Clinical Trial Summary

The endoscopic binostril transnasal transsphenoidal resection of pituitary procedures often cause intense pain which is difficult to suppress at the depth of conventional general anesthesia, resulting in severe hemodynamic fluctuations in patients. Infraorbital and infratrochlear nerve block can block the pain signal caused by the endoscopic binostril transnasal transsphenoidal resection of pituitary theoretically, which has been proven to provide satisfactory analgesia after septorhinoplasty. However, whether bilateral infraorbital and infratrochlear nerve block can provide stable hemodynamics and reduce the hemodynamic fluctuation the patients undergoing endoscopic binostril transnasal transsphenoidal resection of pituitary remains unclear.

Description:

Surgical stimulation is one of the important factors leading to hemodynamic fluctuation and affecting postoperative recovery quality. The endoscopic binostril transnasal transsphenoidal resection of pituitary procedures often cause intense pain because of there were numerous nerve endings at the surgical site which is originated from branches of the trigeminal nerve (including infraorbital and infratrochlear nerve). It's difficult to suppress intraoperative stimulation at the depth of conventional general anesthesia, resulting in severe hemodynamic fluctuations in patients. It's reported that pterygomaxillary fossa block can inhibit hypertension caused by surgical procedures, however the block may cause complications because of its complicated operations. Infraorbital and infratrochlear nerve block can block the pain signal caused by the endoscopic binostril transnasal transsphenoidal resection of pituitary theoretically, which has been proven to provide satisfactory analgesia after septorhinoplasty. However, whether bilateral infraorbital and infratrochlear nerve block can reduce the pain in the patients undergoing endoscopic binostril transnasal transsphenoidal resection of pituitary remains unclear. Therefore, the investigators propose the hypothesis that preoperative bilateral infraorbital and infratrochlear nerve block could effectively reduce the pain in patients undergoing endoscopic binostril transnasal transsphenoidal resection of pituitary. The objective of this study is to observe the heart rate and blood pressure at a specific point in time during the operation and pain at 2, 8, 24, 48 hours postoperatively between adult patients receiving or not receiving bilateral infraorbital and infratrochlear nerve block.

Intervention

Drug:
• nerve block with 0.5% ropivacaine
After general anesthesia, the patients will receive bilateral infraorbital and infratrochlear nerve block 30 minutes prior to surgery. Infraorbital nerve block is performed while using an extraoral approach. A 25-gauge needle was inserted laterally to the ipsilateral nostril after palpating the infraorbital ridge to locate the infraorbital foramen. The index finger of the non-dominant hand was positioned above the infraorbital foramen, and the needle was advanced until it was felt beneath the finger. 2 ml of the 0.5% ropivacaine slowly injected after negative aspiration of blood was confirmed. Inserting the needle 1 cm above the inner canthus, targeting the junction of the orbit and the nasal bone, performed infratrochlear nerve block. After negative aspiration of blood, 1 ml of the 0.5% ropivacaine was injected. Contralateral nerve block was performed in the same manner.

Other:
• without any nerve block
Patients receiving general anesthesia without Infraorbital and Infratrochlear nerve block.
