Decreased Length of Stay and Opioid Usage After Liver Cancer Surgery With Enhanced Recovery Pathway Implementation.

BACKGROUND AND OBJECTIVES: Enhanced recovery after surgery (ERAS) pathways are associated with better postoperative recovery; however, evidence is lacking in liver cancer surgery. This study aimed to evaluate the impact of an ERAS pathway in US veterans undergoing liver cancer surgery. METHODS: We initiated an ERAS pathway for liver cancer surgery with preoperative, intraoperative, and postoperative interventions, which included a novel regional anesthesia technique, erector spinae plane block, for multimodal analgesia management. A retrospective quality improvement study was conducted with patients undergoing elective open hepatectomy or microwave ablation of liver tumors before and after ERAS pathway implementation. RESULTS: With 24 patients in the post-ERAS group and 23 patients in the pre-ERAS group, we found a significant decreased length of stay in the ERAS group (4.1 days ± 3.9) compared with traditional care (8.6 days ± 7.1, P = .01) and decreased perioperative opioid consumption including intraoperative opioids (post-ERAS 49.8 mg ± 28.5 vs pre-ERAS 98 mg ± 42.3, P = 4.1E-5), postoperative opioids (post-ERAS 65.3 mg ± 59.9 vs pre-ERAS 175.7 mg ± 210.6, P = .018), and patient-controlled analgesia requirements (post-ERAS 0% vs pre-ERAS 50%, P < .001). CONCLUSION: The implementation of ERAS for liver cancer surgery in our veteran population translates into decreased length of stay and perioperative opioid consumption. Although this study is limited as a quality improvement project implemented at one institution with a small sample size, our results are clinically and statistically significant and sufficient to warrant further investigation into the efficacy of ERAS as the surgical needs of the US veteran population increase.

Peripheral nerve stimulation for the management of acute and subacute post-amputation pain: a randomized, controlled feasibility trial.

Introduction & aim: Temporary (60-day) percutaneous peripheral nerve stimulation (PNS) has demonstrated effectiveness for the treatment of chronic post-amputation pain, and this pilot study aims to evaluate the feasibility of temporary percutaneous PNS for the treatment of acute post-amputation pain. Patients & methods: Sixteen veterans undergoing lower extremity amputation received PNS and standard medical therapy or standard medical therapy alone. Results: The PNS group reported greater reductions in average phantom limb pain, residual limb pain and daily opioid consumption, and there were fewer participants taking opioids through 3 months post-amputation. Conclusion: This pilot study suggests that PNS is feasible in the acute postoperative period following lower limb amputation and may provide a non-pharmacologic analgesic therapy that lowers pain scores and reduces opioid consumption, and thus warrants further investigation.

A small study was done to evaluate placing a wire lead near a nerve to electrically stimulate it for 60 days after a leg amputation surgery to see if it helps reduce pain. The study looked at 16 veterans who had an amputation to their leg. These patients were divided into either a group that received nerve stimulation plus normal pain control medications or a group that just received pain medications. The group that received nerve stimulation had less pain in the remaining leg and less phantom pain (pain in the missing leg). They also required fewer narcotic medications. The study suggested that nerve stimulation may provide an effective way to manage pain after amputation and reduce the use of pain medications. Clinical Trial Registration Number: NCT03484429.

Battlefield Medicine: Anesthesia and Critical Care in the Combat Zone.

The US Military Joint Trauma System has been developed to mitigate the harsh conditions under which medical providers care for combat casualties and provide continuity of care from the battlefield to US medical centers. We review the components of this system with emphasis on combat trauma care under fire and the role of the anesthesiologist and intensivist in this continuum of care. An important link in the chain of survival is the Air Force Critical Care Aeromedical Transport Team, which provides critical care while transporting casualties from the theater to higher levels of care outside the war zone and home.

A Case Report of Peripheral Nerve Stimulation for Acute Neuropathic Pain in Guillain-Barre Syndrome.

Guillain-Barre syndrome (GBS) is a peripheral demyelinating neuromuscular disorder occasionally associated with pharmacologically refractory neuropathic pain. We present a case of acute neuropathic pain in a 22-year-old man with GBS managed with percutaneous peripheral nerve stimulation (PNS). Following implantation of leads in the bilateral sciatic, femoral, and brachial plexus nerve distribution, the patient experienced significant pain reduction in both the upper and lower extremities. Analgesic and anxiolytic medications were reduced by 33% on the first day and by 78% on day 21. PNS is a minimally invasive, nonpharmacologic modality for treating acute neuropathic pain in GBS patients.
