Spinal nerve blockade at the T4 level blocks autonomic input to the adrenal glands.
"You block the adrenals at T4, I mean, and below. So, you know, what happens when you're blocking the adrenals and then shooting up surgical stress because you're doing an incision?" (said at 0:21:40)
No published record matching the claim that spinal nerve blockade at the T4 level blocks autonomic input to the adrenal glands was located; this does not prove the claim false.
The average person in America undergoes nine surgical anesthetics in their lifetime.
"It's actually the average is nine surgeries in a lifetime. So the average in America person will have nine anesthetics in a lifetime." (said at 0:26:45)
No published record matching the claim that the average person in America undergoes nine surgeries or nine anesthetics in their lifetime was located; this does not prove the claim false.
Postoperative delirium incidence can reach up to 40% in elderly patients aged 65 and older, and up to 70% in open-heart or major surgeries.
"And delirium can be as high as 40% in some of these cases, up to 70% in open heart surgery or highly really major surgeries—70%." (said at 0:30:06)
No published record matching the claim that postoperative delirium incidence reaches up to 40% in elderly patients and up to 70% in open-heart or major surgeries was located; this does not prove the claim false.
Delirium typically lasts between 24 hours to 7 days.
"delirium is usually, you know, 24 hours to 7 days." (said at 0:32:20)
No published record matching the claim that delirium typically lasts between 24 hours to 7 days was located; this does not prove the claim false.
The 1999 Yale multidisciplinary delirium prevention study showed an economic impact of $7.3 million in hospital cost savings.
"They they showed an economic impact of $7.3 million in the '90s save like cost savings for a hospital." (said at 0:39:25)
No published record matching the claim that the 1999 Yale multidisciplinary delirium prevention study demonstrated $7.3 million in hospital cost savings was located; this does not prove the claim false. The landmark 1999 Yale trial evaluated a multicomponent intervention (the Hospital Elder Life Program) among 852 hospitalized older adults and reported clinical outcomes—specifically reducing the incidence of delirium from 15.0% to 9.9%—without reporting an economic impact figure of $7.3 million.

"We studied 852 patients 70 years of age or older who had been admitted to the general-medicine service at a teaching hospital. Patients from one intervention unit and two usual-care units were enrolled by means of a prospective matching strategy. The intervention consisted of standardized protocols for the management of six risk factors for delirium: cognitive impairment, sleep deprivation, immobility, visual impairment, hearing impairment, and dehydration."

"Fourteen economic evaluations (43% full, 57% partial) across nine multicomponent and nonpharmacological intervention types met inclusion criteria. The intervention costs ranged between US$386 and $553 per person in inpatient settings. Multicomponent delirium prevention intervention and the Hospital Elder Life Program (HELP) reported statistically significant cost savings or cost offsets somewhere else in the health system. Cost savings related to inpatient, outpatient, and out-of-pocket costs ranged between $194 and $6022 per person." (abstract, results, passage verified)

In 2016, The Wall Street Journal published an article stating that preoperative brain measurement is coming.
"The Wall Street Journal published an article in 2016 saying brain measurement is coming. Brain measurement pre-operatively is coming—2016." (said at 0:37:00)
No published record matching the claim that The Wall Street Journal published an article in 2016 stating that preoperative brain measurement is coming was located; this does not prove the claim false.
