Bio


Dr. Ottestad joined Stanford faculty in 2007 and became Director of the Acute Pain Service in 2009. As such, he manages acute, post-operative pain, acute-on-chronic inpatient pain consults, and cancer pain at Stanford Hospital. He is committed to the Stanford Pain Center’s multidisciplinary, comprehensive approach when treating pain clinic patients with chronic pain. In the outpatient pain clinic, Dr. Ottestad possesses expertise in advanced interventions such as intrathecal medications, spinal cord stimulation, peripheral nerve stimulation, cryotherapy and cryoanalgesia, radiofrequency neuromodulation and ablation and ultrasound-guided procedures in general for the treatment of chronic pain. Ultrasound imaging allows accurate imaging of soft tissues such as muscles, tendons, and nerves that are difficult to identify using only x-ray imaging or anatomic landmarks. This imaging is useful both diagnostically as well as therapeutically when specific, targeted treatment is needed in an area of pain.

Dr. Ottestad has written multiple book chapters and papers on pain management and has been an invited lecturer and instructor for over 60 national and international conferences in the last 8 years. He will become the President of World Academy of Pain Medicine Ultrasonography (WAPMU) in 2017. Dr. Ottestad is board certified in anesthesiology and pain management, and is an also an instructor and board examiner for the World Institute of Pain and the World Academy of Pain Medicine Ultrasonography, with secondary international qualifications FIPP (Fellow of Interventional Pain Practice) and CIPS (Certification in Pain Medicine Sonology).

Clinical Trials


  • Using Peripheral Nerve Stimulation (PNS) to Treat Chronic Post-surgical Pain (CPSP) After Knee Surgery Not Recruiting

    SPRINT PNS System will be offered to patients with postoperative knee pain following primary unilateral total knee arthroplasty (TKA) who meet eligibility criteria and consistent with established coverage policy. SPRINT PNS System will be implanted for 60 days. At the discretion of the physician, the first lead may be placed to stimulate the nerve innervating the region of greatest pain. If pain is not adequately addressed by the first lead when assessed at 10 days, a second lead may be placed approximately 2 weeks following the initial lead placement.

    Stanford is currently not accepting patients for this trial.

    Abstract

    Injury to saphenous nerve branches is frequent during knee surgery and can result in chronic pain. This saphenous neuralgia remains challenging to treat. Peripheral nerve stimulation (PNS) is a new potential non-pharmacologic treatment option. We present our outcomes experience using this technology in 12 patients.We retrospectively reviewed PNS placement for saphenous neuralgia between 2000 and 2022 at a single institution. Demographic information was collected as well as response to the device. Four-question short-form Patient-Reported Outcome Measurement Information System (PROMIS) Scores were collected before and 2 weeks, 6 weeks, and 6 months postprocedure. Specific scores included pain interference and behavior, functional mobility, depression, anxiety, and sleep impairment. Change in pain interference measured by the short-form PROMIS tool at 6 months was chosen as the primary outcome.Twelve patients met inclusion criteria, with 10 patients having the full 6-month follow-up. In these 10 patients, the mean change from baseline in the short-form adjusted pain interference score (greater difference means improved pain) at 6 months was 5.8 (SD 6.5). Among all patients, average follow-up was 11.5 months (range 3-35 months). Most patients' symptoms developed after knee surgery (84%). Prior to PNS, patients underwent other treatments including cryoablation (8%), radiofrequency ablation (16%), saphenous neurectomy (16%), or surgical release of adjacent nerves (25%). Ten patients (83%) reported any improvement in symptoms while two reported no benefit. Complications occurred in four patients (33%). Two patients had the device removed and a third discontinued use. PROMIS Scores for pain, functional mobility, mood, and sleep impairment all improved.Limited effective treatments exist for saphenous neuralgia. Our case series demonstrates the potential of PNS as a treatment for saphenous neuralgia. Comparative effectiveness studies are warranted to assess whether our effect size is clinically relevant.

