Abstract
BACKGROUND In recent years, percutaneous kyphoplasty (PKP) has been increasingly used in clinical settings. OBJECTIVE In this study, we aimed to determine the analgesic effect of intravertebral lidocaine injections in PKP. METHODS A total of 60 patients who were treated with PKP were enrolled in this study. Lidocaine hydrochloride was chosen as the medication for the experimental group. Patients were randomly assigned into three groups using a double-blind study design: In group A (20 cases), no drugs were injected into the vertebral body during surgery; group B (20 cases) received intravertebral injection of normal saline; and in group C (20 cases), lidocaine hydrochloride was administered into the vertebral body during surgery. The age of patients, operation time, balloon dilatation pressure, balloon dilatation volume, and amount of bone cement injected were compared across the three groups. A pain visual analog scale (VAS) was used to assess pain suffered by the patients before, during, and 24 hours after the surgery. RESULTS Age, operation time, balloon dilatation pressure, balloon dilatation volume, and amount of bone cement injected did not differ significantly among the three groups (P> 0.05). The differences in VAS scores 24 hours before and after surgery were not statistically significant (P> 0.05). Group C had lower intraoperative VAS scores than groups A and B, and the difference was statistically significant (P< 0.01). There was no statistically significant difference between group A and group B (P> 0.05). CONCLUSION Intravertebral injections of lidocaine during PKP can successfully reduce intraoperative pain.

Abstract
BACKGROUND Kyphoplasty for osteoporotic vertebral compression fractures (OVCF) is a short but painful intervention. Different anesthetic techniques have been proposed to control pain during kyphoplasty; however, all have limitations. OBJECTIVE To compare the effectiveness and safety of ultrasound-guided thoracic paravertebral block with local anesthesia for percutaneous kyphoplasty (PKP). METHODS In this prospective study, non-randomized patients with OVCF undergoing PKP received either ultrasound-guided thoracic paravertebral block (group P) or local anesthesia (group L). Perioperative pain, satisfaction with anesthesia, and complications were compared between the groups. RESULTS Mean intraoperative (T1-T4) perioperative visual analog scale (VAS) scores were significantly lower in group P than in group L (2 [1-3] vs. 3 [2-4], 2 [2-3] vs. 4 [2-4], 2 [2-3] vs. 5 [3-5], and 3 [2-3] vs. 5 [3-5], respectively; P< 0.05). Investigators' satisfaction scores, patients' anesthesia satisfaction scores, and anesthesia re-administration intention rate were significantly higher in group P than in group L (4 [3-5] vs. 3 [2-4], 2 [2-3] vs. 2 [1-3], 90.63% vs. 69.70%; P< 0.05). There was no significant intergroup difference in complications. CONCLUSIONS Ultrasound-guided thoracic paravertebral block has similar safety to and better effectiveness than local anesthesia in PKP.

Efficacy of intraoperative sedation combined with preemptive analgesia for single-level kyphoplasty under local anesthesia: A randomized clinical trial. J Orthop Sci 2022; 27:1215-1221. [PMID: 34756518 DOI: 10.1016/j.jos.2021.08.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 08/19/2021] [Accepted: 08/23/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Kyphoplasty is widely used for Osteoporotic Vertebral Compression Fracture (OVCF) under general or local anesthesia, more attention was paid to its post-operative efficacy. Patients' pain and discomfort control strategies during surgery have not been taken seriously. OBJECTIVE This study aimed at assessing the efficacy of preoperative preemptive analgesia combined with intraoperative sedation for pain and tension relief in OVCF patients undergoing kyphoplasty under local anesthesia. METHODS We enrolled 128 patients with single-level OVCF who underwent kyphoplasty in our hospital from July 2013 to July 2016. The patients were randomly allocated into three groups: conventional group (i.e., local anesthesia with 0.5% lidocaine (1); n = 42), preemptive group (i.e, (1) + oral 200 mg Celecoxib on the night before surgery with intravenous 40 mg parecoxib sodium an hour before surgery (2); n = 43), and combined group (i.e., (1) + (2) + continuous intravenous 0.5 μg/kg/h dexmedetomidine intraoperatively; n = 43). Hemodynamic variations (heart rate, blood pressure, pulse oxygen saturation (SpO2)), Pain Visual Analogue Score (VAS), Ramsay score, and adverse events were recorded during perioperative period. RESULTS Blood pressure and heart rate were more stable with significantly smaller values in the combined group than in the conventional and preemptive groups both intra- and postoperatively. In contrast, SpO2 showed no significant difference among the groups throughout the perioperative period. Intraoperative VAS scores revealed significant differences among the groups with the combined group having the smallest values followed by the preemptive group. Similarly, intraoperative Ramsay scores reflected significantly more favorable effects of sedation in the combined than in conventional group. Both VAS and Ramsay scores showed no significant differences among the groups postoperatively, and no differences in complication incidences were noted among the groups as well. CONCLUSIONS For kyphoplasty under local anesthesia for single-level OVCF, intraoperative sedation combined with preemptive analgesia worked better in mitigating pain and tension intraoperatively and in preventing hemodynamic changes intra- and post-operatively, as compared to local anesthesia alone or additional preemptive analgesia.

