Objective To investigate the status quo of knowledge and attitude towards pain among medical staff in West China Hospital of Sichuan University. Methods The medical staff in Emergency Department of West China Hospital of Sichuan University were investigated by the Chinese version of Knowledge and Attitudes Survey Regarding Pain (2008) questionnaire, the contents of which related to pain assessment, pain related knowledge, analgesic related knowledge, and comprehensive application, etc. And the questionnaire scores were compared among medical workers with different background. Results A total of 156 questionnaires were sent out and 130 valid ones were taken back, with an effective recovery rate of 83.3%. There was no statistically significant difference in questionnaire scores among the medical workers with different education background or different professional titles (P>0.05). The questionnaire scores were significantly different among nurses with different seniority (F=3.785, P=0.035), and the mean score of the nurses with more than 10 years of seniority was the highest (22.78±7.11). The questionnaire scores were significantly different among nurses working in different areas (F=3.043, P=0.033), and the mean score of the nurses working in rescue room was the highest (24.53±7.84).The erroneous items were concentrated on item 5, 17, 19. In the answers to the open questions, 97.7% (127/130) thought that the existing pain knowledge could not satisfy the needs of clinical work; 100.0% (130/130) believed that it was necessary to study pain related knowledge; 80.0% (104/130) acquired pain related knowledge from clinical experience, 40.0% (52/130) from books, 15.4% (20/130) from the network; 90% ( 117/130) commonly used numeric rating scale to evaluate the patients’ pain degree, 20.0% (26/130) evaluated the patients’ pain degree through facial expressions. Conclusions The overall level of pain management knowledge and attitude in medical staff in Emergency Department is low. The continuing education on pain knowledge should be strengthened, the attitude towards pain treatment and the importance of pain management should be paid more attention, and the standardized training and supervision should be enhanced.
Objective To compare and analyze the occurrence of acute and chronic pain after subxiphoid and transcostal thoracoscopic extended thymectomy. MethodsA retrospective analysis was performed on 150 patients who underwent thoracoscopic extended thymectomy in our hospital from July 2020 to June 2022, among whome 30 patients received subxiphoid video-assisted thoracic surgery, and 120 patients received transcostal video-assisted thoracic surgery. The patients were matched by the propensity score matching method. Postoperative pain was evaluated by numeric rating scale (NRS). The intraoperative conditions and postoperative pain incidence were compared between the two groups. ResultsAfter matching, 60 patients were enrolled, 30 in each group, including 30 males and 30 females with an average age of 50.78±12.13 years. There was no difference in the general clinical data between the two groups (P>0.05), and no perioperative death. There were statistical differences in the intraoperative blood loss, postoperative drainage volume, postoperative catheter duration, postoperative hospital stay, postoperative pain on 1 d, 2 d, 3 d, 7 d, 3 months and 6 months after the surgery (P<0.05), but there was no statistical difference in the operation time or the postoperative 14 d NRS score (P>0.05). Further univariate and multivariate analyses for postoperative chronic pain showed that surgical method and postoperative 14 d NRS score were risk factors for chronic pain at the 3 months and 6 months after the surgery (P<0.05). Conclusion The subxiphoid thoracoscopic extended thymectomy has advantages over transcostal thoracoscopic surgery in the postoperative acute and chronic pain.
Objective To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies. Methods A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI. Results All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences (P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up (P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up. Conclusion For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.
ObjectiveTo evaluate the short-term effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in treatment of buttock pain associated with lumbar disc herniation.MethodsBetween June 2015 and May 2016, 36 patients with buttock pain associated with lumbar disc herniation were treated with PELD. Of 36 cases, 26 were male and 10 were female, aged from 18 to 76 years (mean, 35.6 years). The disease duration ranged from 3 months to 10 years (mean, 14 months). The location of the pain was buttock in 2 cases, buttock and thigh in 6 cases, buttock and the ipsilateral lower extremity in 28 cases. Thirty-four patients had single-level lumbar disc herniation, and the involved segments were L4, 5 in 15 cases and L5, S1 in 19 cases; 2 cases had lumbar disc herniation at both L4, 5 and L5, S1. The preoperative visual analogue scale (VAS) score of buttock pain was 6.1±1.3. VAS score was used to evaluate the degree of buttock pain at 1 month, 3 months, 6 months, and last follow-up postoperatively. The clinical outcome was assessed by the modified MacNab criteria at last follow-up.ResultsAll patients were successfully operated and the operation time was 27-91 minutes (mean, 51 minutes). There was no nerve root injury, dural tear, hematoma formation, or other serious complications. The hospitalization time was 3-8 days (mean, 5.3 days). All incisions healed well and no infection occurred. Patients were followed up 12-24 months (median, 16 months). MRI examination results showed that the dural sac and nerve root compression were sufficiently relieved at 3 months after operation. Patients obtained pain relief after operation. The postoperative VAS scores of buttock pain at 1 month, 3 months, 6 months, and last follow-up were 1.1±0.6, 0.9±0.3, 1.0±0.3, and 0.9±0.4 respectively, showing significant differences when compared with preoperative VAS scores (P<0.05); there was no significant difference in VAS score between the different time points after operation (P>0.05). At last follow-up, according to the modifed MacNab criteria, the results were excellent in 27 cases, good in 9 cases, and fair in 2 cases, and the excellent and good rate was 94.4%.ConclusionPELD can achieve satisfactory short-term results in the treatment of buttock pain associated with lumbar disc herniation and it is a safe and effective minimally invasive surgical technique.