  • Role of peripheral nerve stimulation in treating chronic neuropathic pain: an international focused survey of pain medicine experts. Regional anesthesia and pain medicine Li, A. H., Bhatia, A., Gulati, A., Ottestad, E. 2023; 48 (6): 312-318

    Abstract

    Interventional pain management (IPM) options for refractory neuropathic pain (NP) have recently increased with availability of peripheral nerve stimulation (PNS) equipment and expertise. Given a lack of high-quality evidence and guidelines on this topic, we sought to understand the perception of physicians with expertise in treating NP regarding IPM and the role of PNS. We emailed a survey in March 2022 to international NP experts including pain medicine physicians, researchers, and leaders of 11 professional pain societies. No representatives from vendors of PNS systems were included in the design of the survey nor as respondents. Among 24 respondents (67% of those contacted), the distal common peroneal, tibial, and sural nerves were most frequently targeted (60%) with PNS. Persistent postsurgical pain of more than 3 months was the most common indication for PNS (84%). The aggregate NP treatment algorithm in order of median rank was non-opioid medications as first line, IPM including epidural/perineural steroid injections tied with transcutaneous electrical nerve stimulation as second line, pulsed radiofrequency (RF) tied with RF ablation/denervation as third line, temporary then permanent PNS as fourth line, followed by spinal cord stimulation, opioids, cryoablation, botulinum, peripheral nerve field stimulation, intrathecal targeted drug delivery, and others. Before offering PNS, 12 respondents (50%) indicated their preference for trialing non-neuromodulation treatments for 1-3 months. Twenty-two respondents (92%) agreed PNS should be offered early in the treatment of neuropathic pain. The most common barriers to PNS use were cost, lack of high-quality evidence in support of its use, lack of exposure to PNS in training programs, and lack of familiarity with the use of ultrasound guidance. PNS appears to have an increasing role in the treatment of NP but more research is needed on the outcomes of PNS to elucidate its role.

    Abstract

    Chronic postsurgical pain (CPSP), also known as persistent postsurgical pain (PPSP), is pain that develops or increases in intensity after a surgical procedure and lasts more than 3 months. Transitional pain medicine is the medical field that focuses on understanding the mechanisms of CPSP and defining risk factors and developing preventive treatments. Unfortunately, one significant challenge is the risk of developing opioid use dependence. Multiple risk factors have been discovered, with the most common, and modifiable, being uncontrolled acute postoperative pain; preoperative anxiety and depression; and preoperative site pain, chronic pain, and opioid use.

  • Clinical Approach to Chronic Pain due to Perioperative Nerve Injury. Anesthesiology clinics Terkawi, A. S., Altirkawi, O. K., Salmasi, V., Ottestad, E. 2023; 41 (2): 489-502

    Abstract

    Perioperative nerve injuries are common and may be prevented. The estimated incidence of perioperative nerve injury is 10% to 50%. However, most of these injuries are minor and self-recovering. Severe injuries account for up to 10%. Potential mechanisms of injury are nerve stretch, compression, hypoperfusion, direct nerve trauma, or injury during vessel cannulation. Nerve injury pain usually presents as neuropathic pain ranging from mild to severe mononeuropathy and extends to the disabling complex regional pain syndrome. This review provides a clinical approach to subacute and chronic pain secondary to perioperative nerve injury, presentation, and management.

