Efficacy and safety of 1% ropivacaine for postoperative analgesia after lower third molar surgery: a prospective, randomized, double-blinded clinical study
Key Take-Away: 

The present study has shown that Ropivacaine (1%, 2 ml) was potent in tendering relief for postoperative analgesia after lower third molar surgery. Thus, it may prove to be clinically relevant in the selection of felicitous pain control regimen for both surgical procedure and early postsurgical treatment.

The purpose of this study was to investigate postoperative analgesic effect of ropivacaine administered as main or supplemental injection for the inferior alveolar nerve block (IANB) in patients undergoing lower third molar surgery.

The purpose of this study was to investigate postoperative analgesic effect of ropivacaine administered as main or supplemental injection for the inferior alveolar nerve block (IANB) in patients undergoing lower third molar surgery.

Methods: 

The double-blind randomized study comprised 72 healthy patients. All patients received two blocks, the IANB for surgical procedure + IANB after surgery for postoperative pain control, and were divided into three groups: (1) 2% lidocaine/epinephrine + 1% ropivacaine, (2) 2% lidocaine/epinephrine + saline, and (3) 1% ropivacaine + saline.

The occurrence of postoperative pain, pain intensity and analgesic requirements were recorded. Data were statistically analyzed using chi-square, Fisher, and Kruskal-Wallis tests and analysis of variance (ANOVA) with Bonferroni and Tukey correction.

Results: 

Ropivacaine was more successful than lidocaine/epinephrine in obtaining duration of postoperative analgesia, reduction of pain,

and analgesic requirements whether ropivacaine was used for surgical block or administered as a supplemental injection after surgery.

Conclusion: 

Ropivacaine (1%, 2 ml) resulted in effective postoperative analgesia after lower third molar surgery.

Since pain control related to third molar surgery requires the effective surgical anesthesia and postoperative analgesia, the use of 1% ropivacaine could be clinically relevant in a selection of appropriate pain control regimen for both surgical procedure and early postsurgical treatment.
