SARS-CoV-2 infection in hematological patients during allogenic stem cell transplantation: A double case report.

Despite severe immunosuppression due to conditioning chemotherapy for acute myeloid leukemia, COVID-19 did not lead to clinical deterioration or death, thus raising the question of the impact of immunosuppressive treatment on clinical course evolution.

Different anesthetic techniques associated with different incidences of chronic post-thoracotomy pain: low-dose remifentanil plus presurgical epidural analgesia is preferable to high-dose remifentanil with postsurgical epidural analgesia.

Objective: To investigate the relationships between 2 anesthetic techniques, or the extent of allodynia around the surgical wound, and the occurrence of chronic post-thoracotomy pain.

Design: Prospective, randomized study.

Setting: A single-institution, university hospital.

Combined ultrasound and nerve stimulation-guided thoracic epidural catheter placement for analgesia following anterior spine fusion in scoliosis.

Anterior spine fusion by thoracotomy is indicated for the treatment of idiopathic scoliosis. Although epidural (EP) analgesia represents the most effective way to provide adequate analgesia after thoracotomy, scoliosis patients have substantial anatomic variations that make EP catheter placement more difficult and often contraindicated. This case report describes a safe, effective technique for placing a thoracic EP catheter in a young patient undergoing anterior spine fusion surgery by thoracotomy.

How much does pharmacologic prophylaxis reduce postoperative vomiting in children? Calculation of prophylaxis effectiveness and expected incidence of vomiting under treatment using Bayesian meta-analysis.

Background: The authors calculated the effect size for treatments recommended for the pediatric population in the new Guidelines for the Management of Postoperative Nausea and Vomiting that should be implemented with the help of a new risk scale developed for children.

Methods: Six single-drug therapies and five combination treatments were subjected to a Bayesian analysis, with respect to the outcome reported, in a sequence that parallels their dates of publication. Based on the Bayes theorem, a posterior probability was calculated after inclusion of the data from the successive studies, to update a prior probability existing before inclusion of that study.

Delayed Horner's syndrome during a continuous infraclavicular brachial plexus block.

Horner's syndrome is a potential, albeit rare, feature of continuous infraclavicular brachial plexus local anesthetics infusion, mainly the result of anatomical considerations. Horner's syndrome may be described as an "unpleasant side effect" because it has no clinical consequences in itself. Nevertheless, patient discomfort and anxiety may reduce acceptance of the analgesic technique.

Somatosensory evoked potentials as an objective assessment of the sensory median nerve blockade after infraclavicular block.

Purpose: Median nerve somatosensory evoked responses (MnSSER) alterations were compared to clinical tests (cold and pinprick) variations, in 20 ASA I adult patients following infraclavicular block obtained with 40 mL ropivacaine 0.5% to assess first, the difference of time course of the respective electrophysiological and clinical signs, and second, the objectivity and the reproducibility of MnSSER changes.

Clinical Features: Four MnSSER derivations (Erb's point; cutaneous projection of peripheral end of brachial plexus; posterior neck at C6 level, frontal and controlateral parietal scalp) were monitored and recorded for retrospective analysis.

Intraoperative somatosensory evoked potentials to facilitate peripheral nerve release.

Purpose: The significance of intraoperative somatosensory evoked potentials (SSEP) monitoring is well known during spinal surgery. This technology could be beneficial during peripheral nerve surgery as well. In order to illustrate potential applications, two cases of successful peripheral nerve release demonstrated by on-line, intraoperative, SSEP are reported.

The anterior combined approach via a single skin injection site allows lower limb anesthesia in supine patients.

Purpose: Lower limb anesthesia (LLA) requires the combination of, at least, three-in-one and sciatic nerve (SCN) blocks. Anterior approaches are easier to perform with minimal discomfort in supine patients, specially for traumatology. Feasibility of a single needle entry combined approach is reported.