  • Application of multidisciplinary team conference for neuromodulation candidates facilitates patient selection and optimization. Frontiers in pain research (Lausanne, Switzerland) Salmasi, V., Rasouli, M. R., Kao, M. C., Ottestad, E., Terkawi, A. S., Morris, G., Qian, X., Coleman, S., Talavera, D. C., Poupore-King, H., Slater, K., Leong, M. S. 2023; 4: 1331883

    Abstract

    Psychological evaluation is required by insurance companies in the United States prior to proceeding with a spinal cord stimulation or a dorsal root ganglion stimulation trial. Since January 2017, we implemented a Multidisciplinary Team Conference for Neuromodulation in our center to facilitate the collaboration between pain physicians and psychologists and to optimize screening of neuromodulation candidates. This study aims to report the impact of this team conference on improvement of neuromodulation outcome in our center.Appropriateness of neuromodulation were discussed in the team conference after initial visit with the pain specialist and psychological evaluation. For this study, we prospectively and retrospectively collected data on neuromodulation candidates who went through the team conference and those who did not as controls.We discussed 461 patients in the team conference sessions from January 2017 to July 2023. Out of these, a spinal cord stimulator or a dorsal root ganglion stimulator trial was performed in 164 patients with 80.5% (132 cases) trial success rate leading to 140 implants. Out of these implants, 26 (18.6%) explanted and 21 (15%) required revision in 41 (29.3%) patients. We performed neuraxial neuromodulation trial for 70 patients without going through the team conference from January 2016 to July 2023 with a trial success rate of 45.7% (32 cases). In this group, 7 (21.9%) and 6 (18.8%) patients underwent explant and revision. The differences between the groups were statistically significant for trial success rate (odds ratio of 4.9 with p-value of <0.01) but not for explant (odds ratio of 0.8 with p-value of 0.627) or revision (odds ratio of 0.8 with p-value of 0.595).Implementing Multidisciplinary Team Conference increased trial success rate in our center. Team conference provides therapeutic benefit for patients, and also provides the opportunity for an educational discussion for trainees.

  • Assessment of outcomes in consecutive patients undergoing dorsal scapular nerve decompression. Journal of neurosurgery Ottestad, E., Wilson, T. J. 2022: 1-8

    Abstract

    OBJECTIVE: Periscapular pain has a broad differential diagnosis. Dorsal scapular neuropathy is part of that differential diagnosis but is often forgotten by clinicians, leading to delayed diagnosis, chronic pain, and potentially worse outcomes. The objective of this study was to describe our method for diagnosis, surgical technique, intraoperative findings, and outcomes in consecutive patients undergoing dorsal scapular nerve (DSN) decompression.METHODS: A retrospective cohort study was performed to compile and describe outcomes for consecutive patients (n = 21) who underwent DSN decompression by a single surgeon during the period between August 2018 and February 2021. The primary outcome was change in visual analog scale (VAS) score for periscapular pain between baseline and 6 months postoperatively. Secondary outcomes included change in VAS score for overall pain, change in Disabilities of the Arm, Shoulder, and Hand (DASH) score, and change in the Zung Self-Rating Depression Scale (Zung SDS) between baseline and 6 and 12 months postoperatively.RESULTS: Patients undergoing DSN decompression showed significant improvement in VAS score for periscapular pain between baseline and 6 months postoperatively (mean score 54.0 vs 26.8, respectively; p < 0.001). Fifteen of 21 patients (71%) had a good outcome (score improvement ≥ 20). Disability (as determined by DASH scores) was significantly improved at 6 and 12 months postoperatively. The only factor that was predictive of outcome was symptom duration, with longer symptom duration predicting a poor outcome.CONCLUSIONS: Surgical treatment of dorsal scapular neuropathy is associated with significant improvements in pain and disability, and these improvements are durable. Morbidity associated with surgical treatment is low.

  • Application of the novel Nalu Neurostimulation System for peripheral nerve stimulation. Pain management Kalia, H., Pritzlaff, S., Li, A. H., Ottestad, E., Gulati, A., Makous, J., Chakravarthy, K. 2022

    Abstract

    Peripheral nerve stimulation is an established treatment modality for chronic neuropathic pain. Over the last decade, with the advent of innovative devices and delivery platforms, peripheral nerve stimulation has evolved from invasive open surgeries to image-guided, minimally invasive percutaneous procedures. The authors hereby present a novel device, the Nalu Neurostimulation System(Nalu Medical, CA, USA), which has established its advantages in providing predictable and reliable peripheral nerve stimulation therapy for chronic neuropathic pain management. This novel device is effective in treating chronic pain conditions such as post-herniorrhaphy pain syndrome, intercostal neuralgia, post-laminectomy syndrome, and complex regional pain syndromeand holds great promise for the treatment of peripheral neuropathic pain.

