Effects of Compound Lidocaine Cream on Postoperative Pain After Endoscopic Sinus Surgery / 中国微创外科杂志

ABSTRACT

Objective To explore the effects of compound lidocaine cream applied to postoperative wound and nasal packing on postoperative sinus pain after endoscopic sinus surgery . Methods From April 2015 to June 2016, 100 cases of endoscopic sinus surgery were carried out in our hospital under general anesthesia .The patients were randomly divided into two groups , with 50 cases in each group .The group A was given compound lidocaine cream 4 g on the nasal surgery wound and medical inflation sponge for intranasal packing;the group B was given saline 4 g on the nasal surgery wound and medical inflation sponge for intranasal packing . The heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at the time of extubation (T0), 1 h after extubation (T1), 4 h after extubation (T2), 10 h after extubation (T3), and 12 h after extubation (T4), respectively.The visual analogue scale (VAS) of pain after extubation was recorded . Results The HR, SBP and DBP at T0, T1, T2 and T3 in the group A were significantly lower than those in the group B (P0.05), while the DBP was significantly lower in the group A than that in the group B (t=-2.562, P=0.012).The VAS scores were significantly lower in the group A than those in the group B at T 0, T1, T2 and T3 (P=0.000).No statistical difference was seen in VAS scores at T4 between the two groups (t=-1.199, P=0.233). Conclusions Application of compound lidocaine cream on nasal endoscopic wound and intranasal packing can effectively relieve the pain after endoscopic sinus surgery .The method has good analgesic effects and is worthy of popularization and application .
