Intraoperative Hypertension
Conditions
Brief summary
The study will evaluate the efficacy of bilateral infraorbital nerve block versus preoperative nasal packing with long-acting local anesthetic bupivacaine in term of maintaining hemodynamics intraoperative within 20% below baseline to achieve adequate hypotensive anesthesia and longer duration of postoperative analgesia up to 24 hours in patients undergoing transsphenoidal pituitary adenoma resection.
Interventions
the patients will receive bilateral infraorbital block
the patients will receive topical intranasal application of bupivacaine

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Mean arterial blood pressure | at the time of mucosal dissection |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intraoperative need for magnesium sulphate | the entire duration of surgery | Intraoperative need for iv magnesium sulphate up to 3 mg to maintain blood pressure 20% below baseline |
| Intraoperative need for fentanyl | the entire duration of surgery | Intraoperative need for iv fentanyl blouses 0.5 μg/kg (maximum total dose 5 μg/kg for the entire procedure) if no response to magnesium sulphate |
| Intraoperative need for nitroglycerine | the entire duration of surgery | Intraoperative need for iv nitroglycerine infusion (5 - 100 mic/min iv) if no response to magnesium sulphate and fentanyl |
| Postoperative need of pethidine | 24 hours postoprative | Postoperative need of pethidine boluses 25 mg with max.100 mg |
| Postoperative pain assessed by Numeric pain score | 24 hours postoprative | Pain score will be assessed postoperatively (using the verbal Numeric Rating Scale \[NRS\] 0-100; 0 = Non ,100 = Worst imaginable pain) |
