN, arrythmias, valvular and structural abnormalities)
- History of peripheral artery occlusive disease
- Beta-blocker use
- Anti-hypertensive medication use
- Patients with epidural, spinal, paravertebral, serratus blocks preoperatively
- Patients requiring rapid sequence induction (where intubation occurs concurrently with induction)
- Emergency surgery