  • Considerations in Permanent Implantation of Peripheral Nerve Stimulation (PNS) for Chronic Neuropathic Pain: An International Cross Sectional Survey of Implanters. Pain practice : the official journal of World Institute of Pain Li, A. H., Gulati, A., Leong, M. S., Aggarwal, A. K., Salmasi, V., Spinner, D., Ottestad, E. 2022

    Abstract

    INTRODUCTION: Novel minimally invasive short-term and long-term peripheral nerve stimulation (PNS) systems have revolutionized targeted treatment of chronic neuropathic pain. We present an international survey of PNS-implanting pain physicians to assess what factors they consider when offering permanent PNS.METHODS: This cross-sectional study consisted of a survey (Qualtrics) that was distributed to PNS-implanting physicians in a device supplier's entire email database on November 13, 2020, with 3 weeks of response time. Physicians' contact information in the form of their email addresses had been previously collected by the supplier upon device distribution with permission to use survey responses for research.RESULTS: Of 2,032 database physicians, 40 physicians representing 37 institutions responded to the survey. The most common application of PNS was mononeuropathic pain (57%). The most frequently targeted nerve was the suprascapular nerve (29%). 14% of physicians reported 81-100% of their implants were dual-lead. The representative physicians ranged broadly in their most frequently-targeted nerves. Although mononeuropathic pain was the most common indication for PNS, there was still varied response regarding other indications such as CRPS and post-surgical chronic pain.CONCLUSION: In context of a low response rate, identifying such factors can help update the prevailing treatment algorithm for interventional therapies, assist pain physicians in better identifying which patients are the best candidates for PNS, and inform future clinical trial design on PNS efficacy.

  • Understanding the role of patient preference in the treatment algorithm for chronic low back pain: results from a survey-based study. Pain management Staats, P., Deer, T., Ottestad, E., Erdek, M., Spinner, D., Gulati, A. 2021

    Abstract

    Aims: Interventional pain treatments range from injections to established radiofrequency ablation techniques and finally neuromodulation. In addition to safety, efficacyand cost dominance, patient preference for type of treatment is important. Methods: Chronic pain patients (n=129) completed a preference scale to determine which interventional pain management procedures they would prefer from among radiofrequency ablation, temporary (60-day) peripheral nerve stimulation (PNS), conventional PNS and spinal cord stimulation/dorsal root ganglion stimulation. A second survey (n=347) specific to assessing the preference for radiofrequency ablation or temporary PNS treatment was completed by patients with low back pain. Results: On the basis of mean rank, temporary PNS percutaneously implanted for up to 60days was the most preferred treatment compared with the other options presented (p=0.002). Conclusions: Patient preference should be unbiased and considered as an independent variable for physician discussion in treatment options and future research.

  • Peripheral Nerve Stimulation for Occipital Neuralgia. Pain medicine (Malden, Mass.) Salmasi, V., Olatoye, O. O., Terkawi, A. S., Hah, J. M., Ottestad, E., Pingree, M. 2020; 21 (Supplement_1): S13–S17

