Abstract Background This study was designed to compare magnesium sulphate with dexmedetomidine, regarding their efficiency in inducing deliberate hypotension and providing a better surgical field exposure during middle ear surgery. It also compared the influence of their use on postoperative pain and recovery time. Methods Eighty-eight adult patients undergoing middle ear surgery were included. Patients were randomly divided into two equal groups. Patients were assigned to receive either… Expand
A comparative study of dexmedetomidine, magnesium sulphate, or glyceryl trinitrate in deliberate hypotension during functional endoscopic sinus surgery
TLDR
Both dexmedetomidine and magnesium sulfate offered the advantage of inherent analgesic and sedative effect, but at the expense of longer recovery of anesthesia and discharge from postanesthesia care unit. Expand
A Comparative Study between Magnesium Sulphate and Nitroglycerin with Propranolol in Controlled Hypotensive Anaesthesia during Middle Ear Surgeries
TLDR
The ability of magnesium sulphate and nitroglycerin with propranolol to induce deliberate hypotension in patients undergoing middle ear surgery is shown. Expand
Controlled hypotension for FESS: A randomised double-blinded comparison of magnesium sulphate and dexmedetomidine
TLDR
Dexmedetomidine is superior to MgSO4 in achieving target mean arterial pressure in lesser time with minimum infusion dose, and this study concluded that controlled hypotension in FESS is controlled. Expand
Magnesium sulfate versus nitroglycerin in controlled hypotensive anesthesia in middle ear surgeries
TLDR
Controlled hypotension was required for middle ear surgeries to achieve a bloodless operative field and improve its quality and magnesium sulfate was better as it provided optimum surgical field, less tachycardia, need less dose of propranolol with less post-operative pain in comparison to nitroglycerin. Expand
The effects of dexmedetomidine and magnesium sulphate in adult patients undergoing endoscopic transnasal transsphenoidal resection of pituitary adenoma: A double-blind randomised study
TLDR
During transsphenoidal pituitary resection, dexmedetomidine, compared to magnesium, is associated with lower blood loss and better operating conditions but with more hypotension and bradycardia. Expand
Efficacy of different dexmedetomidine regimens in producing controlled hypotensive anesthesia during functional endoscopic sinus surgery
TLDR
Assessment of the ability of dexmedetomidine in different regimens to produce controlled hypotensive anesthesia during functional endoscopic sinus surgery in adults and the need to add an additional hypotensive agent in the form of nitroglycerin to achieve the target MAP found it to be effective. Expand
Hypotensive anesthesia for the correction of scoliosis under total intravenous anesthesia: comparison between dexmedetomidine and magnesium sulfate
TLDR
TIVA with both dexmedetomidine and magnesium sulfate could achieve the target MAP for hypotensive anesthesia and can control MAP with lesser need for vasodilators and with better control of HR. Expand
Dexmedetomidine versus Nitroglycerin for Controlled Hypotensive Anaesthesia in Functional Endoscopic Sinus Surgery
TLDR
Dexmedetomidine and Nitroglycerine both can be used with great safety profile to achieve controlled hypotension during FESS, and there was no difference in amount of blood loss between the two groups. Expand
Effectiveness of dexmedetomidine in reducing blood loss during middle ear surgery under general anaesthesia: a randomized controlled trial
Background: Maintenance of relatively dry bloodless field is favoured by surgeons during middle ear surgery under operating microscope as it produces better visibility, ease of operation and reducesExpand

TLDR
It was concluded that both magnesium sulfate and lidocaine successfully induced controlled hypotension in patients undergoing FEES, but lidocane provided better surgical field clarity and shorter extubation time. Expand

Controlled hypotension for middle ear surgery: a comparison between remifentanil and magnesium sulphate.
TLDR
Both magnesium sulphate and remifentanil when combined with sevoflurane provided adequate controlled hypotension and proper surgical conditions for middle ear surgery, however, patients administered magnesium sulphates had a more favourable postoperative course with better analgesia and less shivering and PONV. Expand
Magnesium sulphate as a technique of hypotensive anaesthesia.
TLDR
Magnesium sulphate led to a reduction in arterial pressure, heart rate, blood loss and duration of surgery, and alters anaesthetic dose requirements and emergence time. Expand
Is it feasible to use magnesium sulphate as a hypotensive agent in oral and maxillofacial surgery
TLDR
The use of intravenous magnesium sulphate for deliberate hypotension is feasible in ASA 1 patients using a standard nitrous oxide, oxygen, isoflurane, opioid and muscle relaxant technique and the surgeons thought that the blood loss was less than when using other hypotensive anaesthetic techniques. Expand
Is it feasible to use magnesium sulphate as a hypotensive agent in oral and maxillofacial surgery?
TLDR
The use of intravenous magnesium sulphate for deliberate hypotension is feasible in ASA 1 patients using a standard nitrous oxide, oxygen, isoflurane, opioid and muscle relaxant technique and forms the basis for a larger controlled study where the issues of postoperative sedation and weakness and coagulopathy can be dealt with in greater detail.

Comparison between dexmedetomidine and remifentanil for controlled hypotension during tympanoplasty
TLDR
Infusion of dexmedetomidine, at the doses used in this study, was less effective than remifentanil in achieving controlled hypotension, good surgical field exposure condition and surgeons' satisfaction during tympanoplasty. Expand
Intrathecal Magnesium Prolongs Fentanyl Analgesia: A Prospective, Randomized, Controlled Trial
TLDR
Intrathecal magnesium prolongs spinal opioid analgesia in humans and suggest that the availability of an intrathecal N-methyl-d-aspartate receptor antagonist could be of clinical importance for pain management. Expand

TLDR
Magnesium sulphate controlled hypotension, reduced intraoperative pressure and provided good surgical conditions for choroidal melanoma resection with no need for additional use of a potent hypotensive agent in adults. Expand

Comparison of sodium nitroprusside- and esmolol-induced controlled hypotension for functional endoscopic sinus surgery
TLDR
The combined effects of increased venous drainage due to the reverse Trendelenburg position, hypotension as well as capillary vasoconstriction due to unopposed alpha-adrenergic effect on the mucous membrane vasculature in the esmolol group (as opposed to vasodilatation in the SNP group) probably caused the superior surgical conditions.
