NCT06353529

Brief Summary

To assess the benefit of using an additional nerve block during minimally invasive pituitary surgery, to improve pain management after surgery. The medication (Bupivacaine) or a placebo (saline) will be injected during surgery and patients will be asked about their level of pain at multiple time points in the first 24 hours following surgery. Some patients will be randomized to a third, sham group that do not receive any additional injection. The aim is to improve patient outcomes and reduce the need for pain medication after surgery.

Study Arms (3)

Bupivacaine injection

EXPERIMENTAL

This group will receive bilateral injection of 0.5% bupivacaine with 1:200,000 epinephrine using a 20G needle and comprising 2mL of fluid on each side (4mL total) into the sphenopalatine ganglion.

Drug: Bupivacaine-Epinephrine 0.5%-1:200,000 Injectable Solution

Placebo Control

PLACEBO COMPARATOR

This group will receive bilateral injection of 0.9% saline solution using a 20G needle and comprising 2mL of fluid on each side (4mL total) into the sphenopalatine ganglion.

Drug: Placebo

Sham - no injection

SHAM COMPARATOR

Participants randomized to this arm will not receive any additional study injections and will undergo the current standard procedure for patients undergoing endoscopic endonasal surgery.

Drug: Sham Comparator

Interventions

2mL injection bilateral (4mL total) of 0.5% bupivacaine with 1:200,000 epinephrine solution, 20G needle, sterile, sphenopalatine ganglion; nerve block

Bupivacaine injection

2mL injection bilateral (4mL total) 0.9% saline solution, 20G needle, sterile, sphenopalatine ganglion; nerve block

Placebo Control

Participants receive no additional study injections

Sham - no injection
