Value of Epidural Injection of Hydromorphone for Postoperative Analgesia after Cesarean Section

Objective To explore the value of epidural injection of hydromorphone for postoperative analgesia after cesarean section.Methods 98 patients with cesarean section in our hospital from April 2019 to April 2020 were selected and divided into observation group and control group according to the order of admission.The control group was given a large dose of0.6 mg hydromorphone,and the observation group was given a small dose of 0.4 mg hydromorphone.The postoperative pain score,postoperative complications,and patients’recognition of analgesia were compared between the two groups.Results The pain scores of the observation group were(2.30±0.45),(2.50±0.33),(2.98±0.73)at 4 h,8 h,and 12 h after operation,which were better than those in the control group.The analgesic satisfaction of the observation group was 93.88%,and that of the control group was 71.43%.The analgesic effect of the observation group was better,and the incidence of postoperative complications was 10.20%in the observation group and 26.52%in the control group.The situation of SAS and SDS in the observation group was better than that in the control group(P<0.05).Conclusion The use of a small dose of 0.4 mg hydromorphone epidural injection,can effectively improve postpartum pain of puerpera,and improve satisfaction of maternal analgesia,while reducing the incidence of postoperative complications of maternal,with clinical research value,worthy of promotion in clinical medicine.

Ultrasound, Fluoroscopic-Guided Caudal, Lumbar Epidural Steroid Injections and Blinding Paraspinal Lumbosacral Steroid Injections in Patients with Low Back Pain with Radiculopathy

Background and Aims: Low back pain (LBP) is considered one of the most common health conditions in the world right now, and it affects many individuals throughout different stages of their lives. Chronic LBP (CLBP) was estimated to be between 5% and 10%, defined as LBP that lasts for 12 weeks. The most common causes of CLBP with radiculopathy are lumbar disc prolapse (LDP) and degenerative facet osteoarthropathy (DFO);the aim of this study is to investigate the efficacy of ultrasound (US) guided, fluoroscopy (FL) guided, Caudal Epidural Steroid Injection (CESI), lumbar epidural steroid injections (LESI), and blinding lumbosacral steroid injections (LSPSI) in patients with CLBP with radiculopathy. Patients and Methods: This is a randomized prospective study that was conducted at the department of rheumatology at Al Azhar University Hospital in Egypt between November 2020 and August 2021. A total of 100 patients with refractory CLBP with radiculopathy were enrolled in the study. Consequently, they were divided into 2 groups: the first consisted of fifty patients with CLBP and radiculopathy caused by LDP, as determined by lumbosacral magnetic resonance imaging (MRI), and the second group consisted of fifty patients with refractory low back pain and radiculopathy caused by DFO, as determined by lumbosacral plain x-rays and lumbosacral MRI. The following procedures were performed: US-guided CESI, FL-guided CESI, FL-guided LESI, US-guided LESI, and blinding LSPSI. Results: In the LDP group, there is a statistically significant difference between considered spinal nerve roots as regards Visual Analogue Scale (VAS) (at 2 months). Likewise, a statistically significant difference was found between blinding LSPSI and US-Guided LESI with respect to VAS (baseline) and VAS (2 months) (P-value = 0.018 and 0.003, respectively). Statistically significant differences were reported in VAS (2 months) for both FL-guided LESI and FL-guided CESI groups. Considering the VAS of studied spinal nerve roots in the DFO group, there is a statistically significant difference between the examined spinal nerve roots with respect to Oswestry Disability Index (ODI) (2 months). Similarly, there is a statistically significant difference in VAS (2 months) between US-guided LESI and para-spinal roots and FL-guided LESI and para-spinal roots (P-value = 0.038 and 0.021, respectively). Additionally, there is a statistically significant difference between the US-guided CESI, FL-guided CESI, FL-guided LESI, and spinal nerve roots with respect to ODI (at 2 months). (P-value = 0.033, 0.025 and 0.005, respectively). Conclusion: US is excellent in guiding CESI and LESI and should be the preferred alternative when FL is not provided, with a similar treatment outcome compared to FL-CESI and LESI.

Catheter-Assisted Interlaminar Approach for Cervical Epidural Steroid Injection in Patient with Cervical Stenosis Caused by Ossification of Posterior Longitudinal Ligament: A Case Report

We present the case of a 64-year-old man with cervical ossification of the posterior longitudinal ligament (OPLL) experiencing chronic neck pain and radiculopathy for 6 months. A catheter-assisted interlaminar Cervical Epidural Steroid Injection (CESI) was performed under fluoroscopic guidance, targeting the affected C2-C6 levels. Significant improvement was observed after this procedure, with decreased pain scores (visual analogue scale (VAS) 8 to 2) and improved mobility. This technique not only enhances the effectiveness of CESI but also reduces the likelihood of complications such as stroke or epidural hematoma and thus provides an alternative treatment option for patients with multiple stenotic levels who are unsuitable for surgery or are unresponsive to conservative therapy such as medication or physical therapy.