Abstract
Objective Percutaneous kyphoplasty (PKP) is an effective minimally invasive technique in spine surgery in recent years. General anesthesia and local anesthesia are the main ways of anesthesia in PKP, and epidural anesthesia is also applied to PKP to some extent. However, all these three anesthetic methods have their respective advantages and disadvantages. It is essential to compare and evaluate the effects of different anesthesia methods on PKP for treating spinal fractures. Method A total of 45 patients (53 vertebral bodies were included) were divided into two groups. Group A included 24 patients (29 vertebral bodies) with an average of 71 years old and Group B included 21 patients (24 vertebral bodies) with an average of 74 years old. Visual analogue scale (VAS) scores were recorded preoperatively; balloon expansion and bone cement injection were conducted intraoperatively. Then, they were recorded immediately after operation, 6 h postoperatively, to assess the pain level of the patient. Moreover, hospitalization time (days), operation duration (minutes), and bone cement injection amount (mL) had also been recorded. Results There was no significant difference in preoperative general information and VAS score. However, the VAS scores were statistically significant at both the moment of balloon expansion and injection of bone cement. At the moment of immediate postoperation, the VAS scores showed no statistically significant difference, while it showed a statistically significant difference 6 h postoperatively. Conclusion The anesthesia method by injection of 1% lidocaine hydrochloride (5 ml) into vertebral body can effectively relieve patients' pain in intraoperation and postoperation.

Abstract
Objective To evaluate the analgesic effect of vertebral cancellous bone infiltration anaesthesia during percutaneous vertebroplasty (PVP). Methods Patients treated with vertebral cancellous bone infiltration anaesthesia (intervention group) or local anaesthesia alone (control group) during PVP at our institution during 2016–2018 were reviewed. The visual analogue scale (VAS) score before the operation, during establishment of the puncture channel, during pressure changes in the vertebral body (e.g., when removing or inserting pushers or needle cores), during bone cement injection, immediately after the operation, and at 2 h and 1 day postoperatively were compared between the groups. The patient’s satisfaction with the operation was recorded and compared between groups. Results A total of 112 patients were enrolled (59 cases in the intervention group and 53 cases in the control group). There was no difference in the VAS score between the groups before the operation or during establishment of the intraoperative puncture channel (P > 0.05). The VAS score in the intervention group was significantly lower than that in the control group during pressure changes in the vertebral body (removal or insertion of puncture needle cores or pushers) and bone cement injection (P < 0.05). Immediately after the operation and at 2 h postoperatively, the pain in the intervention group was also significantly lower than that in the control group (P < 0.05), but there was no significant difference between the groups at 1 day postoperatively (P > 0.05). The patient satisfaction rate was 88% (52/59) in the intervention group and 67% (35/53) in the control group (P < 0.05). Conclusions Vertebral cancellous bone infiltration anaesthesia may effectively relieve intraoperative pain and improve the surgical experience of patients without affecting the clinical effect of surgery.