    Abstract

    BACKGROUND: Chronic headaches are the second most prevalent disease and second most common cause for years lived with disability worldwide. Occipital neuralgia can cause headaches or be present in addition to other more prevalent causes of headache. If these headaches fail to respond to conservative and pharmacological therapy, physicians proceed to more invasive treatments, starting with infiltration of the greater occipital nerve with local anesthetic with or without corticosteroids, followed by nerve ablation or stimulation. Occipital nerve stimulation gained more popularity as the technology improved and more pain physicians received training on interventional procedures.METHODS: In this manuscript, we are presenting our experience with ultrasound-guided implant of occipital nerve stimulators using peripheral nerve stimulator systems. After confirming appropriateness of treatment by a successful occipital nerve block (i.e., resulting in >50% relief in patients' pain intensity), we implanted five stimulator systems in three patients (two bilateral).RESULTS: We followed these patients for an average of eight months, and the average pain reduction was 50%. We did not observe any adverse events during or immediately after surgery. One patient developed an adverse reaction to the adhesive of the battery transmitter, but it was not severe enough to stop her from using the stimulator.CONCLUSIONS: Considering the ease of implant and minimal side effects, implant of peripheral nerve stimulators to stimulate the occipital nerve is a promising treatment modality for patients with chronic headache who present with features of occipital neuralgia. However, wider use of this treatment modality is subject to further studies.

    Abstract

    Background: Low back pain (LBP) and neck pain are major causes of pain and disability that are experienced across all ages. The primary goals of treatment are to improve patient function and facilitate a return to the patient's desired level of daily activity. Therapeutic ultrasound is a noninvasive modality widely utilized in the management of musculoskeletal disorders, but there continues to be controversy regarding its use due to insufficient evidence of effectiveness. The objective of this systematic review was to evaluate the effectiveness of therapeutic ultrasound in the management of patients with chronic LBP and neck pain.Methods: Using PRISMA guidelines, a search of the PubMed and CENTRAL (The Cochrane Library) databases was performed to retrieve randomized controlled trials (RCTs) that evaluated therapeutic ultrasound in patients with chronic LBP or neck pain.Results: The search strategy identified 10 trials that met the criteria for inclusion. Three studies in LBP reported that both therapeutic and sham (placebo) ultrasound provided significant improvement in pain intensity. In each of these studies, ultrasound was found to be more effective than placebo when using only one of several validated instruments to measure pain. Three of the four studies on neck pain demonstrated significant pain relief with ultrasound in combination with other treatment modalities. However, only one of these studies demonstrated that the use of ultrasound was the cause of the statistically significant improvement in pain intensity.Conclusions: Therapeutic ultrasound is frequently used in the treatment of LBP and neck pain and is often combined with other physiotherapeutic modalities. However, given the paucity of trials and conflicting results, we cannot recommend the use of monotherapeutic ultrasound for chronic LBP or neck pain. It does seem that ultrasound may be considered as part of a physical modality treatment plan that may be potentially helpful for short-term pain relief; however, it is undetermined which modality may be superior. In both pain syndromes, further trials are needed to define the true effect of low-intensity ultrasound therapy for axial back pain. No conclusive recommendations may be made for optimal settings or session duration.

    Abstract

    Treatments for joint pain and dysfunction focus on restoration of joint motion, improvement in pain and a return to the previous level of the patient's daily activity. Therapeutic ultrasound is a noninvasive modality widely utilized in the management of musculoskeletal disorders. The objective of this systematic review was to evaluate the effectiveness of therapeutic ultrasound in the management of patients with knee, shoulder and hip pain.Using PRISMA guidelines, a search of the PubMed, CENTRAL (The Cochrane Library), Web of Science and Scopus databases was performed to retrieve randomized controlled trials (RCTs) that evaluated therapeutic ultrasound (continuous and pulsed) in patients with chronic knee, shoulder and hip pain.The search strategy identified 8 trials for knee, 7 trials for shoulder and 0 trials for hip that met the criteria for inclusion. All 8 trials showed improvement in knee pain, and of these studies 3 showed statistical significance improvement for therapeutic ultrasound versus the comparator. For shoulder pain, all 7 trials showed reduction in pain, but should be noted that 4 of studies demonstrated that therapeutic ultrasound is inferior to the comparator modality.Therapeutic ultrasound is frequently used in the treatment of knee, shoulder and hip pain and is often combined with other physiotherapeutic modalities. The literature on knee arthritis is most robust, with some evidence supporting therapeutic ultrasound, though the delivery method of ultrasound (pulsed vs continuous) is controversial. As a monotherapy, ultrasound treatment may not have a significant impact on functional improvement but can be a reasonable adjunct to consider with other common modalities. In all three pain syndromes, especially for hip pain, further trials are needed to define the true effect of low-intensity ultrasound therapy knee, shoulder and hip pain. No conclusive recommendations may be made for optimal settings or session duration.

