Two cases are presented with serious complications related to TEA. In both cases, earlier reaction of the treating physicians to patient-reported sensory symptoms could have prevented the complicated course. The first case was a 73-year-old patient with bronchial carcinoma who underwent right lower lobe resection. In this case, dabigatran 150 mg/d (indication: permanent atrial fibrillation) had been discontinued 72 hours before surgery, and enoxaparin 80 mg (every 12 hours) had been started 11 hours after surgery. An epidural hematoma developed postoperatively. Magnetic resonance imaging (MRI) was performed only after paraplegia had developed the next day. Unfortunately, delayed hematoma evacuation could not prevent persistent paraplegia in this case, which was complicated by hospital-acquired pneumonia with sepsis and acute renal failure. The second case was a 39-year-old patient with ulcerative colitis and an initially undetected malposition of the epidural catheter. Immediately after test bolus injection, the patient reported paresthesia and overall discomfort, which however could not be safely attributed to either the test dose or the already started general anesthesia. The patient could only be extubated after stopping the epidural infusion. Accidental re-start of epidural infusion led to coma, conjugate eye deviation, and respiratory arrest, necessitating re-intubation. Computed tomography (CT) ruled out intracerebral pathology and showed a catheter position centrally in the spinal canal. Fortunately, no neurological deficits were detected after catheter removal.</p>","PeriodicalId":18203,"journal":{"name":"Local and Regional Anesthesia","volume":"14 ","pages":"117-124"},"PeriodicalIF":2.9,"publicationDate":"2021-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/87/d4/lra-14-117.PMC8318213.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39266197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe pain prevents normal ventilation and leads to atelectasis, consolidation, and pneumonia. Subsequently, these patients frequently develop respiratory failure and require intubation and critical care. Therefore, adequate analgesia is often a life-saving intervention. Anesthetic management of a 78-year-old kyphotic patient with T6, T7, and T9 rib fractures on the right and T10-12 vertebral compression fractures sustained in an accidental fall is presented. She had inadequate pain control and was unable to take a deep breath or cough. Her respiratory status was deteriorating, with tachypnea and worsening hypoxia, necessitating bi-level positive airway pressure (BiPAP) support. Since thoracic epidural analgesia was contraindicated owing to compressive vertebral fractures and to the pending respiratory failure, we opted for a unilateral erector spinae plane (ESP) block at the T7 level and bilateral retrolaminar (RL) blocks at the T10 level. Following the procedure, the pain was immediately relieved and the patient was able to take deep breaths. Shortly thereafter, her respiratory status improved, with the respiratory rate coming back close to the baseline. The patient was subsequently weaned from BiPAP support and discharged from the intensive care unit. While the combination of ESP and RL blocks is not routinely used in patients with multiple rib and vertebral compression fractures, our report indicates that it may be an excellent alternative for analgesia in situations where thoracic epidural and/or paravertebral blocks are contraindicated and when timely intervention could be potentially life-saving.</p>","PeriodicalId":18203,"journal":{"name":"Local and Regional Anesthesia","volume":"14 ","pages":"99-102"},"PeriodicalIF":2.9,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/2a/08/lra-14-99.PMC8214557.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39101924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