Abstract
In this study, we explored the release characteristics of analgesics, namely levobupivacaine, lidocaine, and acemetacin, from electrosprayed poly(D,L-lactide-co-glycolide) (PLGA) microparticles. The drug-loaded particles were prepared using electrospraying techniques and evaluated for their morphology, drug release kinetics, and pain relief activity. The morphology of the produced microparticles elucidated by scanning electron microscopy revealed that the optimal parameters for electrospraying were 9 kV, 1 mL/h, and 10 cm for voltage, flow rate, and travel distance, respectively. Fourier-transform infrared spectrometry indicated that the analgesics had been successfully incorporated into the PLGA microparticles. The analgesic-loaded microparticles possessed low toxicity against human fibroblasts and were able to sustainably elute levobupivacaine, lidocaine, and acemetacin in vitro. Furthermore, electrosprayed microparticles were found to release high levels of lidocaine and acemetacin (well over the minimum therapeutic concentrations) and levobupivacaine at the fracture site of rats for more than 28 days and 12 days, respectively. Analgesic-loaded microparticles demonstrated their effectiveness and sustained performance for pain relief in fracture injuries.

Abstract
STUDY DESIGN A prospective randomized cohort study. OBJECTIVE The objective of this study was to investigate the effect of intraoperative vertebral anesthesia on osteoporotic vertebral compression fractures (OVCFs) when treated with percutaneous kyphoplasty (PKP). SUMMARY OF BACKGROUND DATA Only a few studies have evaluated the intraoperative pain reducing strategies during PKP. MATERIALS AND METHODS A total of 64 patients with OVCFs were enrolled in the study. All of the patients were randomized into 2 groups: the traditional local anesthesia group (from the skin to the periosteum, group A) and the experimental group (from the skin to a vertebral body, group B). Visual Analogue Scale (VAS) score was used to evaluate the degree of pain at six time points, that is, VAS before surgery, VAS during balloon dilation, VAS during bone cement injection, VAS soon after surgery, and VAS 12 hours and 24 hours after surgery. In addition, we noted the patients' willingness to undergo reoperation if necessary, and the variations in surgical complications between the 2 groups. RESULTS There was no significant difference in VAS score before surgery between the 2 groups (t=1.694, P=0.095). The VAS scores during balloon dilatation, bone cement injection and soon after surgery were significantly different between the 2 groups (t=4.405, P=0.000; t=2.481, P=0.016; t=2.992, P=0.004, respectively). The willingness to undergo reoperation was significantly different between 2 groups (χ=6.020, P=0.049), whereas the complications showed no significant difference (χ=0.000, P=0.754). CONCLUSIONS Traditional local anesthesia combined with vertebral anesthesia was effective in alleviating perioperative pain during PKP. No serious complication was noted during the operation. LEVEL OF EVIDENCE Level I.

Abstract
Background The proper choice of anesthesia for kyphoplasty remains controversy. There are only a few clinical studies specially focusing on and giving detailed information about this treatment under local anesthesia with or without conscious sedation. To evaluate the effect of preoperative prone position exercises on patient tolerance to percutaneous kyphoplasty under local anesthesia. Methods Eighty-three patients with single level osteoporotic vertebral compression fractures were nonrandomly assigned to undergo percutaneous kyphoplasty under local anesthesia with preoperative prone position exercises or without. The number of procedure with or without a pause, need for intravenous sedation, and patient satisfactory were recorded and analyzed. Clinical outcomes were assessed using the visual analog scale and the Oswestry Disability Index. The follow-up time was 6 months. Results The baseline characteristics of both groups were comparable. The number of procedure without a pause in the exercises group was more than the control group (30/42 patients and 10/41 patients, respectively, P < 0.001), and fewer patients required intravenous sedation in the exercises group (7/42 and 28/41, respectively, P < 0.001). Patients in the exercises group were more satisfied compared to the control group (41/42 and 32/41, respectively, P < 0.01). There were no significant differences between the two groups with regard to improvement in pain and functional scores at all postoperative intervals. Conclusions Prone position exercises may improve patient tolerance and satisfaction and reduce the need for intravenous sedation for those with single level vertebral compression fracture undergoing kyphoplasty under local anesthesia. We expect large sample size and multi-center randomized controlled trial studies to be conducted.

