Detaljerad beskrivning
The main surgical treatment for pituitary adenomas is endoscopic trans-sphenoidal hypophysectomy.
Among the many regional blocks used is the sphenopalatine ganglion block (SPGB). It is one of the parasympathetic ganglia in the head, located in the pterygopalatine fossa, posterior to the middle nasal turbinate, 1-5 mm deep to the mucosa, anterior to the pterygoid canal and lateral to the sphenopalatine foramen.
This superficial location makes it easy to block the ganglion transnasally by topical anesthesia or by injection through many approaches including transnasal, intraoral, infrazygomatic and suprazygomatic approaches.

Primära resultatmått
Resultatmått |
Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Quality of surgical field visibility
Tidsram: Intraoperatively
|
Quality of surgical field visibility will be measured at the beginning of surgery and at 30 mins interval through a pre-defined average category scale (ACS) (from 0 to 5). The ideal category scale values for surgical conditions were pre-determined to be ≤3. 0=No bleeding
|
Intraoperatively

Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Intraoperative fentanyl consumption
Tidsram: Intraoperatively
|
The hemodynamic objective of the anesthetic plan is to maintain mean arterial pressure values between 60 mmHg and 65 mmHg to produce an optimal surgical field, this will be done by injection of increments of fentanyl (0.5 μg/kg) up to total dose of 3 μg/kg
|
Intraoperatively
|
|
Total dose of propranolol
Tidsram: Intraoperatively
|
In case of reflex persistent increase in heart rate (HR) >100 beats/min, i.v.
0.2 mg increments of propranolol will be given to maintain HR 60-70 beats/min.
|
Intraoperatively
|
|
Total dose of nitroglycerine
Tidsram: Intraoperatively
|
In case of reduction of mean arterial pressure (MAP), nitroglycerine infusion will be done through adjustment from 0.5 to 10 μg/kg/ min according to patient response.
|
Intraoperatively
|
|
Amount of intraoperative blood loss
Tidsram: Intraoperatively
|
Amount of intraoperative blood loss (by measuring the volume of blood in suction reservoir minus the normal saline used to wash the surgical field)
|
Intraoperatively
|
|
Degree of pain
Tidsram: 24 hours postoperatively
|
Each patient will be instructed about postoperative pain assessment with visual analog scale (VAS).
VAS (0 represents "no pain" while 10 represents "the worst pain imaginable").
VAS will be measured immediately after the operation, then at 2, 12, and 24hrs.
|
24 hours postoperatively
|
|
Time of 1st analgesia requirement
Tidsram: 24 hours postoperatively
|
Postoperative analgesia is performed with administration of paracetamol/acetaminophen (1 g three times a day) and visual analog scale (VAS) ≥4 will be managed by IV dose of 25mg pethidine.
|
24 hours postoperatively
|
|
Total meperidine consumption
Tidsram: 24 hours postoperatively
|
Total postoperative meperidine consumption will be recorded.
|
24 hours postoperatively
|
|
Incidence of postoperative side effects
Tidsram: 24 hours postoperatively
|
Incidence of postoperative side effects such as postoperative nausea and vomiting (PONV), headache, visual disturbances, agitation or somnolence will be recorded.
|
24 hours postoperatively
