Role of Intraoperative Endoscopic Sphenopalatine Ganglion Block in Sinonasal Surgery

Md. Hassan M. Ahmed and Md. Ehab H. Abu-Zaid
The present study evaluated the effect of bilateral endoscopic Sphenopalatine Ganglion Block (SPGB) combined with General Anesthesia (GA) for sinonasal surgery with respect to the blood loss, isoflurane consumption, hypotensive agent used, recovery time, postoperative pain and postoperative complications. Thirty patients were randomly allocated to receive GA alone (non-block group, n = 15) or combined GA and SPGB (block group, 15). The Mean Arterial Pressure (MAP) intraoperatively was maintained at 55-60 mm Hg. The consumption of isoflurane and the frequency of esmolol use were evaluated in both groups. The recovery time was recorded. A scoring system named Postoperative Respiratory System Evaluation Scoring (PRSES), was formed for evaluation of postoperative respiratory complications The pain intensity, postoperative tramadol consumption in both groups were also assessed. Intraoperatively, the isoflurane consumption was less in block group (p<0.001). The number of patients requiring esmolol was significantly higher in non-block group. Recovery time was longer in non-block group. PRSESs in all evaluation times were better in block group. In the PACU the total tramadol consumption was significantly reduced in block group (p≤0.005). Postoperative pain scores were lower in block group until 150 min. Other postoperative complications were more frequent in non-block group at all evaluation times. Bilateral SPGB combined with GA is effective in reducing blood loss, isoflurane consumption, hypotensive agent use, postoperative PRSESs 2-5, other complications, tramadol consumption and postoperative pain intensity in sinonasal surgery and associated with better recovery profiles and accepted surgeon and patient satisfaction.