Objective To explore the cause and treatment of chronic pain after tension-free repair of inguinal hernia. Methods 〗The clinical data of 426 cases with inguinal hernia underwent the tension-free hernioplasty during February 2002 to September 2007 were retrospectively analyzed. Results 〗Tension-free hernioplasty was performed to all patients. According to operative methods, they were divided into two groups: polypropylene filling group (n=210) and expanded polytetrafluoroethylene (e-PTFE) mycromesh group (n=216). The chronic pain rate after operation, polypropylene filling group (9.0%, 19/210) was significantly higher than e-PTFE mycromesh group (4.2%, 9/216)， P＜0.05. Conclusion 〗The tension-free repair by e-PTFE mycromesh has less pain in the inguinal hernia due to the material is more suitable to human physiology, more soft and light, with less complications.
ObjectiveTo systematically review the efficacy of zoledronic acid (ZOL) on postoperative osteoporosis vertebral fracture (OVFs) of patients undergoing percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP).MethodsWe searched databases including PubMed, EMbase, CBM, CNKI, VIP and WanFang Data to collect randomized controlled trials (RCTs) about ZOL on postoperative OVFs of patients undergoing PVP or PKP from inception to June 30th, 2016. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then, RevMan 5.3 software was used for meta-analysis.ResultsA total of 11 RCTs involving 950 cases of OVFs were included. The results of meta-analysis showed that: the bone mineral densities of the ZOL group at 6 months (SMD=0.62, 95%CI 0.06 to 1.18, P=0.03) and 12 months (SMD=1.32, 95%CI 0.62 to 2.02, P=0.000 2) after the operation were higher than those of the control group. The re-fracture risk of the ZOL group was lower than that of the control group (RR=0.27, 95%CI 0.16 to 0.47, P<0.000 01). The visual analogue scales of the ZOL group were lower than those of the control group at 3 weeks (SMD=–1.03, 95%CI –1.42 to –0.63, P<0.000 01), 1 month (SMD=–1.57, 95%CI –2.30 to –0.83, P<0.000 01), 3 months (SMD=–1.53, 95%CI –2.20 to –0.86, P<0.000 01), 6 months (SMD=–2.59, 95%CI –3.42 to –1.76, P<0.000 01), and 12 months (SMD=–2.69, 95%CI –4.21 to –1.18, P=0.000 5) after the operation. In addition, Oswestry disability index (ODI) score of the ZOL group was better than that of the control group at 1 year after the operation (SMD=–1.61, 95% CI–2.42 to –0.81, P<0.000 1).ConclusionsThe current evidence shows that the usage of ZOL after PVP/PKP has better effects, it relieves the pain further, increases the quantity of bone significantly, ameliorates the BMD, reduces the incidence of re-fracture and improves the quality of life. Due to the limited quantity and quality of included studies, more high-quality studies are needed to verify the above conclusion.
The scientific understanding of pain has stayed on a traditional classic “pain pathway” for many years. However, with the continuous progress of clinical diagnosis, this pathway obviously cannot explain all pain phenomena, and the understanding and interpretation of pain needs to be updated. Based on the influence of comprehensive medicine based on philosophy and the continuous summary and research of clinical cases of somatic symptoms, this paper takes the biological defense mechanism as the basic starting point, analyzes the position of pain in the biological defense mechanism, and reinterprets and defines pain from the new point of view of comprehensive medicine with the new perspective of biological defense mechanism. In addition, this paper also presents the new treatment principles of pain according to the occurrence mechanism through the perspective of biological defense and psychosomatic mechanism, and puts forward new principles of treatment and the view that “defense” is the fundamental purpose of all biology, aiming to provide a reference for the reinterpretation of more diseases and the research on the nature of biological behavior.
ObjectiveTo estimate postoperative pain and use of analgesic of patients who underwent video-assisted thoracoscopic surgery(VATS) or robotic assisted thoracoscopic surgery(RATS). MethodsFrom October 2014 through August 2015, 339 patients were treated by surgery in Shanghai Chest Hospital. Among them, 116 patients with intrathoracic lesions who underwent RATS with the da Vinci? Surgical System were as a RATS group with 51 males and 65 females at age of 52.59±11.49 years. Another 223 patients by VATS were as a VATS group with 93 males and 130 females at age of 58.00±10.56 years. We recorded the data of the VAS score and use analgesic of the patients after surgery. ResultsThere was a significant difference in VAS score between the RATS group and the VATS group(3.01±0.18 vs. 5.19±0.14, P<0.05). Astatistical difference of analgesic use between RATS and VATS was also found(1.09±0.12 vs. 1.77±0.10, P<0.05). ConclusionCompared with VATS, the postoperative pain of the patients who underwent RATS is lighter. And the use of analgesic is less.
Objective To investigate the effects of pain specialist nurse training (PSNT) on nurse’s pain management knowledge and attitude. Methods By distributing the “questionnaire of pain management knowledge and attitude”, 95 certified nurses, who were from 24 hospitals of different levels in Sichuan, Chongqing, Yunnan and Xinjiang, were investigated to survey their knowledge and attitude changes before and after PSNT. The data were analyzed by t-test. Results A total of 190 questionnaires were distributed to 95 nurses, and 190 returned, with a effective response rate of 100%. The result showed that, the total score after training (34.00±5.30) was significantly higher than that before training (17.58±4.00), with a significant difference (P=0.000). Conclusion The pain specialist nurse training can improve nurses’ knowledge and their attitudes on pain management.
