RESUMEN
Objective: To investigate the efficacy and safety of CT-guided radiofrequency ablation of posterior root of spinal nerve in the treatment of postherpetic neuralgia (PHN). Methods: A total of 102 PHN patients (42 males and 60 females) aged (69.7±9.4) years who underwent CT-guided radiofrequency ablation of posterior root of spinal nerve in the Department of Pain Medicine of the Affiliated Hospital of Jiaxing University from January 2017 to April 2020 were retrospectively included. Patients were followed up, and numerical rating scale (NRS) score, Pittsburgh sleep quality index (PSQI), satisfaction score and complications before surgery (T0) and at 1 d (T1), 3 months (T2), 6 months (T3), 9 months (T4) and 12 months (T5) after surgery were recorded. Results: The NRS score of PHN patients at T0, T1, T2, T3, T4, and T5 [M(Q1, Q3)] was 6(6, 7), 2(2, 3), 3(2, 4), 3(2, 4), 2(1, 4), 2(1, 4), respectively. Likewise, the PSQI score [M(Q1, Q3)] at aforementioned time points was 14(13, 16), 4(3, 6), 6(4, 8), 5(4, 6), 4(2, 8), 4(2, 9), respectively. Compared with T0, the NRS and PSQI scores at all time points from T1 to T5 were lower, with statistically significant differences (all P<0.001). The overall effective rate of surgery at 1 year postoperatively was 71.6% (73/102) with a satisfaction score of 8(5, 9), and the recurrence rate was 14.7% (15/102) with a recurrence time of (7.5±0.8) months. The main postoperative complication was numbness, with an incidence of 86.0% (88/102), and the degree of numbness gradually decreased with time. Conclusion: CT-guided radiofrequency ablation of posterior root of spinal nerve for PHN has a high effective rate and a low recurrence rate, with high safety profile, and may be a feasible surgical option for the treatment of PHN.

Objective: To investigate the efficacy and safety of pulsed radiofrequency of dorsal root ganglion combined with ozone injection on acute herpes zoster neuralgia in the neck and upper extremities. Methods: A total of 110 patients with acute phase herpes zoster neuralgia in the neck and upper extremities treated in the Department of Pain of Jiaxing First Hospital from January 2019 to February 2020 were retrospectively included. The patients were divided into two groups according to different treatment modalities: the pulsed radiofrequency group (group A, n=68) and the pulsed radiofrequency combined with ozone injection group (group B, n=42). In group A, there were 40 males and 28 females, aged (71.9±9.9) years, while group B consisted of 23 males and 19 females, aged (66.3±16.9) years. Patients were followed up, and numerical rating scale (NRS) score, dose of adjuvant gabapentin, incidence of clinically significant postherpetic neuralgia (PHN) and adverse effects were recorded preoperatively (T0) and at 1 d (T1), 3 d (T2), 1 week (T3), 1 month (T4), 2 months (T5), and 3 months (T6) postoperatively. Results: The NRS score of patients [M (Q1, Q3)] in group A at time points T0, T1, T2, T3, T4, T5 and T6 was 6 (6, 6), 2 (2, 2), 3 (3, 4), 3 (2, 3), 2 (2, 3), 2 (1, 3) , 1 (0, 2), respectively, while the NRS score at aforementioned time points in group B was 6 (6, 6), 2 (1, 2), 3 (3, 4), 3 (2, 3), 2 (2, 3), 2 (1, 3), 1 (0, 2), respectively. Compared with preoperative NRS scores, NRS scores decreased in both groups at all postoperative time points (all P<0.05). Compared with group A, the NRS scores of group B at time points T3, T4, T5, and T6 decreased more significantly, with statistically significant differences (all P<0.05). The dose of gabapentin in group A [M (Q1, Q3)] was 0.6 (0.6, 0.6), 0.3 (0.3, 0.6), 0.3 (0.0, 0.3) and 0.0 (0.0, 0.3) mg/d at time points T0, T4, T5, and T6, respectively, and 0.6 (0.6, 0.6), 0.3 (0.2, 0.3), 0.0 (0.0, 0.3) 0.0 (0.0, 0.0) mg/d in patients in group B, respectively. Compared with the preoperative period, the doses of gabapentin taken by patients in both groups reduced significantly at all postoperative time points (all P<0.05). Moreover, compared with group A, the gabapentin dose in group B decreased more significantly at time points T4, T5, and T6, with statistically significant differences (all P<0.05). The incidence of clinically significant PHN was 25.0% (17/68) and 7.1% (3/42) in groups A and B, respectively, and the differences were statistically significant (P=0.018). No serious adverse effects such as pneumothorax, spinal cord injury and hematoma were observed during the treatment period in both groups. Conclusion: Pulsed radiofrequency of dorsal root ganglion combined with ozone injection is safer and more effective for the treatment of acute phase herpes zoster neuralgia in the neck and upper extremities, and it can reduce the incidence of clinically significant PHN, with high safety profile.

