Intra-articular infiltration of bupivacaine in arthroscopic knee surgery: Dexamethasone versus magnesium sulfate as adjuncts.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

The aim of their study was to assess the analgesic role of Dexamethasone or Magnesium Sulfate as adjuncts to intra-articular Bupivacaine after knee arthroscopic surgery.

Why It Was Studied

Knee arthroscopy is a common procedure in orthopedics due to its minimally invasive nature.

However, it often leads to moderate to severe postoperative pain, especially within the first 24 hours.

Who Took Part

The abstract describes 75 patients taking part.

The age groups tagged for this paper are adults and middle-aged adults, both men and women.

It was a prospective randomized double-blinded study including 75 adult patients classified according to the American Society of Anesthesiology (ASA) I-II and undergoing arthroscopic knee surgery under spinal analgesia.

Postoperative rescue analgesia was insured by a patient-controlled analgesia (PCA) morphine.

How the Study Was Run

The design is described as randomized and double-blind.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

They were divided into three groups of 25 each.

The primary outcome was morphine consumption during the first 24 hours after surgery.

What Was Measured

Topics PubMed links to this paper include Dexamethasone, Bupivacaine, Arthroscopy, Postoperative Pain, Magnesium Sulfate, Injections, Intra-Articular and Anesthetics, Local.

The authors tagged it with the keywords Analgesia, Intra-articular injection and Knee joint.