A Clinical Study in Epidural Injection with Lappaconitine Compound for Post-Operative Analgesia

Objective:The effect and side-effect of epidural injection with lappaconitine compound for post-operative analgesia was observed. Methods: One hundred and twenty patients were randomly divided into 4 groups. Lappaconitine compound (LB) consisted of 12 mg of lappaconitine and 22. 5 mg of bupivacaine, was used for the observed group, and lappaconitine 12 mg, bupivacaine 22. 5 mg and morphine 2 mg for the control group respectively, All were given by epidural injection with single blind method during post-operative pain of incision operation. Results: It was showed that the initiating of analgesia was earlier in LB and bupivacaine group than that in group B and D, and the efficacy was morphine group > LB > bupivacaine > lappaconitine.There was significant difference between group A and B in the above two parameters, P < 0. 01 and P < 0. 05. The analgesia maintenance time of a single injection was morphine > LB > lappaconitine > bupivacaine, that of group D was significantly longer than that of group A (P < 0. 01 ). Conclusions: It indicated that the epidural injection with LB was more rapid and potent than that with lappaconitine alone in post-operative analgesia. Besides, it had no side-effect and safer than morphine.

Outcome of transforaminal epidural steroid injection for lumbar radiculopathy: initial three-year experience at Upendra Devkota Memorial-National Institute of Neurological and Allied Sciences, Nepal

Background:The prevalence of low back pain with radiculopathy in general population varies from 9.9%to 25%,which can be due to bony narrowing of the lateral recess or due to prolapsed intervertebral disc.Transforaminal epidural injection of a mixture of long-acting anaesthetic(bupivacaine)and particulate steroids(depomedrol)has been a treatment modality in patients not responding to initial physiotherapy and neuropathic pain medications.Methods:To analyze the effectiveness of transforaminal epidural steroid injection(TFESI)in the treatment of low back pain with radiculopathy,a retrospective case series evaluating the records of patients that received TFESI(1 mL 0.5%bupivacaine+1 ml/40 mg depomedrol)under C-arm guidance from January 2015 to December 2018(3 years)at Upendra Devkota Memorial-National Institute of Neurological and Allied Sciences(UDM-NINAS),their lumbosacral MRI and the pre-procedure,1-week and 3-month numeric pain rating scale,were analyzed.Successful treatment(reduction of pain scale by more than 50%of baseline at 3 months)in the patients with bony recess stenosis and those with prolapsed intervertebral disc was compared.Results:Out of 67 patients that received TFESI,35(52.23%)could be followed up.The mean age was 55.8±14.39 years and 51.3%were females.68.57%had L5 and 20%had S1 radiculopathy.Bony recess stenosis was seen in the aged 40%and PIVD was the cause of radiculopathy in 60%.The median duration of radicular pain prior to intervention was 3 months.TFESI was effective as the mean numeric pain scale before injection was 8.97±1.32 which reduced to 3.91±3.23(paired t test p value<0.001)at 1 week post injection and 3.23±3.34(paired t test p value<0.001)at 3 months post injection.Twenty-six of the 35 patients(75.29%)had more than 50%pain relief compared to baseline at 3 months and were satisfied.Nine patients continued to have pain;however,only one required a surgical intervention.The effectiveness of TFESI was not significantly different in different ages(Fisher’s exact test p value 0.182)and in different anatomic levels(Fisher’s exact test p value 0.241).Six out of eight patients with bony recess stenosis benefited as compared to 14 out of 19 patients with PIVD,though it was not statistically significant(Fischer’s exact test p value 0.688).There were no adverse events recorded.Conclusion:TFESI is a safe and efficacious treatment modality in patients with radicular low back pain especially in aged patients in whom surgery under general anaesthesia is not free from risk.

Conservative management of spinal pathology with autologous conditioned serum: A systematic review of the literature

BACKGROUND Chronic inflammatory pain is associated with increased expression of interleukin(IL)-1,an inflammatory cytokine,and activity on its receptor(IL-1R).In response,the body produces IL-1R antagonist(IL-1Ra)to reduce this signaling.Autologous conditioned serum(ACS)is the only biologic therapy for spinal pathologies that enhances the action of endogenous IL-1Ra reserves to improve symptoms.This systematic review investigates the effectiveness of ACS in treating pain and dis-ability caused by spinal pathologies.AIM To evaluate the use of ACS as a conservative management option for spinal path-ology.METHODS A systematic review of PubMed/Medline was performed to identify studies inve-stigating administration of ACS for treatment of any spinal pathology.RESULTS Six articles were included,comprising 684 patients treated with epidural(n=133)or transforaminal(n=551)ACS injections.Patients had an average age of 54.0 years with slight female predominance(53.2%).The lumbar spine was most com-monly treated,with 567 patients(82.9%)receiving injections for lumbar radicu-lopathy(n=67),degenerative disc disease(DDD)(n=372),or spinal stenosis(n=128);cervical injections were performed in 109 patients(15.9%).Mean(SD)follow-up was 21.7(4.8)weeks from first ACS injection.All studies investigating mecha-nical lumbar and lumbar or cervical radicular pain reported significant pain re-duction at final follow-up compared to baseline.ACS achieved comparable or su-perior results to lumbar epidural steroid injections.Adverse events were reported in 21 patients(3.1%),with no serious adverse events.CONCLUSION ACS injection is a safe and effective intervention for pain reduction in many spinal pathologies,including cervical and lumbar radiculopathies.
