TRIAL DESCRIPTION
Public title Dexmedetomidine versus magnesium in thoracoscopy.
Official scientific title Dexmedetomidine versus Magnesium Sulphate as a Co-analgesic in Video-assisted Thoracoscopy
Brief summary describing the background and objectives of the trial Video-assisted thocic surgery continues to gain acceptance for diagnostic and therapeutic procedures involving the lung or adjacent organs. Video-assisted thoracoscopic surgery (VATS), which is known to be less invasive than conventional thoracotomies, causes little pain and better preservation of pulmonary function. While (VATS) procedures are still associated with a significant amount of postoperative pain Opioids are the principle analgesic, but it can have several well-known dose related side effects Dexmedetomidine is a potent and highly selective ¿2 adrenoreceptor agonist with sympatholytic, sedative, amnesic, and analgesic properties Magnesium is a non-competitive (NMDA) receptor antagonist with antinociceptive effects. Objective: To compare the efficacy of dexmedetomidine versus magnesium sulphate in video-assisted thoracoscopic surgeries, regarding the reduction of opioid consumption.
