Peripheral Nerve Block as a Supplement to Light or Deep General Anesthesia in Elderly Patients Receiving Total Hip Arthroplasty: A Prospective Randomized Study.

What Was Tested

The paper reports a study of Copper (Supplement), published as a randomized controlled trial.

Peripheral nerve block combined with general anesthesia is a preferable anesthesia method for elderly patients receiving hip arthroplasty.

The depth of sedation may influence patient recovery.

Who Took Part

The age groups tagged for this paper are older adults, both men and women.

Patients aged 65 years and older undergoing total hip arthroplasty were randomized into 3 groups: a general anesthesia without lumbosacral plexus block group, and 2 general anesthesia plus lumbosacral plexus block groups, each with a different level of sedation (light or deep).

Postoperative delirium and early postoperative cognitive dysfunction were assessed using the Confusion Assessment Method and Mini-Mental State Examination, respectively.

How the Study Was Run

The researchers set it up as a randomized study.

Random assignment meant chance, not the researchers, decided who got Copper (Supplement) and who got the comparison, which limits bias.

The extubation time and intraoperative consumption of propofol, sufentanil, and vasoactive agent were recorded.

Postoperative analgesia was assessed by the consumption of patient-controlled analgesics and visual analog scale scores.

What Was Measured

Therefore, the researchers investigated the influence of peripheral nerve blockade and different intraoperative sedation levels on the short-term recovery of elderly patients receiving total hip arthroplasty.
