“…c RBC-M, the calculated blood loss is close to the Direct-M only when the blood dilution ratio was greater than 300 times reptilase, and aprotinin [24][25][26]. Second, taking advantage of bipolar radiofrequency (RF) heat coagulation is also a useful way to stop bleeding [27,28]. Venous plexus hemorrhage in the spinal canal and intervertebral foramen can be stopped by bipolar RF cautery.…”

Purpose: The purpose of this study is to come up with new methods to quantitate the blood loss under endoscope and explore the influence of blood loss on percutaneous endoscopic lumbar discectomy (PELD). Methods: Clinical research and in vitro experiment are combined. In the in vitro experiment, 2.0-ml blood was diluted in different ratio to simulate the rinse solution of PELD, the hematocrit method (HCT-M) and red blood cell count method (RBC-M) were came up to estimate blood loss and the new methods were calibrated with the direct measurement method (Direct-M). In clinical research, 74 patients with L5/S1 disk herniation were treated with PELD, and HCT-M and the empirical method (EMP-M) were used to estimate the blood loss under endoscope. According to blood loss, all patients were divided into group A (≤ 10 ml) and group B (> 10 ml). The blood loss, operation time, fluoroscopy frequency, visual analog scale (VAS), and Oswestry Disability Index (ODI) scores were compared between the two groups. Results: In the in vitro experiment, the hematocrit of the rinse solution was always stable over time. The estimated blood loss by HCT-M was stable and quite approximate to actual blood volume (2.0 ml) whatever the blood dilution ratio, while according to RBC-M, the estimated blood loss was close to the actual blood volume only when the dilution ratio was greater than 300 times. In clinical research, the blood loss estimated by HCT-M was higher than that by EMP-M in both groups (P < 0.05). There was a significant difference between group A and group B in blood loss (7.40 ± 1.61 vs 19.91 ± 10.94 ml), operation time (80.51 ± 34.70 vs 136.51 ± 41.88 min), and fluoroscopy frequency (6.92 ± 1.52 vs 11.11 ± 2.32 times) (P < 0.05). The VAS and ODI scores in group B were higher than that in group A 1 week after operation (P < 0.05); however, the scores were not different between the two groups at pre-operation (P > 0.05).

Conclusion: HCT-M is a reliable method to estimate endoscopic blood loss in PELD. The amount of endoscopic blood loss affects the operative procedure in operation time and fluoroscopy frequency, as well as clinical effects in VAS and ODI scores after operation in short-term

“…In radiofrequency thermocoagulation treatment, under the precise positioning of imaging and precise guidance of the navigation system, the electrode needle is introduced through the needle path, and the radiofrequency technology is used to output energy to act on the nucleus pulposus tissue, and directly denaturate, coagulate, contract and reduce the volume of nucleus pulposus in the diseased part of the herniated nucleus pulposus, and relieve the compression on nerve roots, and rarely damage the normal nucleus pulposus tissue, and at the same time repair the rupture of the annulus brosus, inactivated the newlydeveloped hypersensitive nerve terminals in the disc, and directly block the release of glycoprotein and β protein in the nucleus pulposus uid. The warming effect has a good therapeutic effect on the injured annulus brosus, edema of nerve root and in ammatory reaction in spinal canal [8][9] . Traditional Chinese medicine hook operation and small curved needle is a kind of painless and minimally invasive closed treatment method of traditional Chinese medicine bone injury, which is between operation, non-operation and intervention, with large strength, small di culty, small damage to patients, low cost, good effect and instant effect.…”

Background: This study aims to explore the clinical efficacy of radiofrequency ozone and injection of anti-inflammatory analgesic solution into the internal orifice of nerve root combined with traditional Chinese medicine hook operation in the treatment of lumbar disc herniation. Methods: The patients with lumbar disc herniation in our hospital from December 20, 2017 to June 19, 2019 were selected as the main research subjects, and the patients were numbered according to the order of their first visits, and the included patients were divided into treatment group and control group using random number table method. Patients in the treatment group were treated with radiofrequency ozone and injection of anti-inflammatory analgesic solution into the internal orifice of nerve root combined with traditional Chinese medicine hook operation. Patients in the control group were treated with traditional lumbar intervertebral disc radiofrequency treatment. The clinical treatment effects of the two groups were observed. Results: A total of 113 patients were included in this study, of which 73 were in the treatment group and 40 were in the control group. The results of the study showed that the NRS scores of patients in the treatment group before treatment were 5±1.68 points, and the NRS scores were 2±0.78 points, 1±0.54 points, and 1±0.77 points 1 month, 3 months, and 1 year after treatment, respectively. The NRS scores of patients in the control group were 3±0.48 points, 2±0.63 points, and 2±0.85 points 1 month, 3 months, and 1 year after treatment. Compared with before treatment and the control group, there were significant differences (P<0.01). Conclusion: Compared with single lumbar intervertebral disc radiofrequency treatment, radiofrequency ozone and injection of anti-inflammatory analgesic solution into the internal orifice of nerve root combined with hook operation can obtain good short-term and medium-term effects in the treatment of lumbar disc herniation. It is a safe and effective minimally invasive treatment method.
