Table 5 iPACK block
Year | Author | Type of study | Sample size | Method | Results |
|---|---|---|---|---|---|
2020 | Patterson et al. (2020) | A prospective single-center double-blind, randomized controlled trial | 69 | iPACK vs CACB | iPACK was more effective in reducing pain after TKA (p < 0.05) |
2021 | Akesson et al. (2021) | A prospective single-center double-blind, randomized controlled trial | 60 | iPACK vs genicular nerve block vs placebo | iPACK was as effective as a genicular nerve block in reducing pain after TKA (p < 0.05) |
2020 | Kampitak et al. (Kampitak et al. 2020) | A prospective, triple-blinded, randomized controlled trial | 105 | Proximal iPACK vs distal iPACK vs tibial nerve block | Proximal iPACK was less effective in reducing pain after TKA (p > 0.05) |
2021 | Kampitak et al. (Kampitak et al. 2021) | A prospective, randomized, double-blind study | 72 | Selective sensory nerve blockade (ACB + anterior femoral cutaneous nerve block + iPACK) vs PAI | SSNB did not provide superior postoperative analgesia |