Objective: To observe the clinical effects of CT-guided chemical destructive block of lumbar sympathetic nerve in the treatment of cold sensation of limbs. Methods: In this retrospective analysis, clinical data of 43 patients with cold sensation of limbs treated by lumbar sympathetic chemical destructive block in the Affiliated Hospital of Jiaxing University from January 2015 to January 2018 were collected. The changes of heart rate, non-invasive blood pressure (NIBP), oxygen saturation (SpO(2)), plantar temperature and peripheral perfusion index (PI) of patients were recorded and analyzed before treatment and 5 min after injection of anhydrous ethanol. The patients were followed up at postoperative 1 day, 1 week, 1 month, 3 months, 6 months, 1 year and 2 years. Results: Fourty-three patients underwent bilateral lumbar sympathetic nerve chemical destructive block under the CT-guided, and all patients were punctured to the target successfully. The PI of patients before and after treatment were 1.2±0.6, 7.2±3.0 respectively, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=12.386, P<0.05). The plantar temperature of patients before and after treatment respectively were (29.6±1.7)â, (34.6±1.1)â, which was significantly increased after treatment compared with before treatment, and the difference was statistically significant (t=15.057, P<0.05). There were no significant differences in heart rate, NIBP and SpO(2) between before and after treatment (all P>0.05). Lumbar sympathetic chemical destructive block was clinically effective in 39 patients (90.7%) and ineffective in 4 patients (9.3%). Among the 39 clinically effective patients, the curative effects were excellent in 29 cases and improved in 10 cases. Postoperative recurrence occurred in 10 cases (25.6%). The satisfaction rates of patients at 1 day, 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after operation were 93.0%, 90.7%, 86.0%, 76.7%, 69.7%, 65.1% and 53.4%, respectively. Conclusion: Lumbar sympathetic chemical destructive block is a safe and effective way for the treatment of cold sensation of limbs, which can improve the symptoms of cold sensation of limbs to some extent.

Objective: To investigate the effects of ultrasound-guided lateral and medial point blocks of thoracic paravertebral space on the rapid recovery of laparoscopic cholecystectomy. Methods: A total of 90 patients of either sex, aged 18-67 years, weighted 45.10-91.80 kg, of American Society of Anesthesiologists physical status â or â ¡, undergoing elective laparoscopic cholecystectomy were divided into two groups (n=45) using a random number table: lateral point group of thoracic paravertebral space (group A) and medial point group of thoracic paravertebral space (group B). Ultrasound-guided thoracic paravertebral nerve block was performed before induction of general anesthesia. The puncture point of group A was positioned as the intercostal block of the thoracic paravertebral space of the right side of T(6)-T(11), and the puncture point of the group B was positioned as the thoracic paravertebral body of the right side of T(6)-T(11) thoracic paravertebral space. The thoracic paravertebral block was performed with 2 ml of 0.75% ropivacaine per injection for a total of 10 ml. The visual analog scale (VAS) scores of resting pain and active pain at 4, 8, 12 and 24 h after operation were observed. The anus recovery time after surgery and perioperative hypotension were also recorded. Results: The blood pressures in group A were significantly higher than those in group B at 4, 8, 12 and 24 h after operation, which were(73±7) vs (70±7), (78±7) vs (74±7),(82±7) vs (79±7),and (87±7) vs (83±7) mmHg,and the differences were statistically significant (t=2.29, 2.54, 2.33, 2.37, all P<0.05). The VAS scores of resting pain and active pain in group A were significantly higher than those in group B, and the differences were statistically significant (Z=-2.29, -2.51, -2.21, -2.39, -2.53, -2.25, -2.30, -2.24, all P<0.05). The postoperative anal exhaust recovery time of the patients in group A was (21.8±1.9) min that was obvious lower than that in group B which was (22.7±1.9) min with statistically significant difference (t=2.12, P<0.05). There was no significant difference in the incidence of postoperative dizziness, nausea, vomiting, and pruritus (χ(2)=0.28, 0.72, 0.45, 0.21,all P>0.05). Conclusions: In the procedure of thoracic paravertebral block under the guidance of ultrasound, the closer blocking points are to the central axis of the spine, the better the postoperative analgesic effect, but the more obvious the postoperative blood pressure reduction and the longer the anal recovery exhaust time. The further away from the central axis of the spine, the more analgesic effect decreases, but the blood pressure decreases and the anal recovery time is relatively rapid.