Abstract
Aim. This report introduces extrapedicular infiltration anesthesia as an improved method of local anesthesia for unipedicular percutaneous vertebroplasty or percutaneous kyphoplasty. Method. From March 2015 to March 2016, 44 patients (11 males and 33 females) with osteoporotic vertebral compression fractures with a mean age of 71.4 ± 8.8 years (range: 60 to 89) received percutaneous vertebroplasty or percutaneous kyphoplasty. 24 patients were managed with conventional local infiltration anesthesia (CLIA) and 20 patients with both CLIA and extrapedicular infiltration anesthesia (EPIA). Patients evaluated intraoperative pain by means of the visual analogue score and were monitored during the procedure for additional sedative analgesia needs and for adverse nerve root effects. Results. VAS of CLIA + EPIA and CLIA group was 2.5 ± 0.7 and 4.3 ± 1.0, respectively, and there was significant difference (P = 0.001). In CLIA group, 1 patient required additional sedative analgesia, but in CLIA + EPIA group, no patients required that. In the two groups, no adverse nerve root effects were noted. Summary. Extrapedicular infiltration anesthesia provided good local anesthetic effects without significant complications. This method deserves further consideration for use in unipedicular percutaneous vertebroplasty and percutaneous kyphoplasty.

Abstract
BACKGROUND Since bone marrow receives innervation from A-delta and C-fibers and since an increase in intramedullary pressure in bone marrow may induce acute pain in orthopedic patients during surgery and chronic pain in patients with bone marrow edema, skeletal pain may partly originate from bone marrow. Intraosseous lesions, such as osteomyelitis and bone cancer, are also known to produce cutaneous hypersensitivity, which might be referred pain from bone. However, little is known about pain perception in bone marrow and referred pain induced by bone disease. Thus, we carried out an in vivo electrophysiological study and behavioral study to determine whether increased intraosseous pressure of the femur induces acute pain and whether increased intraosseous pressure induces referred pain in the corresponding receptive fields of the skin. RESULTS Intraosseous balloon inflation caused spontaneous pain-related behavior and mechanical hyperalgesia and allodynia in the lumbosacral region. Single neuronal activities of spinal dorsal horn neurons were extracellularly isolated, and then evoked responses to non-noxious and noxious cutaneous stimuli and intraosseous balloon inflation were recorded. Ninety-four spinal dorsal horn neurons, which had somatic receptive fields at the lower back and thigh, were obtained. Sixty-two percent of the wide-dynamic-range neurons (24/39) and 86% of the high-threshold neurons (12/14) responded to intraosseous balloon inflation, while none of the low-threshold neurons (0/41) responded to intraosseous balloon inflation. Spinally administered morphine (1 µg) abolished balloon inflation-induced spontaneous pain-related behavior and mechanical hyperalgesia in awake rats and also suppressed evoked activities of wide-dynamic-range neurons to noxious cutaneous stimulation and intraosseous balloon inflation. CONCLUSIONS The results suggest that mechanical stimulation to bone marrow produces nociception, concomitantly producing its referred pain in the corresponding skin fields. These mechanisms might contribute to pain caused by skeletal diseases.

Abstract
Aim. This report introduces extrapedicular infiltration anesthesia as an improved method of local anesthesia for unipedicular percutaneous vertebroplasty or percutaneous kyphoplasty. Method. From March 2015 to March 2016, 44 patients (11 males and 33 females) with osteoporotic vertebral compression fractures with a mean age of 71.4 ± 8.8 years (range: 60 to 89) received percutaneous vertebroplasty or percutaneous kyphoplasty. 24 patients were managed with conventional local infiltration anesthesia (CLIA) and 20 patients with both CLIA and extrapedicular infiltration anesthesia (EPIA). Patients evaluated intraoperative pain by means of the visual analogue score and were monitored during the procedure for additional sedative analgesia needs and for adverse nerve root effects. Results. VAS of CLIA + EPIA and CLIA group was 2.5 ± 0.7 and 4.3 ± 1.0, respectively, and there was significant difference (P = 0.001). In CLIA group, 1 patient required additional sedative analgesia, but in CLIA + EPIA group, no patients required that. In the two groups, no adverse nerve root effects were noted. Summary. Extrapedicular infiltration anesthesia provided good local anesthetic effects without significant complications. This method deserves further consideration for use in unipedicular percutaneous vertebroplasty and percutaneous kyphoplasty.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2010; 19:1913-20.

