BackgroundPain is the major determinant factor which affects the quality of recovery and postoperative agitation following nasal surgery with the patient under general anesthesia. Our objectives were to test the hypothesis that an external nasal nerve block will decrease pain intensity, decrease drug consumption, decrease the incidence of postoperative emergence agitation and improve quality of recovery.Material And MethodsIn this study 100 adult patients who were scheduled for elective external nasal surgery with the patient under general anesthesia and nasal packing on each side, received external nasal nerve blocks postoperatively for 24 h with saline (group I) or 2% xylocaine (group II) with 1:200,000 epinephrine. Postoperative pain was measured at the postanesthesia care unit (PACU) utilizing a visual analog scale (VAS). Narcotics consumption was also measured. Emergence agitation and quality of recovery were also assessed.ResultsPain scores were statistically significant between both groups. Requirements of equivalent morphine doses in the PACU were lower in group II (block) than group I (control) with a significant P value <0.001. Group II (block) patients required significantly less intraoperative fentanyl than group I (control) patients (p = 0.001). Group II (block) showed higher scores in pain dimension of QoR-40 in comparison with group I (P <0.001). The incidence of emergence agitation was lower in group II (block) than in group I (control, 24% vs. 48%, P = 0.012).ConclusionExternal nasal nerve block is an effective technique for reducing postoperative pain, drug consumption and quality of recovery. It also reduces emergence agitation. The effects are mainly due to profound analgesia and effective pain control that lead to decreased drug usage and reduced discomfort.