Objective: To evaluate the value of radial and ulnar arteries hemodynamic changes by ultrasound in patients with primary palmar hyperhidrosis after thoracic sympathetic block. Methods: This was a prospective study, from January 2016 to September 2016, 23 patients with primary palmar hyperhidrosis were admitted to the First Hospital of Jiaxing City, Zhejiang Province, 92 arteries of these patients who underwent thoracic sympathetic block were enrolled into this study. Diameters, peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) of the radial and ulnar arteries were examined one day before and after the operation by color Doppler ultrasound. Spectral waveforms of these arteries were observed, and palms temperature (T), oxygen saturation (SpO(2)), perfusion index (PI) were also measured. Diameters, PSV, EDV, RI, T, SpO(2) and PI of the patients with PH were compared before and after the surgery. The effect of operation was also evaluated. Results: Before surgery, diameters and EDV of the radial and ulnar arteries of the patients with PH were(2.12±0.36) mm, (1.50±0.32) mm, (4.90±1.84) cm/s, (4.71±1.65) cm/s, respectively, after surgery, the diameter of the RA, UA and EDV were (2.45±0.54) mm, (1.87±0.44) mm, (9.37±1.69) cm/s and (9.12±1.54) cm/s, which were significantly increased.Before surgery, RI of the RA and UA of the patients were (0.85±0.05), (0.97±0.07) , respectively, after surgery, RI of the RA and UA were (0.57±0.04), (0.64±0.09), respectively, which were significantly decreased after surgery. The difference was statistically significant (t=-5.23, -2.33, -19.80, -14.68, 3.31, 3.48, all P<0.01). Before surgery, PSV of the RA and UA of the patients were (46.38±15.12) cm/s, (45.60±14.88) cm/s , respectively, after surgery, PSV of the RA and UA were (46.93±16.02) cm/s, (46.19±15.30) cm/s , respectively. The difference was not statistically significant (t=-0.23, -1.39, all P>0.05). Before surgery, T, SpO(2) and PI of the patients were(29.7±1.04) â, (93.24±2.23) %, (1.11±0.13) % , respectively, after surgery, T, SpO(2) and PI of the patients were (35.09±1.21) â, (98.10±1.34) %, (4.77±1.22)% , respectively. The difference was statistically significant (t=-20.174, -1.140, -23.601, all P<0.05). The symptoms of hyperhidrosis of the patients were disappeared immediately after the surgery in both hands. All of the patients were cured within 3 months and there was no severe complications. Conclusion: Thoracic sympathetic block increase Diameters and EDV but decrease RI of the radial and ulnar arteries of the patients with PH and increase the palms temperature. Artery diameters, EDV, and RI measured by ultrasound can be used as parameters to evaluate the effect of thoracic sympathetic block in patients with PH. It's objective, non-invasive and convenient.

Objective: To determine the dose-response relationship of ropivacaine for epidural block in early herpes zoster by CT guided. Methods: From January 2015 to February 2017, according to the principle of completely random digital table, 80 patients with early herpes zoster who were prepared for epidural block were divided into 4 groups(each group 20 patients): in group A the concentration of ropivacaine was 0.08%, in group B was 0.10%, in group C was 0.12% and in group D was 0.14%.Under CT guidance, epidural puncture was performed in the relevant section, mixing liquid 5.0 ml (with 10% iodohydrin)were injected into epidural gap.CT scan showed that the mixing liquid covered the relevant spinal nerve segmental.The numeric rating scale(NRS) values before treatment and at 30 minutes, the incidence of adverse reactions were recorded, and the treatment were evaluated. The response to ropivacaine for epidural block in early herpes zoster was defined as positive when the NRS values was less than or equal to one.The ED(50), ED(95) and 95% confidence interval (CI) of ropivacaine for epidural block in early herpes zoster guided by CT were calculated by probit analysis. Results: The NRS values before treatment were 5.00(4.00, 6.00), 5.00(4.25, 6.00), 5.50(5.00, 6.00) and 5.00(4.00, 6.00), the difference was no significant(Z=2.576, P=0.462). The NRS values at 30 minutes decreased and the effective rate of the treatment increased(χ(2)=8.371, P=0.004), following ropivacaine dose gradient increasing, they were 1.50(1.00, 2.00), 1.00(1.00, 2.00), 0.50(0.00, 1.00) and 0.00(0.00, 1.00), the difference was statistically significant (Z=17.421, P=0.001). There was one case in group C and four cases in group D were hypoesthesia, others were no significant adverse reactions occurred. The ED(50) and ED(95) (95%CI) of ropivacaine for epidural block in early herpes zoster guided by CT were 0.078%(0.015%-0.095%)and 0.157%(0.133%-0.271%), respectively. Conclusion: Ropivacaine for epidural block in early herpes zoster guided by CT is effective for neuropathic pain, with no significant adverse reactions.
