Abstract
Background:
Popliteal nerve blocks reduce pain and markedly improve postoperative outcomes during foot and ankle surgery; however, several potential complications may arise from nerve block procedures. The purpose of this study was to investigate local infiltration analgesia with ketorolac as a convenient alternative for pain relief.
Methods:
A total of 80 patients scheduled for hindfoot arthrodesis were randomly allocated to one of 2 anesthetic groups: a spinal block augmented with either a popliteal nerve block (n = 40) or local ketorolac and Marcaine infiltration (n = 40). Clinical assessment included postoperative visual analog scale (VAS) pain scores at 4, 8, 12, 24, and 48 hours, total morphine consumption, time to incision (time in operating room to incision), operative time, length of hospital stay, and complications.
Results:
Despite similar morphine consumption between groups (P = .28), VAS scores were significantly lower at 24 hours (1.6 ± 2.2 cm vs 2.7 ± 3.0 cm, P = .01) and 48 hours (0.2 ± 0.7 cm vs 1.0 ± 1.5 cm, P < .01) after surgery using local ketorolac injection. Although time from entry into the operating room to incision was also reduced after local ketorolac injection (19.0 ± 5.3 minutes vs 31.4 ± 14.6 minutes, P < .001), the length of operative time (P = .38), hospital stay (P = .43), and number of complications (P = .24) were similar between groups.
Conclusion:
Ketorolac local injection provided effective pain control in hindfoot arthrodesis and markedly reduced VAS pain scores up to 48 hours after surgery compared with popliteal nerve block. In addition, ketorolac local injection also reduced time in the operating room compared with popliteal nerve blockade.
Level of Evidence:
