The Effect of Adding Either Propofol or Ketamine to Magnesium and Lidocaine Infusions in Nasal Surgeries.

The Effect of Adding Either Propofol or Ketamine to Magnesium and Lidocaine Infusions As an Opioid Free Anaesthesia on Surgical Field in Patients Undergoing Nasal Surgeries. a Randomized Controlled Trial

Nasal surgeries are common day case procedures. Although surgical complications are rare, bleeding decreases surgical field visibility and may cause vascular, orbital or intracranial complications in addition to failure of procedure. So, it is crucial to maintain hypotensive anaesthesia to optimize the surgical field.

In this study the investigators compare the effect of; propofol- lidocaine-magnesium and ketamine- lidocaine- magnesium infusions to dexmedetomidine- lidocaine- magnesium infusion on surgical field quality, intraoperative haemodynamics, surgical time, recovery time, sedation score, time to first rescue analgesic and incidence of PONV in patients undergoing nasal surgeries
