Postoperative effects of bilateral sphenopalatine ganglion blockade in septorhinoplasty operations; double-blind randomized clinical trial.

OBJECTIVE

We aimed to investigate the effect of bilateral sphenopalatine ganglion blockade (SPGB) on the main postoperative complications in septorhinoplasty operations.

METHODS

In this randomized, controlled, prospective study, 80 cases planned for Septorhinoplasty operations under general anesthesia were included in the study. The cases were divided into two groups; SPGB was performed with 2 mL of 0.25% bupivacaine bilaterally 15 min before the end of the operation in the SPGB group (Group S, n = 40). In the control group (Group C, n = 40), 2 mL of 0.9% NaCl solution was applied into both SPG areas. In the recovery unit after the operation; the pain and analgesic needs of the patients at 0, 2, 6 and 24 h were evaluated.

RESULTS

There was no statistically significant difference between the groups in terms of hemodynamic parameters (ASA, MBP, HR) (p > 0.05) All VAS values were statistically lower in Group S than in Group C (p < 0.05). In Group S, the need for analgesic medication was found in 5 cases between 0-2 h, whereas in Group C, this rate was found in 17 cases, and it was statistically significant (p < 0.05).

CONCLUSION

Bilateral SPGB application was determined to provide better analgesia in the early postoperative period compared to the control group, it was concluded that further studies are needed to say that there are significant effects on laryngospasm and nausea-vomiting.
