Ultrasound guided superficial cervical plexus block versus greater auricular nerve block for postoperative tympanomastoid surgery pain: A prospective, randomized, single blind study.

OBJECTIVES

The aim of the study was to investigate the effect of ultrasound guided superficial cervical plexus (SCP) block versus greater auricular nerve (GAN) block for on postoperative tympanomastoid surgery analgesia.

METHODS

In this prospective, randomized, single-blind study, a total of 50 patients aged between 25 and 70 years, those who were in the American Society of Anesthesiologists I-II class and underwent tympanomastoid surgery were included in the study. Patients were randomized to either Group Y: intravenous patient-controlled analgesia tramadol (IV PCA) + SCP block; n=25 and Group G: IV PCA + GAN block; n=25. Postoperative pain was evaluated at the 2nd, 6th, 12nd, and 24th hours using the Visual Analogue Scale (VAS) and postoperative 6th, 12nd, and 24th hour follow-up results were evaluated to identify the quantity of tramadol use.

RESULTS

The VAS scores at all measures time were found to be no statistically significant difference between groups (p>0.05). The amounts of PCA tramadol consumption at all measures time were significantly lower in Group Y than in Group G (p<0.05).

CONCLUSION

The results of this study have indicated that SCP and GAN blocks can be used for pain control after tympanomastoid surgery. We believe that the only disadvantage of SCP block application with lower amounts of tramadol use is that the complications that can occur are more serious than those that can occur in GAN application.
