Anesthesia by Drip or by Gas Worked the Same for Surgery Recovery

CATEGORY: HEALTHY AGING & LONGEVITY

Anesthesiologists have debated for years which way of keeping a patient under serves them better: a continuous intravenous drip of propofol, or the traditional anesthetic gases. A large UK trial set out to answer it in adults 50 and older having major planned surgery, and the answer was a tie. Patients in both groups spent a median of 24 of their first 30 days alive and at home, and rates of delirium, complications and death stayed level between the groups for six months.¹

Forty-nine hospitals, 2,508 operations, one coin-flip question

The VITAL trial enrolled 2,508 patients across 49 NHS hospitals, all 50 or older and all facing major non-heart surgery such as bowel, joint or cancer operations. Which anesthetic each person got was settled by randomization, not by their anesthesiologist’s habit or preference. Half received total intravenous anesthesia, the propofol drip. Half received general anesthesia by inhaled gas, usually sevoflurane or isoflurane. The researchers then counted something a patient actually feels: days alive and at home over the first month, a measure that drops when recovery goes badly, a complication sends someone back, or worse. Funding came from the UK’s public health-research agency, with no drug or device company involved.

The gaps that didn’t open

The researchers expected a winner. Their stated hypothesis was that the intravenous approach would prove superior. It didn’t. Delirium in the first days after surgery, a real fear for older patients and their families, occurred in 6.4% of the drip group and 6.7% of the gas group. About one in eight in each group had at least one significant complication within 30 days. Deaths were uncommon and similar out to six months. The one consistent difference was comfort on the day after surgery: nausea or vomiting affected 27% of the drip group versus 36% with gas, and thirst and hoarseness followed the same pattern. On the other side of the ledger, the only two cases of probable awareness during surgery both happened with the drip.

Key Takeaways

• For adults 50 and older having major planned surgery, intravenous and gas anesthesia produced the same recovery: a median 24 of the first 30 days alive and at home either way.
• Delirium, complications and deaths were just as common with one technique as the other, through six months of follow-up.
• The intravenous drip left fewer patients nauseated the next day (27% vs 36%), while both of the trial’s two cases of probable awareness under anesthesia occurred with the drip.