Abstract
Clinically, the displacement of intravertebral fat into the circulation during vertebroplasty is reported to lead to problems in elderly patients and can represent a serious complication, especially when multiple levels have to be treated. An in vitro study has shown the feasibility of removing intravertebral fat by pulsed jet-lavage prior to vertebroplasty, potentially reducing the embolization of bone marrow fat from the vertebral bodies and alleviating the cardiovascular changes elicited by pulmonary fat embolism. In this in vivo study, percutaneous vertebroplasty using polymethylmethacrylate (PMMA) was performed in three lumbar vertebrae of 11 sheep. In six sheep (lavage group), pulsed jet-lavage was performed prior to injection of PMMA compared to the control group of five sheep receiving only PMMA vertebroplasty. Invasive recording of blood pressures was performed continuously until 60 min after the last injection. Cardiac output and arterial blood gas parameters were measured at selected time points. Post mortem, the injected cement volume was measured using CT and lung biopsies were processed for assessment of intravascular fat. Pulsed jet-lavage was feasible in the in vivo setting. In the control group, the injection of PMMA resulted in pulmonary fat embolism and a sudden and significant increase in mean pulmonary arterial pressure. Pulsed jet-lavage prevented any cardiovascular changes and significantly reduced the severity of bone marrow fat embolization. Even though significantly more cement had been injected into the lavaged vertebral bodies, significantly fewer intravascular fat emboli were identified in the lung tissue. Pulsed jet-lavage prevented the cardiovascular complications after PMMA vertebroplasty in sheep and alleviated the severity of pulmonary fat embolism.

Abstract
Over the last few years bone resin based vertebral augmentation in the form of vertebro- and kyphoplasty has proved to be a safe therapeutic option in cases of vertebral compression fractures. Nevertheless, rare systemic complications have been seen, i.e., pulmonary embolisms ranging from harmless to lethal.The presence of an anesthesiologist can be especially useful in cases of systemic complications. Whether the form of anesthesia has any influence on the outcome of vertebro- or kyphoplasty is currently unknown. Local anesthesia supplemented by analgosedation is often used as an alternative to general anesthesia. The rationale for one or the other form of anesthesia can be factors like type of augmentation (vertebro- or kyphoplasty), number of vertebral levels to be treated as well as the patient's age, condition, and comorbidities.Single-shot epidural anesthesia is yet another anesthetic option that has been successfully used in our clinic for some years now. It combines the advantages of general and local anesthesia: excellent segmental analgesia even in multilevel cases in awake and responding patients.

Abstract
UNLABELLED Percutaneous vertebroplasty (PVP) consists of injecting small quantities of orthopedic cement to consolidate pathologic vertebral bodies. The procedure is brief but painful during vertebral puncture and cement injection requiring either general anesthesia or monitored anesthesia care with opioids. The optimal dose of alfentanil in this setting is unknown. Therefore, we sought to determine its median effective dose (ED50, or analgesic efficacy in 50% of patients) during PVP in none intubated, spontaneously breathing patients. After approval and informed consent of the Institutional Review Board, 50 patients (American Society of Anesthesiologists II-III, age 50 to 80, weight: 53 to 82 kg) with osteoporotic vertebral fractures were enrolled. The patients were premedicated with oral hydroxyzine 100 mg and had skin infiltration with 50 mg lidocaine before vertebral puncture. The prone position was adopted and oxygen was provided via a facemask. Noninvasive cardiorespiratory variables were monitored. Pain was evaluated by a numerical pain scale (NPS) where 0 represents no pain and 10 the worst tolerable pain. Alfentanil infusion was started 30 minutes before vertebral puncture. The initial dose was 2.0 mg/h. Thereafter, a 0.05 mg/h decrease or increase was applied to the next patient if analgesia was effective (NPS: 3 or less) or not (NPS>3) according to the Dixon method. The bootstrap resampling technique was used to calculate the ED50 and its 95% confidence limits. The latter was 1.05 mg/h (95% confidence interval, 1.0-1.2). Transient apnea (n=2) and nausea/vomiting (n=3) were observed. Given the median body weight of the patients (65 kg), we conclude that 0.27 microg kg/min of alfentanil provides effective analgesia for PVP under monitored anesthesia care. SUMMARY STATEMENT PVP consists of injecting small quantities of orthopedic cement to consolidate pathologic vertebral bodies. The median effective dose (ED50) for pain relief during vertebral puncture and cement injection is 1.05 (95% confidence interval, 1.0-1.2) mg/h when infusion is started 30 minutes before the procedure. Given the median body weight of our study population (65 kg), this dose corresponds to 0.27 microg kg/min.

