| Abstract | ||
| Backgrounds: In this study, we aimed to investigate the effect of 4 in 1 block technique, which provides blockage of the saphenous, obturator, sciatic and the nerve to vastus medialis with a single injection without the need for position change, on postoperative analgesia in knee surgeries. Our study was conducted in an observational, comperatively prospective study. A total of 62 patients who underwent knee surgery under spinal anesthesia were included in our study. In the recovery unit, they were divided into two groups according to the analgesia method; 4 in 1 block group and control group without any block. In the postoperative period, 2nd, 4th, 6th, 12th, 24th visual analog score (VAS), sensory block, rescue analgesics, quadriceps strength at 12th and 24th hours were questioned. Results: The VAS value at the 2nd, 4th, 6th and 12th hours was found to be significantly lower in the block group compared to the control group. In terms of side effects, nausea-vomiting was low in the block group. A total of 10 of 16 patients with nausea were in the control group, and 4 patients with vomiting, and 1 patient with sedation were also in this group. Conclusions: We observed that 4 in 1 block is effective on postoperative analgesia, reduces opioid consumption and related side effects in knee surgery. We believe that it can be used effectively as a part of multimodal analgesia in knee surgeries. | ||
