Effect of pretreatment with magnesium sulphate on the duration of intense and deep neuromuscular blockade with rocuronium: A randomised controlled trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

To determine the role of magnesium sulphate on the duration of rocuronium-induced deep and intense NMB, and the period of no response to nerve stimulation.

Why It Was Studied

Magnesium sulphate is an important adjuvant drug in multimodal anaesthesia.

In combination with rocuronium it can enhance neuromuscular blockade (NMB).

Who Took Part

The study group was 60 patients.

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

All patients between 18 and 65 years of age scheduled to undergo elective otorhinolaryngological surgery, with a BMI between 18.5 and 24.9 kg m and an American Society of Anesthesiologists physical status classification of I or II.

How the Study Was Run

The design is described as randomized and double-blind.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the patients nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

A public tertiary care hospital, Rio de Janeiro, Brazil, from February 2017 to March 2018.

Neuromuscular function was measured by TOF-Watch SX monitor.

What Was Measured

The subject headings attached to it are Anesthetics, Brazil, Magnesium Sulfate, Neuromuscular Blockade, Neuromuscular Nondepolarizing Agents, Otorhinolaryngologic Surgical Procedures and Rocuronium.