Abstract
BACKGROUND Intraoperative cardiovascular deterioration as a result of pulmonary embolization of bone marrow fat is a potentially serious complication during vertebroplasty. The release of fatty material and thromboplastin from the bone marrow cavity during vertebroplasty may activate the coagulation cascade resulting in thrombogenesis, and pharmacological prophylaxis may therefore prevent cardiovascular complications. Thus, the effects of bone marrow fat embolism on coagulation activation during vertebroplasty were investigated with use of an animal model. METHODS Polymethylmethacrylate was injected into three lumbar vertebrae of six sheep in order to force bone marrow fat into the circulation. Invasive blood pressures and heart rate were recorded continuously until sixty minutes after the last injection. Cardiac output, arterial and mixed venous blood gas parameters, and coagulation parameters were measured at selected time-points. Postmortem lung biopsy specimens were assessed for the presence of intravascular fat. RESULTS Embolization of bone marrow fat resulted in a sudden and dramatic increase in mean pulmonary arterial pressure and a decrease in mean arterial blood pressure. There were no significant changes in any coagulation parameter from before the injection to after the injection. Intravascular fat and bone marrow cells were present in all lung lobes. CONCLUSIONS Injection of polymethylmethacrylate into vertebral bodies caused embolization of bone marrow fat with subsequent transient cardiovascular deterioration, but no changes in coagulation parameters were observed. Thromboembolism did not contribute to the observed cardiovascular changes.

Abstract
OBJECTIVE To describe the new procedures applied for interventional radiology leading to specific anaesthetic care and organization. DATA SOURCE Record of references from national and international journals in Medline. STUDY SELECTION All types of articles were selected including prospective studies, practice guidelines, reviews and case reports. DATA SYNTHESIS During interventional radiology, anaesthesia should be adapted to the duration of the procedure, the pain induced by the radiologist, the position of the patient and its medical status. General anaesthesia would be preferred for long procedures, requiring total immobility. Locoregional anaesthesia can be proposed for some cases. Sedation associating hypnotics (propofol, midazolam, sevoflurane) and opioids (alfentanil, remifentanil) is commonly used according to different schemes, as discontinuous boluses, continuous infusion, target controlled intravenous sedation or patient controlled sedation. Monitoring of temperature and diuresis may be useful for long procedures. Haemodynamic monitoring (arterial catheter, central venous pressure) and haemostatic monitoring may be necessary for interventional neuroradiology and endovascular stenting. Radiofrequency and laser procedures are often painful, requiring the choice of adequate analgesic regimen. Hydratation associated with acetylcysteine seems to be able to prevent contrast induced nephropathy in patients with risk factors for chronic renal insufficiency. CONCLUSION As advances in interventional radiology are obvious, general organisation as well as anaesthetic procedures should be adapted to these specific techniques.

Abstract
Percutaneous vertebroplasty has now been in use in the United States for 10 years. Standards of practice are available from the American College of Radiology. The performance of this procedure is becoming routine for most interventional practices, and it has become the general standard of care for pain associated with vertebral compression fractures of the spine. This article describes routine procedural technique and considerations and is intended to review the authors' knowledge of the procedure and provide reliable methods for good outcomes and complication avoidance.