    Abstract

    Hip denervation comprising radiofrequency lesioning of the obturator and femoral articular branches is used in adults with refractory hip pain who are not surgical candidates. Persistent hip pain infrequently occurs in pediatric patients and there is limited data on the safety and efficacy of this procedure in a pediatric population. We provide a case report of a successful ultrasound and fluoroscopic-guided hip denervation procedure in an 11-year old female with persistent right hip pain after septic arthritis refractory to conservative and surgical management strategies. At an 18- week follow-up, hip denervation provided improvement in pain, mobility, and reduced opioid consumption by 20%. This article is protected by copyright. All rights reserved.

    Abstract

    Approximately 10% of patients following a variety of surgeries develop chronic postsurgical pain. Reducing chronic postoperative pain is especially important to reconstructive surgeons because common operations such as breast and limb reconstruction have even higher risk for developing chronic postsurgical pain. Animal studies of posttraumatic nerve injury pain demonstrate that there is a critical time frame before and immediately after nerve injury in which specific interventions can reduce the incidence and intensity of chronic neuropathic pain behaviors-so called "preventative analgesia." In animal models, perineural local anesthetic, systemic intravenous local anesthetic, perineural clonidine, systemic gabapentin, systemic tricyclic antidepressants, and minocycline have each been shown to reduce pain behaviors days to weeks after treatment. The translation of this work to humans also suggests that brief perioperative interventions may protect patients from developing new chronic postsurgical pain. Recent clinical trial data show that there is an opportunity during the perioperative period to dramatically reduce the incidence and severity of chronic postsurgical pain. The surgeon, working with the anesthesiologist, has the ability to modify both early and chronic postoperative pain by implementing an evidence-based preventative analgesia plan.

  • Evaluating the management of septic shock using patient simulation CRITICAL CARE MEDICINE Ottestad, E., Boulet, J. R., Lighthall, G. K. 2007; 35 (3): 769-775

    Abstract

    Develop a scoring system that can assess the management of septic shock by individuals and teams.Retrospective review of videotapes of critical care house staff managing a standardized simulation of septic shock.Academic medical center; videotapes were made in a recreated intensive care unit environment using a high-fidelity patient simulator.Residents in medicine, surgery, and anesthesiology who had participated in the intensive care unit rotation.The septic patient was managed by the intensive care unit team in a graded manner with interns present for the first 10 mins and more senior-level help arriving after 10 mins. The intern was graded separately for the first 10 mins, and the team was graded for the entire 35-min performance.Both technical and nontechnical scoring systems were developed to rate the management of septic shock. Technical scores are based on guidelines and principles of managing septic shock. Team leadership, communication, contingency planning, and resource utilization were addressed by the nontechnical rating. Technical scores were calculated for both interns and teams; nontechnical scores applied only to the team. Of 16 technical checklist items, interns completed a mean of 7 with a range of 1.5-11. Team technical ratings had a mean of 9.3 with a range of 3.3-13. Nontechnical scores showed similar intergroup variability with a mean of 26 and a range of 10-35. Technical and nontechnical scores showed a modest correlation (r = .40, p = .05). Interrater reliabilities for intern and team technical scores were both r = .96 and for nontechnical scores r = .88.Objective measures of both knowledge-based and behavioral skills pertinent to the management of septic shock were made. Scores identified both adequate and poor levels of performance. Such assessments can be used to benchmark clinical skills of individuals and groups over time and may allow the identification of interventions that improve clinical effectiveness in sepsis management.
